Lavavel 程序报错 MassAssignmentException in Model.php line 452: _token

Lavarel 用类似于下面命令插入数据时候出错

Comment::create($request->all())

错误页面截图如下：

错误原因：下面这行代码应该写到对应的Model里面，而不是对应的Controller里面

protected $fillable = ['nickname', 'email', 'website', 'content', 'article_id'];

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class Comment extends Model
{
    protected $fillable = ['nickname', 'email', 'website', 'content', 'article_id'];
}
