How to receive a redirect from mapForm and access the params on the body or header?

[Sérgio Paulo Gomes]

Hello everyone!

I have two applications.

One is opening my Angular application through a redirect request.

And I need to pass a param.

This is the way I'm doing:

```

  post(obj, url) {

        const mapForm = document.createElement('form');

        mapForm.target = '_blank';

        mapForm.method = 'POST';

        mapForm.action = url;

        Object.keys(obj).forEach(param => {

            const mapInput = document.createElement('input');

            mapInput.type = 'hidden';

            mapInput.id = param;

            mapInput.name = param;

            mapInput.setAttribute('value', obj[param]);

            mapForm.appendChild(mapInput);

        });

        document.body.appendChild(mapForm);

        mapForm.submit();

    }

```

But how can I receive this param on the Angular application?
