URL中文编码问题

后台编码发送：

                 中文编码：nickname=java.net.URLEncoder.encode(nickname);

接收解码：

方法一：

            http://xxx.do?ptname='我是中国人'

            String strPtname = request.getParameter("ptname");

            strPtname = new String(strPtname.getBytes("ISO-8859-1"), "UTF-8");  

方法二：

            
<%@ page contentType="text/html;charset=gb2312" %>

            
<a href="ds.jsp?url=<%=java.net.URLEncoder.encode("编码的是这里","GB2312")%>">点击这里</a>

            

            <%

            //request.setCharacterEncoding("GBK");

            if(request.getParameter("url")!=null)

            {

            
str=request.getParameter("url");

            str=java.net.URLDecoder.decode(str,"GB2312");

            str=new String(str.getBytes("ISO-8859-1"));

            out.print(str);

            }

            
%>

            
==================================

            
public String chinatoString(String str)

                  {

                   String s=str;

                   try

                   {

                    byte tempB[]=s.getBytes("ISO-8859-1");

                    s=new String(tempB);

                    return s;

                   }

                   catch(Exception e)

                   {

                    return s;

                   }

                 }

            
====================================================

            
function URLencode(sStr)

                 {

                   return escape(sStr).

                            replace(/"+/g, '%2B').

                               replace(/""/g,'%22').

                                  replace(/"'/g, '%27').

                                    replace(/"//g,'%2F');

                 }

            

            方法三：

            如果用jstl的话，可以自己写一个el的function，调用URLEncoder.encode来编码。

            
IE缺省对URL后面的参数是不编码发送的，但是tomat缺省是按ISO8859-1来进行URL解码，因此才会出现上述错误。好的做法是：

            1、在URL参数中确保用UTF-8编码之，方法可以用js函数encodeURI()，或调用自定义的el function；

            2、设置server.xml中的Connector熟悉URIEncoding="UTF-8"，确保解码格式与编码格式统一；

方法四：

            
<script>

            for(var i=0;i<document.links.length;i++){

            document.links[i].href=encodeURI(document.links[i].href);

            }

            </script>

            在action中，String s=request.getParameter("s");

            s=new String(s.getBytes("iso-8859-1"),"gbk");
