腾讯云消息队列的nodejs SDK

API文档 https://www.qcloud.com/doc/api/431/5832

队列操作接口

• CreateQueue(queueName, maxMsgHeapNum, pollingWaitSeconds, visibilityTimeout, maxMsgSize, msgRetentionSeconds, next(err, data) {})
• ListQueue (searchWord, offset, limit, next(err, data) {})
• GetQueueAttributes (queueName, next(err, data) {})
• SetQueueAttributes (queueName, maxMsgHeapNum, pollingWaitSeconds, visibilityTimeout, maxMsgSize, msgRetentionSeconds, next(err, data) {})
• DeleteQueue (queueName, next (err, data) {})

消息操作

• SendMessage (queueName, msgBody, next(err, data) {})
• BatchSendMessage (queueName, msgBodys, next(err, data) {})
• ReceiveMessage (queueName, pollingWaitSeconds, next(err, data) {})
• BatchReceiveMessage (queueName, numOfMsg, pollingWaitSeconds, next(err, data) {})
• DeleteMessage (queueName, receiptHandle, next(err, data) {})
• BatchDeleteMessage (queueName, receiptHandles, next(err, data) {})

Example

// 创建cmq对象，`http://cmq-queue-gz.api.qcloud.com`需要根据你的服务器自行填写，参考： https://www.qcloud.com/doc/api/431/5832
const cmq = new CMQ('your SecretId', 'your SecretKey', 'http://cmq-queue-gz.api.qcloud.com')
cmq.CreateQueue('yourQueueName', (err,data) => {
  console.log('CreateQueue', err, data)
})

how to notifyMessage?

var _signStop = false
var notifyStop = function () {
  _signStop = true
}
var notifyRecv = function (queueName, done) {
  cmq.ReceiveMessage(queueName, 5, function (err, data) {
    if (_signStop) {
      console.log('notifyRecv is stop!')
      _signStop = false
      return
    }
    if (err) {
      console.log('notifyRecv-error', err)
    } else if (data.code === 0) {
      console.log('a message', data)
      if (done) {
        cmq.DeleteMessage(queueName, data.receiptHandle, (err, data) => {
          console.log('DeleteMessage', err, data)
        })
      }
      notifyRecv(queueName, done)
    } else {
      console.log('no message', data)
      notifyRecv(queueName, done)
    }
  })
}

notifyRecv('test779361906', true)

setTimeout(function () {
  notifyStop()
}, 10000)
