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 DataFlex Downloads

// 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".
