我正在使用带有 firebase 功能的 google iot 核心。当我请求 client.projects.locations.registries.devices.modifyCloudToDeviceConfig 我得到响应： -

如文档https://cloud.google.com/iot/docs/reference/rest/v1/projects.locations.registries.devices/modifyCloudToDeviceConfig中所述，如何从上述响应中获取 deviceacktime

它会用 deviceconfig 响应，但我无法用数据调试响应。

lastConfigAckTime 来自设备元数据，而不是对 modifyCloudToDeviceConfig 的 API 调用。

使用 API 资源管理器尝试检索您的设备。只需输入您的设备 ID，例如projects/<your-project-id>/locations/<your-cloud-region>/registries/<your-registry-id>/devices/<your-device-id>

在此处输入图像描述

可以在文档中找到各种编程语言的其他示例。
