使用存储库模式的Laravel策略

<?php

namespace App\Repositories;

use App\Models\Article;

class ArticleRepository
{
    public function getById($id)
    {
        return Article::findOrFail($id);
    }
}

<?php

namespace App\Policies;

use App\Models\User;
use App\Models\Article;
use Illuminate\Auth\Access\HandlesAuthorization;

class ArticlePolicy
{
    use HandlesAuthorization;

    protected $articleRepository;

    public function __construct(ArticleRepository $articleRepository)
    {
        $this->articleRepository = $articleRepository;
    }

    public function view(User $user, Article $article)
    {
        // 根据业务需求，判断用户是否有权限查看文章
        // 可以使用存储库类 $this->articleRepository 访问和操作文章数据
        // 返回 true 表示允许访问，返回 false 表示禁止访问
    }
}

<?php

namespace App\Models;

use App\Policies\ArticlePolicy;
use Illuminate\Database\Eloquent\Model;

class Article extends Model
{
    protected static function boot()
    {
        parent::boot();

        static::creating(function ($article) {
            // 注册策略类
            $article->policy = ArticlePolicy::class;
        });
    }

    public function authorize(User $user, $ability)
    {
        $policy = new $this->policy(new ArticleRepository);
        return $policy->{$ability}($user, $this);
    }
}
