Repository

Development Environment
in here, we’ll use Laravel development environment created by Laradock and Ansible. if you want to know our environment, see our previous blog.
Modify Controller
open /app/Http/Controllers/JWTAuthController.php controller file in Laravel project folder, and add below code.
public function logout() {
Auth::guard('api')->logout();
return response()->json([
'status' => 'success',
'message' => 'logout'
], 200);
}
Modify Route
open /routes/api.php file, and add below code for the url which is for logout.
...
Route::group(['middleware' => 'auth:api'], function(){
...
Route::get('logout', 'JWTAuthController@logout')->name('api.jwt.logout');
...
});
...
Test
let’s check logout feature via Postman.
# URL
localhost/api/logout
# header
Authorization
Bearer jwt_token
if jwt token is valid, you can successfully logout.
if jwt token is expired or previous jwt token, you can get 401 error response.
Completed
we’ve implemented a token based authentication system by adding jwt authentication system to Laravel project. we will use this jwt authentication system to develop RN(React Native) app.
