(VB.NET UWP/WinRT) SharePoint User Authentication (Windows classic mode authentication)

Demonstrates how to achieve Windows classic mode authentication with SharePoint. This method uses NTLM to provide the Windows credentials. The example shows how to send a GET request that returns a JSON representation of all of a site’s lists.

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

'  For example, imagine our SharePoint endpoint is https://xyzoffice.mycompany.com/
'  The SHAREPOINT_NTLM_DOMAIN would be "mycompany.com"
'  The SHAREPOINT_HTTPS_DOMAIN would be "xyzoffice.mycompany.com"

'  Also, the SHAREPOINT_USERNAME would be just the name, not a full email address.
'  for example, "chilkat" instead of "chilkat@mycompany.com"

Dim http As New Chilkat.Http

'  Provide the credentials:
http.Login = "SHAREPOINT_USERNAME"
http.Password = "SHAREPOINT_PASSWORD"
http.LoginDomain = "SHAREPOINT_NTLM_DOMAIN"
'  Tell Chilkat to use NTLM authentication.
http.NtlmAuth = True

'  Indicate that we want a JSON reply
http.Accept = "application/json;odata=verbose"

Dim sbJson As New Chilkat.StringBuilder
Dim success As Boolean = Await http.QuickGetSbAsync("https://SHAREPOINT_HTTPS_DOMAIN/_api/web/lists",sbJson)
If (success <> True) Then
    Debug.WriteLine(http.LastErrorText)
    Exit Sub
End If


Dim json As New Chilkat.JsonObject
json.LoadSb(sbJson)
json.EmitCompact = False

'  This will emit the full JSON representation of all of a site's list.
Debug.WriteLine(json.Emit())
