分析 ：是继承出错了
//错误代码
<?php
namespace App;
use App\Model;
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Model
{
protected $fillable = [
'name', 'email', 'password',
];
}
//正确代码
<?php
namespace App;
use App\Model;
use Illuminate\Foundation\Auth\User as Authenticatable;
class User extends Authenticatable
{
protected $fillable = [
'name', 'email', 'password',
];
}
