hello!
i'm wondering how one would implement the server side controller
end of an application with ajax. i have the javascript on my
client sending an xml file to a uri controller method but, how does
the controller process that xml? is the standard way of doing this
by reading in the xml file through stdin? i'd like to implement
this without using JSON of jemplate.
Ajax works behind the scenes like any CGI-ish interaction. Your
question is a bit vague so the sample code is too, but you could do
something like this-
use XML::LibXML;
sub ajax_widget : Public {
my ( $self, $c, $skin ) = @_;
my $parser = XML::LibXML->new();
# get it out of a XHR POST; badly formed or missing XML will
cause an error
my $doc = $parser->parse_string($c->request->body_params->
{xml_sent_by_js});
# use $doc and its contents however you like
$c->forward("View::YourAjaxView"); # return whatever your JS
expects
}
JSON is generally easier to work with, so I say, if you have a choice
going forward.
