HttpClient獲取cookies信息

1.首先配置好測試用的mock接口

[
  {
    "description": "模擬會返回cookies的get請求",
    "request": {
      "uri": "/getcookies",
      "method": "get"
    },
    "response": {
      "cookies": {
        "login": "flase"
      },
      "json": {
        "text": "這是一個會返回cookies信息的get請求"
      }
    }
  },
  {
    "description": "模擬一個帶cookies的get請求",
    "request": {
      "uri": "/get/with/cookies",
      "method": "get",
      "cookies": {
        "login": "true",
        "token": "test"
      }
    },
    "response": {
      "json": {
        "text": "這是一個需要攜帶cookies信息才能訪問的get請求"
      }
    }
  }

]

2.在Terminal裏執行命令，啓動mock

java -jar -Dfile.encoding=UTF-8 ./moco-runner-0.11.0-standalone.jar http -p 8890 -c startupGet.json

3.在httpclient調用方法裏獲取cookies信息

/**
 * http請求方法的封裝
 */
public class RestClient {
      CookieStore store;

    /**
     * 不帶請求頭的get方法封裝
     * @param url
     * @return 返回響應對象
     * @throws ClientProtocolException
     * @throws IOException
     */

    public CloseableHttpResponse get(String url) throws ClientProtocolException, IOException {

        //創建一個可關閉的HttpClient對象
        CloseableHttpClient httpclient = HttpClients.createDefault();

        // 設置cookies信息
        store = new BasicCookieStore();
        httpclient = HttpClients.custom().setDefaultCookieStore(store).build();
        //創建一個Httpget的請求對象
        HttpGet httpget = new HttpGet(url);
        //執行請求,相當於postman上點擊發送按鈕，然後賦值給HttpResponse對象接收
        CloseableHttpResponse httpResponse = httpclient.execute(httpget);

        // 讀取cookie信息
        List<Cookie> cookielist = store.getCookies();
        for (Cookie cookie : cookielist) {
            String name = cookie.getName();
            String value = cookie.getValue();
            System.out.println("cookie:name=" + name + ";value=" + value);
        }
        return httpResponse;

    }
}    

4.在httpclient調用方法裏攜帶cookies訪問信息

    /**
     * 不帶請求頭帶cookies信息的get方法封裝
     * @param url
     * @param cookieList,存放多個cookies信息
     * @return 返回響應對象
     * @throws ClientProtocolException
     * @throws IOException
     */

    public CloseableHttpResponse get(String url,ArrayList cookieList) throws ClientProtocolException, IOException {

        // 設置cookies信息
        store = new BasicCookieStore();
        for (Object x:
                cookieList) {
            store.addCookie((Cookie) x);
        }
        CloseableHttpClient httpclient = HttpClients.custom().setDefaultCookieStore(store).build();

        //創建一個Httpget的請求對象
        HttpGet httpget = new HttpGet(url);
        //執行請求,相當於postman上點擊發送按鈕，然後賦值給HttpResponse對象接收
        CloseableHttpResponse httpResponse = httpclient.execute(httpget);

        return httpResponse;

    }

5.調用返回cookies信息的接口和需要攜帶cookies信息才能訪問的接口

public class Case2 {

    public static void main(String[] args){

    @Test
    public void test3() throws IOException {
        String url;
        url = "http://127.0.0.1:8890/getcookies";
        RestClient restClient = new RestClient();

        CloseableHttpResponse closeableHttpResponse = restClient.get(url);
        JSONObject responseJson = restClient.getResponseJson(closeableHttpResponse);
        System.out.println("responseJson:" + responseJson);
    }

    @Test
    public void test4() throws IOException {
        String url;
        url = "http://127.0.0.1:8890/get/with/cookies";
        //添加cookies信息
        BasicClientCookie cookie1 = new BasicClientCookie("login","true");
        cookie1.setVersion(0);
        cookie1.setDomain("127.0.0.1");
        cookie1.setPath("/get/with/cookies");
        //添加cookies信息
        BasicClientCookie cookie2 = new BasicClientCookie("token","test");
        cookie2.setVersion(0);
        cookie2.setDomain("127.0.0.1");
        cookie2.setPath("/get/with/cookies");

        ArrayList cookieList = new ArrayList();
        cookieList.add(cookie1);
        cookieList.add(cookie2);

        RestClient restClient = new RestClient();
        CloseableHttpResponse closeableHttpResponse = restClient.get(url,cookieList);
        JSONObject responseJson = restClient.getResponseJson(closeableHttpResponse);
        System.out.println("responseJson:" + responseJson);
    }

}

執行結果：
