在Python爬虫中,User-Agent字符串用于模拟不同的浏览器环境,以规避某些网站的反爬虫机制。以下是一些常用的User-Agent值示例:
-
Chrome浏览器:
Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/91.0.4472.124 Safari/537.36
Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_7) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/89.0.4389.82 Safari/537.36
-
Firefox浏览器:
Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:89.0) Gecko/20100101 Firefox/89.0

。
使用这些User-Agent值可以帮助您的爬虫更好地模拟真实用户的浏览行为,从而降低被目标网站识别和封锁的风险。
