JAVA_http的post请求 实例

实例一：

String uriAPI = "http://192.168.1.100:8080/test/test.jsp"; //这是我测试的本地,大家可以随意改
        /*建立HTTPost对象*/
        HttpPost httpRequest = new HttpPost(uriAPI);
        /*
         * NameValuePair实现请求参数的封装
        */
        List <NameValuePair> params = new ArrayList <NameValuePair>();
        params.add(new BasicNameValuePair("u", "沈大海"));
        params.add(new BasicNameValuePair("p", "123"));
        try
        {
          /* 添加请求参数到请求对象*/
          httpRequest.setEntity(new UrlEncodedFormEntity(params, HTTP.UTF_8));
          /*发送请求并等待响应*/
          HttpResponse httpResponse = new DefaultHttpClient().execute(httpRequest);
          /*若状态码为200 ok*/
          if(httpResponse.getStatusLine().getStatusCode() == 200) 
          {
            /*读返回数据*/
            String strResult = EntityUtils.toString(httpResponse.getEntity());
            mTextView1.setText(strResult);
          }
          else
          {
            mTextView1.setText("Error Response: "+httpResponse.getStatusLine().toString());
          }
        }
        catch (ClientProtocolException e)
        { 
          mTextView1.setText(e.getMessage().toString());
          e.printStackTrace();
        }
        catch (IOException e)
        { 
          mTextView1.setText(e.getMessage().toString());
          e.printStackTrace();
        }
        catch (Exception e)
        { 
          mTextView1.setText(e.getMessage().toString());
          e.printStackTrace(); 
        }

实例二：
public void MyFunction{

HttpClient httpclient = new DefaultHttpClient();

//你的URL

  HttpPost httppost = new HttpPost("http://www.winu.cn/post_datas.php");

  try {

   List<NameValuePair> nameValuePairs = new ArrayList<NameValuePair>(2);

//Your DATA

   nameValuePairs.add(new BasicNameValuePair("id", "12345"));

   nameValuePairs.add(new BasicNameValuePair("stringdata", "eoeAndroid.com is Cool!"));

   httppost.setEntity(new UrlEncodedFormEntity(nameValuePairs));

   HttpResponse response;

   response=httpclient.execute(httppost);

  } catch (ClientProtocolException e) {

   // TODO Auto-generated catch block

   e.printStackTrace();

  } catch (IOException e) {

   // TODO Auto-generated catch block

   e.printStackTrace();

  }

}
