解决jsp 的URI 中的中文传参问题

<%! public String GBToISO(String str)
{try{byte temp[]=str.getBytes("GB2312");
str=new String(temp,"ISO-8859-1");
return str;
}catch(Exception e){return str;}}

response.sendRedirect(GBToISO("errmsg.<SPAN class=hilite1>jsp</SPAN>?errmsg=添加客户信息成功"));%>

<%! public String GBToISO(String str)   
{try{byte temp[]=str.getBytes("GB2312");   
str=new String(temp,"ISO-8859-1");   
return str;   
}catch(Exception e){return str;}}   
  
response.sendRedirect(GBToISO("errmsg.jsp?errmsg=添加客户信息成功"));%>  

超连接中profession为中文

<a href="cust_totallist.<SPAN class=hilite1>jsp</SPAN>?action=delete&page=<%=intCurrentPage%>&cust_id=<%=rs.getInt("id")%>&profession=<%=java.net.<SPAN class=hilite2>URL</SPAN>Encoder.encode(profession,"ISO-8859-1")%>">删除</a>
////////////cust_totallist.<SPAN class=hilite1>jsp</SPAN>中取profession值
String profession=java.net.<SPAN class=hilite2>URL</SPAN>Decoder.decode(request.getParameter("profession").trim(),"ISO-8859-1");

<a href="cust_totallist.jsp?action=delete&page=<%=intCurrentPage%>&cust_id=<%=rs.getInt("id")%>&profession=<%=java.net.URLEncoder.encode(profession,"ISO-8859-1")%>">删除</a>   
////////////cust_totallist.jsp中取profession值   
String profession=java.net.URLDecoder.decode(request.getParameter("profession").trim(),"ISO-8859-1");  

可见,URL中编码格式为ISO-8859-1,处理中文只需将编码格式转换ISO-8859-1
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");

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.<SPAN class=hilite1>jsp</SPAN>?<SPAN class=hilite2>url</SPAN>=<%=java.net.<SPAN class=hilite2>URL</SPAN>Encoder.encode("编码的是这里","GB2312")%>">点击这里</a>
<%
//request.setCharacterEncoding("GBK");
if(request.getParameter("<SPAN class=hilite2>url</SPAN>")!=null)
{
str=request.getParameter("<SPAN class=hilite2>url</SPAN>");
str=java.net.<SPAN class=hilite2>URL</SPAN>Decoder.decode(str,"GB2312");
str=new String(str.getBytes("ISO-8859-1"));
out.print(str);
}
%>

<%@ 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;
}
}

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 <SPAN class=hilite2>URL</SPAN>encode(sStr)
{
return escape(sStr).
replace(/\+/g, '%2B').
replace(/\"/g,'%22').
replace(/\'/g, '%27').
replace(/\//g,'%2F');
}

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>

<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");
