创建未登录的Google日历帐户

Question

I'm trying to create a Google calendar event when a page is refreshed. Here's my code:

<?php
require_once '../../src/config.php';

session_start();

$client = new Google_Client();
$client->setApplicationName("Google Calendar PHP Starter Application");

// Visit https://code.google.com/apis/console?api=calendar to generate your
//client id, client secret, and to register your redirect uri.
$client->setClientId('--the client id--');
$client->setClientSecret('--the client secret--');
$client->setRedirectUri('http://acromediainc.acrobuild.com/calendar/google-api-php-client/examples/calendar/simple.php');
//$client->setDeveloperKey('--the developer key--');
$cal = new Google_CalendarService($client);



if (isset($_GET['logout'])) {
  unset($_SESSION['token']);
}

if (isset($_GET['code'])) {
$client->authenticate($_GET['code']);
$_SESSION['token'] = $client->getAccessToken();
header('Location: http://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF']);
}

if (isset($_SESSION['token'])) {
$client->setAccessToken($_SESSION['token']);
}

if ($client->getAccessToken()) {
$calList = $cal->calendarList->listCalendarList();
print "<h1>Calendar List</h1><pre>" . print_r($calList, true) . "</pre>";


$_SESSION['token'] = $client->getAccessToken();

$event = new Google_Event();
$event->setSummary('Halloween');
$event->setLocation('The Neighbourhood');
$start = new Google_EventDateTime();
$start->setTimeZone('America/Los_Angeles');
$start->setDateTime('2014-4-30T10:00:00.000');
$event->setStart($start);
$end = new Google_EventDateTime();
$end->setTimeZone('America/Los_Angeles');
$end->setDateTime('2014-4-30T10:20:00.000');
$event->setEnd($end);
$createdEvent = $cal->events->insert('mycalendarid@group.calendar.google.com', $event);
} else {
$authUrl = $client->createAuthUrl();
print "<a class='login' href='$authUrl'>Connect Me!</a>";
}

...and here's the config file:

  'urlshortener' => array('scope' => 'https://www.googleapis.com/auth/urlshortener')
)
);

I've got the OAuth stuff commented out because I want to use the developer key instead. Right now, my code works fine if I'm logged into my browser on the account the calendar is associated with, but if I'm logged on with another gmail account, I get an error: 'Error calling POST https://www.googleapis.com/calendar/v3/calendars/2pnfetf7qtph9i7sq9tcfep1jk@group.calendar.google.com/events : (404) Not Found' Which is basically saying it can't find the calendar with that ID. If I try to run this code in a browser that is not logged in, the 'else' clause runs and asks the user to log in. Is there a way to create a calendar event without being logged in to a gmail account associated with that calendar event? Thanks.

Answer 1

First you need to store Refesh token for future use. You can get it by

$client->setAccessType('offline'); 

in this you will get access token along with refresh token. Please store refresh token into db.

And then write down code before you perform action as given below:

//Code start here to get access token

if($client->isAccessTokenExpired()) {

    echo 'Access Token Expired'; // Debug
    $client->refreshToken("Stored Refesh Token"); //Stored Refesh Token is what we save for first req
    $_SESSION['access_token']=$client->getAccessToken();
    $client->setAccessToken($_SESSION['access_token']);
}

If you use this then you need to login again to add/edit/delete or any other google calendar method which required authorization.
