(Visual FoxPro) OneDrive -- List Non-Root Directory

This gets the collection of DriveItem children for a non-root DriveItem. This is the same as for getting the children for the root DriveItem, except the URL includes the path to the desired non-root DriveItem.

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.

loHttp = CreateObject('Chilkat_9_5_0.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 FilesRead or Files.ReadWrite scope.)
loHttp.AuthToken = "MICROSOFT_GRAPH_ACCESS_TOKEN"

* Send a Get request like this:
* GET /me/drive/root:/{item-path}:/children

* This example will get the DriveItems in /Misc/old
* (In other words, we're getting the directory listing for /Misc/old.)
loHttp.SetUrlVar("item_path","/Misc/old")

* The response should be JSON.
loJson = CreateObject('Chilkat_9_5_0.JsonObject')

loJson.Load(lcResp)

* A successful response should return a status code of 200.
