Google App Engine上的PHP无法发送邮件

Question

我正在尝试使用此代码在php中发送电子邮件,因为它在文档中给出

require_once 'google/appengine/api/mail/Message.php';

use google\appengine\api\mail\Message;   //line 6 in my code

// ...

$message_body = "...";

$mail_options = [
    "sender" => "admin@example.com",
    "to" => "user@example.com",
    "subject" => "Your example.com account has been activated.",
    "textBody" => $message_body
];

try {
    $message = new Message($mail_options);
    $message->send();
} catch (InvalidArgumentException $e) {
    // ...
}

我收到以下错误

PHP Parse error:  syntax error, unexpected 'use' (T_USE) in /base/data/home/apps/s~myapp-home/mail.371603101929416156/save-email.php on line 6

不知何故,appengine在这条线上投掷错误

use google\appengine\api\mail\Message;

确保您的use语句位于代码文件的顶部,在require_once之后但在任何其他代码之前.
