iframe from Google Drive vs from Onedrive

[z4ch523]

I tried to embed a diagram, that is stored in OneDrive as IFrame and saw, that the complete diagram was inserted into to Code-Snippet. If I do the same with the identical diagram stored in Google Drive, the iframe instead contains a reference to the file stored in the cloud.

A sample would be "#Uhttps%3A%2F%2Fdrive.google.com%2Fuc%3Fid%3D1oD5aDAr-YfTVMwaQGi6aweLsmWqcrcaD4nvRy%26export%3Ddownload".

Why is there a fundamental difference in the way the iFrame works? This might also be related to @datdinhquoc's question here:

Thanks in advance!

OneDrive does not support permanent public URLs, so your best bet is to replace the src attribute of the iframe with the URL of the editor, replacing https://app.diagrams.net with https://viewer.diagrams.net, eg. <iframe frameborder="0" style="width:100%;height:345px;" src="https://viewer.diagrams.net/#W..."></iframe>. This will require the user to login to view the diagram.

Thanks, this solved it. Just to make sure I understood you right - this is a limitation of OneDrive rather than Drawio?

Yes, there is no public link that allows users to access the "raw" file data. If you save the file with a .drawio.png extension, in some cases, the "</> Embed" funtion in OneDrive seems to generate a link to the image. See #2073 for details.
