Generate SAS tokens with get_service_sas or get_account_sas

[dempseynoel]

I'm trying to generate SAS tokens using the two functions mentioned above. Using example code in the docs (below) a SAS token is generated, however when I append this to the end of the blob I want to access I get an error stating the signature did not match.

I generate the SAS as follows:

endp <- storage_endpoint(Sys.getenv("LONDON_BUS_STORAGE_ENDPOINT"), key=Sys.getenv("LONDON_BUS_STORAGE_KEY"))

sas <- get_service_sas(endp, resource = Sys.getenv("LONDON_BUS_ANNOTATE_CONTAINER_NAME"), permissions="r")

blob_file_url_with_sas <- paste0(Sys.getenv("LONDON_BUS_STORAGE_ENDPOINT"), "/", Sys.getenv("LONDON_BUS_ANNOTATE_CONTAINER_NAME"), "/", Sys.getenv("LONDON_BUS_ANNOTATE_FILE"), sas)

Where the environmental variables relate to the storage account, storage account key, container name, and the name of the blob.

The error is:

<Error> <Code>AuthenticationFailed</Code> <Message>Server failed to authenticate the request. Make sure the value of Authorization header is formed correctly including the signature. RequestId:2b7236bd-301e-004c-2d6b-757ef4000000 Time:2024-03-13T17:22:19.7678924Z</Message> <AuthenticationErrorDetail>Signature did not match. String to sign used was r 2024-03-13T17:07:02Z 2024-03-14T01:07:02Z /blob/{{MY_STORAGE_ACCOUNT}}/{{MY_CONTAINER}} 2021-06-08 c </AuthenticationErrorDetail> </Error>

When I generate a SAS token in the GUI in my Azure account everything works. I'm only trying to generate with AzureStor so that I can generate frequently for extra security.

Any help on this is much appreciated. I've tried numerous variations of the SAS.
