Module Contents#
- class maestral.client.DropboxClient(config_name, cred_storage, timeout=100, session=None, bandwidth_limit_up=0, bandwidth_limit_down=0)[source]#
Client for the Dropbox SDK
This client defines basic methods to wrap Dropbox Python SDK calls, such as creating, moving, modifying and deleting files and folders on Dropbox and downloading files from Dropbox.
All Dropbox SDK exceptions, OSErrors from the local file system API and connection errors will be caught and reraised as a subclass of
maestral.exceptions.MaestralApiError
.This class can be used as a context manager to clean up any network resources from the API requests.
- Example:
>>> from maestral.client import DropboxClient >>> with DropboxClient("maestral") as client: ... res = client.list_folder("/") >>> print(res.entries)
- Parameters:
config_name (str) – Name of config file and state file to use.
timeout (float) – Timeout for individual requests. Defaults to 100 sec if not given.
session (requests.Session | None) – Optional requests session to use. If not given, a new session will be created with
dropbox.dropbox_client.create_session()
.bandwidth_limit_up (float) – Maximum bandwidth to use for uploads in bytes/sec. Will be enforced over all concurrent uploads (0 = unlimited).
bandwidth_limit_down (float) – Maximum bandwidth to use for downloads in bytes/sec. Will be enforced over all concurrent downloads (0 = unlimited).
cred_storage (maestral.keyring.CredentialStorage) –
- property dbx_base: _DropboxSDK[source]#
The underlying Dropbox SDK instance without namespace headers.
- Return type:
_DropboxSDK
- property dbx: _DropboxSDK[source]#
The underlying Dropbox SDK instance with namespace headers.
- Return type:
_DropboxSDK
- property linked: bool[source]#
Indicates if the client is linked to a Dropbox account (read only). This will block until the user’s keyring is unlocked to load the saved auth token.
- Raises:
KeyringAccessError – if keyring access fails.
- Return type:
- property account_info: maestral.core.FullAccount[source]#
Returns cached account info. Use
get_account_info()
to get the latest account info from Dropbox servers.- Return type:
- property namespace_id: str[source]#
The namespace ID of the path root currently used by the DropboxClient. All file paths will be interpreted as relative to the root namespace. Use
update_path_root()
to update the root namespace after the user joins or leaves a team with a Team Space.- Return type:
- property is_team_space: bool[source]#
Whether the user’s Dropbox uses a Team Space. Use
update_path_root()
to update the root namespace after the user joins or eaves a team with a Team Space.- Return type:
- get_auth_url()[source]#
Returns a URL to authorize access to a Dropbox account. To link a Dropbox account, retrieve an authorization code from the URL and link Maestral by calling
link()
with the provided code.- Returns:
URL to retrieve an authorization code.
- Return type:
- link(code=None, refresh_token=None, access_token=None)[source]#
Links Maestral with a Dropbox account using the given authorization code. The code will be exchanged for an access token and a refresh token with Dropbox servers. The refresh token will be stored for future usage in the provided credential store.
- Parameters:
code (str | None) – Authorization code.
refresh_token (str | None) – Optionally, instead of an authorization code, directly provide a refresh token.
access_token (str | None) – Optionally, instead of an authorization code or a refresh token, directly provide an access token. Note that access tokens are short-lived.
- Returns:
0 on success, 1 for an invalid token and 2 for connection errors.
- Return type:
- unlink()[source]#
Unlinks the Dropbox account. The password will be deleted from the provided credential storage.
- Raises:
KeyringAccessError – if keyring access fails.
DropboxAuthError – if we cannot authenticate with Dropbox.
- Return type:
None
- close()[source]#
Cleans up all resources like the request session/network connection.
- Return type:
None
- update_path_root(root_info)[source]#
Updates the root path for the Dropbox client. All files paths given as arguments to API calls such as
list_folder()
orget_metadata()
will be interpreted as relative to the root path. All file paths returned by API calls, for instance in file metadata, will be relative to this root path.The root namespace will change when the user joins or leaves a Dropbox Team with Team Spaces. If this happens, API calls using the old root namespace will raise a
maestral.exceptions.PathRootError
. Use this method to update to the new root namespace.See https://developers.dropbox.com/dbx-team-files-guide and https://www.dropbox.com/developers/reference/path-root-header-modes for more information on Dropbox Team namespaces and path root headers in API calls.
Note
We don’t automatically switch root namespaces because API users may want to take action when the path root has changed before making further API calls. Be prepared to handle
maestral.exceptions.PathRootError
and act accordingly for all methods.- Parameters:
root_info (maestral.core.RootInfo) –
core.RootInfo
describing the path root. Useget_account_info()
to retrieve.- Return type:

- Returns:
Account info.
- get_metadata(dbx_path, include_deleted=False)[source]#
Gets metadata for an item on Dropbox or returns
False
if no metadata is available. Keyword arguments are passed on to Dropbox SDK files_get_metadata call.- Parameters:

Metadata of item at the given path or
None
if item cannot be found.- Return type:
maestral.core.Metadata | None
- list_revisions(dbx_path, mode='path', limit=10)[source]#

- download(dbx_path, local_path, sync_event=None)[source]#
Downloads a file from Dropbox to given local path.
- Parameters:
dbx_path (str) – Path to file on Dropbox or rev number.
local_path (str) – Path to local download destination.
sync_event (maestral.models.SyncEvent | None) – If given, the sync event will be updated with the number of downloaded bytes.

- Return type:
- upload(local_path, dbx_path, write_mode=WriteMode.Add, update_rev=None, autorename=False, sync_event=None)[source]#
Uploads local file to Dropbox. If the file size is smaller than 4 MB, the file will be uploaded all at once. Otherwise, the file will be loaded into memory and uploaded in chunks of 4 MB. If the file is modified during this chunked upload, this will raise a
DataChangedError
.- Parameters:
local_path (str) – Path of local file to upload.
dbx_path (str) – Path to save file on Dropbox.
write_mode (maestral.core.WriteMode) –
Your intent when writing a file to some path. This is used to determine what constitutes a conflict and what the autorename strategy is. This is used to determine what constitutes a conflict and what the autorename strategy is. In some situations, the conflict behavior is identical: (a) If the target path doesn’t refer to anything, the file is always written; no conflict. (b) If the target path refers to a folder, it’s always a conflict. (c) If the target path refers to a file with identical contents, nothing gets written; no conflict. The conflict checking differs in the case where there’s a file at the target path with contents different from the contents you’re trying to write.
core.WriteMode.Add
Do not overwrite an existing file if there is aconflict. The autorename strategy is to append a number to the file name. For example, “document.txt” might become “document (2).txt”.
core.WriteMode.Overwrite
Always overwrite the existing file. Theautorename strategy is the same as it is for
add
.core.WriteMode.Update
Overwrite if the given “update_rev” matchesthe existing file’s “rev”. The supplied value should be the latest known “rev” of the file, for example, from
core.FileMetadata
, from when the file was last downloaded by the app. This will cause the file on the Dropbox servers to be overwritten if the given “rev” matches the existing file’s current “rev” on the Dropbox servers. The autorename strategy is to append the string “conflicted copy” to the file name. For example, “document.txt” might become “document (conflicted copy).txt” or “document (Panda’s conflicted copy).txt”.
update_rev (str | None) – Rev to match for
core.WriteMode.Update
.sync_event (maestral.models.SyncEvent | None) – If given, the sync event will be updated with the number of downloaded bytes.
autorename (bool) – If there’s a conflict, as determined by
mode
, have the Dropbox server try to autorename the file to avoid conflict. The default for this field is False.
- Returns:
Metadata of uploaded file.
- Raises:
DataCorruptionError – if data is corrupted during upload.
DataChangedError – if the file is modified during a chunked upload.
