  • 方法详细资料

    • filter

      R filter(ServerRequest request, HandlerFunction<T> next) throws Exception
      Apply this filter to the given handler function. The given handler function represents the next entity in the chain, and can be invoked in order to proceed to this entity, or not invoked to block the chain.
      参数:
      request - the request
      next - the next handler or filter function in the chain
      返回:
      the filtered response
      抛出:
      Exception

    • andThen

      default HandlerFilterFunction<T,R> andThen(HandlerFilterFunction<T,T> after)
      Return a composed filter function that first applies this filter, and then applies the after filter.
      参数:
      after - the filter to apply after this filter is applied
      返回:
      a composed filter that first applies this function and then applies the after function

    • apply

      default HandlerFunction<R> apply(HandlerFunction<T> handler)
      Apply this filter to the given handler function, resulting in a filtered handler function.
      参数:
      handler - the handler function to filter
      返回:
      the filtered handler function

    • ofRequestProcessor

      static <T extends ServerResponse> HandlerFilterFunction<T,T> ofRequestProcessor(Function<ServerRequest,ServerRequest> requestProcessor)
      Adapt the given request processor function to a filter function that only operates on the ServerRequest.
      参数:
      requestProcessor - the request processor
      返回:
      the filter adaptation of the request processor

    • ofResponseProcessor

      static <T extends ServerResponse, R extends ServerResponse> HandlerFilterFunction<T,R> ofResponseProcessor(BiFunction<ServerRequest,T,R> responseProcessor)
      Adapt the given response processor function to a filter function that only operates on the ServerResponse.
      参数:
      responseProcessor - the response processor
      返回:
      the filter adaptation of the request processor

    • ofErrorHandler

      static <T extends ServerResponse> HandlerFilterFunction<T,T> ofErrorHandler(Predicate<Throwable> predicate, BiFunction<Throwable,ServerRequest,T> errorHandler)
      Adapt the given predicate and response provider function to a filter function that returns a ServerResponse on a given exception.
      参数:
      predicate - the predicate to match an exception
      errorHandler - the response provider
      返回:
      the filter adaption of the error handler
