## 代码演示

### 如何引入

```jsx import
import { Upload } from '@douyinfe/semi-ui';
```
### 基本

最基本的用法，在 children 内放置一个 Button，点击 children 内容（即放置的 Button）激活文件选择框，选择完成后自动开始上传

```jsx live=true width=48%
import React from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload } from '@douyinfe/semi-icons';

() => {
    return (
        <Upload action="https://api.semi.design/upload">
            <Button icon={<IconUpload />} theme="light">
                点击上传
            </Button>
        </Upload>
    );
};
```

### 文件名超长省略

通过 `showTooltip` 属性，自定义设置文件名弹出提示

当类型为 `boolean` 时，控制是否弹出提示

```jsx live=true width=48%
import React from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';

() => {
    const action = 'https://api.semi.design/upload';
    const button = (
        <Button icon={<IconUpload />} theme="light">
            点击上传
        </Button>
    );
    return (
        <>
            <Upload action={action} showTooltip={false}>
                {button}
            </Upload>
        </>
    );
}
```

当类型为 `object` 时，可以自定义弹出样式

```jsx live=true width=48%
import React from 'react';
import { Upload, Button, Tooltip } from '@douyinfe/semi-ui';

() => {
    const action = 'https://api.semi.design/upload';
    const button = (
        <Button icon={<IconUpload />} theme="light">
            点击上传
        </Button>
    );
    return (
        <>
            <Upload action={action} showTooltip={{ 
                renderTooltip: (content, children) => {
                    return <Tooltip content={content} position="bottom">{children}</Tooltip>
                } 
            }}>
                {button}
            </Upload>
        </>
    );
}
```

### 添加提示文本

通过 `prompt` 插槽，设置自定义提示文本  
通过 `promptPosition` 设置插槽位置，可选 `left`、`right`、`bottom`，默认为 `right`

```jsx live=true width=48%
import React from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload } from '@douyinfe/semi-icons';

() => {
    const action = 'https://api.semi.design/upload';
    const getPrompt = (pos, isListType) => {
        let basicStyle = { display: 'flex', alignItems: 'center', color: 'grey', height: isListType ? '100%' : 32 };
        let marginStyle = {
            left: { marginRight: 10 },
            right: { marginLeft: 10 },
        };
        let style = { ...basicStyle, ...marginStyle[pos] };

        return <div style={style}>请上传资格认证材料</div>;
    };
    const button = (
        <Button icon={<IconUpload />} theme="light">
            点击上传
        </Button>
    );
    const positions = ['right', 'left', 'bottom'];
    return (
        <>
            {positions.map((pos, index) => (
                <>
                    {index ? (
                        <div
                            style={{ marginBottom: 12, marginTop: 12, borderBottom: '1px solid var(--semi-color-border)' }}
                        ></div>
                    ) : null}
                    <Upload action={action} prompt={getPrompt(pos)} promptPosition={pos}>
                        {button}
                    </Upload>
                </>
            ))}
        </>
    );
};
```

当 listType 为 picture 时，promptPosition 位置的参照对象为图片墙列表整体

```jsx live=true width=48%
import React from 'react';
import { Upload } from '@douyinfe/semi-ui';
import { IconPlus } from '@douyinfe/semi-icons';

() => {
    const action = 'https://api.semi.design/upload';
    const getPrompt = (pos, isListType) => {
        let basicStyle = { display: 'flex', alignItems: 'center', color: 'grey', height: isListType ? '100%' : 32 };
        let marginStyle = {
            left: { marginRight: 10 },
            right: { marginLeft: 10 },
        };
        let style = { ...basicStyle, ...marginStyle[pos] };

        return <div style={style}>请上传认证材料</div>;
    };
    const defaultFileList = [
        {
            uid: '1',
            name: 'dy.jpeg',
            status: 'success',
            size: '130kb',
            url:
                'https://lf3-static.bytednsdoc.com/obj/eden-cn/ptlz_zlp/ljhwZthlaukjlkulzlp/root-web-sites/dy.png',
        },
        {
            uid: '5',
            name: 'resso.jpeg',
            percent: 50,
            size: '222kb',
            url:
                'https://lf3-static.bytednsdoc.com/obj/eden-cn/ptlz_zlp/ljhwZthlaukjlkulzlp/root-web-sites/Resso.png',
        },
    ];
    const positions = ['right', 'bottom'];
    return (
        <>
            {positions.map((pos, index) => (
                <>
                    {index ? (
                        <div
                            style={{ marginBottom: 12, marginTop: 12, borderBottom: '1px solid var(--semi-color-border)' }}
                        ></div>
                    ) : null}
                    <Upload
                        action={action}
                        prompt={getPrompt(pos, true)}
                        promptPosition={pos}
                        listType="picture"
                        defaultFileList={defaultFileList}
                    >
                        <IconPlus size="extra-large" />
                    </Upload>
                </>
            ))}
        </>
    );
};
```

### 点击头像触发上传

```jsx live=true width=48%
import React from 'react';
import { Upload, Avatar, Toast } from '@douyinfe/semi-ui';
import { IconCamera } from '@douyinfe/semi-icons';

() => {
    const [url, setUrl] = useState('https://lf3-static.bytednsdoc.com/obj/eden-cn/ptlz_zlp/ljhwZthlaukjlkulzlp/root-web-sites/dy.png');
    const onSuccess = (response, file) => {
        Toast.success('头像更新成功');
        setUrl('https://sf6-cdn-tos.douyinstatic.com/obj/ttfe/ies/semi/ttmoment.jpeg');
    };

    const style = {
        backgroundColor: 'var(--semi-color-overlay-bg)',
        height: '100%',
        width: '100%',
        display: 'flex',
        alignItems: 'center',
        justifyContent: 'center',
        color: 'var(--semi-color-white)',
    };
    
    const hoverMask = (<div style={style}>
        <IconCamera />
    </div>);

    const api = 'https://api.semi.design/upload';
    let imageOnly = 'image/*';

    return (
        <Upload
            className="avatar-upload"
            action={api}
            onSuccess={onSuccess}
            accept={imageOnly}
            showUploadList={false}
            onError={() => Toast.error('上传失败')}
        >
            <Avatar src={url} style={{ margin: 4 }} hoverMask={hoverMask} />
        </Upload>
    );
};
```

```css
.avatar-upload .semi-upload-add {
    border-radius: 50%; // 确保只有圆是点击热区
}
```

### 自定义上传属性

通过设置 `data`、`headers` 可添加自定义上传属性

```jsx live=true width=48%
import React from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload } from '@douyinfe/semi-icons';

() => {
    let action = 'https://api.semi.design/upload';
    let data = {
        role: 'ies',
        time: new Date().getTime(),
    };
    let headers = {
        'x-tt-semi': 'semi-upload',
    };
    return (
        <Upload action={action} data={data} headers={headers}>
            <Button icon={<IconUpload />} theme="light">
                点击上传
            </Button>
        </Upload>
    );
};
```

### 上传文件类型

通过 `accept 属性（`input` 的原生 `html` 属性）可以限制上传的文件类型。

`accept` 支持传入以下两种类型字符串：

- 文件后缀名集合（推荐），如 .jpg、.png 等；
- 文件类型的 MIME types 集合，可参考[MDN 文档](https://developer.mozilla.org/en-US/docs/Web/HTTP/Basics_of_HTTP/MIME_types/Complete_list_of_MIME_types)  

例如只允许用户上传 PNG 和 PDF 文件，`accept` 可以这样写： `accept = '.pdf,.png'` 或 `accept = 'application/pdf,image/png'`（将 PNG 与 PDF 的 MIME type 通过`,`连接起来即可）。

<Notice type="primary" title="注意事项">
    <div>Upload 会在内部拦截掉不符合 accept 格式的文件，当拦截到不符合格式要求的文件时，会触发 onAcceptInvalid 方法；</div>
    <div>accept 使用后缀可以避免因为浏览器或者操作系统的不同导致 file.type 与 MIME 不兼容问题。</div>
</Notice>


```jsx live=true width=48%
import React from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload } from '@douyinfe/semi-icons';

() => {
    let action = 'https://api.semi.design/upload';
    let imageOnly = 'image/*';
    let videoOnly = 'video/*';
    let fileLimit = '.pdf,.png,.jpeg';
    return (
        <>
            <Upload action={action} accept={imageOnly} style={{ marginBottom: 12 }}>
                <Button icon={<IconUpload />} theme="light">
                    上传图片
                </Button>
            </Upload>
            <Upload action={action} accept={videoOnly} style={{ marginBottom: 12 }}>
                <Button icon={<IconUpload />} theme="light">
                    上传视频
                </Button>
            </Upload>
            <Upload action={action} accept={fileLimit}>
                <Button icon={<IconUpload />} theme="light">
                    上传 PDF, PNG, JPEG
                </Button>
            </Upload>
        </>
    );
};
```

### 上传文件夹

通过传入 `directory` 为 `true`，可以支持上传文件夹下的所有文件

```jsx live=true
import React from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload } from '@douyinfe/semi-icons';

() => {
    let action = 'https://api.semi.design/upload';
    return (
        <>
            <Upload action={action} directory>
                <Button icon={<IconUpload />} theme="light">
                    上传文件夹
                </Button>
            </Upload>
        </>
    );
};
```

### 一次选中多个文件

通过设置 `multiple` 属性可以支持同时选中多个文件上传。

```jsx live=true width=48%
import React from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload } from '@douyinfe/semi-icons';

() => {
    let action = 'https://api.semi.design/upload';
    return (
        <Upload action={action} multiple>
            <Button icon={<IconUpload />} theme="light">
                点击上传
            </Button>
        </Upload>
    );
};
```

### 限制文件总数量

通过设置 `limit` 属性可以限制最大可上传的文件数  
当 `limit` 为1时，始终用最新上传的代替当前，并不会触发onExceed回调

```jsx dir="column" live=true width=48%
import React from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload } from '@douyinfe/semi-icons';

() => {
    let action = 'https://api.semi.design/upload';
    let limit = 1;
    let onChange = props => {
        console.log(props.fileList);
    };
    return (
        <Upload
            action={action}
            limit={limit}
            onChange={onChange}
        >
            <Button icon={<IconUpload />} theme="light">
                点击上传（最多{limit}项）
            </Button>
        </Upload>
    );
};
```

```jsx dir="column" live=true width=48%
import React from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload } from '@douyinfe/semi-icons';

() => {
    let action = 'https://api.semi.design/upload';
    let [disabled, setDisabled] = useState(false);
    let limit = 2;
    let onChange = props => {
        let length = props.fileList.length;
        if (length === limit) {
            setDisabled(true);
        } else {
            setDisabled(false);
        }
    };
    return (
        <Upload
            action={action}
            limit={limit}
            onExceed={() => Toast.warning(`最多只允许上传${limit}个文件`)}
            onChange={onChange}
        >
            <Button icon={<IconUpload />} theme="light" disabled={disabled}>
                点击上传（最多{limit}项）
            </Button>
        </Upload>
    );
};
```

照片墙模式下，当已上传文件数量等于 limit 时，会自动隐藏上传入口

```jsx live=true width=48%
import React from 'react';
import { Upload } from '@douyinfe/semi-ui';
import { IconPlus } from '@douyinfe/semi-icons';

() => {
    let action = 'https://api.semi.design/upload';
    const defaultFileList = [
        {
            uid: '1',
            name: 'dyBag.png',
            status: 'success',
            size: '130KB',
            preview: true,
            url: 'https://lf3-static.bytednsdoc.com/obj/eden-cn/ptlz_zlp/ljhwZthlaukjlkulzlp/root-web-sites/edit-bag.jpeg',
        },
        {
            uid: '2',
            name: 'dyBag2.jpeg',
            status: 'success',
            size: '222KB',
            preview: true,
            fileInstance: new File([new ArrayBuffer(2048)], 'dyBag2.jpeg', { type: 'image/png' }),
            url: 'https://lf3-static.bytednsdoc.com/obj/eden-cn/ptlz_zlp/ljhwZthlaukjlkulzlp/root-web-sites/edit-bag.jpeg',
        },
    ];
    return (
        <Upload
            action={action}
            limit={2}
            listType="picture"
            accept="image/*"
            defaultFileList={defaultFileList}
            onExceed={() => Toast.warning('最多只允许上传2个文件')}
        >
            <IconPlus size="extra-large" />
        </Upload>
    );
};
```

### 限制上传文件大小

通过 `maxSize` 和 `minSize` 属性可以自定义上传文件大小的限制，通过设置 `onSizeError` 可以设置超出限制时的回调。

```jsx live=true width=48%
import React from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload } from '@douyinfe/semi-icons';

() => {
    let action = 'https://api.semi.design/upload';

    return (
        <>
            <Upload
                action={action}
                maxSize={1024}
                minSize={200}
                onSizeError={(file, fileList) => Toast.error(`${file.name} size invalid`)}
            >
                <Button icon={<IconUpload />} theme="light">
                    点击上传（最小 200KB，最大 1MB）
                </Button>
            </Upload>
        </>
    );
};
```

### 自定义列表操作区

`listType` 为 `list` 时，可以通过传入 `renderFileOperation` 来自定义列表操作区

```jsx live=true width=48%
import React from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload, IconDownload, IconEyeOpened, IconDelete } from '@douyinfe/semi-icons';

() => {
    let action = 'https://api.semi.design/upload';

    const defaultFileList = [
        {
            uid: '1',
            name: 'dyBag.png',
            status: 'success',
            size: '130KB',
            preview: true,
            url: 'https://lf3-static.bytednsdoc.com/obj/eden-cn/ptlz_zlp/ljhwZthlaukjlkulzlp/root-web-sites/edit-bag.jpeg',
        }
    ];
    const renderFileOperation = (fileItem) => (
        <div style={{ display: 'flex', columnGap: 8, padding: '0 8px' }}>
            <Button icon={<IconEyeOpened></IconEyeOpened>} type="tertiary" theme="borderless" size="small"></Button>
            <Button icon={<IconDownload></IconDownload>} type="tertiary" theme="borderless" size="small"></Button>
            <Button onClick={e=>fileItem.onRemove()} icon={<IconDelete></IconDelete>} type="tertiary" theme="borderless" size="small"></Button>
        </div>
    );
    return <Upload action={action} defaultFileList={defaultFileList} itemStyle={{ width: 300 }} renderFileOperation={renderFileOperation}>
        <Button icon={<IconUpload />} theme="light">点击上传</Button>
    </Upload>;
};
```

### 自定义文件列表标题

`listType` 为 `list` 时，可以通过 `fileListTitle` 自定义文件列表顶部的标题区域。支持两种形式：

#### 字符串或 ReactNode 形式

当传入字符串或 ReactNode 时，仅替换标题文字，清空按钮保持默认样式：

```jsx live=true width=48%
import React from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload } from '@douyinfe/semi-icons';

() => {
    let action = 'https://api.semi.design/upload';

    const defaultFileList = [
        {
            uid: '1',
            name: 'document.pdf',
            status: 'success',
            size: '130KB',
        },
        {
            uid: '2',
            name: 'report.xlsx',
            status: 'success',
            size: '222KB',
        },
    ];

    return (
        <>
            <Upload 
                action={action} 
                defaultFileList={defaultFileList} 
                fileListTitle="已上传文件"
                style={{ marginBottom: 20 }}
            >
                <Button icon={<IconUpload />} theme="light">自定义标题文字</Button>
            </Upload>
            <Upload 
                action={action} 
                defaultFileList={defaultFileList} 
                fileListTitle={<span style={{ color: 'var(--semi-color-primary)', fontWeight: 600 }}>📁 重要文件</span>}
            >
                <Button icon={<IconUpload />} theme="light">带样式的标题</Button>
            </Upload>
        </>
    );
};
```

#### 函数形式

当传入函数时，可以完全自定义标题区域，包括清空按钮。函数会接收以下参数：
- `fileList`: 当前文件列表
- `onClear`: 清空文件的回调函数
- `clearText`: 清空按钮的默认文案（根据当前语言环境）

```jsx live=true width=48%
import React from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload, IconClose } from '@douyinfe/semi-icons';

() => {
    let action = 'https://api.semi.design/upload';

    const defaultFileList = [
        {
            uid: '1',
            name: 'document.pdf',
            status: 'success',
            size: '130KB',
        },
        {
            uid: '2',
            name: 'report.xlsx',
            status: 'success',
            size: '222KB',
        },
    ];

    return (
        <>
            <Upload 
                action={action} 
                defaultFileList={defaultFileList} 
                style={{ marginBottom: 20 }}
                fileListTitle={({ fileList, onClear, clearText }) => (
                    <div style={{ display: 'flex', alignItems: 'center', justifyContent: 'space-between', width: '100%' }}>
                        <span style={{ color: 'var(--semi-color-primary)' }}>
                            📂 共 {fileList.length} 个文件
                        </span>
                        <Button 
                            size="small" 
                            type="danger" 
                            icon={<IconClose />}
                            onClick={onClear}
                        >
                            {clearText}
                        </Button>
                    </div>
                )}
            >
                <Button icon={<IconUpload />} theme="light">自定义清空按钮样式</Button>
            </Upload>
            <Upload 
                action={action} 
                defaultFileList={defaultFileList} 
                fileListTitle={({ fileList, onClear }) => (
                    <div style={{ display: 'flex', alignItems: 'center', justifyContent: 'space-between', width: '100%' }}>
                        <span>
                            已选择 <strong style={{ color: 'var(--semi-color-danger)' }}>{fileList.length}</strong> 个文件
                        </span>
                        <span 
                            onClick={onClear}
                            style={{ 
                                cursor: 'pointer', 
                                color: 'var(--semi-color-link)',
                                fontSize: 12
                            }}
                        >
                            全部移除
                        </span>
                    </div>
                )}
            >
                <Button icon={<IconUpload />} theme="light">完全自定义标题区域</Button>
            </Upload>
        </>
    );
};
```

### 自定义预览逻辑

`listType` 为 `list` 时，可以通过传入 `previewFile` 览逻辑  
例如你不需要对图片类型进行缩略图预览时，可以在 `previewFile` 中恒定返回一个`<IconFile />`  
假如你希望点击图片时放大预览，则可以在 `previewFile`中使用 Image 组件  
或者你希望使用额外的操作区来实现点击放大预览，你也可以结合 `renderFileOperation` 放置一些自定义元素例如 Icon 图标实现点击放大  

```jsx live=true width=48%
import React from 'react';
import { Upload, Button, Image } from '@douyinfe/semi-ui';
import { IconUpload, IconFile } from '@douyinfe/semi-icons';

() => {
    let action = 'https://api.semi.design/upload';
    const defaultFileList = [
        {
            uid: '1',
            name: 'dyBag.png',
            status: 'success',
            size: '130KB',
            url: 'https://lf3-static.bytednsdoc.com/obj/eden-cn/ptlz_zlp/ljhwZthlaukjlkulzlp/root-web-sites/edit-bag.jpeg',
        },
        {
            uid: '2',
            name: 'dyBag2.png',
            status: 'success',
            size: '130KB',
            url: 'https://lf3-static.bytednsdoc.com/obj/eden-cn/ptlz_zlp/ljhwZthlaukjlkulzlp/root-web-sites/edit-bag.jpeg',
        },
    ];
    return (
        <Upload
            defaultFileList={defaultFileList}
            action={action}
            previewFile={file => file.uid === '1' ? <IconFile size="large" /> : <Image src={file.url} />}
        >
            <Button icon={<IconUpload />} theme="light">
                点击上传
            </Button>
        </Upload>
    );
};
```

结合 renderFileOperation 与 ImagePreview 的示例，以下示例点击右侧第一个 Icon 可放大图片预览
```jsx live=true
import React, { useStae } from 'react';
import { Upload, Button, ImagePreview } from '@douyinfe/semi-ui';
import { IconUpload, IconDownload, IconEyeOpened, IconDelete, IconExpand } from '@douyinfe/semi-icons';

() => {
    let action = 'https://api.semi.design/upload';
    const [visible, setVisible] = useState(false);
    const defaultFileList = [
        {
            uid: '1',
            name: 'dyBag.png',
            status: 'success',
            size: '130KB',
            preview: true,
            url: 'https://lf3-static.bytednsdoc.com/obj/eden-cn/ptlz_zlp/ljhwZthlaukjlkulzlp/root-web-sites/edit-bag.jpeg',
        }
    ];
    const renderFileOperation = (fileItem) => (
        <div style={{ display: 'flex', columnGap: 8, padding: '0 8px' }}>
            <Button
                icon={<IconExpand></IconExpand>}
                type="tertiary"
                theme="borderless"
                size="small"
                onClick={()=> setVisible(true)}
            >
            </Button>
            <Button icon={<IconDownload></IconDownload>} type="tertiary" theme="borderless" size="small"></Button>
            <Button onClick={e=>fileItem.onRemove()} icon={<IconDelete></IconDelete>} type="tertiary" theme="borderless" size="small"></Button>
            <ImagePreview
                src={fileItem.url}
                visible={visible}
                onVisibleChange={setVisible}
            />
        </div>
    );
    return <Upload action={action} defaultFileList={defaultFileList} itemStyle={{ width: 300 }} renderFileOperation={renderFileOperation}>
        <Button icon={<IconUpload />} theme="light">点击上传</Button>
    </Upload>;
};

```

### 默认文件列表

通过 `defaultFileList` 可以展示已上传的文件。当需要预览默认文件的缩略图时，你可以将 `defaultFileList` 内对应 `item` 的 `preview` 属性设为 `true`

<Notice title='注意事项'>
    defaultFileList中 uid 必须唯一，不可重复
</Notice>


```jsx live=true width=48%
import React from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload } from '@douyinfe/semi-icons';

() => {
    let action = 'https://api.semi.design/upload';

    const defaultFileList = [
        {
            uid: '1',
            name: 'dyBag.jpeg',
            status: 'success',
            size: '130KB',
            preview: true,
            url: 'https://lf3-static.bytednsdoc.com/obj/eden-cn/ptlz_zlp/ljhwZthlaukjlkulzlp/root-web-sites/edit-bag.jpeg',
        },
        {
            uid: '2',
            name: 'dyBag2.jpeg',
            status: 'uploadFail',
            size: '222KB',
            preview: true,
            fileInstance: new File([new ArrayBuffer(2048)], 'dyBag2.jpeg', { type: 'image/png' }),
            url: 'https://lf3-static.bytednsdoc.com/obj/eden-cn/ptlz_zlp/ljhwZthlaukjlkulzlp/root-web-sites/edit-bag.jpeg',
        },
    ];

    return (
        <>
            <Upload action={action} defaultFileList={defaultFileList}>
                <Button icon={<IconUpload />} theme="light">
                    点击上传
                </Button>
            </Upload>
        </>
    );
};
```

### 受控组件

当传入`fileList`时，作为受控组件使用。需要监听 onChange 回调，并且将 fileList 回传给 Upload（注意需传入一个新的数组对象）

```jsx live=true width=48%
import React from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload } from '@douyinfe/semi-icons';

() => {
    const initList = [
        {
            uid: '1',
            name: 'dyBag.jpeg',
            status: 'success',
            size: '130KB',
            preview: true,
            url: 'https://lf3-static.bytednsdoc.com/obj/eden-cn/ptlz_zlp/ljhwZthlaukjlkulzlp/root-web-sites/edit-bag.jpeg',
        },
        {
            uid: '2',
            name: 'dy.jpeg',
            status: 'uploading',
            size: '222KB',
            percent: 50,
            preview: true,
            fileInstance: new File([new ArrayBuffer(2048)], 'dy.jpeg', { type: 'image/jpeg' }),
            url:
                'https://lf3-static.bytednsdoc.com/obj/eden-cn/ptlz_zlp/ljhwZthlaukjlkulzlp/root-web-sites/dy.png',
        },
    ];

    const [list, updateList] = useState(initList);

    const onChange = ({ fileList, currentFile, event }) => {
        console.log('onChange');
        console.log(fileList);
        console.log(currentFile);
        let newFileList = [...fileList]; // spread to get new array
        updateList(newFileList);
    };

    return (
        <Upload
            action="https://api.semi.design/upload"
            onChange={onChange}
            fileList={list}
            showRetry={false}
        >
            <Button icon={<IconUpload />} theme="light">
                点击上传
            </Button>
        </Upload>
    );
};
```

### 图片墙

设置 `listType = 'picture'`，用户可以上传图片并在列表中显示缩略图  
如果通过 defaultFileList 或 fileList 设置已上传的文件列表时，会自动读取对象数组中的 url 属性用于展示图片

```jsx live=true width=48%
import React from 'react';
import { Upload } from '@douyinfe/semi-ui';
import { IconPlus } from '@douyinfe/semi-icons';

() => {
    let action = 'https://api.semi.design/upload';
    const defaultFileList = [
        {
            uid: '1',
            name: 'dy.png',
            status: 'success',
            size: '130KB',
            preview: true,
            url:
                'https://lf3-static.bytednsdoc.com/obj/eden-cn/ptlz_zlp/ljhwZthlaukjlkulzlp/root-web-sites/dy.png',
        },
    ];
    return (
        <>
            <Upload action={action} listType="picture" accept="image/*" multiple defaultFileList={defaultFileList}>
                <IconPlus size="extra-large" />
            </Upload>
        </>
    );
};
```

设置 `showPicInfo`，可以查看图片基础信息

```jsx live=true width=48%
import React from 'react';
import { Upload } from '@douyinfe/semi-ui';
import { IconPlus } from '@douyinfe/semi-icons';

() => {
    let action = 'https://api.semi.design/upload';
    const defaultFileList = [
        {
            uid: '1',
            name: 'music.png',
            status: 'success',
            size: '130KB',
            preview: true,
            url:
                'https://lf3-static.bytednsdoc.com/obj/eden-cn/ptlz_zlp/ljhwZthlaukjlkulzlp/root-web-sites/Resso.png',
        },
        {
            uid: '2',
            name: 'brand.png',
            status: 'success',
            size: '130KB',
            preview: true,
            url:
                'https://lf3-static.bytednsdoc.com/obj/eden-cn/ptlz_zlp/ljhwZthlaukjlkulzlp/root-web-sites/Resso.png',
        },
    ];
    return (
        <>
            <Upload action={action} listType="picture" showPicInfo accept="image/*" multiple defaultFileList={defaultFileList}>
                <IconPlus size="extra-large" />
            </Upload>
        </>
    );
};
```

### 图片墙放大预览
配合 Image 组件，通过 renderThumbnail API ，可以实现点击图片放大预览

```jsx live=true width=48%
import React from 'react';
import { Upload, Image } from '@douyinfe/semi-ui';
import { IconPlus } from '@douyinfe/semi-icons';

() => {
    let action = 'https://api.semi.design/upload';
    const defaultFileList = [
        {
            uid: '1',
            name: 'music.png',
            status: 'success',
            size: '130KB',
            preview: true,
            url:
                'https://lf3-static.bytednsdoc.com/obj/eden-cn/ptlz_zlp/ljhwZthlaukjlkulzlp/root-web-sites/Resso.png',
        }
    ];
    return (
        <>
            <Upload
                action={action}
                listType="picture"
                accept="image/*"
                multiple
                defaultFileList={defaultFileList}
                renderThumbnail={(file) => (<Image src={file.url} />)}
            >
                <IconPlus size="extra-large" />
            </Upload>
        </>
    );
};
```

可以通过 `renderPicPreviewIcon`，`onPreviewClick` 来自定义预览图标，当显示替换图标 `showReplace` 时，不会再显示预览图标<br />
当需要自定义预览/替换功能时，需要关闭替换功能，使用 `renderPicPreviewIcon` 监听图标点击事件即可。<br />
`onPreviewClick` 监听的是单张图片容器的点击事件

```jsx live=true width=48%
import React from 'react';
import { Upload } from '@douyinfe/semi-ui';
import { IconPlus, IconEyeOpened } from '@douyinfe/semi-icons';

() => {
    let action = 'https://api.semi.design/upload';
    const defaultFileList = [
        {
            uid: '1',
            name: 'resso.png',
            status: 'success',
            size: '130KB',
            preview: true,
            url:
                'https://lf3-static.bytednsdoc.com/obj/eden-cn/ptlz_zlp/ljhwZthlaukjlkulzlp/root-web-sites/Resso.png',
        },
    ];
    const handlePreview = (file) => {
        const feature = "width=300,height=300";
        window.open(file.url, 'imagePreview', feature);
    };
    return (
        <>
            <Upload
                action={action}
                listType="picture"
                showPicInfo
                accept="image/*"
                multiple
                defaultFileList={defaultFileList}
                onPreviewClick={handlePreview}
                renderPicPreviewIcon={()=><IconEyeOpened style={{ color: 'var(--semi-color-white)', fontSize: 24 }} />}
            >
                <IconPlus size="extra-large" />
            </Upload>
        </>
    );
};
```

### 图片墙设置宽高
通过设置 picHeight, picWidth （ v2.42 后提供），可以统一设置图片墙元素的宽高
如果同时使用 `renderThumbnail` return Image 组件来实现点击放大预览，你需要同时指定 Image 组件的 width 和 height

```jsx live=true dir="column"
import React from 'react';
import { Upload } from '@douyinfe/semi-ui';
import { IconPlus } from '@douyinfe/semi-icons';

() => {
    let action = 'https://api.semi.design/upload';
    const defaultFileList = [
        {
            uid: '1',
            name: 'image-1.jpg',
            status: 'success',
            size: '130KB',
            preview: true,
            url:
                'https://lf3-static.bytednsdoc.com/obj/eden-cn/ptlz_zlp/ljhwZthlaukjlkulzlp/root-web-sites/abstract.jpg',
        }
    ];
    return (
        <>
            <Upload
                action={action}
                listType="picture"
                accept="image/*"
                multiple
                defaultFileList={defaultFileList}
                picHeight={110}
                picWidth={200}
                renderThumbnail={(file) => (<Image src={file.url} width={200} height={110} />)}
            >
                <IconPlus size="extra-large" style={{ margin: 4 }} />
                点击添加图片
            </Upload>
        </>
    );
};
```

设置 `hotSpotLocation` 自定义点击热区的顺序，默认在照片墙列表结尾

```jsx live=true width=48%
import React from 'react';
import { Upload, Select, RadioGroup, Radio } from '@douyinfe/semi-ui';
import { IconPlus, IconEyeOpened } from '@douyinfe/semi-icons';

() => {
    let action = 'https://api.semi.design/upload';
    const defaultFileList = [
        {
            uid: '1',
            name: 'resso.png',
            status: 'success',
            size: '130KB',
            preview: true,
            url:
                'https://lf3-static.bytednsdoc.com/obj/eden-cn/ptlz_zlp/ljhwZthlaukjlkulzlp/root-web-sites/Resso.png',
        },
    ];
    const handlePreview = (file) => {
        const feature = "width=300,height=300";
        window.open(file.url, 'imagePreview', feature);
    };
    const [hotSpotLocation, setLocation] = useState('end');
    return (
        <>
            <RadioGroup
                value={hotSpotLocation}
                type='button'
                onChange={e => setLocation(e.target.value)}>
                <Radio value='start'>start</Radio>
                <Radio value='end'>end</Radio>
            </RadioGroup>
            <hr />
            <Upload
                action={action}
                listType="picture"
                showPicInfo
                accept="image/*"
                multiple
                hotSpotLocation={hotSpotLocation}
                defaultFileList={defaultFileList}
                onPreviewClick={handlePreview}
            >
                <IconPlus size="extra-large" />
            </Upload>
        </>
    );
};
```

### 禁用

```jsx live=true width=48%
import React from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload } from '@douyinfe/semi-icons';

() => {
    const defaultFileList = [
        {
            uid: '1',
            name: 'first.png',
            status: 'success',
            size: '130KB',
            preview: true,
            url: 'https://lf3-static.bytednsdoc.com/obj/eden-cn/ptlz_zlp/ljhwZthlaukjlkulzlp/root-web-sites/dy.png',
        },
        {
            uid: '2',
            name: 'second.png',
            status: 'validateFail',
            size: '222KB',
            preview: true,
            url: 'https://lf3-static.bytednsdoc.com/obj/eden-cn/ptlz_zlp/ljhwZthlaukjlkulzlp/root-web-sites/dy.png',
        },
    ];
    let action = 'https://api.semi.design/upload';
    return (
        <>
            <Upload action={action} disabled defaultFileList={defaultFileList}>
                <Button icon={<IconUpload />} theme="light" disabled>
                    点击上传
                </Button>
            </Upload>
        </>
    );
};
```

### 手动触发上传

`uploadTrigger='custom'`，选中文件后将不会自动触发上传。需要手动调用 `ref` 上的 `upload` 方法触发

```jsx live=true width=48%
import React, { useRef } from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload, IconPlus } from '@douyinfe/semi-icons';

function ManulUploadDemo() {
    const uploadRef = useRef();
    const manulUpload = () => {
        uploadRef.current && uploadRef.current.upload();
    };

    let action = 'https://api.semi.design/upload';
    return (
        <div>
            <Upload
                accept="image/gif, image/png, image/jpeg, image/bmp, image/webp"
                action={action}
                uploadTrigger="custom"
                ref={uploadRef}
                onSuccess={(...v) => console.log(...v)}
                onError={(...v) => console.log(...v)}
            >
                <Button icon={<IconPlus />} theme="light" style={{ marginRight: 8 }}>
                    选择文件
                </Button>
            </Upload>
            <Button icon={<IconUpload />} theme="light" onClick={manulUpload}>
                开始上传
            </Button>
        </div>
    );
}
```

### 拖拽上传

`draggable='true'`，可以使用拖拽功能
<Notice type="primary" title="注意事项">
    <div>在directory为true的情况下，因为浏览器自动做了限制，所以点击上传时不允许选单个文件，拖拽时我们认为同时允许文件夹、文件都能拖动更合理，所以不做另外的拦截处理。</div>
</Notice>

```jsx live=true width=48%
import React from 'react';
import { Upload } from '@douyinfe/semi-ui';

() => (
    <Upload
        action="https://api.semi.design/upload"
        draggable={true}
        dragMainText={'点击上传文件或拖拽文件到这里'}
        dragSubText="支持任意类型文件"
    ></Upload>
);
```

可以通过 `dragIcon`、`dragMainText`、`dragSubText` 快捷设置拖拽区内容

```jsx live=true width=48%
import React from 'react';
import { Upload } from '@douyinfe/semi-ui';
import { IconBolt } from '@douyinfe/semi-icons';

() => <Upload
    action="https://api.semi.design/upload"
    dragIcon={<IconBolt />}
    draggable={true}
    accept="application/pdf,.jpeg"
    dragMainText={'点击上传文件或拖拽文件到这里'}
    dragSubText="仅支持jpeg、pdf"
    style={{ marginTop: 10 }}
></Upload>;
```

还可以通过 `children` 传入 ReactNode，完全自定义拖拽区的显示

```jsx live=true width=48%
import React from 'react';
import { Upload } from '@douyinfe/semi-ui';
import { IconBolt } from '@douyinfe/semi-icons';

() => (<Upload
    action="https://api.semi.design/upload"
    dragIcon={<IconBolt />}
    draggable={true}
    accept="application/pdf,.jpeg"
    style={{ marginTop: 10 }}
>
    <div className="components-upload-demo-drag-area">
        <img
            src="https://lf3-static.bytednsdoc.com/obj/eden-cn/ptlz_zlp/ljhwZthlaukjlkulzlp/root-web-sites/dy.png"
            height="96"
            alt='demo img'
            style={{ borderRadius: 4 }}
        />
        <div
            style={{
                fontSize: 14,
                marginTop: 8,
                flexBasis: '100%',
                textAlign: 'center',
                color: 'var(--semi-color-tertiary)',
            }}
        >
            Wow, you can really dance.
        </div>
    </div>
</Upload>
);
```

Scss 样式如下

```scss
.components-upload-demo-drag-area {
    border-radius: var(--semi-border-radius-small);
    border: 2px dashed var(--semi-color-border);
    width: 100%;
    padding: 12px;
    background-color: var(--semi-color-tertiary-light-default);
    display: flex;
    cursor: pointer;
    flex-wrap: wrap;
    justify-content: center;
    &:hover {
        background-color: var(--semi-color-primary-light-default);
        border-color: var(--semi-color-primary);
    }
}
```

### 上传前自定义校验

可通过 `beforeUpload` 钩子，对文件状态进行更新，这是在网络上传前，选择文件后进行校验，`({ file: FileItem, fileList: Array<FileItem> }) => beforeUploadResult | Promise | boolean` 同步校验时需返回 boolean（true 为校验通过，false 为校验失败，校验失败会阻止文件网络上传）或者一个 Object 对象，具体结构如下

```ts
// beforeUploadResult:
{
    fileInstance?: File,
    status?: 'success' | 'uploadFail' | 'validateFail' | 'validating' | 'uploading' | 'wait',
    validateMessage?: React.ReactNode | string, // 文件的校验信息
    shouldUpload: boolean, // 是否需要上传。默认为true，如果为false，该fileItem只会被展示在列表中，不会触发上传操作
    autoRemove: boolean, // 是否从fileList中移除该文件，默认为false
}
```

```jsx live=true width=48%
import React, { useRef } from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload } from '@douyinfe/semi-icons';

function ValidateDemo() {
    const countRef = useRef(0);

    const transformFile = (fileInstance) => {
        if (countRef.current === 0) {
            return new File([fileInstance], 'newFileName', { type: 'image/png' });
        }
        return fileInstance;
    };

    const beforeUpload = ({ file, fileList }) => {
        let result;
        if (countRef.current > 0) {
            result = {
                autoRemove: false,
                fileInstance: file.fileInstance,
                shouldUpload: true,
            };
        } else {
            result = {
                autoRemove: false,
                fileInstance: file.fileInstance,
                status: 'validateFail',
                shouldUpload: false,
            };
        }
        countRef.current = countRef.current + 1;
        return result;
    };

    return (
        <Upload action="https://api.semi.design/upload" transformFile={transformFile} beforeUpload={beforeUpload}>
            <Button icon={<IconUpload />} theme="light">
                点击上传（上传前同步校验）
            </Button>
        </Upload>
    );
}
```

异步校验时，需返回 Promise，Promise resolve 代表检验通过，reject 代表校验失败，不会触发上传。  
resolve/reject 时可以传入 object（结构同上 beforeUploadResult）

```jsx live=true width=48%
import React, { useRef } from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload } from '@douyinfe/semi-icons';

function AsyncBeforeUploadDemo() {
    const countRef = useRef(0);
    const beforeUpload = ({ file, fileList }) => {
        return new Promise((resolve, reject) => {
            if (countRef.current > 1) {
                const result = {
                    autoRemove: false,
                    shouldUpload: true,
                };
                countRef.current = countRef.current + 1;
                resolve(result);
            } else {
                const result = {
                    autoRemove: false,
                    fileInstance: file.fileInstance,
                    status: 'validateFail',
                    shouldUpload: false,
                    validateMessage: `第${countRef.current + 1}个注定失败`,
                };
                countRef.current = countRef.current + 1;
                reject(result);
            }
        });
    };

    return (
        <Upload action="https://api.semi.design/upload" beforeUpload={beforeUpload}>
            <Button icon={<IconUpload />} theme="light">
                点击上传（上传前异步校验）
            </Button>
        </Upload>
    );
}
```

### 上传后更新文件信息

可以通过 `afterUpload` 钩子，对文件状态，校验信息，文件名进行更新。  
`({ response: any, file: FileItem, fileList: Array<FileItem> }) => afterUploadResult`  
`afterUpload` 在上传完成后(`xhr.onload`)且没有发生错误的情况下触发，需返回一个 Object 对象（不支持异步返回），具体结构如下

```ts
// afterUploadResult:
{
    status?: 'success' | 'uploadFail' | 'validateFail' | 'validating' | 'uploading' | 'wait';
    // 文件的校验信息
    validateMessage?: React.ReactNode | string;
    // 是否从fileList中移除该文件，默认为false
    autoRemove?: boolean;
    // 文件的名称
    name?: string;
    // 预览文件的url，一般为当次上传请求中 Server 接收到文件后返回的存储地址，v2.63后支持传入。
    // 之前的版本也可以通过 onChange 中结合 status 手动更新受控 fileList 中的属性实现
    url?: string 
}
```

```jsx live=true width=48%
import React from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload } from '@douyinfe/semi-icons';

() => {
    const afterUpload = ({ response, file }) => {
        // 可以根据业务接口返回，决定当次上传是否成功
        if (response.status_code === 200) {
            return {
                autoRemove: false,
                status: 'uploadFail',
                validateMessage: '内容不合法',
                name: 'RenameByServer.jpg',
                url: 'https://lf3-static.bytednsdoc.com/obj/eden-cn/ptlz_zlp/ljhwZthlaukjlkulzlp/root-web-sites/edit-bag.jpeg'
            };
        } else {
            return {};
        }
    };

    return (
        <Upload action="https://api.semi.design/upload" afterUpload={afterUpload}>
            <Button icon={<IconUpload />} theme="light">
                点击上传
            </Button>
        </Upload>
    )
}
```

### 自定义请求

当传入 customRequest 时, 相当于使用的自定义的请求方法替换了 upload 内置的 xhr 请求，用户需要自行接管上传行为。  
可在入参中获取到当前操作的 file 对象，用户自行实现上传过程，并且在适当的时候调用 customRequest 入参中的 onProgress、onError、onSuccess 以更新 Upload 组件内部状态进而驱动 UI 更新  
customRequest 包含以下入参

```ts
{
    // 当前文件名称
    fileName: string,
    // 用户设置的props.data
    data: object,
    // FileItem，具体结构参考下面的文档
    file: FileItem,
    // original File Object which extends Blob, 浏览器实际获取到的文件对象(https://developer.mozilla.org/zh-CN/docs/Web/API/File)
    fileInstance: File,
    // 上传过程中应调用的函数，event需要包含 total、loaded属性
    onProgress: (event: { total: number, loaded: number }) => any,
    // 上传出错时应调用的函数
    onError: (userXhr: { status: number }, e: event) => any,
     // 上传成功后应调用的函数, response为上传成功后的请求结果
    onSuccess: (response: any, e?: event) => any,
    // 用户设置的props.withCredentials
    withCredentials: boolean,
    // 用户设置的props.action
    action: string,
}
```

```jsx live=true width=48%
import React from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload } from '@douyinfe/semi-icons';

() => {
    const mockRequest = ({ file, onProgress, onError, onSuccess }) => {
        let count = 0;
        let interval = setInterval(() => {
            if (count === 100) {
                clearInterval(interval);
                onSuccess();
                return;
            }
            onProgress({ total: 100, loaded: count });
            count += 20;
        }, 500);
    };

    return (
        <Upload action="https://api.semi.design/upload" customRequest={mockRequest}>
            <Button icon={<IconUpload />} theme="light">
                点击上传
            </Button>
        </Upload>
    );
};
```

### 图片裁切

通过 `crop` 属性启用图片裁切功能。支持点击选择、拖拽、粘贴、替换文件时进行裁切。

#### 基本用法

设置 `crop={true}` 启用默认裁切配置。

```jsx live=true width=48%
import React from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload } from '@douyinfe/semi-icons';

() => {
    return (
        <Upload
            action="https://api.semi.design/upload"
            crop={true}
            onSuccess={(response, file) => {
                console.log('上传成功:', response, file);
            }}
        >
            <Button icon={<IconUpload />} theme="light">
                点击上传（启用裁切）
            </Button>
        </Upload>
    );
};
```

#### 自定义裁切配置

通过对象形式配置裁切参数，包括宽高比、形状、质量等。

```jsx live=true width=48%
import React from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload } from '@douyinfe/semi-icons';

() => {
    return (
        <Upload
            action="https://api.semi.design/upload"
            crop={{
                aspectRatio: 16 / 9,
                shape: 'rect',
                quality: 0.8,
                modalTitle: '裁切图片',
                modalOkText: '确认裁切',
                modalCancelText: '取消',
            }}
            onSuccess={(response, file) => {
                console.log('上传成功:', response, file);
            }}
        >
            <Button icon={<IconUpload />} theme="light">
                点击上传（16:9 裁切）
            </Button>
        </Upload>
    );
};
```

#### 圆形裁切

适用于头像上传场景，设置 `shape: 'round'` 启用圆形裁切。

```jsx live=true width=48%
import React from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload } from '@douyinfe/semi-icons';

() => {
    return (
        <Upload
            action="https://api.semi.design/upload"
            crop={{
                aspectRatio: 1,
                shape: 'round',
                quality: 0.9,
                modalTitle: '裁切头像',
            }}
            onSuccess={(response, file) => {
                console.log('上传成功:', response, file);
            }}
        >
            <Button icon={<IconUpload />} theme="light">
                点击上传（圆形裁切）
            </Button>
        </Upload>
    );
};
```

#### 裁切前确认

通过 `beforeCrop` 回调，在裁切前进行确认或其他处理。返回 `false` 可跳过裁切直接上传。

```jsx live=true width=48%
import React from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload } from '@douyinfe/semi-icons';

() => {
    return (
        <Upload
            action="https://api.semi.design/upload"
            crop={{
                aspectRatio: 1,
                shape: 'round',
            }}
            beforeCrop={(file, fileList) => {
                console.log('beforeCrop:', file, fileList);
                // 返回 true 继续裁切，返回 false 跳过裁切直接上传
                return window.confirm('是否裁切图片？');
            }}
            onCropError={(error) => {
                console.error('裁切失败:', error);
            }}
            onSuccess={(response, file) => {
                console.log('上传成功:', response, file);
            }}
        >
            <Button icon={<IconUpload />} theme="light">
                点击上传（裁切前确认）
            </Button>
        </Upload>
    );
};
```

#### 拖拽上传裁切

拖拽上传时也会触发裁切功能。

```jsx live=true width=48%
import React from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload } from '@douyinfe/semi-icons';

() => {
    return (
        <Upload
            action="https://api.semi.design/upload"
            crop={{
                aspectRatio: 1,
                shape: 'rect',
            }}
            draggable
            onDrop={(e, files, fileList) => {
                console.log('拖拽文件:', files);
            }}
            onSuccess={(response, file) => {
                console.log('上传成功:', response, file);
            }}
        >
            <Button icon={<IconUpload />} theme="light">
                拖拽上传（启用裁切）
            </Button>
        </Upload>
    );
};
```

#### 自定义裁切弹窗样式

通过 `cropModalProps` 自定义裁切弹窗的样式和属性。

```jsx live=true width=48%
import React from 'react';
import { Upload, Button } from '@douyinfe/semi-ui';
import { IconUpload } from '@douyinfe/semi-icons';

() => {
    return (
        <Upload
            action="https://api.semi.design/upload"
            crop={{
                aspectRatio: 1,
                shape: 'rect',
            }}
            cropModalProps={{
                width: 800,
                style: { height: 600 },
                bodyStyle: { height: 500, backgroundColor: '#f5f5f5' },
            }}
            onSuccess={(response, file) => {
                console.log('上传成功:', response, file);
            }}
        >
            <Button icon={<IconUpload />} theme="light">
                自定义弹窗样式
            </Button>
        </Upload>
    );
};
```
