客户端post请求



public void setPost() {

        PostMethod post = new PostMethod(

                "http://localhost:9999/t/retrieve");

        Util des = new Util();

        String xml = "<?xml version=\"1.0\" encoding=\"utf-8\"?><request><sid value=\"100006\" /><barcodeid value=\"1325\" /><terminalid value=\"7001\" /></request>";

        try {

            byte[] s = des.encryptData(xml, "MGI0ZmZ6".getBytes());//将字符串进行DES加密

            System.out.println(s.length);//打印出来136

            ByteArrayInputStream tInputStringStream = new

                   ByteArrayInputStream(s);

            post.setRequestBody(tInputStringStream);

            post.setRequestHeader("Request-Type", "noticeVerify");

            post.setRequestHeader("Content-length", "" + s.length);//136

            post.setRequestHeader("Content-type", "application/vbs.xml");

            HttpClient httpclient = new HttpClient();

            int result = httpclient.executeMethod(post);

            System.out.println("Response status code: " + result);

            System.out.println("Response body: ");

            System.out.println(post.getResponseBodyAsString());

            post.releaseConnection();

        } catch (Exception ex) {

            System.out.println(ex);

        }



    }

客户端取数据的时候是用一个servlet



public void doPost(HttpServletRequest request, HttpServletResponse response) throws

            ServletException, IOException {

        response.setContentType(CONTENT_TYPE);

        PrintWriter out = response.getWriter();

        StringBuilder sb = null;

        try {

            BufferedReader br = new BufferedReader(new InputStreamReader((

                    ServletInputStream) request.getInputStream()));

            String line = null;

            sb = new StringBuilder();

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

                sb.append(line);

            }

            br.close();

        } catch (IOException ex2) {

            System.out.println(ex2);

        }

        String e = sb.toString();

        Util des = new Util();

        System.out.println(e.getBytes().length);//134 

 



    }
