Downloading files with graph api

With Microsoft Graph, you can build a variety of experiences with files stored in Microsoft , from simply storing user documents to complex file-sharing scenarios. Most of the interaction with files occurs through interaction with DriveItem resources.

The following is an example of a DriveItem resource:. Drive and DriveItem resources expose data in three different ways:. In addition to addressing a DriveItem within a Drive by unique ID, your app can also address a DriveItem by relative path from a known resource. To address using a path, the colon : character is used to escape the relative path.

This table provides an example of different ways to use the colon character to address an item by path. The Drive resource is the top-level object within a user's OneDrive or a SharePoint document library. Nearly all files operations will start by addressing a specific drive resource. Here I have used a few more new classes which I will be explaining in a later section of this article, so if you get any compilation issues, ignore them for the moment.

There are two important methods in the Service class; one is storeFile , which will store the file at the required location and save the file details in the database. Before storing the file, we will check whether a user has already given the type of file available, and if it is available, then replace the latest file on a server and update the database with the latest information.

Otherwise, it will create a new entry in the database and save the file at the required location. The second method is loadFileAsResource which returns the file as a Resource on the basis of file name given. Also, we have an autowired repository object to this service which we have created in thr previous step and autowired fileStorageLocation on basis of upload-dir properties. Now let's create a controller that will handle the HTTP request and send the proper response back.
