Nginx下配置socket支持

    server {
        listen       80;
        server_name  test.domain.com;

        # 转发站页面
        location ^~ /socket/ {
                proxy_pass http://192.168.2.10:8080/socket/;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
        }
        
    }

异常情况如下
