使用python来登录asp网站和登录其他网站差不多,只是因为asp页面在每次请求的时候都要带上viewstate,因此使用python来登录的话就多了一个步骤,获得这个页面的viewstate之后带上这个和你要post或get到该页面的请求数据就好了,下面这段程序是登录一个asp系统,然后搜索某些数据并将这些数据保存下来.

import urllib2 from bs4 import BeautifulSoup import urllib import cookielib import re import httplib import time 
loginUrl="登录地址"
headers={"User-Agent":"Mozilla/5.0 (Windows NT 6.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/37.0.2062.120 Safari/537.36"}

pageOpener = urllib2.build_opener(urllib2.HTTPCookieProcessor(studentCookie)) 
loginPageRequest = urllib2.Request(loginUrl)  
loginPageHTML = pageOpener.open(loginPageRequest).read() """ 
s=requests.Session() 
s.headers.update(headers) 
r=s.get(loginUrl) 
""" print loginPageHTML 
soup=BeautifulSoup(loginPageHTML) 
__VIEWSTATE=soup.find(id="__VIEWSTATE")['value'] 
__EVENTVALIDATION=soup.find(id="__EVENTVALIDATION")['value'] 
 print __VIEWSTATE print __EVENTVALIDATION
