onedrive-api | official middle-level HTTP API bindings | REST library

I want to create a simple Python utility that interacts with files on OneDrive. Right now I'm using my company account (so I have no access to admin settings or any detailed insight into OneDrive/Sharepoint/Azure configuration).

After quick googling session it seemed that Microsoft Graph is the way to go. I started with copying the sample app and once I verified that basic functionality is working (it shows the name from my profile, etc.) I tried adding a simple call to me/drive/root/children in order to list files in the root directory. And I am unable to get it working.

No matter what I do, server returns the following:

After a time I finally figure out how to use oAuth2 and how to create a access token with the refresh token. But I can´t find node.js samples for upload files the only thing I found was this module https://www.npmjs.com/package/onedrive-api

But this didn´t work for me because I get this error { error: { code: 'unauthenticated', message: 'Authentication failed' } }

Also if I would enter accessToken: manually with 'xxxxxxx' the result would be the same.

But I created before the upload the access token so I don´t know if this really can be a invalid credits problem. But the funny thing is if I would take the access token from https://dev.onedrive.com/auth/msa_oauth.htm where you can generate a 1h access token the upload function works. I created my auth with the awnser from this question. OneDrive Code Flow Public clients can't send a client secret - Node.js
Also I only used the scope Files.readWrite.all do I maybe need to allow some other scopes ? My code is

I try to download several files from OneDrive through Microsoft Graph.

I am very close to achieve my goal. For the moment I have managed the token system (notably through Jay Lee detailed answer), and achieved to resolve the confusion that I made among the different endpoints that exist in Microsoft Graph (thank you Marc LaFleur - MSFT).

Now I really work on the call of the API that would permit to download the files I want. This is how I proceeded:

1- As I've seen in the Microsoft Graph Documentation, the normal syntax would be the following:

curl -w %{time_total} https://graph.microsoft.com/v1.0/me/drive/items/01M...WU/content -H "Authorization: Bearer $access_token"

2- However, this gives me a 302 request, which I can't handle in bash. So I looked for another solution and I found this Microsoft article explaining that:

"To download files from OneDrive in a JavaScript app you cannot use the /content API, since this responds with a 302 redirect. A 302 redirect is explicitly prohibited when a CORS preflight is required, such as when providing the Authorization header.

Instead, your app needs to select the @microsoft.graph.downloadUrl property, which returns the same URL that /content would have redirected to. This URL can then be requested directly using XMLHttpRequest. Because these URLs are pre-authenticated they can be retrieved without a CORS preflight request."

It talks about Javascript but I think it can be applied to my case.

3- So I tried this method and I wrote:

curl "https://graph.microsoft.com/v1.0/me/drive/items/01MB...WU?select=id,@microsoft.graph.downloadUrl" -H "Authorization: Bearer $access_token"

It gave me the URL that normally would permit me to finally download the file, but when I execute it, I get the following response:

Code:

curl "https://graph.microsoft.com/v1.0/$metadata#users('e967dd4d-680e-4a06-9bf7-468875e1a04c')/drive/items/$entity" -H "Authorization: Bearer $access_token" (it is exactly what I got with the previous request)

Response:

Any help? Why is it a bad request since I've put exactly what I got from the graph.microsoft.com request?
