Get request body in Quarkus Interceptor

Question

I have written an interceptor in Quarkus based application.

@AccessPolicy  //custom annotation
@Interceptor
public class PolicyInterceptor {
  
  @AroundInvoke
  Object authorize(InvocationContext context) throws Exception {

  HttpServerRequest request = ResteasyProviderFactory.getInstance().getContextData(HttpServerRequest.class);
  String tenantId = request.getHeader("tenant-id");
  //business logic here which needs request body
  return context.proceed();
}

There are some rest APIs which are annotated with @AccessPolicy and this interceptor is properly intercepting them. I am able to get header value from the request (request.getHeader("tenant-id")).

Somehow body is not available in the HttpServerRequest object.

PS: I can't use ContainerRequestFilter as I need InvocationContext for the business logic. Please suggest if there is any other way which gives me both request body and invocation context.

Answer 1

Using ContainerRequestFilter worked for me as I needed InvocationContext only to get the method name of the Rest API and it was available in the ContainerRequestContext.

String methodName = ((PostMatchContainerRequestContext) requestContext).getResourceMethod().getMethod().getName();
