Everything that runs in the web in the XP Framework, is a scriptlet, at the beginning. Every higher-class API is derived from the simple HttpScriptlet class: RestScriptlet, WorkflowScriptlet, ...
The scriptlet.HttpScriptlet class is the base class for any so-called scriptlet. A scriptlet is something that can serve HTTP requests.
The simplest form of answering an HTTP request in XP Framework goes like this:
namespace com\example\web;
class HelloScriptlet extends \scriptlet\HttpScriptlet {
/**
* Perform GET request
*
* @param scriptlet.Request $request
* @param scriptlet.Response $response
* @throws scriptlet.ScriptletException
*/
public function doGet($request, $response) {
$response->write(sprintf('<!DOCTYPE html>
<html>
<head><title>Hello World scriptlet</title></head>
<body>
<h1>Hello %s</h1>
</body>
</html>',
htmlspecialchars($request->getParam('name', 'World'))
));
}
}This code generates a HTML page that shows a headline "Hello World" or "Hello $something" when something was given as GET-parameter "name".
Override doPost() or any of the other methods named after HTTP request types to serve these request types, as well.
Use the xpws runner to serve your scriptlet:
$ xpws -c com.example.web.HelloScriptlet
