带有网络存档的 Python 报纸(回归机器)

Question

我正在尝试使用 Python 库 newspaper来自 Wayback Machine 的文件，存储已存档的旧版本网站。理论上，可以从这些文件中查询和下载旧的新闻文章。
例如，下面的代码查询文件 CNBC 对于特定的存档日期。

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

尽管存档的网站本身包含指向 2016 年 12 月 1 日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，您会获得如下网址:

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

这些不是来自这个 CNBC 存档版本的实际文章。然而，报纸与今天的 CNBC 版本配合得很好。 .
我想它会因为 url 的格式(包含两个 http s)而感到困惑。有人对如何从 Wayback Machine 中提取文章有任何建议吗？文件？

Answer 1

这是一个有趣的问题，我将把它添加到我的 Newspaper Usage Overview 中。 GitHub 上提供的文档。
我尝试使用 news.build，但我无法让它正常工作，所以我使用了报纸 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))

上面的例子输出这个:
