如何在php中使用AWS api获取亚马逊产品的产品库存？

Question

I have used following code for getting amazon product data and all products are getting in xml but product stock is not there in xml content.

Can anyone guide me for how to get product stock information.

 <?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("Ymd\\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 Product Api does not provide stock information. A similar question was asked here: How to get remaining stock from Product Advertising API (AWS)
