Laravel - interface and multiple services

Question

I need to create an interface to send SMS with multiple providers.

I have create an SMSInterface which contains all the method available to send sms.
Now I have created an abstract class which implements the interfaces:

AbstractSMS.php

<?php

namespace ChristianGiupponi\LaravelSMS\Repositories;

class AbstractSMS implements SMSInterface {

    public function getBalance()
    {
        // TODO: Implement getBalance() method.
    }

    public function getName()
    {
        // TODO: Implement getName() method.
    }

    public function setApiKeys( array $keys )
    {
        // TODO: Implement setApiKeys() method.
    }

    public function to( array $numbers )
    {
        // TODO: Implement to() method.
    }

    public function from( $from )
    {
        // TODO: Implement from() method.
    }

    public function text( $text )
    {
        // TODO: Implement text() method.
    }

    public function send()
    {
        // TODO: Implement send() method.
    }
}

Now for each SMS service I have create a class which extends AbstractSMS:

Nexmo.php

<?php

namespace ChristianGiupponi\LaravelSMS\Repositories\Nexmo;

use ChristianGiupponi\LaravelSMS\Repositories\AbstractSMS;

class Nexmo extends AbstractSMS {

   public function getBalance(){
       return "22";
   }

}

I have also created a service provider to bind the interface to the class based on the config file:

<?php

namespace ChristianGiupponi\LaravelSMS\Providers;

use Illuminate\Support\ServiceProvider;

class LaravelSMSServiceProvider extends ServiceProvider {

    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot()
    {
        /**
         *  Publish config filea
         */
        $this->publishes( [
            __DIR__ . '/Config/sms.php' => config_path( 'sms.php' ),
        ] );
    }

    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
        $this->app->call( [
            $this,
            'registerSMSService'
        ] );
    }

    /**
     *  Register SMS Service
     */
    public function registerSMSService()
    {
        $supportedService = config( 'sms.supported' );
        $defaultService   = config( 'sms.default' );

        $service = ( in_array( $defaultService, $supportedService ) )
            // if the selected one is supported we can use it
            ? $defaultService
            // otherwise just use the system default
            : 'nexmo';

        $service = studly_case( $service );

        // Bind the service
        $this->app->bind( 'ChristianGiupponi\LaravelSMS\Repositories\AbstractSMS', "ChristianGiupponi\LaravelSMS\Repositories\\{$service}\\{$service}" );
    }
}

Then I have created the facade:

<?php

namespace ChristianGiupponi\LaravelSMS\Facades;

use Illuminate\Support\Facades\Facade;

class SMS extends Facade{

    /**
     * Get the registered name of the component.
     *
     * @return string
     */
    protected static function getFacadeAccessor() { return 'abstractsms'; }
}

I have also register the provider and the facada in app.php.
In routes.php I added a simple call:

Route::get('saldo', function(){
    return \ChristianGiupponi\LaravelSMS\Facades\SMS::getBalance();
});

But I get:

ReflectionException in Container.php line 734: Class abstractsms does not exist

With the stack trace:

Where is the error? What am I missinig?

I think the binding in your service provider is wrong. Try with this:

public function registerSMSService()
{
    ...

    // Bind the service
    $this->app->bind( 'abstractsms', "ChristianGiupponi\LaravelSMS\Repositories\\{$service}\\{$service}" );
}

Currently you get an error from the facade because Laravel can't resolve abstractsms, but when you bind abstractsms in the provider it tells Laravel - when the facade needs abstractsms give me an isnatnce of ChristianGiupponi\LaravelSMS\Repositories\{$service}\{$service}.
