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()==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("
");  
                  }  
                  responseReader.close();  
                  tv.setText(sb.toString());  
              }  
        }catch(Exception ex){  
         ex.printStackTrace();  
        }  
       }
