1. Overview<\/h2>\n
<\/div>\n

In this short tutorial, we’ll see how to get cookies from the Apache HttpClient response.\u00a0<\/em><\/p>\n

First, we’ll show how to send a custom cookie with an HttpClient<\/em> request. Then, we’ll see how to get it from the response.<\/p>\n

Please note that the code examples presented here are based on HttpClient 4.3.x and above, <\/strong>so they won’t work on older versions of the API.<\/p>\n

2. Sending Cookies in the Request<\/h2>\n
<\/div>\n

Before we can get our cookie from the response, we’ll need to create it and send it in a request:<\/p>\n

BasicCookieStore cookieStore = new BasicCookieStore();\r\nBasicClientCookie cookie = new BasicClientCookie(\"custom_cookie\", \"test_value\");\r\ncookie.setDomain(\"baeldung.com\");\r\ncookie.setPath(\"\/\");\r\ncookieStore.addCookie(cookie);\r\nHttpClientContext context = HttpClientContext.create();\r\ncontext.setAttribute(HttpClientContext.COOKIE_STORE, cookieStore);\r\ntry (CloseableHttpClient httpClient = HttpClients.createDefault()) {\r\n    try (CloseableHttpResponse response = httpClient.execute(new HttpGet(\"http:\/\/www.baeldung.com\/\"), context)) {\r\n        \/\/do something with the response\r\n    }\r\n}<\/code><\/pre>\n
First, we create a basic cookie store and a basic cookie<\/a> with the name custom_cookie<\/em> and value test_value<\/em>. Then, we create an HttpClientContext<\/em> instance that will hold the cookie store. Finally, we pass the created context as an argument to the execute()<\/em> method.<\/p>\n
3. Accessing Cookies<\/h2>\n
<\/div>\n
Now that we’ve sent a custom cookie in a request, let’s see how to read it from the response:<\/p>\n
HttpClientContext context = HttpClientContext.create();\r\ncontext.setAttribute(HttpClientContext.COOKIE_STORE, createCustomCookieStore());\r\ntry (CloseableHttpClient httpClient = HttpClients.createDefault()) {\r\n    try (CloseableHttpResponse response = httpClient.execute(new HttpGet(SAMPLE_URL), context)) {\r\n        CookieStore cookieStore = context.getCookieStore();\r\n        Cookie customCookie = cookieStore.getCookies()\r\n          .stream()\r\n          .peek(cookie -> log.info(\"cookie name:{}\", cookie.getName()))\r\n          .filter(cookie -> \"custom_cookie\".equals(cookie.getName()))\r\n          .findFirst()\r\n          .orElseThrow(IllegalStateException::new);\r\n          assertEquals(\"test_value\", customCookie.getValue());\r\n    }\r\n}\r\n<\/code><\/pre>\n
To get our custom cookie from the response, we must first get the cookie store from the context<\/strong>. Then, we use the getCookies <\/em>method to get the cookies list. We can then make use of Java streams<\/a>\u00a0to iterate over it and search for our cookie. Additionally, we log all cookie names from the store:<\/p>\n
[main] INFO  c.b.h.c.HttpClientGettingCookieValueTest - cookie name:__cfduid\r\n[main] INFO  c.b.h.c.HttpClientGettingCookieValueTest - cookie name:custom_cookie<\/code><\/pre>\n
4. Conclusion<\/h2>\n
<\/div>\n
In this article, we learned how to get cookies from the Apache HttpClient response.<\/p>\n
As always, the code is available over on GitHub<\/a>.<\/p>\n
