JAX RS Client API拦截器

Question

当使用JAX RS Client API时，是否有办法通过拦截器向请求中添加标头，但不能通过显式设置标头：

Client client = ClientBuilder.newClient();
Response response = client.target("someUrl").path("somePath").request().get();

以AOP方式

Answer 1

创建ClientRequestFilter：

@Provider
public class MyClientRequestFilter implements ClientRequestFilter {

    @Override
    public void filter(ClientRequestContext requestContext) throws IOException {
        requestContext.getHeaders().add("Authorization", "value");
    }
}

并在Client：

中注册

Client client = ClientBuilder.newClient().register(MyClientRequestFilter.class);
