Sample onedrive winforms app vb.net

Question

I've been searching the net for a basic sample winforms app that is written in vb.net to upload a file to onedrive. Does anyone know of any?

I'm trying to get a file uploaded with a winforms app in vb.net. I'm as far as getting the auth working... but calling the next method returns a 401...

I did the following:

Shared scope As String = "wl.skydrive_update" Shared client_id As String = "0000000040144E26" Shared signInUrl As New Uri([String].Format("https://login.live.com/oauth20_authorize.srf?client_id={0}&redirect_uri=https://login.live.com/oauth20_desktop.srf&response_type=code&scope={1}", client_id, scope))

Private Sub cmdOneDriveAuth_Click(sender As Object, e As EventArgs) Handles cmdOneDriveAuth.Click Try Dim auth As New FrmAuthBrowser auth.WebBrowser1.Navigate(signInUrl) auth.Show()

    Catch ex As Exception

    End Try
End Sub

and then in the auth window:

Private Sub WebBrowser1_DocumentCompleted(sender As Object, e As Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
    Try
        If WebBrowser1.Url.AbsoluteUri.Contains("code=") Then
            Dim AuthCode As String = System.Web.HttpUtility.ParseQueryString(WebBrowser1.Url.Query)("code")
            My.Settings.OneDrive_Enabled = True
            My.Settings.OneDrive_AuthCode = AuthCode
            My.Settings.Save()
            Me.Dispose()
        End If


    Catch ex As Exception
        MsgBox(ex.ToString)
    End Try
End Sub

but when I try and get the root info, I get a 401...

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click Try Dim client As New WebClient() Dim result = client.OpenRead(New Uri("https://apis.live.net/v5.0/me/skydrive?access_token=" + My.Settings.OneDrive_AuthCode)) Dim sr As StreamReader = New StreamReader(result) MsgBox(sr.ReadToEnd()) Catch ex As Exception MsgBox(ex.ToString) End Try End Sub

Can anyone provide me with some guidance?

Looks like you're using the 'code' flow of OAuth, but you're missing a step. The 'code' you get back isn't the same as the access_token. You need to make another call to the login server first to exchange your code for an access_token.

POST https://login.live.com/oauth20_token.srf
Content-Type: application/x-www-form-urlencoded

client_id={client_id}&redirect_uri={redirect_uri}&client_secret={client_secret}
&code={code}&grant_type=authorization_code

You can find more details here http://onedrive.github.io/auth/msa_oauth.htm#code-flow.

OneDrive just released a new API, so I would encourage you to check it out. http://onedrive.github.io/

There's also a sample Windows/C# app that you can look at for reference on how to sign in and upload files. https://github.com/OneDrive/onedrive-explorer-win
