I was fighting Sinatra in order to make it an xmlrpc server. The big problem is that the xmlrpc library that arrive with Ruby -> well it sucks big time.
The client actually really nice, but the server really sucks. So, I started fighting the XMLRPC, and Sinatra did not like some of my work, and did not want to go to stage to perform, and I needed to talk with it's manager 🙂
At the end I found out why Sinatra and XMLRPC server does not like each other, and I was able to make Sinatra work with XMLRPC server at the end. The problem of course is the XMLRPC, and Sinatra actually a fine singer (so take off the Mafia from me now ok ?).
So how we can make Sinatra find dity and perform with XMLRPC as a server ?
Here is a Proof of concept for working with the two of them (writing it without testing the PoC):
#!/usr/bin/env ruby require 'rubygems' require 'sinatra' require 'uri' require 'xmlrpc/server' require 'xmlrpc/marshal' require 'xmlrpc/parser' require 'xmlrpc/create' require 'xmlrpc/config' require 'xmlrpc/utils' module MyModule class Application < Sinatra::Base def initialize(app=nil) super # we are inheriting stuff from older constructor ... # fill in the missing stuff you need for your app @rpc = XMLRPC::CGIServer.new # We are using general server rather then actual server # The line bellow is a MUST for make it work properly, add some dummy call # or if we have only one call, it will also work for us @rpc.set_default_handler do | dummy | dummy end # @rpc.set_default_handler do | dummy | # <?xml version="1.0"?> # <methodCall> # <methodName>ngx1.call_init</methodName> # <params> # <param> # <value> # <struct> # <member> # <name>x</name> # <value><int>10</int></value> # </member> # <member> # <name>y</name> # <value><int>10</int></value> # </member> # </struct> # </value> # </param> # </params> # </methodCall> @rpc.add_handler('sum') do | x, y | # names of params must be equal to the rpc names x + y # sending the result as xmlrpc end # @rpc.add_handler('sum') end # initialize(app=nil) get '/' do throw :halt, [400, 'XML-RPC server accepts POST requests only.'] end # get '/' do post '/' do throw :halt, [400, 'bad request type'] unless request.content_type =~ %r|text/xml| headers 'Content-Type' => 'text/xml' begin @responce = @rpc.process(request.body.read) # lets read the content from the client and proccess it rescue RuntimeError header 'Content-Type' => 'text/plain' throw :halt, [400, 'bad request type'] end # rescue end # post '/' do end # Application < Sinatra::Base end # MyModule
