检查blob是否在python azure中存在 [英] Checking if a blob exist in python azure

问题描述

由于azure-storage-blob的新更新，blockblobservice已弃用

Since the new update of azure-storage-blob, the blockblobservice is depreciated

如何检查blob是否存在?

How can I check that a blob exist ?

此答案不适用于新版本的azure-storage-blob 使用python进行快速Azure blob名称搜索?

This answer is not working with the new version of azure-storage-blob Faster Azure blob name search with python?

推荐答案

版本

Version 12.5.0 released on 2020-09-10 has now the exists method in the new SDK.

例如，

同步:

from azure.storage.blob import BlobClient

blob = BlobClient.from_connection_string(conn_str="my_connection_string", container_name="mycontainer", blob_name="myblob")
exists = blob.exists()
print(exists)

异步:

import asyncio

async def check():
    from azure.storage.blob.aio import BlobClient
    blob = BlobClient.from_connection_string(conn_str="my_connection_string", container_name="mycontainer", blob_name="myblob")
    async with blob:
        exists = await blob.exists()
        print(exists)
