使用nginx反向代理，一个80端口下，配置多个微信项目

我们要接入微信公众号平台开发，需要填写服务器配置，然后依据接口文档才能实现业务逻辑。但是微信公众号接口只支持80接口（80端口）。我们因业务需求需要在一个公众号域名下面，发布两个需要微信授权的项目，怎么办？

　　我们可以用nginx服务器做反向代理来解决这个问题。nginx服务器对外80端口，然后根据URL参数不同，对内访问不同的项目。

　　

　　nginx配置如下：

　　打开/usr/local/nginx/conf/nginx.conf

 1 worker_processes  4; 2 error_log  logs/error.log; 3 events { 4     worker_connections  1024; 5 } 6 http { 7     include       mime.types; 8     default_type  application/octet-stream; 9     sendfile        on;10     keepalive_timeout  65;11 12 gzip on;13 gzip_min_length 1k;14 gzip_buffers 16 64k;15 gzip_http_version 1.1;16 gzip_comp_level 6;17 gzip_types text/plain application/x-javascript text/css application/xml application/javascript;18 gzip_vary on;19 20     #指向项目一21     upstream backend1  {22         server  192.168.1:8081;23     }24     #指向项目二25     upstream backend2{26         192.168.1.1:8082;27     }28     proxy_cache_path /tmp/cache levels=1:2 keys_zone=cache:128m inactive=1d  max_size=1G;29     include vhosts/*;30 }

　　打开/usr/local/reverse_proxy_nginx/conf/nginx.conf

 1 worker_processes  2; 2 events { 3     worker_connections  1024; 4 } 5 http { 6     include       mime.types; 7     default_type  application/octet-stream; 8     access_log  /home/nginx_log/reverse_proxy_no1_access.log; 9     sendfile        on;10     keepalive_timeout  65;11     upstream backend1  {12         #server 192.168.1.1:8181;13     server  192.168.1.1:8081;14     }15     upstream backend2  {16         #server 192.168.1.1:8082;17     server  192.168.1.1:8082;18     }19     proxy_cache_path /tmp/cache levels=1:2 keys_zone=cache:128m inactive=30m  max_size=1G;20     server {21         listen       8081;22         server_name  h5.xxxx.com;23 24         location / {25                 proxy_pass http://backend1;26             #Proxy Settings27                proxy_redirect     off;28              proxy_set_header   Host             $host;29             proxy_set_header   X-Real-IP        $remote_addr;30             proxy_set_header   X-Forwarded-For  $proxy_add_x_forwarded_for;31             proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;32             proxy_max_temp_file_size 0;33             proxy_connect_timeout      90;34             proxy_send_timeout         90;35             proxy_read_timeout         90;36             proxy_buffer_size          4k;37             proxy_buffers              4 32k;38             proxy_busy_buffers_size    64k;39             proxy_temp_file_write_size 64k;40         add_header Nginx-Res "http://backend1";41         }42 43         location ~ ^/(h5)(.*)$ { 44               proxy_pass  http://backend2;45               proxy_redirect off;46               proxy_set_header Host $host;47               proxy_cache cache;48               proxy_cache_valid 200 302 1d;49               proxy_cache_valid 301 1d;50               proxy_cache_valid any 1m;51               expires 1h;52           add_header Nginx-Res "http://backend2";53               proxy_ignore_headers "Cache-Control" "Expires" "Set-Cookie";54               add_header Nginx-Cache "$upstream_cache_status";55           }56 57         58         error_page   500 502 503 504  /50x.html;59         location = /50x.html {60             root   html;61         }62     location ~ .*\.(gif|jpg|png|css|js|ico)(.*) {63               proxy_pass http://backend1;64               proxy_redirect off;65               proxy_set_header Host $host;66               proxy_cache cache;67               proxy_cache_valid 200 302 30d;68               proxy_cache_valid 301 1d;69               proxy_cache_valid any 1m;70               expires 30d;71               proxy_ignore_headers "Cache-Control" "Expires" "Set-Cookie";72           add_header Nginx-Res "http://backend1";73               add_header Nginx-Cache "$upstream_cache_status";74         }

　　当我们打开URL包含h5时，就会跳到8081端口项目中，但是对外还是80端口。所以两个项目可以同时实现微信授权登录等。
