I'm trying to learn out Cro (and Perl6 simultaneously) ;)
My study app is based on the documentation of Cro. I added some authentication which does work, but the user session gets forgotten immediately.
You can check out the code at https://gitlab.com/ecocode/beaverapp go to the login pasge and login with "user" and "pwd". You get rerouted to / (which indicates the login succeeded), but the message there is "Current user: -". So the session gets lost.
The relevant part of Routes.pm6 :
class UserSession does Cro::HTTP::Auth {
has $.username is rw;
method logged-in() {
defined $!username;
}
}
my $routes = route {
subset LoggedIn of UserSession where *.logged-in;
get -> UserSession $s {
content 'text/html', "Current user: {$s.logged-in ?? $s.username !! '-'}";
}
get -> LoggedIn $user, 'users-only' {
content 'text/html', "Secret page just for *YOU*, $user.username()";
}
get -> 'login' {
content 'text/html', q:to/HTML/;
<form method="POST" action="/login">
<div>
Username: <input type="text" name="username" />
</div>
<div>
Password: <input type="password" name="password" />
</div>
<input type="submit" value="Log In" />
</form>
HTML
}
post -> UserSession $user, 'login' {
request-body -> (:$username, :$password, *%) {
if valid-user-pass($username, $password) {
$user.username = $username;
redirect '/', :see-other;
}
else {
content 'text/html', "Bad username/password";
}
}
}
sub valid-user-pass($username, $password) {
# Call a database or similar here
return $username eq 'user' && $password eq 'pwd';
}
}
sub routes(Beaverapp $beaverapp) is export {
route {
# Apply middleware, then delegate to the routes.
before Cro::HTTP::Session::InMemory[UserSession].new;
delegate <*> => $routes;
}
}
I think the problem is due to the middleware session management not working. How should I correct this? Or maybe the problem is due to something else?
