Ruby is an
object-oriented scripting language. It already has a major following in
Japan, and it's becoming popular elsewhere.
To use XML-RPC with Ruby, you must first install Yoshida Masato's
xmlparser module (a wrapper for James Clark's expat parser). This can
be found at the Ruby
Application Archive.
Then, you must install xmlrpc4r
using the following commands:
bash$ tar -xvzf xmlrpc4r-1_2.tar.gz
bash$ cd xmlrpc4r-1_2
bash$ su root -c "ruby install.rb" |
Here's a simple Ruby client:
require "xmlrpc/client"
# Make an object to represent the XML-RPC server.
server = XMLRPC::Client.new( "xmlrpc-c.sourceforge.net", "/api/sample.php")
# Call the remote server and get our result
result = server.call("sample.sumAndDifference", 5, 3)
sum = result["sum"]
difference = result["difference"]
puts "Sum: #{sum}, Difference: #{difference}" |
Here's a simple Ruby server:
require "xmlrpc/server"
s = XMLRPC::CGIServer.new
s.add_hanlder("sample.sumAndDifference") do |a,b|
{ "sum" => a + b, "difference" => a - b }
end
s.serve |
This could also have been written as follows:
require "xmlrpc/server"
s = XMLRPC::CGIServer.new
class MyHandler
def sumAndDifference(a, b)
{ "sum" => a + b, "difference" => a - b }
end
end
s.add_handler("sample", MyHandler.new)
s.serve |
To run either server in standalone mode, replace the second line
of code with the following:
s = XMLRPC::Server.new(8080) |
