利用报纸从HTML中提取图像

Question

我无法像通常那样下载文章来实例化文章对象，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报纸以从中提取图像吗？（下面是一个尝试，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

Answer 1

Python模块允许使用代理，但该模块的文档中未列出此功能

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)

与代理和报纸的请求

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

Answer 2

首先，确保您使用的是python3，您之前已经运行过pip3 install newspaper3k

然后，如果第一个版本出现SSL错误（如下所示）

/usr/local/lib/python3.8/site-packages/urllib3/connectionpool.py:981: InsecureRequestWarning: Unverified HTTPS request is being made to host 'fox13now.com'. Adding certificate verification is strongly advised. See: https://urllib3.readthedocs.io/en/latest/advanced-usage.html#ssl-warnings warnings.warn(

您可以通过添加

import urllib3
urllib3.disable_warnings()

这应该起作用：

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)

与python3 <yourfile>.py一起运行

在文章中自己设置html对您没有多大好处，因为这样在其他字段中不会得到任何结果。让我知道这是否解决了问题，或者是否出现任何其他错误
