使用数据库中的值进行动态邮件配置[Laravel]

Question

我在Laravel应用程序中创建了一个服务提供程序SettingsServiceProvider.这会缓存数据库中的设置表.

$settings = $cache->remember('settings', 60, function() use ($settings)
    {
        return $settings->pluck('value', 'name')->all();
    });

config()->set('settings', $settings);

settings 表:

我能够像这样回显表中的值:

{{ config('settings.sitename') }}  //returns Awesome Images

这适用于任何刀片文件或控制器 App\Http\Controllers

问题:

我试图回应这样的价值App\config\mail.php:

'driver' => config('settings.maildriver'),
'host' => config('settings.mailhost'),

但是我收到了这个错误:

Missing argument 1 for Illuminate\Support\Manager::createDriver()

更新:

我创建了一个新的服务提供程序MailServiceProvider来覆盖Mail.php中的设置,如下所示:

<?php

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use Config;

class MailServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot()
    {
        //
    }

    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
        Config::set('mail.driver', config('settings.maildriver'));
        Config::set('mail.host', config('settings.mailhost'));
        Config::set('mail.port', config('settings.mailport'));
        Config::set('mail.encryption', config('settings.mailencryption'));
        Config::set('mail.username', config('settings.mailusername'));
        Config::set('mail.password', config('settings.mailpassword'));

    }
}

但我仍然得到同样的错误!!

app/config/mail.php在创建swiftmailer传输之前,有没有办法在运行中覆盖默认邮件配置(in )(例如配置存储在数据库中)？

在这个问题上挣扎了3天终于找到了解决问题的方法.

首先,我创建了一个表mails,并用我的值填充它.然后我创建了一个提供者MailConfigServiceProvider.php

<?php

namespace App\Providers;

use Config;
use Illuminate\Support\Facades\DB;
use Illuminate\Support\ServiceProvider;

class MailConfigServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot()
    {
        //
    }

    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
        if (\Schema::hasTable('mails')) {
            $mail = DB::table('mails')->first();
            if ($mail) //checking if table is not empty
            {
                $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);
            }
        }
    }
}

然后在中注册 config\app.php

App\Providers\MailConfigServiceProvider::class,

也许它对某人有用，但我解决了以下问题；

在一个ServiceProvider下boot-method;

$settings = Cache::remember('settings', 60, function () {
    return Setting::pluck('value', 'name')->all();
});

config()->set('settings', $settings); // optional

config()->set('mail', array_merge(config('mail'), [
    'driver' => 'mailgun',
    'from' => [
        'address' => $settings['mail_from_address'],
        'name' => $settings['mail_from_name']
    ]
]));

config()->set('services', array_merge(config('services'), [
    'mailgun' => [
        'domain' => $settings['mailgun_domain'],
        'secret' => $settings['mailgun_secret']
    ]
]));

我使用array_merge了原始配置，所以我们只覆盖了我们需要的值。我们也可以Cache在boot-method 中使用-facade 。
