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

* This example uses a previously obtained access token having permission for the 
* Google Drive scope.

loGAuth = CreateObject('Chilkat.AuthGoogle')
loGAuth.AccessToken = "GOOGLE-DRIVE-ACCESS-TOKEN"

loRest = CreateObject('Chilkat.Rest')

* Connect using TLS.
lnBAutoReconnect = 1
lnSuccess = loRest.Connect("www.googleapis.com",443,1,lnBAutoReconnect)

* Provide the authentication credentials (i.e. the access token)
loRest.SetAuthGoogle(loGAuth)

* -------------------------------------------------------------------------
* A multipart upload to Google Drive needs a multipart/related Content-Type
loRest.AddHeader("Content-Type","multipart/related")

* Specify each part of the request.

* The 1st part is JSON with information about the file.
loRest.PartSelector = "1"
loRest.AddHeader("Content-Type","application/json; charset=UTF-8")

loJson = CreateObject('Chilkat.JsonObject')
loJson.AppendString("name","testHello.txt")
loJson.AppendString("description","A simple file that says Hello World.")
loJson.AppendString("mimeType","text/plain")

* To place the file in a folder, we must add a parents[] array to the JSON
* and list the folder id's.  It's possible for a file to be in multiple folders at once
* if it has more than one parent.  If no parents are specified, then the file is created
* in the My Drive folder.  
* Note: We'll assume we already have the id if the folder.  It is the id's that are specified here,
* not the folder names.

lcFolderId = "0B53Q6OSTWYolY2tPU1BnYW02T2c"

loRest.SetMultipartBodyString(loJson.Emit())

* The 2nd part is the file content, which will contain "Hello World!"

loRest.SetMultipartBodyString(lcFileContents)

* A successful response looks like this:

*   "id": "0B53Q6OSTWYoldmJ0Z3ZqT2x5MFk",
*   "name": "Untitled",
*   "mimeType": "text/plain"

* Get the fileId:
