GetHeaderAsync(String, RequestContext)

- Entity.cs
[Protocol Method] Get entity header given its GUID.
- This protocol method allows explicit creation of the request and processing of the response for advanced scenarios.
- Please try the simpler GetHeaderAsync(String, CancellationToken) convenience overload with strongly typed models first.
public virtual System.Threading.Tasks.Task<Azure.Response> GetHeaderAsync (string guid, Azure.RequestContext context);abstract member GetHeaderAsync : string * Azure.RequestContext -> System.Threading.Tasks.Task<Azure.Response>
override this.GetHeaderAsync : string * Azure.RequestContext -> System.Threading.Tasks.Task<Azure.Response>Public Overridable Function GetHeaderAsync (guid As String, context As RequestContext) As Task(Of Response)Parameters
- guid
- String
The globally unique identifier of the entity.
- context
- RequestContext
The request context, which can override default behaviors of the client pipeline on a per-call basis.
Returns
The response returned from the service.
Exceptions
guid is null.
guid is an empty string, and was expected to be non-empty.
Service returned a non-success status code.
Examples
This sample shows how to call GetHeaderAsync and parse the result.
Uri endpoint = new Uri("<https://my-service.azure.com>");
TokenCredential credential = new DefaultAzureCredential();
Entity client = new DataMapClient(endpoint, credential).GetEntityClient();
Response response = await client.GetHeaderAsync("<guid>", null);
JsonElement result = JsonDocument.Parse(response.ContentStream).RootElement;
Console.WriteLine(result.ToString());
This sample shows how to call GetHeaderAsync with all parameters and parse the result.
