Implement PHP security verification using Laravel Fortify

Use Laravel Fortify to implement PHP security verification

Introduction:
With the widespread application of the Internet, network security issues have become increasingly prominent. Keeping user information secure is a critical task when building and developing web applications. In order to strengthen PHP security verification, we can use Laravel Fortify, a powerful tool to simplify and strengthen our verification process. This article will introduce the basic concepts and usage of Laravel Fortify, and provide some example code to help readers better understand.

1. Laravel Fortify Introduction
   Laravel Fortify is an officially provided PHP package that provides a modern authentication system for the Laravel framework. Fortify provides a series of pre-built authentication functions, including registration, login, password reset, email verification, etc., which can help us quickly build safe and reliable user authentication functions. At the same time, Fortify also integrates some other features, such as two-step verification, limiting the number of login attempts, etc., to provide more comprehensive security.
2. Installing Laravel Fortify
   First, make sure you have installed the Laravel framework. Then, switch to your project directory in the terminal and execute the following command to install Laravel Fortify:

composer require laravel/fortify

After the installation is complete, we need to run the following command to generate the Fortify configuration file:

php artisan vendor:publish --provider="LaravelFortifyFortifyServiceProvider"

configuration file will be generated under config/fortify.php, where we can make some custom configurations.

3. Basic usage
   After the configuration is completed, we can start using Laravel Fortify. First, introduce some basic configuration and routing of Fortify into your application:

// routes/web.php

use LaravelFortifyFortify;

// 引入 Fortify 的一些基本配置
Fortify::loginView(function () {
    return view('auth.login');
});

// 引入 Fortify 的路由
Fortify::authenticateUsing(function (Request $request) {
    // 用户验证逻辑
});

// 用户认证相关路由
Route::group(['middleware' => config('fortify.middleware', ['web'])], function () {
    // 注册、登录、密码重置、邮箱验证等路由
    Fortify::registerRoutes();
    Fortify::resetPasswordRoutes();
    Fortify::verifyEmailRoutes();
});

The basic configuration here includes the view of the user login interface and user authentication logic. Fortify provides some preset view templates that you can modify or customize according to your needs.

4. Custom user authentication logic
   In the above sample code, we mentioned the user authentication logic part. Here, we can customize the user's authentication method by implementing Laravel Fortify's authenticateUsing method. The following is a simple example:

// routes/web.php

use LaravelFortifyFortify;
use IlluminateSupportFacadesAuth;

Fortify::authenticateUsing(function (Request $request) {
    // 获取表单提交的登录信息
    $credentials = $request->only('email', 'password');

    // 用户认证逻辑
    if (Auth::attempt($credentials)) {
        return redirect()->intended('/dashboard');
    } else {
        return back()->withErrors([
            'email' => 'Email 或密码不正确',
        ]);
    }
});

In this example, we use Laravel's Auth Facade for user authentication. You can use different user authentication methods based on your application needs.

5. Other features
   In addition to basic authentication functions, Laravel Fortify also provides some other security features. These features can be configured in the config/fortify.php file. Here are some examples of commonly used features:

• Two-step verification: Use Laravel’s TwoFactorAuthentication middleware to enable two-step verification:

  Fortify::authenticateThrough(function (Request $request) {
    return array_filter([
        config('fortify.limiters.login') ? null : RateLimiter::for('login'),
        $request->input('remember') ? null : ThrottleFailedLogins::forUser($request->user()),
        TwoFactorAuthentication::check($request) ? null : PreventsTwoFactorAuthentication::class,
    ]);
  });

  Copy after login

• Limit the number of login attempts: The number of login attempts and lock time can be configured in config/fortify.php:

  'limiters' => [
    'login' => [
        'enabled' => true,
        'tries' => 5,
        'lockout_time' => 300,
    ],
  ],

  Copy after login
• Email verification: Provided by Fortify There is a set of pre-built routes to handle email verification related logic, which you can configure in config/fortify.php.

Conclusion:
By using Laravel Fortify, we can easily build and strengthen our PHP security verification process. This article introduces the basic concepts and usage of Laravel Fortify, and provides some example code to help readers better understand. Hopefully this information will help you better protect the security of your users' information and increase the trustworthiness and reliability of your web applications.
