Response

Returns a 302 Found response redirecting to a preauthenticated download URL for the file, which is the same URL available through the @microsoft.graph.downloadUrl property on the DriveItem.

To download the contents of the file your application needs to follow the Location header in the response. Many HTTP client libraries will automatically follow the 302 redirection and start downloading the file immediately.

Preauthenticated download URLs are only valid for a short period of time (a few minutes) and don't require an Authorization header to download.

HTTP/1.1 302 Found
Location: https://b0mpua-by3301.files.1drv.com/y23vmagahszhxzlcvhasdhasghasodfi

Downloading files in JavaScript apps

To download files in a JavaScript app, you can't use the /content API, because this responds with a 302 redirect. A 302 redirect is explicitly prohibited when a Cross-Origin Resource Sharing (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 directs to. This URL can then be requested directly using XMLHttpRequest. Because these URLs are preauthenticated, they can be retrieved without a CORS preflight request.

Example

To retrieve the download URL for a file, first make a request that includes the @microsoft.graph.downloadUrl property:

GET /drive/items/{item-ID}?select=id,@microsoft.graph.downloadUrl

The call returns the ID and download URL for a file:

HTTP/1.1 200 OK
Content-Type: application/json

{
  "id": "12319191!11919",
  "@microsoft.graph.downloadUrl": "https://..."
}

You can then make an XMLHttpRequest for the URL provided in @microsoft.graph.downloadUrl to retrieve the file.

Partial range downloads

To download a partial range of bytes from the file, your app can use the Range header as specified in RFC 2616. You must append the Range header to the actual @microsoft.graph.downloadUrl URL and not to the request for /content.

GET https://b0mpua-by3301.files.1drv.com/y23vmag
Range: bytes=0-1023

The call returns an HTTP 206 Partial Content response with the request range of bytes from the file. If the range can't be generated the Range header may be ignored and an HTTP 200 response would be returned with the full contents of the file.

HTTP/1.1 206 Partial Content
Content-Range: bytes 0-1023/2048
Content-Type: application/octet-stream

<first 1024 bytes of file>
