如何“登录"；使用Python的“请求"模块访问网站? [英] How to "log in" to a website using Python's Requests module?

问题描述

我正在尝试使用Python中的请求"模块发布一个登录网站的请求，但它实际上无法正常工作.我是新来的...所以我不知道是否应该制作我的用户名和密码cookie或我发现的某种类型的HTTP授权内容(??).

I am trying to post a request to log in to a website using the Requests module in Python but its not really working. I'm new to this...so I can't figure out if I should make my Username and Password cookies or some type of HTTP authorization thing I found (??).

from pyquery import PyQuery
import requests

url = 'http://www.locationary.com/home/index2.jsp'

所以现在，我认为我应该使用发布"和cookie....

So now, I think I'm supposed to use "post" and cookies....

ck = {'inUserName': 'USERNAME/EMAIL', 'inUserPass': 'PASSWORD'}

r = requests.post(url, cookies=ck)

content = r.text

q = PyQuery(content)

title = q("title").text()

print title

我有种感觉，我在做饼干的事情做错了...我不知道.

I have a feeling that I'm doing the cookies thing wrong...I don't know.

如果未正确登录，则首页标题应显示在"Locationary.com"上；如果登录，则应为首页".

If it doesn't log in correctly, the title of the home page should come out to "Locationary.com" and if it does, it should be "Home Page."

如果您可以向我解释一些有关请求和cookie的事情，并帮助我解决这个问题，我将不胜感激. :D

If you could maybe explain a few things about requests and cookies to me and help me out with this, I would greatly appreciate it. :D

谢谢.

...它仍然还没有真正起作用.好的...所以这就是登录前主页HTML的内容:

...It still didn't really work yet. Okay...so this is what the home page HTML says before you log in:

</td><td><img src="http://www.locationary.com/img/LocationaryImgs/icons/txt_email.gif">    </td>
<td><input class="Data_Entry_Field_Login" type="text" name="inUserName" id="inUserName"  size="25"></td>
<td><img src="http://www.locationary.com/img/LocationaryImgs/icons/txt_password.gif"> </td>
<td><input  class="Data_Entry_Field_Login"  type="password" name="inUserPass"     id="inUserPass"></td>

所以我认为我做对了，但是输出仍然是"Locationary.com"

So I think I'm doing it right, but the output is still "Locationary.com"

第二次

我希望能够长时间保持登录状态，并且每当我请求该域下的页面时，我都希望内容显示出来就像登录一样.

I want to be able to stay logged in for a long time and whenever I request a page under that domain, I want the content to show up as if I were logged in.

推荐答案

如果您想要的信息在页面上，则在登录后立即被定向到...

让我们改为调用ck变量payload，就像在 Python请求文档:

If the information you want is on the page you are directed to immediately after login...

Lets call your ck variable payload instead, like in the python-requests docs:

payload = {'inUserName': 'USERNAME/EMAIL', 'inUserPass': 'PASSWORD'}
url = 'http://www.locationary.com/home/index2.jsp'
requests.post(url, data=payload)

否则...
