// 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];
BOOL 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",

//     "type": "eventResponse",

//  },

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