判断是否是手机访问及手机操作系统

我们现在做的项目,移动端和PC端网站访问的是同一套接口,那么如何在接口中区分是手机访问还是PC短访问呢?

核心思想:根据请求头(request header)来判断,如何请求没有header或伪造user agent则无法判断.

先看一些user agent的实例:

Mozilla/5.0 (Windows NT 6.1; WOW64; rv:35.0) Gecko/20100101 Firefox/35.0

Mozilla/5.0 (iPhone; CPU iPhone OS 8_1_2 like Mac OS X) AppleWebKit/600.1.4 (KHTML, like Gecko) (Engine, like URL) Mobile/12B440 MicroMessenger/6.0.1 NetType/3G+

 

Mozilla/5.0 (Linux; U; Android 4.1.1; en-cn; HTC T528d) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30 MicroMessenger/6.0.2.58_r984381.520 NetType/WIFI

以下是我封装的一套方法

ClientOsInfo 是用于保存访问设备信息的,结构如下(省略getter,setter):

public class ClientOsInfo {
	/***
	 * 比如 Android_3.0
	 */
	private String osTypeVersion;
	/***
	 * Pad或Phone
	 */
	private String deviceType;
	/***
	 * os type
	 */
	private String osType;
	/***
	 * 只是版本号,例如"4.1.1"
	 */
	private String version;
	private String userAgent;
/***
	 * 是否是移动设备
	 * @return
	 */
	public boolean isMobile(){
		return (!ValueWidget.isNullOrEmpty(this.deviceType));
	}
}

 核心方法:

	/***
	 * 当移动端(手机或Pad)访问网页时获取移动端操作系统信息
	 * @param request
	 * @return
	 */
	public static ClientOsInfo getMobileOsInfo(HttpServletRequest request){
		String userAgent=request.getHeader("user-agent");
		if(ValueWidget.isNullOrEmpty(userAgent)){
			userAgent=request.getHeader("User-Agent");
		}
		ClientOsInfo info= HeaderUtil.getMobilOS(userAgent);
		info.setUserAgent(userAgent);
		return info;
	}

 

核心工具类:用于解析user agent

应用场景:

 

通过user agent判断是否是手机

	 * @return
	 */
	public static boolean isMobile(String userAgent)
	{
		userAgent=userAgent.toLowerCase();
		String []mobile_agents = {"240x320","acer","acoon","acs-","abacho","ahong","airness","alcatel","amoi","android","anywhereyougo.com","applewebkit/525","applewebkit/532","asus","audio","au-mic","avantogo","becker","benq","bilbo","bird","blackberry","blazer","bleu","cdm-","compal","coolpad","danger","dbtel","dopod","elaine","eric","etouch","fly ","fly_","fly-","go.web","goodaccess","gradiente","grundig","haier","hedy","hitachi","htc","huawei","hutchison","inno","ipad","ipaq","ipod","jbrowser","kddi","kgt","kwc","lenovo","lg ","lg2","lg3","lg4","lg5","lg7","lg8","lg9","lg-","lge-","lge9","longcos","maemo","mercator","meridian","micromax","midp","mini","mitsu","mmm","mmp","mobi","mot-","moto","nec-","netfront","newgen","nexian","nf-browser","nintendo","nitro","nokia","nook","novarra","obigo","palm","panasonic","pantech","philips","phone","pg-","playstation","pocket","pt-","qc-","qtek","rover","sagem","sama","samu","sanyo","samsung","sch-","scooter","sec-","sendo","sgh-","sharp","siemens","sie-","softbank","sony","spice","sprint","spv","symbian","tablet","talkabout","tcl-","teleca","telit","tianyu","tim-","toshiba","tsm","up.browser","utec","utstar","verykool","virgin","vk-","voda","voxtel","vx","wap","wellco","wig browser","wii","windows ce","wireless","xda","xde","zte"};

@Test
	public void test_userAgent()
	{
		String userAgent="Mozilla/5.0 (Linux; U; Android 4.1.1; en-cn; HTC T528d) AppleWebKit/534.30 (KHTML, like Gecko) Version/4.0 Mobile Safari/534.30 MicroMessenger/6.0.2.58_r984381.520 NetType/WIFI";
