websocket使用nginx代理后连接频繁打开和关闭

location /ctm01expvideo-web/ {

        proxy_set_header   Host             $http_host;

        proxy_set_header   X-Real-IP        $remote_addr;

        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;

        proxy_set_header   X-Forwarded-Proto  $scheme;

        //新添加

        proxy_set_header Upgrade "websocket";

        //新添加

        proxy_set_header Connection "upgrade";

        proxy_pass http://10.194.98.123:36099/ctm01expvideo-web/;

}

上面的配置可以使代理端口支持websocket协议，重启nginx后404报错消失，但是又出现如下报错：

查阅资料后发现是配置有问题，重新修改nginx配置文件：

location /ctm01expvideo-web/ {

        proxy_set_header   Host             $http_host;

        proxy_set_header   X-Real-IP        $remote_addr;

        proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;

        proxy_set_header   X-Forwarded-Proto  $scheme;

        //新添加

        proxy_set_header Upgrade "websocket";

        //新添加

        proxy_set_header Connection "upgrade";
        //新添加
        proxy_http_version 1.1;

        proxy_pass http://10.194.98.123:36099/ctm01expvideo-web/;

}

恢复正常。
