* 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"

* Sends the following GET request:

* Search the entire drive like this:
* If not using "me", then the path should be /v1.0/users/{id | userPrincipalName}/...
* GET /v1.0/me/drive/root/search(q='{search-text}')

* Or search under a particular folder like this:
* GET /v1.0/me/drive/root:/{item-path}:/search(q='{search-text}')

* This example will search for files in or under the "/Misc" directory, having "penguin" in the file path.
loHttp.SetUrlVar("item_path","/Misc")
loHttp.SetUrlVar("search_text","penguins")

* The response should be JSON.
