php - Google 日历 API，类 Google_Service

Question

希望你能帮帮我。

我正在尝试使用 Oauth2 身份验证连接到 Google(日历)API。

为此，我遵循了以下步骤:

• 通过 Google Developers Console 注册应用
• 使用 composer (google-api-php-client) 安装客户端库
• 将脚本放在 vendor 文件夹中:

    require_once 'autoload.php';    require('google/apiclient-services/src/Google/Service/Oauth2.php');    session_start();     // ********************************************************  //    // Get these values from https://console.developers.google.com    // Be sure to enable the Analytics API    // ********************************************************    //    $client_id = 'myclientid';    $client_secret = 'myclientsecret';    $redirect_uri = 'https://domain.nl/dev/vendor/google/apiclient-services/src/Google/Service/Oauth2.php'; //identical as in Google console    $client = new Google_Client();    $client->setApplicationName("Client_Library_Examples");    $client->setClientId($client_id);    $client->setClientSecret($client_secret);    $client->setRedirectUri($redirect_uri);    $client->setAccessType('offline');   // Gets us our refreshtoken    $client->setScopes(array('https://www.googleapis.com/auth/calendar.readonly'));    //For loging out.    if (isset($_GET['logout'])) {         unset($_SESSION['token']);    }    // Step 2: The user accepted your access now you need to exchange it.    if (isset($_GET['code'])) {    $client->authenticate($_GET['code']);      $_SESSION['token'] = $client->getAccessToken();    $redirect = 'https://' . $_SERVER['HTTP_HOST'] . $_SERVER['PHP_SELF'];    header('Location: ' . filter_var($redirect, FILTER_SANITIZE_URL));    }    // Step 1:  The user has not authenticated we give them a link to login        if (!isset($_SESSION['token'])) {    $authUrl = $client->createAuthUrl();    print "Connect Me!";    }        // Step 3: We have access we can now create our service    if (isset($_SESSION['token'])) {    $client->setAccessToken($_SESSION['token']);    print "LogOut
";        $service = new Google_Service_Calendar($client);        $calendarList  = $service->calendarList->listCalendarList();;    while(true) {        foreach ($calendarList->getItems() as $calendarListEntry) {            echo $calendarListEntry->getSummary()."
\n";            // get events             $events = $service->events->listEvents($calendarListEntry->id);            foreach ($events->getItems() as $event) {                echo "-----".$event->getSummary()."
";            }        }        $pageToken = $calendarList->getNextPageToken();        if ($pageToken) {            $optParams = array('pageToken' => $pageToken);            $calendarList = $service->calendarList->listCalendarList($optParams);        } else {            break;        }    }    }

不幸的是，我在单击 Authentication 的“接受”按钮后立即收到错误消息:

Fatal error: Class 'Google_Service' not found in /home/user/domains/domain.nl/private_html/dev/vendor/google/apiclient-services/src/Google/Service/Oauth2.php on line 32

Google research到目前为止没有帮助。

可能的解决方案:

• 正确设置自动加载路径。 检查。

  require_once 'autoload.php';

• 运行受支持的 PHP 版本。 检查(试过 5.6 + 7.1)。

• 检查您在 composer.json 中的库与实际自动加载的库之间是否存在差异。 检查。

感谢您的帮助，谢谢!

更新:此问题已修复。我使用 Oauth2.php 作为我的 redirect_url 而不是返回到我的脚本。初学者错误:)
