我正在尝试通过 Amazon API 获取搜索结果列表，以在我的网站上列出产品。除了指定我要检索的页码外，一切正常。由于某种原因，它总是获取第 1 页。
$SecretAccessKey = "xxx";
$request['AWSAccessKeyId'] = "xxx";
$request['AssociateTag'] = "xxx";
$request['Timestamp'] = gmdate("Y-m-d\TH:i:s\Z");
$request['ResponseGroup'] = "ItemAttributes,Offers,Images";
$request['ItemPage'] = 1;
$request['Service'] = 'AWSECommerceService';
$request['Version'] = '2011-08-01';
$request['Operation'] = 'ItemSearch';
$request['SearchIndex'] = $search['category_name'];
$request['Keywords'] = $search['text'];
$request['Page'] = 5;
ksort($request); // Sorts in order of key
$Prepend = "GET\nwebservices.amazon.com\n/onca/xml\n";
$String = http_build_query($request);
$PrependString = str_replace('+', '%20', $Prepend . $String);
$Signature = base64_encode(hash_hmac("sha256", $PrependString, $SecretAccessKey, True));
$Signature = urlencode($Signature);
$BaseUrl = "http://webservices.amazon.com/onca/xml?";
$SignedRequest = $BaseUrl . $String . "&Signature=" . $Signature;
// Fetch the generated URL
$xml = simplexml_load_file($SignedRequest);
我试过用$request['Page'],$request['page']和. 似乎没有一个可以拉出正确的页面。有谁知道这个参数应该被命名为什么？$request['Pages']$request['pages']
