Flex: testing/running php proxy locally

October 15, 2010

When accessing URL’s through HttpServices from a remote domain, it often works fine on the local system but fails to connect when the swf is uploaded to the web (google searh ‘flex crossdomain.xml proxy’).

A common way around this is to place a PHP file on your web server that acts as a go-between for the remote site and the swf (an example discussed on Dennis Jaamaan’s site, with proxy code).

This article explains how to setup a local PHP server, and test your PHP proxy locally through Flex Builder 3

1. Download a PHP server: http://www.wampserver.com/en/download.php

2. Install it, leaving whatever default settings it suggests.

3. Click the WampServer taskbar icon, and go to PHP/PHP_extensions/ and click php_curl (need to enable this to use the example below). Then click Start All Services & Put Online.

4. Create a php file named flexProxy.php and put in the code below:

<?php
$ch = curl_init();
$timeout = 30;
$userAgent = $_SERVER['HTTP_USER_AGENT'];

$url = $_REQUEST['url'];
$place = $_REQUEST['place'];

$fullGoogleWeatherPath = $url . $place;

curl_setopt($ch, CURLOPT_URL,$fullGoogleWeatherPath);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
curl_setopt($ch, CURLOPT_USERAGENT, $userAgent);

$response = curl_exec($ch);

if (curl_errno($ch)) {
    echo curl_error($ch);
} else {
    curl_close($ch);
    echo $response;
}
?>

5. Save this file and put it in the localhost directory: C:\wamp\www\
