NAME

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

VERSION

version 0.10

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.
