要提取微信群的关键信息,我们可以使用Python编写一个微信聊天记录爬虫,然后分析聊天记录提取关键信息。
以下是一个简单的示例:
1. 安装所需库:
```bash pip install wxpy pip install beautifulsoup4 pip install requests ```
2. 编写微信聊天记录爬虫:
```python import wxpy import requests from bs4 import BeautifulSoup
def get_chat_history(user_id, chat_history_url): headers = { 'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/58.0.3029.110 Safari/537.3'} response = requests.get(chat_history_url, headers=headers) response.encoding = 'utf-8' soup = BeautifulSoup(response.text, 'html.parser')
chat_history = [] for item in soup.find_all('li', class_='msg'): msg = {} msg['user_id'] = item.find('img', class_='avatar').attrs['data-userid'] msg['content'] = item.find('span', class_='txt').text.strip() chat_history.append(msg) return chat_history
def extract_key_info(chat_history): key_info = [] for msg in chat_history: if 'key_word' in msg: key_info.append(msg['content']) return key_info def main():
# 登录微信 bot = wxpy(cache_path='./cache', login_wait=60) # 获取与指定用户聊天的记录 chat_history_url = 'https://chat.weixin.qq.com/history/rev/page/{}'.format(bot.login_status['base_req_url']) user_id = 'friend_id'
# 替换为你要提取关键信息的用户ID chat_history = get_chat_history(user_id, chat_history_url) # 提取关键信息 key_info = extract_key_info(chat_history)
# 输出关键信息 for info in key_info: print(info) if __name__ == '__main__': main() ```
以上代码示例中,我们首先登录微信,然后获取与指定用户的聊天记录,并提取关键信息。这里的关键词提取只是一个简单的示例,你可以根据实际需求修改或优化提取规则。 请注意,这个示例仅适用于微信网页版聊天记录。如果是手机端的聊天记录,需要进一步研究微信API和移动端网页的解析方法。此外,提取关键信息的部分只是一个简单的示例,你可以根据实际需求修改或优化提取规则。
