使用nginx反向 Proxy，一個80連接埠下，配置多個微信項目，nginx80

使用nginx反向 Proxy，一個80連接埠下，配置多重專案，nginx80

　　我們要接入公眾號平台開發，需要填寫伺服器配置，然後依據介面文檔才能實現商務邏輯。但是公眾號介面只支援80介面（80連接埠）。我們因業務需求需要在一個公眾號網域名稱下面，發布兩個需要授權的項目，怎麼辦？

　　我們可以用nginx伺服器做反向 Proxy來解決這個問題。nginx伺服器對外80連接埠，然後根據URL參數不同，對內訪問不同的項目。

　　

　　nginx配置如下：

　　開啟/usr/local/nginx/conf/nginx.conf

　　開啟/usr/local/reverse_proxy_nginx/conf/nginx.conf

　　當我們開啟URL包含h5時，就會跳到8081連接埠項目中，但是對外還是80連接埠。所以兩個項目可以同時實現授權登入等。
