今天把常用的后台代码整理一下,教程就不用写了,我相信要是涉及到这方面的人,应该不用手把手教的,整理的代码主要有PHP,ASP.NET,JAVA.够爽吧.最近也正在整理FMS2.0应用的各种语言版本的例子,以后可能会爆出来.

先分一下类:HTTPService主要分为普通网页格式调用和,XML方式调用.

Flex(普通形式):

PHP 文件

XML 例子

xmlHttpService.php

<?php
require('shipping.php');

$options = get_shipping_options($_REQUEST["zipcode"], $_REQUEST["pounds"]);

$results[] = "<options>";
foreach ($options as $service => $price) {
$results[] = "<option><service>$service</service><price>$price</price></option>";
}
$results[] = "</options>";
print implode("\n", $results);
?>


shipping.php

<?php
function get_shipping_options($zipcode, $pounds) {
$baseCost = round($zipcode / 10000) + ($pounds * 5);
$options = array( "Next Day" => $baseCost * 4,
"Two Day Air" => $baseCost * 2,
"Saver Ground" => $baseCost);
return $options;
}

?>
