随着手持互联网设备不断的加入，平板、手机上网占用了网络很大领域，由此在开发时经常遇到一个问题，需要考虑请求者是一个电脑还是平板还是手机呢？？？这里我人可以使用请求头信息user-agent来判断。
首先来看一级数据：
请求访问来源：
1.win7 64bit IE9
user-agent : Mozilla/5.0 ( MSIE 9.0; Windows NT 6.1; Win64; x64; Trident/5.0)
2.Android 2.3.6 uc
user-agent : Mozilla/5.0 (L U; Android 2.3.6; zh-CN; Nexus S Build/GRK39F) AppleWebKit/534.31 (KHTML, like Gecko) UCBrowser/9.0.1.275 U3/0.8.0 Mobile Safari/534.31
上面是电脑与手机的访问获取到的user-agent数据，通过以上数据可以看到，它们之间的user-agent中会列出不同的系统信息与浏览器信息以及操作系统信息等等，这时我们就可以通过这些数据来分辨请求是来自什么客户端发出的了。
附件1：如何获取请求头信息代码
[code=&java&]Enumeration e =& request.getHeaderNames();
while(e.hasMoreElements()){
String key = (String) e.nextElement();
out.println(key);
out.println(& : &);
out.println(request.getHeader(key));
out.println(&&);

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:

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 {
private String osTypeV
private String deviceT
private String osT
private String userA
public boolean isMobile(){
return (!ValueWidget.isNullOrEmpty(this.deviceType));
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);

Loading...下面java代码判断是手机访问还是PC访问什么地方出错了，手机跳转不到制定页面，等待解答 - ITeye问答
最近在做一个项目，要在判断用户是否是通过手机访问网站的，如果是手机访问网站跳到一个登录页面，如果是用户用电脑访问网站跳到另外一个登录页面。我写了以下代码，但是用手机访问网站的时候，跳转不到制定页面，请求回答。
代码如下
servlet代码如下：
package com.lensoon.
import java.io.IOE
import java.io.PrintW
import javax.servlet.ServletE
import javax.servlet.http.HttpS
import javax.servlet.http.HttpServletR
import javax.servlet.http.HttpServletR

public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
doPost(request,response);
public void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
& logger = Logger.getLogger(this.getClass());
String userAgent = "";
String HTTP_USER_AGENT = request.getHeader("HTTP_USER_AGENT");
System.out.println("aa"+HTTP_USER_AGENT);
String agent = request.getHeader("User-Agent") == null ? "": request.getHeader("User-Agent");//取用户操作系统信息&
& //System.out.println(agent);
if(agent != null &&choose_jsp(agent)==true){
logger.error("跳转到手机百度");
("输出浏览器信息：**********************"+userAgent);
response.sendRedirect("");
& logger.error("跳转到电脑");
& request.getRequestDispatcher("Login.faces").forward(request, response);
public static boolean choose_jsp(String userAgent) {&&&&

输入网址时访问网站的时候会调用这个Login类的构造方法跳转到Login.java这个类中然后用JSF.redirect直接跳转到servlet中，代码如下：
public class Login {
public Login()& {
HttpSession session=JSF.getSession();
if(session.getAttribute("success")==null){
session.setAttribute("success", "pc");
JSF.redirect("checkLoginServlet");//直接跳转到servlet中，是可以跳转的
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
代码就是这样，遇到的问题是，用手机访问的时候跳转不到制定页面，等待解答，急用呀！！！！！！！各位大神，来看看把！！！！！！！！！！！

如果你识别了操作系统，或者能够判断的话，那就是你逻辑问题了，debug吧
