Docker + Node.JS + Socket.IO + Nginx（405和錯誤的握手方法）

Question

我有一個帶有react前端和nodeJS / PHP后端的docker容器化應用程序（在不同容器上工作）。 我已經為前端構建和PHP后端成功安裝了帶有中間容器（讓我們使用sencrypt certbot）的https，但是套接字池到nodejs后端存在一些問題。 當socket.io池啟動時，我在POST請求中收到錯誤：

[POST] https：//my.domain/socket.io/？EIO = 3＆transport = polling＆t = MlE0IBv

405不允許

當我試圖通過下一個Nginx構造防止這種情況發生時：

error_page 405 @nodejs;

我在下一條消息中得到了相同的錯誤代碼：

代碼：2消息：“錯誤的握手方法”

我的Nginx配置有一部分（nginx是單獨的docker容器）：

upstream node {
    ip_hash;
    server node:4000; //nodejs container
}

server {
    listen 80;
    // ...redirect to https
}

server {
    listen 443 ssl;

    // .... cert's and other settings


    // front-end static react build
    location / {
        try_files $uri /index.html =404;
    }
    location /static {
        try_files $uri @nodejs;
    }

    location @nodejs {
        proxy_pass http://node;
        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;
    }

    // without this string i just got "405 Not Allowed" nginx error page
    // with this string i got probably nodejs "Bad handshake method" error
    error_page 405 @nodejs; 
}

我的app.js服務器代碼：

const express = require('express');
const http = require('http');
const socketIO = require('socket.io');
const socketRouter = require('./sockets/index');
const app = express();

const server = http.Server(app);
const io = socketIO(server, {origins: '*:*'});

app.use(express.json());
app.use(express.urlencoded({ extended: true }));

io.on('connection', socketRouter.bind({}, io));

module.exports = server;

和index.js：

require('dotenv').config();
const app = require('./src/app');

const PORT = process.env.APP_PORT || 4000;
app.listen(PORT);

console.log('Application started on Port ' + PORT);
console.log('APP_ENV ' + process.env.APP_ENV);

問題解決了。 正確的配置是：

location /static {
    try_files $uri =404;
}

location /socket.io {
        proxy_pass http://node;
        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;
        add_header  Front-End-Https   on;
}

error_page 405 @nodejs;
