如何使用服务器修改谷歌日历API上的事件

Question

我让oauth2工作 - 当用户登录我的应用程序时，他们必须登录他们的Google帐户。然后，他们可以手动将我网站日历中的所有事件同步到他们的Google日历。

但是，我怎样才能让我的服务器能够修改他们的 Google 日历(添加、编辑、删除(事件，而它们实际上并不出现在计算机上？因为现在，它使用$_SESSION来检查用户是否已登录到他们的Google帐户。

例如，以下是通过API将事件插入/添加到Google日历的方法：

$client = new Google_Client();
$client->setAuthConfig('client_secrets.json');
$client->addScope(Google_Service_Calendar::CALENDAR);
$client->setAccessType("offline");
$service = new Google_Service_Calendar($client);
if (isset($_SESSION['access_token']) && $_SESSION['access_token']) {
$event = new Google_Service_Calendar_Event(array(
'summary' => 'Google I/O 2015',
'location' => '800 Howard St., San Francisco, CA 94103',
'description' => 'A chance to hear more about Google's developer products.',
'start' => array(
'dateTime' => '2015-05-28T09:00:00-07:00',
'timeZone' => 'America/Los_Angeles',
),
'end' => array(
'dateTime' => '2015-05-28T17:00:00-07:00',
'timeZone' => 'America/Los_Angeles',
),
));
$event = $service->events->insert('primary', $event);
} else {
$redirect_uri = '/oauth.php';
header('Location: ' . filter_var($redirect_uri, FILTER_SANITIZE_URL));
exit();
}

但如您所见，这需要一个存储在$_SESSION中access_token ，如果没有访问令牌，那么它将重定向他们登录到他们的 Google 帐户。

我的服务器如何在后台访问其 Google 日历帐户并添加/修改/移除活动？

Answer 1

您必须在 console.developers.google.com 中创建"应用程序"并为其创建"授权凭据"。 您将获得一个需要用于身份验证的 json 文件

阅读此处了解更多详情 https://developers.google.com/api-client-library/php/auth/web-app#creatingcred

您可以使用此 https://github.com/googleapis/google-api-php-client

所以编辑看起来像

include_once 'google.api.php';
$eventId = '010101010101010101010101'; 
$calendarID='[e-mail]';
// Get Event for edit 
$event = $service->events->get($calendarID, $eventId);    
$event->setSummary('New title');
$event->setDescription('New describtion');
$event->setStart(
new Google_Service_Calendar_EventDateTime(['dateTime' => date("c", strtotime("2018-09-20 09:40:00")),'timeZone' => 'Europe/Moscow'])
);
$event->setEnd(
new Google_Service_Calendar_EventDateTime(['dateTime' => date("c", strtotime("2018-09-20 10:40:00")),'timeZone' => 'Europe/Moscow'])
);
$updatedEvent = $service->events->update($calendarID, $eventId, $event);

google.api.php 将是这样的

require_once __DIR__ .'/vendor/autoload.php';
function getClient()
{
$client = new Google_Client();
$client->setApplicationName('Google Calendar API PHP Quickstart');
$client->setScopes(Google_Service_Calendar::CALENDAR);
$client->setAuthConfig('credentials.json');
$client->setAccessType('offline');
// Load previously authorized credentials from a file.
$credentialsPath = 'token.json';
if (file_exists($credentialsPath)) {
$accessToken = json_decode(file_get_contents($credentialsPath), true);
} else {
// Request authorization from the user.
$authUrl = $client->createAuthUrl();
printf("Open the following link in your browser:n%sn", $authUrl);
print 'Enter verification code: ';
$authCode = trim(fgets(STDIN));
// Exchange authorization code for an access token.
$accessToken = $client->fetchAccessTokenWithAuthCode($authCode);
// Store the credentials to disk.
if (!file_exists(dirname($credentialsPath))) {
mkdir(dirname($credentialsPath), 0700, true);
}
file_put_contents($credentialsPath, json_encode($accessToken));
printf("Credentials saved to %sn", $credentialsPath);
}
$client->setAccessToken($accessToken);
// Refresh the token if it's expired.
if ($client->isAccessTokenExpired()) {
$client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
file_put_contents($credentialsPath, json_encode($client->getAccessToken()));
}
return $client;
}

// Get the API client and construct the service object.
$client = getClient();
$service = new Google_Service_Calendar($client);
// Print the next 10 events on the user's calendar.
$calendarId = 'primary';
$optParams = array(
'maxResults' => 10,
'orderBy' => 'startTime',
'singleEvents' => true,
'timeMin' => date('c'),
);
$results = $service->events->listEvents($calendarId, $optParams);
if (empty($results->getItems())) {
print "No upcoming events found.n";
} else {
print "Upcoming events:n";
foreach ($results->getItems() as $event) {
$start = $event->start->dateTime;
if (empty($start)) {
$start = $event->start->date;
}
printf("%s (%s)n", $event->getSummary(), $start);
}
}
