本文实例为大家分享了python下载微信公众号相关文章的具体代码，供大家参考，具体内容如下

目的：从零开始学自动化测试公众号中下载“pytest"一系列文档

1、搜索微信号文章关键字搜索

2、对搜索结果前N页进行解析，获取文章标题和对应URL

主要使用的是requests和bs4中的Beautifulsoup

Weixin.py

import requestsfrom urllib.parse import quotefrom bs4 import BeautifulSoupimport refrom WeixinSpider.HTML2doc import MyHTMLParser class WeixinSpider(object):  def __init__(self, gzh_name, pageno,keyword):  self.GZH_Name = gzh_name  self.pageno = pageno  self.keyword = keyword.lower()  self.page_url = []  self.article_list = []  self.headers = {   'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.110 Safari/537.36'}  self.timeout = 5  # [...] 用来表示一组字符,单独列出：[amk] 匹配 'a'，'m'或'k'  # re+ 匹配1个或多个的表达式。  self.pattern = r'[\\/:*?"<>|\r\n]+'  def get_page_url(self):  for i in range(1,self.pageno+1):   # https://weixin.sogou.com/weixin?query=从零开始学自动化测试&_sug_type_=&s_from=input&_sug_=n&type=2&page=2&ie=utf8   url = "https://weixin.sogou.com/weixin?query=%s&_sug_type_=&s_from=input&_sug_=n&type=2&page=%s&ie=utf8" \     % (quote(self.GZH_Name),i)   self.page_url.append(url)  def get_article_url(self):  article = {}  for url in self.page_url:   response = requests.get(url,headers=self.headers,timeout=self.timeout)   result = BeautifulSoup(response.text, 'html.parser')   articles = result.select('ul[class="news-list"] > li > div[class="txt-box"] > h3 > a ')   for a in articles:    # print(a.text)    # print(a["href"])    if self.keyword in a.text.lower():      new_text=re.sub(self.pattern,"",a.text)      article[new_text] = a["href"]      self.article_list.append(article)   headers = {'User-Agent':      'Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/70.0.3538.110 Safari/537.36'}timeout = 5gzh_name = 'pytest文档'My_GZH = WeixinSpider(gzh_name,5,'pytest')My_GZH.get_page_url()# print(My_GZH.page_url)My_GZH.get_article_url()# print(My_GZH.article_list)for article in My_GZH.article_list: for (key,value) in article.items():  url=value  html_response = requests.get(url,headers=headers,timeout=timeout)  myHTMLParser = MyHTMLParser(key)  myHTMLParser.feed(html_response.text)  myHTMLParser.doc.save(myHTMLParser.docfile)

HTML2doc.py

运行结果：

缺少部分文档，如pytest文档4，是因为搜狗微信文章搜索结果中就没有

以上就是本文的全部内容，希望对大家的学习有所帮助，也希望大家多多支持。
