微信第三方平台定时接收component_verify_ticket，第三方平台ticket推送

背景：

      获取第三方平台令牌（component_access_token），增加了component_verify_ticket参数。component_verify_ticket由公众平台每隔10分钟，持续推送给第三方平台方（在创建公众号第三方平台审核通过后，才会开始推送）。

 

目标：

      接收微信服务器推送的component_verify_ticket

 

文档说明：（参见微信开放平台文档）

      推送component_verify_ticket协议

      在公众号第三方平台创建审核通过后，微信服务器会向其“授权事件接收URL”每隔10分钟定时推送component_verify_ticket。第三方平台方在收到ticket推送后也需进行解密（详细请见【消息加解密接入指引】），接收到后必须直接返回字符串success。

      于是在开放平台管理中心中寻找“授权事件接收URL”，如下图。

      

 

截获微信推送component_verify_ticket的POST请求地址：

      http://[授权事件接收URL]?encrypt_type=aes
          ×tamp=1438521627
          &nonce=33431792
          &msg_signature=xxxxxx
          &signature=xxxxxxx

请求内容格式:

       
         
         
     

 

知晓了微信推送xml的格式，接下来要做的就是解密xml，于是继续阅读文档，（参见 微信开放平台 消息加解密指引）

关于解密，微信公众平台提供了c++, php, java, python, c# 5种语言的示例代码（点击下载）

 

这里基于php版本的示例代码来实现PHP接收component_verify_ticket（基于CI框架）
