GET file with correct name

Question

I'm working on a Word add-in with a form for selecting SharePoint Online documents, using the REST API.
At the moment, I was able to download the file directly by the URL following this MSDN article:

https://....com/sites/site/_api/Web/GetFileByServerRelativePath(decodedurl='/sites/site/folder/Test.docx')/$value

However, this downloads the file with the name $value instead of the correct filename. Is it possible to get the actual name through REST?

Answer 1

Because when you download the file by the REST API, you just get the stream of the file even though you have downloaded the file.

https://....com/sites/site/_api/Web/GetFileByServerRelativePath(decodedurl='/sites/site/folder/Test.docx')/$value

I suggest you could get the stream of the file by the REST API and save the file to the local with the correct file through the JavaScript code.
