如果用户未使用中间件进行身份验证，Laravel 5.4 将重定向到特定页面

Laravel 5.4 redirect to specific page if user is not authenticated using middleware

提问by Antonios Tsimourtos

I want to redirect user, if not authenticated, to my index page (which is the login page)

我想将用户（如果未通过身份验证）重定向到我的索引页面（即登录页面）

Can't seem to make it work and i really got confused with the routing.

似乎无法让它工作，我真的对路由感到困惑。

HomeController

家庭控制器

class HomeController extends Controller
{

    /**
     * Show the application dashboard.
     *
     * @return \Illuminate\Http\Response
     */
    public function index()
    {
        return redirect()->guest('/');
    }
}

Routing

路由

// Index
Route::get('/', [
    'as' => 'index',
    'uses' => 'UserController@index'
]);

UserController

用户控制器

The routing as you see redirects to a User Controllerat indexfunction, which is the below :

您看到的路由重定向到索引函数处的用户控制器，如下所示：

*has __construct()so it uses the middleware 'auth'.

*有__construct()所以它使用中间件 'auth'。

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

public function index(){

    // If user is logged
    if(Auth::check()) {

        // If user has NOT submitted information form redirect there, otherwise to categories
        if(!Auth::user()->submitted_information)
            return redirect()->route('information');
        else
            return redirect()->route('categories');
    }
    else
        return view('index', ['body_class' => 'template-home']);

}

Handler.php

处理程序

And the unauthenticated functioninside middleware of auth (Exceptions/Handler.php)

以及auth 中间件中的未经身份验证的函数（Exceptions/Handler.php）

 protected function unauthenticated($request, AuthenticationException $exception)
    {
        if ($request->expectsJson()) {
            return response()->json(['error' => 'Unauthenticated.'], 401);
        }

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

The error i get right now is the below :

我现在得到的错误如下：

InvalidArgumentException in UrlGenerator.php line 304:
Route [index] not defined.

This error happens because of the line of

发生此错误的原因是

return redirect()->route('index');in the above unauthenticatedfunction.

return redirect()->route('index');在上述未经身份验证的功能中。

What am i missing here? If you need any more information please feel free to ask.

我在这里错过了什么？如果您需要更多信息，请随时询问。

EDIT: Until now, if i remove from UserControllerthe __construct()method, and insert in web.phpto all the routes what middlewareto use, it works.

编辑：到目前为止，如果我从UserController 中删除该__construct()方法，并将其插入web.php到所有middleware要使用的路由中，它就可以工作。

For example

例如

Route::get('/categories', [
    'as' => 'categories',
    'uses' => 'UserController@showCategories'
])->middleware('auth');

But i am trying to find, without specifying there what middleware to use, to use it automatically.

但我试图找到，而不指定使用什么中间件，自动使用它。

Build your route like below code:

像下面的代码一样构建你的路线：

Route::group(['middleware' => ['auth']], function() {
     // uses 'auth' middleware
     Route::resource('blog','BlogController');
});

Route::get('/mypage', 'HomeController@mypage');

Route::get('/mypage', 'HomeController@mypage');

Open your middleware class named RedirectIfAuthenticated and then in handle fucntion you write below code:

打开名为 RedirectIfAuthenticated 的中间件类，然后在句柄功能中编写以下代码：

if (!Auth::check()) {
     return redirect('/mypage'); // redirect to your specific page which is public for all
}

Hope it will work for you.

希望它对你有用。

Your route should be like

你的路线应该是这样的

// Index

// 指数

Route::get('/','UserController@index')->name('index);
