my_headers={

sss=requests.session()
r=sss.get(url,headers=my_headers)
reg=r'<input type="hidden" name="__VIEWSTATE" id="__VIEWSTATE" value="(.*)" />'
pattern = re.compile(reg)
result  = pattern.findall(r.content)
viewstate   = result[0]

reg=r'<input type="hidden" name="__EVENTVALIDATION" id="__EVENTVALIDATION" value="(.*)" />'
pattern = re.compile(reg)
result  = pattern.findall(r.content)
eventvalidation=result[0]

my_data={'__EVENTTARGET':'',
'__EVENTARGUMENT':'',
'__VIEWSTATE':viewstate,
'__VIEWSTATEGENERATOR':'EC620E5A',
'__PREVIOUSPAGE':'cMlf7B-ve9HBkgfrfv-q8AJ50_VEsc0av7p79gkEJJkZqg6TfVcScwYFuXh9Bxb7aIieofwU1eB980nSeO55lrEIVXs1',

}
r= sss.post(url, headers = my_headers, data = my_data)
print r.url, r.status_code, r.history
webbrowser.open(r.url, new=0, autoraise=True)

我想问为什么r.url = http://teaching.nkfust.edu.tw/Course/student/today.aspx

webbrowser.open（r.url，new = 0，autoraise = True）这是开放的 http://teaching.nkfust.edu.tw/Course/Login.aspx?ReturnUrl=%2FCourse%2Fstudent%2Ftoday.aspx

如果我的问题得到了正确的解答，您的网址就会被更改为＆＃34;使用request.get（）时。这是一种常见的重定向。所以你必须不允许它。

r=sss.get(url,headers=my_headers, allow_redirects=False)
