PHP 的内置 mail() 函数可以通过 App Engine Mail API 发送电子邮件。这应该适用于大多数现有代码,前提是代码符合发送邮件中列出的限制条件。
或者,您可以直接调用 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';}
