WebSocket接続がnginx、nodejs、socket.ioで失敗しました

Question

nginxでnodejsを設定しようとしています。しかし、クライアントが接続しようとすると失敗する...

WebSocket connection to 'ws://www.mydomain.com/socket.io/1/websocket/KUv5G...' failed: Error during WebSocket handshake: 'Connection' header value is not 'Upgrade': keep-alive socket.io.js:2371 

どのようにWebSocket通信を有効にするには？

私の現在のnginxの設定

    server 127.0.0.1:3000 max_fails=0 fail_timeout=10s weight=1; 
    ip_hash;

まず、あなたのnginxのサーバーが1.3以上にアップグレードしてください。

秒、私のnginx conf works.you私のconfに従うことができます。

server { 
    listen  80; 
    server_name jn.whattoc.com; 

    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_pass http://127.0.0.1:4050/; 
     proxy_redirect off; 

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