Why authentication secures applications in Laravel - See It in Action

Why authentication secures applications

📖 Scenario: You are building a simple Laravel web application that shows a secret message only to logged-in users. This helps protect sensitive information from strangers.

🎯 Goal: Create a Laravel route and controller that shows a secret message only if the user is authenticated. Otherwise, it redirects to the login page.

📋 What You'll Learn

Create a route named /secret that uses a controller method SecretController@show

Add middleware auth to the route to require login

Create a controller SecretController with a show method

Return a view named secret from the show method

Create a Blade view secret.blade.php that displays the text This is a secret message for authenticated users only.

💡 Why This Matters

Understanding authentication and middleware is essential for backend web developers working with Laravel or similar frameworks.

1

Create the route for the secret page

In the routes/web.php file, create a route for /secret that uses the controller method SecretController@show.

Laravel

// Your code here

Use Route::get('/secret', [SecretController::class, 'show']); to define the route.

2

Add authentication middleware to the route

In routes/web.php, add the auth middleware to the /secret route to require users to be logged in.

Laravel

<?php

use Illuminate\Support\Facades\Route;
use App\Http\Controllers\SecretController;

// Add auth middleware to the route below
Route::get('/secret', [SecretController::class, 'show']);

Need a hint?

Chain ->middleware('auth') to the route definition.

3

Create the SecretController with show method

Create a controller named SecretController in app/Http/Controllers with a public method show that returns the view secret.

Laravel

<?php

namespace App\Http\Controllers;

// Create SecretController class with show() method
// Your code here

Need a hint?

Define SecretController class extending Controller with a show method returning view('secret').

4

Create the Blade view to show the secret message

Create a Blade view file named secret.blade.php in the resources/views folder. Inside it, write the text This is a secret message for authenticated users only. inside a <div>.

Use a simple <div> tag with the exact text inside.
