vue中若需要连接连个不同的socket地址,可以创建多个socket对象

socket.js

import http from "../js/axios";
import pako from "pako";
import store from "../../store/index";
import vue from "vue";
let ws1;
let ws2;
export const connect = () => {
  connect1();
  connect2();
};

let connect1 = () => {
  ws1 = new WebSocket("ws://api.huobiasia.vip/ws");
  send1();
};
let connect2 = () => {
  ws2 = new WebSocket("ws://8.210.219.206:2340");
  send2();
};
const send1 = () => {
  ws1.onopen = function() {
    // Web Socket 已连接上,使用 send() 方法发送数据
    // console.log(111111111, "已连接");
    http.get("/api/getInstruments").then(data => {
      let coin;
      // eslint-disable-next-line no-unused-vars
      let query1;
      let query3;
      data.forEach(item => {
        coin = item.instrument_id
          .split("-")
          .join("")
          .toLowerCase();
        vue.set(item, "coin", coin);
        store.commit("saveCoin", data);
        query1 = {
          sub: "market." + coin + ".depth.step0",
          id: "id1"
        };
        query3 = {

          id: "id1"
        };
        ws1.send(JSON.stringify(query1));
        ws1.send(JSON.stringify(query3));
        ws1.onmessage = res => {
          // console.log("blob类型数据: " + res.data); //blob
          let reader = new FileReader();
          reader.readAsArrayBuffer(res.data, "utf-8");

              })
            );
            // console.log("ArrayBuffer转字符串", msg);

            if (msg.ping) {
              ws1.send(JSON.stringify({ pang: msg.ping }));
            } else {
              store.commit("detail", msg);
            }
          };
        };
      });
    });
  };

  ws1.onclose = function() {
    // 关闭 websocket
    console.log("连接已关闭...");
    connect1();
  };
};
const send2 = () => {
  ws2.onopen = function() {
    http.get("/api/getInstruments").then(data => {
      let query2;
      // let query3;
      data.forEach(item => {
        query2 = "market.subscribe,spot/candle86400s:" + item.instrument_id;
        ws2.send(query2);
        ws2.onmessage = data => {
          if (data.data == "pong") {
            // ws2.send("ping");
          } else {
            let msg = JSON.parse(data.data);
            if (msg.market) {
              store.commit("detail", msg);
            }
          }
        };
      });
    });
  };

  ws2.onclose = function() {
    // 关闭 websocket
    console.log("连接已关闭...");
    connect();
  };
};
export const close = () => {
  ws1.close();
  ws2.close();
};

在main.js引入并调用connect()
