Question

我正在尝试使用azure-storage-blob包动态生成blob SAS URL。 This solution仅在您拥有现已弃用的azure-storage软件包时才有效，该软件包已无法安装。

我需要一种模仿BlockBlobService.generate_blob_shared_access_signature的行为以生成Blob SAS URL的方法，如下所示：

from datetime import datetime, timedelta
from azure.storage.blob import (
    BlockBlobService,
    ContainerPermissions,
    BlobPermissions,
    PublicAccess,
)

AZURE_ACC_NAME = '<account_name>'
AZURE_PRIMARY_KEY = '<account_key>'
AZURE_CONTAINER = '<container_name>'
AZURE_BLOB='<blob_name>'

block_blob_service = BlockBlobService(account_name=AZURE_ACC_NAME, account_key=AZURE_PRIMARY_KEY)
sas_url = block_blob_service.generate_blob_shared_access_signature(AZURE_CONTAINER,AZURE_BLOB,permission=BlobPermissions.READ,expiry= datetime.utcnow() + timedelta(hours=1))
print('https://'+AZURE_ACC_NAME+'.blob.core.windows.net/'+AZURE_CONTAINER+'/'+AZURE_BLOB+'?'+sas_url)

如果您已弃用软件包，则上述解决方案有效，但是我需要不需要的解决方案。

看看下面的代码：

from datetime import datetime, timedelta
from azure.storage.blob import BlobClient, generate_blob_sas, BlobSasPermissions

account_name = 'STORAGE_ACCOUNT_NAME'
account_key = 'STORAGE_ACCOUNT_ACCESS_KEY'
container_name = 'CONTAINER_NAME'
blob_name = 'IMAGE_PATH/IMAGE_NAME'

def get_blob_sas(account_name,account_key, container_name, blob_name):
    sas_blob = generate_blob_sas(account_name=account_name, 
                                container_name=container_name,
                                blob_name=blob_name,
                                account_key=account_key,
                                permission=BlobSasPermissions(read=True),
                                expiry=datetime.utcnow() + timedelta(hours=1))
    return sas_blob

blob = get_blob_sas(account_name,account_key, container_name, blob_name)
url = 'https://'+account_name+'.blob.core.windows.net/'+container_name+'/'+blob_name+'?'+blob

请尝试以下代码：

from azure.storage.blob.sharedaccesssignature import BlobSharedAccessSignature
from datetime import datetime, timedelta

AZURE_ACC_NAME = '<account_name>'
AZURE_PRIMARY_KEY = '<account_key>'
AZURE_CONTAINER = '<container_name>'
AZURE_BLOB='<blob_name>'
expiry= datetime.utcnow() + timedelta(hours=1)

blobSharedAccessSignature = BlobSharedAccessSignature(AZURE_ACC_NAME, AZURE_PRIMARY_KEY)

sasToken = blobSharedAccessSignature.generate_blob(AZURE_CONTAINER, AZURE_BLOB, expiry=expiry, permission="r")

print sasToken
