android http协议post请求方式

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()==){
      //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();
        }
       }
