  DefaultHttpClient 用 CloseableHttpClient

  HttpResponse 用 CloseableHttpResponse

  官方新api的样例

  Get方法：

      CloseableHttpClient httpclient = HttpClients.createDefault();
      HttpGet httpGet = new HttpGet("http://targethost/homepage");
      CloseableHttpResponse response1 = httpclient.execute(httpGet);
      // The underlying HTTP connection is still held by the response object
      // to allow the response content to be streamed directly from the network socket.
      // In order to ensure correct deallocation of system resources
      // the user MUST either fully consume the response content  or abort request
      // execution by calling CloseableHttpResponse#close().
  
      try {
          System.out.println(response1.getStatusLine());
          HttpEntity entity1 = response1.getEntity();
          // do something useful with the response body
          // and ensure it is fully consumed
          EntityUtils.consume(entity1);
      } finally {
          response1.close();
      }

  
  

  Post方法：

        HttpPost httpPost = new HttpPost("http://targethost/login");
      //拼接参数
      List <NameValuePair> nvps = new ArrayList <NameValuePair>();
      nvps.add(new BasicNameValuePair("username", "vip"));
      nvps.add(new BasicNameValuePair("password", "secret"));
      httpPost.setEntity(new UrlEncodedFormEntity(nvps));
      CloseableHttpResponse response2 = httpclient.execute(httpPost);
  
      try {
          System.out.println(response2.getStatusLine());
          HttpEntity entity2 = response2.getEntity();
          // do something useful with the response body
          // and ensure it is fully consumed
          //消耗掉response
          EntityUtils.consume(entity2);
      } finally {
          response2.close();
      }
