微信公众号消息与事件处理机制

一：授权事件接收URL

1：微信服务器每隔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

{ComponentVerifyTicket=ticket@@@fxUU8P4_ip5B-S1sBL2SHmfA24haZRIUR8QIs0jLRXNfg1iBm4Lmv_h3T6Pb3KoXhNm-MspBFXr1cpN7nMzWDA,
CreateTime=1453311619,
AppId=wx630d7795f554888e,
InfoType=component_verify_ticket}

将ticket存储到redis缓存中备用。（获取component_access_token的时候会用到）

2：取消授权：

{CreateTime=1456983869,AppId=wx630d7795f554888e,AuthorizerAppid=wx136a04a96a5a4315,InfoType=unauthorized}

update公众号的授权状态status = 0（微信公众号一件授权绑定的时候，设置状态status = 1）
