(Swift 3,4,5...) 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.)

Note: This example requires Chilkat v9.5.0.97 or greater.

    // 	Content-Length: <the actual content length>

    // 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 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.
