Get a file from SharePoint Online using Microsoft Graph API

Question

While learning graph API, I was trying to get a file from a SharePoint document library using Microsoft Graph API.

I first tried by accessing files in Documents from https://graph.microsoft.com/v1.0/sites/tenant.sharepoint.com

by doing this GET request:

https://graph.microsoft.com/v1.0/sites/tenant.sharepoint.com/drive/root:/Test:/children

Everything worked great, I then tried accessing documents from another site within the same tenant. I told my self it was the same pathway while following the Microsoft docs.

I first did a test request to be sure i can first access to my site; here is what I did;

https://graph.microsoft.com/v1.0/sites/tenant.sharepoint.com:/sites/ObserveTestSite

On executing that query i got a 200 OK response.

Secondly I then tried accessing the drive Documents here is what i did;

https://graph.microsoft.com/v1.0/sites/tenant.sharepoint.com:/sites/ObserveTestSite:/drive

again everything worked fine.

I then used the root relation followed by the name of the directory and then the children relation; and this was my request:

https://graph.microsoft.com/v1.0/sites/tenant.sharepoint.com:/sites/ObserveTestSite:/drive/root:/Test:/children

But while executing that, I'm getting Bad Request - 400 - 96ms

Please help.

Thanks

I have the same issue when using site relative url to specify the specific site.

Now I'm using siteId instead and everything works as expected:

https://graph.microsoft.com/v1.0/sites/zheguo.sharepoint.com,91a47a59-db5e-4d17-a689-479ee8905533,274459c9-4c96-42bf-9b96-838ffa387aaa/drive/root:/X:/children
