websocket wss所需的nginx配置以及解決golang做爲服務端的跨域問題

 下面的配置是微信小程序所需的wss的配置,這裏爲了方便,,也爲了不使用端口號,和原項目的配置寫在一塊兒了,所以使用了固定後綴/wss,以做區分,配置的重點就是location /wss 段,其以後的部分是原項目所需的配置.

upstream websocket {
    server 127.0.0.1:12121;
}

server{
    listen 443;
    server_name ___aaa___.com;
    index index.html index.htm index.php default.html default.htm default.php;
    root  /___aaa___;

    #include none.conf;
    #error_page   404   /404.html;
    include enable-php-pathinfo.conf;
		
	ssl on;
    ssl_certificate   /___aaa___.pem;
    ssl_certificate_key  /___aaa___.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;

    # 用於小程序的 websocket 鏈接
    location /wss {
        proxy_pass http://websocket;#代理到上面的地址去
        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "Upgrade";
    }

    location / {   
        # 主項目
    } 

    location ~ .*\.(gif|jpg|jpeg|png|bmp|swf)$
    {
        expires      30d;
    }

    location ~ .*\.(js|css)?$
    {
        expires      12h;
    }

    location ~ /\.
    {
        deny all;
    }

    access_log  /___aaa___.log;
}

服務端使用 golang的話,若是使用的  github.com/gorilla/websocket ,須要添加如下配置

var upgrader = websocket.Upgrader{
	// 解決跨域問題
	CheckOrigin: func(r *http.Request) bool {
		return true
	},
}
