调用方法

POST

权限

所有 API Key 都可以调用本 API。

请求参数

是否必选

参数名

类型

参数说明

必选

api_key

String

调用此 API 的 API Key

必选

api_secret

String

调用此 API 的 API Secret

必选

face_tokens

String

一个字符串，由一个或多个人脸标识组成，用逗号分隔。最多支持 5 个 face_token。

必选（至少使用一项）

return_landmark

Int

是否检测并返回人脸关键点。合法值为：

2	检测。返回 106 个人脸关键点。
1	检测。返回 83 个人脸关键点。
0	不检测

注：本参数默认值为 0

return_attributes

String

是否检测并返回根据人脸特征判断出的年龄、性别、情绪等属性。合法值为：

none

不检测属性

gender
age
smiling
headpose
facequality
blur
eyestatus
emotion
ethnicity
beauty
mouthstatus
eyegaze
skinstatus

希望检测并返回的属性。

需要将属性组成一个用逗号分隔的字符串，属性之间的顺序没有要求。

关于各属性的详细描述，参见下文“返回值”说明的 "attributes" 部分。

注：由于提供了 eyestatus，所以 glass 参数将被移除（计划时间 2017-9-30），请尽快修改程序使用 eyestatus

注：本参数默认值为 none

返回值说明

字段	类型	说明
request_id	String	用于区分每一次请求的唯一的字符串。
faces	Array	经过分析的人脸数组注：如果没有检测出人脸则为空数组
time_used	Int	整个请求所花费的时间，单位为毫秒。
error_message	String	当请求失败时才会返回此字符串，具体返回内容见后续错误信息章节。否则此字段不存在。

faces 数组中单个元素的结构

字段	类型	说明
face_token	String	人脸的标识
face_rectangle	Object	人脸矩形框的位置，包括以下属性。每个属性的值都是整数： top：矩形框左上角像素点的纵坐标 left：矩形框左上角像素点的横坐标 width：矩形框的宽度 height：矩形框的高度
landmark	Object	人脸的关键点坐标数组。当传入的 landmark 参数值为 1 时，返回 83 个关键点坐标数组。当传入的 landmark 参数值为 2 时，返回 106 个关键点坐标数组。关于 83 个或 106 个关键点坐标的详细说明与图示，请分别参考文档：《人脸关键点 Landmark 说明（83 点）》、《人脸关键点 Landmark 说明（106 点）》
attributes	Object	人脸属性特征，具体包含的信息见下表。

attributes 中包含的元素说明

skinstatus

Object

面部特征识别结果，包括以下字段。每个字段的值都是一个浮点数，范围 [0,100]，小数点后 3 位有效数字。每个字段的返回值越大，则该字段代表的状态的置信度越高。

health：健康
stain：色斑
acne：青春痘
dark_circle：黑眼圈

注意：faces_token的读取

data["faces"][0]["face_token"],

json.loads()用于将str类型的数据转成dict。取出faces里面的faces_token,注意不是result里面的faces_token；
