ReflectionException 类 App\User 不存在

Question

你好，我有这个错误：ReflectionException Class App\User 不存在 先前的异常语法错误，意外的 '{'，期待 ')' (0)

但不明白语法错误在哪里，

用户.php

<?php

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Contracts\Auth\MustVerifyEmail;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable implements MustVerifyEmail
{
    use Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'username', 'nom', 'prenom', 'adresse', 'ville', 'codepostale', 'datedenaissance','email', 'password',
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];

    /**
     * The attributes that should be cast to native types.
     *
     * @var array
     */
    protected $casts = [
        'email_verified_at' => 'datetime',
    ];

    protected static function boot()
    {
        parent::boot();
        static::created(function ($user {
            $user->profile()->create([
                'title' => 'Profil de' . $user->username
            ]);
        });
    }

    public function getRouteKeyName()
    {
        return 'username';
    }

    public function profile()
    {
        return $this->hasOne('App\Profile');
    }

    public function posts()
    {
        return $this->hasMany('App\Post')->orderBy('created_at', 'DESC');
    }
}

ProfileController.php

<?php

namespace App\Http\Controllers;

use App\User;
use Illuminate\Http\Request;
use Intervention\Image\Facades\Image;

class ProfileController extends Controller
{
    public function show(User $user)
    {
        return view('profile.show', compact('user'));
    }

    public function edit(User $user)
    {
        $this->authorize('update', $user->profile);
        return view('profile.edit', compact('user'));
    }

    public function update(User $user)
    {
        $this->authorize('update', $user->profile);
        $data = request()->validate([
            'title' => 'required',
            'description' => 'required',
            'image' => 'sometimes|image|max:3000'
        ]);

        if (request('image')) {
        $imagePath = request('image')->store('avatars', 'public');

        $image = Image::make(public_path("/storage/{$imagePath}"))->fit(800, 800);
        $image->save();

        auth()->user()->profile->update(array_merge($data,
            ['image' => $imagePath]
        ));
        } else {
            auth()->user()->profile->update($data);
        }

        auth()->user()->profile->update($data);

        return redirect()->route('profile.show', ['user' => $user]);
    }
}

个人资料.php

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Profile extends Model
{
    protected $fillable = ['title']; 

    public function user()
    {
        return $this->belongsTo('App\User');
    }

    public function getImage()
    {
        $imagePath = $this->image ?? 'avatars/default.png';

        return "/storage/" . $imagePath;
    }
}

我尝试使用上传图片创建个人资料，有人可以帮助我解决此错误吗？

您的 IDE 应该会在您重写的

boot

方法中给出错误，因此请更改此：

static::created(function ($user {
    $user->profile()->create([
        'title' => 'Profil de' . $user->username
    ]);
});

对此：

static::created(function ($user) {
   $user->profile()->create([
           'title' => 'Profil de' . $user->username
   ]);
});

注意

)

参数中缺少

$user

。
