python3使用requests访问asp页面时出错，返回500

Question

学校的官微有个一键查成绩的功能，我一直很想能做出来玩，现在在学习python，正好准备拿来练手，但是访问的时候却出现了500错误。

以下是代码：
python

import requests
import time
import hashlib
from user import user

url1 = 'http://202.115.133.173:805/Common/Handler/UserLogin.ashx'
url2 = 'http://202.115.133.173:805/Default.aspx'
url3 = 'http://202.115.133.173:805/MyMessage/MyMsgForm.aspx'
username = user.name
password = user.pwd
sign = int(time.time()*1000)
headers = {

'Accept': 'text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8',
'Accept-Encoding': 'gzip, deflate, compress',
'Accept-Language': 'en-us;q=0.5,en;q=0.3',
'Cache-Control': 'max-age=0',
'Connection': 'keep-alive',
'Host':'202.115.133.173:805',
'Referer':'',
'Upgrade-Insecure-Requests':'1',
'User-Agent': 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:22.0) Gecko/20100101 Firefox/22.0'

}

def treatpwd(user, sign, pwd):

pwdmd5 = hashlib.md5()
pwdmd5.update(pwd.encode("utf-8"))
loginpwd = pwdmd5.hexdigest()
return loginpwd

datas = {

'Action':'Login',
'userName':username,
'pwd':treatpwd(username, sign, password),
'sign':sign,

}

if name == "__main__":

req = requests.Session()
headers['Referer'] = url1
print(headers)
req.headers.update(headers)

resp1 = req.post(url1,data=datas)
print(resp1)
headers['Referer'] = url1
print(headers)
req.headers.update(headers)
print(req.headers)

resp2 = req.get(url2)
print(resp2.headers)
headers['Referer'] = url2
req.headers.update(headers)

resp3 = req.get(url3)
print(resp3.headers)
print(resp3)

我在网上查询了之后，发现可能是refer的问题，但是更新refer的时候又出了问题。

以下是输出信息：

现在感觉有点晕，不知道应该怎么做了。
顺带一提：我输出登陆成功后的respons的源码时，发现也是不对，说明在登陆成功的页面就出了问题。

你应该提供一个测试帐号，不然谁能帮你？
