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 Visual FoxPro Downloads

* This example requires the Chilkat API to have been previously unlocked.

* Use your client ID, client secret, and tenant ID in the following lines

* To upload in a single HTTP request, send a PUT request such as the following:
* PUT /v1.0/users/{$user-id}/drive/root:/{item-path}:/content
* Content-type: text/plain
* Content-Length: <the actual content length>
*
* The contents of the file goes here.
* Note: This example can upload any type of file.
* Chilkat automatically adds the Content-Length header.

* Indicate the local file to be streamed in the upload.
loReq.StreamBodyFromFile("qa_data/jpg/penguins.jpg")
* If you're uploading a file and don't know what the Content-Type should be,
* just use "application/octet-stream". See below for an example..

* 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".
