//  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 Calendar scope.

//  In this example, Get Google Calendar OAuth2 Access Token, the access
//  token was saved to a JSON file.  This example fetches the access token from the file..
CkoJsonObject *jsonToken = [[CkoJsonObject alloc] init];
success = [jsonToken LoadFile: @"qa_data/tokens/googleCalendar.json"];
if ([jsonToken HasMember: @"access_token"] == NO) {
    NSLog(@"%@",@"No access token found.");
    return;
}

CkoHttp *http = [[CkoHttp alloc] init];
http.AuthToken = [jsonToken StringOf: @"access_token"];

//  Let's get the primary calendar.
NSString *jsonResponse = [http QuickGetStr: @"https://www.googleapis.com/calendar/v3/users/me/calendarList/primary"];
if (http.LastMethodSuccess != YES) {
    NSLog(@"%@",http.LastErrorText);
    return;
}

NSLog(@"%@",jsonResponse);

//  A sample response is:

//  {
//   "kind": "calendar#calendarListEntry",
//   "etag": "\"1465249947472000\"",
//   "id": "support@chilkatcloud.com",
//   "summary": "support@chilkatcloud.com",
//   "timeZone": "America/Chicago",
//   "colorId": "14",
//   "backgroundColor": "#9fe1e7",
//   "foregroundColor": "#000000",
//   "selected": true,
//   "accessRole": "owner",
//   "defaultReminders": [
//    {
//     "method": "popup",
//     "minutes": 10

//   ],
//   "notificationSettings": {
//    "notifications": [
//     {
//      "type": "eventCreation",

//      "method": "email"
//     }

//   },
//   "primary": true

//  It can be parsed like this:
CkoJsonObject *json = [[CkoJsonObject alloc] init];
[json Load: jsonResponse];

NSLog(@"%@%@",@"kind: ",[json StringOf: @"kind"]);
NSLog(@"%@%@",@"id: ",[json StringOf: @"id"]);
