Get a Google Calendar

See more Google Calendar Examples

Demonstrates how to get a particular Google Calendar. The calendar can be referenced by the calendar ID, or by the keyword "primary". Rust

// 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..
let json_token = chilkat::JsonObject::new();
let _ = json_token.load_file("qa_data/tokens/googleCalendar.json").is_ok();
if !json_token.has_member("access_token") {
    println!("No access token found.");
    return;
}

let http = chilkat::Http::new();
http.set_auth_token(&json_token.string_of("access_token").unwrap_or_default());

// Let's get the primary calendar.
let Ok(json_response) = http.quick_get_str("https://www.googleapis.com/calendar/v3/users/me/calendarList/primary") else {
    println!("{}", http.last_error_text());
    return;
};

println!("{}", json_response);

// 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"
//    },
//    {
//     "type": "eventChange",
//     "method": "email"
//    },
//    {
//     "type": "eventCancellation",
//     "method": "email"
//    },
//    {
//     "type": "eventResponse",
//     "method": "email"
//    }
//   ]
//  },
//  "primary": true
// }

// It can be parsed like this:
let json = chilkat::JsonObject::new();
let _ = json.load(&json_response);

println!("kind: {}", json.string_of("kind").unwrap_or_default());
println!("id: {}", json.string_of("id").unwrap_or_default());

// Examine the notification settings, if any..
let num_settings = json.size_of_array("notificationSettings.notifications");
if num_settings > 0 {
    let mut i = 0;
    while i < num_settings {
        json.set_i(i);
        println!("Notification Type: {}", json.string_of("notificationSettings.notifications[i].type").unwrap_or_default());
        println!("Notification Method: {}", json.string_of("notificationSettings.notifications[i].method").unwrap_or_default());
        i = i + 1;
    }
