获取连接到设备更新的设备的设备IoT 中心的设备属性和最新部署状态。

public virtual Azure.Response GetDevice (string deviceId, Azure.RequestContext context = default);

abstract member GetDevice : string * Azure.RequestContext -> Azure.Response
override this.GetDevice : string * Azure.RequestContext -> Azure.Response

Public Overridable Function GetDevice (deviceId As String, Optional context As RequestContext = Nothing) As Response

参数

deviceId: String

Azure IoT 中心中的设备标识符。

context: RequestContext

请求上下文，它可以基于每个调用替代客户端管道的默认行为。

Response

从服务返回的响应。响应正文架构的详细信息位于下面的“备注”部分。

例外

ArgumentNullException

deviceId 为 null。

ArgumentException

deviceId 是一个空字符串，预期为非空。

RequestFailedException

服务返回了不成功状态代码。

示例

此示例演示如何使用所需参数调用 GetDevice 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.GetDevice("<deviceId>");

JsonElement result = JsonDocument.Parse(response.ContentStream).RootElement;
Console.WriteLine(result.GetProperty("deviceId").ToString());
Console.WriteLine(result.GetProperty("moduleId").ToString());
Console.WriteLine(result.GetProperty("deviceClassId").ToString());
Console.WriteLine(result.GetProperty("groupId").ToString());
Console.WriteLine(result.GetProperty("lastAttemptedUpdate").GetProperty("updateId").GetProperty("provider").ToString());
Console.WriteLine(result.GetProperty("lastAttemptedUpdate").GetProperty("updateId").GetProperty("name").ToString());
Console.WriteLine(result.GetProperty("lastAttemptedUpdate").GetProperty("updateId").GetProperty("version").ToString());
Console.WriteLine(result.GetProperty("lastAttemptedUpdate").GetProperty("description").ToString());
Console.WriteLine(result.GetProperty("lastAttemptedUpdate").GetProperty("friendlyName").ToString());
Console.WriteLine(result.GetProperty("deploymentStatus").ToString());
Console.WriteLine(result.GetProperty("installedUpdate").GetProperty("updateId").GetProperty("provider").ToString());
Console.WriteLine(result.GetProperty("installedUpdate").GetProperty("updateId").GetProperty("name").ToString());
Console.WriteLine(result.GetProperty("installedUpdate").GetProperty("updateId").GetProperty("version").ToString());
Console.WriteLine(result.GetProperty("installedUpdate").GetProperty("description").ToString());
Console.WriteLine(result.GetProperty("installedUpdate").GetProperty("friendlyName").ToString());
Console.WriteLine(result.GetProperty("onLatestUpdate").ToString());
Console.WriteLine(result.GetProperty("lastDeploymentId").ToString());
Console.WriteLine(result.GetProperty("lastInstallResult").GetProperty("resultCode").ToString());
Console.WriteLine(result.GetProperty("lastInstallResult").GetProperty("extendedResultCode").ToString());
Console.WriteLine(result.GetProperty("lastInstallResult").GetProperty("resultDetails").ToString());
Console.WriteLine(result.GetProperty("lastInstallResult").GetProperty("stepResults")[0].GetProperty("update").GetProperty("updateId").GetProperty("provider").ToString());
Console.WriteLine(result.GetProperty("lastInstallResult").GetProperty("stepResults")[0].GetProperty("update").GetProperty("updateId").GetProperty("name").ToString());
Console.WriteLine(result.GetProperty("lastInstallResult").GetProperty("stepResults")[0].GetProperty("update").GetProperty("updateId").GetProperty("version").ToString());
Console.WriteLine(result.GetProperty("lastInstallResult").GetProperty("stepResults")[0].GetProperty("update").GetProperty("description").ToString());
Console.WriteLine(result.GetProperty("lastInstallResult").GetProperty("stepResults")[0].GetProperty("update").GetProperty("friendlyName").ToString());
Console.WriteLine(result.GetProperty("lastInstallResult").GetProperty("stepResults")[0].GetProperty("description").ToString());
