php - 将 Google 日历 API 集成到 WordPress 插件中

问题描述

我有一个与我的 WordPress 配合使用的日历插件，我想集成 Google 日历 API 来创建、读取、更新、删除 Google 日历事件。这是我遵循的过程。

我在不同的日历插件类中创建了一个函数，我从谷歌日历 API 文档（https://developers.google.com/calendar/quickstart/php）获得：

function getClient() {
        try{
            $client = new Google_Client();
            $client->setApplicationName('Google Calendar API');
            $client->setScopes(Google_Service_Calendar::CALENDAR);
            $client->setAuthConfig(AEC_PATH .'credentials.json');
            $client->setAccessType('offline');
            $client->setPrompt('select_account consent');

            // Load previously authorized token from a file, if it exists.
            // The file token.json stores the user's access and refresh tokens, and is
            // created automatically when the authorization flow completes for the first
            // time.
            $tokenPath = 'token.json';
            if (file_exists($tokenPath)) {
                $accessToken = json_decode(file_get_contents($tokenPath), true);
                $client->setAccessToken($accessToken);
            } else {
                print 'Access Token not generated!!';
            }

            // If there is no previous token or it's expired.
            if ($client->isAccessTokenExpired()) {
                // Refresh the token if possible, else fetch a new one.
                if ($client->getRefreshToken()) {
                    $client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
                } else {
                    // Request authorization from the user.
                    $authUrl = $client->createAuthUrl();
                    printf("Open the following link in your browser:\n%s\n", $authUrl);
                    print 'Enter verification code: ';
                    $authCode = trim(fgets(STDIN));

                    // Exchange authorization code for an access token.
                    $accessToken = $client->fetchAccessTokenWithAuthCode($authCode);
                    $client->setAccessToken($accessToken);

                    // Check to see if there was an error.
                    if (array_key_exists('error', $accessToken)) {
                        throw new Exception(join(', ', $accessToken));
                    }
                }
                // Save the token to a file.
                if (!file_exists(dirname($tokenPath))) {
                    mkdir(dirname($tokenPath), 0700, true);
                }
                file_put_contents($tokenPath, json_encode($client->getAccessToken()));
            }

            return $client;
        } catch(Exception $e) {
            print_r($e->getMessage());
        }

现在我在构造函数中添加了一个动作钩子来初始化这个函数。

add_action('init', array($this, 'getClient'));

现在我在另一个函数中调用这个函数 getClient() 以在特定时间间隔调用。

try{
            // Get the API client and construct the service object.
            $client = $this->getClient();
            $service = new Google_Service_Calendar($client);
            $calendarId = '<Google_Calendar_ID>';

            $event = new Google_Service_Calendar_Event(array(
                'summary' => $input->title,
                'location' => $input->address.''.$input->city.''.$input->state.''.$input->country.''.$input->zip,
                'description' => $input->description,
                'start' => array(
                    'dateTime' => '2019-09-22T09:00:00-07:00'
                ),
                'end' => array(
                    'dateTime' => '2019-09-22T17:00:00-07:00'
                ),
                'reminders' => array(
                    'useDefault' => FALSE,
                    'overrides' => array(
                    array('method' => 'email', 'minutes' => 24 * 60),
                    array('method' => 'popup', 'minutes' => 10),
                    ),
                ),
            ));

            $event = $service->events->insert($calendarId, $event);
            echo "--Google Event Created-->";
            print_r($event);
        } catch(Exception $e) {
            print_r($e->getMessage());
        }

我收到授权错误，而不是为我的 Google 日历创建新活动。

{
 "error": {
  "errors": [
   {
    "domain": "global",
    "reason": "insufficientPermissions",
    "message": "Insufficient Permission: Request had insufficient authentication scopes."
   }
  ],
  "code": 403,
  "message": "Insufficient Permission: Request had insufficient authentication scopes."
 }

您能否帮助我理解为什么会出现此错误以及如何解决？
