gdrive-fsspec 0.2.0

File system on GDrive

Google Drive fsspec implementation

This is an implementation of the fsspec interface for Google Drive.

This software is in beta stage and should not be relied upon in production settings.

Installation

You can install it with pip from pypi or directly from source:

pip install gdrive_fsspec
pip install git+https://github.com/fsspec/gdrivefs

Usage

As gdrivefs implements the fsspec interface, most documentation can be found at https://filesystem-spec.readthedocs.io/en/latest/usage.html.

Authentication

There are several methods to authenticate gdrivefs against Google Drive.

1. Service account credentials

In this method, you provide a dict containing the service account credentials obtained in the GCP console. The dict content is the same as the JSON file downloaded from the GCP console. More details can be found here: https://cloud.google.com/iam/docs/service-account-creds#key-types. This credential can be useful when integrating with other GCP services, and when you don't want the user to be prompted to authenticate.

from gdrive_fsspec import GoogleDriveFileSystem
fs = GoogleDriveFileSystem(creds=service_account_credentials)

2. OAuth with user credentials

A browser will be opened to complete the OAuth authentication flow. Afterwards, the access token will be stored locally, and you can reuse it in subsequent sessions.

# use this the first time you run
token = 'browser'
# use this on subsequent attempts
# token = 'cache'
fs = GoogleDriveFileSystem(token=token)

3. Anonymous (read-only) access

If you want to interact with files that are shared publicly ("anyone with the link"), then you do not need to authenticate to Google Drive.

token = 'anon'
fs = GoogleDriveFileSystem(token=token)

See GoogleDriveFileSystem docstring for more details.

Development

Running tests

Unit tests

pip install -e . pytest
pytest -v

Integration tests

To run integration tests, you need to have user credentials cached locally that can be used to interact with your real Google Drive account. You can do this by running the following:

import gdrive_fsspec
fs = gdrive_fsspec.GoogleDriveFileSystem(token='browser')

Alternatively, you can save user credentials in a file and set the environment variable GDRIVEFS_USER_CREDENTIALS_PATH to the path of the file.

Then you can run the integration tests:

pytest -v -m integration

Other implementations

• PyDrive2 also provides an fsspec-compatible Google Drive API.
