php - `Class not found` 错误，即使类被定义为模态

Question

我的 Controller 中有以下方法:

public function store(Request $request){
        $data = session()->get('dmca');
        // return $data;
        $notice = Notice::open($date);
        $notice->useTemplate($request->input('template'));
        $notice->save();
        return Notice::first();
    }

当 Controller 运行时，我收到以下错误:

现在我有以下模态类:

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Notice extends Model {

    protected $fillable = [
        'provider_id',
        'infringing_title',    
        'infringing_link',    
        'original_link',    
        'original_description',    
        'template',    
        'content_removed'
    ];


    public static function open(array $attributes) {
        return new static($attributes); 
    } 

    public function useTemplate($template) {
        $this->template = $template;
    }

}

现在为什么我在 laravel class not find 中收到此错误，即使我定义了这个类？？

只需在 Controller 类顶部使用 use 关键字即可。

<?php

namespace App\Http\Controllers;

use App\Notice; // <------------------ use here
use App\Http\Controllers\Controller;

class UserController extends Controller
{
    public function store(Request $request)
    {
        $data = session()->get('dmca');
        // return $data;
        $notice = Notice::open($date);
        $notice->useTemplate($request->input('template'));
        $notice->save();
        return Notice::first();
    }
}

The use keyword helps php to recognize the class Notice within a certain namespace

希望这有帮助!
