nginx配置websocket wss前缀访问

Nginx 从 1.3 版本开始支持 WebSocket ，并且可以为 WebSocket 应用程序做反向代理和负载均衡。

在https 配置 SSL证书的localhost下面，新增一个localhost，里面写websocket的配置，如果配置了反向代理，就不需要加端口号去访问

map $http_upgrade $connection_upgrade {
        default upgrade;
        ''      close;
    }


server {
        listen       443;
