标题: getJson传给后台的参数乱码 [打印本页]

作者: look_w 时间: 2019-4-20 13:58 标题: getJson传给后台的参数乱码

项目中使用spring sturts action 传值出现乱码而且google浏览器中没乱码  ie下传值乱码

在jsp中使用getJson传值

$.getJSON("<%=basePath%>/query/searchCompareTable?geneName="+geneName+"&fieldName="+fieldName+"&minValue="+minValue+"&maxValue="+maxValue, function(datatable) {

其中geneName 和 fieldName是中文或者英文名

java中 action接收为set接收

   private String geneName;
      private String fieldName;
      private double minValue;
      private double maxValue;
      public void setGeneName(String geneName) {
         this.geneName = geneName;
      }
      public void setFieldName(String fieldName) {
         this.fieldName = fieldName;
      }
public void setMinValue(double minValue) {
         this.minValue = minValue;
      }
public void setMaxValue(double maxValue) {
         this.maxValue = maxValue;
      }

这个时候服务器的tomcat的server.xml配置已经设置成 utf-8

jsp页面头部为

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
      String path = request.getContextPath();
      String basePath = request.getScheme() + "://"
            + request.getServerName() + ":" + request.getServerPort()
            + path + "/";
%>
<%@taglib prefix="s" uri="/struts-tags"%>

<!DOCTYPE html>
<html>
<head>
<base href="<%=basePath%>">
<meta charset="UTF-8">
<title>gseInfo</title>
<link type="text/css" rel="stylesheet" href="css/skin.css" />
<link type="text/css" rel="stylesheet" href="css/genesboxUI.css" />
<script type="text/javascript" src="js/jquery-1.10.2.min.js"></script>
<script src="js/controls.js"></script>
<script>
      document.createElement('header');
      document.createElement('nav');
      document.createElement('aside');
      document.createElement('section');
</script>

这个时候发现中文参数乱码

解法一

解决办法

jsp中 getJson 中英文参数加上一次转码

encodeURI(geneName)

$.getJSON("<%=basePath%>/query/searchCompareTable?geneName="+encodeURI(geneName)+"&fieldName="+encodeURI(fieldName)+"&minValue="+minValue+"&maxValue="+maxValue, function(datatable) {

action中不解码

解法二

解决办法

jsp中 getJson 中英文参数加上两次转码

encodeURI(encodeURI(geneName))

encodeURI(encodeURI(fieldName))

如下:

$.getJSON("<%=basePath%>/query/searchCompareTable?geneName="+encodeURI(encodeURI(geneName))+"&fieldName="+encodeURI(encodeURI(fieldName))+"&minValue="+minValue+"&maxValue="+maxValue, function(datatable) {

action中解码

      compareResultHtml="";
         try {
            geneName=URLDecoder.decode(geneName,"utf-8");
            fieldName=URLDecoder.decode(fieldName,"utf-8");
         } catch (UnsupportedEncodingException e1) {
            e1.printStackTrace();
         }
