TRANSITION PLAN

In the next large update version, JSON and JSONRPC modules are split.

  JSONRPC* and Apache::JSONRPC are deleted from JSON dist.
  JSONRPC::Client, JSONRPC::Server and JSONRPC::Procedure in JSON::RPC dist.

  Modules in JSON::RPC dist supports JSONRPC protocol v1.1 and 1.0.

DESCRIPTION

This module is JSONRPC subclass. Most ideas were borrowed from the XMLRPC::Lite manpage. Currently JSONRPC provides only CGI server function.

CHARSET

When the module returns response, its charset is UTF-8 by default. You can change it via passing a key/value pair into handle().

 my %charset = (charset => 'EUC-JP');
 JSONRPC::Transport::HTTP::CGI->dispatch_to('MyApp')->handle(%charset);

QUERY OBJECT

If you want to use any other query object instead of CGI for JSONRPC::Transport::HTTP::CGI, you can pass query option and paramName.

 my %opt = (
   query     => $session, # CGI::Session object
   paramName => 'json',
 );

 JSONRPC::Transport::HTTP::CGI->dispatch_to('MyApp')->handle(%opt);

CAUTION

JSONRPC::Transport::HTTP::CGI requires CGI.pm which version is more than 2.9.2. (the core module in Perl 5.8.1.)

Since verion 1.0, JSONRPC::Transport::HTTP requires the HTTP::Request manpage and the HTTP::Response manpage. For using JSONRPC::Transport::HTTP::Client, you need the LWP::UserAgent manpage.
