Question

我正在使用socket-io开发一个简单的本机聊天应用程序。当我在IIS服务器中发布代码时，它返回404错误。我不知道是什么导致了这个问题。我尝试了许多解决方案，但仍然面临相同的问题。请为我提供一些解决此问题的方法。

我正在使用Windows Server 2012 R2。 IIS版本-8.5

****** node version - 10.15.3 *****
****** npm version - 6.4.1   ******

** server.js **

   const express = require('express');
   const http = require('http');
   const socketio = require('socket.io');
   const port = process.env.PORT || 4001;
   const fetch = require('node-fetch');
   const app = express();
   const server = http.createServer(app);
   const io = socketio(server);

   io.sockets.on('connection', socket => {    
       console.log("connected");
   });

   server.listen(port, () => console.log(`Listening on port ${port}`));
