I want to make non-blocking requests to API via Mojo::UserAgent and allow
to render result of request without waiting result of previous request.
Code of working with API made in separate module (listing below). How to
convert code to non-blocking way?
*$cat Test.pm*
...
my $ua = Mojo::UserAgent->new;
sub api_func1 {
return $ua->get($api_url => form => \%hash)->res->body;
}
...
*$cat myapp.pl*
...
get '/r' => sub {
my $c = shift;
$c->render(json => api_func1());
}
...
I rewrote it to non-blocking way:
*$cat Test.pm*
sub api_func1 {
my $cb = shift;
$ua->get($api_url => form => \%hash => sub {
my ($ua, $tx) = @_;
*$cb**($tx->res->json);*
});
Mojo::IOLoop->start unless Mojo::IOLoop->is_running;
};
*$cat myapp.pl*
get '/r' => sub {
my $c = shift;
api_func1(sub => {
my ($self, $json) = @_;
$c->render(json => $json);
})
But I got a syntax error at string marked orange. What is wrong?
