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+

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
package com.common.util;
import java.util.regex.Matcher;
import java.util.regex.Pattern;
import com.common.bean.ClientOsInfo;
import com.string.widget.util.ValueWidget;

@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";

System.out.println(HeaderUtil.isMobile(userAgent));
}

public static boolean isMicromessengerBrowser(HttpServletRequest request) {
String userAgent = request.getHeader("user-agent").toLowerCase();
