Examples with Request feign.Request used on opensource projects

Example 1 with Request

use of feign.Request in project spring-cloud-sleuth by spring-cloud.

the class FeignRetriesTests method testRetriedWhenExceededNumberOfRetries.

@Test
public void testRetriedWhenExceededNumberOfRetries() throws Exception {
    Client client = (request, options) -> {
        throw new IOException();
    };
    String url = "http://localhost:" + server.getPort();
    TestInterface api = Feign.builder().client(new TracingFeignClient(this.httpTracing, client)).target(TestInterface.class, url);
    try {
        api.decodedPost();
        failBecauseExceptionWasNotThrown(FeignException.class);
    } catch (FeignException e) {
    }
}

Example 2 with Request

use of feign.Request in project spring-cloud-sleuth by spring-cloud.

the class FeignRetriesTests method testRetriedWhenRequestEventuallyIsSent.

@Test
public void testRetriedWhenRequestEventuallyIsSent() throws Exception {
    String url = "http://localhost:" + server.getPort();
    final AtomicInteger atomicInteger = new AtomicInteger();
    // Client to simulate a retry scenario
    final Client client = (request, options) -> {
        // we simulate an exception only for the first request
        if (atomicInteger.get() == 1) {
            throw new IOException();
        } else {
            // with the second retry (first retry) we send back good result
            return Response.builder().status(200).reason("OK").headers(new HashMap<>()).body("OK", Charset.defaultCharset()).build();
        }
    };
    TestInterface api = Feign.builder().client(new TracingFeignClient(this.httpTracing, new Client() {

        @Override
        public Response execute(Request request, Request.Options options) throws IOException {
            atomicInteger.incrementAndGet();
            return client.execute(request, options);
        }
    })).target(TestInterface.class, url);
    then(api.decodedPost()).isEqualTo("OK");
    // request interception should take place only twice (1st request & 2nd retry)
    then(atomicInteger.get()).isEqualTo(2);
    then(this.reporter.getSpans().get(0).tags()).containsEntry("error", "IOException");
    then(this.reporter.getSpans().get(1).kind().ordinal()).isEqualTo(Span.Kind.CLIENT.ordinal());
}

Example 3 with Request

use of feign.Request in project feign by OpenFeign.

the class ReactiveFeignIntegrationTest method testErrorDecoder.

@SuppressWarnings({ "ThrowableNotThrown" })
@Test
public void testErrorDecoder() {
    this.webServer.enqueue(new MockResponse().setBody("Bad Request").setResponseCode(400));
    ErrorDecoder errorDecoder = mock(ErrorDecoder.class);
    given(errorDecoder.decode(anyString(), any(Response.class))).willReturn(new IllegalStateException("bad request"));
    TestReactiveXService service = RxJavaFeign.builder().errorDecoder(errorDecoder).target(TestReactiveXService.class, this.getServerUrl());
    StepVerifier.create(service.search(new SearchQuery())).expectErrorSatisfies(ex -> assertThat(ex).isInstanceOf(IllegalStateException.class).hasMessage("bad request")).verify();
    verify(errorDecoder, times(1)).decode(anyString(), any(Response.class));
}

Example 4 with Request

use of feign.Request in project feign by OpenFeign.

the class ReactiveFeignIntegrationTest method testClient.

@Test
public void testClient() throws Exception {
    Client client = mock(Client.class);
    given(client.execute(any(Request.class), any(Options.class))).willAnswer((Answer<Response>) invocation -> Response.builder().status(200).headers(Collections.emptyMap()).body("1.0", Charset.defaultCharset()).request((Request) invocation.getArguments()[0]).build());
    TestReactorService service = ReactorFeign.builder().client(client).target(TestReactorService.class, this.getServerUrl());
    StepVerifier.create(service.version()).expectNext("1.0").expectComplete().verify();
    verify(client, times(1)).execute(any(Request.class), any(Options.class));
}

Example 5 with Request

use of feign.Request in project feign by OpenFeign.

the class RequestKeyTest method create.

@SuppressWarnings("deprecation")
@Test
public void create() throws Exception {
    Map<String, Collection<String>> map = new HashMap<String, Collection<String>>();
    map.put("my-header", Arrays.asList("val"));
    Request request = Request.create(Request.HttpMethod.GET, "a", map, "content".getBytes(StandardCharsets.UTF_8), StandardCharsets.UTF_16);
    requestKey = RequestKey.create(request);
    assertThat(requestKey.getMethod(), equalTo(HttpMethod.GET));
    assertThat(requestKey.getUrl(), equalTo("a"));
    assertThat(requestKey.getHeaders().size(), is(1));
    assertThat(requestKey.getHeaders().fetch("my-header"), equalTo((Collection<String>) Arrays.asList("val")));
    assertThat(requestKey.getCharset(), equalTo(StandardCharsets.UTF_16));
