DESCRIPTION

Parses its JSON data.

Passes the server object and the object decoded from the JSON data to your procedure (method).

Takes your returned value (scalar or arrayref or hashref).

Sends a response.

Well, you write your procedure code only.

METHODS

new

Creates new JSON::RPC::Legacy::Server object.

dispatch($package)

dispatch([$package1, $package1, ...])

dispatch({$path => $package, ...})

Sets your procedure module using package name list or arrayref or hashref. Hashref version is used for path_info access.

dispatch_to

An alias to "dispatch".

handle

Runs server object and returns a response.

raise_error(%hash)

 return $server->raise_error(
    code => 501,
    message => "This is error in my procedure."
 );
    

Sets an error. An error code number in your procedure is an integer between 501 and 899.

json

Setter/Getter to json encoder/decoder object. The default value is JSON object in the below way:

 JSON->new->utf8
    

In your procedure, changes its behaviour.

 $server->json->utf8(0);
    

The JSON coder creating method is "create_json_coder".

version

Setter/Getter to JSON-RPC protocol version used by a client. If version is 1.1, returns 1.1. Otherwise returns 0.

charset

Setter/Getter to charset. Default is 'UTF-8'.

content_type

Setter/Getter to content type. Default is 'application/json'.

return_die_message

When your program dies in your procedure, sends a return object with error message 'Procedure error' by default.

If this option is set, uses "die" message.

 sub your_procedure {
     my ($s) = @_;
    $s->return_die_message(1);
    die "This is test.";
 }
    

retrieve_json_from_post

It is used by JSON::RPC::Legacy::Server subclass.

retrieve_json_from_get

In the protocol v1.1, 'GET' request method is also allowable.

It is used by JSON::RPC::Legacy::Server subclass.

response

It is used by JSON::RPC::Legacy::Server subclass.

request

Returns HTTP::Request object.

path_info

Returns PATH_INFO.

max_length

Returns max content-length to your application.

translate_error_message

Implemented in your subclass. Three arguments (server object, error code and error message) are passed. It must return a message.

 sub translate_error_message {
     my ($s, $code, $message) = @_;
     return $translation_jp_message{$code};
 }
    

create_json_coder

(Class method) Returns a JSON de/encoder in "new". You can override it to use your favorite JSON de/encode.
