(JavaScript) Google Calendar Search Events (List Events with Optional Query Parameters)

See more Google Calendar Examples

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;

// 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..
var jsonToken = new CkJsonObject();
success = jsonToken.LoadFile("qa_data/tokens/googleCalendar.json");
if (jsonToken.HasMember("access_token") == false) {
    console.log("No access token found.");
    return;
}

var http = new CkHttp();
http.AuthToken = jsonToken.StringOf("access_token");

// We'll want to build a URL with the query params..
var sbUrl = new CkStringBuilder();
sbUrl.Append("https://www.googleapis.com/calendar/v3/calendars/{$calendarId}/events?");

// Use the HTTP request object as a helper for creating the URL encoded query param list..
var req = new CkHttpRequest();

// Find events with the word "pizza".
req.AddParam("q","pizza");

// Get events for the current date/time or later.
var dt = new CkDateTime();
dt.SetFromCurrentSystemTime();
req.AddParam("timeMin",dt.GetAsTimestamp(false));

// Add these query params to the URL:
sbUrl.Append(req.GetUrlEncodedParams());

// Examine the URL..
console.log("URL: " + sbUrl.GetAsString());

// The URL looks like this:
// https://www.googleapis.com/calendar/v3/calendars/{$calendarId}/events?q=pizza&timeMin=2017-08-11T13%3A35%3A28Z

// Let's get events in the primary calendar.  A calendar ID could have be used instead of "primary".
http.SetUrlVar("calendarId","primary");
var sbResponse = new CkStringBuilder();
success = http.QuickGetSb(sbUrl.GetAsString(),sbResponse);
if (success !== true) {
    console.log(http.LastErrorText);
    return;
}

if (http.LastStatus !== 200) {
    // Note: If a 401 unauthorized response is received, it likely means that the OAuth2 access token needs
    // to be refreshed or re-fetched.
    console.log("Error response status: " + http.LastStatus);
    console.log(sbResponse.GetAsString());
    return;
}

console.log(sbResponse.GetAsString());
