Laravel Package 開發：未找到外觀別名

Question

我嘗試為 Laravel 7 package 中的外觀創建別名。

在測試時，我收到消息：

錯誤：未找到 Class 'MemberRequest'

測試：

    /** @test */
    public function a_member_request_can_be_created()
    {
        $this->assertDatabaseMissing('member_requests', ['created_at' => Date::now()]);
        \MemberRequest::create(new CreateMemberRequestRequest(['email_address' => $this->email_address]));
        $this->assertDatabaseHas('member_requests', ['created_at' => Date::now()]);
    }

我做了以下步驟：

• 創建一個門面（從 Laravel 擴展門面 class
• 在服務提供者中注冊
• 將別名添加到配置文件
• 將別名添加到 composer.json 文件

創建立面：

namespace martijn\UMS\Repositories\Facades;

use Illuminate\Support\Facades\Facade;

class MemberRequestRepositoryFacade extends Facade
{
    public static function getFacadeAccessor()
    {
        return 'MemberRequest';
    }
}

在 serviceProvider 中注冊：

namespace martijn\UMS\Providers;


use Illuminate\Support\ServiceProvider;
use martijn\UMS\Repositories\MemberRequestRepository;

class UMSBaseServiceProvider extends ServiceProvider
{
public function register()
    {
        $this->registerFacades();
    }

    private function registerFacades()
    {
        // Facades
        $this->app->singleton('MemberRequest', function () {
            return new MemberRequestRepository();
        });
    }
}

將其添加到配置文件中：

return [


    /*
    |--------------------------------------------------------------------------
    | Class Aliases
    |--------------------------------------------------------------------------
    |
    | This array of class aliases will be registered when this application
    | is started. However, feel free to register as many as you wish as
    | the aliases are "lazy" loaded so they don't hinder performance.
    |
    */

    'aliases' => [
        'MemberRequest' => \martijn\UMS\Repositories\Facades\MemberRequestRepositoryFacade::class,
    ]
];

將其添加到 composer.json：

      "aliases": {
        "MemberRequest": "martijn\\UMS\\Repositories\\Facades\\MemberRequestRepositoryFacade"
      }

Answer 1

在您的ServiceProvider中，嘗試如下：

$this->app->singleton('MemberRequest', function () {
   return new MemberRequestRepository;
});

Answer 2

我發現它是在服務提供商的引導加載程序中完成的，如下所示：

https://laracasts.com/discuss/channels/laravel/dynamic-class-aliases-in-package

在我的例子中是：

$loader = AliasLoader::getInstance();
$loader->alias('MemberRequest', \martijn\UMS\Repositories\Facades\MemberRequestRepositoryFacade::class);
