Answer 1

您必须在应用程序的config/session.php文件中增加会话时间。

/*
    |--------------------------------------------------------------------------
    | Session Lifetime
    |--------------------------------------------------------------------------
    |
    | Here you may specify the number of minutes that you wish the session
    | to be allowed to remain idle before it expires. If you want them
    | to immediately expire on the browser closing, set that option.
    |
    */

    'lifetime' => 120,

    'expire_on_close' => false,

Answer 2

您需要在app \ Exceptions \ Handler.php中添加TokenMismatchException

use Illuminate\Session\TokenMismatchException;

class Handler extends ExceptionHandler {

public function render($request, Exception $e) {


         if ($e instanceof TokenMismatchException){
            //redirect to a form when there is token mismatch
            return redirect($request->fullUrl())->with('alert-warning',"Opps! Seems you couldn't submit form for a longtime. Please try again");
        }

        //Remaining code 
        .
        .
        .
        .

    }

}
