我不能像通常那样下载文章来实例化 Article 对象，如下所示：

from newspaper import Article
url = 'http://fox13now.com/2013/12/30/new-year-new-laws-obamacare-pot-guns-and-drones/'
article = Article(url)
article.download()
article.top_image

但是，我可以从请求中获取 HTML。我可以使用这个原始 HTML 并以某种方式将其传递给 Newspaper 以从中提取图像吗？（以下是尝试，但不起作用）。谢谢

from newspaper import Article
import requests
url = 'http://fox13now.com/2013/12/30/new-year-new-laws-obamacare-pot-guns-and-drones/'
raw_html= requests.get(url, verify=False, proxies=proxy)
article = Article('')
article.set_html(raw_html)
article.top_image

Python 模块Newspaper允许使用代理，但该功能未在模块文档中列出。

报纸代理

from newspaper import Article
from newspaper.configuration import Configuration

# add your corporate proxy information and test the connection
PROXIES = {
           'http': "http://ip_address:port_number",
           'https': "https://ip_address:port_number"
          }

config = Configuration()
config.proxies = PROXIES

url = 'http://fox13now.com/2013/12/30/new-year-new-laws-obamacare-pot-guns-and-drones/'
articles = Article(url, config=config)
articles.download()
articles.parse()
print(articles.top_image)

代理和报纸的请求

import requests
from newspaper import Article

url = 'http://fox13now.com/2013/12/30/new-year-new-laws-obamacare-pot-guns-and-drones/'
raw_html = requests.get(url, verify=False, proxies=proxy)
article = Article('')
article.download(raw_html.content)
article.parse()
print(article.top_image) https://ewscripps.brightspotcdn.com/dims4/default/d49dab0/2147483647/strip/true/crop/400x210+0+8/resize/1200x630!/quality/90/?url=http%3A%2F%2Fmediaassets.fox13now.com%2Ftribune-network%2Ftribkstu-files-wordpress%2F2012%2F04%2Fnational-news-e1486938949489.jpg

首先确保你正在使用python3，你之前运行pip3 install newspaper3k过。

然后，如果您在第一个版本中遇到 SSL 错误（如下所示）

/usr/local/lib/python3.8/site-packages/urllib3/connectionpool.py:981：InsecureRequestWarning：正在向主机“fox13now.com”发出未经验证的 HTTPS 请求。强烈建议添加证书验证。请参阅：https ://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings warnings.warn(

您可以通过添加禁用它们

import urllib3
urllib3.disable_warnings()

这应该有效：

from newspaper import Article
import urllib3
urllib3.disable_warnings()


url = "https://www.fox13now.com/2013/12/30/new-year-new-laws-obamacare-pot-guns-and-drones/"
article = Article(url)
article.download()
print(article.html)

运行python3 <yourfile>.py。

自己在文章中设置 html 对你没有多大好处，因为那样你在其他领域不会得到任何东西。让我知道这是否解决了问题，或者是否弹出任何其他错误！
