I'm working on a suite of HTTP/REST JSON web services, but running into a
little strangeness. I figured I'm probably just not doing this right, so
I'm posting here for clarification.
I am encoding LDAP attribute:value pairs to a hash, then encoding the hash
to JSON. However, when I pass this encoded JSON to the render method of
M::Controller, I get some strange escaping unless I specify it as 'data'.
Encoding data pulled from the Net::LDAP::Entry object:
@attrs = $entry->attributes;
foreach my $attr(@attrs) { $value = $entry->get_value($attr);
$output{$attr} = $value;}
$json_output = $json->encode(\%output);
When I print out $json_output, everything is nicely encoded as I expect. It
is when I try to render the response that I run into trouble unless I
specify the 'data' directive.
So the following snippet:
return $c->render( data => $json_output, status => 200) gives me
{"someattribute":"somevalue"}
as expected.
but:
return $c->render( json => $json_output, status => 200) gives me
"{\"someattribute\":\"somevalue\"}"
which I didn't expect.
I would love to be able to pass an unencoded hash into the 'json' method
like so:
return $c->render( json => %output, status => 200)
or pass by reference:
return $c->render( json => \%output, status => 200)
but these exhibit the same behavior.
1.) What is causing this escaping behavior? I suspect it's something like
I'm completely misunderstanding the 'json' directive to the render method.
2.) Is there a better way to pass a hash so that it is automatically
encoded?
Any finger pointing in the appropriate direction is greatly appreciated.
