java web 页面url传值中文编码&解码问题

1、创建web项目：

2、2：在js中添加js:

function sssss(){

var act_id = ${gift.gid} ;

var user_id= ${sessionScope.user.id};

var title = "${gift.gname }";

//var cont = ${url };

var itype = "3";

var tiltes = encodeURI(encodeURI(title));

var url = "<%=path %>/share/tosharegift.action?act_id=" +act_id +"&user_id=" + user_id +"&title=" + tiltes +"&itype=" + itype ;

//+"&cont="+cont;

$.ajax({

url:url,

type:"post",

       dataType:'json',

       success:function(data){

        if(data.success){

        alert("分享成功！");

        }else{

            alert(data.errorMsg);

           }

       },

    error:function(response){

alert("分享 失败！");

       }

});

3、在action中进行解码：、

String title = getWebParams().getString("title");

String cont = getWebParams().getString("cont");

if(title != null){

//编码

try {

title = new String(title.getBytes("iso-8859-1"),"utf-8");

title = URLDecoder.decode(title, "utf-8");

} catch (UnsupportedEncodingException e) {

e.printStackTrace();

}

}
