Python 带有网络存档的报纸（回程机）

Question

我正在尝试使用 Python 库 newspaper with the archives from the Wayback Machine，它存储已存档的旧版本网站。理论上，旧新闻文章可以从这些档案中查询和下载。

例如，以下代码查询 CNBC 的档案以获取特定的存档日期。

import newspaper
url = 'http://web.archive.org/web/20161201123529/http://www.cnbc.com/'
paper = newspaper.build(url, memoize_articles = False )

虽然存档网站本身包含指向 2016-12-01 的实际新闻文章的链接，但报纸模块似乎没有提取它们。相反，您会得到 url，例如：

https://blog.archive.org/2016/10/23/defining-web-pages-web-sites-and-web-captures/

这不是来自 CNBC 存档版本的实际文章。然而，报纸与 today 版本的 CNBC.

配合得很好

我想它会因为 url（包含两个 http 的格式）而变得混乱。有人对如何从 Wayback Machine 档案中提取文章有什么建议吗？

Answer 1

这是一个有趣的问题，我会将其添加到 GitHub 上可用的 Newspaper Usage Overview 文档中。

我尝试使用 newspaper.build，但我无法使其正常工作，所以我使用了 newspaper Source。

from time import sleep
from random import randint
from newspaper import Config
from newspaper import Source

USER_AGENT = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10.15; rv:78.0) Gecko/20100101 Firefox/78.0'

config = Config()
config.browser_user_agent = USER_AGENT
config.request_timeout = 10

wayback_cnbc = Source(url='https://web.archive.org/web/20180301012621/https://www.cnbc.com/', config=config,
                  memoize_articles=False, language='en', number_threads=20, thread_timeout_seconds=2)

wayback_cnbc.build()
for article_extract in wayback_cnbc.articles:
   article_extract.download()
   article_extract.parse()

   print(article_extract.publish_date)
   print(article_extract.title)
   print(article_extract.url)
   print('')

   # this sleep timer is helping with some timeout issues
   # that were happening when querying
   sleep(randint(1,3))

上面的示例输出如下：

None
Media
https://web.archive.org/web/20180301012621/https://www.cnbc.com/media/
    
None
CNBC Video
