Question

我需要在Laravel 5应用程序中设置facade别名，但我希望它仅在我的local environment中可用。

我尝试添加的存储库是Laravel-Debugbar。

所以我以这种方式在Http/Providers/AppServiceProvider注册了提供商：

public function register()
{
    if( $this->app->environment() == "local")
    {
        $this->app->register('Barryvdh\Debugbar\ServiceProvider');
    }
}

如何为别名执行相同操作？

'Debugbar' => 'Barryvdh\Debugbar\Facade',

Answer 1

按以下步骤进行。

1）在你的composer require命令中添加“--dev”。即

 sudo composer require barryvdh/laravel-ide-helper --dev

或者，在composer.json中，将您的开发环境需要转移到“require-dev”部分：

"require": {
    "laravel/framework": "5.0.*"
},
"require-dev": {
    "laracasts/generators": "~1.1",
    "barryvdh/laravel-ide-helper": "~2.0",
    "barryvdh/laravel-debugbar": "~2.0"
},

然后做作曲家更新。

2）设置一个新的ServiceProvider：

php artisan make:provider LocalEnvironmentServiceProvider

3）在config / app中将LocalEnvironmentServiceProvider添加到providers数组：

'providers' => [ ...
    'app\Providers\ConfigServiceProvider',
    'app\Providers\EventServiceProvider',
    'app\Providers\RouteServiceProvider',

   /*
    * Our Local Environment Service Providers...
    */
    'app\Providers\LocalEnvironmentServiceProvider',
],

4）修改新的app / Providers / LocalEnvironmentServiceProvider文件：

<?php namespace App\Providers;

use Illuminate\Foundation\AliasLoader;
use Illuminate\Support\ServiceProvider;

class LocalEnvironmentServiceProvider extends ServiceProvider {

    /**
     * List of Local Environment Providers
     * @var array
     */
    protected $localProviders = [
        'Laracasts\Generators\GeneratorsServiceProvider'
        'Barryvdh\Debugbar\ServiceProvider',
        'Barryvdh\LaravelIdeHelper\IdeHelperServiceProvider',
    ];

    /**
     * List of only Local Environment Facade Aliases
     * @var array
     */
    protected $facadeAliases = [
        'Debugbar' => 'Barryvdh\Debugbar\Facade',
    ];

    /**
     * Bootstrap the application services.
     * @return void
     */
    public function boot() {
        if ($this->app->isLocal()) {
            $this->registerServiceProviders();
            $this->registerFacadeAliases();
        }
    }

    /**
     * Register the application services.
     * @return void
     */
    public function register() {
    }

    /**
     * Load local service providers
     */
    protected function registerServiceProviders() {
        foreach ($this->localProviders as $provider) {
            $this->app->register($provider);
        }
    }

    /**
     * Load additional Aliases
     */
    public function registerFacadeAliases() {
        $loader = AliasLoader::getInstance();
        foreach ($this->facadeAliases as $alias => $facade) {
            $loader->alias($alias, $facade);
        }
    }
}

我还在其中添加了其他几个典型的开发提供商和外观，所以希望您能够轻松了解扩展它的难易程度。

使用此方法，您只需更改$ this-＆gt; app-＆gt; isLocal（）以匹配其他环境。

您可以添加别名，就像您对ServiceProvider所做的一样。在Http/Providers/AppServiceProvider更新register方法，如下所示：

public function register()
{
    if ($this->app->environment() == 'local') {
        // Providers
        $this->app->register('Barryvdh\Debugbar\ServiceProvider');

        // Aliases
        $this->app->alias('Debugbar', 'Barryvdh\Debugbar\Facade');
    }
}

Laravel - 仅为本地环境添加别名
