WebSocket Verbindung fehlgeschlagen mit Nginx, Nodejs und socket.io

Question

Ich versuche, Nodejs mit Nginx einzurichten. Aber wenn der Client versuchen, es keine Verbindung herstellen kann mit ...

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 

Wie websocket Komunikation aktivieren?

meine aktuellen nginx Config

Answer 1

erste, aktualisieren Sie Ihren nginx Server 1.3 oder höher.

Sekunde, mein nginx conf funktioniert. Sie können meinem conf folgen.

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"; 
    } 
}
