税务部门的一个公众号，已按照流程申请了人脸核身API权限。

前端正常唤起人脸识别组件，显示验证通过，后端调用人脸识别结果API【https://api.weixin.qq.com/cityservice/face/identify/getinfo】也正常返回了数据。

但接下来获取图片接口【https://api.weixin.qq.com/cityservice/face/identify/getimage】报错：{"errcode":48001,"errmsg":"api unauthorized hint: [KFY.eA0975d236][2020-05-30 11:39:35]"}

-------------------------------------模拟获取人像串的post请求-------------------：

curl --connect-timeout 3 -i -X POST -d 'verify_result=真实的verify_result' https://api.weixin.qq.com/cityservice/face/identify/getimage?access_token=真实的token

-----------------------------返回-----------------------------------
