      Parameters:
      asyncResponse - a CompletableFuture<ServerResponse> or Publisher<ServerResponse>
      Returns:
      the asynchronous response
      Since:
      5.3

    • async

      static ServerResponse async(Object asyncResponse, Duration timeout)
      Create a (built) response with the given asynchronous response. Parameter asyncResponse can be a CompletableFuture<ServerResponse> or Publisher<ServerResponse> (or any asynchronous producer of a single ServerResponse that can be adapted via the ReactiveAdapterRegistry).

      This method can be used to set the response status code, headers, and body based on an asynchronous result. If only the body is asynchronous, ServerResponse.BodyBuilder.body(Object) can be used instead.

      Parameters:
      asyncResponse - a CompletableFuture<ServerResponse> or Publisher<ServerResponse>
      timeout - maximum time period to wait for before timing out
      Returns:
      the asynchronous response

      5.3.2

    • sse

      static ServerResponse sse(Consumer<ServerResponse.SseBuilder> consumer)
      Create a server-sent event response. The ServerResponse.SseBuilder provided to consumer can be used to build and send events.

      For example: 

       public ServerResponse handleSse(ServerRequest request) {
     return ServerResponse.sse(sse -> sse.send("Hello World!"));
 }

      or, to set both the id and event type: 

       public ServerResponse handleSse(ServerRequest request) {
     return ServerResponse.sse(sse -> sse
         .id("42)
         .event("event")
         .send("Hello World!"));
 }
      Parameters:
      consumer - consumer that will be provided with an event builder
