Azure storage for url access control/expiration does not work with Django 5.1+

[jeffpfoster]

Our environment is currently working fine with django 5.0 and returns urls for azure storage with the correct parameters on the url

If we upgrade to 5.1 or 5.2 version of django the url for storage files only return the file with no parameters.

Hi,
have you set the expiration_secs setting? Otherwise no signed urls will be generated. Not sure if something changed with the Django version, we are using Django 5.1.6 and it works just fine.

We are using the env var 'AZURE_URL_EXPIRATION_SECS = 300'. Do you mine posting any deps related you're using?

We've got in our environment

...
azure-identity
django-storages[azure]
django_extensions
...

[jgoedeke]

...
azure-identity==1.21.0
django-storages[s3,azure]==1.14.5
azure-core==1.32.0
azure-identity==1.21.0
azure-storage-blob==12.25.0
...

those should be the relevant once, and here is the configuration:

STORAGES = {
    'default': {
            'BACKEND': 'storages.backends.azure_storage.AzureStorage',
            'OPTIONS': {
                'account_name': os.getenv('AZURE_ACCOUNT_NAME'),
                'azure_container': 'container',
                'token_credential': DefaultAzureCredential(),
                'custom_domain': f'{DOMAIN}/assets',  # works also without
                'expiration_secs': 60 * 60 * 24,
                'overwrite_files': True,
                location': 'some/location/',
            },
        }
    ),

There may be problems with the lifetime value (e.g. expiration_seconds too short), see: https://stackoverflow.com/a/66311414
