Question

我想让用户远离编辑配置文件，所以我在管理面板中创建了用于设置邮件服务器，用户名，密码，端口，加密的Web界面。我在Laravel 4.2中工作得很好，但现在当应用程序被重写为Laravel 5时，会出现错误：

Class 'Settings' not found in <b>F:\htdocs\app\config\mail.php</b> on line <b>18</b><br />

为此，我创建了一个服务提供者，制作了一个外观，将它们放在config / app.php中，Settings::get('var')/Settings::set('var')完美地工作，但不适用于邮件设置。

配置/ mail.php：

<?php return array(
            'driver' => Settings::get('mail_driver'),
            'host' => Settings::get('mail_host'),
            'port' => Settings::get('mail_port'),
            'from' => array('address' => Settings::get('mail_from_address'), 'name' => Settings::get('mail_from_name')),
            'encryption' => Settings::get('mail_encryption'),
            'username' => Settings::get('mail_username'),
            'password' => Settings::get('mail_password'),
            'sendmail' => Settings::get('mail_sendmail'),
            'pretend' => false,
            );

配置/ app.php：

'providers' => [

    ...

    'App\Providers\SettingsServiceProvider',

    ...

'aliases' => [

    ...

    'Settings' => 'App\Custom\Facades\Settings',

<?php namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use App\Custom\Settings;

class SettingsServiceProvider extends ServiceProvider {

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

/**
 * Register the application services.
 *
 * @return void
 */
public function register()
{
    $this->app->singleton('settings', function()
    {
        return new Settings;
    });
}

}

<?php namespace App\Custom;

use App\Setting;

class Settings {
public function get($var) {

    try{
        $setting = Setting::first();                

    } catch(exception $e)
    {
        return false;
    }

    return $setting->$var;

}

public function set($var, $val) {

    try{
        $setting = Setting::first();
        $setting->$var = $val;              
        $setting->save();               

    } catch(exception $e)
    {
        return false;
    }

    return true;

}   
}

<?php

namespace App\Custom\Facades;

use Illuminate\Support\Facades\Facade;

class Settings extends Facade {

    protected static function getFacadeAccessor() { return 'settings'; }

}

有关如何使用数据库实现Laravel邮件设置的任何想法吗？

Answer 1

要归档此内容，我通过扩展CustomMailServiceProvider创建了Illuminate\Mail\MailServiceProvider，以覆盖此方法：

protected function registerSwiftTransport(){
    $this->app['swift.transport'] = $this->app->share(function($app)
    {
    return new TransportManager($app);
    });
}

以下是完整的解决方案

我在app \ Providers

namespace App\Providers;

use Illuminate\Mail\MailServiceProvider;
use App\Customs\CustomTransportManager;

class CustomMailServiceProvider extends MailServiceProvider{

    protected function registerSwiftTransport(){
        $this->app['swift.transport'] = $this->app->share(function($app)
        {
            return new CustomTransportManager($app);
        });
    }
}

我在app / customs目录中创建了CustomTransportManager.php - 注意：app / customs目录在默认的laravel 5目录结构中不存在，我创建了它

namespace App\Customs;

use Illuminate\Mail\TransportManager;
use App\Models\Setting; //my models are located in app\models

class CustomTransportManager extends TransportManager {

    /**
     * Create a new manager instance.
     *
     * @param  \Illuminate\Foundation\Application  $app
     * @return void
     */
    public function __construct($app)
    {
        $this->app = $app;

        if( $settings = Setting::all() ){

            $this->app['config']['mail'] = [
                'driver'        => $settings->mail_driver,
                'host'          => $settings->mail_host,
                'port'          => $settings->mail_port,
                'from'          => [
                'address'   => $settings->mail_from_address,
                'name'      => $settings->mail_from_name
                ],
                'encryption'    => $settings->mail_encryption,
                'username'      => $settings->mail_username,
                'password'      => $settings->mail_password,
                'sendmail'      => $settings->mail_sendmail,
                'pretend'       => $settings->mail_pretend
           ];
       }

    }
}

最后，我用'Illuminate\Mail\MailServiceProvider',

'App\Providers\CustomMailServiceProvider',

Answer 2

我添加了

$this->app['config']['services'] = [
        'mailgun' => [
            'domain' => $settings->mailgun_domain,
            'secret' => $settings->mailgun_secret,
        ]
        ];

到CustomTransportManager __construct（）以包含我用作邮件服务的mailgun API凭据

Answer 3

我配置如上所述，但是出现以下错误。虽然我尝试了你的代码，但是发现Laravel 5.4的方法已被弃用，而是被告知要使用singleton。

Call to undefined method Illuminate\Foundation\Application::share()

以下是使用singleton而不是使用share方法的方法：

protected function registerSwiftTransport(){
    $this->app->singleton('swift.transport', function ($app){
        return new CustomTransportManager($app);
    });
}

Answer 4

@DigitLimit，方法share（）自Laravel 5.4以来已被删除。我不得不使用其他方法解决这个问题，我不确定它们是否完美。这是CustomMailServiceProvider类中的registerSwiftTransport（）方法。

首先，我们需要确定在通过命令行调用app时是否未执行代码：“if（strpos（php_sapi_name（），'cli'）=== false）”。如果我们不检查并且不防止在这种情况下设置新的参数，Artisan将在命令行中抛出错误。其次，我们需要以某种方式从数据库中获取设置。我使用我的方法getSettingValue（）完成它，其中第一个参数是设置键，第二个参数是默认值，如果找不到设置。如您所见，我已将设置分配给$ this-＆gt; app ['config'] ['mail']。之后，我使用了singleton（）方法：

protected function registerSwiftTransport(){
    if (strpos(php_sapi_name(), 'cli') === false) {
       $this->app['config']['mail'] = [
        'driver'        => Setting::getSettingValue('mail_driver', '****'),
        'host'          => Setting::getSettingValue('mail_host', '****'),
        'port'          => Setting::getSettingValue('mail_port', 25),
        'from'          => [
            'address'   => Setting::getSettingValue('mail_from_address', '****'),
            'name'      => Setting::getSettingValue('mail_from_name', '****'),
        ],
        'encryption'    => Setting::getSettingValue('mail_encryption', '***'),
        'username'      => Setting::getSettingValue('mail_username', '****'),
        'password'      => Setting::getSettingValue('mail_password', '****'),
     ];
   }

   $this->app->singleton('swift.transport', function ($app) { 
       return new Illuminate\Mail\TransportManager($app);
   });
}
