流程代码，主文件

#!usr/bin/# -*- coding: utf-8 -*-import requestsfrom json import JSONDecoderimport csvimport cv2import timeimport tkinter as tk search_url = "https://api-cn.faceplusplus.com/facepp/v3/search"getdetail_url = "https://api-cn.faceplusplus.com/facepp/v3/faceset/getdetail"key = "***************"secret = "*********************" filename = time.time()filepath = "photo/" + str(filename) + ".jpg" cap = cv2.VideoCapture(0)while(1):  # get a frame  ret, frame = cap.read()  # show a frame  cv2.imshow("capture", frame)  if cv2.waitKey(1) & 0xFF == ord('1'):    cv2.imwrite(filepath, frame)    breakcap.release()cv2.destroyAllWindows() print("waiting...") csvfile = open('face_token.csv','r')freader = csv.reader(csvfile)dic = dict(freader)csvfile.close()faceID_dict = {v:k for k,v in dic.items()}print("...") data = {"api_key": key, "api_secret": secret, "outer_id":'zbpm'}files = {"image_file": open(filepath, "rb")}response = requests.post(search_url, data=data, files=files)req_con = response.content.decode('utf-8')req_dict = JSONDecoder().decode(req_con)pre_face_token = req_dict["results"][0]["face_token"]pre_confidence = req_dict["results"][0]["confidence"]pre_thresholds = req_dict["thresholds"]["1e-5"]print("...") data = {"api_key": key, "api_secret": secret,"outer_id":'zbpm'}response = requests.post(getdetail_url, data=data)req_con = response.content.decode('utf-8')req_dict = JSONDecoder().decode(req_con)faces_token = req_dict["face_tokens"]print("...") if pre_face_token in faces_token and pre_confidence >= pre_thresholds:  labaltext = faceID_dict[pre_face_token] + "\n\n\n" +str(time.asctime(time.localtime()))  window = tk.Tk()  window.title = ('FaceID')  window.geometry = ('200x200')  var = tk.StringVar()   l = tk.Label(window,bg = 'yellow',text = labaltext,font=("黑体",20 ,"bold"),width = 30,height = 20)  l.pack()  l.config(text=labaltext+var.get())  #tk.messagebox.askokcancel('faceId', faceID_dict[pre_face_token] + "\n" +str(time.asctime(time.localtime())))  print(faceID_dict[pre_face_token])else:  tkinter.messagebox.askokcancel('提示', '未找到')  print("未找到")

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()
