麻烦的请求/美丽的汤

问题描述

我想学习使用Python的SOM网络的特点，我想我会写一个脚本在我的大学登录到网页练习。起初，我写了使用的urllib2 的code，但用户alecxe好心使用请求给我提供了一个code / BeautifulSoup （请参见：<一href=\"http://stackoverflow.com/questions/35279961/website-form-login-using-python-urllib2/35280124?noredirect=1#comment58303224_35280124\">Website使用Python的urllib2 ）的形式登陆

I'm trying to learn to use som web features of Python, and thought I'd practice by writing a script to login to a webpage at my university. Initially I wrote the code using urllib2, but user alecxe kindly provided me with a code using requests/BeautifulSoup (please see:Website form login using Python urllib2)

我试图登录到网页。这是不正确的。例如，如果您尝试手动输入错误的长度的PNR，即0，您应该被引导到一个页面看起来像这样：

While the code runs, it always returns the source code of the main page http://reg.maths.lth.se/ which is not correct. For example, if you try to manually enter a pnr of the wrong length, i.e. 0, you should be directed to a page which looks like this:

位于网址 http://reg.maths.lth.se/login/student 的源$ C ​​$ c是主网页的obiously不同。

located at the url http://reg.maths.lth.se/login/student whose source code is obiously different from that of the main page.

有什么建议？

推荐答案

您不分配POST结果响应和刚打印出的结果第一个GET请求。

You aren't assigning the POST result to response, and are just printing out the result of the first GET request.

因此​​，

# submit form
session.post(login_url, data={
    "_token": token,
    "pnr": PNR
})

应

response = session.post(login_url, data={
    "_token": token,
    "pnr": PNR
})
