Redirect user to login page when session expires in Laravel
提问by three3
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 RedirectIfAuthenticatedfile to include the following code in the handlefunction:
如果他们的会话已过期，我试图将用户重定向回登录页面。我正在使用 Laravel 5.5。我编辑了我的RedirectIfAuthenticated文件以在handle函数中包含以下代码：
if (!Auth::check()) {
return redirect()->route('login', ['account' => 'demo']);
}
When I do this, I am receiving the following error message:
当我这样做时，我收到以下错误消息：
Missing required parameters for [Route: login] [URI: /].
缺少 [Route: login] [URI: /] 的必需参数。
My loginroute is inside a subdomain route group which is why I am passing the accountparameter. Here is part of my code in web.php
我的login路由位于子域路由组内，这就是我传递account参数的原因。这是我的代码的一部分web.php
// Subdomain routing
Route::domain('{account}.ems.dev')->group(function () {
Route::get('/', 'LoginController@show')->name('login');
}
And here is my LoginController@showcode:
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.';
}
}
Nothing I have tried works. I keep getting the exact same error message even though I am passing in the required parameters.
我试过的任何东西都不起作用。即使我传递了所需的参数，我仍然收到完全相同的错误消息。

After a little digging around the Whoops!error page, I see this, protected function unauthenticatedis what is causing the problem:
在对Whoops稍作挖掘之后！错误页面，我看到了这个，protected function unauthenticated是导致问题的原因：
How do I override this function to add the missing parameter?
如何覆盖此函数以添加缺少的参数？
回答by Camilo
You can override the unauthenticated()method in your app/Exceptions/Handler.phpfile to add the missing route parameter.
您可以覆盖文件中的unauthenticated()方法app/Exceptions/Handler.php以添加缺少的路由参数。
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')]));
}
}
