第一步：封裝查詢引數，拼接url

String url = "www.baidu.com?name=liufei";

第二步：發出請求

 HttpClient client = new DefaultHttpClient();
 HttpGet request = new HttpGet(url);
 HttpResponse response = client.execute(request);

第三部：處理響應結果

               try {
			BufferedReader bufferedReader = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));
			StringBuffer result = new StringBuffer();
			String line = "";
			while ((line = bufferedReader.readLine()) != null) {
				result.append(line);
			}

			Logger.info(result.toString());
		} catch (Exception e) {
			Logger.info("查詢出錯：" + e.getMessage() + e);
			e.printStackTrace();
		}
