关于Http请求Cookie问题

在Http请求中,很多时候我们要设置Cookie和获取返回的Cookie,在这个问题上踩了一个很大的坑,主要是两个问题:

  1.不能获取到重定向返回的Cookie;

  2.两次请求返回的Cookie是相同的;

(接口是苏宁登录的接口,是用ids_r_me兑换authId的,这是单点登录常见的方式)后来我花了一点时间把几种不同的包中的坑总结一下:

第一个:apache下在httpclient

        <dependency>
            <groupId>org.apache.httpcomponents</groupId>
            <artifactId>httpclient</artifactId>
            <version>4.5.6</version>
        </dependency>

这个包在获取重定向Cookie时,会存在丢失Cookie的情况,这个包没有提供获取Cookie的借口方法,只能是通过Header获取Cookie和Set-Cookie获取返回的Cookie,用这个包发送Http请求好像没有存储重定向的Cookie,过程中肯定是有用到的,但是没有对外提供获取Cookie的接口,代码如下:

 1     /**
 2      * apache httpclient 4.5.6 test redirect Cookie
 3      */
 4     @Test
 5     public void Test_2() throws IOException {
 6         List<String> list = new ArrayList();
 7         list.add("NjIyMDY5MDk1M19CUk9XU0VSXz**********************************18wXzQ2OWM1ZjI3 NDdjN2RmYzRiZWI3Njg3MDllNzI3MmFj");
 8         list.add("NzEwNDIyNjQwN19CUk9XU0VSXz**********************************M18wX2JiZWQ5YmVkMjJiOTAyZDNjYmNkZTk4NGM0NmFiYmMz");
 9         String url = "https://passport.suning.com/ids/login?service=https%3A%2F%2Fmy.suning.com%2Fmsi-web%2Fauth%3FtargetUrl%3Dhttps%253A%252F%252Floginst.suning.com%252FauthStatus%253F_%253D1540179466121%2526callback%253DZepto1540179465802";
10 
11         for (String token : list) {
12             HttpClientBuilder httpClientBuilder = HttpClientBuilder.create();
13             CloseableHttpClient httpClient = httpClientBuilder.build();
14             HttpGet httpGet = new HttpGet(url);
15             httpGet.setHeader("Cookie", "ids_r_me=" + token);
16             CloseableHttpResponse response = httpClient.execute(httpGet);
17             org.apache.http.Header[] headers = response.getAllHeaders();
18             for (org.apache.http.Header header : headers) {
19                 System.out.println(header.getName() + "=" + header.getValue());
20             }
21             System.out.println(EntityUtils.toString(response.getEntity()) );
22         }
23     }

因为没有找到获取Cookie的接口,所以打印了所有的header。

第二个:hutool

        <dependency>
            <groupId>cn.hutool</groupId>
            <artifactId>hutool-all</artifactId>
            <version>4.2.1</version>
        </dependency>

这个包默认是可以获取Cookie的,但是开始遇到的问题是,第二次请求时获取的Cookie和第一次一样,因为这个包中的cookieManager是一个静态变量,但是第二次请求应该会覆盖掉才对,具体为什么不回覆盖没有再深追,后来找到了它提供的一个清空cookieManager中cookieStore的方法,问题就解决了。两次请求获取的是正常的Cookie。代码如下:

 1     /**
 2      * Hutool 4.2.1 test redirect Cookie
 3      */
 4     @Test
 5     public void Test_1() {
 6         List<String> list = new ArrayList();
 7         list.add("NjIyMDY5MDk1M19CUk9XU0VSXz**********************************18wXzQ2OWM1ZjI3 NDdjN2RmYzRiZWI3Njg3MDllNzI3MmFj");
 8         list.add("NzEwNDIyNjQwN19CUk9XU0VSXz**********************************M18wX2JiZWQ5YmVkMjJiOTAyZDNjYmNkZTk4NGM0NmFiYmMz");
 9         String url = "https://passport.suning.com/ids/login?service=https%3A%2F%2Fmy.suning.com%2Fmsi-web%2Fauth%3FtargetUrl%3Dhttps%253A%252F%252Floginst.suning.com%252FauthStatus%253F_%253D1540179466121%2526callback%253DZepto1540179465802";
10         for (String token : list) {
11 
12             HttpRequest request = HttpUtil.createGet(url);
13             Map header = new HashMap();
14             header.put("Cookie", "ids_r_me=" + token);
15             request = request.addHeaders(header);
16 
17             HttpResponse response = request.execute();
18 
19             List<HttpCookie> cookieList = response.getCookies();
20             System.out.println("Cookie:");
21             for (HttpCookie cookie : cookieList) {
22                 System.out.println(cookie.getName() + "=" + cookie.getValue());
23             }
24             HttpRequest.getCookieManager().getCookieStore().removeAll();
25         }
26     }

其中第24行是清除本次请求中的Cookie,如果放在response.getCookies()之前,就不能获取到Cookie了,所以应该是获取到Cookie后,清除本次请求的Cookie。

第三个:commons-httpclient

        <dependency>
            <groupId>commons-httpclient</groupId>
            <artifactId>commons-httpclient</artifactId>
            <version>3.1</version>
        </dependency>

这个包发送请求返回的有点奇怪,但是习惯了感觉好像也挺合理,代码如下:

 1     /**
 2      * commons-httpclient 3.1 test redirect Cookie
 3      *
 4      * @throws IOException
 5      */
 6     @Test
 7     public void Test_3() throws IOException {
 8         List<String> list = new ArrayList();
 9         list.add("NjIyMDY5MDk1M19CUk9XU0VSXz**********************************18wXzQ2OWM1ZjI3 NDdjN2RmYzRiZWI3Njg3MDllNzI3MmFj");
10         list.add("NzEwNDIyNjQwN19CUk9XU0VSXz**********************************M18wX2JiZWQ5YmVkMjJiOTAyZDNjYmNkZTk4NGM0NmFiYmMz");
11         String url = "https://passport.suning.com/ids/login?service=https%3A%2F%2Fmy.suning.com%2Fmsi-web%2Fauth%3FtargetUrl%3Dhttps%253A%252F%252Floginst.suning.com%252FauthStatus%253F_%253D1540179466121%2526callback%253DZepto1540179465802";
12         for (String token : list) {
13             HttpClient httpClient = new HttpClient();
14             GetMethod getMethod = new GetMethod(url);
15 
16             getMethod.setRequestHeader(new Header("Cookie", "ids_r_me=" + token));
17             Integer state = httpClient.executeMethod(getMethod);
18             Cookie[] cookieArray = httpClient.getState().getCookies();
19 for (Cookie cookie : cookieArray) { 20 System.out.println(cookie.getName() + "=" + cookie.getValue()); 21 } 22 System.out.println("responseBody:"+getMethod.getResponseBodyAsString()); 23 } 24 }

其中第17行返回的是本次请求的状态码,第22行是获取本次请求返回内容。
