How to generate download URL for azure container in Python

I have a container named test in azure storage. I want to generate URL for this. File directory inside it looks like below:

test
    -> annotate # This is a dir
        -> file1.txt
        -> file2.txt
    -> images # This is a dir
        -> file1.jpg
        -> file2.jpg

I want to generate URL so that when it is accessed I can download the complete container test including all the files and directories inside it. Now I have done this before but in that approach I was only downloading the blob using below code:

account_name = "deeusblobstorage"
container_name = "rperodct"
blob_name = "face_1_7285.jpg"
account_key = "hMlIRXCjAomfDRfied8Y5FPwTVnWEkEDuVsw//CQtkiOdcFD/y5wUcxH9Ou7Ni+DtDQFwe23YbZ3Qia9gw=="
url = f"https://{account_name}.blob.core.windows.net/{container_name}/{blob_name}"
sas_token = generate_blob_sas(
    account_name=account_name,
    account_key=account_key,
    container_name=container_name,
    blob_name=blob_name,
    permission=AccountSasPermissions(read=True),
    expiry=datetime.datetime.utcnow() + timedelta(hours=1)
)

url_with_sas = f"{url}?{sas_token}"
print(url_with_sas)

In the above code I was specifically mentioning the blob inside the container to download, which then generates url. But how can we generate url for a container so that all the files and directories inside it can also be downloaded. Thanks

But how can we generate url for a container so that all the files and directories inside it can also be downloaded.

Simply put, you cannot directly download all blobs in a container just by using a container URL. What you would need to do is first list the blobs inside the container and then download individual blobs.

In order to list the blobs in a container and then download each blob, you would need to generate a SAS token on the container using generate_container_sas method. You would need both read and list permissions in your SAS token.

Once you have the SAS token, you would first list the blobs and then create SAS URL for each blob using the blob URL and SAS token you obtained for the container.
