使用BASE64方式进行人脸检测
使用BASE64方式上传本地照片进行人脸检测，关键代码如下。
""" 选择BASE64 """
filePath ="pic.png"
with open(filePath,"rb") as f:
b64encode是编码
base64_data = base64.b64encode(f.read())
image = str(base64_data,'utf-8')
imageType = "BASE64"
""" 调用人脸检测 """
client.detect(image, imageType)
""" 如果有可选参数 """
options = {}
options["face_field"] = "age,beauty"
options["max_face_num"] = 1
options["face_type"] = "LIVE"
""" 带参数调用人脸检测 """
print (client.detect(image, imageType, options))
