问题描述

我正在制作包含作者出版日期和新闻文章正文的文本文件。我有代码可以做到这一点,但我需要Newspaper3k首先从这些文章中识别相关信息。由于用户代理规范之前一直是个问题,所以我还指定了用户代理。这是我的代码,因此您可以跟随。这是Python 的。version 3.9.0

import time, os, random, nltk, newspaper 

from newspaper import Article, Config

user_agent = 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_6) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124  Safari/537.36'

config = Config()
config.browser_user_agent = user_agent

url = 'https://www.eluniversal.com.mx/estados/matan-3-policias-durante-ataque-en-nochistlan-zacatecas'
article = Article(url, config=config)
article.download()
#article.html #
article.parse()
article.nlp()

article.authors
article.publish_date
article.text 

为了更好地理解为什么这个案例特别令人费解,请将我上面提供的链接替换为这个链接,然后重新运行代码。使用此链接,代码现在可以正确运行,并返回作者、日期和文本。使用上面代码中的链接,它没有。我在这里俯瞰什么?

解决方案


显然,Newspaper 要求我们指定我们感兴趣的语言。这里的代码由于某种奇怪的原因仍然没有提取作者,但这对我来说已经足够了。这是代码,如果其他人会从中受益。


#
# Imports our modules
#

import time, os, random, nltk, newspaper
from newspaper import Article
from googletrans import Translator
translator = Translator()

# The link we're interested in

url = 'https://www.eluniversal.com.mx/estados/matan-3-policias-durante-ataque-en-nochistlan-zacatecas'


#
# Extracts the meta-data
#

article = Article(url, language='es')
article.download()
article.parse()
article.nlp()

#
# Makes these into strings so they'll get into the list
#

authors = str(article.authors)
date = str(article.publish_date)
maintext = translator.translate(article.summary).text


# Makes the list we'll append

elements = [authors+ "\n", date+ "\n", maintext+ "\n", url]

for x in elements:
    print(x)
