代码语言：javascript复制

Upgrade: websocket

关键参数：Upgrade

nginx在反向代理的时候 少转发了头，添加上就可以了。

       proxy_set_header Upgrade $http_upgrade;
           proxy_set_header Connection "upgrade";

完整配置：

           client_max_body_size 500M;
           client_body_buffer_size 10M;
           fastcgi_intercept_errors on;
           proxy_connect_timeout   60;
           proxy_send_timeout      60;
           proxy_read_timeout      60;
           proxy_http_version       1.1;
