I’m using the spring webclient to make my api calls, and one of the calls has a optional trailer response if anything went wrong. The response is chunked encoded.

A simple example:

< HTTP/1.1 200 OK
< Transfer-Encoding: chunked
< Content-Type: text/binary
< Connection: Keep-Alive
< Keep-Alive: timeout-20
< Date: Fri, 03 May 2024 14:26:43 GMT
< Cache-Control: max-age=1
< accept-ranges: bytes
<
0
x-result: 1
x-error: Failed to determine asset size

If i make the request the response body is empty for the above, but i can’t access the trailer headers.

List<byte[]> response = webClient.get().uri( "https://apiwithtailerresponse.com" )
                .retrieve().bodyToFlux( byte[].class )
                .collectList()
                .block();

Any way to retrieve the trailer headers values?
