Flex HttpService中乱码的解决

文章分类:Flash编程

Flex与Strust2的交互中,乱码问题很是头痛,网上的解决方法也不系统,花了很长时间才解决~~~

 

Flex->Action

在flex前台将要传输的字符串编码:

UserRegisterDetailSave.request.address = encodeURIComponent(address.text);

 

address中的内容包含中文,就需要重新编码

 

后台需要增加一个编码的Filter:

 package  com.filter;

 import  java.io.IOException;

 import  javax.servlet.Filter;
 import  javax.servlet.FilterChain;
 import  javax.servlet.FilterConfig;
 import  javax.servlet.ServletException;
 import  javax.servlet.ServletRequest;
 import  javax.servlet.ServletResponse;

 public   class  EncodingFilter  implements  Filter{

     public   void  destroy()
     {

     }

     public   void  doFilter(ServletRequest request, ServletResponse response,
         FilterChain filterChain) throws  IOException, ServletException
     {
         request.setCharacterEncoding("utf-8" );
         response.setCharacterEncoding("utf-8" );

         filterChain.doFilter(request, response);
     }

     public   void  init(FilterConfig arg0)  throws  ServletException {
         // TODO Auto-generated method stub

     }
 }

package com.filter;

import java.io.IOException;

import javax.servlet.Filter;
import javax.servlet.FilterChain;
import javax.servlet.FilterConfig;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;

public class EncodingFilter implements Filter{

	public void destroy()
	{
		
	}
	
	public void doFilter(ServletRequest request, ServletResponse response,
		FilterChain filterChain) throws IOException, ServletException
	{
		request.setCharacterEncoding("utf-8");
		response.setCharacterEncoding("utf-8");
		
		filterChain.doFilter(request, response);
	}

	public void init(FilterConfig arg0) throws ServletException {
		// TODO Auto-generated method stub
	
	}
}

 

 

这个Filter将请求编码为"utf-8"的形式,这样才能进行下一步解码.在Action中,需要用到值中包含中文的属性时,用 URLDecoder.decode(address, "utf-8")进行解码,解码前后address都是String类型.如果还是不行的话,检查一下前台界面是不是 有:initialize="flash.system.System.useCodePage=true"的标记,有的话改成false.

 

Action->Flex

这个很方便,添加两行代码至Action末端:

HttpServletResponse response = ServletActionContext.getResponse();
  response.setCharacterEncoding("utf-8");

 

最后就是通过HttpService获取远程Xml了,这个更方便了,将页面Application标签里添加:

initialize="flash.system.System.useCodePage=true"

 

上面的方法全是项目中自己遇到然后解决了的,如果没有用的话那只能深感无奈了~~~
