使用百度账号登录百度AI平台,网址:http://ai.baidu.com/tech/face,
若没有直接注册一个账号。登录后需要点击“创建应用”填写命名一下,完成后返回,点击“管理应用”,就可以看到已经申请的[应用名称、AppID、API Key、Secret Key].
1.向授权服务地址:https://aip.baidubce.com/oauth/2.0/token?发送请求 并在此URL后带上以下参数:
· grant_type: 必须参数,固定为client_credentials;
· client_id: 必须参数,应用的API Key;
· client_secret: 必须参数,应用的Secret Key;
例如:你申请的API Key是Va5yQRHlA4Fq5eR30vV4,
Secret Key是0rDSjzQ20XUj5itV6WRtznPQSzr5pV,进行如下拼接:
https://aip.baidubce.com/oauth/2.0/token?grant_type=client_credentials&client_id=Va5yQRHlA4Fq5eR30vV4&client_secret=0rDSjzQ20XUj5itV6WRtznPQSzr5pV
此url 为向授权服务请求的完整地址,先命名为 api1
2,获取access_token的完整内容
response=requests.get(api1)
print( response)
# 打印结果如下:
{ "refresh_token": "25.b55fe1d287227ca97aab219bb249b8ab.315360000.1798284651.282335-8574074",

"session_secret": "dfac94a3489fe9fca7c3221cbf7525ff" }
# 我们需要其中的 access_token
3, 人脸匹配相似度的地址:“https://aip.baidubce.com/rest/2.0/face/v3/match”
# 2,获取token值,拼接API
import requests
def get_token():
response=requests.get(api1)
access_token=eval(response.text)['access_token'] #eval函数将字符串转化为字典
api2="https://aip.baidubce.com/rest/2.0/face/v3/match"+"?access_token="+access_token

])
return params`在这里插入代码片`

content=requests.post(api,params).text # 获取对比详细结果
print(content)
analyse_img("zly01.jpg","zly02.jpg"): # 找的两张 赵丽颖的照片
# 打印content内容如下:
{"error_code":0,"error_msg":"SUCCESS","log_id":1345050733350687141,"timestamp":1553335068,"cached":0,
"result":{"score":95.51683807,"face_list",[{"face_token":"938e0c197a7f53d9eced7551c6cd6c50"},{"face_token":"81ab41769b6fc5877d944415e380e326"}]}}
# 我们需要的是"score":95.51683807",相似度95.5,可以确认是同一个人。
找的图片:赵丽颖2张(zly01.jpg,zly02.jpg),刘亦菲一张(lyf01.jpg)
