一般POST或GET中的数据的都是key=value键值对形式。其实POST可以更强大，我们可以直接POST一段XML。

发送的客户端代码：

//xml参数为需要发送的xml格式的字符串

   public static String connectServer(String xml) {

      String returnMsg = “”;

      String urlStr=”http://localhost/external.action”;

        try {

            URL url = new URL(urlStr);

            URLConnection con = url.openConnection();

            con.setDoOutput(true);

            con.setRequestProperty(“Pragma:”, “no-cache”);

            con.setRequestProperty(“Cache-Control”, “no-cache”);

            con.setRequestProperty(“Content-Type”, “text/xml”);

            OutputStreamWriter out = new OutputStreamWriter(con

                    .getOutputStream(),”utf-8″);

            out.write(new String(xml.getBytes()));

            out.flush();

            out.close();

            BufferedReader br = new BufferedReader(new InputStreamReader(con

                    .getInputStream(),”utf-8″));

            String line = “”;

            for (line = br.readLine(); line != null; line = br.readLine()) {

                System.out.println(line);

                returnMsg =returnMsg + line;

            }

        } catch (MalformedURLException e) {

            e.printStackTrace();

        } catch (IOException e) {

            e.printStackTrace();

        }

      return returnMsg;

   }

服务器端的代码：

         //获取HTTP请求的输入流

           InputStream is;

         is = request.getInputStream();

           //已HTTP请求输入流建立一个BufferedReader对象

           BufferedReader br = new BufferedReader(new InputStreamReader(is,”UTF-8″));

           //读取HTTP请求内容

           String buffer = null;

           while ((buffer = br.readLine()) != null) {

           //在页面中显示读取到的请求参数

               sb.append(buffer);

           }

       //Sb就是接收到的xml字符串。
