Interface ExchangeFunction

Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface public interface ExchangeFunction
Represents a function that exchanges a request for a (delayed) ClientResponse. Can be used as an alternative to WebClient.

For example:

 ExchangeFunction exchangeFunction =
         ExchangeFunctions.create(new ReactorClientHttpConnector());

 URI url = URI.create("");
 ClientRequest request = ClientRequest.create(HttpMethod.GET, url).build();

 Mono<String> bodyMono = exchangeFunction
     .flatMap(response -> response.bodyToMono(String.class));

    • exchange

      reactor.core.publisher.Mono<ClientResponse> exchange(ClientRequest request)
      Exchange the given request for a ClientResponse promise.

      Note: When calling this method from an ExchangeFilterFunction that handles the response in some way, extra care must be taken to always consume its content or otherwise propagate it downstream for further handling, for example by the WebClient. Please see the reference documentation for more details on this.

      request - the request to exchange
      the delayed response
    • filter

      default ExchangeFunction filter(ExchangeFilterFunction filter)
      Filter the exchange function with the given ExchangeFilterFunction, resulting in a filtered ExchangeFunction.
      filter - the filter to apply to this exchange
      the filtered exchange
