vue实现与websocket实现长链接



    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 = 127.0.0.1:8080 + "/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);
           // 接收数据
        console.log(redata.value); 
      }, 

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

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