开始对于component_verify_ticket这个参数我一直没弄明白,所以使用这种post请求方式获取第三方平台的access_token就没能成功。
经过仔细阅读文档后解决了这一问题:
----------------------------------------------------------------------官方文档---开始---------------------------------------------------------------
8、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。
POST数据示例
<xml>
<AppId> </AppId>
<CreateTime>1413192605 </CreateTime>
<InfoType> </InfoType>
<ComponentVerifyTicket> </ComponentVerifyTicket>
</xml>
字段说明
字段名称 | 字段描述 |
---|---|
Appid | 第三方平台appid |
CreateTime | 时间戳 |
InfoType | component_verify_ticket |
ComponentVerifyTicket | Ticket内容 |
