如何在 laravel 5.5.28 中更改默认身份验证密码和用户名

Question

我正在使用自动生成的身份验证设置来登录和注册等。我已经让注册器正常工作，但无法让登录正常工作。

默认情况下，当我运行它时，我会收到此错误

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'email' in 'where clause' (SQL: select * from `consumers` where `email` = jermayne21@gmail.com limit 1)

这可以理解，我的数据库中的电子邮件列是con_email，我的密码列是con_password

我更新了我的LoginController.php 以将email 和password 属性更改为上述列。

LoginController.php

<?php

namespace App\Http\Controllers\Auth;

use Illuminate\Http\Request;
use App\Http\Controllers\Controller;
use Illuminate\Foundation\Auth\AuthenticatesUsers;
use App\User;

class LoginController extends Controller
{
    use AuthenticatesUsers;

    /**
     * Where to redirect users after login.
     *
     * @var string
     */
    protected $redirectTo = '/home';

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest')->except('logout');
    }
    public function username()
    {
      return 'con_email';
    }

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

User.php（供参考）

<?php

namespace App;

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

class User extends Authenticatable
{
    use Notifiable;
    protected $table = 'consumers';
    protected $primaryKey = 'con_id';


    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [ 'con_id', 'con_fname', 'con_lname', 'con_email', 'con_password', 'total_earned'];

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

}

login.blade.php（我认为我不需要更改，如果我错了请纠正我）

从默认代码进行更改后，我不再收到错误消息。当我登录时它只是重新加载到登录屏幕而没有任何验证错误（但似乎它几乎是一个错误的信息但它不是错误的登录信息。

关于我发现的类似问题的其他答案的问题 我没有AuthController.php，但我已经阅读了许多答案，表明在该文件中覆盖它。当我运行php artisan make:auth 时，它会自动生成LoginController.php、ForgotPasswordController.php、RegisterController.php 和ResetPasswordController.php 这是laravel 5.5 中的最新更新（或者可能是根据我阅读的内容在5.2 中完成的）。我在所有控制器中都遇到了相同的当前错误，所以我想AuthController.php 可能已更改为上面的 4 个单独的控制器。

对于 laravel5.5

app/Http/Controllers/Auth/LoginController.php - 新增功能username()

<?php

    namespace App\Http\Controllers\Auth;

    use App\Http\Controllers\Controller;
    use Illuminate\Foundation\Auth\AuthenticatesUsers;

    class LoginController extends Controller
    {
        /*

        | Login Controller
        |--------------------------------------------------------------------------
        |
        | This controller handles authenticating users for the application and
        | redirecting them to your home screen. The controller uses a trait
        | to conveniently provide its functionality to your applications.
        |
        */

        use AuthenticatesUsers;

        /**
         * Where to redirect users after login.
         *
         * @var string
         */
        protected $redirectTo = '/home';

        /**
         * Create a new controller instance.
         *
         * @return void
         */
        public function __construct()
        {
            $this->middleware('guest')->except('logout');
        }

        /**
         * Get the login username to be used by the controller.

         */
        public function username()
        {
            return 'con_email';
        }

    }

Model app/User.php - 添加函数 getAuthPassword()

<?php

    namespace App;

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

    class User extends Authenticatable
    {
        use Notifiable;

        /**
         * The attributes that are mass assignable.
         *
         * @var array
         */
        protected $fillable = [
            'name', 'con_email', 'con_password',
        ];

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


        /**
         * Get the password for the user.
         *
         * @return string
        */

        public function getAuthPassword()
        {
            return $this->attributes['con_password'];
        }
    }

适用于 laravel 5.2

您必须在 Auth/AuthController.php 中覆盖 postLogin() 函数

/**
 * Handle a login request to the application.
 *
 * @param  \Illuminate\Http\Request  $request
 * @return \Illuminate\Http\Response
 */
public function postLogin(Request $request)
{
    $this->validate($request, [
        'email' => 'required|email', 'password' => 'required',
    ]);

    $credentials['con_email'] = $request->input('email');
    $credentials['con_password'] = $request->input('password');

    if ($this->auth->attempt($credentials, $request->has('remember')))
    {
        return redirect()->intended($this->redirectPath());
    }

    return redirect($this->loginPath())
        ->withInput($request->only('email', 'remember'))
        ->withErrors([
            'email' => $this->getFailedLoginMessage(),
        ]);
