(Visual FoxPro) 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 v9.5.0.68 or greater.

* This example requires the Chilkat API to have been previously unlocked.
* See Global Unlock Sample for sample code.

loHttp = CreateObject('Chilkat_9_5_0.Http')

* Use your previously obtained access token here:
* See the following examples for getting an access token:
*    Get Microsoft Graph OAuth2 Access Token (Azure AD v2.0 Endpoint).
*    Get Microsoft Graph OAuth2 Access Token (Azure AD Endpoint).
*    Refresh Access Token (Azure AD v2.0 Endpoint).
*    Refresh Access Token (Azure AD Endpoint).

* (Make sure your token was obtained with the Files.ReadWrite scope.)
loHttp.AuthToken = "MICROSOFT_GRAPH_ACCESS_TOKEN"

* To upload in a single HTTP request, send a PUT request such as the following:

* 	PUT /v1.0/me/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.

loReq = CreateObject('Chilkat_9_5_0.HttpRequest')
loReq.HttpVerb = "PUT"
* If not using "me", then the path should be /v1.0/users/{id | userPrincipalName}/...
loReq.Path = "/v1.0/me/drive/root:/someFolder/penguins.jpg:/content"
* 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..
loReq.ContentType = "image/jpeg"

loResp = loHttp.SynchronousRequest("graph.microsoft.com",443,1,loReq)
IF (loHttp.LastMethodSuccess <> 1) THEN
    ? loHttp.LastErrorText
    RELEASE loHttp
    RELEASE loReq
    CANCEL
ENDIF

* If successful, a 201 status code is returned, with the driveItem object in the response body for the newly created file.
loJson = CreateObject('Chilkat_9_5_0.JsonObject')
loJson.EmitCompact = 0
loJson.Load(loResp.BodyStr)

IF (loResp.StatusCode <> 201) THEN

    * Here is an example of an error:

    * 		{
    * 		  "error": {
    * 		    "code": "nameAlreadyExists",
    * 		    "message": "An item with the same name already exists under the parent",

* ------------------------------------------------------------------------------------
* 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".
