HttpClient详细应用请参考官方api文档：http://hc.apache.org/httpcomponents-client-4.5.x/httpclient/apidocs/index.html
1.使用httpclient进行接口测试,所需jar包如下：httpclient.jar、 httpcore.jar、 commons-logging.jar
2.使用JSONObject插件处理响应数据
所需的6个JAR包：json-lib.jar、commons-beanutils.jar、commons-collections.jar、ezmorph.jar、commons-logging.jar、commons-lang.jar
3.使用正则表达式匹配提取响应数据
1 public class UserApiTest {
2 private static CloseableHttpClient httpClient = null;

4 @BeforeClass
5 public static void setUp(){
6 httpClient = HttpClients.createDefault(); //创建httpClient
7 }

10 public static void terDown() throws IOException{
11 httpClient.close();
