Laravel Eloquent API 资源：从响应中删除“data”键（集合）

使用 Laravel Eloquent API，我们可以轻松地构建和管理数据库查询。其中一个常见的需求是从 API 响应中删除 "data" 键，特别是当我们返回集合时。在本文中，我们将探讨如何通过编写自定义资源类来实现这一目标。

php
namespace App\Http\Resources;
use Illuminate\Http\Resources\Json\JsonResource;
class UserResource extends JsonResource
{
    public function toArray($request)
    {
        return [
            'id' => $this->id,
            'name' => $this->name,
            'email' => $this->email,
            // 其他用户属性
        ];
    }
}

php
namespace App\Http\Controllers;
use App\Models\User;
use App\Http\Resources\UserResource;
class UserController extends Controller
{
    public function index()
    {
        $users = User::all();
        return UserResource::collection($users);
    }
}

php
namespace App\Http\Resources;
use Illuminate\Http\Resources\Json\JsonResource;
class UserResource extends JsonResource
{
    public function toArray($request)
    {
        return [
            'id' => $this->id,
            'name' => $this->name,
            'email' => $this->email,
            // 其他用户属性
        ];
    }
    public function with($request)
    {
        return [];
    }
    public static function collection($resource)
    {
        return tap(new UserResourceCollection($resource), function ($collection) {
            $collection->collects = __CLASS__;
        });
    }
}
