他们到处都写说存储库不应该返回 DTO ...那该怎么办？返回对象还是数组？但是你可以在任何地方添加任何东西。如果我更改接收到的数据，那么存储库会立即将其提供给他们，我什至不会注意到它。实际上，DTO 保证我会以单一的形式接收对象，并且在将来我会看到我接受什么以及我给予什么。

如果我突然决定替换它们，我将存储库纯粹用于 CRUD 操作，以便为雄辩的模型提供一层。

告诉我在我的情况下最好的做法是什么？

有这个控制器：

<?php

namespace App\Http\Controllers\Auth;

use Illuminate\Http\Request;
use Illuminate\Http\Response;
use App\Http\Controllers\Controller;

class AuthController extends Controller
{
    /**
     * Handle the incoming request.
     *
     * @return Response
     */
    public function __invoke(Request $request): Response
    {
        return response(auth()->user());
    }
}

这就是它所拥有的一切。解释为什么这样做，为什么它比调用同一用户的单独函数更好？为什么根本需要调用？它是如何使用的？

在 wordpress 的 off-config docker 中有这个项目：

RUN set -ex; \
    curl -o wordpress.tar.gz -fSL "https://wordpress.org/wordpress-${WORDPRESS_VERSION}.tar.gz"; \
    echo "$WORDPRESS_SHA1 *wordpress.tar.gz" | sha1sum -c -; \
# upstream tarballs include ./wordpress/ so this gives us /usr/src/wordpress
    tar -xzf wordpress.tar.gz -C /usr/src/; \
    rm wordpress.tar.gz; \
    chown -R www-data:www-data /usr/src/wordpress

有人可以向我解释为什么他将 wordpress 下载到该文件夹​​吗？它是干什么用的？

该策略具有以下代码：

   public function view(User $user, User $model): bool
    {
        return ($user->id == $model->id || in_array('read_users', $user->access));
    }

第一个模型是登录用户，第二个模型是查看用户。没有任何效果，因为第二种模式不会进入政治领域。

一切从路由开始：

 Route::get('/{id}', [UserController::class, 'show'])->name('users.show')->middleware('can:view,' . User::class);

控制器中不使用模型绑定，因为使用数据库的逻辑放置在存储库中。

在 Windows 上，我正在尝试处理 k8s。有一个启用了 K8s 的 Docker 桌面。但是所有的教程都使用ghost minikube...

据我了解，Minikube 是一个带有仪表板 + 分别为 kubeadm、kubectl 等的 docker 镜像。

但是我已经有 Docker Desktop 的 kubectl 了……我只是一头雾水，解释一下我是否需要 minikube，它到底是做什么的（据我了解，这只是 k8s 的工作环境），它有什么不同来自docker桌面中的k8s？

试图遵循设计模式并在中途陷入困境。任务是这样的，有 3 种发送消息的方式（邮件、短信、电报），邮件中还有 3 个选项（因为程序中有 3 个不同的工作模块，然后是信件的传入数据类型是不同的，就像字母模板本身一样）。

我设法用这样的工厂方法完成了第一部分：

信使界面

<?php

declare(strict_types = 1);

namespace App\Http\Controllers\Email\Interfaces;

interface MessengerInterface
{
    public function send();
}

邮件信使

<?php

declare(strict_types = 1);

namespace App\Http\Controllers\Email;

use App\Http\Controllers\Email\Interfaces\MessengerInterface;

class MailMessenger implements MessengerInterface
{
    public function __construct(
        String $fromAddress,
        String $toAddress,
        Boolean $inbox,
        String $messageText,
        String $messageHtml,
    )
    {

    }

    public function send()
    {
        return '';
    }
}

信使工厂

<?php

declare(strict_types = 1);

namespace App\Http\Controllers\Email\Interfaces;

interface MessengerFactory
{
    public function createMessenger() : MessengerInterface;
}

信使工厂

<?php

declare(strict_types = 1);

namespace App\Http\Controllers\Email;

use App\Http\Controllers\Email\MailMessenger;
use App\Http\Controllers\Email\Interfaces\MessengerFactory;

class MailMessengerFactory implements MessengerFactory
{
    public function createMessenger() : MessengerInterface
    {
        return new MailMessenger;
    }
}

但是如何通过邮件本身内部的模板来分割 - xs. 更准确地说，xs 如何使用设计模式来做到这一点。鉴于我仍然不明白为什么这么简单的事情，使用模板，我需要多达 2 个类，尽管对我来说，1 就足够了

一切似乎都在工作。告诉我如何修复代码，在哪里重构？

<?php

declare(strict_types = 1);

namespace Dummy;

use Illuminate\Database\Seeder;
use Database\Seeds\SequenceTrait;
use App\Models\ColdModule\ColdCustomer;
use App\Models\Tag;

class TagSeeder extends Seeder

    use SequenceTrait;

    protected $taggable = [];

    /**

        $this->taggable = [

    }

    /**

    public function run(): void
    {
        $table     = new Tag;
        $tableName = $table->getTable();
        \DB::table($tableName)->delete();
        for ($i = 0; $i < 50; $i++) {
            factory(Tag::class)->create($this->getTaggable());
        }
        $this->setSequence($tableName);
    }

    /**
     * Return a randomized Model taggables.
     *
     * @return array
     */
    protected function getTaggable(): array
    {
        $rand = array_rand($this->taggable);
        $model = $this->taggable[$rand];
        $ids   = $model->pluck('id')->toArray();
        $type  = get_class($model);

有两种略有不同的配置。Dockerfile 中的第一个具有 COPY 复制整个项目文件夹，然后在 docker-compose 中执行以下操作：

services:
  app:
    build:
      context: .
      dockerfile: Dockerfile
    volumes:
      - /etc/passwd:/etc/passwd:ro
      - /etc/group:/etc/group:ro
      - .:/app:cached
      - home-dir:/home/user:cached
    ports:
      - '4001:8080'
    depends_on:
      - postgres
    networks:
      - app-network

也就是说，您可以看到 :ro 和 :cached。这与我们不复制 dockerfile 并且只在 docker-compose 中写入路径（例如 - home-dir:/home/user）有什么不同？

我读了一本书，慢慢地尝试应用知识。我在视图迁移中创建了一个表，以便稍后引用它，而不是使用 join/groupBy/OrderBy 进行一堆查询。

这是正常的做法吗？我可以根据正常创建的字段对这个虚拟表进行排序吗？我可以执行任何更新/删除操作吗？

有一个没有框架的空项目，但是有一个下载的symfony/router. 这是路由本身：

<?php

use Symfony\Component\Routing\Route;
use Symfony\Component\Routing\RouteCollection;

$routes = new RouteCollection();

$routes->add('contacts_all', new Route('/api/v1/contacts', ['_controller' => 'Controllers\ContactController::index']));
$routes->add('contact_show', new Route('/api/v1/contacts/{contact}', ['_controller' => 'Controllers\ContactController::show']));
$routes->add('contact_delete', new Route('/api/v1/contacts/{contact}', ['_controller' => 'Controllers\ContactController::delete'], [], [], '', ['DELETE']));
$routes->add('api_v1', new Route('/api/{any}', ['_controller' => 'Controllers\AppController::errorApi'], ['any' => '.*']));

$routes->add('index', new Route('/', ['_controller' => 'Controllers\AppController::index']));
$routes->add('any', new Route('/{any}', ['_controller' => 'Controllers\AppController::index'], ['any' => '.*']));

return $routes;

DELETE 方法不起作用，可能是什么问题？

PS：总的来说，我有一个解决方案，但我不喜欢它：

<?php

use Symfony\Component\Routing\Route;
use Symfony\Component\Routing\RouteCollection;

$routes = new RouteCollection();

switch($_SERVER['REQUEST_METHOD'])
{
    case 'GET':
        $routes->add('contacts_all', new Route('/api/v1/contacts', ['_controller' => 'Controllers\ContactController::index']));
        $routes->add('contact_show', new Route('/api/v1/contacts/{contact}', ['_controller' => 'Controllers\ContactController::show']));
        $routes->add('api_v1', new Route('/api/{any}', ['_controller' => 'Controllers\AppController::errorApi'], ['any' => '.*']));
        $routes->add('index', new Route('/', ['_controller' => 'Controllers\AppController::index']));
        $routes->add('any', new Route('/{any}', ['_controller' => 'Controllers\AppController::index'], ['any' => '.*']));
        break;
    case 'DELETE':
        $routes->add('contact_delete', new Route('/api/v1/contacts/{contact}', ['_controller' => 'Controllers\ContactController::delete']));
        break;
}

return $routes;

我想用纯 php 做路由，但后来魔鬼拉我安装 symfony/router，现在我觉得自己像个白痴。我在连接课程时遇到问题，我按照说明进行操作并得到：

Fatal error: Uncaught Error: Class 'AppController' not found in /home/vagrant/html/phb/vendor/symfony/http-kernel/Controller/ControllerResolver.php on line 151

这是他喝的：

<?php

require_once __DIR__.'/../vendor/autoload.php';

use Symfony\Component\Dotenv\Dotenv;
use Symfony\Component\HttpFoundation\Request;
use Symfony\Component\HttpFoundation\Response;
use Symfony\Component\Routing\RouteCollection;
use Symfony\Component\Routing\RequestContext;
use Symfony\Component\Routing\Matcher\UrlMatcher;
use Symfony\Component\Routing\Route;
use Symfony\Component\Routing\Exception\ResourceNotFoundException;
use Symfony\Component\HttpKernel;
use App\Http\Controller\AppController;

$dotenv = new Dotenv();
$dotenv->load(__DIR__.'/../.env');

$request = Request::createFromGlobals();
$routes = new RouteCollection();
$routes->add('main', new Route('/',
        array(
            '_controller' => 'AppController::index',
        )
    )
);


$context = new RequestContext();
$context->fromRequest($request);
$matcher = new UrlMatcher($routes, $context);
$resolver = new HttpKernel\Controller\ControllerResolver();

try {
    $request->attributes->add($matcher->match($request->getPathInfo()));
    $controller = $resolver->getController($request);
    $arguments = $resolver->getArguments($request, $controller);
    $response = call_user_func_array($controller, $arguments);
} catch (ResourceNotFoundException $e) {
    $response = new Response('Not found', 404);
} catch (Exception $e) {
    $response = new Response('Error occurred', 500);
}

$response->send();

我做的愚蠢在哪里？
