我想在客户来电之前和之后拦截请求。
假设:
Form formData = new Form();
formData.param("grant_type", "client_credentials");
List<Object> providers = new ArrayList();
providers.add(new GsonMessageBodyProvider());
providers.add(new RestLogger ()); <--doesn't work
WebClient client = WebClient.create("https://blah.com", providers);
// sets timeouts.
HTTPConduit conduit = WebClient.getConfig(client).getHttpConduit();
conduit.getClient().setReceiveTimeout(1000);
conduit.getClient().setConnectionTimeout(1000);
client.path("token.oauth2");
client.type(MediaType.APPLICATION_FORM_URLENCODED_TYPE).accept(MediaType.APPLICATION_JSON);
WebClient wc = WebClient.fromClient(client);// thread safe
BearerTokenResponse r = wc.post(formData, BearerTokenResponse.class);
System.out.println(ToStringBuilder.reflectionToString(r));
我写了一个这样的课程,我觉得它会起作用:
public class RestLogger implements ContainerRequestFilter, ContainerResponseFilter {
@Override
public void filter(ContainerRequestContext requestContext, ContainerResponseContext responseContext) throws IOException {
System.out.println("request");
}
@Override
public void filter(ContainerRequestContext requestContext) throws IOException {
System.out.println("response");
}
}
但它没有发射。有帮助吗?我在Storm集群中执行此操作,因此无法使用Annotations。我需要以编程方式挂钩。我使用3.1.10(最新)

要拦截客户端上的请求和响应,请使用ClientRequestFilter
和ClientResponseFilter
。
要拦截服务器端上的请求和响应,请使用ContainerRequestFilter
和ContainerResponseFilter
。
