为了记录，从关于问题的讨论中，这里是一个用于查看和数据的 PHP 示例，可在 this blog post 获得。
<?php
// we need a REST Library, found HttpFul
// Download from http://phphttpclient.com/
// You may need to add permissions for MAC OS with Apache
// sudo chmod -R 755 /library/webserver/documents
// (assuming default folder)
include 'httpful.phar';
// define some constants for this quick sample
define(CONSUMER_KEY, "your key");
define(CONSUMER_SECRET, "your secret");
define(BASE_URL, 'https://developer.api.autodesk.com');
// if the request URL contains the method being requested
// for instance, a call to view.and.data.php/authenticate
// will redirect to the function with the same name
$apiName = explode('/', trim($_SERVER['PATH_INFO'],'/'))[0];
if (!empty($apiName)){
// get the function by API name
try{ $apiFunction = new ReflectionFunction($apiName);}
catch (Exception $e) { echo ('API not found');}
// run the function and 'echo' it's reponse
if ($apiFunction != null) echo $apiFunction->invoke();
exit(); // no HTML output
}
// now the APIs
function authenticate(){
// request body (client key & secret)
$body = sprintf('client_id=%s' .

<div>This is a minimum sample in PHP5.
<br /> First edit this file and enter your consumer key and consumer secret. Request at <a href="http://forge.autodesk.com">Forge portal</a>.
<br /> To use this sample you need a model URN. Please upload a model at <a href="http://models.autodesk.io">Models.Autodesk.IO</a></div>
