node.js - 在 Heroku 上托管时出现 socket.io 问题

Question

我在将代码服务器上传到 Heroku 时遇到问题。没有套接字连接消息。 这是Heroku上服务器端的代码

var appS = require('express')();
var http = require('http').Server(appS);
var io = require('socket.io')(http,{path: '/octagon/socket.io'});
http.listen(3000, function(){
  console.log('listening on *:3000');
});


io.sockets.on('connection', function (socket) { 

  socket.on('test',function (message) {

    console.log(message)
  })
})

这是客户端的代码

var socket  = io.connect('https://murmuring-waters-83521.herokuapp.com/',
                {
                    reconnect: true,
                    transports : ['websocket'],
                    ressources: '/octagon/socket.io'
                });

我仍然收到此消息

WebSocket connection to 'wss://murmuring-waters-83521.herokuapp.com/octagon/socket.io/?EIO=3&transport=websocket' failed: Error during WebSocket handshake: Unexpected response code: 503

Answer 1

您可以通过更新客户端配置来使其工作

var socket  = io('//murmuring-waters-83521.herokuapp.com',
  {
      reconnect: true,
      rejectUnauthorized: false, // new
      path: '/octagon/socket.io' // use this instead of `ressources`
  });
  socket.on('connection', function () {
    alert('Browser is connected to server!');
  });
