Configuration

Quick Setup

1. Install the package:

   composer require larawizards/lara-oauth2-client

2. Publish configuration:

   php artisan lara-oauth2-client:install

3. Configure your .env file:

   OAUTH2_CLIENT_ID=your-client-id
   OAUTH2_CLIENT_SECRET=your-client-secret
   OAUTH2_REDIRECT_URI=http://your-app.com/oauth2/callback
   OAUTH2_AUTHORIZATION_URL=https://your-provider.com/oauth/authorize
   OAUTH2_TOKEN_URL=https://your-provider.com/oauth/token
   OAUTH2_USER_INFO_URL=https://your-provider.com/oauth/userinfo
   OAUTH2_SCOPES=openid profile email

4. Run migrations:

   php artisan migrate

Detailed Configuration

For complete configuration instructions, including:

• Step-by-step setup guide
• Configuration examples for popular providers (Google, Microsoft, GitHub, Auth0, Okta)
• Fortify/Jetstream integration setup
• Custom user mapping
• Advanced options

See CONFIGURATION.md for detailed instructions.

Usage

Basic Usage

The package automatically registers routes for OAuth2 authentication:

• GET /oauth2/redirect - Redirects to OAuth2 provider
• GET /oauth2/callback - Handles OAuth2 callback
• POST /oauth2/logout - Logout and optionally revoke tokens
• GET /login/sso - SSO login page (if enabled)

Using the SSO Login Page

Simply redirect users to the SSO login route:

return redirect()->route('login.sso');

Or use the OAuth2 redirect directly:

return redirect()->route('oauth2.redirect');

Protecting Routes with Middleware

Use the oauth2.auth middleware to protect routes:

Route::middleware(['oauth2.auth'])->group(function () {
    Route::get('/dashboard', function () {
        return view('dashboard');
    });
});

User Model Configuration

The package automatically maps OAuth2 user attributes to your user model. You can customize the mapping in config/lara-oauth2-client.php:

'user_mapping' => [
    'id' => 'oauth2_id',
    'email' => 'email',
    'name' => 'name',
    'first_name' => 'first_name',
    'last_name' => 'last_name',
    'avatar' => 'avatar',
],

Make sure your user model has the necessary columns. You may need to create a migration:

Schema::table('users', function (Blueprint $table) {
    $table->string('oauth2_id')->nullable()->unique();
    $table->string('avatar')->nullable();
});

Laravel Fortify Integration

1. Enable Fortify integration in your .env:

OAUTH2_FORTIFY_ENABLED=true

1. The package will automatically integrate with Fortify's login views.

Laravel Jetstream Integration

1. Enable Jetstream integration in your .env:

OAUTH2_JETSTREAM_ENABLED=true

1. Publish Jetstream views (if not already done):

php artisan jetstream:install livewire
# or
php artisan jetstream:install inertia

1. The package will add an SSO login button to your Jetstream login page.

Customizing Views

Publish the views to customize them:

php artisan vendor:publish --tag=lara-oauth2-client-views

Views will be published to resources/views/vendor/lara-oauth2-client/.

Programmatic Usage

You can also use the OAuth2 client directly:

use Larawizards\LaraOAuth2Client\OAuth2Client;

$client = app(OAuth2Client::class);

// Get authorization URL
$authUrl = $client->getAuthorizationUrl();

// Get access token (after receiving authorization code)
$tokenData = $client->getAccessToken($code, $state);

// Get user info
$userInfo = $client->getUserInfo($tokenData['access_token']);

// Refresh token
$newTokenData = $client->refreshAccessToken($refreshToken);

Configuration Options

All configuration options are available in config/lara-oauth2-client.php:

Testing

Run the test suite:

composer test

Or with PHPUnit:

vendor/bin/phpunit

For detailed testing instructions, see TESTING.md.

Security Best Practices

1. Always use HTTPS in production for OAuth2 redirects
2. Store client secrets securely - never commit them to version control
3. Use environment variables for all sensitive configuration
4. Enable CSRF protection - the package uses Laravel's built-in CSRF protection
5. Validate state parameters - the package automatically validates state to prevent CSRF attacks
6. Encrypt tokens - access and refresh tokens are automatically encrypted in the database

Requirements

• PHP >= 8.2
• Laravel >= 10.0
• Guzzle HTTP Client
