face++与python实现人脸识别签到（考勤）功能
项目实现利用face++开发一个课堂签到的软件，实现面向摄像头即可完成记录学号、姓名和时间的签到工作。

建立云脸数据集的模块：
#!usr/bin/
# -*- coding: utf-8 -*-
import requests
import time
from json import JSONDecoder
import csv
http_url ='https://api-cn.faceplusplus.com/facepp/v3/faceset/addface'
key = "z_qkMMqK1efq8ikgAPOEn89A7And-lAa"
secret = "***********************"
faceset_token = '******************************'
face_tokens_str = ''
csvfile = open('face_token.csv','r')
freader = csv.reader(csvfile)
facedata = []
i = 0
for item in freader:
i = i + 1
face_tokens_str = face_tokens_str + item[1] + ','
if i%5 == 0:
face_tokens_str = face_tokens_str[:-1]
facedata.append (face_tokens_str)
face_tokens_str = ''
face_tokens_str = face_tokens_str[:-1]
facedata.append (face_tokens_str)
csvfile.close()
for item in facedata:
print(item)
data = {"api_key":key,"api_secret":secret,"faceset_token":faceset_token,"face_tokens":item}
response = requests.post(http_url, data=data)
print(response)
print(response.text)
初始建立云联数据集的模块：
#!/usr/bin/env/ python
# _*_ coding:utf-8 _*_
import requests
from json import JSONDecoder
http_url = "https://api-cn.faceplusplus.com/facepp/v3/faceset/create"
get_url = "https://api-cn.faceplusplus.com/facepp/v3/faceset/getfacesets"
getdetails_url = "https://api-cn.faceplusplus.com/facepp/v3/faceset/getdetail"
key = "**********************"
secret = "*********************"
data = {"api_key":key,"api_secret":secret,"display_name":'SEUers',"outer_id":'zbpm'}
repn = requests.post(http_url,data = data)
print(repn)
print(repn.text)
data = {"api_key":key,"api_secret":secret}
repn = requests.post(get_url,data = data)
print(repn)
print(repn.text)
data = {"api_key":key,"api_secret":secret,"outer_id":'zbpm'}
repn = requests.post(getdetails_url,data = data)
print(repn)
print(repn.text)
生成存储facetoken：
这里从171860学号开始生成我的facetoken
#!usr/bin/
# -*- coding: utf-8 -*-
import requests
from json import JSONDecoder
import csv
id = 171860
http_url ='https://api-cn.faceplusplus.com/facepp/v3/detect'
key = "*******************"
secret = "*******************"
faceID_List = []
face_token_List = []
for i in range (0,10):
faceID = str(id + i)
file = "picture/"+ faceID + ".jpg"
data = {"api_key":key,"api_secret":secret,"return_landmark":1,}
file = {"image_file":open(file,'rb')}
response = requests.post(http_url,data = data,files = file)
req_con = response.content.decode('utf-8')
req_dict = JSONDecoder().decode(req_con)
face_token = req_dict["faces"][0]["face_token"]
faceID_List.append(faceID)
face_token_List.append(face_token)
print(faceID_List)
print(face_token_List)
csvfile = open('face_token.csv','a',newline = '')
fwriter = csv.writer(csvfile)
for i in range(len(faceID_List)):
fwriter.writerow([faceID_List[i],face_token_List[i]])
csvfile.close()
