accept

Registers a custom accepted content types contributor. A contributor function takes io.ktor.server.application.ApplicationCall and a list of content types accepted according to the HttpHeaders.Accept header or provided by the previous contributor if exists. The result of this contributor should be a list of accepted content types with a quality. A contributor could either keep or replace input list of accepted content types depending on a use case. For example, a contributor taking the format=json request parameter could replace the original content types list with the specified one from the uri argument. Note that the returned list of accepted types will be sorted according to the quality using sortedByQuality, so a custom contributor may keep it unsorted and should not rely on input list order.
