$.ajax提交,后台接受到的值总是乱码？明天再总结

//首先说明，我的服务器和页面编码都是GBK，所以尝试了很多种GBK的方式前台：function printFunction(){window.print();$.ajax({url  : '/tpzssearch/handleRecordLog.action',type : 'post',                     //各种尝试//processData : true,//scriptCharset:'GBK',// contentType: 'application/x-www-form-urlencoded; charset=gbk', //  contentType: "application/x-www-form-urlencoded;charset=gbk",data : {tablename:'<%=java.net.URLEncoder.encode(tablename,"UTF-8")%>',search:'<%= java.net.URLEncoder.encode(session.getAttribute("oradetailQueryString").toString(),"UTF-8")%>',info:'<%=java.net.URLEncoder.encode(rs,"UTF-8")%>'}});}

后台：//gbk互转UTF-8试过、ISO-8859-1互转gbk试过、ISO-8859-1互转UTF-8试过public static String toUTF(String arg) {        if (arg != null && arg.trim().length() > 0) {            try {                arg = new String(arg.getBytes("GBK"), "UTF-8");            } catch (Exception e) {            }        } else {            arg = "";        }        return arg;    }logModel.setTableName(URLDecoder.decode(request.getParameter("tablename"),"UTF-8"))最后：就是传参数时java.net.URLEncoder.encode(tablename,"UTF-8")，接收参数时URLDecoder.decode(request.getParameter("tablename"),"UTF-8")，解决了

解决乱码的4个方向：

方法一：
在后台中使用request.setCharacterEncoding("UTF-8");

方法二：
$.ajax({
type:'post',
contentType:'application/x-www-form-urlencoded; charset=UTF-8'
});

方法三：

public static String toUTF(String arg) {
        if (arg != null && arg.trim().length() > 0) {
            try {
                arg = new String(arg.getBytes("GBK"), "UTF-8");
            } catch (Exception e) {
            }
        } else {
            arg = "";
        }
        return arg;
    }

方法四：

URLDecoder
