Python报纸与Web存档（Wayback Machine）

Question

我正在尝试使用Python库newspaper和Wayback Machine的档案，该机器存储了被归档的旧网站版本。理论上，可以从这些存档中查询和下载旧新闻文章。

例如，下面的代码查询特定存档日期的CNBC存档。

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

尽管存档网站本身包含2016年12月1日的实际新闻文章链接，但报纸模块似乎没有将它们捕捉到。相反，您会得到诸如以下的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。但报纸在今天的CNBC版本中非常好用。

我想它会因为url的格式（包含两个http）而混淆。有人有关于如何从 Wayback Machine存档中提取文章的建议吗？

Answer 1

这是一个有趣的问题，我将把它添加到我的GitHub上可用的报纸使用概述文档中。

我尝试使用newspaper.build，但无法正确运行，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：

希望这个答案能够帮助你查询WayBack Machine上的文章。如果有任何问题，请让我知道。
