javascript通过url向jsp页面传递中文参数乱码解决方法
解决方法:在传递参数前将中文参数进行两次编码,jsp页面获取参数后对中文参数进行一次解码,中文参数就不会变为乱码了!
参考例子:
<%@ page language="java" contentType="text/html; charset=UTF-8"
pageEncoding="UTF-8"%>
<%@ page import="java.net.*" %>
<%
String str0="";
String str1="";
if(request.getParameter("param0")!=null){
str0=request.getParameter("param0");//直接获取中文参数
}
try{
if(request.getParameter("param1")!=null){
str1=URLDecoder.decode(request.getParameter("param1"),"utf-8");//对中文参数进行解码
}
}catch(Exception e){
e.printStackTrace();
}
%>
