$client = new Google_Client();
$client->setApplicationName("Intakes Calendar");
$client->setClientId('xxxxxxxx.apps.googleusercontent.com');
$client->setClientSecret('xxxxx');
$client->setRedirectUri('xxx');
$client->setDeveloperKey('xxx');
$client->setScopes(array('https://www.googleapis.com/auth/calendar'));
$client->addScope('https://www.googleapis.com/auth/userinfo.email');

if (isset($_GET['code'])) {
    $client->authenticate($_GET['code']);
    $_SESSION['token'] = $client->getAccessToken();
}

if (isset($_SESSION['token'])) {
    //echo "<br>Getting access";
    $client->setAccessToken($_SESSION['token']);
}

if ($client->getAccessToken()){

    if($client->isAccessTokenExpired()) {

        $authUrl = $client->createAuthUrl();
        $button =  '<a class="btn btn-success btn-sm" href="'.$authUrl.'">SIGN IN</a>';
        $msg = '<DIV class="col-md-6 col-md-offset-3 alert alert-warning">You are not signed in with your work email account for remote sessions.' . $button . '</DIV>';

    }else{

        //if logged in check for user email

            $msg = ' <DIV class="col-md-6 col-md-offset-3 alert alert-warning">You are connected and ready for remote sessions.</DIV>';
        else
            $msg = ' <DIV class="col-md-6 col-md-offset-3 alert alert-warning">Please log in with your work email.</DIV>';
    }

}else{

    $authUrl = $client->createAuthUrl();
    $button =  '<a class="btn btn-success btn-sm" href="'.$authUrl.'">SIGN IN</a>';
    $msg = '<DIV class="col-md-6 col-md-offset-3 alert alert-warning">You are not signed in with your work email account for remote sessions.' . $button . '</DIV>';

Answer 1

最后想通了！！！

首先您必须添加gmail的范围

$client->addScope('https://www.googleapis.com/auth/gmail.readonly');

然后启动gmail服务和用户个人资料电子邮件地址

$gmailService = new Google_Service_Gmail($client);
$users = $gmailService->users->getProfile('me');
echo $users['emailAddress']; //this is the logged in user's email address
