Azur storage upload with R

Azur storage upload with R

BESSY-ROLAND Yannick 6

Hello,

I'm using R to upload files on a Azur Storage accout, with libraries AzureStor and AzureRMR.

The main steps are to use firstly this command : cont <- storage_container(endp, container_name), and then to use the function storage_upload.
I'm using two computers, using the exact same lines of code works for the first one, but no more for the second one, I indeed obtain this error :

Error in process_storage_response(response, match.arg(http_status_handler), :
Forbidden (HTTP 403). Failed to complete Storage Services operation. Message:
AuthorizationFailure
This request is not authorized to perform this operation.

Some days ago I could use both computers with this exact same code to upload files on Azure. Now one of them give me this error.
Also my public IP is allowed in the Azur account parameters.

Any thoughts?

Thanks

@BESSY-ROLAND Yannick Can you please share code?
Are you using SAS? If so, can you please regenerate the SAS token and try again.
Often times 403 is seen when authorizing with a shared key because "All authorized requests must include the Coordinated Universal Time (UTC) timestamp for the request." Information about this can be found in Authorize with Shared Key

You can specify the timestamp either in the x-ms-date header, or in the standard HTTP/HTTPS Date header. The storage services ensure that a request is no older than 15 minutes by the time it reaches the service. This guards against certain security attacks, including replay attacks. When this check fails, the server returns response code 403 (Forbidden). Check your Server data-time in this scenario

endp <- storage_endpoint("https://acctname.blob.core.windows.net", key="access_key")
cont <- storage_container(endp, "mycontainer")
storage_download(cont, "myblob.csv", "local_filename.csv")

Thanks for your answer !

The code looks like this :

I've checked the time in Rstudio using Sys.time(), I have the same correct time as my computer.

Concerning this remark : "You can specify the timestamp either in the x-ms-date header, or in the standard HTTP/HTTPS Date header. The storage services ensure that a request is no older than 15 minutes by the time it reaches the service. This guards against certain security attacks, including replay attacks.

Could you precise were I am supposed to make changes? In R or in Azur storage?

Thanks

@BESSY-ROLAND Yannick Apologies for the delay response! Can you re-generate the SAS key in Azure Storage and try again and let me know the status.

Additional information: You can also refer to this blog, which gives some idea on your scenario

If the issue still persist, I would love work closer on this issue
