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

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.Http")
set http = Server.CreateObject("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).

http.AuthToken = "MICROSOFT_GRAPH_ACCESS_TOKEN"

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.StringBuilder")
set sbResponse = Server.CreateObject("Chilkat.StringBuilder")

' Sends:  GET /users/{id | userPrincipalName}/mailFolders
' Note: It is also possible to use the literal string "me" for the current logged-on user.
' For example: GET /me/mailFolders
http.ClearUrlVars 
success = http.SetUrlVar("userPrincipalName","chilkatsoft@outlook.com")
success = http.QuickGetSb("https://graph.microsoft.com/v1.0/users/{$userPrincipalName}/mailFolders",sbResponse)
If ((success <> 1) And (http.LastStatus = 0)) Then
    Response.Write "<pre>" & Server.HTMLEncode( http.LastErrorText) & "</pre>"
    Response.End
End If

' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.JsonObject")
set json = Server.CreateObject("Chilkat.JsonObject")
success = json.LoadSb(sbResponse)
json.EmitCompact = 0

Response.Write "<pre>" & Server.HTMLEncode( "Status code = " & http.LastStatus) & "</pre>"
If (http.LastStatus <> 200) Then
    Response.Write "<pre>" & Server.HTMLEncode( json.Emit()) & "</pre>"
    Response.Write "<pre>" & Server.HTMLEncode( "Failed.") & "</pre>"
End If

Response.Write "<pre>" & Server.HTMLEncode( json.Emit()) & "</pre>"
Response.Write "<pre>" & Server.HTMLEncode( "----") & "</pre>"

' In my test case, this is the result (see below)
' Apparently, this lists folders without listing subfolders (aka child folders)
' There's another REST API call to list child folders.

' To iterate over the folders:
i = 0
numFolders = json.SizeOfArray("value")
Do While i < numFolders
    json.I = i
    Response.Write "<pre>" & Server.HTMLEncode( json.StringOf("value[i].displayName")) & "</pre>"
    i = i + 1
Loop

' The output from the above loop:

' 	Archive
' 	Deleted Items
' 	Drafts
' 	Inbox
' 	Junk Email
' 	Outbox
' 	Sent Items
