無法使用node.js和nginx與socket.io連接

Question

我已經設置了一個socket.io，其中node.js在nginx后面運行。 主域在nginx上運行，子域正在代理node.js. 所有REST API都運行正常，但是當涉及到套接字連接時，我確實看到了日志中的握手，但客戶端顯然無法獲得響應。 下面是來自node.js的日志，下面是我正在使用的配置。 任何想法為什么它不起作用？

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在127.0.0.1:3000中運行。

你在運行一個足夠新的nginx版本嗎？ 在nginx版本1.3.13中引入了WebSocket支持。 nginx -v看你有什么版本。 另見https://chrislea.com/2013/02/23/proxying-websockets-with-nginx/
