用户登录在带有 sql server 的 laravel 中不起作用。 之前创建的数据库

Question

我正在开发一个 sql server 上的数据库已经存在的项目，所以我必须更改表和列的名称才能运行用户注册表。 注册工作正常，现在，登录不起作用。 尝试登录时，页面什么也不做，只是重新加载。 如果你能帮助我，我将不胜感激，谢谢

------------User model--------------
 <?php

namespace App;

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

class User extends Authenticatable
{
    protected $table = 'tb_postulantes';
    protected $primaryKey = 'id_postulante';

    use Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'nombre_postulante',  'appaterno_postulante', 'correo_postulante', 'password_postulante',
        'apmaterno_postulante', 'telefono_postulante', 'fechaingreso_postulante', 'estado_postulante'





    ];

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

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

    */

    use AuthenticatesUsers;


    /**
     * Where to redirect users after login.
     *
     * @var string

    /**

    public function __construct()

        $this->middleware('guest')->except('logout');

    public function beforelogin()
    {

        return view('Auth.beforelogin');
    }
}

Answer 1

首先，Laravel 身份验证使用字段“电子邮件”来登录用户 - 您的用户模型中没有此字段，因此如果您想更改它，您必须在 LoginController 中定义用户名，如下所示：

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

对于不同的密码字段，您可以在您的用户模型中使用访问器，如下所示：

public function getAuthPassword()
{
    return $this->password_postulante;
}

您可以在 Laravel 文档https://laravel.com/docs/5.5/authentication#included-authenticating 中找到更多信息

但是，如果您想使用所有三个参数来登录用户，我建议您使用不同的逻辑制作自己的 LoginController。
