I am working on an API application that will be run in different domains: http://example.com/ , http://sub.example.com/ , http://example-another.com/ . Part of the API responses needs to send out its base_url . So I am trying to find a way to dynamically collect the base_url and add it to my response.
I have a factory to initiate the action handler as follows:
class TestHandlerFactory
{
public function __invoke(ContainerInterface $container) : TestHandler
{
return new TestHandler();
}
}
Then my action handler is as follows:
class TestHandler implements RequestHandlerInterface
{
public function __construct()
{
...
}
public function handle(ServerRequestInterface $request) : ResponseInterface
{
...
}
}
I am new to Zend world and I found the https://github.com/zendframework/zend-http/blob/master/src/PhpEnvironment/Request.php probably a potential solution of my problem. However, I do not how to get that PHP-Environment object (or any other object that help me grab the base url) in the factory or handler class.
zend-http is not used in expressive, it's for zend-mvc. In expressive PSR-7 HTTP message interfaces are used and by default this is handled in zend-diactoros .
class TestHandler implements RequestHandlerInterface
{
public function handle(ServerRequestInterface $request) : ResponseInterface
{
// Get request URI
$uri = $request->getUri();
// Reconstruct the part you need
$baseUrl = sprintf('%s://%s', $uri->getScheme(), $uri->getAuthority());
}
}
More info can be found here: https://github.com/zendframework/zend-diactoros/blob/master/src/Uri.php
EDIT: You cannot grab the request details in the factory itself. This can only be done in Middleware or Handlers (which are sort of a middleware).
