DeviceManagementClient.GetOperationStatusAsync 方法

定义

命名空间:

Azure.IoT.DeviceUpdate

程序集:

Azure.IoT.DeviceUpdate.dll

包:

Azure.IoT.DeviceUpdate v1.0.0

Source:

DeviceManagementClient.cs

检索操作状态。

public virtual System.Threading.Tasks.Task<Azure.Response> GetOperationStatusAsync (string operationId, Azure.ETag? ifNoneMatch = default, Azure.RequestContext context = default);

abstract member GetOperationStatusAsync : string * Nullable<Azure.ETag> * Azure.RequestContext -> System.Threading.Tasks.Task<Azure.Response>
override this.GetOperationStatusAsync : string * Nullable<Azure.ETag> * Azure.RequestContext -> System.Threading.Tasks.Task<Azure.Response>

Public Overridable Function GetOperationStatusAsync (operationId As String, Optional ifNoneMatch As Nullable(Of ETag) = Nothing, Optional context As RequestContext = Nothing) As Task(Of Response)

参数

operationId

String

操作标识符。

ifNoneMatch

Nullable<ETag>

定义 If-None-Match 条件。 仅当服务器上的 ETag 与此值不匹配时，才会执行该操作。

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。

返回

Task<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

operationId 为 null。

ArgumentException

operationId 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 GetOperationStatusAsync 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 = await client.GetOperationStatusAsync("<operationId>");

JsonElement result = JsonDocument.Parse(response.ContentStream).RootElement;
Console.WriteLine(result.GetProperty("operationId").ToString());
Console.WriteLine(result.GetProperty("status").ToString());
Console.WriteLine(result.GetProperty("lastActionDateTime").ToString());
Console.WriteLine(result.GetProperty("createdDateTime").ToString());

此示例演示如何使用所有参数调用 GetOperationStatusAsync，以及如何分析结果。

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

Response response = await client.GetOperationStatusAsync("<operationId>", null);

JsonElement result = JsonDocument.Parse(response.ContentStream).RootElement;
Console.WriteLine(result.GetProperty("operationId").ToString());
Console.WriteLine(result.GetProperty("status").ToString());
Console.WriteLine(result.GetProperty("error").GetProperty("code").ToString());
Console.WriteLine(result.GetProperty("error").GetProperty("message").ToString());
Console.WriteLine(result.GetProperty("error").GetProperty("target").ToString());
Console.WriteLine(result.GetProperty("error").GetProperty("innererror").GetProperty("code").ToString());
Console.WriteLine(result.GetProperty("error").GetProperty("innererror").GetProperty("message").ToString());
Console.WriteLine(result.GetProperty("error").GetProperty("innererror").GetProperty("errorDetail").ToString());
Console.WriteLine(result.GetProperty("error").GetProperty("occurredDateTime").ToString());
Console.WriteLine(result.GetProperty("traceId").ToString());
Console.WriteLine(result.GetProperty("lastActionDateTime").ToString());
Console.WriteLine(result.GetProperty("createdDateTime").ToString());
Console.WriteLine(result.GetProperty("etag").ToString());
