27.2    REST

Accessing a REST message is basically very simple. The REST principle means that the data and services are always hidden behind a unique URL. This means that you only need to provide a REST server with a URL structure in which individual methods can be called up. The easiest way to do this is via URL parameters—for example, in the following structure:

• method specifies the method called as a parameter.

• parameter receives an array with the parameters.

Here’s a complete example URL:
