文章摘要

该文章介绍了一段使用Python编写的代码，用于批量下载微信公众号的文章、音频和视频。代码的核心功能包括： 1. **批量下载功能**：通过正则表达式提取文章链接并下载对应的音频、视频和文章内容。2. **处理流程**：首先获取文章链接，然后提取文章标题、日期，再分别下载音频和视频。文章内容可进一步转换为PDF。3. **关键词处理**：代码使用正则表达式提取关键信息，如标题和日期，并处理异常情况（如错误下载）时生成随机文件名。该代码适用于需要快速获取微信公众号多篇文章资源的场景，同时支持将文章内容转换为PDF格式。

之前发过Python批量抓取公众号的教程，这次不抓取公众号阅读数数据，批量下载公众号文章，音频和视频，直接上代码：

def video(res, headers,date):
vid = re.search(r’wxv_.{19}’,res.text)
# time.sleep(2)
if vid:
vid = vid.group(0)
print(‘视频id’,vid)
url = f’https://mp.weixin.qq.com/mp/videoplayer?action=get_mp_video_play_url&preview=0&vid={vid}’
data = requests.get(url,headers=headers,timeout=1).json()
video_url = data[‘url_info’][0][‘url’]
video_data = requests.get(video_url,headers=headers)
print(‘正在下载视频：’+trimName(data[‘title’])+’.mp4′)
with open(date+’___’+trimName(data[‘title’])+’.mp4′,’wb’) as f:
f.write(video_data.content)
def audio(res,headers,date,title):
aids = re.findall(r'”voice_id”:”(.*?)”‘,res.text)
time.sleep(2)
tmp = 0
for id in aids:
tmp +=1
url = f’https://res.wx.qq.com/voice/getvoice?mediaid={id}’
audio_data = requests.get(url,headers=headers)
print(‘正在下载音频：’+title+’.mp3′)
with open(date+’___’+trimName(title)+’___’+str(tmp)+’.mp3′,’wb’) as f5:
f5.write(audio_data.content)
url = input(‘请输入文章链接：’)
response = requests.get(url, headers=headers)
urls = re.findall(‘<a target=”_blank” href=”(https?://mp.weixin.qq.com/s?.*?)”‘,response.text)
urls.append(url)
print(‘文章总数’,len(urls))
for mp_url in urls:
res = requests.get(html.unescape(mp_url),proxies={‘http’: None,’https’: None},verify=False, headers=headers)
content = res.text.replace(‘data-src’, ‘src’).replace(‘//res.wx.qq.com’, ‘https://res.wx.qq.com’)
try:
title = re.search(r’var msg_title = ‘(.*)”, content).group(1)
ct = re.search(r’var ct = “(.*)”;’, content).group(1)
date = time.strftime(‘%Y-%m-%d’, time.localtime(int(ct)))
print(date,title)
audio(res,headers,date,title)
video(res,headers,date)
with open(date+’_’+title+’.html’, ‘w’, encoding=’utf-8′) as f:
f.write(content)
except Exception as err:
with open(str(randint(1,10))+’.html’, ‘w’, encoding=’utf-8′) as f:
f.write(content)
下载的音频，视频在当前目录，文章html可以用python再转pdf。
