功能介绍

删除人脸库以及其中所有的人脸。人脸库数据为用户隐私数据，该数据无备份，删除时请谨慎操作。V1版本接口已经停售，该接口仅老用户可用，新用户推荐使用V2版本API。

前提条件：

请确保您已开通人脸识别服务，具体操作方法请参见申请服务。

  project_id = '开通服务所在region的用户项目ID'
  token = '用户获取得到的实际token值'
  headers = {'Content-Type': 'application/json', 'X-Auth-Token': token}
  
  face_set_name = 'showFaceSet'
  url = "https://{endpoint}/v1/{project_id}/face-sets/{face_set_name}".format(endpoint=endpoint,project_id=project_id,face_set_name=face_set_name)
  response = requests.delete(url, headers=headers, verify=False)
  print(response.text)
