Question

这是我的代码：

from requests import session

payload = {
    'action': 'login',
    'TB1$TabPanel1$txt_user_name': '2016XXXXXXXXX',
    'TB1$TabPanel1$txt_password': '6XXXXXXXX'
}

with session() as c:
    c.post('http://erp.sangamuniversity.ac.in/Default.aspx', data=payload)
    response = c.get('http://erp.sangamuniversity.ac.in/Student/Student_Home.aspx')
    print response.text

print语句在登录后（http://erp.sangamuniversity.ac.in/Default.aspx＆＃39;）打印登录页面的html源代码（http://erp.sangamuniversity.ac.in/Student/Student_Home.aspx）而不是主页。为什么？（提供实际的用户名和密码用于测试脚本）。

Answer 1

看起来Default.aspx页面实际上是发布到default1.aspx。

<form id="Form1" method="post" action="default1.aspx" onsubmit="javascript:return WebForm_OnSubmit();">

您应该更新脚本以发布到default1.aspx而不是Default.aspx。

Answer 2

它发送给default1.aspx的数据似乎并不那么简单。以下是我尝试登录网站时发现的Form Data（当然使用假用户名和密码）。

以下代码已经过测试。

from requests import session

payload = {
    'TB1_ClientState':'{"ActiveTabIndex":0,"TabEnabledState":[true,true,true],"TabWasLoadedOnceState":[true,false,false]}',
    '__EVENTTARGET':'',
    '__EVENTARGUMENT':'',
    '__VIEWSTATE':[enter your own viewstate on the page],
    '__EVENTVALIDATION':[enter your own eventvalidation on the page],
    'TB1$TabPanel1$txt_user_name': [enter your own username],
    'TB1$TabPanel1$txt_password': [enter your own password],
    'TB1$TabPanel1$btn_log':'Login',
    'TB1$tbpanel2$F_drp_college':1,
    'TB1$tbpanel2$tb_emp_id':'',
    'TB1$tbpanel2$tb_emp_password':'',
    'TB1$TabPanel2$txtusernameparent':'',
    'TB1$TabPanel2$txtPasswordParent':''
}

with session() as c:
    c.post('http://erp.sangamuniversity.ac.in/Default1.aspx', data=payload)
    response = c.get('http://erp.sangamuniversity.ac.in/Student/Student_Home.aspx')
    print response.text

您可以查找aspNetHidden课程以获取viewstate和eventvalidation。希望这将有助于您的情况：）
