Java通过浏览器请求头（User-Agent）获取 浏览器类型，操作系统类型，手机机型
来源：程序员人生 发布时间：2014-11-22 09:13:17 阅读次数：3939次
User Agent中文名为用户代理，简称 UA，它是1个特殊字符串头，使得http://www.wfuyu.com/server/能够辨认客户使用的操作系统及版本、CPU 类型、阅读器及版本、阅读器渲染引擎、阅读器语言、阅读器插件等。
1些网站常常通过判断 UA 来给不同的操作系统、不同的阅读器发送不同的页面，因此可能造成某些页面没法在某个阅读器中正常显示，但通过假装 UA 可以绕过检测。
1：取得阅读器要求头中的User-Agent
String ua = request.getHeader("User-Agent")
2：取得阅读器类型，操作系统类型：(注意，UserAgent类在UserAgentUtils.jar中，自行下载)
UserAgent userAgent = UserAgent.parseUserAgentString(request.getHeader("User-Agent"));
Browser browser = userAgent.getBrowser();
OperatingSystem os = userAgent.getOperatingSystem();
3：取得手机类型：
方案1：http://www.wfuyu.com/help/zz/表达式
通过视察规律，得出以下表达式：
;s?([^;]+?)s?(Build)?/
Java代码：
Pattern pattern = Pattern.compile(";s?(S*?s?S*?)s?(Build)?/");
Matcher matcher = pattern.matcher(userAgent);
String model = null;
if (matcher.find()) {
model = matcher.group(1).trim();
log.debug("通过userAgent解析出机型：" + model);
}
以下为部份UserAgent，供测试，可以直接在EditPlus里验证。
