ShareFileClient

Constructor

ShareFileClient(account_url: str, share_name: str, file_path: str, snapshot: str | Dict[str, Any] | None = None, credential: str | Dict[str, str] | AzureNamedKeyCredential | AzureSasCredential | TokenCredential | None = None, *, token_intent: Literal['backup'] | None = None, **kwargs: Any)

Parameters

Name Description
account_url
Required
str

The URI to the storage account. In order to create a client given the full URI to the file, use the from_file_url classmethod.
share_name
Required
str

The name of the share for the file.
file_path
Required
str

The file path to the file with which to interact. If specified, this value will override a file value specified in the file URL.
snapshot
str

An optional file snapshot on which to operate. This can be the snapshot ID string or the response returned from create_snapshot.

Default value: None
credential
AzureNamedKeyCredential or AzureSasCredential or TokenCredential or str or dict[str, str] or None

The credentials with which to authenticate. This is optional if the account URL already has a SAS token. The value can be a SAS token string, an instance of a AzureSasCredential or AzureNamedKeyCredential from azure.core.credentials, an account shared access key, or an instance of a TokenCredentials class from azure.identity. If the resource URI already contains a SAS token, this will be ignored in favor of an explicit credential

  • except in the case of AzureSasCredential, where the conflicting SAS tokens will raise a ValueError. If using an instance of AzureNamedKeyCredential, "name" should be the storage account name, and "key" should be the storage account key.
Default value: None

Keyword-Only Parameters

Name Description
token_intent
Literal['backup']

Required when using TokenCredential for authentication and ignored for other forms of authentication. Specifies the intent for all requests when using TokenCredential authentication. Possible values are:

backup - Specifies requests are intended for backup/admin type operations, meaning that all file/directory ACLs are bypassed and full permissions are granted. User must also have required RBAC permission.

If true, the trailing dot will not be trimmed from the target URI.
allow_source_trailing_dot
bool

If true, the trailing dot will not be trimmed from the source URI.

max_range_size
int

The maximum range size used for a file upload. Defaults to 4*1024*1024.

Methods

abort_copy

Abort an ongoing copy operation.

This will leave a destination file with zero length and full metadata. This will raise an error if the copy operation has already ended.
acquire_lease

Requests a new lease.

If the file does not have an active lease, the File Service creates a lease on the blob and returns a new lease.
clear_range

Clears the specified range and releases the space used in storage for that range.
close

This method is to close the sockets opened by the client. It need not be used when using with a context manager.
close_all_handles

Close any open file handles.

This operation will block until the service has closed all open handles.
close_handle

Close an open file handle.
create_file

Creates a new file.

Note that it only initializes the file with no content.
delete_file

Marks the specified file for deletion. The file is later deleted during garbage collection.
download_file

Downloads a file to the StorageStreamDownloader. The readall() method must be used to read all the content or readinto() must be used to download the file into a stream. Using chunks() returns an iterator which allows the user to iterate over the content in chunks.
exists

Returns True if the file exists and returns False otherwise.
from_connection_string

Create ShareFileClient from a Connection String.
from_file_url

A client to interact with a specific file, although that file may not yet exist.
get_file_properties

Returns all user-defined metadata, standard HTTP properties, and system properties for the file.

start_copy_from_url

Initiates the copying of data from a source URL into the file referenced by the client.

The status of this copy operation can be found using the get_properties method.
