Laravel service provider not binding to contract - php

Question

i have below contract/interface which is binded by a service provider ,however the i get below error :
ReflectionException in RouteDependencyResolverTrait.php line 81:
Class App\Http\Controllers\RocketShipContract does not exist
What am i doing wrong ?
Contract
namespace App\Contracts\Helpers;
Interface RocketShipContract
{
public function blastOff();
}
The concrete class
namespace app\Contracts;
use App\Contracts\Helpers\RocketShipContract;
class RocketShip implements RocketShipContract
{
public function blastOff()
{
return 'Houston, we have ignition';
}
}
The service provider
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'];
}
}
The controller
public function test(RocketShipContract $rocketship)
{
$boom = $rocketship->blastOff();
return view('test.index', compact('boom'));
}

Answer 1

The error you're getting hints at the problem: the class is being resolved in the App\Http\Controllers namespace. That's because you need to specify the full namespace of your interface in the controller.
So either include it with a use statement:
use App\Contracts\Helpers\RocketShipContract;
Or type hint the full namespace:
public function test(App\Contracts\Helpers\RocketShipContract $rocketship)
{
// ...
}
