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
    //URL?
//     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();
    }
   }
