使用过滤条件列出数据

使用 API 列出数据时，某些列表方法请求会提供 filter 字段。您可以使用这些过滤条件仅返回您感兴趣的结果。这种过滤功能在许多 Google Cloud API 中很常见。

以下示例展示了如何在列出测试用例结果时过滤响应。

    // Note: close() needs to be called on the TestCasesClient object to clean up resources
    // such as threads. In the example below, try-with-resources is used,
    // which automatically calls close().
    try (TestCasesClient client = TestCasesClient.create(testCasesSettings)) {
      for (TestCaseResult element : client.listTestCaseResults(req.build()).iterateAll()) {
        System.out.println(element);
