Requests to external services
page last edited on 17 April 2015
Sometimes developers need to make a request to some external server and get a response from it. It can be done in order to get shipping rates, for instance. X-Cart has a wrapper around PEAR2 HTTP REQUEST lib that eases such task. This article shows an example of how to create requests to external services via X-Cart.
Table of Contents
In order to show you the facility of making requests, we do not need a new module as we can show it via external X-Cart script. We create the
<X-Cart>/test.php script with the following content:
<?php //X-Cart initializtion require_once 'top.inc.php'; // defining what page we are going to request $url = 'http://www.x-cart.com'; // creating HTTP Request object with a single param: URL $request = new \XLite\Core\HTTP\Request($url); /** Here are main parameters that can be defined for HTTP Request object Data submitted in the request $request->body = $someData; Request headers $request->setHeader('header_name', 'header_value'); Request method. GET is default $request->verb = 'POST'; Setting request timeout value $request->requestTimeout = 30; */ // making request and getting HTTP Response object as a result $response = $request->sendRequest(); // printing result var_dump($response->body);
This script makes a request to x-cart.com and then prints HTML code of its main page as a result.
