Android通過http協議POST傳輸方式

Android通過http協議POST傳輸方式

文章分類:移動開發

Android通過http協議POST傳輸方式如下：

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

代碼如下：

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連線*/
    HttpPost httpRequest =new HttpPost(uriAPI);
    //Post運作傳送變數必須用NameValuePair[]陣列儲存
    //傳參數 服務端擷取的方法為request.getParameter("name")
    List <NameValuePair> params=new ArrayList<NameValuePair>();
    params.add(new BasicNameValuePair("name","this is post"));
    try{
     
     
     //發出HTTP request
     httpRequest.setEntity(new UrlEncodedFormEntity(params,HTTP.UTF_8));
     //取得HTTP response
     HttpResponse httpResponse=new DefaultHttpClient().execute(httpRequest);
     
     //若狀態代碼為200 ok 
     if(httpResponse.getStatusLine().getStatusCode()==200){
      //取出回應字串
      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";
     //建立串連
     URL url=new URL(pathUrl);
     HttpURLConnection httpConn=(HttpURLConnection)url.openConnection();
     
     ////設定串連屬性
     httpConn.setDoOutput(true);//使用 URL 串連進行輸出
     httpConn.setDoInput(true);//使用 URL 串連進行輸入
     httpConn.setUseCaches(false);//忽略緩衝
     httpConn.setRequestMethod("POST");//設定URL要求方法
     String requestString = "客服端要以以流方式發送到服務端的資料...";
     
     //佈建要求屬性
    //獲得資料位元組資料，請求資料流的編碼，必須和下面伺服器端處理請求流的編碼一致
          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");// 維持長串連
          httpConn.setRequestProperty("Charset", "UTF-8");
          //
          String name=URLEncoder.encode("黃武藝","utf-8");
          httpConn.setRequestProperty("NAME", name);
          
          //建立輸出資料流，並寫入資料
          OutputStream outputStream = httpConn.getOutputStream();
          outputStream.write(requestStringBytes);
          outputStream.close();
         //獲得響應狀態
          int responseCode = httpConn.getResponseCode();
          if(HttpURLConnection.HTTP_OK == responseCode){//串連成功
           
           //當正確響應時處理資料
           StringBuffer sb = new StringBuffer();
              String readLine;
              BufferedReader responseReader;
             //處理響應流，必須與伺服器響應流輸出的編碼一致
              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();
    }
   }
