以下是我使用 Python/Django 登录网站时使用的脚本一>.

导入请求使用 requests.Session() 作为 c:url = 'http://www.noobmovies.com/accounts/login/?next=/'USERNAME = '用户名'密码 = '密码'c.get(url)csrftoken = c.cookies['csrftoken']login_data = dict(csrfmiddlewaretoken=csrftoken，用户名=用户名，密码=密码，next='/')c.post(url, data=login_data, headers={"Referer":"http://www.noobmoviews.com/"})page = c.get('http://www.noobmovies.com/user/profile/0/')打印 page.status_code

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

I am trying to log in to an ASP.NET website using the requests module in Python.

While logging in manually in the website I can see the following headers as well as cookies.

Following is the script I use to log in in to websites using Python/Django.

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

But I don't know how to log in into an ASP.NET website. How do I post the data on the ASP.NET website?

解决方案

import requests
from bs4 import BeautifulSoup

URL="http://www11.davidsonsinc.com/Login/Login.aspx"
headers={"User-Agent":"Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.120 Safari/537.36"}

username="username"
password="password"

s=requests.Session()
s.headers.update(headers)
r=s.get(URL)
soup=BeautifulSoup(r.content)

VIEWSTATE=soup.find(id="__VIEWSTATE")['value']
VIEWSTATEGENERATOR=soup.find(id="__VIEWSTATEGENERATOR")['value']
EVENTVALIDATION=soup.find(id="__EVENTVALIDATION")['value']

login_data={"__VIEWSTATE":VIEWSTATE,
"__VIEWSTATEGENERATOR":VIEWSTATEGENERATOR,
"__EVENTVALIDATION":EVENTVALIDATION,
"ctl00$ContentPlaceHolderNavPane$LeftSection$UserLogin$UserName":username,
"ctl00$ContentPlaceHolderNavPane$LeftSection$UserLogin$Password":password,
"ctl00$ContentPlaceHolderNavPane$LeftSection$UserLogin$LoginButton":"Log In"}

r=s.post(URL, data=login_data)
print r.url
