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

一、使用HttpURLConnection向服务器发送get请求

1、向服务器发送get请求

    @Testpublicvoid 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

    @Testpublicvoid 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");
