带有正文的 Reactive WebClient GET 请求在 MockWebServer 测试中失败

Question

在我的连接器类中，我使用 Spring 将带有主体的 API GET 调用下游到另一个服务，如下所示。

WebClient

我要用下面的测试用例来测试它：

public Mono<SampleResponse> getSampleResponse(final int id, final SampleRequest sampleRequest) {
    return webclient
        .method(HttpMethod.GET)
        .uri("get/sample/{id}", id)
        .body(Mono.just(sampleRequest), SampleRequest .class)
        .accept(MediaType.APPLICATION_JSON)
        .retrieve()
        .onStatus(HttpStatus.NOT_FOUND::equals, r -> Mono.empty())
        .onStatus(HttpStatus::isError, r -> Mono.empty())
        .bodyToMono(SampleResponse.class)
        .doOnError(throwable -> log.error(EXTERNAL_SERVICE_ERROR, throwable.getMessage()));
}

我的考试不及格。

private MockWebServer server;
private SampleResponseConnector connector;

@BeforeEach
void setup() {
    server = new MockWebServer();
    ReactiveWebClientConnectorFactory factory = new ReactiveWebClientConnectorFactory();
    connector = new SampleResponseConnector (factory.createWebClient(
        server.url("/").toString(), "", null, null, null));
}

@Test
public void getSampleResponse_callsDownstreamSuccessfully() {
    Random random = new Random();
    int id = random.nextInt(10);
    mockResponse("{\"available\":[\"CUSTOMER_ADDRESS\",\"CUSTOMER_QUERY\"]}");
    SampleRequest request = SampleRequest .builder().build();
    StepVerifier.create(connector.getSampleResponse(id, request))
                .expectNextMatches(response -> response.getAvailable().equals(List.of("CUSTOMER_ADDRESS", "CUSTOMER_QUERY")))
                .verifyComplete();
}

private void mockResponse(String json) {
    MockResponse response = new MockResponse();
    response.setHeader("Content-Type", "application/json");
    response.setBody(json);
    server.enqueue(response);
}

任何指针将不胜感激。
