使用 Laravel 进行动态邮件配置答案

【问题描述】：

在我的 Laravel 应用程序中，我尝试根据登录用户的 company_id 发送邮件通知：

我有这个：

$mail=DB::table('mail_settings')->first();
$config = array(
           'driver' => $mail->driver,
           'host' => $mail->host,
           'port' => $mail->port,
           'from' => array('address' => $mail->from_address, 'name' => $mail->from_name),
           'encryption' => $mail->encryption,
           'username' => $mail->username,
           'password' => $mail->password,
           'sendmail' => '/usr/sbin/sendmail -bs',
           'pretend' => false
       );
Config::set('mail',$config);

型号

class Company extends Model
{
   protected $table = 'companies';
   protected $fillable = [
    'id',
    'organization_name'
  ];
}

class User extends Authenticatable
{
   protected $fillable = [
    'name',
    'company_id',
    'email',
 ];
}

有没有办法在创建邮件传输之前即时覆盖默认邮件配置（在 app/config/mail.php 中）（例如，配置存储在数据库中）？

谢谢

有没有办法重新创建 laravel swiftmailer 传输，以便它可以获取更新的配置值？

Mailer 类是在Illuminate\Mail\MailManager 类的resolve() 方法中创建的。如果你想动态创建一个邮件程序，你需要在你的控制器中调整这个函数来使用你的$config数组并返回一个Mailer，你可以从中链接常用的方法。

protected function resolve($name)
{
    $config = $this->getConfig($name);

    if (is_null($config)) {
        throw new InvalidArgumentException("Mailer [{$name}] is not defined.");
    }

    // Once we have created the mailer instance we will set a container instance
    // on the mailer. This allows us to resolve mailer classes via containers
    // for maximum testability on said classes instead of passing Closures.
    $mailer = new Mailer(
        $name,
        $this->app['view'],
        $this->createSwiftMailer($config),
        $this->app['events']
    );

    if ($this->app->bound('queue')) {
        $mailer->setQueue($this->app['queue']);
    }

    // Next we will set all of the global addresses on this mailer, which allows
    // for easy unification of all "from" addresses as well as easy debugging
    // of sent messages since these will be sent to a single email address.
    foreach (['from', 'reply_to', 'to', 'return_path'] as $type) {
        $this->setGlobalAddress($mailer, $config, $type);
    }

    return $mailer;
}
