身份验证和 python 请求 [英] Authentication and python Requests

问题描述

我正在尝试使用请求下载一些文档，但该页面将我重定向到用户登录屏幕并因此下载 HTML 页面.

I am trying to download some documents using requests, but the page is redirecting me to a userlog in screen and therefor downloading the HTML page.

我尝试过:

c=requests.get(url,auth=HTTPBasicAuth('user','pass'))

但我没有通过身份验证.

But I'm not getting authenticated.

我也试过 vanilla 和 Digest.

I've also tried vanilla and Digest.

表单本身看起来像这样:

The form itself looks like this:

<input id="username" name="username" class="required" tabindex="1" type="text" value="" size="25" autocomplete="false"/>
<br/>

<label for="password">Password</label>
<input id="password" name="password" class="required" tabindex="2" type="password" value="" size="25" autocomplete="off"/>

我是否需要将用户名和密码作为有效负载的一部分传递?如果是这样，我该怎么做?到目前为止，我已经尝试了几种不同的方法.

Do I need to pass in the username and password as a part of the payload? If so, how do I do that? I've tried a few different ways so far.

推荐答案

基本上，它与从页面中获取身份验证 ID 并传入 cookie 相关.

Basically, it had to do with grabbing the authentication ID off the page and passing in cookies.

这基本上就是我所做的:

This is basically what I did:

from bs4 import BeautifulSoup as bs
import requests
s = requests.session()
url = r'url_i_care_about'

def authenticate(s, url):
    headers = {'username': 'myuser', 'password': 'mypasss', '_Id': 'submit'}
    page=s.get(url)
    soup=bs(page.content)
    value=soup.form.find_all('input')[2]['value']
    headers.update({'value_name':value})
    auth = s.post(url, params=headers, cookies=page.cookies)
