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.)

    ; In this case, we're uploading the same JPG file but instead of providing "image/jpeg" for the

    ; 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
