Question

这是为套接字连接实现的代码，但是没有用。我想创建一个聊天消息应用程序，以响应本机并使用Web端服务器的后端进行实时更新。我正在尝试将我的应用程序连接到套接字io，但无法正常工作。

我已经使用socket.IO-client来进行本机反应：

import SocketIOClient from 'socket.IO-client'

export default Class Socket extends Component{
  constructor(){
    super();
    var Live_URL = "https://xxx.xxxxxxx.xxx/"
    this.socket = SocketIOClient(Live_URL);
  }

  componentDidMount(){
    this.socket.connect();
    this.socket.on("connect", () => {
      console.log('connection.')
    });
  }
}

这是服务器端代码。...

module.exports = function(app, httpServer) {

    var socketioJWT = require('socketio-jwt');
    var io = require("socket.io").listen(httpServer);
    var clients = [];
    var connectedClientSocketIds = []; //for store socket all opened ids.
    var clientsStatus = {};

    io.use(socketioJWT.authorize({
        secret: global.hzConfig.jwtPrivateKey,
        handshake: true
    }));

    //for store all ffmpeg converting process (user for kill running process)
    var runningFfmpegCommands = {};

    /**
     * @description Socket connection in when user going to online
     */
    io.sockets.on("connect", function(socket){
console.log(socket)
}

我在控制台中收到这种错误。....

Error: server error
    at Socket.onPacket (socket.js:455)
    at XHR.<anonymous> (socket.js:278)
    at XHR.Emitter.emit (index.js:133)

    at Request.<anonymous> (polling-xhr.js:128)
    at Request.Emitter.emit (index.js:133)
    at Request.onData (polling-xhr.js:302)

请问有什么解决办法吗？

在我的本机应用程序中对我有用的解决方案：

import io from 'socket.io-client';

componentDidMount() {
   const socket = io.connect(url);
   socket.on('message', (data) => {});
}

如何使用用于聊天应用程序的socket.io将本机应用程序连接到实时URL服务器？
