Question

安装身份验证脚手架并创建用于存储使用用户名和密码之外的凭据的数据库后，我正在我的应用程序上进行注册-登录功能。我已经成功注册了新帐户，已存储到数据库中，并重定向到“管理”页面。但是注销后，我无法使用我创建的以前的帐户登录，并且显示了这样的错误消息。

Error message that prevent login

我该怎么办？

这是我的：

web.php

Route::get('/', 'FrontController@home')->name('home');

Route::get('/login', 'FrontController@login')->name('login');

Auth::routes();

Route::get('/home', 'AdminController@index')->name('admin');

Route::get('/manual', 'ManualLoginController@manual')->name('manual');

Route::get('/logout', '\App\Http\Controllers\Auth\LoginController@logout')->name('logout');

LoginController.php

<?php

namespace App\Http\Controllers\Auth;

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

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 logout(Request $request) {
          Auth::logout();
          return redirect('/login');
    }

}

默认情况下，laravel使用email字段进行身份验证，您可以通过在登录控制器中定义以下功能来覆盖它

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

有关详细信息，您可以签入Illuminate\Foundation\Auth\AuthenticatesUsers特性
