Examples with MapBackedKeySupplier io.reactivex.netty.contexts.MapBackedKeySupplier used on opensource projects

Example 1 with MapBackedKeySupplier

use of io.reactivex.netty.contexts.MapBackedKeySupplier in project ribbon by Netflix.

the class NettyClientTest method testContext.

@Test
public void testContext() throws Exception {
    HttpClientRequest<ByteBuf> request = HttpClientRequest.createGet(SERVICE_URI + "testAsync/context");
    LoadBalancingHttpClient<ByteBuf, ByteBuf> observableClient = RibbonTransport.newHttpClient();
    String requestId = "xyz";
    ContextsContainerImpl contextsContainer = new ContextsContainerImpl(new MapBackedKeySupplier());
    contextsContainer.addContext("Context1", "value1");
    RxContexts.DEFAULT_CORRELATOR.onNewServerRequest(requestId, contextsContainer);
    Observable<HttpClientResponse<ByteBuf>> response = observableClient.submit(new Server(host, port), request);
    final AtomicReference<ContextsContainer> responseContext = new AtomicReference<ContextsContainer>();
    String requestIdSent = response.flatMap(new Func1<HttpClientResponse<ByteBuf>, Observable<ByteBuf>>() {

        @Override
        public Observable<ByteBuf> call(HttpClientResponse<ByteBuf> t1) {
            return t1.getContent();
        }
    }).map(new Func1<ByteBuf, String>() {

        @Override
        public String call(ByteBuf t1) {
            String requestId = RxContexts.DEFAULT_CORRELATOR.getRequestIdForClientRequest();
            responseContext.set(RxContexts.DEFAULT_CORRELATOR.getContextForClientRequest(requestId));
            return t1.toString(Charset.defaultCharset());
        }
    }).toBlocking().single();
    assertEquals(requestId, requestIdSent);
    assertEquals("value1", responseContext.get().getContext("Context1"));
