# Jersey - 如何在 REST API 响应中设置 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，我们将学习**为 Jersey REST API** 发送的 HTTP 响应设置 cookie。 本示例利用`javax.ws.rs.core.Response`将 Cookie 设置为发送到 REST 客户端的 REST 响应中。 ## 设置 Cookie 语法 要在 REST API 响应中设置 Cookie，请获取`Response`参考并使用其`cookie()`方法。 ```java Response.ok().entity(list).cookie(new NewCookie("cookieResponse", "cookieValueInReturn")).build(); ``` ## Rest API 示例代码 我在下面编写了 REST API 进行测试。 ```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 现在，使用 Jersey 客户端代码在 REST API 之上进行调用。 ```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]] ``` **祝您学习愉快！**
