Json传值

一、POST传值方法

public static String SendUlr(String requestUrl,String xml) {
	   	 String responseStr="";
	       try {
	           URL url = new URL(requestUrl);
	           HttpURLConnection urlConnection = (HttpURLConnection)url.openConnection();
	           urlConnection.setDoOutput(true);
	           urlConnection.setDoInput(true);
	           urlConnection.setRequestMethod("POST");
	           urlConnection.setUseCaches(false); 
	           urlConnection.setInstanceFollowRedirects(true);
	           urlConnection.setRequestProperty("Content-Type","application/x-www-form-urlencoded");
	           urlConnection.setRequestProperty("Charset", "UTF-8"); 
	           urlConnection.connect();
	           DataOutputStream out = new DataOutputStream(urlConnection.getOutputStream());
	           String params= xml;       
	           out.write(params.getBytes("UTF-8"));
	         /*  out.writeBytes(params);*/
	           out.flush();
	           out.close(); 
	           BufferedReader reader = new BufferedReader(new InputStreamReader(urlConnection.getInputStream(),"UTF-8"));
	           String line;
	           while ((line = reader.readLine()) != null){
	               responseStr+=line;
	           }
	           reader.close();
	           urlConnection.disconnect();
	       }catch (MalformedURLException e) {
	           // TODO Auto-generated catch block
	           e.printStackTrace();
	       } catch (ProtocolException e) {
	           // TODO Auto-generated catch block
	           e.printStackTrace();
	       } catch (IOException e) {
	           // TODO Auto-generated catch block
	           e.printStackTrace();
	       }
	       return responseStr;
	   }
