    local_dir='data/',
    remote_dir='/testfolder',
    add_date=True,
    add_date_recursive=False
)

Nextcloud

API documentation: https://docs.nextcloud.com/server/latest/developer_manual/client_apis/index.html

App password

It is recommended not to use your login password. You can create app specific passwords: Settings -> security -> new app password.

Usage

from mpg_cloud import Nextcloud
cloud = Nextcloud(
    server='https://SERVERNAME/remote.php/dav/files/',
    username=USERNAME, 
    password=PASSWORD, 
    webdav_token=WEBDAV_TOKEN
    )

In the official nextcloud documentation the webdav_token is referred to as "username". But it is different from the login name and can be found in settings -> WebDAV.

List files/folders

list root directory

cloud.list('')

list https://SERVERNAME/apps/files/?dir=/WebdavTest/subfolder

cloud.list_dir('WebdavTest/subfolder')

Make Dir

Create directory named New in WebdavTest

cloud.make_dir('WebdavTest/neu')

Upload file

Upload Datei.md from the local dir data/ to WebdavTest/subfolder. If add_date is True a timestamp will be added to the filename.

cloud.upload_file(
    local_file='data/Datei.md', 
    path='WebdavTest/subfolder', 
    filename='Datei1.md',
    add_date=True
    )

Upload folder

Upload the local folder ./Testfolder into the WebdavTest folder on Nextcloud. Add a timestamp to the foldername if add_date is True. Add a timestamp to all files in the folder if add_date_recursive is True.

cloud.upload_folder(
    local_folder='Testfolder', 
    target_folder='WebdavTest', 
    add_date=True, 
    add_date_recursive=False)

Download file

cloud.download_file(
    path='WebdavTest/', 
    filename='kwg_mpg.xlsx', 
    target_dir='data/'
    )

Read file

Read Excel file from Nextcloud.

import pandas as pd
df = pd.read_excel(
    cloud.read_file(path='WebdavTest/', filename='kwg_mpg.xlsx'), engine='openpyxl'
    )

Read CSV

import pandas as pd
from io import BytesIO
csv = cloud.read_file(path='WebdavTest/Subfolder/', filename='datei.csv')
df = pd.read_csv(BytesIO(csv))
