Operações de Compartilhamento

Criar Compartilhamento

share = service.create_share("my-share")

Listar Compartilhamentos

for share in service.list_shares():
    print(f"{share.name}: {share.quota} GB")

Obter Cliente de Compartilhamento

share_client = service.get_share_client("my-share")

Excluir Compartilhamento

service.delete_share("my-share")

Operações de Diretório

Criar Diretório

share_client = service.get_share_client("my-share")
share_client.create_directory("my-directory")

# Nested directory
share_client.create_directory("my-directory/sub-directory")

Listar Diretórios e Arquivos

directory_client = share_client.get_directory_client("my-directory")

for item in directory_client.list_directories_and_files():
    if item["is_directory"]:
        print(f"[DIR] {item['name']}")
    else:
        print(f"[FILE] {item['name']} ({item['size']} bytes)")

Excluir Diretório

share_client.delete_directory("my-directory")

Operações de Arquivo

Fazer Upload de Arquivo

file_client = share_client.get_file_client("my-directory/file.txt")

# From string
file_client.upload_file("Hello, World!")

# From file
with open("local-file.txt", "rb") as f:
    file_client.upload_file(f)

# From bytes
file_client.upload_file(b"Binary content")

Baixar Arquivo

file_client = share_client.get_file_client("my-directory/file.txt")

# To bytes
data = file_client.download_file().readall()

# To file
with open("downloaded.txt", "wb") as f:
    data = file_client.download_file()
    data.readinto(f)

# Stream chunks
download = file_client.download_file()
for chunk in download.chunks():
    process(chunk)

Obter Propriedades do Arquivo

properties = file_client.get_file_properties()
print(f"Size: {properties.size}")
print(f"Content type: {properties.content_settings.content_type}")
print(f"Last modified: {properties.last_modified}")

Excluir Arquivo

file_client.delete_file()

Copiar Arquivo

source_url = "https://account.file.core.windows.net/share/source.txt"
dest_client = share_client.get_file_client("destination.txt")
dest_client.start_copy_from_url(source_url)

Operações de Intervalo

Fazer Upload de Intervalo

# Upload to specific range
file_client.upload_range(data=b"content", offset=0, length=7)

Baixar Intervalo

# Download specific range
download = file_client.download_file(offset=0, length=100)
data = download.readall()

Operações de Snapshot

Criar Snapshot

snapshot = share_client.create_snapshot()
print(f"Snapshot: {snapshot['snapshot']}")

Acessar Snapshot

snapshot_client = service.get_share_client(
    "my-share",
    snapshot=snapshot["snapshot"]
)

Cliente Assíncrono

from azure.storage.fileshare.aio import ShareServiceClient
from azure.identity.aio import DefaultAzureCredential

async def upload_file():
    credential = DefaultAzureCredential()
    service = ShareServiceClient(account_url, credential=credential)
    
    share = service.get_share_client("my-share")
    file_client = share.get_file_client("test.txt")
    
    await file_client.upload_file("Hello!")
    
    await service.close()
    await credential.close()
