我怎么可以登录到使用python一个网站吗？ [英] How can I log into a website using python?

问题描述

我已经看到了这个其他问题：<一href=\"http://stackoverflow.com/questions/189555/how-to-use-python-to-login-to-a-webpage-and-retrieve-cookies-for-later-usage\">How使用Python登录到一个网页，检索饼干供以后使用？

I've seen this other question: How to use Python to login to a webpage and retrieve cookies for later usage?

然而，答案的一个简单的修改并没有为我工作，所以我不知道我怎么能实现我的目标。

However, a straightforward modification of that answer did not work for me, so I'm wondering how I can achieve my goal.

要放弃背景下，我试图登录到 https://mog.com/hp/sign_in ，然后从以下页面提取我的播放列表的名称： http://mog.com/my_mog/playlists

To give context, I'm trying to log into https://mog.com/hp/sign_in and then extract the names of my playlists from the following page: http://mog.com/my_mog/playlists

我想这应该是pretty简单的人谁知道他们在做什么。一些基本的code登录到该网站，访问受密码保护的网页将是巨大的，它甚至会更好，如果你能在一两句话解释了code每一行是干什么的，所以我能更好地理解什么样的code在做什么。

I think this should be pretty straightforward for someone who knows what they are doing. Some basic code to log into the site and access a password-protected page would be great, and it would be even better if you could explain in a sentence or two what each line in the code is doing, so I can get a better understanding of what the code is doing.

推荐答案

试着用机械化：

import mechanize
br=mechanize.Browser()
br.open('https://mog.com/hp/sign_in')
br.select_form(nr=0) 
br['user[login]']= your_login
br['user[password]']= your_password
br.submit()
br.retrieve('http://mog.com/my_mog/playlists','playlist.html')

编辑：结果
让你的链接，你可以补充一点：

to get your links you can add this:

for link in br.links():
    print link.url, link.text

或从 playlist.html 开始，你可以使用的 Beautifulsoup 和正则表达式：

or, starting from playlist.html, you could use Beautifulsoup and regex:

from BeautifulSoup import BeautifulSoup
import re
soup = BeautifulSoup(file('playlist.html').read())
for link in soup.findAll('a', attrs={'href': re.compile("your matching re")}):
    print link.get('href')
