更新时间:2021/05/28 GMT+08:00

功能介绍

查询当前用户所有人脸库的状态信息。

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

调试

您可以在API Explorer中调试该接口。

URI

GET /v2/{project_id}/face-sets

表1 路径参数

参数

是否必选

参数类型

描述

project_id

String

项目ID,获取方法请参见获取项目ID/账号名/AK/SK

请求参数

表2 请求Header参数

参数

是否必选

参数类型

描述

X-Auth-Token

String

用户Token。

Token认证就是在调用API的时候将Token加到请求消息头,从而通过身份认证,获得操作API的权限,响应消息头中X-Subject-Token的值即为Token。

响应参数

状态码:200

表3 响应Body参数

参数名

参数类型

说明

face_sets_info

List

人脸库信息集合,详见FaceSetInfo

调用失败时无此字段。

error_code

String

调用失败时的错误码,具体请参考错误码

调用成功时无此字段。

error_msg

String

调用失败时的错误信息。

调用成功时无此字段。

请求示例

X-Auth-Token值获取方法请参见认证鉴权

  • 请求样例
    GET https://{endpoint}/v2/{project_id}/face-sets
    Request Header:
    Content-Type: application/json
    X-Auth-Token: MIINRwYJKoZIhvcNAQcCoIINODCCDTQCAQExDT...
  • Python3语言请求代码示例(其他语言参照下列示例编写或使用FRS SDK)
    # -*- coding:utf-8 -*-
    
    import requests
    import base64
    
    endpoint = '开通服务所在region的人脸识别服务域名'
    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}
    
    url = "https://{endpoint}/v2/{project_id}/face-sets".format(endpoint=endpoint,project_id=project_id)
    response = requests.get(url, headers=headers, verify=False)
