PHP 內建的 mail() 函式可透過 App Engine Mail API 傳送電子郵件。只要符合「傳送郵件」一節所列的限制,這項功能應可與大多數現有程式碼搭配使用。
或者,您也可以直接呼叫 Mail API:
use google\appengine\api\mail\Message;// Notice that $image_content_id is the optional Content-ID header value of the// attachment. Must be enclosed by angle brackets (<>)$image_content_id = '<image-content-id>';// Pull in the raw file data of the image file to attach it to the message.$image_data = file_get_contents('image.jpg');try { $message = new Message(); $message->setSender('from@example.com'); $message->addTo('to@example.com'); $message->setSubject('Example email'); $message->setTextBody('Hello, world!'); $message->addAttachment('image.jpg', $image_data, $image_content_id); $message->send(); echo 'Mail Sent';} catch (InvalidArgumentException $e) { echo 'There was an error';}
