微信小程序wss地址不允許使用端口，于是就利用nginx轉發(fā)。

1、nginx版本是需要大于1.3
2、nginx配置文件修改

upstream websocket { 
    server ip:端口;  //轉發(fā)
}
server {
        listen 443;
        server_name 域名;
        ssl on;
        ssl_certificate   證書;
        ssl_certificate_key 證書;
        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 /wss {
             access_log /usr/share/nginx/logs/https-websocket.log;
             proxy_pass http://websocket/; # 代理到上面
             proxy_set_header X-Real-IP $remote_addr;
             proxy_set_header Host $host;
             proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
             proxy_http_version 1.1;
             proxy_set_header Upgrade $http_upgrade;
             proxy_set_header Connection "upgrade";
             rewrite /wss/(.*) /$1 break;
             proxy_redirect off;
        } 
}

3、GatewayWorker下的修改，用了nginx就不需要在此處使用ssl了，文檔有提到 https://www.kancloud.cn/walkor/workerman/315297

$gateway = new Gateway("websocket://0.0.0.0:9993");

4、小程序那直接使用這個url : wss://域名/wss
