建立云臉數據集的模塊:
#!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)
初始建立云聯數據集的模塊:
#!/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)
生成存儲facetoken:
這里從171860學號開始生成我的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()
