A quick and easy way to let authenticated users share the current page using a temporary signed url.

<div>
    @auth

    @endauth

    <script src="https://cdnjs.cloudflare.com/ajax/libs/clipboard.js/2.0.8/clipboard.min.js"></script>
    <script>
        var clipboard = new ClipboardJS('#copy');

        clipboard.on('success', function (e) {
            document.getElementById('copy').innerText = 'Copied!';

            e.clearSelection();

            alert('The link has been copied to your clipboard. Just paste it into a text or email to grant a guest user access to this page for 24 hours.');
        });

SignedOrLoggedIn.php

<?php

namespace App\Http\Middleware;

use Closure;
use Illuminate\Http\Request;

class SignedOrLoggedIn
{
    /**
     * Handle an incoming request.
     *
     * @param  \Illuminate\Http\Request  $request
     * @param  \Closure  $next
     * @return mixed
     */
    public function handle(Request $request, Closure $next)
    {
        if (! auth('web')->check() && ! $request->hasValidSignature(true)) {
            abort(403);
        }
        return $next($request);
    }
}

SignedOrLoggedIn is the middleware I use to protect the routes on which I use this component.
