XML-RPC


XML-RPC and XML-RPC Server Classes

What is XML-RPC?

Quite simply it is a way for two computers to communicate over the internet using XML. One computer, which we will call the client, sends an XML-RPC request to another computer, which we will call the server. Once the server receives and processes the request it will send back a response to the client.

For example, using the MetaWeblog API, an XML-RPC Client (usually a desktop publishing tool) will send a request to an XML-RPC Server running on your site. This request might be a new weblog entry being sent for publication, or it could be a request for an existing entry for editing. When the XML-RPC Server receives this request it will examine it to determine which class/method should be called to process the request. Once processed, the server will then send back a response message.

This can be easily implemented using CodeIgniter’s framework: http://codeigniter.com/

CodeIgniter’s XML-RPC classes permit you to send requests to another server, or set up your own XML-RPC server to receive requests. Overview XML-RPC is a Remote Procedure Calling protocol that works over the Internet.

An XML-RPC message is an HTTP-POST request. The body of the request is in XML. A procedure executes on the server and the value it returns is also formatted in XML. Procedure parameters can be scalars, numbers, strings, dates, etc.; and can also be complex record and list structures.
