问题
Using createLink, for example with the POST parameters: {"type": "view", "scope": "anonymous"}, you get a response including a webUrl which will open the item (in read-only or read-write mode, depending on the POST parameters) in Office Online. Because of the 'anonymous' scope, anyone (no login required) can open the office online page.
Unfortunately, I don't a link to Office Online, and it looks like this is the functionality provided by Create a sharing link for a DriveItem.
I need a link to the actual file (to download it). Something like many other 'files' APIs allow. This is, generate a time-limited (or permanent) URL to file.
Is this possible?
EDIT: Clarification: Download the contents of a DriveItem (i.e. a Stream) is not what I'm looking for.
回答1:
There are four ways of linking to a file in OneDrive via Microsoft Graph:
- The web preview for the file, which is accessed from the webUrl property of DriveItem. This requires the user to be signed in to access.
- The WebDAV URL for the file, which is accessed from the webDavUrl property of DriveItem. This also requires the user to be signed in to access, but is a direct link to the file. Note: this is available via Microsoft Graph, but is only documented on dev.onedrive.com.
- Creating a sharing link, which provides anonymous or organization restricted access to the web preview of the file.
- Download link, which is a short-duration URL available to download the contents of the file programmatically.
It sounds like webDavUrl might be the link you are looking for.
