"所谓 UA（User Agent / 用户代理），最初是指浏览器告知网站管理员，本浏览器支持的类型和框架，让网站管理员以支持的模式结构向浏览器发送页面，呈现给用户浏览。演变到今天，网站管理员为了给用户带呈现最佳的页面效果，为了使不同浏览器展现同样的网站页面，通过浏览器获取用户的系统信息，包括硬件平台、系统软件、应用软件和用户个人偏好，然后通过服务器解析后以适合用户的页面类型发送到浏览器。

# 安装 pip install fake-useragent# 使用 from fake_useragent import UserAgent ua = UserAgent() # 随机谷歌UA chrome = ua.Chrome # 随机IE的UA ie = ua.ie # 随机火狐UA firefox = ua.Firefox # 随机浏览器的UA firefox = ua.random # 忽略大小写的，比如：ua.ie可写成ua.IE # 如果实例化时出现报错，可尝试以几种方式实例化： # ua = UserAgent(use_cache_server=False) # ua = UserAgent(cache=False) # ua = UserAgent(verify_ssl=False)
