How to get baseUrl in ZF2 controller?

Question

In my zf2 controller I want to retrieve the application base URL (for example http://example.com).

I tried the following call but it returns an empty string.

$this->request->getBasePath();

How can I then get the http://example.com part of URL in my controller?

I know this is not the prettiest way of doing it but, hey, it works:

public function indexAction()
{
    $uri = $this->getRequest()->getUri();
    $scheme = $uri->getScheme();
    $host = $uri->getHost();
    $base = sprintf('%s://%s', $scheme, $host);

    // $base would be http://example.com
}

Or if you don't mind shortening everything you could do it in two lines:

public function indexAction()
{
    $uri = $this->getRequest()->getUri();
    $base = sprintf('%s://%s', $uri->getScheme(), $uri->getHost());
}
