Create OwnCloud-Strategy

[pinussilvestrus]

According to the Strategy-Pattern in our FileStorage-Service, we need an additional strategy that handles owncloud-file-servers.

Every OwnCloud-Server provides a webdav-interface. We can use this npm-module to connect to this interface.

Tasks:

• create(), creates a bucket for a school
• getFiles(), gets a list of files/ directories for a given context
• deleteFile(), deletes a file
• generateSignedUrl(), generates a url for uploading/ downloading files
• createDirectory(), creates a directory
• deleteDirectory(), deletes a directory

New! We use a new proxy DB for some file operations, so we do not always connect to the real file storage provider. Contact me for more information.
