使用HttpURLConnection向服务器发送post和get请求(转)

    @Test
publicvoid sendSms() throws Exception{
 String message="货已发到";
 message=URLEncoder.encode(message, "UTF-8");
 System.out.println(message);
 String path ="http://localhost:8083/DS_Trade/mobile/sim!add.do?message="+message;
 URL url =new URL(path);
 HttpURLConnection conn = (HttpURLConnection)url.openConnection();
 conn.setConnectTimeout(5*1000);
 conn.setRequestMethod("GET");
 InputStream inStream = conn.getInputStream(); 
byte[] data = StreamTool.readInputStream(inStream);
 String result=new String(data, "UTF-8");
 System.out.println(result);
 }

String message=request.getParameter("message");

    @Test
publicvoid addByUrl() throws Exception{
 String encoding="UTF-8";
 String params="[{\"addTime\":\"2011-09-19 14:23:02\"[],\"iccid\":\"1111\",\"id\":0,\"imei\":\"2222\",\"imsi\":\"3333\",\"phoneType\":\"4444\",\"remark\":\"aaaa\",\"tel\":\"5555\"}]";
 String path ="http://localhost:8083/xxxx/xxx/sim!add.do";
byte[] data = params.getBytes(encoding);
 URL url =new URL(path);
 HttpURLConnection conn = (HttpURLConnection)url.openConnection();
 conn.setRequestMethod("POST");
 conn.setDoOutput(true);
//application/x-javascript text/xml->xml数据 application/x-javascript->json对象 application/x-www-form-urlencoded->表单数据
 conn.setRequestProperty("Content-Type", "application/x-javascript; charset="+ encoding);
 conn.setRequestProperty("Content-Length", String.valueOf(data.length));
 conn.setConnectTimeout(5*1000);
 OutputStream outStream = conn.getOutputStream();
 outStream.write(data);
 outStream.flush();
 outStream.close();
 System.out.println(conn.getResponseCode()); //响应代码 200表示成功
 if(conn.getResponseCode()==200){
InputStream inStream = conn.getInputStream();   
String result=new String(StreamTool.readInputStream(inStream), "UTF-8");
 }
 }

//获取post请求过来的数据
byte[] data=StreamTool.readInputStream(request.getInputStream());
//[{\"addTime\":\"2011-09-19 14:23:02\"[],\"iccid\":\"1111\",\"id\":0,\"imei\":\"2222\",\"imsi\":\"3333\",\"phoneType\":\"4444\",\"remark\":\"aaaa\",\"tel\":\"5555\"}]
 String json=new String(data, "UTF-8");
