这个是百度人脸识别api
调用主要有三步：
获取access_token
将图片处理成base64编码格式
post请求访问接口得到结果
1.获取access_token
官方给的python示例代码，不过这个是python2的代码，python3里已经没有了urllib2，而且很繁琐
给出博主自己编写的py3利用requests的demo:
# -*- coding: utf-8 -*-
__author__ = 'fff_zrx'
import requests
#获取access_token
#client_id 为官网获取的AK， client_secret 为官网获取的SK
host = '/oauth/2.0/token?grant_type=client_credentials&client_id=your ak&client_secret=your sk'
header={'Content-Type': 'application/json; charset=UTF-8'}
response1=requests.post(url=host,headers=header)#
json1 = response1.json()#
access_token=json1['access_token']
2.将图片处理成base64编码格式
流程大致是将图片读取为二进制格式，再利用二进制到base64格式的函数转换
参考博客
图片来自here
转换代码：
import base64
filepath='zrx.jpg'
f = open(r'%s' % filepath, 'rb')
pic = base64.b64encode(f.read())
f.close()
base64=str(pic,'utf-8')
print(base64)
3.post请求访问接口得到结果
request_url = "/rest/2.0/face/v3/detect"
params = {"image":base64,"image_type":"BASE64","face_field":"faceshape,facetype,beauty,"}
header={'Content-Type': 'application/json'}
request_url = request_url + "?access_token=" + access_token
response1=requests.post(url=request_url,data=params,headers=header)#
json1 = response1.json()#
print(json1)
print("颜值评分为")
print (json1["result"]["face_list"][0]['beauty'],'分/100分')
完整代码：
# -*- coding: utf-8 -*-

import base64
#获取access_token
#client_id 为官网获取的AK， client_secret 为官网获取的SK
host = '/oauth/2.0/token?grant_type=client_credentials&client_id=your ak&client_secret=your sk'
header={'Content-Type': 'application/json; charset=UTF-8'}
response1=requests.post(url=host,headers=header)#
json1 = response1.json()#
access_token=json1['access_token']
#转换图片格式
filepath='zrx.jpg'
f = open(r'%s' % filepath, 'rb')
pic = base64.b64encode(f.read())
f.close()
base64=str(pic,'utf-8')
print(base64)
#访问人脸检测api
request_url = "/rest/2.0/face/v3/detect"
params = {"image":base64,"image_type":"BASE64","face_field":"faceshape,facetype,beauty,"}
header={'Content-Type': 'application/json'}
request_url = request_url + "?access_token=" + access_token
response1=requests.post(url=request_url,data=params,headers=header)#
json1 = response1.json()#
print(json1)
print("颜值评分为")
print (json1["result"]["face_list"][0]['beauty'],'分/100分')
