当会话在Laravel中过期时，将用户重定向到登录页面 [英] Redirect user to login page when session expires in Laravel

问题描述

如果用户会话已过期，我正尝试将其重定向回登录页面.我正在使用Laravel 5.5.我已经编辑了RedirectIfAuthenticated文件，以在handle函数中包含以下代码:

I am trying to redirect a user back to the login page if their session has expired. I am using Laravel 5.5. I have edited my RedirectIfAuthenticated file to include the following code in the handle function:

if (!Auth::check()) {
    return redirect()->route('login', ['account' => 'demo']);
}

当我这样做时，我收到以下错误消息:

When I do this, I am receiving the following error message:

缺少[路由:登录] [URI:/]所需的参数.

Missing required parameters for [Route: login] [URI: /].

我的login路由位于子域路由组内，这就是为什么我要传递account参数的原因.这是我在web.php

My login route is inside a subdomain route group which is why I am passing the account parameter. Here is part of my code in web.php

// Subdomain routing
Route::domain('{account}.ems.dev')->group(function () {
    Route::get('/', 'LoginController@show')->name('login');
}

这是我的LoginController@show代码:

/*
 * Show the login form
 */
public function show($account) {
    // Validate this is a valid subdomain
    $organization = Organization::where('subdomain', $account)->first();

    if ($organization) { 
        return view('login');
    } else {
        return 'This account does not exist.';
    }
}

我没有尝试过任何方法.即使我传入了必需的参数，我仍然收到完全相同的错误消息.

Nothing I have tried works. I keep getting the exact same error message even though I am passing in the required parameters.

仔细研究 Whoops！错误页面后，我看到了，protected function unauthenticated是引起问题的原因:

After a little digging around the Whoops! error page, I see this, protected function unauthenticated is what is causing the problem:

如何覆盖此函数以添加缺少的参数?

How do I override this function to add the missing parameter?

推荐答案

您可以在app/Exceptions/Handler.php文件中覆盖unauthenticated()方法以添加缺少的route参数.

You can override the unauthenticated() method in your app/Exceptions/Handler.php file to add the missing route parameter.

use Illuminate\Auth\AuthenticationException;

class Handler extends ExceptionHandler
{
    protected function unauthenticated($request, AuthenticationException $exception)
    {
        return $request->expectsJson()
            ? response()->json(['message' => $exception->getMessage()], 401)
            : redirect()->guest(route('login', ['account' => $request->route('account')]));
    }
}
