vue中开发webSocket

先安装 sockjs-client 和 stompjs

npm install sockjs-client
npm install stompjs

<template>
  <div>
    <el-row :gutter="5">

      <div class="head">WebSocket接收后端数据</div>

      <div class="block">
        {{content.age}}
      </div>
      <el-button type="primary">提交</el-button>


    </el-row>

  </div>
</template>

<script>
  import FloorDashboard from './FloorAndArea'
  import Stomp from "stompjs"
  import SockJS from "sockjs-client"

  export default {
    name: "Index",
    data() {
      return {
        content: ""
      }
    },
    mounted() {
      this.connect();
    },
    methods: {
      connect() {
        //连接SockJS的endpoint名称为"endpointOyzc"
        let socket = new SockJS('http://test.jd.com:8082/endpointOyzc');
        //使用STMOP子协议的WebSocket客户端
        let stompClient = Stomp.over(socket);

        //连接WebSocket服务端
        stompClient.connect({}, () => {
          //通过stompClient.subscribe订阅/topic/getResponse 目标(destination)发送的消息
          // stompClient.subscribe('/topic/getResponse', function (response) {  //广播监听数据
          stompClient.subscribe('/user/1/message', (response) => {
            let dataType = typeof response.body;
            switch (dataType) {
              case "string":
                this.content = JSON.parse(response.body);
                console.log("type is string");
                console.log(this.content);
                break;
              case "object":
                console.log(this.content);
                console.log("type is string");
                this.content = response.body;
            }
          });
        });
      }
    }
  }
