使PHP的mail（）异步 [英] Making PHP's mail() asynchronous

问题描述

我有PHP的 mail（）使用 ssmtp ，它不没有队列/线轴，与AWS SES同步。

I have PHP's mail() using ssmtp which doesn't have a queue/spool, and is synchronous with AWS SES.

我听说可以使用 SwiftMail 提供了一个线轴，但是我无法使用简单的配方来使用它，就像我目前使用 mail（）一样。

I heard I could use SwiftMail to provide a spool, but I couldn't work out a simple recipe to use it like I do currently with mail().

我希望最少的代码提供异步邮件。我不在乎电子邮件是否发送失败，但是有一个日志是很好的。

I want the least amount of code to provide asynchronous mail. I don't care if the email fails to send, but it would be nice to have a log.

任何简单的提示或技巧？缺少运行完整的邮件服务器？我正在想一个 sendmail 包装器可能是答案，但我无法解决 nohup 。

Any simple tips or tricks? Short of running a full blown mail server? I was thinking a sendmail wrapper might be the answer but I couldn't work out nohup.

推荐答案

php-fpm

您必须运行php-fpm fastcgi_finish_request 可供使用。

echo "I get output instantly";
fastcgi_finish_request(); // Close and flush the connection.
sleep(10); // For illustrative purposes. Delete me.
mail("[e-mail]", "lol", "Hi");

在完成向用户的请求后，排队任意任意代码进行处理非常简单：

It's pretty easy queuing up any arbitrary code to processed after finishing the request to the user:

$post_processing = [];
/* your code */
$email = "[e-mail]";
$subject = "lol";
$message = "Hi";

$post_processing[] = function() use ($email, $subject, $message) {
  mail($email, $subject, $message);
};

echo "Stuff is going to happen.";

/* end */

fastcgi_finish_request();

foreach($post_processing as $function) {
  $function();
}

Hipster background worker

立即超时卷曲，让新的请求处理。我在共享的主机之前这样做是很酷的。

Hipster background worker

Instantly time-out a curl and let the new request deal with it. I was doing this on shared hosts before it was cool. (it's never cool)

if(!empty($_POST)) {
  sleep(10);
  mail($_POST['email'], $_POST['subject'], $_POST['message']);
  exit(); // Stop so we don't self DDOS.
}

$ch = curl_init("http://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI']);

curl_setopt($ch, CURLOPT_TIMEOUT, 1);
curl_setopt($ch, CURLOPT_NOSIGNAL, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, [
  'email' => '[e-mail]',
  'subject' => 'foo',
  'message' => 'bar'
]);

curl_exec($ch);
curl_close($ch);

echo "Expect an email in 10 seconds.";
