The central template rendering magic needs an overhaul: Currently, LoginProviderInterface has to be implemented, which retrieves a "prepared" view with tons of variable used by the default Layout "Login.html". Single LoginProviderInterface then set their template path ("Login/UserPassLoginForm" in UsernamePasswordLoginProvider), which sets Login.html as layout in its template to then get its sections "loginFormFields" and "ResetPassword" rendered. This strategy is a major mess and needs to be turned around somehow. Note there is also this BE "relogin" and "login refresh" foo with lots of attached JS magic that should either be streamlined to actually work, or (preferred) be thrown away.

Injects the request and response objects for the current request or subrequest As this controller goes only through the main() method, it is rather simple for now
refreshAction()  : ResponseInterface
Calls the main function but with loginRefresh enabled at any time
requestTokenAction()  : ResponseInterface
Returns a new request-token value, which is signed by a new nonce value (the nonce is sent as cookie automatically in `RequestTokenMiddleware` since it is created via the `NoncePool`).
appendLoginProviderCookie()  : ResponseInterface
If a login provider was chosen in the previous request, which is not the default provider, it is stored in a Cookie and appended to the HTTP Response.

Gets news as array from sys_news and converts them into a format suitable for showing them at the login screen.

Returns the uri of a relative reference, resolves the "EXT:" prefix (way of referring to files inside extensions) and checks that the file is inside the project root of the TYPO3 installation

public refreshAction(ServerRequestInterface $request) : ResponseInterface
Parameters
$request : ServerRequestInterface
Return values
ResponseInterface

requestTokenAction()

Returns a new request-token value, which is signed by a new nonce value (the nonce is sent as cookie automatically in `RequestTokenMiddleware` since it is created via the `NoncePool`).

public requestTokenAction(ServerRequestInterface $request) : ResponseInterface
Parameters
$request : ServerRequestInterface
Return values
ResponseInterface

appendLoginProviderCookie()

$response : ResponseInterface
Return values
ResponseInterface

createLoginLogout()

protected createLoginLogout(ServerRequestInterface $request, bool $loginRefresh) : ResponseInterface
Parameters
