library xmlrpc/client

要約

XML-RPC クライアントのためのライブラリです。

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}"

Client with XML-RPC fault-structure handling

There are two possible ways, of handling a fault-structure:

by catching a XMLRPC::FaultException exception

require "xmlrpc/client"

# Make an object to represent the XML-RPC server.
server = XMLRPC::Client.new( "xmlrpc-c.sourceforge.net", "/api/sample.php")

begin
  # 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}"

rescue XMLRPC::FaultException => e
  puts "Error: "
  puts e.faultCode
  puts e.faultString
end

by calling "call2" which returns a boolean

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
ok, result = server.call2("sample.sumAndDifference", 5, 3)

if ok
  sum = result["sum"]
  difference = result["difference"]

  puts "Sum: #{sum}, Difference: #{difference}"
else
  puts "Error: "
  puts result.faultCode
  puts result.faultString
end

Client using Proxy

You can create a +Proxy+ object onto which you can call methods. This way it looks nicer. Both forms, _call_ and _call2_ are supported through _proxy_ and <i>proxy2</i>. You can additionally give arguments to the Proxy, which will be given to each XML-RPC call using that Proxy.

require "xmlrpc/client"

# Make an object to represent the XML-RPC server.
server = XMLRPC::Client.new( "xmlrpc-c.sourceforge.net", "/api/sample.php")

# Create a Proxy object
sample = server.proxy("sample")

# Call the remote server and get our result
result = sample.sumAndDifference(5,3)

sum = result["sum"]
difference = result["difference"]

puts "Sum: #{sum}, Difference: #{difference}"
