Question

我已将Google Calendar API放在包装类中

Class cl_calendar
{
private $db;
private $google_client;
private $google_service;
private $calendar_id;

public function __construct($calendar_id = 'primary')
{   $this->db = new cl_database();

    // ...

    $this->do_initialise();
}

public function do_initialise()
{   require_once '../plugins/google-api-php-client-2.2.1/vendor/autoload.php';

    $this->google_client = $this->getClient();
    $this->google_service = new Google_Service_Calendar($this->google_client);
}

private function getClient()
{   $client = new Google_Client();
    $client->setApplicationName('Google Calendar API PHP');
    $client->setScopes(Google_Service_Calendar::CALENDAR);
    $client->setAuthConfig('../plugins/google-api-php-client-2.2.1/client_secret.json');
    $client->setAccessType('offline');

    $credentialsPath = $this->expandHomeDirectory('../plugins/google-api-php-client-2.2.1/credentials.json');
    if (file_exists($credentialsPath)) {
        $accessToken = json_decode(file_get_contents($credentialsPath), true);
    } else {
        $authUrl = $client->createAuthUrl();
        printf("Open the following link in your browser:\n%s\n", $authUrl);
        print 'Enter verification code: ';
        $authCode = trim('...');

        $accessToken = $client->fetchAccessTokenWithAuthCode($authCode);

        if (!file_exists(dirname($credentialsPath))) {
            mkdir(dirname($credentialsPath), 0700, true);
        }
        file_put_contents($credentialsPath, json_encode($accessToken));
        printf("Credentials saved to %s\n", $credentialsPath);
    }
    $client->setAccessToken($accessToken);

    if ($client->isAccessTokenExpired()) {
        $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
        file_put_contents($credentialsPath, json_encode($client->getAccessToken()));
    }
    return $client;
}

private function expandHomeDirectory($path)
{   $homeDirectory = getenv('HOME');
    if (empty($homeDirectory)) {
        $homeDirectory = getenv('HOMEDRIVE') . getenv('HOMEPATH');
    }
    return str_replace('~', realpath($homeDirectory), $path);
}

public function do_cleanup_deleted_events() {
    $qry = 'select ...';
    $sql = $this->db->do_select($qry);

    foreach ($sql as $row) {
        $event = $this->google_service->events->get($this->calendar_id, $row['calendar_id']);

        if ($event) {
            if ($event['status'] == 'cancelled') {   // DELETED
                $qry = 'update ...';
                $this->db->do_update($qry);
            }
        }
    }

    echo 'ok';

    return true;
}
}

到目前为止，一切都很好。这段代码可以完美地工作（省去了一些不必要的Google API代码和密钥。

但是...当我删除“ echo'ok'”时，浏览器返回“此页面不起作用”； do_cleanup_deleted_events（）方法中的一行。可能很明显，但我不明白为什么会这样。

我创建类并运行方法的代码：

require_once('../logic/calendar.class.php');
$calendar = new cl_calendar('primary');
$calendar->do_cleanup_deleted_events();

Answer 1

找到了。好吧。

所以我要查找的事件不再存在于该日历中。因此，错误。当我将代码放在try catch中时，它可以解决问题。

但是，删除try catch并放入“ echo'ok'”；也可以“解决”问题。我发现奇怪的是，放置回声后错误不会持续存在。不知道为什么会这样。

PHP类返回“此页面无法正常工作”而不回显
