Modify Controller
open /app/Http/Controllers/JWTAuthController.php file in Laravel project folder and add below code.
public function refresh() {
return $this->respondWithToken(Auth::guard('api')->refresh());
}
Modify Route
open /routes/api.php file for the url which is to refresh jwt token, and add below code.
...
Route::group(['middleware' => 'auth:api'], function(){
...
Route::get('refresh', 'JWTAuthController@refresh')->name('api.jwt.refresh');
...
});

Test
let’s test jwt token refresh feature we’ve developed via Postman.
# URL
localhost/api/refresh
# header
Authorization
Bearer jwt_token
if jwt token is valid, jwt token is refreshed and issues new token like below screen.
if jwt token is expired or previous jwt token, you can get 401 error response.
