Rate Limit Response - I'd like to modify the body

[neskita]

spring-cloud-gateway/spring-cloud-gateway-core/src/main/java/org/springframework/cloud/gateway/filter/factory/RequestRateLimiterGatewayFilterFactory.java

Line 129 in 2231658

return exchange.getResponse().setComplete();

I'd like to customise the body when Rate Limit filter returns 429.

I can add the headers I want, but body is empty and I have a requirement to customise it.
I've tried other filter combinations, they work ok for other responses but it seems after this response is set to complete none of the filter / modifications are applied

Is there any workaround I could apply? Or any chance custom body is added any time soon to
org.springframework.cloud.gateway.filter.ratelimit.RateLimiter.Response ?

Thanks!

Not currently. Not quite sure how that would work right now.

me too

u just need to write a new GateWayFilterFactory,maybe code like that:

DataBuffer buffer = exchange.getResponse().bufferFactory().wrap(bytes);
return exchange.getResponse().writeWith(Flux.just(buffer));

Not currently. Not quite sure how that would work right now.

My GateWay version is 2.2.5.RELEASE,I had writed a new GatewayFilterFactory to limit request,which response that rateLimiter returned was not allowed.Filter would throw the exception,but sometime Url don't match any requestMapping,the response cause to throw exception.that is weird

@spencergibb Is this the correct way to set response body?
