Class ReactiveRequest

java.lang.Object

org.eclipse.jetty.reactive.client.ReactiveRequest

public class ReactiveRequest
extends Object

A reactive wrapper over Jetty's HttpClient Request.

A ReactiveRequest can be obtained via a builder:

 // Built with HttpClient and a string URI.
 ReactiveRequest request = ReactiveRequest.newBuilder(httpClient, uri()).build();

 // Built by wrapping a Request.
 Request req = httpClient.newRequest(...);
 ...
 ReactiveRequest request = ReactiveRequest.newBuilder(req).build();
 

Once created, a ReactiveRequest can be sent to obtain a Publisher for a ReactiveResponse passing a function that handles the response content:

 Publisher<T> response = request.response((response, content) -> { ... });

Method Detail

newBuilder

public static ReactiveRequest.Builder newBuilder(org.eclipse.jetty.client.HttpClient httpClient,
                                                 String uri)

Parameters:

httpClient - the HttpClient instance

uri - the target URI for the request - must be properly encoded already

Returns:

a builder for a GET request for the given URI

newBuilder

public static ReactiveRequest.Builder newBuilder(org.eclipse.jetty.client.api.Request request)

Parameters:

request - the request instance

Returns:

a builder for the given Request

getReactiveResponse

public ReactiveResponse getReactiveResponse()

Returns:

the ReactiveResponse correspondent to this request, or null if the response is not available yet

getRequest

public org.eclipse.jetty.client.api.Request getRequest()

Returns:

the wrapped Jetty request

response

public org.reactivestreams.Publisher<ReactiveResponse> response()

Creates a Publisher that sends the request when a Subscriber requests the response via Subscription.request(long), discarding the response content.

Returns:

a Publisher for the response

response

public <T> org.reactivestreams.Publisher<T> response(BiFunction<ReactiveResponse,org.reactivestreams.Publisher<ContentChunk>,org.reactivestreams.Publisher<T>> contentFn)

Creates a Publisher that sends the request when a Subscriber requests the response via Subscription.request(long), processing the response content with the given function.

Applications must subscribe (possibly asynchronously) to the response content Publisher, even if it is known that the response has no content, to receive the response success/failure events.

Type Parameters:

T - the element type of the processed response content

Parameters:

contentFn - the function that processes the response content

Returns:

a Publisher for the processed content

requestEvents

public org.reactivestreams.Publisher<ReactiveRequest.Event> requestEvents()

Returns:

a Publisher for request events

responseEvents

public org.reactivestreams.Publisher<ReactiveResponse.Event> responseEvents()

toString

public String toString()

Overrides:

toString in class Object
