Creating shared access signature for container to upload blobs

[prashanthmadi]

Could you provide a sample to create shared access signature with new version of python SDK.

i'm trying to use my old py code and was getting below error

 from azure.storage import AccessPolicy
 from azure.storage.sharedaccesssignature import (
 SharedAccessPolicy,
 SharedAccessSignature,
 )

 DEV_STORAGE_ACCOUNT_NAME ="xxxxx"
 DEV_STORAGE_ACCOUNT_KEY ="xxxxx"
 CONTAINER_NAME='xxxxx'
 STORAGE_URL = 'xxxxx'

 def generate_signature_blob(dev_storage_account_name,dev_storage_account_key,container_name):
 sas = SharedAccessSignature(account_name=dev_storage_account_name,account_key=dev_storage_account_key)
 accss_plcy = AccessPolicy()
 accss_plcy.expiry = '2016-10-12'
 accss_plcy.permission = 'w'
 sap = SharedAccessPolicy(accss_plcy)
 sasToken = sas.generate_signed_query_string(container_name,'container',sap)
 return sas._convert_query_string(sasToken).replace("container","c")

Error :

Traceback (most recent call last):
  File "test.py", line 5, in <module>
    from azure.storage.sharedaccesssignature import
ImportError: cannot import name SharedAccessPolicy

Hi @prashanthmadi

Issue about Storage runtime have to be submitted here:

@prashanthmadi @lmazuel @xiafu-msft
I am using following code to generate container sas and access it further,
sas_token = generate_container_sas(
container_name=container_name,
permission=ContainerSasPermissions(read=True,list=True,write=True),
expiry=datetime.utcnow() + timedelta(days=1),
account_name = account_name,
account_key=account_key,
start=datetime.utcnow(),
)
print(sas_token)

but the sas token later i am using to access a blob I am getting 403.
