In web applications, OAuth2 authentication has become a popular standard, allowing users to use an authorization server to enable third-party applications to access and operate their protected resources. ThinkPHP6 is a fast and modern PHP framework suitable for all types of applications. It provides easy-to-use and powerful tools to implement OAuth2 authentication. In this article, we will explore how to implement OAuth2 authentication using ThinkPHP6.
Step 1: Install ThinkPHP6
To start using ThinkPHP6, you must first install Composer in your local environment. Open a terminal or command line window in your project directory and execute the following command:
composer create-project topthink/think oauth2
This will create a new directory called oauth2 in your project directory and install all necessary ThinkPHP6 components.
Step 2: Install PHP-JWT
ThinkPHP6 OAuth2 authentication relies on PHP-JWT, which is a PHP library for generating and validating JSON Web Token (JWT). Before that, we should install the PHP-JWT library first. In a terminal or command line window, execute the following command:
composer require firebase/php-jwt
Step 3: Create an OAuth2 service provider
The OAuth2 service provider allows third-party applications to access protected areas through authorization H. In ThinkPHP6, the OAuth2 service provider is implemented based on the abstract class thinkoauthproviderAbstractProvider. We need to create an OAuth2 service provider and implement the following methods:
The following is a simple OAuth2 service provider example:
<?php namespace appoauthprovider; use FirebaseJWTJWT; use thinkoauthproviderAbstractProvider; class SampleProvider extends AbstractProvider { public function getClientId(): string { return 'YOUR_CLIENT_ID'; } public function getClientSecret(): string { return 'YOUR_CLIENT_SECRET'; } public function getAuthorizationUrl(): string { $authUrl = 'https://your.auth.server/auth?' . 'client_id=' . $this->getClientId() . '&redirect_uri=' . urlencode($this->getRedirectUri()) . '&response_type=code'; return $authUrl; } public function validateAuthorizationCode(string $code): ?array { $payload = JWT::decode($code, $this->getClientSecret(), array('HS256')); // Check if payload is valid return $payload; } public function refreshToken(string $refreshToken): ?array { // Implement refresh token logic return null; } }
Step 4: Implement OAuth2 authentication middleware
Now, we need to implement OAuth2 authentication middleware in the application. In ThinkPHP6, middleware is implemented based on the abstract classes thinkmiddlewareMiddleware and thinksessionSessionManager. We need to create middleware and implement the following method:
The following is a simple OAuth2 authentication Middleware example:
<?php namespace appmiddleware; use appoauthproviderSampleProvider; use FirebaseJWTJWT; class OAuth2Middleware { public function handle( hinkRequest $request, Closure $next) { $provider = new SampleProvider(); // Check if access token exists $accessToken = $request->header('Authorization'); if (!$accessToken) { // Redirect to auth server $authUrl = $provider->getAuthorizationUrl(); return redirect($authUrl); } // Verify access token $jwtSecret = $provider->getClientSecret(); $verify = JWT::decode($accessToken, $jwtSecret, array('HS256')); // Check if token is valid if (!$verify) { return json(array( 'error' => 'Invalid token', )); } // Set user in session $session = hinkacadeSession::get('user'); $session['id'] = $verify['id']; hinkacadeSession::set('user', $session); // Go to next middleware return $next($request); } }
The above middleware implementation logic is as follows:
Step 5: Register OAuth2 authentication middleware
Now, we need to register the OAuth2 authentication middleware as global middleware in the application. In the configmiddleware.php file, add the following code:
<?php return [ 'oauth2' => ppmiddlewareOAuth2Middleware::class, ];
Now, we have completed all the steps to implement OAuth2 authentication using ThinkPHP6. You can use OAuth2 authentication middleware in your application to protect routes or controller actions that require access to authorized resources. With OAuth2 authentication middleware, you can use a token-based authorization mechanism to protect user data and sensitive API endpoints. Take advantage of the ease of use and powerful performance provided by ThinkPHP6 to develop a secure, high-performance web application.
