VB.NET Requires Chilkat v11.0.0+

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.) VB.NET

Dim success As Boolean = False

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

'  This example uses the OAuth client credentials flow.
'  See How to Create an Azure App Registration for OAuth 2.0 Client Credentials

'  Use your client ID, client secret, and tenant ID in the following lines
Dim json As New Chilkat.JsonObject
json.UpdateString("client_id","2871da2c-8176-4b7f-869b-2311aa82e743")
json.UpdateString("client_secret","2hu9Q~r5QuryUcEkNbg1btLtnfU1VUXzhSCG6brH")
json.UpdateString("scope","https://graph.microsoft.com/.default")
json.UpdateString("token_endpoint","https://login.microsoftonline.com/114d7ed6-71bf-4dbe-a866-748364121bf2/oauth2/v2.0/token")

Dim http As New Chilkat.Http
http.AuthToken = json.Emit()

'  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: 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 /TestDir/location.xml
http.SetUrlVar("dest_path","/TestDir/location.xml")
http.SetUrlVar("user_id","4fe732c3-322e-4a6b-b729-2fd1eb5c6104")
Dim url As String = "https://graph.microsoft.com/v1.0/users/{$user_id}/drive/root:{$dest_path}:/content"

Dim resp As New Chilkat.HttpResponse
success = http.HttpStr("PUT",url,someString,"utf-8","application/xml",resp)
If (success = False) 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.
json.EmitCompact = False
resp.GetBodyJson(json)

If (resp.StatusCode <> 201) Then

    Debug.WriteLine(json.Emit())
    Debug.WriteLine("Response status = " & resp.StatusCode)

'  Success.  Examine the driveItem JSON object:
