azure.storage.blob.BlobClient.from_blob_url() parses incorrect blob name and container name

[chrisyeh96]

• Package Name: azure-storage-blob
• Package Version: 12.3.2
• Operating System: Windows 10 Version 10.0.19041 Build 19041, running WSL 1
• Python Version: 3.8.3

Describe the bug
azure.storage.blob.BlobClient.get_blob_properties() returns incorrect "name" and "container" properties

To Reproduce
Steps to reproduce the behavior:

Code

from azure.storage.blob import BlobClient

PUBLIC_BLOB_URI = 'https://lilablobssc.blob.core.windows.net/nacti-unzipped/part0/sub000/2010_Unit150_Ivan097_img0003.jpg'

blob_client = BlobClient.from_blob_url(PUBLIC_BLOB_URI)
properties = blob_client.get_blob_properties()
print(properties['name'])
print(properties['container'])

Running Code in Python REPL:

>>> from azure.storage.blob import BlobClient
>>>
>>> PUBLIC_BLOB_URI = 'https://lilablobssc.blob.core.windows.net/nacti-unzipped/part0/sub000/2010_Unit150_Ivan097_img0003.jpg'
>>>
>>> blob_client = BlobClient.from_blob_url(PUBLIC_BLOB_URI)
>>> properties = blob_client.get_blob_properties()
>>> print(properties['name'])
2010_Unit150_Ivan097_img0003.jpg
>>> print(properties['container'])
sub000

Expected behavior
A clear and concise description of what you expected to happen.

The blob name should be "part0/sub000/2010_Unit150_Ivan097_img0003.jpg" instead of "2010_Unit150_Ivan097_img0003.jpg" and the container should be "nacti-unzipped" instead of "sub000".

Update: the issue is actually in azure.storage.blob.BlobClient.from_blob_url(), so I updated the issue title to match.

from azure.storage.blob import BlobClient

PUBLIC_BLOB_URI = 'https://lilablobssc.blob.core.windows.net/nacti-unzipped/part0/sub000/2010_Unit150_Ivan097_img0003.jpg'

blob_client = BlobClient.from_blob_url(PUBLIC_BLOB_URI)
print(blob_client.blob_name)
print(blob_client.container_name)

Running Code in Python REPL:

>>> from azure.storage.blob import BlobClient
>>>
>>> PUBLIC_BLOB_URI = 'https://lilablobssc.blob.core.windows.net/nacti-unzipped/part0/sub000/2010_Unit150_Ivan097_img0003.jpg'
>>>
>>> blob_client = BlobClient.from_blob_url(PUBLIC_BLOB_URI)
>>> print(blob_client.blob_name)
'2010_Unit150_Ivan097_img0003.jpg'
>>> print(blob_client.container_name)
'sub000'

Thanks for the feedback! We are routing this to the appropriate team for follow-up. cc @xgithubtriage.

Hi @chrisyeh96

Thanks for reporting this and post that pr. It's the SDKs problem with parsing blob url with sub directories! Sorry for the inconvenience.
