Laravel中间件将用户信息返回为null

我创建了一个中间层，以防止用户不插入或更新任何内容。我在拉威尔5.6频道

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Support\Facades\Auth;
class LimitDemoUser
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        $userId = Auth::id();
        if(request()->method() != "GET" && request()->method() != "HEAD" && $userId == 6) {
            abort(403);
        }
        return $next($request);
    }
}

但是当我dd（Auth:：id（））时；我得到的是null而不是loggedin用户id

我错过了什么

我想我不必在RouteMiddle软件中添加任何内容

protected $routeMiddleware = [
    'auth' => \Illuminate\Auth\Middleware\Authenticate::class,
    'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
    'bindings' => \Illuminate\Routing\Middleware\SubstituteBindings::class,
    'cache.headers' => \Illuminate\Http\Middleware\SetCacheHeaders::class,
    'can' => \Illuminate\Auth\Middleware\Authorize::class,
    'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
    'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,

];

我的登录控制器在下面。也许会有帮助

<?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 = '/login';

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

    public function logout()
    {
        $this->guard()->logout();

        return redirect()->route('login');
    }

}

您的登录控制器应如下所示：

class LoginController extends Controller
{
    /**
     * Handle an authentication attempt.
     *
     * @return Response
     */
    public function authenticate()
    {
        if (Auth::attempt(['email' => $email, 'password' => $password])) {
            // Authentication passed...
            return redirect()->intended('dashboard');
        }
    }
}

当您想要获得用户id时，您应该访问用户类

if (Auth::check())
{
    // The user is logged in...
    Auth::user()->id;
}
else
{
    echo "You are not logged in";
}

尝试将web.php更改为

Route::middleware(['limitdemouser'])->group(function () {
  Auth::routes();
});

你的$RouteMiddle软件是

protected $routeMiddleware = [
    'auth' => \Illuminate\Auth\Middleware\Authenticate::class,
    'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
    'bindings' => \Illuminate\Routing\Middleware\SubstituteBindings::class,
    'cache.headers' => \Illuminate\Http\Middleware\SetCacheHeaders::class,
    'can' => \Illuminate\Auth\Middleware\Authorize::class,
    'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
    'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
    'limitdemouser' => \App\Http\Middleware\LimitDemoUser::class,
];

如果不起作用，请告诉我。
我在本页找到了解决方案。

OP声明

i have added the following code in the global middleware and nou is het working 
\App\Http\Middleware\EncryptCookies::class, \Illuminate\Session\Middleware\StartSession::class,

它很脏，但它起作用了。我不认为这是最好的做法，但它解决了问题。既然我们发现了问题，有人能从这里提出一个合适的解决方案吗？
将
\App\Http\Middleware\LimitDemoUser:：class
添加到
web
中间件组数组的末尾

protected $middlewareGroups = [
    'web' => [
        ...,
        \App\Http\Middleware\LimitDemoUser::class,
     ]
];

你的路线代码是什么我没有在$RouteMiddle软件中添加任何内容，是吗？你的web.php文件$userId=Auth:：user（）->id@afsalc对于登录我只有Auth:：routes（）；我试图获取非对象错误dd的属性（Auth:：user（））也返回null是的，它表示您未登录，但我已登录：）我是否应该向中间件声明我已登录的内容？@SNaRe，您确定您已登录吗？是的，因为当我删除其他内容时，我进入了我已登录的页面umm！你的问题是你的日志控制器。在你写这篇文章之前，我只是尝试一下。但它也不起作用。这对Laravel 5.8不起作用。我也有同样的问题。对我来说最好的答案是：解决了我非常相似的问题。
protected $middlewareGroups = [
    'web' => [
        ...,
        \App\Http\Middleware\LimitDemoUser::class,
     ]
];
