我设法通过这样做找到了解决方案：我给存根赋予了UUID

stubFor(post(urlPathEqualTo(getUploadEndpoint())).willReturn(aResponse().withStatus(HttpStatus.OK.value()))).withId(java.util.UUID.fromString(UUID)));

我收集了这个端点上发生的所有服务器事件

List<ServeEvent> allServeEvents getAllServeEvents(ServeEventQuery.forStubMapping(java.util.UUID.fromString(UUID)));
// this list should contain one stub only
assertThat(allServeEvents).hasSize(1);
ServeEvent request = allServeEvents.get(0);
String body = request .getRequest().getBodyAsString();

然后我使用XMLUnit来Assert这个主体。看起来可以完成这项工作，但如果有其他解决方案，我也会考虑。

或者，您可以使用API查找与 predicate 匹配的请求：

import static com.github.tomakehurst.wiremock.client.WireMock.*;

List<LoggedRequest> requests = findAll(
    postRequestedFor(urlEqualTo(getUploadEndpoint()))
        .withRequestBody(matchingXPath("your xpath here"))
);

然后，您可以Assert关于匹配请求的任何内容。

您可以使用该API执行verify that a request was made with the expected body。

import static com.github.tomakehurst.wiremock.client.WireMock.*

verify(
    postRequestedFor(urlEqualTo(getUploadEndpoint()))
        .withRequestBody(matchingXPath("your xpath here"))
);

有关XPath匹配的示例，请参见WireMock /请求匹配/ XPath。
