Nginx反向代理一個(gè)80端口下配置多個(gè)微信項(xiàng)目詳解

　我們要接入微信公眾號(hào)平臺(tái)開發(fā)，需要填寫服務(wù)器配置，然后依據(jù)接口文檔才能實(shí)現(xiàn)業(yè)務(wù)邏輯。但是微信公眾號(hào)接口只支持80接口（80端口）。我們因業(yè)務(wù)需求需要在一個(gè)公眾號(hào)域名下面，發(fā)布兩個(gè)需要微信授權(quán)的項(xiàng)目，怎么辦？

　　我們可以用nginx服務(wù)器做反向代理來解決這個(gè)問題。nginx服務(wù)器對(duì)外80端口，然后根據(jù)URL參數(shù)不同，對(duì)內(nèi)訪問不同的項(xiàng)目。

　　nginx配置如下：

　　打開/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;  #指向項(xiàng)目一  upstream backend1 {    server 192.168.1:8081;  }  #指向項(xiàng)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/*;}

　　打開/usr/local/reverse_proxy_nginx/conf/nginx.conf
