　　 include /home/xxx/opt/nginx/conf.d/mime.types;

MIME-type和Content-Type的关系：
当web服务器收到静态的资源文件请求时，依据请求文件的后缀名在服务器的MIME配置文件中找到对应的MIME Type，再根据MIME Type设置HTTP Response的Content-Type，然后浏览器根据Content-Type的值处理文件。

types {
    Content-Type                          文件名后缀

　　参考：nginx proxy_pass和rewrite的区别      Nginx之proxy_redirect详解　　

location基本配置

 location /A/B{
          proxy_pass  http://XXX.com/A/B;#请求转向定义的服务器列表
          #proxy_redirect off;
          proxy_set_header Host XXX.com;
          proxy_set_header X-Real-IP $remote_addr;
          proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
          client_max_body_size 10m;    #允许客户端请求的最大单文件字节数
          client_body_buffer_size 128k;  #缓冲区代理缓冲用户端请求的最大字节数，
          proxy_connect_timeout 180;  #nginx跟后端服务器连接超时时间(代理连接超时)
          proxy_send_timeout 180;        #后端服务器数据回传时间(代理发送超时)
          proxy_read_timeout 180;         #连接成功后，后端服务器响应时间(代理接收超时)
          proxy_buffer_size 128k;             #设置代理服务器（nginx）保存用户头信息的缓冲区大小
          proxy_buffers 4 256k;               #proxy_buffers缓冲区，网页平均在32k以下的话，这样设置
          proxy_busy_buffers_size 512k;    #高负荷下缓冲大小（proxy_buffers*2）
          proxy_temp_file_write_size 512k;  #设定缓存文件夹大小，大于这个值，将从upstream服务器传
    }

 

       参考：微信网页授权流程 

nginx配置域名转发

　　场景：有两个微信公众号A、B，微信公众号管理平台配置的回调url分别是 http://A.com、http://B.com。微信公众号B如果需要获取微信公众号A的用户信息，对应的授权URL如下。

https://open.weixin.qq.com/connect/oauth2/authorize?appid=wx43a850f87498127d&redirect_uri=http%3A%2F%2FA.com%2F&response_type=code&scope=snsapi_userinfo&state=STATE#wechat_redirect

 

这样就会面临一个问题，微信公众号B就无法获取到code信息了。

腾讯返回的授权码URL:    http://A.com/?code=001Rk8ue1Ntnxz0udwue1kbUte1Rk8uU&state=STATE

 

所以需要微信公众号A对应的Nginx做一下域名转发，如下。

微信公众号A对应的Nginx配置（实现域名转发，将微信公众号A对应的域名转发成微信公众号B对应的域名）

location /微信公众号B标识/XXX {
                rewrite ^/微信公众号B标识/(.*) http://B.com/$1 permanent;
                proxy_set_header Host B.com;
                proxy_set_header X-Real-IP $remote_addr;
                proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
                client_max_body_size 20m;
                client_body_buffer_size 128k;
                proxy_connect_timeout 90;
                proxy_send_timeout 90;
                proxy_read_timeout 90;
                proxy_buffer_size 4k;
                proxy_buffers 4 32k;
                proxy_busy_buffers_size 64K;
                proxy_temp_file_write_size 64k;
        }

　　上面的方案是基于永久重定向，浏览器的URL会发生变化。

　　另一种方案是基于nginx代理的，但是需要公众号A、B使用同一个域名。这种方案也支持自定义链接分享【如果两个公众号使用不同的域名，自定义链接分享必然出现无效的签名这种问题】。

location /微信公众号B标识/XXX {
     proxy_pass  http://B.com/微信公众号B标识/XXX/YYY;
     proxy_redirect off;
     proxy_set_header Host B.com;
     proxy_ignore_client_abort on;
     proxy_set_header X-Real-IP $remote_addr;
     proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
     client_max_body_size 10m;
     client_body_buffer_size 128k;
     proxy_connect_timeout 8;
     proxy_send_timeout 1800;
     proxy_read_timeout 1800;
     proxy_buffer_size 128k;
     proxy_buffers 4 256k;
     proxy_busy_buffers_size 512k;
     proxy_temp_file_write_size 512k;
}
