Android通过http协议POST传输方式

Android通过http协议POST传输方式如下：

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

代码如下：

private Button button1,button2,button3;

 private TextView textView1;

 button1.setOnClickListener(new Button.OnClickListener(){         

   @Override

   public 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 request

     httpRequest.setEntity(new UrlEncodedFormEntity(params,HTTP.UTF_8));

     //取得HTTP response

     HttpResponse httpResponse=new DefaultHttpClient().execute(httpRequest);

     

     //若状态码为200 ok 

     if(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®isterPhone=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®isterPhone=18906051120

虽然是以post方式传输，但是实际上还是以get方式提交
