You should be able to do this in code using the Graph APIs. In particular, you'll be looking for the Working with files in Microsoft Graph section of the API documentation.
Follow these steps to install the Graph SDK.
Follow these steps to Create an app registration.
Follow these steps to Add a certificate to the app registration.
Get an auth token in your code.
Get the site ID by appending /_api/site/id to the site url e.g. https://contoso.sharepoint.com/sites/TheSite/_api/site/id
Get the list of drives associated with the document libraries on your site.
For each drive, get a list of children.
Iterate each child recursively to expand through folders and sub folders.
Download items.
Upload items to AWS.
Getting an auth token
using Azure.Identity;
var scopes = new[] { "https://graph.microsoft.com/.default" };
// Multi-tenant apps can use "common",
// single-tenant apps must use the tenant ID from the Azure portal
var tenantId = "common";
// Values from app registration
var clientId = "YOUR_APP/CLIENT_ID";
var clientCertificate = new X509Certificate2("MyCertificate.pfx");
var options = new TokenCredentialOptions
{
AuthorityHost = AzureAuthorityHosts.AzurePublicCloud
};
// https://learn.microsoft.com/dotnet/api/azure.identity.clientcertificatecredential
var clientCertCredential = new ClientCertificateCredential(
tenantId, clientId, clientCertificate, options);
var graphClient = new GraphServiceClient(clientCertCredential, scopes);
Get list of drives
var drives = await graphClient.Sites["{site-id}"].Drives
.Request()
.GetAsync();
Get root items of a drive
var children = await graphClient.Drives["{drive-id}"].Root.Children
.Request()
.GetAsync();
Get children of items
var children = await graphClient.Drives["{drive-id}"].Items["{driveItem-id}"].Children
.Request()
.GetAsync();
Download files
var stream = await graphClient.Me.Drive.Items["{driveItem-id}"].Content
.Request()
.GetAsync();
