Good afternoon all
I am busy with a project where I need to read an RFID tag, get the
data
associated with the tag and then push the data to a web page for a
security person to monitor.
I can successfully read the tag by using LogicAlloy's ALE server. It
then calls my Catalyst application at http://localhost/ale/notifier :
sub notifier : Private {
my ( $self, $c ) = @_;
#$c->stash->{template} = 'notifier.tt2';
$c->stash->{tagdata} = $c->request->params->{tagdata};
open (TagData, '>C:\Eclipse Projects\Asset
Tracker\AssetTracker\lib\AssetTracker\tagdata.txt');
print TagData $c->request->params->{tagdata};
close TagData;
}
As you can see I do not get the associated tag data yet, I am just
trying to display the tag data received from the ALE server.
I can see that the data is coming through correctly by monitoring the
console debug and checking the tagdata.txt file.
The problem that I have is that I have no idea how to push the data
to a
web page instead of pulling.
Hi,
you might want to have a look at http://meteorserver.org/. This server
pushes data to a client via a persistent http connection. To handle
such things with catalyst is not a very good idea. the ALE server will
talk to the meteor server and not the catalyst application.
If you do not need realtime push you could reload a catalyst page
every x seconds.
This page opens the file tagdata.txt and prints its content. Add a
html meta tag to reload the page every x seconds.
