(Visual FoxPro) Create Folder

In the Drive API, a folder is essentially a file — one identified by the special folder MIME type application/vnd.google-apps.folder

See Google Drive Files: create for more details.

Also See Working with Folders for more details.

* Creating a folder is technically an upload of a 0-length file
* having a MIME type of "application/vnd.google-apps.folder"

lnSuccess = 1

* It 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.

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.AuthGoogle')
loGAuth = CreateObject('Chilkat.AuthGoogle')
loGAuth.AccessToken = "GOOGLE-DRIVE-ACCESS-TOKEN"

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.Rest')
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 folder.
loRest.PartSelector = "1"
loRest.AddHeader("Content-Type","application/json; charset=UTF-8")

* For versions of Chilkat < 10.0.0, use CreateObject('Chilkat_9_5_0.JsonObject')
loJson = CreateObject('Chilkat.JsonObject')
loJson.AppendString("name","testFolder")
loJson.AppendString("description","A folder to contain test files.")
loJson.AppendString("mimeType","application/vnd.google-apps.folder")
loRest.SetMultipartBodyString(loJson.Emit())

* The 2nd part would be the file content.
* Since this is a folder, skip the 2nd part entirely and go straight to the upload..

* A successful response looks like this:
* {

*   "name": "testFolder",
*   "mimeType": "application/vnd.google-apps.folder"
* }

* Get the fileId:
? "fileId: " + loJson.StringOf("id")
