HTTP Examples¶
Writing HTTP Server¶
Intialize an HTTPServer instance
require_once 'jaxl.php';
require_once JAXL_CWD.'/http/http_server.php';
$http = new HTTPServer();
By default HTTPServer will listen on port 9699. You can pass a port number as first parameter to change this.
Define a callback method that will accept all incoming HTTPRequest objects
function on_request($request) {
if($request->method == 'GET') {
$body = json_encode($request);
$request->ok($body, array('Content-Type'=>'application:json'));
}
else {
$request->not_found();
}
}
on_request callback method will receive a HTTPRequest object instance.
For this example, we will simply echo back json encoded $request object for
every http GET request.
Start http server:
$http->start('on_request');
We pass on_request method as first parameter to HTTPServer::start/1.
If nothing is passed, requests will fail with a default 404 not found error message
Writing REST API Server¶
Intialize an HTTPServer instance
require_once 'jaxl.php';
require_once JAXL_CWD.'/http/http_server.php';
$http = new HTTPServer();
By default HTTPServer will listen on port 9699. You can pass a port number as first parameter to change this.
Define our REST resources callback methods:
function index($request) {
$request->send_response(
200, array('Content-Type'=>'text/html'),
'<html><head/><body><h1>Jaxl Http Server</h1><a href="/upload">upload a file</a></body></html>'
);
$request->close();
}
function upload($request) {
if($request->method == 'GET') {
$request->send_response(
200, array('Content-Type'=>'text/html'),
'<html><head/><body><h1>Jaxl Http Server</h1><form enctype="multipart/form-data" method="POST" action=""><input type="file" name="file"/><input type="submit" value="upload"/></form></body></html>'
);
}
else if($request->method == 'POST') {
if($request->body === null && $request->expect) {
$request->recv_body();
}
else {
// got upload body, save it
_debug("file upload complete, got ".strlen($request->body)." bytes of data");
$request->close();
}
}
}
Next we need to register dispatch rules for our callbacks above:
$index = array('index', '^/$');
$upload = array('upload', '^/upload', array('GET', 'POST'));
$rules = array($index, $upload);
$http->dispatch($rules);
Start REST api server:
$http->start();
