参考的如上文档，还是报错了

https://api.weixin.qq.com/sns/oauth2/component/access_token?component_appid=wx8cc859a29f223a**&grant_type=authorization_code&code=05107IFa1ebBdG0aaQHa13SBYr407IFI&component_access_token=*****&appid=wxea93cf18eabd****

注：component_access_token字段是从如下接口获取的：https://api.weixin.qq.com/sns/oauth2/component/access_token

返回结果如下

{

"errcode": 48001,

"errmsg": "api unauthorized, rid: 652e6bbb-7d234df1-67f3f57c"

}
