DropBox Filesystem Factory
--------------------------
A factory for dropbox file system.
You might need to add following config variable::
OAUTHCLIENT_REMOTE_APPS = dict(
dropbox=dict( # name of remote app used in urls
title='Dropbox', # This is used in the linked account view to
# display a name and a description.
description='Data collaboration platform.',
icon='fa fa-dropbox',
params=dict(
request_token_params={},
# usually important to define which scopes you want to request.
base_url='https://api.dropbox.com/',
request_token_url=None,
access_token_url="https://api.dropbox.com/1/oauth2/token",
authorize_url="https://www.dropbox.com/1/oauth2/authorize",
access_token_method='POST',
app_key="DROPBOX_APP_CREDENTIALS",
# defines which other config variable stores the client
# key/secret (oauth1 calls this consumer key/secret)
)
),
)
DROPBOX_APP_CREDENTIALS = dict(
consumer_key="changeme",
consumer_secret="changeme",
)
