php - 无法解析 [Illuminate\Mail\TransportManager] 的 NULL 驱动程序。用于流明框架

Question

收到错误 InvalidArgumentException 无法使用 smtp 驱动程序在 Lumen 上解析 [Illuminate\Mail\TransportManager] 的 NULL 驱动程序。我按照lumen文档中设置邮件的所有步骤进行操作。这是我的环境

MAIL_DRIVER=smtp
MAIL_HOST=domain.com
MAIL_PORT=465
<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="571a161e1b080204120519161a126a2224322539363a321733383a363e397934383a" rel="noreferrer noopener nofollow">[email protected]</a>
MAIL_PASSWORD=password
MAIL_ENCRYPTION=tls
MAIL_FROM_ADDRESS=no-reply@<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="add8dec8dfc3ccc0c8edc9c2c0ccc4c383cec2c0" rel="noreferrer noopener nofollow">[email protected]</a>
MAIL_FROM_NAME="Company name"

将 laravel 存储库中的 mail.php 添加到 lumen.../config 文件夹

<?php

        'paths' => [

];

将以下内容添加到 bootstrap 中的 app.php

$app->register(Illuminate\Mail\MailServiceProvider::class);
$app->configure('mail');
$app->configure('services');
$app->alias('mailer', Illuminate\Mail\Mailer::class);
$app->alias('mailer', Illuminate\Contracts\Mail\Mailer::class);
$app->alias('mailer', Illuminate\Contracts\Mail\MailQueue::class);

发送邮件的实现

public function testMail()
    {
        Mail::to('<a href="https://stackoverflow.com/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="bdc8ced8cfd3dcd0d88ffdd9d2d0dcd4d393ded2d093ded2d0" rel="noreferrer noopener nofollow">[email protected]</a>')->send(new MailableClass('George','Kindly note that your email has been sent'));
    }

MailableClass 只是一个扩展 Mailable 来构建 View 的类

我还对返回此的配置('mail')进行了数据转储

array:4 [▼
  "default" => "smtp"
  "mailers" => array:7 [▼
    "smtp" => array:8 [▼
      "transport" => "smtp"

我检查了Illumina/mail中的Manager.php和TransportManager.php文件当我将驱动程序函数的驱动程序值设置为“smtp”时，我能够传递给 TransportManager.php 的 createSmtpDriver() 。您可以在此处查看相应的代码...

    /**
     * Get a driver instance.
     *
     * @param  string  $driver
     * @return mixed
     *
     * @throws \InvalidArgumentException
     */
    public function driver($driver = "smtp") //originally $driver = null
    {
        $driver = $driver ?: $this->getDefaultDriver();

        if (is_null($driver)) {
            throw new InvalidArgumentException(sprintf(
                'Unable to resolve NULL driver for [%s].', static::class
            ));
        }

        // If the given driver has not been created before, we will create the instances
        // here and cache it so we can return it next time very quickly. If there is
        // already a driver created by this name, we'll just return that instance.
        if (! isset($this->drivers[$driver])) {
            $this->drivers[$driver] = $this->createDriver($driver);
        }

        return $this->drivers[$driver];
    }

我在createSmtpDriver()中做了一个dd

       protected function createSmtpDriver()
    {
        $config = $this->app->make('config')->get('mail');
        **dd($config);**

        // The Swift SMTP transport instance will allow us to use any SMTP backend
        // for delivering mail such as Sendgrid, Amazon SES, or a custom server
        // a developer has available. We will just pass this configured host.
        $transport = new SmtpTransport($config['host'], $config['port']);

        if (isset($config['encryption'])) {
            $transport->setEncryption($config['encryption']);
        }

        // Once we have the transport we will check for the presence of a username
        // and password. If we have it we will set the credentials on the Swift
        // transporter instance so that we'll properly authenticate delivery.
        if (isset($config['username'])) {
            $transport->setUsername($config['username']);

            $transport->setPassword($config['password']);
        }

        // Next we will set any stream context options specified for the transport
        // and then return it. The option is not required any may not be inside
        // the configuration array at all so we'll verify that before adding.
        if (isset($config['stream'])) {
            $transport->setStreamOptions($config['stream']);
        }

        return $transport;
    }

这个 dd 的结果基本上是上面 config('mail') 中的结果，从中我们可以看到 config['host'], config['port'] ..etc 不会返回任何内容，因为它们位于mailer 所以我认为它应该是 config['mailer']['host'] 相反...但这些都是框架文件所以...

我非常感谢您提供的帮助来解决这个问题。完全不知道我做错了什么。谢谢

哦对了忘了我也安装了..

composer require guzzlehttp/guzzle

谢谢
