Socket.IO and NodeJs behing Nginx ( HTTPS ). xhr polling requests canceled

问题

如果我的解释不好，请写下评论！
我遇到了一个奇怪的问题，我有一个使用NodeJs Express 5.0的socket.io服务器。
我有socket.io客户端从Windows/MacOS/Linux连接，使用任何Web浏览器都可以建立socket.io连接，没有任何问题。

但是从Android/Ios应用程序不起作用，我在nginx中没有收到任何错误，也没有在nodejs应用程序中收到任何错误。
我唯一看到的错误是在使用USB调试和chrome://inspect/#devices -> 标签（networking）中。
在标签中我看到：这个请求状态为（挂起）半秒钟，然后变为（已取消）

  1. URL: mydomain.com/socket.io/?EIO=4&transport=polling&t=Oc7fPq6 
  2. STATUS: canceled
  3. TYPE: xhr
  4. SIZE: 0 B

更新!!!! 这是来自Android应用程序的错误日志

  1. 2023-07-25 14:37:30.426 9286-9482/com.myandroidapp.app E/chromium: [ERROR:ssl_client_socket_impl.cc(978)] handshake failed; returned -1, SSL error code 1, net_error -202

服务器（Socket.IO和Express代码）：

  1. let SocketServer = require('./core/socket_server.js');
  2. const bodyparser = require('body-parser');
  4. const cors = require('cors');
  5. const express = require('express');
  6. const app = express();
  8. const server = require('http').createServer(app);
  10. const io = require('socket.io')(server, {
  11.   cors: {
  12.     origin: "*",
  13.     methods: ["GET", "POST"],
  14.     transports: ['websocket', 'xhr-polling'],
  15.     credentials: false
  16.   },
  17.   allowEIO3: true
  18. });
  20. let SockServer = new SocketServer(io);
  22. app.set('view engine', 'ejs');
  23. app.use(bodyparser.json());
  25. app.use('/call/:room_id/:user_id/:video_state', express.static('public'));
  27. app.get('/call/:room_id/:user_id/:video_state', async (request, response) => {
  29.   await response.render('video_chat', {
  30.       room_id: request.params.room_id,
  31.       user_id: request.params.user_id,
  32.       video_state: Number(request.params.video_state)
  33.       });
  34. });
  36. server.listen(5001, "0.0.0.0");
  37. SockServer.ServerInitialize();
  39. app.use(cors({

我尝试添加transports: ['websocket', 'xhr-polling', 'polling']。

英文:

If my explanation is bad, please write a comment !
I encounter a strange problem, i have a socket.io Server using NodeJs Express 5.0.
I have socket.io clients that connects from Windows/MacOS/Linux using any WebBrowser, and connection of socket.io is established without any problems.

But from Android/Ios Application is not working, i don't get any error in nginx, or in nodejs app.
The only error i see is using usb-debugging and chrome://inspect/#devices -> tab (networking).
In the Tab i see: This requests as STATUS (pending) for half of a second, and after that it's (canceled)

  1. URL: mydomain.com/socket.io/?EIO=4&transport=polling&t=Oc7fPq6 
  2. STATUS: canceled
  3. TYPE: xhr
  4. SIZE: 0 B

Oh my god,
使用以下方式成功解决了：

ssl_certificate /etc/certificates/fullchain.pem;

而不是：

ssl_certificate /etc/certificates/cert.pem;

英文:

Oh my god,
Got it worked by using this:

  1. ssl_certificate /etc/certificates/fullchain.pem;

Instead of:

  1. ssl_certificate /etc/certificates/cert.pem;
