LWP::UserAgent::JSON - a subclass of LWP::UserAgent that understands JSON
my $user_agent = LWP::UserAgent::JSON->new; my $request = HTTP::Request::JSON->new(...); my $response = $user_agent->request($request); # $response->isa('HTTP::Response::JSON') if we got back JSON
This is a subclass of LWP::UserAgent which recognises if it gets JSON output back, and if so returns an HTTP::Response::JSON object instead of a HTTP::Response object. It exposes the logic of reblessing the HTTP::Response object in case you get handed a HTTP::Response object by some other method.
It also offers a handful of convenience methods to directly convert parameters into JSON for POST, PUT and PATCH requests.
Like LWP::UserAgent::post, except for when it's called as
post_json($url, $form_ref, ...), in which case $form_ref is turned into JSON. Obviously if you specify Content-Type or Content in subsequent header arguments they'll take precedence.
A variant on LWP::UserAgent::put with the same transformations as post_json. This requires that your version of LWP supports PUT, i.e. you have LWP 6.00 or later.
As post_json and put_json, but generates a PATCH request instead. As put_json, you need a semi-modern version of LWP for this.
LWP::UserAgent doesn't actually implement a patch method, so it's defined here.
In: $object Out: $reblessed
Supplied with a HTTP::Request or HTTP::Response object, looks to see if it's a JSON object, and if so reblesses it to be a HTTP::Request::JSON or HTTP::Response::JSON object respectively. Returns whether it reblessed the object or not.
