Renew SasKey for BlobContainerClient

Library name

Azure.Storage.Blobs

Please describe the feature.

Hi,

We receive 1 hour write sas key and were wondering how to renew it once the BlobContainerClient is created.

For example:

var containerclient = new BlobContainerClient(new Uri("https://storageaccount.blob.core.windows.net/containername?sig=something")
// Start upload
// 1 hour later, the sas key is expired and the upload fails.

How can we deal with this case? Is there a way to give a callback for new signature? Should I implement a custom TokenCredential or implement a custom HttpClientTransport and modify the Uri on the fly with a renewed signature? Or others method?

Please advise.

Hi, you can use the AzureSasCredential instead when instantiating your client.

So it would something like

AzureSasCredential credential = new AzureSasCredential(sas);
BlobContainerClient containerClient = new BlobContainerClient(uri, credential, options);

Then when your SAS expires you could do something like

// Wait 1 hour
credential.Update(newSas);
