工程中的nginx配置

nginx配置详解参考：Nginx配置文件（nginx.conf）配置详解
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 text/html html htm shtml; text/css css; text/xml xml; image/gif gif; image/jpeg jpeg jpg; application/javascript js; application/atom+xml atom; application/rss+xml rss; text/mathml mml; text/plain txt; text/vnd.sun.j2me.app-descriptor jad; text/vnd.wap.wml wml; text/x-component htc; image/png png; image/tiff tif tiff; image/vnd.wap.wbmp wbmp; image/x-icon ico; image/x-jng jng; image/x-ms-bmp bmp; image/svg+xml svg svgz; image/webp webp; application/font-woff woff; application/java-archive jar war ear; application/json json; application/mac-binhex40 hqx; application/msword doc; application/pdf pdf; application/postscript ps eps ai; application/rtf rtf; application/vnd.apple.mpegurl m3u8; application/vnd.ms-excel xls; application/vnd.ms-fontobject eot; application/vnd.ms-powerpoint ppt; application/vnd.wap.wmlc wmlc; application/vnd.google-earth.kml+xml kml; application/vnd.google-earth.kmz kmz; application/x-7z-compressed 7z; application/x-cocoa cco; application/x-java-archive-diff jardiff; application/x-java-jnlp-file jnlp; application/x-makeself run; application/x-perl pl pm; application/x-pilot prc pdb; application/x-rar-compressed rar; application/x-redhat-package-manager rpm; application/x-sea sea; application/x-shockwave-flash swf; application/x-stuffit sit; application/x-tcl tcl tk; application/x-x509-ca-cert der pem crt; application/x-xpinstall xpi; application/xhtml+xml xhtml; application/xspf+xml xspf; application/zip zip; application/octet-stream bin exe dll; application/octet-stream deb; application/octet-stream dmg; application/octet-stream iso img; application/octet-stream msi msp msm; application/vnd.openxmlformats-officedocument.wordprocessingml.document docx; application/vnd.openxmlformats-officedocument.spreadsheetml.sheet xlsx; application/vnd.openxmlformats-officedocument.presentationml.presentation pptx; audio/midi mid midi kar; audio/mpeg mp3; audio/ogg ogg; audio/x-m4a m4a; audio/x-realaudio ra; video/3gpp 3gpp 3gp; video/mp2t ts; video/mp4 mp4; video/mpeg mpeg mpg; video/quicktime mov; video/webm webm; video/x-flv flv; video/x-m4v m4v; video/x-mng mng; video/x-ms-asf asx asf; video/x-ms-wmv wmv; video/x-msvideo avi; }

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; }
