无法使用 node.js 和 nginx 连接到 socket.io答案

【问题标题】：Unable to connect with socket.io using node.js and nginx无法使用 node.js 和 nginx 连接到 socket.io

【问题描述】：

我已经设置了一个 socket.io，node.js 在 nginx 后面运行。主域在 nginx 上运行，子域被代理到 node.js。所有 REST API 都工作正常，但是当涉及到套接字连接时，我确实在日志中看到了握手，但客户端显然无法获得响应。下面是来自 node.js 的日志，下面是我正在使用的配置。任何想法为什么它不起作用？

Nginx 配置：

upstream app_yourdomain {
    server 127.0.0.1:3000;
}

# the nginx server instance
server {
    listen 80;
    server_name mydomain.com;

    # pass the request to the node.js server with the correct headers and much more can be added, see nginx config options
    location / {
      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 true;
      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection "upgrade";

      tcp_nodelay on;
      proxy_pass http://app_yourdomain/;
      proxy_redirect off;
    }
 }

Socket.io 正在 127.0.0.1:3000 中运行。

【解决方案1】：

您是否正在运行足够新的 nginx 版本？ nginx 版本 1.3.13 中引入了 WebSocket 支持。 nginx -v 看看你有什么版本。另见https://chrislea.com/2013/02/23/proxying-websockets-with-nginx/

【讨论】：

我最近通过apt-get安装了它，最近升级了整个系统，但只运行了1.1.19。我现在会尝试升级它。
我正在从客户端连接套接字，那么如何在代码中访问它，我的意思是如何访问 var socket = io.connect('/explorer/socket',{ 'reconnect' : true, '重新连接延迟': 500 });
