json_pp - JSON::PP command utility SYNOPSIS
json_pp [-v] [-f from_format] [-t to_format] [-json_opt options_to_json] DESCRIPTION
json_pp converts between some input and output formats (one of them is JSON). This program was copied from json_xs and modified. The default input format is json and the default output format is json with pretty option. OPTIONS
-f -f from_format Reads a data in the given format from STDIN. Format types: json as JSON eval as Perl code -t Writes a data in the given format to STDOUT. null no action. json as JSON dumper as Data::Dumper -json_opt options to JSON::PP Acceptable options are: ascii latin1 utf8 pretty indent space_before space_after relaxed canonical allow_nonref allow_singlequote allow_barekey allow_bignum loose escape_slash -v Verbose option, but currently no action in fact. -V Prints version and exits. EXAMPLES
$ perl -e'print q|{"foo":"XX","bar":1234567890000000000000000}|' | json_pp -f json -t dumper -json_opt pretty,utf8,allow_bignum $VAR1 = { 'bar' => bless( { 'value' => [ '0000000', '0000000', '5678900', '1234' ], 'sign' => '+' }, 'Math::BigInt' ), 'foo' => "x{3042}x{3044}" }; $ perl -e'print q|{"foo":"XX","bar":1234567890000000000000000}|' | json_pp -f json -t dumper -json_opt pretty $VAR1 = { 'bar' => '1234567890000000000000000', 'foo' => "x{e3}x{81}x{82}x{e3}x{81}x{84}" }; SEE ALSO

JSON::RPC::Client(3pm) User Contributed Perl Documentation JSON::RPC::Client(3pm) NAME
JSON::RPC::Client - Perl implementation of JSON-RPC client SYNOPSIS
use JSON::RPC::Client; my $client = new JSON::RPC::Client; my $url = 'http://www.example.com/jsonrpc/API'; my $callobj = { method => 'sum', params => [ 17, 25 ], # ex.) params => { a => 20, b => 10 } for JSON-RPC v1.1 }; my $res = $client->call($uri, $callobj); if($res) { if ($res->is_error) { print "Error : ", $res->error_message; } else { print $res->result; } } else { print $client->status_line; } # Easy access $client->prepare($uri, ['sum', 'echo']); print $client->sum(10, 23); DESCRIPTION
This is JSON-RPC Client. See <http://json-rpc.org/wd/JSON-RPC-1-1-WD-20060807.html>. Gets a perl object and convert to a JSON request data. Sends the request to a server. Gets a response returned by the server. Converts the JSON response data to the perl object. JSON
::RPC::Client METHODS $client = JSON::RPC::Client->new Creates new JSON::RPC::Client object. $response = $client->call($uri, $procedure_object) Calls to $uri with $procedure_object. The request method is usually "POST". If $uri has query string, method is "GET". About 'GET' method, see to <http://json-rpc.org/wd/JSON-RPC-1-1-WD-20060807.html#GetProcedureCall>. Return value is "JSON::RPC::ReturnObject". $client->prepare($uri, $arrayref_of_procedure) Allow to call methods in contents of $arrayref_of_procedure. Then you can call the prepared methods with an array reference or a list. The return value is a result part of JSON::RPC::ReturnObject. $client->prepare($uri, ['sum', 'echo']); $res = $client->echo('foobar'); # $res is 'foobar'. $res = $client->sum(10, 20); # sum up $res = $client->sum( [10, 20] ); # same as above If you call a method which is not prepared, it will "croak". Currently, can't call any method names as same as built-in methods. version Sets the JSON-RPC protocol version. 1.1 by default. id Sets a request identifier. In JSON-RPC 1.1, it is optoinal. If you set "version" 1.0 and don't set id, the module sets 'JSON::RPC::Client' to it. ua Setter/getter to LWP::UserAgent object. json Setter/getter to the JSON coder object. Default is JSON, likes this: $self->json( JSON->new->allow_nonref->utf8 ); $json = $self->json; This object serializes/deserializes JSON data. By default, returned JSON data assumes UTF-8 encoded. status_line Returns status code; After "call" a remote procedure, the status code is set. create_json_coder (Class method) Returns a JSON de/encoder in "new". You can override it to use your favorite JSON de/encoder. JSON
::RPC::ReturnObject "call" method or the methods set by "prepared" returns this object. (The returned JSON data is decoded by the JSON coder object which was passed by the client object.) METHODS is_success If the call is successful, returns a true, otherwise a false. is_error If the call is not successful, returns a true, otherwise a false. error_message If the response contains an error message, returns it. result Returns the result part of a data structure returned by the called server. content Returns the whole data structure returned by the called server. jsontext Returns the row JSON data. version Returns the version of this response data. JSON
::RPC::ServiceObject RESERVED PROCEDURE
When a client call a procedure (method) name 'system.foobar', JSON::RPC::Server look up MyApp::system::foobar. <http://json-rpc.org/wd/JSON-RPC-1-1-WD-20060807.html#ProcedureCall> <http://json-rpc.org/wd/JSON-RPC-1-1-WD-20060807.html#ServiceDescription> There is JSON::RPC::Server::system::describe for default response of 'system.describe'.
