UserAgent流量标识解析

ua流量标识信息依赖

1、爬虫维护ua流量标识

需要维护流量标识对应的中文池子，便于功能化、技术产品化，如：micromessenger-微信；meituan-美团app

2、爬虫维护内置浏览器

通过特殊内置浏览器识别流量来源，如下ua：

Mozilla/5.0 (Linux; U; Android 9; zh-CN; V1824A Build/PKQ1.181216.001) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/57.0.2987.108 UCBrowser/12.8.2.1062 Mobile Safari/537.36

解析结果如下列表示例：
