汉语言等特殊字符参数传递乱码 _Web前端

中文等特殊字符参数传递乱码

一、JSP TO JSP

<form method="get" id="editform" action="ss.jsp">
     <input type="text" name="a" id="a" value="aaaa风格化"/>
     <input type="text" name="b" id="b" value="b&*的风格"/>
     <input type="text" name="c" id="c" value="ccc风格化"/>
     <input type="text" name="d" id="d" value="ddd风格化"/>
     <input type="submit" value="sbumit" />
 </form>

<body>
   <%String a=new String(request.getParameter("a").getBytes("ISO8859-1"),"GBK");
        String b=new String(request.getParameter("b").getBytes("ISO8859-1"),"GBK");
        String c=request.getParameter("a");
        String d=request.getParameter("b");  %>
    a:<%=a %>//结果显示乱码
    b:<%=b %>//结果显示乱码
    c:<%=c %>//正常
    d:<%=d %>//正常
  </body>

?如果改用get则刚好相反

二、JSP TO JAVA

1、使用post通过struts传递参数到action

<form method="post" action="<%=path %>/go.do"  >
    <input type="text" name="a" id="a" value="12a*(的风格" /><br>
    <input type="text" name="b" id="b" value="12a*(的风格" />
    <br><input type="text" name="c" id="c" value="12a*(的风格" /><br>
    <input type="text" name="d" id="d" value="12a*(的风格" /><br>
    <input type="submit" vluae="submit"/>
  </form>
action
String a=new String(request.getParameter("a").getBytes("ISO8859-1"),"GBK");//正常
String b=new String(request.getParameter("b").getBytes("ISO8859-1"),"GBK");//正常
String c=request.getParameter("c");//乱码
String d=request.getParameter("d");//乱码

?如果改用get则刚好相反

2、使用编码函数

<script type="text/javascript">
  function show(){
       var f="#wer中文测试";
       f = encodeURIComponent(encodeURIComponent(f));
       test.value = f;
        var url = "servlet/Test?f="+f;
        var rtv = showModalDialog(url,"","dialogWidth:820px; dialogHeight:620px; status:0;help:0;scrolling:auto");
    }
  </script>
  <body><input id="test" value="">   <input type="button" value="TEST" onclick="show()" /> 
  </body>

package com.yourcompany.struts.action;

import java.io.UnsupportedEncodingException;
import java.net.URLDecoder;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;
import com.yourcompany.struts.form.TestForm;

public class TestAction extends Action {
	public ActionForward execute(ActionMapping mapping, ActionForm form,
			HttpServletRequest request, HttpServletResponse response) throws UnsupportedEncodingException {
		TestForm testForm = (TestForm) form;
		
		response.setCharacterEncoding("UTF-8");

		String name=testForm.getName();
		String pwd=testForm.getPwd();
		
		response.setCharacterEncoding("UTF-8");
		String myname=request.getParameter("myname");
		myname=URLDecoder.decode(myname, "UTF-8");
		String mypwd=request.getParameter("mypwd");
		mypwd=URLDecoder.decode(mypwd, "UTF-8");
		
		System.out.println(name);
		System.out.println(pwd);
		System.out.println(myname);
		System.out.println(mypwd);
		
		request.setAttribute("name", name);
		request.setAttribute("pwd", pwd);
		request.setAttribute("myname", myname);
		request.setAttribute("mypwd", mypwd);
		
		return mapping.findForward("go");
	}
}
