Upload file to SharePoint drive using Microsoft Graph

Question

We are trying to implement integration between a web application and SharePoint Online using Microsoft Graph rest API.

Specifically, we need to upload a file to a specific SharePoint site's document library (drive), different than current user default drive. We get the access token through Azure AD with access to all files.

We can upload files into any drive using /v1.0/me/drive/... but not when we use another drive.

For example:

var response = client.PutAsync(graphResourceUrl +
    "/beta/sharepoint/sites/" + siteCollSiteId +
    "/lists/" + listId +
    "/drive/root/children/" + fileName + ":/content",
    new ByteArrayContent(fileBytes)).Result;

var response = client.PutAsync(graphResourceUrl +
    "/beta/drives/" + "/" + listId +
    "/items/" + siteCollSiteId + "/" + fileName + ":/content",
    new ByteArrayContent(fileBytes)).Result;

var response = client.PutAsync(graphResourceUrl +
    "/beta/drives/" + listId + "/" + fileName + ":/content",
    new ByteArrayContent(fileBytes)).Result;

Both /v1.0 and /beta (in the case of SharePoint containing path) we are getting an error response of Not Implemented .

What could we be doing wrong? Is it not yet working with Microsoft Graph (other than /me )?

Answer 1

In order to get all the files of a drive using v1.0, you would first need to get an access token (which I see you are already passed that), then get the 'drive-id' and use the following URL(note: its not 'drive' it is 'drives'):

https://graph.microsoft.com/v1.0/drives/{drive-id}/root/children

To get the drive id, I made the following GET request using postman, this will list all the drives on the site and you will be able to get the ID of that drive:

https://graph.microsoft.com/v1.0/sites/{tenant}.sharepoint.com:{path-to-site(ie: /sites/HR)}:/drives

To answer your question regarding Uploading files, you will make a PUT request to the following URL:

https://graph.microsoft.com/v1.0/drives/{drive-id}/root:/{folder-name}/{file-name.txt}:/content

You will need to set two required headers:

• Authorization
• Content-Type

Next, you will pass the binary stream of the file into the body of the request.

从:/content删除:通常，对我来说最好先获取sp库的driveId，然后再使用/v1.0/drive/{driveId}/在v1.0端点上工作
