DeviceManagementClient.GetDeviceAsync(String, RequestContext) Methode

Definition

Ruft die Geräteeigenschaften und die neueste Bereitstellung status für ein Gerät ab, das mit Device Update für IoT Hub verbunden ist.

public virtual System.Threading.Tasks.Task<Azure.Response> GetDeviceAsync (string deviceId, Azure.RequestContext context = default);
abstract member GetDeviceAsync : string * Azure.RequestContext -> System.Threading.Tasks.Task<Azure.Response>
override this.GetDeviceAsync : string * Azure.RequestContext -> System.Threading.Tasks.Task<Azure.Response>
Public Overridable Function GetDeviceAsync (deviceId As String, Optional context As RequestContext = Nothing) As Task(Of Response)

Parameter

deviceId
String

Gerätebezeichner in Azure IoT Hub.

context
RequestContext

Der Anforderungskontext, der das Standardverhalten der Clientpipeline pro Aufruf außer Kraft setzen kann.

Gibt zurück

Die vom Dienst zurückgegebene Antwort. Details zum Antworttextschema finden Sie im Abschnitt Hinweise unten.

Ausnahmen

deviceId ist NULL.

deviceId ist eine leere Zeichenfolge und wurde erwartet, dass sie nicht leer ist.

Der Dienst hat einen nicht erfolgreichen status Code zurückgegeben.

Beispiele

In diesem Beispiel wird gezeigt, wie Sie GetDeviceAsync mit den erforderlichen Parametern aufrufen und das Ergebnis analysieren.

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

Response response = await client.GetDeviceAsync("<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());
