nginx如何同时配置https和wss？

nginx同时配置https和wss代码如下：

server {

listen 443 ssl;

server_name localhost;

ssl on;

root html;

index index.html index.htm;

ssl_certificate   ******.pem;

ssl_certificate_key  *******.key;

ssl_session_timeout 5m;

ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;

ssl_protocols TLSv1 TLSv1.1 TLSv1.2;

ssl_prefer_server_ciphers on;

location /{

proxy_pass   https://localhost:3001;

}

location /ws {

proxy_pass https://localhost:8181; 

proxy_read_timeout 60s;

proxy_http_version 1.1;

proxy_set_header Upgrade $http_upgrade;

proxy_set_header Connection 'Upgrade';

}   

}

WebSocket协议的握手和HTTP是兼容的，它使用HTTP的Upgrade协议头将连接从HTTP连接升级到WebSocket连接。这个特性使得WebSocket应用程序可以很容易地应用到现有的基础设施。就可以使用https//+域名访问和使用wss://+域名＋/ws访问了
