Wie Produktbestand von Amazon-Produkt mit AWS API in PHP erhalten?

Question

Ich habe folgenden Code verwendet, um amazon Produktdaten zu bekommen und alle Produkte werden in xml, aber Produkt Lager ist nicht in XML-Inhalt.

Kann mir jemand sagen, wie man Produktinformationen erhält.

<?php 
 
define('AWS_ACCESS_KEY_ID', 'my-access-key'); 
 
define('AWS_SECRET_ACCESS_KEY', 'my-secret-key'); 
 
define('AMAZON_ASSOC_TAG', 'my-associate-tag'); 
 

 
function amazon_get_signed_url($searchTerm) 
 
{ 
 
    $base_url = "http://ecs.amazonaws.com/onca/xml"; 
 
    $params = array('AWSAccessKeyId' => AWS_ACCESS_KEY_ID, 'AssociateTag' => AMAZON_ASSOC_TAG, 'Version' => "2010-11-01", 'Operation' => "ItemLookup", 'Service' => "AWSECommerceService", 'ResponseGroup' => "ItemAttributes", 'ItemId'=> $searchTerm); 
 

 
if(empty($params['AssociateTag'])) 
 
{ 
 
unset($params['AssociateTag']); 
 
} 
 

 
// Add the Timestamp 
 
$params['Timestamp'] = gmdate("Y-m-d\TH:i:s.\\0\\0\\0\\Z", time()); 
 

 
// Sort the URL parameters 
 
$url_parts = array(); 
 
foreach(array_keys($params) as $key) 
 
$url_parts[] = $key . "=" . str_replace('%7E', '~', rawurlencode($params[$key])); 
 
sort($url_parts); 
 
// Construct the string to sign 
 
$url_string = implode("&", $url_parts); 
 
$string_to_sign = "GET\necs.amazonaws.com\n/onca/xml\n" . $url_string; 
 
// Sign the request 
 
$signature = hash_hmac("sha256", $string_to_sign, AWS_SECRET_ACCESS_KEY, TRUE); 
 
// Base64 encode the signature and make it URL safe 
 
$signature = urlencode(base64_encode($signature)); 
 
$url = $base_url . '?' . $url_string . "&Signature=" . $signature; 
 
return ($url); 
 
} 
 

 
$getthis = 'B004XIE6WI'; /*---- Product ASIN-----*/ 
 
$show = amazon_get_signed_url($getthis); 
 

 
$ch = curl_init($show); 
 
curl_setopt($ch, CURLOPT_HEADER, false); 
 
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); 
 
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); 
 
curl_setopt($ch, CURLOPT_TIMEOUT, 15); 
 
$c = curl_exec($ch); 
 
$xml = simplexml_load_string($c); 
 
$json = json_encode($xml); 
 
$array = json_decode($json,TRUE); 
 
echo "<pre>"; 
 
print_r($array); 
 
echo "</pre>"; 
 
?>

Amazon Produkt Api bietet keine Bestandsinformationen. Eine ähnliche Frage wurde ab hier gestellt: How to get remaining stock from Product Advertising API (AWS)
