一、使用HttpURLConnection向服务器发送get请求

1、向服务器发送get请求

@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);     }

2、从服务器读取数据    

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

            

               

二、使用HttpURLConnection向服务器发送post请求

1、向服务器发送post请求

@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");         }     }

                

2、从服务器读取数据   

//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");
