Oauth2-server-laravel custom message response - php

Question

I am using Oauth-server-laravel Authentication.
What i have done so far:
When i post wrong access_token to API that i have created in laravel it gives following response,
{
"error": "access_denied",
"error_description": "The resource owner or authorization server denied the request."
}
I have used oauth as middleware in route as follow,
Route::group(['namespace' => 'Modules\User\Http\Controllers', 'middleware' => 'oauth'], function () {
// Get User Profile Details
Route::post('getUserProfileDetail', 'UserController#getUserProfileDetail');
});
Problem:
If credentials are wrong then oauth automatically respond with it's default message and i want to customize that response messages,
I have half succeed in that if credentials are correct then it calls function that specifies in route and in that i am appending mre response that i want to send.
$response = $this->authorizer->issueAccessToken();
$code = 200; //Response OK
$response['result'] = 'success';
$response['user_id'] = $user['id'];
$response['email'] = $user['email'];
$response['name'] = $user['name'];
But i'm unable to send it when credentials are not correct because it can't call function and send it's default response to user.

I fall this types of problem to set custom message then this worked for me (a blog post I wrote about this article)]
So first create a middleware in app/Http/Middleware.My middleware name is OauthExceptionMiddleware
Then open
app/Http/kernel.php
and put this middleware instead of oauth2 previous middleware in $middleware array,like this
protected $middleware = [
\Illuminate\Foundation\Http\Middleware\CheckForMaintenanceMode::class,
\App\Http\Middleware\OauthExceptionMiddleware::class,
];
Oauth2 Custom Exception Error Message
<?php
/**

* User: kingpabel
* Date: 3/23/16
* Time: 4:40 PM
*/
namespace app\Http\Middleware;
use Closure;
use League\OAuth2\Server\Exception\OAuthException;
class OauthExceptionMiddleware
{
public function handle($request, Closure $next)
{
try {
$response = $next($request);
// Was an exception thrown? If so and available catch in our middleware
if (isset($response->exception) && $response->exception) {
throw $response->exception;
}
return $response;
} catch (OAuthException $e) {
$data = [
// 'error' => $e->errorType,
// 'error_description' => $e->getMessage(),
'error' => 'Custom Error',
'error_description' => 'Custom Description',
];
return \Response::json($data, $e->httpStatusCode, $e->getHttpHeaders());
}
}
}
