Vue中使用websocket的正确使用方法

 目前发现使用没什么问题,可以先使用

<template>
  <div class="test">

  </div>
</template>

<script>
  export default {
    name : 'test',
    data() {
      return {
        websock: null,
      }
    },
    created() {
      this.initWebSocket();
    },
    destroyed() {
      this.websock.close() //离开路由之后断开websocket连接
    },
    methods: {
      initWebSocket(){ //初始化weosocket
        const wsuri = "ws://127.0.0.1:8080";
        this.websock = new WebSocket(wsuri);
        this.websock.onmessage = this.websocketonmessage;
        this.websock.onopen = this.websocketonopen;
        this.websock.onerror = this.websocketonerror;
        this.websock.onclose = this.websocketclose;
      },
      websocketonopen(){ //连接建立之后执行send方法发送数据
        let actions = {"test":"12345"};
        this.websocketsend(JSON.stringify(actions));
      },
      websocketonerror(){//连接建立失败重连
        this.initWebSocket();
      },
      websocketonmessage(e){ //数据接收
        const redata = JSON.parse(e.data);
      },
      websocketsend(Data){//数据发送
        this.websock.send(Data);
      },
      websocketclose(e){  //关闭
        console.log('断开连接',e);
      },
    },
  }
</script>
<style lang='less'>
 
</style>

Vue+WebSocket 实现页面实时刷新长连接

数据实时刷新,使用h5新增的WebSocket来实现数据实时展示

<template>
    <div>
    </div>
</template>

<script>
    export default {
        data() {
            return {
                websock: null,
            }
        },
    created(){
           //页面刚进入时开启长连接
            this.initWebSocket()
       },
    destroyed: function() {
    //页面销毁时关闭长连接
      this.websocketclose();
    },
    methods: { 
      initWebSocket(){ //初始化weosocket 
       
        const wsuri = process.env.WS_API + "/websocket/threadsocket";//ws地址
        this.websock = new WebSocket(wsuri); 
        this.websocket.onopen = this.websocketonopen;

        this.websocket.onerror = this.websocketonerror;

        this.websock.onmessage = this.websocketonmessage; 
        this.websock.onclose = this.websocketclose;
       }, 

      websocketonopen() {
        console.log("WebSocket连接成功");
      },
      websocketonerror(e) { //错误
        console.log("WebSocket连接发生错误");
      },
      websocketonmessage(e){ //数据接收 
        const redata = JSON.parse(e.data);
         //注意:长连接我们是后台直接1秒推送一条数据, 
          //但是点击某个列表时,会发送给后台一个标识,后台根据此标识返回相对应的数据,
      //这个时候数据就只能从一个出口出,所以让后台加了一个键,例如键为1时,是每隔1秒推送的数据,为2时是发送标识后再推送的数据,以作区分
        console.log(redata.value); 
      }, 

      websocketsend(agentData){//数据发送 
        this.websock.send(agentData); 
      }, 

      websocketclose(e){ //关闭 
        console.log("connection closed (" + e.code + ")"); 
     },
   }, 
  }
 </script>
