Tencent COS XML SDK for React Native

# 腾讯云对象存储 React Native SDK

## Fork from [cos-xml-react-native]

## (腾讯云COS文档，自行查看)[https://cloud.tencent.com/document/product/436/12159]

## fork 说明
1. 部分bug修复
2. 更新安卓SDK版本

### 安装 SDK

```
yarn add @wu_rong_tai/react-native-cos-xml
```

如果没有自动执行 `pod` 安装，请执行：

```
cd ios
pod install
```

### 开始使用

#### 1. 导入 SDK

```
import CosXmlReactNative from '@wu_rong_tai/react-native-cos-xml';
```

#### 2. 初始化服务

**使用临时密钥初始化**
```javascript
CosXmlReactNative.initWithSessionCredentialCallback({
    region: region
}, async () => {
  
    // 在此处获取后端 credentials 凭证信息
    const response = await fetch(STS_URL);
    const responseJson = await response.json();
    const credentials = responseJson.credentials;

    const sessionCredentials = {
        tmpSecretId: credentials.tmpSecretId,
        tmpSecretKey: credentials.tmpSecretKey,
        sessionToken: credentials.sessionToken,
        expiredTime: credentials.expiredTime,
        beginTime: credentials.startTime
    };

    return sessionCredentials;
});
```

**使用永久密钥进行本地调试**

```ts
const SECRET_ID: string = 'Your Secret ID'  // 腾讯云永久密钥 SecretID
const SECRET_KEY: string = 'Your Secret Key'  // 腾讯云永久密钥 SecretKey
// 使用永久密钥进行本地调试
CosXmlReactNative.initWithPlainSecret({
  region: region
}, {
  secretId: SECRET_ID,
  secretKey: SECRET_KEY
})
```

### 访问 COS 服务

#### 上传文件

```ts
const uploadRequest = {
  bucket: bucket,
  object: objectKey,
  // 文件本地 Uri 或者 路径
  fileUri: 'file://xxx'
}

// 上传 与 暂停后续传对象
// 注意如果是续传，请务必跟初始上传使用同一个 uploadRequest 对象 
CosXmlReactNative.upload(uploadRequest, 
  (processedBytes: number, targetBytes: number) => {
    // 回调进度
    console.log('put Progress callback : ', processedBytes, targetBytes)
    setProgress(processedBytes / targetBytes)
}).then((info) => {
  // info 包含上传结果
  console.log(info)
}).catch((e) => {
  console.log(e)
})
```

暂停上传请调用：

```ts
CosXmlReactNative.pause(uploadRequest)
```

#### 下载文件

```ts
// 下载对象
CosXmlReactNative.download({
  bucket: bucket,
  object: objectKey
}, (processedBytes: number, targetBytes: number) => {
  // 回调进度
  console.log('get Progress callback : ', processedBytes, targetBytes)
  setProgress(processedBytes / targetBytes)
}).then((filePath) => {
  // filePath 是保存到本地的路径
  setSource({uri: "file://" + filePath})
}).catch((e) => {
  console.log(e)
})
```
