DeviceManagementClient.GetDeviceClassSubgroup 方法

定义

获取设备类子组详细信息。 设备类子组是组中共享同一设备类的设备集。 同一设备类中的所有设备都与相同的更新兼容。

public virtual Azure.Response GetDeviceClassSubgroup (string groupId, string deviceClassId, Azure.RequestContext context = default);
abstract member GetDeviceClassSubgroup : string * string * Azure.RequestContext -> Azure.Response
override this.GetDeviceClassSubgroup : string * string * Azure.RequestContext -> Azure.Response
Public Overridable Function GetDeviceClassSubgroup (groupId As String, deviceClassId As String, Optional context As RequestContext = Nothing) As Response

参数

groupId
String

组标识符。

deviceClassId
String

设备类标识符。

context
RequestContext

请求上下文,可以基于每个调用替代客户端管道的默认行为。

返回

从服务返回的响应。 响应正文架构的详细信息,请参阅下面的“备注”部分。

例外

groupIddeviceClassId 为 null。

groupIddeviceClassId 是空字符串,预期为非空。

服务返回了非成功状态代码。

示例

此示例演示如何使用所需的参数调用 GetDeviceClassSubgroup 并分析结果。

var credential = new DefaultAzureCredential();
var endpoint = new Uri("<https://my-service.azure.com>");
var client = new DeviceManagementClient(endpoint, "<instanceId>", credential);

Response response = client.GetDeviceClassSubgroup("<groupId>", "<deviceClassId>");

JsonElement result = JsonDocument.Parse(response.ContentStream).RootElement;
Console.WriteLine(result.GetProperty("deviceClassId").ToString());
Console.WriteLine(result.GetProperty("groupId").ToString());
Console.WriteLine(result.GetProperty("createdDateTime").ToString());
Console.WriteLine(result.GetProperty("deviceCount").ToString());
Console.WriteLine(result.GetProperty("deploymentId").ToString());

注解

下面是响应有效负载的 JSON 架构。

响应正文:

DeviceClassSubgroup架构:

{
              deviceClassId: string, # Required. Device class subgroup identity. This is generated from the model Id and the compat properties reported by the device update agent in the Device Update PnP interface in IoT Hub. It is a hex-encoded SHA1 hash.
              groupId: string, # Required. Group identity.
              createdDateTime: string, # Required. Date and time when the device class subgroup was created.
              deviceCount: number, # Optional. The number of devices in the device class subgroup.
              deploymentId: string, # Optional. The active deployment Id for the device class subgroup.
            }
