CORS Middleware in Dingo API in Laravel - php

Question

I want to apply cors in dingo api in laravel.
Because, I am getting this error.
No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://localhost:9000' is therefore not allowed access. The response had HTTP status code 500.
I have tried this.
Created Cors middleware.
Added like this Cors.php
<?php
namespace App\Http\Middleware;
use Closure;
class Cors
{
/**
* Handle an incoming request.
*
* #param \Illuminate\Http\Request $request
* #param \Closure $next
* #return mixed
*/
public function handle($request, Closure $next)
{
return $next($request)
->header('Access-Control-Allow-Origin', '*')
->header('Access-Control-Allow-Methods', 'GET, POST, PUT, DELETE, OPTIONS')
->header('Access-Control-Allow-Headers',' Origin, Content-Type, Accept, Authorization, X-Request-With')
->header('Access-Control-Allow-Credentials',' true');
}
}
Then modified Kernel.php like this.
protected $routeMiddleware = [
'auth' => \Illuminate\Auth\Middleware\Authenticate::class,
'auth.basic' => \Illuminate\Auth\Middleware\AuthenticateWithBasicAuth::class,
'bindings' => \Illuminate\Routing\Middleware\SubstituteBindings::class,
'can' => \Illuminate\Auth\Middleware\Authorize::class,
'guest' => \App\Http\Middleware\RedirectIfAuthenticated::class,
'throttle' => \Illuminate\Routing\Middleware\ThrottleRequests::class,
'cors' => \App\Http\Middleware\Cors::class,
];
Now, I want to know how to add middleware in dingo api routes.
Routes are like this.
$api->version('v1', function($api){
$api->GET('statelist', 'App\Http\Controllers\HospitalController#statelist');
});
$api->version('v1', function($api){
$api->GET('citylist', 'App\Http\Controllers\HospitalController#citylist');
});

Answer 1

try
$api->version('v1', function ($api) {
$api->group(['middleware' => 'cors'], function ($api) {
$api->GET('statelist', 'App\Http\Controllers\HospitalController#statelist');
$api->GET('citylist', 'App\Http\Controllers\HospitalController#citylist');
});
});
