我们正在尝试访问亚马逊MWS Api,但我们无法让它工作,我们也不知道为什么。 这是我们到目前为止所尝试的:
require_once('.config.inc.php');
$base_url = "https://mws.amazonservices.de/Products/2011-10-01";
$method = "POST";
$host = "mws.amazonservices.de";
$uri = "/Products/2011-10-01";
$params = array(
'AWSAccessKeyId' => <our Key>,
'Action' => "GetLowestOfferListingsForASIN",
'SellerId' => <our ID>,
'SignatureMethod' => "HmacSHA256",
'SignatureVersion' => "2",
'Timestamp'=> gmdate("Y-m-d\TH:i:s.\\0\\0\\0\\Z", time()), //tried this with time()+7200 since our server is 2 hours back but we also accessed mws to get the time used there
'Version'=> "2011-10-01",
'MarketplaceId' => <our MpID>,
'ItemCondition' => 'new',
'ASINList.ASIN.1' => B00NN8LSXY );
// 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 = "POST\nmws.amazonservices.de\n/Products/2011-10-01\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 = "https://mws.amazonservices.de/Products/2011-10-01" . '?' . $url_string . '&Signature=' . $signature;
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_TIMEOUT, 15);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
$response = curl_exec($ch);
//$parsed_xml = simplexml_load_string($response);
echo $response;
//return ($parsed_xml);
在我们添加的.config.inc.php文件中 所有的钥匙和钥匙ID +
define('APPLICATION_NAME', '<our Firm>');
define('APPLICATION_VERSION', '1.0');
在我们完成所有操作之前,我们检查了MWS-Scratchpad中的所有内容,但一切似乎都在那里工作(在mws.amazon.de上)。
但我们仍然获得SignatureDoesNotMatch错误代码
<Message>The request signature we calculated does not match the signature you provided. Check your AWS Secret Access Key and signing method. Consult the service documentation for details.</Message>
或此错误代码:
<Message>Request signature is for too far in the future. Timestamp date: 2015-05-23T04:54:38.000Z. Currently, 10 percent of requests that are more than 15 minutes in the future will be rejected.</Message>
希望有人可以帮助我们浏览所有其他帖子和开发者指南 - 这似乎没什么帮助

我遇到了同样的问题(等等)。
亚马逊提供的PHP参考和示例的答案深埋在其中。整个事情是烤宽面条代码的一个典型例子,读起来像是对各地编码员的侮辱。
API期望HTTP POST包含所有请求数据以及使用您的密钥进行签名。数组的排序和url编码标准将字符串更改为sign。
亚马逊预计它的排序方式如下:
uksort($params, 'strcmp');
忘记整个$ url_parts部分,这很麻烦。使用http_build_query()代替:
$url_string = http_build_query($params,'','&',PHP_QUERY_RFC3986);
亚马逊期望RFC3986,因此空格编码为'+',而不是'%20'。时间戳也应如下所示:
'Timestamp' => gmdate("Y-m-d\TH:i:s\\Z", time()),
祝你好运。

当您的机器/服务器时间不正确时会发生这种情况。有时当我重启它时,它会发生在我的服务器上。只需使用时间服务器设置同步。
