使会话过期重定向回登录？

Question

当用户登录并通过身份验证时，我使用Auth::user()->username;在仪表板上显示用户的用户名。然而，当会话过期类的某种原因，Auth似乎没有工作和仪表板页面抛出错误作为trying to get property of non-object的Auth::user()->username;。当用户单击任何链接或会话过期后刷新页面时，如何将用户重定向回登录页面？

我尝试了 Authenticate.php 中间件，但它总是重定向回登录页面，无论您输入的凭据正确或不正确。但是，当我不使用此中间件时，它会登录用户。我错过了什么吗？

Actions Handled By Resource Controller

Verb        Path                    Action      Route Name
GET         /photo                  index       photo.index
GET         /photo/create           create      photo.create
POST        /photo                  store       photo.store
GET         /photo/{photo}          show        photo.show
GET         /photo/{photo}/edit     edit        photo.edit
PUT/PATCH   /photo/{photo}          update      photo.update

Adding Additional Routes To Resource Controllers

If it becomes necessary to add additional routes to a resource controller beyond the default resource routes, you should define those routes before your call to Route::resource:

Route::get('photos/popular', 'PhotoController@method');

Route::resource('photos', 'PhotoController');

                // return redirect()->guest('auth/login');
                return redirect()->guest('/');

Answer 1

如果会话过期，那么您可以重定向到登录，就像打开此文件 app/Exceptions/Handler.php 添加此代码

public function render($request, Exception $exception)
    {
        if ($exception instanceof \Illuminate\Session\TokenMismatchException) {

            return redirect('/login');

        }

        return parent::render($request, $exception);
    }

Answer 2

您所要做的就是将此构造函数放在仪表板的控制器顶部。似乎 Laravel 已经有一个中间件来处理这个问题。至少我可以从 5.4 及更高版本确认。

public function __construct()
{
    $this->middleware('auth');
}

Answer 3

如果您希望在对应用程序的每个 HTTP 请求期间运行中间件，只需在 app/Http/Kernel.php 类的 $middleware 属性中列出中间件类。因此，为了保护每条路由不被未经身份验证访问，请执行此操作

protected $middleware = [
        'Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode',
        'Illuminate\Cookie\Middleware\EncryptCookies',
        'Illuminate\Cookie\Middleware\AddQueuedCookiesToResponse',
        'Illuminate\Session\Middleware\StartSession',
        'Illuminate\View\Middleware\ShareErrorsFromSession',
        'App\Http\Middleware\VerifyCsrfToken',
        'App\Http\Middleware\Authenticate',// add this line according to your namespace
    ];

如果未登录，它将重定向用户。更新请记住，将auth中间件添加为全局将创建重定向循环，因此请避免它。

或者，如果您希望保护特定路由，则将中间件附加auth到该路由

Route::get('admin/profile', ['middleware' => 'auth', function () {
    //
}]);

我认为您没有将 auth 中间件附加到您的路线上。

Answer 4

创建一个这样的中间件

<?php namespace App\Http\Middleware;

use Closure;
use Illuminate\Contracts\Auth\Guard;

class Authenticate
{
    /**
     * The Guard implementation.
     *
     * @var Guard
     */
    protected $auth;

    /**
     * Create a new filter instance.
     *
     * @param  Guard  $auth
     * @return void
     */
    public function __construct(Guard $auth)
    {
        $this->auth = $auth;
    }

    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if ($this->auth->guest()) {
            if ($request->ajax()) {
                return response('Unauthorized.', 401);
            } else {
                return redirect()->guest('login');
            }
        }
        return $next($request);
    }
}

然后将路线分组并像这样保护它们

Route::group(['middleware' => 'auth'], function()
{
    Route::get();
    Route::get();
    Route::get();
    Route::get();
}

当然，在路由中您必须指定链接等，只有在用户通过身份验证时才会允许用户，如果没有，则会显示登录页面
