在 Python 中通过 SAS 导入 azure blob

Question

编辑： 我希望通过BLOB-specific SAS 将Azure Storage Container 中的blob 导入到我的Python 脚本中。

from azure.storage.blob import BlobService

sas_service = BlobService(
    account_name = "name",
    sas_token = "mytoken"
)

blob_content = sas_service.get_blob_to_path("container_name", "blob_name")

我尝试过使用它，但它输出了一个OSError，同时列出了一个“503 错误”

根据你的描述，你想通过SAS_TOKENaccess azure blob storage。

你可以参考下面对我有用的sn-p代码：

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

accountName = "<your_account_name>"
accountKey = "<your_account_key>"
containerName = "<your_container_name>"
blobName = "<your_blob_name>"

def GetSasToken():
    blobService = BlockBlobService(account_name=accountName, account_key=accountKey)
    sas_token = blobService.generate_container_shared_access_signature(containerName,ContainerPermissions.READ, datetime.utcnow() + timedelta(hours=1))
    return sas_token


def AccessTest(token):
    blobService = BlockBlobService(account_name = accountName, account_key = None, sas_token = token)
    blobService.get_blob_to_path(containerName,blobName,"E://test.txt")


token=GetSasToken()
print token
AccessTest(token)

你也可以参考official tutorial的更多细节。

希望对你有所帮助。
