python調用Face++，玩壞了！

看到一句話，如果你寫代碼沒有寫詩一樣的感覺，那你不适合做程式猿！

還是直接上代碼吧：

import requests
from json import JSONDecoder
import cv2
import os

http_url ="https://api-cn.faceplusplus.com/facepp/v3/detect"
# your key and your secret，急用的話，可以加微信lp9628。
key ="***"
secret ="***"    


filename = '/Users/liupeng/Desktop/anaconda/widerface/WIDER_train/images'
for filename1 in os.listdir(filename):
    print filename1
    if (filename1[0] != '.'):
        filename1 = filename + '/' + filename1
        for filename2 in os.listdir(filename1):
            print filename2 
            if (filename2[0] != '.'):
                filename2 = filename1 + '/' + filename2
                
                filepath = filename2
                data = {"api_key":key, "api_secret":secret, "return_landmark":"1"}
                files = {"image_file":open(filepath, "rb")}
                response = requests.post(http_url, data=data, files=files)
                req_con = response.content.decode('utf-8')
                req_dict = JSONDecoder().decode(req_con)
                print (len(req_dict[u'faces']))
                
                face_num = len(req_dict[u'faces'])
                frame = cv2.imread(filepath)
                for i in range(face_num):
                    box = req_dict[u'faces'][i][u'face_rectangle']
                    print(box)
                    x, y, w, h = box[u'left'], box[u'top'],box[u'width'],box[u'height']
                    color = (0, 255, 0)
                    cv2.rectangle(frame, (x, y), (x + w, y + h), color, 2)
                #顯示圖像
                cv2.imshow("faceDetecion", frame)        
                c = cv2.waitKey(10)
cv2.destroyAllWindows()
