一、先安装依赖插件

二、组件中的使用

// 先安装stompjs
npm install stompjs

utils文件中的mqtt.js内容:

mqtt.js

export const MQTT_SERVICE = 'ws://10.38.128.82:15674/ws' // mqtt服务地址
export const MQTT_USERNAME = 'tx' // mqtt连接用户名
export const MQTT_PASSWORD = 'tx' // mqtt连接密码
export const MQTT_host = 'tx' // mqtt交换机
export const MQTT_topic = '/exchange/PC_MESSAGE_LIINZHI/PC' // 订阅频道

组件中代码:test.vue

 

import Stomp from 'stompjs'
import { MQTT_SERVICE, MQTT_USERNAME, MQTT_PASSWORD,MQTT_host,MQTT_topic } from '@/utils/mqtt'

export default {
  data() {
    return {
      title:'测试信息',
      client: Stomp.client(MQTT_SERVICE),
      listData: [
      ]
    }
  },
  computed: {
    optionSetting() {
      return {
        step: 1, // 速度,值越大,速度越快
        hoverStop: true // 鼠标悬停效果,false为关闭该效果
        //           singleHeight: 120,//单行停顿
        //           waitTime: 2500,//单行停顿的时间
      }
    }
  },
  created() {
    this.connect()// stomp连接mq
  },
  methods: {
    onConnected: function(frame) {
      // 订阅频道
      const topic = MQTT_topic
      this.client.subscribe(topic, this.responseCallback, this.onFailed)
    },
    onFailed: function(frame) {
      console.log('MQ Failed:' + frame)
    },
    responseCallback: function(frame) {
    // 接收消息处理
      console.log('MQ msg=>', frame.body)
      this.title=frame.body;
    },
    connect() {
    // 初始化mqtt客户端,并连接mqtt服务
      const headers = {
        login: MQTT_USERNAME,
        password: MQTT_PASSWORD
      }
this.client.connect(MQTT_USERNAME,MQTT_PASSWORD, this.onConnected, this.onFailed,MQTT_host)
     // this.client.connect(MQTT_USERNAME,MQTT_PASSWORD, this.onConnected, this.onFailed)//   有的是不需要MQTT_host的,不需要的话,就不用传这个参数
    }
  }
}
