【问题描述】:
我有一个带有 react 前端和 nodeJS/PHP 后端的 docker 容器化应用程序(在不同的容器上工作)。我已经成功地为我的前端构建和 PHP 后端安装了带有中间容器(let'sencrypt certbot)的 https,但是与 nodejs 后端的套接字池有一些问题。当 socket.io pooling 开始时,我收到了关于 POST 请求的错误:
[发布]https://my.domain/socket.io/?EIO=3&transport=polling&t=MlE0IBv
405 不允许
当我试图通过下一次 Nginx 构建来防止这种情况时:
error_page 405 @nodejs;
我得到了与下一条消息相同的错误代码:
代码:2 消息:“握手方法错误”
我的 Nginx 配置中有一部分(nginx 是单独的 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 服务器代码:
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;
还有 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);
