【问题描述】：

我想使用 Azure Python 笔记本从 Blob 存储中的容器访问大小约为 2GB 的文件，但由于某种原因，我遇到了这个错误。

PermissionError: [Errno 13] Permission denied: 'part-00000-tid-9128541598398997257-8ae9f3ab-ad94-4ed6-ac2d-91b488393378-72-1-c000.csv'

Here is the snippet of code that worked for me before, but for some reason is not working now

【解决方案1】：

我已包含存储帐户 URL，它对我有用。这是供您参考的代码

from azure.storage.blob import BlobServiceClient
import pandas as pd

STORAGEACCOUNTNAME= "<Storage account Name>"
STORAGEACCOUNTKEY= "<Storage account key>"
LOCALFILENAME= "<Local file name>"
CONTAINERNAME= "<Container name>"
BLOBNAME= "<blob name>"
STORAGEACCOUNTURL="https://<storage account name>.blob.core.windows.net"

#To download the blob
blob_service_client_instance = BlobServiceClient(account_url=STORAGEACCOUNTURL, credential=STORAGEACCOUNTKEY)
blob_client_instance = blob_service_client_instance.get_blob_client(CONTAINERNAME, BLOBNAME, snapshot=None)
with open(LOCALFILENAME, "wb") as my_blob:
    blob_data = blob_client_instance.download_blob()
    blob_data.readinto(my_blob)

#Read the blob
dataframe_blobdata = pd.read_csv(LOCALFILENAME)
print(dataframe_blobdata)

这是输出
