url中的java MockRestServiceServer转义字符

Question

在我们的项目中，我们使用了外部系统和非常不寻常的REST API。它在url中包含方括号：

api/v1/series?match[]=up

现在我们要测试我们自己的REST api，并模拟这个外部系统的响应。所以我们在单元测试中使用了MockRestServiceServer对象。

    mockServer = MockRestServiceServer.createServer(restTemplate);
    mockServer.expect(ExpectedCount.manyTimes(), requestTo(UriComponentsBuilder.fromHttpUrl(prometheusURL + "series?match[]=up")
            .build().toUri()))
            .andExpect(method(HttpMethod.GET))
            .andRespond(withSuccess(promResponseMetricUpInfo, MediaType.APPLICATION_JSON));

在我们的服务中，我们只是将这个外部API调用为

restTemplate.getForObject(prometheusURL + "series?match[]=up", ResponseObjectForSeries.class);

但结果是我们出现了以下错误：

java.lang.AssertionError: Unexpected request expected:<http://localhost:9090/api/v1/series?match[]=up> but was:<http://localhost:9090/api/v1/series?match%5B%5D=up>

我们怎样才能摆脱这些方括号呢？我尝试在测试中使用反斜杠或%5B%5D显式。但这并不管用。
