关于python对于aspx网页的post提交

这二天看了一下python，比较这种编程思想和开源。试了一下自己的ASPX想实现一个自动登录！

结果查询了许久没有结果，老是返回到登录页面，后请教单位的大牛讲了一下，原来还是有很多数据要提交。

晚上继续G，终于找到了解决方案。特记录下来，以后备后查！

解决方案一、

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,

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

from robobrowser import RoboBrowser

# This retrieves __VIEWSTATE and friends
browser.open(login_url)

signin = browser.get_form(id=aspnetForm)
