菜鸟求问一个最最基本的 Python request 问题

from urllib.request import Request, urlopen
import json
from config import appcode

host = 'http://wbzy.market.alicloudapi.com'
path = '/rest/160601/text_analysis/attention_text_summary.json'
url = host + path

def attention_text_summary(data):
body1 = "{\"inputs\":[{\"text\":{\"dataType\":50,\"dataValue\":\""
body2 = "\"}}]}"
outputs = json.loads(get_response(body1, data, body2, url, appcode))
dataValue = json.loads(outputs["outputs"][0]["outputValue"]["dataValue"])
return dataValue["summary"]

def get_response(body1, data, body2, url, appcode):
bodys = {}
bodys[''] = body1 + data + body2
post_data = bodys[''].encode('utf8')
request = Request(url, data=post_data)
#request = urllib.request.Request(url, post_data)
request.add_header('Authorization', 'APPCODE ' + appcode)
# 根据 API 的要求，定义相对应的 Content - Type
request.add_header('Content-Type', 'application/json; charset=UTF-8')
response = urlopen(request)
return response.read().decode("utf-8")

def main():
data = "副省长、省食安委副主任看望慰问一线人感染 H7N9 禽流感防控工作人员。"
dataanys = attention_text_summary(data)
print(type(dataanys))
print(len(dataanys))

print(dataanys)

if __name__ == '__main__':
main()

因为导师的需要，需要调用阿里云的文本分析工具，编程我真是菜的一 B，运行这段代码得到

实在看不出哪里有错了，请各位大佬赐教

问题解决。。按一楼大佬的办法重新用了 requests 发现新世界
阿里云的示例是用 urllib 写的。。真是绕了很大的弯子

# -*- coding: UTF-8 -*-
import requests
import json

host = ''
path = ''
url = host+path
appcode = ""
body = {
"inputs": [
{
"text": {
"dataType": 50,
"dataValue": "“像家一样”,这样的酒店宣传语估计要大打折扣了,理由就是——脏!日前,加拿大一项堪称最大规模的调查显示,包括速 8、喜来登以及假日酒店在内的 6 大连锁酒店用品,如床上用品、遥控器等都有细菌,威胁住客健康,希望连锁酒店给住客一个真正干净的“家”"
}
}
]
}
headers = {
'Authorization':'APPCODE ' +appcode,
'Content-Type':'application/json; charset=UTF-8'
}
r = requests.post(url, data=json.dumps(body), headers=headers)
text = json.loads(r.text)
print(type(text))
