Android通过http协议数据交互的两种方式

方式一：HttpPost（import org.apache.http.client.methods.HttpPost）

private Button button1, button2, button3;private TextView textView1;button1.setOnClickListener(new Button.OnClickListener() {@Overridepublic void onClick(View arg0) {// TODO Auto-generated method stub// URLַ// String uriAPI =// "http://www.dubblogs.cc:8751/Android/Test/API/Post/index.php";String uriAPI = "http://172.20.0.206:8082//TestServelt/login.do";/* 建立HTTP Post连线 */HttpPost httpRequest = new HttpPost(uriAPI);// Post运作传送变数必须用NameValuePair[]阵列储存// 传参数 服务端获取的方法为request.getParameter("name")List<NameValuePair> params = new ArrayList<NameValuePair>();params.add(new BasicNameValuePair("name", "this is post"));try {// 发出HTTP requesthttpRequest.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));// 取得HTTP responseHttpResponse httpResponse = new DefaultHttpClient().execute(httpRequest);// 若状态码为200 okif (httpResponse.getStatusLine().getStatusCode() == 200) {// 取出回应字串String strResult = EntityUtils.toString(httpResponse.getEntity());textView1.setText(strResult);} else {textView1.setText("Error Response" + httpResponse.getStatusLine().toString());}} catch (ClientProtocolException e) {textView1.setText(e.getMessage().toString());e.printStackTrace();} catch (UnsupportedEncodingException e) {textView1.setText(e.getMessage().toString());e.printStackTrace();} catch (IOException e) {textView1.setText(e.getMessage().toString());e.printStackTrace();}}});

方式二：HttpURLConnection、URL(import java.net.HttpURLConnection;import java.net.URL;import java.net.URLEncoder;)

private void httpUrlConnection() {try {String pathUrl = "http://172.20.0.206:8082/TestServelt/login.do";// 建立连接URL url = new URL(pathUrl);HttpURLConnection httpConn = (HttpURLConnection) url.openConnection();// //设置连接属性httpConn.setDoOutput(true);// 使用 URL 连接进行输出httpConn.setDoInput(true);// 使用 URL 连接进行输入httpConn.setUseCaches(false);// 忽略缓存httpConn.setRequestMethod("POST");// 设置URL请求方法String requestString = "客服端要以以流方式发送到服务端的数据...";// 设置请求属性// 获得数据字节数据，请求数据流的编码，必须和下面服务器端处理请求流的编码一致byte[] requestStringBytes = requestString.getBytes(ENCODING_UTF_8);httpConn.setRequestProperty("Content-length", "" + requestStringBytes.length);httpConn.setRequestProperty("Content-Type", "application/octet-stream");httpConn.setRequestProperty("Connection", "Keep-Alive");// 维持长连接httpConn.setRequestProperty("Charset", "UTF-8");//String name = URLEncoder.encode("黄武艺", "utf-8");httpConn.setRequestProperty("NAME", name);// 建立输出流，并写入数据OutputStream outputStream = httpConn.getOutputStream();outputStream.write(requestStringBytes);outputStream.close();// 获得响应状态int responseCode = httpConn.getResponseCode();if (HttpURLConnection.HTTP_OK == responseCode) {// 连接成功// 当正确响应时处理数据StringBuffer sb = new StringBuffer();String readLine;BufferedReader responseReader;// 处理响应流，必须与服务器响应流输出的编码一致responseReader = new BufferedReader(new InputStreamReader(httpConn.getInputStream(), ENCODING_UTF_8));while ((readLine = responseReader.readLine()) != null) {sb.append(readLine).append("\n");}responseReader.close();tv.setText(sb.toString());}} catch (Exception ex) {ex.printStackTrace();}}

补充：

标准的http post传输方式，以上面为例子，如下：

requestStringBytes =“customerId=3461&nickName=黄&email=linafei1111@163.com&areaCode=0592&cityCode=350200&registerPhone=18906051120”服务端通过getParamer("customerId")获取。

如果把参数值放在URL，例如http://172.20.0.206:8082/TestServelt/login.do?customerId=3461&nickName=黄&email=linafei1111@163.com&areaCode=0592&cityCode=350200&registerPhone=18906051120

虽然是以post方式传输，但是实际上还是以get方式提交
