python采集微信公众号文章
本文实例为大家分享了python采集微信公众号文章的具体代码，供大家参考，具体内容如下
在python一个子目录里存2个文件，分别是：采集公众号文章.py和config.py。 代码如下：
1.采集公众号文章.py

if __name__ == '__main__':

2.config.py代码：
#爬取公众号文章 PROXY_POOL_URL = 'http://127.0.0.1:5000/get' KEYWORD ='计算机等级二级' # 输入关键词 MONGO_URI = 'localhost' MONGO_DB = 'data' MAX_COUNT = 5
其中，config.py中KEYWORD为查找关键词，可以根据需要更改。经实测，运行"采集公众号文章.py"成功！若因受限不成功，可多运行几次。
