在Lumen发送邮件

Question

I've read a lot of guides and questions and answers on how to send mail using Lumen. I've tried a lot of these suggestions.

However, I still get this error:

(1/1) FatalThrowableError
Type error: Too few arguments to function Illuminate\Support\Manager::createDriver(), 0 passed in /var/www/monitor/vendor/illuminate/support/Manager.php on line 88 and exactly 1 expected

Full stack trace here.

This is my controller:

use Illuminate\Support\Facades\Mail;

public function check() {
    $response = $this->getResponse();
    if ($response) {
        if ($this->isAlive($response->state)) {
            $user = new \stdClass();
            $user->email = '****@gmail.com';
            $user->name = 'Albert';
            Mail::raw('test', function($mail) use ($user) {
                $mail->to($user->email, $user->name)->subject('Test Subject');
            });
            // I've also tried Mail::send() but no luck
            echo 'System is fine';
        } else {
            echo 'System has issues';
        }
    } else {
        echo 'Error connecting';
    }
}

I have uncommented and added the following lines to my bootstrap/app.php:

$app->withFacades();
$app->register(App\Providers\AppServiceProvider::class);
$app->register(Illuminate\Mail\MailServiceProvider::class);

I've got the following in my .env file:

MAIL_DRIVER=smtp
MAIL_HOST=smtp.gmail.com
MAIL_PORT=587
MAIL_USERNAME=[e-mail]
MAIL_PASSWORD=mygmailpassword
MAIL_ENCRYPTION=tls

Am I missing something?

The problem is that the mail manager depends on the mail configuration, and Lumen has not included the mail configuration by default since 5.1. If you are using Lumen > 5.1, you will need to add your own mail config file, and update your bootstrap file to load the configuration file.

First, create a config directory next to your app directory.

Next, add a mail.php file in your new config directory. You can copy the contents from the default Laravel install that matches the Lumen version you are using (for example, if you're using Lumen 5.4, just copy the mail.php config file from Laravel 5.4).

Finally, in your bootstrap/app.php file, load the configuration file:

$app->configure('mail');

I would put this line before you register your mail service provider, just to be safe.
