有没有一种方法可以将cookie传递给使用相同Client对象的所有请求？ 现在我必须将cookie传递给每个这样的请求：
final Client client = ClientBuilder.newClient(clientConfig);
UriBuilder authenticate_url = UriBuilder.fromUri("xxxxxxxxx/authenticate");
WebTarget webTarget = client.target(authenticate_url);
Invocation.Builder invocationBuilder = webTarget.request(MediaType.APPLICATION_XML);
Response response = invocationBuilder.get();
Map<String, NewCookie> cookies = response.getCookies(); //store cookies
webTarget = client.target(other_url);
invocationBuilder = webTarget.request(MediaType.APPLICATION_XML).cookie(cookies.get("KEY"));
response = invocationBuilder.get(); //works
invocationBuilder = webTarget.request(MediaType.APPLICATION_XML);
response = invocationBuilder.get(); //does not work
答案 0 :(得分：0)
你可以像这样使用@Context

或者您可以使用@GET
public String get(@Context HttpHeaders hh)
{
MultivaluedMap<String, String> headerParams = hh.getRequestHeaders();
Map<String, Cookie> pathParams = hh.getCookies();
}
这样的注释
@CookieParam<强>更新
在您的调用构建器中添加
@POST
public void post(@CookieParam("<parmeter name>") CookieParameter ckparameter) {
...
}
