Wiremock-当返回某些媒体文件时，全局响应模板导致500

Question

我有一个测试项目，需要启用全局响应模板，因为许多模拟响应都包含动态内容。

问题是，我还需要为一些响应返回图像/视频，而这似乎与为一些图像/视频(但不是全部(创建响应模板不太好。

当它试图返回视频响应时，它似乎试图将模板应用于图像文件，并抱怨响应中存在无效字符，至少我认为这个堆栈是在告诉我(这没有显示在wiremock服务器日志中，它被封装到HTML主体中，并作为响应返回(。

这是我用来上传文件的代码：

byte[] attachmentVideo = FileUtils.loadFileBytes("classpath:payloads/video.mp4");
response = given().body(attachmentVideo).contentType("video/mp4").put(wiremockUrl() + FILES_ENDPOINT + "video.mp4");
assertThat(response.getStatusCode(), is(HttpStatus.SC_OK));

以下是返回文件的代码：

wiremock.register(WireMock.get(WireMock.urlMatching(ATTACHMENT_VIDEO_REGEX))
.willReturn(aResponse().withBodyFile("video.mp4").withHeader("Content-Type", "video/mp4")
.withStatus(200).withFixedDelay(VIDEO_RESPONSE_TIME_MS)));

一旦我关闭了全局响应模板，视频就会按预期返回。

这里唯一的选择是在启动时通过构建中的.global(false)切换到本地响应模板，并将.withTransformers("response-template")添加到需要它的存根中。
