【中文标题】无法解析 [Illuminate\\Mail\\TransportManager] 的 NULL 驱动程序。用于流明框架【英文标题】:Unable to resolve NULL driver for [Illuminate\Mail\TransportManager]. for lumen framework无法解析 [Illuminate\Mail\TransportManager] 的 NULL 驱动程序。用于流明框架 【发布时间】:2020-09-08 19:12:49 【问题描述】:

收到错误 InvalidArgumentException Unable to resolve NULL driver for [Illuminate\Mail\TransportManager] on Lumen using smtp driver。我按照 lumen 文档中设置 Mail 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
MAIL_USERNAME=username@domain.com
MAIL_PASSWORD=password
MAIL_ENCRYPTION=tls
MAIL_FROM_ADDRESS=no-reply@username@domain.com
MAIL_FROM_NAME="Company name"

将 laravel repo 中的 mail.php 添加到 lumen.../config 文件夹中

<?php

return [

    /*

    |
    | This option controls the default mailer that is used to send any email

    |
    */

    'mailers' => [
        'smtp' => [
            'transport' => 'smtp',
            'host' => env('MAIL_HOST', 'smtp.mailgun.org'),
            'port' => env('MAIL_PORT', 587),
            'encryption' => env('MAIL_ENCRYPTION', 'tls'),
            'username' => env('MAIL_USERNAME'),

            'timeout' => null,
            'auth_mode' => null,
        ],

        'ses' => [
            'transport' => 'ses',
        ],

        'mailgun' => [
            'transport' => 'mailgun',

        ],

    ],

    'markdown' => [
        'theme' => 'default',

        'paths' => [
            resource_path('views/vendor/mail'),
        ],
    ],

];

在引导程序中将以下内容添加到我的 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('username2@domain.com.com')->send(new MailableClass('George','Kindly note that your email has been sent'));
    

MailableClass 只是一个扩展 Mailable 以构建视图的类

我还对返回的配置('mail')进行了数据转储

array:4 [▼
  "default" => "smtp"
  "mailers" => array:7 [▼
    "smtp" => array:8 [▼
      "transport" => "smtp"
      "host" => "username@domain.com"
      "port" => "465"
      "encryption" => "tls"
      "username" => "username@domain.com"
      "password" => "password"
      "timeout" => null
      "auth_mode" => null
    ]
    "ses" => array:1 [▶]
    "mailgun" => array:1 [▶]
    "postmark" => array:1 [▶]
    "sendmail" => array:2 [▶]
    "log" => array:2 [▶]
    "array" => array:1 [▶]
  ]
  "from" => array:2 [▶]
  "markdown" => array:2 [▶]

我检查了Illumination/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 将不会返回任何内容,因为它们在mailer 所以我认为它应该是 config['mailer']['host'] ......但这些都是框架文件所以......

我将非常感谢您为解决这个问题提供的帮助。我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

现在可以使用了
