CORS policy

Hello!

Try using vue js pass in the backend:

...
axios.post('https://mysite.ru', dataSend, {
    headers: {
        'Content-Type': 'application/json',
        Accept: 'application/json'
    }
})
...

Phalcon:

...
$app->response
    ->setHeader("Access-Control-Allow-Origin", '*')
    ->setHeader("Access-Control-Allow-Methods", 'GET,PUT,POST,DELETE,OPTIONS')
    ->setHeader("Access-Control-Allow-Headers", '*')
    ->setHeader("Access-Control-Allow-Credentials", true)
    ->send();
...

I get the error:

Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' header is present on the requested resource.

unless the request to remove the content-type is no error. what is the problem?
