Jersey - 如何在 REST API 响应中设置 Cookie

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/

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。

要在 REST API 响应中设置 Cookie，请获取Response参考并使用其cookie()方法。

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。

@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。

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()]) ));
}


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]]
