Question

我尝试使用ajax登录管理员。但是我遇到了这个错误。我不知道第0列来自哪里。

SQLSTATE [42S22]：未找到列：1054“where”中的未知列“0” 子句''（SQL：select * from users where 0 = admin limit 1）

这是我的代码

public function login()
{
    $username= Input::get('username');
    $password= Input::get('password');
    $admin=array([
        'username'=>$username,
        'password'=>$password,
        'level'=>1
        ]);
    if ($this->auth->attempt($admin)) {
        return "ok";
    }
    else {
        return "fail";
    }
}

模型

<?php namespace App;

use Illuminate\Auth\Authenticatable;
use Illuminate\Database\Eloquent\Model;
use Illuminate\Contracts\Auth\Authenticatable as AuthenticatableContract;


class User extends Model implements AuthenticatableContract
{

    use Authenticatable;

    /**
     * The database table used by the model.
     *
     * @var string
     */
    protected $table = 'users';

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = ["username","password",'level'];

    /**
     * The attributes excluded from the model's JSON form.
     *
     * @var array
     */
    protected $hidden = ['password'];
    public $timestamps = false;


}

问题是您的$admin数组。你已经混合了两种用于创建数组的语法，并且你不小心创建了一个数组数组。

您需要将$admin数组更改为：

$admin = array(
    'username'=>$username,
    'password'=>$password,
    'level'=>1
);

或：

$admin = [
    'username'=>$username,
    'password'=>$password,
    'level'=>1
];
