无法使用Python的请求模块登录到ASP.NET网站

我正在尝试使用Python中的requests模块登录到ASP.NET网站。无法使用Python的请求模块登录到ASP.NET网站

在网站中手动登录时，我可以看到以下标题以及Cookie。

以下是我用来登录到使用Python/Django网站的脚本。

import requests 
with requests.Session() as c: 
    url = 'http://www.noobmovies.com/accounts/login/?next=/' 
    USERNAME = 'user name' 
    PASSWORD = 'password' 
    c.get(url) 
    csrftoken = c.cookies['csrftoken'] 
    login_data = dict(csrfmiddlewaretoken=csrftoken, username=USERNAME, password=PASSWORD, next='/') 
    c.post(url, data=login_data, headers={"Referer":"http://www.noobmoviews.com/"}) 
    page = c.get('http://www.noobmovies.com/user/profile/0/') 

    print page.status_code

但我不知道如何登录到ASP.NET网站。如何在ASP.NET网站上发布数据？

我最初使用了请求+ bs4，但是我遇到了类似的问题，我正在使用ASPX网站报废。我发现了另一个名为robobrowser的库，它包装请求+ bs4。借助此功能，您无需在与ASPX站点进行交互时手动设置项目，如“__VIEWSTATE”和朋友。

from robobrowser import RoboBrowser 

url = ' http://www11.davidsonsinc.com' 
login_url = url + '/Login/Login.aspx' 

username = "username" 
password = "password" 

browser = RoboBrowser(history=True) 
# This retrieves __VIEWSTATE and friends 
browser.open(login_url) 

signin = browser.get_form(id='aspnetForm') 
signin["ctl00$ContentPlaceHolderNavPane$LeftSection$UserLogin$UserName"].value = username 
signin["ctl00$ContentPlaceHolderNavPane$LeftSection$UserLogin$Password"].value = password 
signin["ctl00$ContentPlaceHolderNavPane$LeftSection$UserLogin$LoginButton"].value = "Log In" 
browser.submit_form(signin) 
print browser.url
