Android通过http协议POST传输方式

Android通过http协议POST传输方式http://chunpeng.iteye.com/blog/631972Android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();    }   }
