laravel 中的存储库模式似乎不起作用

Question

App::bind('App\Http\Repositories\languageRepository',
                   function( $app, array $parameters)
{
    return new App\Http\Repositories\languageRepository($parameters[0]);
} );

Route::get('/test/{id}', 'testController@getme');



<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Repositories\languageRepository;
class test extends Controller
{
    //
    protected $language;
    public function __construct(languageRepository $rep){
        $this->language = $rep;
    }


    public function getme(){
        $this->language->getMe();
    }
}

When user accesses the route /test/5 for example, it goes to test Controller. what I'd like to do is that it should automatically pass my route parameter to App:bind function and automatically create languageRepository class with the constructor value passed as my route paramter. what happens is the code actually tells me $parameters[0] is undefined offset. why is that? I've tried App::make but then how do I pass the parameter from route to App::make?

You can accomplish this using the container's request instance, for query parameters:

App::bind('App\Http\Repositories\languageRepository',function($app)
{
    $request = $app['request'];

    $parameters = $request->all();

    return new App\Http\Repositories\languageRepository($parameters[0]);
});

You can accomplish this using the container's request instance, for a route parameter:

App::bind('App\Http\Repositories\languageRepository',function($app)
{
    $request = $app['request'];

    $segment = $request->segment(1);

    return new App\Http\Repositories\languageRepository($segment);
});
