I built an API with Lumen and want to access it with JavaScript and the XMLHttpRequest object. But every time my PUT, GET, POST, and DELETE requests are transformed into OPTIONS - Request. I read a lot of websites with information of CORS. I build middleware with the following content:
class CORSMiddleware
{
public function handle($request, \Closure $next)
{
$response = null;
/* Preflight handle */
if ($request->isMethod('OPTIONS')) {
$response = new Response();
} else {
$response = $next($request);
}
$response->header('Access-Control-Allow-Methods', 'OPTIONS, HEAD, GET, POST, PUT, DELETE');
$response->header('Access-Control-Allow-Headers', $request->header('Access-Control-Request-Headers'));
$response->header('Access-Control-Allow-Origin', '*');
return $response;
}
}
My client code:
var url = "http://localhost:8000/api/user";
var xmlHttpRequest = new XMLHttpRequest();
xmlHttpRequest.open('PUT', url, false);
xmlHttpRequest.send('{"username": "ABC", "password": "ABC","email": "[email protected]" }');
if (xmlHttpRequest.status == 200) {
console.log(xmlHttpRequest.responseText);
}
My request-information of GET request:

In the preflight there are no "Access-Control-Allow-*"-Headers. I don't know why; I enabled it with my lumen-cors-middleware.
Answer
Add following headers into public/.htaccess file.
Header set Access-Control-Allow-Origin "*"
Header set Access-Control-Allow-Methods "GET,POST,PUT,DELETE,OPTIONS"
Header set Access-Control-Allow-Credentials "true"
this is working fine for to resolve Cross Origin Issue.
