(JavaScript) Delete All Files

Permanently deletes all files owned by the user without moving it to the trash.

This example works by first getting a list of all fileIds, and then iterating over the list to delete each file.

See Google Drive Files delete for more information.

Note

This example is intended for running within a Chilkat.Js embedded JavaScript engine. All Chilkat JavaScript examples require Chilkat v11.4.0 or greater.

var success = false;

success = true;

// 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.

var gAuth = new CkAuthGoogle();
gAuth.AccessToken = "GOOGLE-DRIVE-ACCESS-TOKEN";

var rest = new CkRest();

// Connect using TLS.
var bAutoReconnect = true;
success = rest.Connect("www.googleapis.com",443,true,bAutoReconnect);

// Provide the authentication credentials (i.e. the access token)
rest.SetAuthGoogle(gAuth);

// Get 10 results per page for testing.  (The default page size is 100, with a max of 1000.
rest.AddQueryParam("pageSize","10");

var json = new CkJsonObject();
var i;
var numFiles;

// Send the request for the 1st page.
var jsonResponse = rest.FullRequestNoBody("GET","/drive/v3/files");

var pageToken;
var bContinueLoop = rest.LastMethodSuccess && (rest.ResponseStatusCode == 200);

    }

    // Get the next page of files.
    // If the "nextPageToken" is present in the JSON response, then use it in the "pageToken" parameter
    // for the next request.   If no "nextPageToken" was present, then this was the last page of files.
    pageToken = json.StringOf("nextPageToken");
