(Visual FoxPro) OneDrive -- Upload Binary Data from Memory

See more OneDrive Examples

Demonstrates how to upload binary data directly from memory to the signed-in user's OneDrive. This uses OneDrive's simple upload API to upload in a single API call, which only supports uploads up to 4MB in size. (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"

* First, let's download a PDF from the web directly into memory.  Then upload the PDF
* to OneDrive.
loPdfBytes = CreateObject('Chilkat_9_5_0.BinData')
lnSuccess = loHttp.QuickGetBd("https://www.chilkatsoft.com/data/pdf/sample.pdf",loPdfBytes)
IF (lnSuccess <> 1) THEN
    ? loHttp.LastErrorText
    RELEASE loHttp
    RELEASE loPdfBytes
    CANCEL
ENDIF

* Upload the PDF to our OneDrive to /someFolder/sample.pdf
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/sample.pdf:/content"
loReq.LoadBodyFromBd(loPdfBytes)
* If you're uploading a file and don't know what the Content-Type should be,
* just use "application/octet-stream".  
loReq.ContentType = "application/pdf"

loResp = loHttp.SynchronousRequest("graph.microsoft.com",443,1,loReq)
IF (loHttp.LastMethodSuccess <> 1) THEN
    ? loHttp.LastErrorText
    RELEASE loHttp
    RELEASE loPdfBytes
    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
    ? loJson.Emit()
    ? "Response status = " + STR(loResp.StatusCode)
    RELEASE loResp
    RELEASE loHttp
    RELEASE loPdfBytes
    RELEASE loReq
    RELEASE loJson
    CANCEL
ENDIF

RELEASE loResp

* Success.  Examine the driveItem JSON object:
? loJson.Emit()
? "-- Success --"

* Here is a sample successful response:
