Download Sharepoint Excel using the Rest Api

[HGoddeau]

Working as a developer on iSeries (AS/400), I use the Rest Api's to upload/download documents to/from Sharepoint.

The tool to Get/Post messages is Axis (C++ code).

C works with "null terminated" strings and this causes problems when downloading byte streams that contain hex(00) bytes.

Is there a way to tell the Rest Api to return the byte stream as a base64 encoded stream (or as an ANSI byte stream) ?

I tried some combinations of "Accept-Charset" / "Accept-Encoding", but without succes :(

Does anybody  know a solution for this problem ?

Kind regards

Haven’t looked into it but you’ve got Azure so why not build a proxy in between using an Azure Function?

You’ll be able to turn it to base64 from there.

Just a thought.
