Php Laravel服务提供商不受合同约束

我有以下由服务提供商绑定的合同/接口，但我得到以下错误：

RoutedPendencySolvertRait.php第81行中的ReflectionException： 类App\Http\Controllers\RocketShipContract不存在

我做错了什么

合同

namespace App\Contracts\Helpers;

Interface RocketShipContract
{

    public function blastOff();


}

混凝土类

namespace app\Contracts;

use App\Contracts\Helpers\RocketShipContract;

class RocketShip implements RocketShipContract
{

    public function blastOff()
    {

        return 'Houston, we have ignition';

    }

}

服务提供商

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use App\Contracts\RocketShip;

class RocketShipServiceProvider extends ServiceProvider
{
    protected $defer = true;

    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot()
    {
        //
    }
    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
        $this->app->bind('App\Contracts\Helpers\RocketShipContract', function($app){

            return new  App\Contracts\RocketShip($app['HttpClient']);

        });
    }

    /**
     * Get the services provided by the provider.
     *
     * @return array
     */
    public function provides()
    {
        return ['App\Contracts\Helpers\RocketShipContract'];
    }

}

public function test(RocketShipContract $rocketship)
    {
         $boom = $rocketship->blastOff();

        return view('test.index', compact('boom'));
    }

控制器

namespace App\Providers;

use Illuminate\Support\ServiceProvider;
use App\Contracts\RocketShip;

class RocketShipServiceProvider extends ServiceProvider
{
    protected $defer = true;

    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot()
    {
        //
    }
    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
        $this->app->bind('App\Contracts\Helpers\RocketShipContract', function($app){

            return new  App\Contracts\RocketShip($app['HttpClient']);

        });
    }

    /**
     * Get the services provided by the provider.
     *
     * @return array
     */
    public function provides()
    {
        return ['App\Contracts\Helpers\RocketShipContract'];
    }

}

public function test(RocketShipContract $rocketship)
    {
         $boom = $rocketship->blastOff();

        return view('test.index', compact('boom'));
    }

您得到的问题提示错误：正在

App\Http\Controllers

命名空间中解析该类。这是因为您需要在控制器中指定接口的完整名称空间

因此，要么将其包含在

use

语句中：

use App\Contracts\Helpers\RocketShipContract;

或键入完整命名空间的提示：

public function test(App\Contracts\Helpers\RocketShipContract $rocketship)
{
    // ...
}

---

接口现在被称为i，但是现在我得到这个错误

Target[App\Helpers\Contracts\RocketShipContract]不可实例化。

你的

RocketShipServiceProvider

是否添加到

config/App.php

中的

providers

数组中？
