Laravel中间件在laravel 5.4中不起作用

Question

我有以下代码

<?php

namespace App\Http\Middleware;

use Closure;
use Session;

class CheckLogin
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle($request, Closure $next)
    {
        if(!Session::has('userAuthDetail')){
            // return redirect('login');
            // return redirect()->guest('/login');
        } else {
            return $next($request);     
        }
    }
}

在web.php中

Route::get('/login', ['as' => 'login', 'uses' => 'Auth\LoginController@login']);

Route::group(['middleware' => ['login']], function () {
    Route::post('/add','MyController@submitData');
});

登录控制器

public function postLogin(Request $request) {
     //    print_r($request->all());

     $data['email']=$request->email;
     $data['password']=$request->password;
     $response=  ApiModel::userLogin($data);
     if($response->msg=='success'){
         session(['userAuthDetail' => $response->data[0]]);
         return redirect('/');
    } else if($response->msg=='failed'){
         return redirect('/');
    }   
}

如果我添加中间件中的其他条件，则网站抛出错误

VerifyCsrfToken.php第156行中的ErrorException：试图获取非对象的属性

如果我删除，否则添加

public function handle($request, Closure $next)
{
   if(!Session::has('userAuthDetail')){

   } 
   return $next($request);      
}

然后工作正常，但如果凭据失败，则将其重定向到仪表板。

注意：由于我正在与用核心php编写的api通信，因此我不能使用laravel auth

kernal.php

<?php

namespace App\Http;

use Illuminate\Foundation\Http\Kernel as HttpKernel;

class Kernel extends HttpKernel
{
    /**

     *

    protected $middleware = [

        \App\Http\Middleware\TrimStrings::class,

    ];

    /**

     *

     */
    protected $middlewareGroups = [
        'web' => [

        'api' => [
            'throttle:60,1',
            'bindings',
        ],
    ];

    /**

     *
     * These middleware may be assigned to groups or used individually.
     *
     * @var array
     */
    protected $routeMiddleware = [
        'auth' => \Illuminate\Auth\Middleware\Authenticate::class,
        'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,

        'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
        'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
        'login' => \App\Http\Middleware\CheckLogin::class,
    ];
}

Answer 1

如果未创建用户会话，则应返回登录页面

public function handle($request, Closure $next)
{
    if(!Session::has('userAuthDetail')){
         //return to login page
    } 
    return $next($request);//if session exist then forward the request     
}

Answer 2

VerifyCsrfToken.php的第156行显示它试图调用$response->headers->setCookie(...) 。 您的错误表明$ response为null，这就是if(!Session::has('userAuthDetail')) { ... }方案在CheckLogin中间件中会发生的情况。

基本上，您有一个中间件返回null（或根本不返回任何东西，这种情况在PHP世界中被视为null）。 这是不允许的，中间件必须始终返回某种响应（或引发异常）。

TL; DR：您的中间件必须返回所有执行路径的响应。
