Flex和Java交互的乱码解决方案

今天做Flex时碰到flex和java交互的乱码问题，使用HTTPService无论是从Flex端传到Java端，还是反过来都乱码。调查了半天，终于搞定了。
 
 
以下是解决方案：
 
 
1.Flex端传到Java端
 
Flex端:encodeURIComponent(comment.text)
使用encodeURIComponent把参数转换为 application/x-www-form-urlencoded 格式
 
Java端:URLDecoder.decode(comment, "utf-8")
对 x-www-form-urlencoded 字符串解码
 
2.Java端传到Flex端
 
 
 
 
 
HttpServletResponse response = ServletActionContext.getResponse();
PrintWriter out = response.getWriter();
response.setContentType("text/html;charset=utf-8");

out.println(doc.asXML());
out.flush();
out.close();

→

HttpServletResponse response = ServletActionContext.getResponse();
ServletOutputStream out = response.getOutputStream();
response.setContentType("text/html;charset=utf-8");

out.write(doc.asXML().getBytes("UTF-8"));
out.flush();
out.close();
