JSON::RPC2 - Transport-independent implementation of json-rpc 2.0
This document describes JSON::RPC2 version 0.1.2
See JSON::RPC2::Server and JSON::RPC2::Client for usage examples.
This module implement json-rpc 2.0 protocol in transport-independent way. It was very surprising for me to find on CPAN a lot of transport-dependent implementations of (by nature) transport-independent protocol!
Also it support non-blocking client remote procedure call and both blocking and non-blocking server method execution. This can be very useful in case server methods will need to do some RPC or other slow things like network I/O, which can be done in parallel with executing other server methods in any event-based environment.
See JSON::RPC2::Server and JSON::RPC2::Client for details.
There a lot of other RPC modules on CPAN, most of them has features doesn't provided by this module, but they either too complex and bloated or lack some features I need.
Not transport-independent.
Not transport-independent. Do eval() of perl code received from remote server.
Not transport-independent. Not event-loop-independent.
Not transport-independent. Blocking on remote function call.
In theory it's doing everything... but I failed to find out how to use it (current version is 0.05) - probably it's incomplete yet. Even now it's too complex and bloated for me, I prefer small and simple solutions.
None.
JSON::RPC2 requires no configuration files or environment variables.
JSON::XS
None reported.
Not supported neither in Server nor in Client.
It may be cool to have parallel request processing allowed in spec using event-based style. But this feature doesn't looks really useful so it implementation delayed until it become clear it's needed to avoid needless complexity.
While it's ease to add support in Client, it's still not clear how to define methods with named parameters on Server - because perl has no native support for named parameters and there too many different and incompatible ways to add that support.
No bugs have been reported.
