Nginx反向代理一个80端口下配置多个微信项目详解

　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

worker_processes 4;
error_log logs/error.log;
events {
worker_connections 1024;
}
http {
include    mime.types;
default_type application/octet-stream;
sendfile    on;
keepalive_timeout 65;
gzip on;
gzip_min_length 1k;
gzip_buffers 16 64k;
gzip_http_version 1.1;
gzip_comp_level 6;
gzip_types text/plain application/x-javascript text/css application/xml application/javascript;
gzip_vary on;
#指向项目一
upstream backend1 {
server 192.168.1:8081;
}
#指向项目二
upstream backend2{
192.168.1.1:8082;
}
proxy_cache_path /tmp/cache levels=1:2 keys_zone=cache:128m inactive=1d max_size=1G;
include vhosts/*;
}

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

worker_processes 2;
events {
worker_connections 1024;
}
http {
include    mime.types;
default_type application/octet-stream;
access_log /home/nginx_log/reverse_proxy_no1_access.log;
sendfile    on;
keepalive_timeout 65;
upstream backend1 {
#server 192.168.1.1:8181;
server 192.168.1.1:8081;
}
upstream backend2 {
#server 192.168.1.1:8082;
server 192.168.1.1:8082;
}
proxy_cache_path /tmp/cache levels=1:2 keys_zone=cache:128m inactive=30m max_size=1G;
server {
listen    8081;
server_name h5.xxxx.com;
location / {
proxy_pass http://backend1;
#Proxy Settings
proxy_redirect   off;
proxy_set_header  Host       $host;
proxy_set_header  X-Real-IP    $remote_addr;
proxy_set_header  X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_next_upstream error timeout invalid_header http_500 http_502 http_503 http_504;
proxy_max_temp_file_size 0;
proxy_connect_timeout   90;
proxy_send_timeout     90;
proxy_read_timeout     90;
proxy_buffer_size     4k;
proxy_buffers       4 32k;
proxy_busy_buffers_size  64k;
proxy_temp_file_write_size 64k;
add_header Nginx-Res "http://backend1";
}
location ~ ^/(h5)(.*)$ {
proxy_pass http://backend2;
proxy_redirect off;
proxy_set_header Host $host;
proxy_cache cache;
proxy_cache_valid 200 302 1d;
proxy_cache_valid 301 1d;
proxy_cache_valid any 1m;
expires 1h;
add_header Nginx-Res "http://backend2";
proxy_ignore_headers "Cache-Control" "Expires" "Set-Cookie";
add_header Nginx-Cache "$upstream_cache_status";
}
error_page  500 502 503 504 /50x.html;
location = /50x.html {
root  html;
}
location ~ .*\.(gif|jpg|png|css|js|ico)(.*) {
proxy_pass http://backend1;
proxy_redirect off;
proxy_set_header Host $host;
proxy_cache cache;
proxy_cache_valid 200 302 30d;
proxy_cache_valid 301 1d;
proxy_cache_valid any 1m;
expires 30d;
proxy_ignore_headers "Cache-Control" "Expires" "Set-Cookie";
add_header Nginx-Res "http://backend1";
add_header Nginx-Cache "$upstream_cache_status";
}

　　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。
