通过 Azure notebook 从 blob 容器访问 csv 文件

Question

我想使用 Azure Python 笔记本从 blob 存储中的容器访问一个大小约为 2GB 的文件，但由于某种原因我遇到了这个错误。

权限错误：[Errno 13] 权限被拒绝：'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

Answer 1

我已经添加了存储帐户 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
