带web存档的Python报纸（回送机）

我正在尝试将Python库与来自的存档一起使用，它存储存档的网站的旧版本。理论上，旧的新闻文章可以从这些档案中查询和下载

例如，下面的代码查询存档中的CNBC，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 )

虽然存档的网站本身包含2016-12-01年的实际新闻文章链接，但报纸模块似乎没有收到这些链接。相反，您会得到如下URL：

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

这些不是CNBC存档版本中的实际文章。然而，报纸在今天的版本中效果很好

我认为它会因为url的格式（包含两个

http

s）而变得混乱。有人对如何从档案中提取文章有什么建议吗？

这是一个有趣的问题，我将把它添加到GitHub上的文档中

我尝试使用paper.build，但无法使其正常工作，所以我使用了paper 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))

上面的示例输出了以下内容：
