部署到 ubuntu 后套接字 io 未连接(nginx、nodejs、reactjs)

[英]Socket io not connected after deploy to ubuntu (nginx, nodejs, reactjs)

我有 MERN 应用程序,使用 express 构建 api,使用 reactjs 构建客户端。

在我的本地计算机(Windows)中,客户端可以连接到套接字服务器。 onConnection 事件被触发。

1. 本地计算机 (Windows)

客户端:

socket.on('connect', () => {
     console.log('connected to the socket server');
}) // triggered and i can see the console.log in broser console

服务器端:

io.on('connection', () => {
     console.log('client connected to the socket server');
}) // triggered and i can see the console.log in terminal

2. VPS (Ubuntu 20, Nginx)

当我将服务器和客户端部署到 vps 时,套接字无法连接。 未触发连接事件

但是客户端是触发connect_error事件:

socket.on("connect_error", (error) => {
   console.log('socket connection error:', error.message) // socket connection error: server error
}); // this event is triggered

这是我的代码:

服务器端:

const server = app.listen(3000)
const io = socketio(server)

客户端:

const socket = io("http://103.150.60.132/api")

NGINX 配置:

server {
  listen 80;

  location / {
        root /var/www/bacotin/client; //reactjs build location
        index  index.html index.htm;
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
        try_files $uri $uri/ /index.html;
  }

  location /api {
        proxy_pass http://103.150.60.132:3000; // express api
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection 'upgrade';
        proxy_set_header Host $host;
        proxy_cache_bypass $http_upgrade;
  }

 
  location ~* \.io {
      proxy_set_header X-Real-IP $remote_addr;
      proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header Host $http_host;
      proxy_set_header X-NginX-Proxy false;

      proxy_pass http://localhost:3000;
      proxy_redirect off;

      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection "upgrade";
    }


}

更新:问题解决了,现在socket客户端可以连接到socket服务器了。

只需修改客户端代码:

由此:

const socket = io("http://103.150.60.132/api")

对此:

const socket = io("http://103.150.60.132")

但为什么?
