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 requestsimport timefrom json import JSONDecoderimport 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 = 0for 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 requestsfrom 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 requestsfrom json import JSONDecoderimport 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()
