In this tutorial we will learn how to use JWT token in Laravel.
JSON Web Tokens (JWTs) are a popular way of securely transmitting information between parties as a JSON object. Laravel makes it easy to work with JWTs by providing a package called "tymon/jwt-auth" that handles the creation, signing, and verification of tokens.
How to use JWT token in Laravel
Here are the steps to use JWT tokens in Laravel:
Step 1 - Install the tymon/jwt-auth package via Composer:
composer require tymon/jwt-auth
Step 2 - Run the package's installation command:
php artisan jwt:secret
Step 3 - Update the `config/auth.php` file to use JWT as the default driver:
'defaults' => [
'guard' => 'api',
'passwords' => 'users',
],
'guards' => [
'api' => [
'driver' => 'jwt',
'provider' => 'users',
],
],
Step 4 - Create a new authentication controller using the make:auth command:
php artisan make:controller AuthController
Step 5 - Define a method for generating a JWT token in the AuthController:
use JWTAuth;
use Tymon\JWTAuth\Exceptions\JWTException;
public function authenticate(Request $request)
{
$credentials = $request->only('email', 'password');
try {
if (!$token = JWTAuth::attempt($credentials)) {
return response()->json(['error' => 'Invalid credentials'], 401);
}
} catch (JWTException $e) {
return response()->json(['error' => 'Could not create token'], 500);
}
return response()->json(compact('token'));
}
Step 6 - Protect your routes with the `jwt.auth` middleware:
Route::group(['middleware' => 'jwt.auth'], function () {
Route::get('protected', function () {
return response()->json(['foo' => 'bar']);
});
});
Step 7 - Send the JWT token with each request in the Authorization header:
Authorization: Bearer {your-token-here}
That's it! You can now use JWT tokens in your Laravel application.
