#### 1.首先配置好测试用的mock接口 ####

[
    {
        "description":"这是一个带cookies信息的get请求",
        "request":{ "uri":"/getcookies", "method":"get" },
        "response":{ "cookies":{ "login":"true" }, "text":"获得cookies信息成功" } },
      {
        "description":"这是一个带cookies信息的post请求",
        "request":{ "uri":"/post/with/cookies", "method":"post", "cookies":{ "login":"true" }, "json":{ "name":"lyn", "age":"18" } },
        "response":{ "status":200, "json":{ "lyn":"lyn", "code":"1" } } }
    ]

我们要做的是从/getcookies接口中获取”login”:”true”的cookies信息，然后携带该信息去访问/post/with/cookies接口

#### 2.全局变量配置url信息 ####

resource目录下新建application.properties文件，文件内配置访问接口的url和路径

test.url=http://localhost:8899
    test.getcookies.uri=/getcookies
    test.post.with.cookies=/post/with/cookies

#### 3.测试准备 ####

从配置文件中读取url，以及准备储存cookies信息的变量

private String url;
    private ResourceBundle bundle;
    
    //用来存取cookies信息的变量
    private CookieStore store;
    
    @BeforeTest
    public void beforeTest(){
         bundle = ResourceBundle.getBundle("application",Locale.CHINA);
         url = bundle.getString("test.url");
        }

#### 4.访问/getcookies接口以获取cookies信息 ####

@Test
    public void testGetCookies() throws IOException {
    
            //从配置文件中，提取并拼接url
            String uri = bundle.getString("test.getcookies.uri");
            String testUrl = this.url+uri;
    
            //获取body
            String result;
            HttpGet get = new HttpGet(testUrl);
            DefaultHttpClient client = new DefaultHttpClient();
            HttpResponse response = client.execute(get);
            result = EntityUtils.toString(response.getEntity(),"utf-8");
            System.out.println(result);
    
            //获取cookies信息
            this.store = client.getCookieStore();
            List<Cookie> cookieList = store.getCookies();
            for (Cookie cookie : cookieList){
                String name =cookie.getName();
                String value = cookie.getValue();
                System.out.println("访问/getcookies接口成功，cookie name = "+name+", cookie value = "+value);
            }
        }

#### 5.携带由步骤4中获取的cookies信息访问/post/with/cookies接口 ####

@Test(dependsOnMethods = {
       "testGetCookies"})
        public void testPostCookies() throws IOException {
    
            //从配置文件中，提取并拼接url
            String uri = bundle.getString("test.post.with.cookies");
            String testUrl = this.url+uri;
    
            //声明一个Client对象，用来进行方法的执行
            DefaultHttpClient client = new DefaultHttpClient();
    
            //声明一个方法，这个方法就是post方法
            HttpPost post = new HttpPost(testUrl);
    
            //添加参数
            JSONObject param = new JSONObject();
            param.put("name","lyn");
            param.put("age","18");
    
            //设置header信息
            post.setHeader("content-type","application/json");
    
            //将参数信息添加到方法中
            StringEntity entity = new StringEntity(param.toString(),"utf-8");
            post.setEntity(entity);
    
            //声明一个对象来进行相应结果的存储
            String result;
    
            //设置cookies信息
            client.setCookieStore(this.store);
    
            //执行post方法
            HttpResponse response = client.execute(post);
    
            //获取相应结果
            result = EntityUtils.toString(response.getEntity(),"utf-8");
            System.out.println(result);
    
            //将返回的相应结果字符串转化为json对象
            JSONObject resultJson = new JSONObject(result);
    
            //获取到结果值
            String lyn = (String)resultJson.get("lyn");
            String status = (String) resultJson.get("code");
            //具体判断返回结果的值
            Assert.assertEquals("lyn",lyn);
            Assert.assertEquals("1",status);
    
        }
