Nginx通過在客戶端和后端服務器之間建立隧道來支持WebSockets通信。為了讓Nginx可以將來自客戶端的Upgrade請求發送到后端服務器，Upgrade和Connection的頭信息必須被顯式的設置。如下所示：

 location /wsapp/ { proxy_pass http://wsbackend; proxy_http_version 1.1; proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection "upgrade"; } 

一旦我們完成以上設置，Nginx就可以處理WebSocket連接了。

生產配置實例：

[root@beta-aaa01:/usr/local/openresty/nginx/conf/locations]$cat location aaa.bbbb.cn.conf 

    location  / { 
        proxy_pass http://10.0.0.3:8702/;
            proxy_http_version 1.1;
            proxy_redirect off;
            proxy_buffering off;
            proxy_set_header X-NginX-Proxy true;
            proxy_set_header Host $host;
            proxy_set_header Http-Host $http_host;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header REMOTE-HOST $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
 proxy_set_header Upgrade $http_upgrade; proxy_set_header Connection $connection_upgrade;
    }
