仅使用 python 请求打开 URL 然后继续下载文件

Question

我正在尝试使用 Python 的请求模块从网站下载文件。

但是，仅当直接从下载页面单击下载链接时，该站点才允许我下载文件。 因此，使用请求，我尝试首先使用requests.get() 访问下载页面的 URL，然后继续下载文件。但不幸的是，这似乎不起作用。要求我首先打开下载页面的文本被写入 file.torrent"

import requests

def download(username, password):
    with requests.Session() as session:
        session.post('https://website.net/forum/login.php', data={'login_username': username, 'login_password': password})

        # Download page URL
        requests.get('https://website.net/forum/viewtopic.php?t=2508126')

        # The download URL itself
        response = requests.get('https://website.net/forum/dl.php?t=2508126')

        with open('file.torrent', 'wb') as f:
            f.write(response.content)

download(username='XXXXX', password='YYYYY')

直接从下载页面下载时的响应（有效）：

Answer 1

这对我有用：

data={'login_username': username, 'login_password': password, 'login': ''}

并使用session.get() 而不是requests.get()
