在存储帐户 python天蓝色函数之间移动或复制文件blob？

问题描述

我想使用 python（在 azure 函数中）在两个存储帐户之间移动（或复制然后删除）文件/blob。我使用过 this 之类的方法。 但是这适用于旧的 SDK，有人知道新 SDK 的方法吗？

类似于 this 但在两个存储帐户而不是容器之间。

解决方法

如果要跨Azure存储账户复制blob，请参考以下代码

from azure.storage.blob import ResourceTypes,AccountSasPermissions,generate_account_sas,BlobServiceClient
from datetime import datetime,timedelta
source_key = ''
des_key = ''
source_account_name = ''
des_account_name = '23storage23'
# genearte account sas token for source account
sas_token = generate_account_sas(account_name=source_account_name,account_key=source_key,resource_types=ResourceTypes(
                                     service=True,container=True,object=True),permission=AccountSasPermissions(read=True),expiry=datetime.utcnow() + timedelta(hours=1))
source_blob_service_client = BlobServiceClient(
    account_url=f'https://{source_account_name}.blob.core.windows.net/',credential=source_key)
des_blob_service_client = BlobServiceClient(
    account_url=f'https://{des_account_name}.blob.core.windows.net/',credential=des_key)

source_container_client = source_blob_service_client.get_container_client(
    'copy')

source_blob = source_container_client.get_blob_client('Capture.PNG')
source_url = source_blob.url+'?'+sas_token
# copy
des_blob_service_client.get_blob_client(
    'test',source_blob.blob_name).start_copy_from_url(source_url)

另外，如果源容器的访问级别为public，我们可以将代码简化如下

from azure.storage.blob import BlobServiceClient
source_key = ''
des_key = ''
source_account_name = ''
des_account_name = '23storage23'
source_blob_service_client = BlobServiceClient(
    account_url=f'https://{source_account_name}.blob.core.windows.net/',credential=des_key)

source_container_client = source_blob_service_client.get_container_client(
    'input')

source_blob = source_container_client.get_blob_client('file.json')
source_url = source_blob.url
# copy
des_blob_service_client.get_blob_client(
    'test',source_blob.blob_name).start_copy_from_url(source_url)
