如何在Python中生成Azure Blob SAS URL? [英] How can I generate an Azure blob SAS URL in Python?

问题描述

我正在尝试使用 azure-storage-blob 包动态生成blob SAS URL.此解决方案仅在您拥有现已弃用的 azure-storage 软件包时有效.已经安装了.

I am trying to generate blob SAS URLs on the fly using the azure-storage-blob package. This solution only works if you have the now-deprecated azure-storage package, which cannot be installed anymore.

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

I need a way to mimic the behaviour of BlockBlobService.generate_blob_shared_access_signature to generate a blob SAS URL, like this:

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.

The above solution works if you have the deprecated package, but I need a solution which doesn't need it.

推荐答案

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

您可以在此处了解有关使用新的Storage SDK生成SAS令牌的更多信息:
