# Jersey - 如何在 REST API 響應中設置 Cookie > 原文： [https://howtodoinjava.com/jersey/jersey-how-to-set-cookie-in-rest-api-response/](https://howtodoinjava.com/jersey/jersey-how-to-set-cookie-in-rest-api-response/) 在此示例中，我們將學習**為 Jersey REST API** 發送的 HTTP 響應設置 cookie。 本示例利用`javax.ws.rs.core.Response`將 Cookie 設置為發送到 REST 客戶端的 REST 響應中。 ## 設置 Cookie 語法 要在 REST API 響應中設置 Cookie，請獲取`Response`參考并使用其`cookie()`方法。 ```java Response.ok().entity(list).cookie(new NewCookie("cookieResponse", "cookieValueInReturn")).build(); ``` ## Rest API 示例代碼 我在下面編寫了 REST API 進行測試。 ```java @GET @Produces(MediaType.APPLICATION_JSON) @Consumes(MediaType.APPLICATION_JSON) public Response getAllEployees() { Employees list = new Employees(); list.setEmployeeList(new ArrayList<Employee>()); list.getEmployeeList().add(new Employee(1, "Lokesh Gupta")); list.getEmployeeList().add(new Employee(2, "Alex Kolenchiskey")); list.getEmployeeList().add(new Employee(3, "David Kameron")); return Response.ok().entity(list).cookie(new NewCookie("cookieResponse", "cookieValueInReturn")).build(); } ``` ## 演示 現在，使用 Jersey 客戶端代碼在 REST API 之上進行調用。 ```java public static void main(String[] args) { Client client = ClientBuilder.newClient( new ClientConfig().register( LoggingFilter.class ) ); WebTarget webTarget = client.target("http://localhost:8080/JerseyDemos/rest").path("employees"); Invocation.Builder invocationBuilder = webTarget.request(MediaType.APPLICATION_JSON); Response response = invocationBuilder.get(); Employees employees = response.readEntity(Employees.class); List<Employee> listOfEmployees = employees.getEmployeeList(); System.out.println(response.getCookies()); System.out.println(response.getStatus()); System.out.println(Arrays.toString( listOfEmployees.toArray(new Employee[listOfEmployees.size()]) )); } ``` ```java Output: {cookieResponse=cookieResponse=cookieValueInReturn;Version=1} 200 [Employee [id=1, name=Lokesh Gupta], Employee [id=2, name=Alex Kolenchiskey], Employee [id=3, name=David Kameron]] ``` **祝您學習愉快！**
