OneDrive -- Streaming File Upload
See more OneDrive Examples
Uploads a local file by path to the signed-in user's OneDrive. This uses OneDrive's simple upload API to upload in a single API call. Uploading in this way only supports files up to 4MB in size. The 4MB limitation is a OneDrive limitation, not a Chilkat limitation. (See the other example(s) for uploading larger files.)Chilkat PureBasic Downloads

; Now let's upload some file where we don't know what the Content-Type should be.
;
; In this case, we're uploading the same JPG file but instead of providing "image/jpeg" for the
; Content-Type, we provide "application/octet-stream". ("application/octet-stream" is the general
; HTTP content-type used for anything unkown. "octet" is a synonym for "byte". It's just a way of
; saying: Here's a stream of bytes that comprise the file.)
; Also, you'll notice in the successful JSON response (below), that Microsoft automatically
; detected the Content-Type as "image/jpeg", because the mimeType is set as such.
; It is likely Microsoft set the MIME type (i.e. Content-Type) based on the file extension, or even better
; it may have determined the MIME type by examining the initial bytes of the file to find the standard
; identifying markers that signify common file types such as PDF, JPG, ZIP, and many more.
; In a nutshell: Don't worry about setting the ContentType precisely. If you know it, great. If not, just
; use "application/octet-stream".
