基于mns的贝米钱包消息队列库
## Installation
```SHELL
npm install bmqb-mq --save
```
## Roles
* consumer: `MQConsumer(adapter, config)`
* producer: `MQProducer(adapter, config)`
* msg: `MQMSG({adapter, content, delay, priority})`
## Quick start
* 创建producer
```JS
const adapter = 'mns';
const mnsConfig = {
accountId: 'your-account-id',
accessKey: 'your-access-key',
secretKey: 'your-secret-key',
};
const producer = new MQProducer(adapter, mnsConfig);
// 获取一个queue producer
const queueProducer = producer.getQueueProducer('queueName');
// 生成一个MQMsg对象
const msg = new MQMsg({
adapter: 'mns', // 必填
content: {foo: 'bar'}, // 必填
delay: 10, // 延迟十秒
priority: 'high', // 优先级, 默认为 'normal'
});
// 接收内容, pushMsg方法将返回一个Promise对象
queueProducer.pushMsg(msg).then(message => {
// message 是一个MQMsg对象
}).catch(err => {
// ...
});
```
* 创建consumer：
```JS
const adapter = 'mns';
const mnsConfig = {
accountId: 'your-account-id',
accessKey: 'your-access-key',
secretKey: 'your-secret-key',
};
const consumer = new MQConsumer(adapter, mnsConfig);
// 获取一个queue consumer
const queueConsumer = consumer.getQueueConsumer('queueName');
// 接收内容, 注册一个循环任务
queueConsumer.popMsg((err, message) => {
// message 将是一个MQMsg对象
// ...
// 设置消息下次可见时间
queueConsumer.setMsgVisibility(message, 10);
// 确认这个消息，使得消息不会再次可见
queueConsumer.deleteMsg(message);
});
```
