NAME

JSON::RPC::Common::Marshal::HTTP - Convert HTTP::Request and HTTP::Response to/from JSON::RPC::Common calls and returns.

VERSION

version 0.11

SYNOPSIS

        use JSON::RPC::Common::Marshal::HTTP;
        my $m = JSON::RPC::Common::Marshal::HTTP->new;
        my $call = $m->request_to_call($http_request);
        my $res = $call->call($object);
        my $http_response = $m->result_to_response($res);

DESCRIPTION

This object provides marshalling routines to convert calls and returns to and from HTTP::Request and HTTP::Response objects.

ATTRIBUTES

prefer_get

When encoding a call into a request, prefer GET.

Not reccomended.

rest_style_methods

When encoding a GET request, use REST style URI formatting (the method is part of the path, not a parameter).

prefer_encoded_get

When set and a "params" param exists, decode it as Base 64 encoded JSON and use that as the parameters instead of the query parameters.

See <http://json-rpc.googlegroups.com/web/json-rpc-over-http.html>.

user_agent

Defaults to the marshal object's class name and the JSON::RPC::Common version number.

content_type

accept_content_type

content_types

accept_content_types

When explicitly set these are the values of the "Content-Type" and "Accept" headers to set.

Otherwise they will default to "application/json" with calls/returns version 1.0 and 1.1, and "application/json-rpc" with 2.0 objects.

expand

Whether or not to use an expander on "GET" style calls.

expander

An instance of CGI::Expand or a look alike to use for "GET" parameter expansion.

METHODS

request_to_call $http_request

post_request_to_call $http_request

get_request_to_call $http_request

Convert an HTTP::Request to a JSON::RPC::Common::Procedure::Call. Depending on what style of request it is, "request_to_call" will delegate to a variant method.

Get requests call "uri_to_call"

uri_to_call $uri

encoded_uri_to_call $uri

query_uri_to_call $uri

Parse a call from a GET request's URI.

result_to_response $return

Convert a JSON::RPC::Common::Procedure::Return to an HTTP::Response.

write_result_to_response $result, $response

Write the result into an object like Catalyst::Response.

response_to_result $http_response

response_to_result_success $http_response

response_to_result_error $http_response

Convert an HTTP::Response to a JSON::RPC::Common::Procedure::Return.

A variant is chosen based on "HTTP::Response/is_success".

The error handler will ensure that "error" in JSON::RPC::Common::Procedure::Return is set.

call_to_request $call, %args

call_to_get_request $call, %args

call_to_post_request $call, %args

call_to_uri $call, %args

call_to_encoded_uri $call, %args

call_to_query_uri $call, %args

Convert a call to a request (or just a URI for GET requests).

The arguments can contain a "uri" parameter, which is the base of the request.

With GET requests, under "rest_style_methods" that URI's path will be appended, and otherwise parameters will just be added.

POST requests do not cloen and alter the URI.

If no URI is provided as an argument, "/" will be used.

The flags "prefer_get" and "encoded" can also be passed to "call_to_request" to alter the type of request to be generated.

collapse_query_params

expand_query_params

Only used for query encoded GET requests. If "expand" is set will cause expansion of the params. Otherwise it's a noop.

Subclass and override to process query params into RPC params as necessary.

Note that this is NOT in any of the JSON-RPC specs.
