vue中websoket的使用

首先安装npm install --save  websocket-heartbeat-js@^1.0.7

在main.js中  引入并挂载全局方法

import WebsocketHeartbeatJs from 'websocket-heartbeat-js';
if (JSON.parse(getStore('userInfo'))!= null) {
    let userId = JSON.parse(getStore('userInfo')).id;
    let websocketHeartbeatJs = new WebsocketHeartbeatJs({
        // url: 'ws://192.168.0.68:8888/websocket/' + userId
        url: 'ws://192.168.0.22:8888/websocket/' + userId
　　　　　pongTimeout: 1800000,reconnectTimeout: 100

    });
    Vue.prototype.websocketHeartbeatJs = websocketHeartbeatJs;
}

　在app.vue中 建立连接

 mounted() {
    // console.log(JSON.parse(this.getStore("userInfo")),'--------JSON.parse(this.getStore("userInfo"))-------')
    if (JSON.parse(this.getStore("userInfo")).id != "") {
      // console.log(JSON.parse(this.getStore("userInfo")).id);
      if ("WebSocket" in window) {
        this.websocketHeartbeatJs.onopen = function() {};
        var that = this;
        this.websocketHeartbeatJs.onmessage = function(e) {
          // console.log(JSON.parse(e.data),'-------------JSON.parse(e.data)-----------------');
          that.$store.state.websocketMsg = JSON.parse(e.data);
        在store中存放webscoket信息
          // console.log(that.$store.state.websocketMsg);
        };
        this.websocketHeartbeatJs.onreconnect = function() {};
      } else {
        alert("当前浏览器 Not support websocket");
      }
    }
  },

　　在vue组件中使用

 computed: {
            websocketInfo() {
                return this.$store.state.websocketMsg;
             //创建完成时存在store中的信息
            }
        },
        watch: {
            websocketInfo: function (nv, ov) {
                console.log(nv);
                this.websocketSuccess = nv.result.success;
                this.websocketMsg = nv.result.message;
                console.log(this.websocketSuccess, '-----------websocketSuccess----------');
                console.log(this.websocketMsg, '----------websocketMsg-------------');
                //   console.log(nv.result.result.error.code);
                if (this.websocketSuccess == true && this.websocketMsg == "true") {
                    // 创建云盘成功后挂载云主机
                    if (nv.result.result.inventory != undefined) {
                        this.diskid = nv.result.result.inventory.uuid;
                        this.id = this.$store.state.vmId;  
                    }
                    this.$Notice.destroy({
                        name: "warning",
                        duration: 1
                    });
                    var imageNames = this.vmName == "" ? "" : "'" + this.vmName + "'";
                    this.$Notice.success({
                        title: this.operation == "" ?
                            this.$store.state.operationed : "云盘"+ imageNames + this.operation +"成功" 
                    });
                    this.getImagesList(this.pageSize, this.pageNumber);
                    this.$refs.child.getinfo();
                    this.$refs.child.chishihua();
                    this.value2 = true;
                    // 创建完成挂载云主机
                    if(this.operation == '' &&  this.$store.state.operationed == '创建镜像成功'){
                        this.guazai();
                    };
                    this.operation == "" ;
                } else if (
                    this.websocketSuccess == true &&
                    this.websocketMsg == "false"
                ) {
                    var str = nv.result.result.error.details;
                    // str = str.split("不")[0];
                    // console.log(str);
                    this.$Notice.warning({
                        title: str
                    });
                } else if (
                    this.websocketSuccess == true &&
                    this.websocketMsg == ""
                ) {
                    this.$Notice.warning({
                        title: this.$store.state.operationed + "创建中",
                        duration: 1
                    });
                }
            },
        },
