Question
Hey folks, I ran into a bit of a roadblock while building my app with Dapr and wanted to share what’s going on — maybe you’ve seen something similar or have some guidance?
Trouble Generating SAS Token for Blob Storage
What’s the deal?:
I am using Azure Blob Storage, which—as you probably know—needs a SAS token to access files securely. The bindings.azure.blobstorage binding in Dapr currently supports basic operations like get, create, delete, and list, but doesn’t seem to directly support generating SAS tokens.
What I have tried:
I gave it a shot by tweaking the metadata in our requests, hoping I could trigger SAS token generation that way. Here’s what I did:
- 1 with
get– here I receive the file data:
{
"operation": "get",
"metadata": {
"sasToken": "true",
"blobName": "<filename>"
}
}- 2 with
create– here I receive the presigned URL:
{
"operation": "create",
"metadata": {
"sasToken": "true",
"blobName": "<filename>"
}
}Where I am at::
It looks like Dapr doesn’t currently support SAS token generation directly, at least not in a straightforward way. If there’s a trick I am missing, I’d love to hear it. Otherwise, maybe this could be something to consider as a future enhancement?
Let me know what you think — any tips or workarounds are more than welcome!
