Support UseDevelopmentStorage=true; as connection string

[hallvictoria]

• Package Name: azure-storage-blob
• Package Version: all
• Operating System: all
• Python Version: all

Describe the bug
When running Azurite / Azure Storage Explorer, the connection string commonly exposed is "UseDevelopmentStorage=true;". However, if I try to create a client-type using that as the connection string, I get an error, and I have to use a connection string like DefaultEndpointsProtocol=http;... for the client to be created correctly.

This seems to only happen for Python - .NET, Java, and Node allow client creation with "UseDevelopmentStorage=true;" as the connection string.

To Reproduce
Steps to reproduce the behavior:

1. Run Azurite with the following code:

from azure.storage.blob import BlobServiceClient

try:
    blob_service_client = BlobServiceClient.from_connection_string("UseDevelopmentStorage=true;")
    blob_client = blob_service_client.get_blob_client(
                container="mycontainer",
                blob="test.txt",
            )

except Exception as ex:
    print('Exception:')
    print(ex)

Expected behavior
The client is created without issues.

Screenshots
When running, I get this exception:

Connection string missing required connection details.

Additional context
Same issue as #10040 - this was closed without any input from the team, so just hoping we can get some information on if this will ever be supported. Thanks!

Hi @hallvictoria thanks for your issue, I'll tag the right people, and we'll take a look as soon as possible.

Hi @hallvictoria, thanks for reaching out. Given this is supported in our other languages, this seems like a good feature to add. We will take this as a feature request but we are quite busy currently so it may be a while before we get to it.

In the meantime, you can still use Azurite with the Python SDK by providing a more complete connection string like the following:

connection_string = (
    "DefaultEndpointsProtocol=http;"
    "AccountName=devstoreaccount1;"
    "AccountKey=<key>;"
    "BlobEndpoint=http://127.0.0.1:10000/devstoreaccount1;"
)

Or by using the account URL and key like this:

from azure.storage.blob import BlobServiceClient

account_name = "devstoreaccount1"
account_key = <key>
endpoint = f"http://127.0.0.1:10000/{account_name}"

blob_service_client = BlobServiceClient(
    account_url=endpoint,
    credential=account_key
)
