jsonrpc

A Ruby implementation of JSON-RPC 2.0. It's as simple as a parser and a response builder.

Installation

Add this line to your application's Gemfile:

gem 'jsonrpc', git: 'https://github.com/codingstones/jsonrpc'

And then execute:

$ bundle

(We'll publish the gem to RubyGems soon).

Usage

How to build a JSON-RPC request:

require 'jsonrpc'

# First, we need a json with valid JSON-RPC format
p = {
    jsonrpc: '2.0',
    params: [1, 2],
    method: 'sum',
    id: 'foo'
}
request_body = JSON.generate(p)


# Let's parse it!
parser = JsonRPC::Parser.new
request = parser.parse(request_body)
request.invalid?  # false (validates the JSON-RPC format)
request.version   # 2.0
request.params    # [1, 2]
request.id        # 'foo'
request.method    # 'sum'

How to build a JSON-RPC response:

response = JsonRPC::Response.new(request_id: 'foo', result: 3)
response.to_json # {:jsonrpc=>"2.0", :id=>"foo", :result=>3}
