How to create RESTfull webservice in Zend framework? - zend-framework

Question

I am new for zend.i need to create web-service in zend using Zend_Json_Server with JSON responce. I have define api controller here..
<?php
class ApiController extends Zend_Controller_Action
{
public function init()
{ }
public function indexAction()
{ }
public function restAction()
{
// disable layouts and renderers
$this->getHelper('viewRenderer')->setNoRender ( true );
// initialize REST server
$server = new Zend_Json_Server();
// set REST service class
$server->setClass('Test_Return');
// handle request
if ('GET' == $_SERVER['REQUEST_METHOD']) {
$server->setTarget('/json-rpc.php')
->setEnvelope(Zend_Json_Server_Smd::ENV_JSONRPC_2);
$smd = $server->getServiceMap();
// Set Dojo compatibility:
// $smd->setDojoCompatible(true);
header('Content-Type: application/json');
echo $smd;
}
$server->handle();
}
}
?>
And Test_Return define in Library/Test
Test_Return code is here..
<?php
class Test_Return {
public function add($x, $y)
{
return $x + $y;
}
public function subtract($x, $y)
{
return $x - $y;
}
public function multiply($x, $y)
{
return $x * $y;
}
public function divide($x, $y)
{
return $x / $y;
}
} ?>
How can call particular expression.

Answer 1

As describe in here on your index you create an instance of the zend_rest_server add your methods and run it. The methods should be specified in the url. I sugest you chose zend 2 for better implementation

Answer 2

The Zend_Json_Server initialization should be in your public/index.php
defined('APPLICATION_PATH') ||
define('APPLICATION_PATH', realpath(dirname(__FILE__) . '/../application'));
defined('APPLICATION_ENV') ||
define('APPLICATION_ENV', (getenv('APPLICATION_ENV') ? getenv('APPLICATION_ENV') : 'production'));
set_include_path(implode(PATH_SEPARATOR, array(
dirname(dirname(__FILE__)) . '/libs',
get_include_path(),
)));
require_once 'Zend/Application.php';
$application = new Zend_Application(
APPLICATION_ENV, APPLICATION_PATH . '/configs/application.ini');
$application->getBootstrap()->bootstrap();
// Instantiate server ...
$server = new Zend_Json_Server();
include_once APPLICATION_PATH . '/Calculator.php';
$server->setClass(new Calculator());
if ('GET' == $_SERVER['REQUEST_METHOD'])
{
// Indicate the URL endpoint, and the JSON-RPC version used:
$server->setTarget('/api/1.0/jsonrpc.php')->setEnvelope(Zend_Json_Server_Smd::ENV_JSONRPC_2);
// Grab the SMD
$smd = $server->getServiceMap();
// Return the SMD to the client
header('Content-Type: application/json');
echo $smd;
return;
}
$server->handle();
$application->bootstrap()->run();
With curl on the command line you wont see anything ;-). This frustrated me a bit.
curl -H "Content-Type: application/json" -d '{"method":"add","x":5,"y":10}' http://zend.rest.server/api/1.0/jsonrpc.php
On the browser you can use this jQuery plugin
app = jQuery.Zend.jsonrpc({url: '/api/1.0/jsonrpc'});
app.add(5, 5);
{"result":10,"id":"1","jsonrpc":"2.0"}
You maybe want to follow the steps as describe here.
I suggest that you apgrade your version of zend if you can as zend2.X.X has better support for rest services.
