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");
