jsp文件名为 index.jsp,其实也可以使用过滤器来进行拦截,然后跳转到其他域名去。
完整代码如下:
复制代码 代码如下:
<%@page import="Java.util.regex.Matcher"%>
<%@page import="Java.util.regex.Pattern"%>
<%@ page language="Java" pageEncoding="UTF-8"%>
<%!
// /b 是单词边界(连着的两个(字母字符 与 非字母字符) 之间的逻辑上的间隔),
// 字符串在编译时会被转码一次,所以是 "//b"
// /B 是单词内部逻辑间隔(连着的两个字母字符之间的逻辑上的间隔)
String phoneReg = "//b(ip(hone|od)|Android|opera m(ob|in)i"
+"|windows (phone|ce)|blackberry"
+"|s(ymbian|eries60|amsung)|p(laybook|alm|rofile/midp"
+"|laystation portable)|nokia|fennec|htc[-_]"
+"|mobile|up.browser|[1-4][0-9]{2}x[1-4][0-9]{2})//b";
String tableReg = "//b(ipad|tablet|(Nexus 7)|up.browser"
+"|[1-4][0-9]{2}x[1-4][0-9]{2})//b";
Pattern phonePat = Pattern.compile(phoneReg, Pattern.CASE_INSENSITIVE);
Pattern tablePat = Pattern.compile(tableReg, Pattern.CASE_INSENSITIVE);
public boolean checkMobile(String userAgent){
if(null == userAgent){
userAgent = "";
}
// 匹配
Matcher matcherPhone = phonePat.matcher(userAgent);
Matcher matcherTable = tablePat.matcher(userAgent);
if(matcherPhone.find() || matcherTable.find()){
return true;
} else {
return false;
}
}
%>
<%
String path = request.getContextPath();
String basePath = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+path+"/";
//
String userAgent = request.getHeader( "USER-AGENT" ).toLowerCase();
if(null == userAgent){
userAgent = "";
}
if(checkMobile(userAgent)){
response.sendRedirect(basePath+"download.html");
//request.getRequestDispatcher("/download.html").forward(request,response);
} else {
response.sendRedirect(basePath+"index.html");
//request.getRequestDispatcher("/index.html").forward(request,response);
}
//
