(VB.NET UWP/WinRT) OneDrive -- Upload a String

See more OneDrive Examples

Uploads a string 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.

Dim http As New Chilkat.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.)
http.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: Chilkat automatically adds the Content-Length header.

' This example will upload a string that happens to be XML.
Dim someString As String = "<location><city>Chicago</city><state>IL</state></location>"
' Upload to /someFolder/location.xml
http.SetUrlVar("dest_path","/someFolder/location.xml")
' If not using "me", then the path part of the URL should be /v1.0/users/{id | userPrincipalName}/...
Dim url As String = "https://graph.microsoft.com/v1.0/me/drive/root:{$dest_path}:/content"

Dim resp As String = Await http.PutTextAsync(url,someString,"utf-8","application/xml",False,False)
If (http.LastMethodSuccess <> True) Then
    Debug.WriteLine(http.LastErrorText)
    Exit Sub
End If


' If successful, a 201 status code is returned, with the driveItem object in the resp body for the newly created file.
Dim json As New Chilkat.JsonObject
json.EmitCompact = False
json.Load(resp)

If (http.LastStatus <> 201) Then

    Debug.WriteLine(json.Emit())
    Debug.WriteLine("Response status = " & http.LastStatus)
    Exit Sub
End If


' Success.  Examine the driveItem JSON object:
Debug.WriteLine(json.Emit())
Debug.WriteLine("-- Success --")

' Here is a sample successful response:
