是否可以使用PHP-DI定义而不是Slim 3中IoC内置的雄辩胶囊管理器？

我目前正在开发一个slim 3应用程序，该应用程序使用桥接来服务依赖项。控制器中的一切都在完美地工作，然而，我在尝试向模型观察者添加依赖项时遇到了一个问题。Eloquents capsule manager有自己的容器，因此我无法通过依赖项（未注入）而不抛出错误

当前设置：

$app = new \App\App; // extends \DI\Bridge\Slim\App
$container = $app->getContainer();

$capsule = new Capsule;
$capsule->addConnection($settings['settings']['db']);
$capsule->setEventDispatcher(new Dispatcher());
$capsule->setAsGlobal();
$capsule->bootEloquent();

// Sale model extends eloquent model
Sale::observe(new SaleObserver($container));

class SaleObserver {

    protected $container;

    public function __construct($container){
        $this->container = $container;
    }
    public function saving(Sale $sale){

        // Mail logic using container

    }

}

Unresolvable dependency resolving [Parameter #0 [ <required> $container ]]

Uncaught ArgumentCountError: Too few arguments to function

SaleObserver类：

$app = new \App\App; // extends \DI\Bridge\Slim\App
$container = $app->getContainer();

$capsule = new Capsule;
$capsule->addConnection($settings['settings']['db']);
$capsule->setEventDispatcher(new Dispatcher());
$capsule->setAsGlobal();
$capsule->bootEloquent();

// Sale model extends eloquent model
Sale::observe(new SaleObserver($container));

class SaleObserver {

    protected $container;

    public function __construct($container){
        $this->container = $container;
    }
    public function saving(Sale $sale){

        // Mail logic using container

    }

}

Unresolvable dependency resolving [Parameter #0 [ <required> $container ]]

Uncaught ArgumentCountError: Too few arguments to function

这给了我SaleObserver触发的错误：

$app = new \App\App; // extends \DI\Bridge\Slim\App
$container = $app->getContainer();

$capsule = new Capsule;
$capsule->addConnection($settings['settings']['db']);
$capsule->setEventDispatcher(new Dispatcher());
$capsule->setAsGlobal();
$capsule->bootEloquent();

// Sale model extends eloquent model
Sale::observe(new SaleObserver($container));

class SaleObserver {

    protected $container;

    public function __construct($container){
        $this->container = $container;
    }
    public function saving(Sale $sale){

        // Mail logic using container

    }

}

Unresolvable dependency resolving [Parameter #0 [ <required> $container ]]

Uncaught ArgumentCountError: Too few arguments to function

我最终得到了一个不同的错误，这表明PHPDI自动连接不能与未连接到路由的类一起工作，即使自动连接被设置为true，因为注入的参数没有自动实例化

这显示错误：

$app = new \App\App; // extends \DI\Bridge\Slim\App
$container = $app->getContainer();

$capsule = new Capsule;
$capsule->addConnection($settings['settings']['db']);
$capsule->setEventDispatcher(new Dispatcher());
$capsule->setAsGlobal();
$capsule->bootEloquent();

// Sale model extends eloquent model
Sale::observe(new SaleObserver($container));

class SaleObserver {

    protected $container;

    public function __construct($container){
        $this->container = $container;
    }
    public function saving(Sale $sale){

        // Mail logic using container

    }

}

Unresolvable dependency resolving [Parameter #0 [ <required> $container ]]

不幸的是，我正在使用的桥接器看起来像是Laravel的数据库事件处理机制严重依赖于Laravel的容器实现。阅读后，我设法使事件按预期进行

我设置了

\illumb\Container\Container

的一个实例，并将其添加到我的应用程序容器（

$Container

）中并将其使用。此Laravel容器实例将仅用于处理事件。现在，我可以设置

\illumb\Events\Dispatcher

的实例，并将其注册到设置管理器实例：

$container['laravel-container'] = function ($c){
    return new \Illuminate\Container\Container;
};

$container['database-event-dispatcher'] = function ($c) {
    return new \Illuminate\Events\Dispatcher($c['laravel-container']);
};

$capsule = new \Illuminate\Database\Capsule\Manager();
$capsule->addConnection($container['settings']['db']);
// Pass event dispatcher instance from application container
$capsule->setEventDispatcher($container['database-event-dispatcher']);
$capsule->setAsGlobal();
// Now that we're using events it is important to call $capsule->bootEloquent();
$capsule->bootEloquent();

$container ['mailer'] = function ($c) {
    // set up and return a MailerInterface
};

Sale::observe(new SaleObserver($container['mailer']));

A当创建观察者的新实例时，我们可以传递应用程序

$container

，或者只传递观察者中需要的对象

因此，假设这是我们的

SaleObserver

类：

class SaleObserver {

    protected $mail;

    public function __construct(MailerInterface $mail){
        $this->mail = $mail;
    }

    public function updating(Sale $sale){
        // Send Mail logic
    }

}

我们应该给它一个mailer实例：

$container['laravel-container'] = function ($c){
    return new \Illuminate\Container\Container;
};

$container['database-event-dispatcher'] = function ($c) {
    return new \Illuminate\Events\Dispatcher($c['laravel-container']);
};

$capsule = new \Illuminate\Database\Capsule\Manager();
$capsule->addConnection($container['settings']['db']);
// Pass event dispatcher instance from application container
$capsule->setEventDispatcher($container['database-event-dispatcher']);
$capsule->setAsGlobal();
// Now that we're using events it is important to call $capsule->bootEloquent();
$capsule->bootEloquent();

$container ['mailer'] = function ($c) {
    // set up and return a MailerInterface
};

Sale::observe(new SaleObserver($container['mailer']));

可以将

连接

对象与空的Laravel容器一起使用，如下所示：

use Illuminate\Database\Connection;
use Illuminate\Database\Connectors\ConnectionFactory;
use Psr\Container\ContainerInterface as Container;

$container[Connection::class] = function (Container $container) {
    $settings = $container->get('settings');
    $config = [
        'driver' => 'mysql',
        'host' => $settings['db']['host'],
        'database' => $settings['db']['database'],
        'username' => $settings['db']['username'],
        'password' => $settings['db']['password'],
        'charset' => $settings['db']['charset'],
        'collation' => $settings['db']['collation'],
        'prefix' => '',
    ];

    $factory = new ConnectionFactory(new \Illuminate\Container\Container());
    $connection = $factory->make($config);

    // Disable the query log to prevent memory issues
    $connection->disableQueryLog();

    return $connection;
};

也许你需要键入提示类/接口名，这样PHP-DI可以自动连接它们。我更新了我的问题以反映你的输入，这实际上是我尝试的第一件事，我不相信PHP DI/slim bridge会注意到任何未连接到路由请求的类。
