README

没有花哨的东西。我只是创建了命令总线，反复复制粘贴。我通常会将大部分业务或应用逻辑从框架控制器（MVC）中移除，并放入命令和处理器中。

但我不想将命令处理器与框架控制器耦合。我想能够通过依赖注入库进行分配和切换。

安装

composer require ericksonreyes/command-bus

示例（Lumen 框架 + Symfony 依赖注入）

Symfony 服务容器配置

services:

  uuid_generator:
    class: App\Services\UuidGenerator

  user_repository:
    class: App\Repositories\UserRepository

  user_registration_service:
    class: Application\Users\Service\UserRegistrationService
    arguments:
    - '@user_repository'

Lumen 控制器

namespace App\Http\Controllers;

use App\Repository\UserRepository;
use Illuminate\Support\Facades\URL;
use Illuminate\Http\Request;
use Illuminate\Http\Response;
use Illuminate\Routing\Controller as BaseController;
use Symfony\Component\DependencyInjection\ContainerInterface;
use Application\Users\UseCase\RegisterUser;

/**
* Class UserRegistrationController
 * @package App\Http\Controllers
 */
class UserRegistrationController extends BaseController {

    /**
     * @param \Symfony\Component\DependencyInjection\ContainerInterface $container
     * @param \Illuminate\Http\Request $request
     * @return \Illuminate\Http\Response
    */
    public function store(
        ContainerInterface $container, 
        Request $request
    ): Response {
        try {
            $url = URL::current();
            $id = $uuidGenerator->generate(prefix: 'user-');
            $uuidGenerator = $container->get('uuid_generator');
            $handler = $container->get('user_registration_service');
            
            $command = new RegisterUser(
                $id,
                $request->get('email'),
                $request->get('password'),
                $request->get('password_confirmation')
            );
            $handler->handleThis($command);
            
            return \response([
                '_embedded' => [
                    '_links' => [
                        'self' => [
                            'href' => url("{$url}/{$id}")
                        ]
                    ],
                    'id' => $id                            
                ]
            ], 201);
        }
        catch (\Exception $exception) {
            $httpCode = 500;
            if ($exception->getCode() >= 400 && $exception->getCode() < 600) {
                $httpCode =$exception->getCode();
            }
            
            return \response([
                '_error' => [
                    'code' => get_class($exception),
                    'message' => $exception->getMessage()            
                ]
            ], $httpCode);
        }
    }
