功能实现

#!/usr/bin/env python
#coding=utf-8

from aliyunsdkcore.client import AcsClient
from aliyunsdkcore.acs_exception.exceptions import ClientException
from aliyunsdkcore.acs_exception.exceptions import ServerException
from aliyunsdkfacebody.request.v20191230.RecognizeExpressionRequest import RecognizeExpressionRequest

client = AcsClient('<accessKeyId>', '<accessSecret>', 'cn-shanghai')

request = RecognizeExpressionRequest()
request.set_accept_format('json')

request.set_ImageURL("https://current-cloud-oss.oss-cn-shanghai.aliyuncs.com/pic/20.jpg")

response = client.do_action_with_exception(request)
# python2:  print(response) 
print(str(response, encoding='utf-8'))
