亚马逊MWS订单签名不匹配
当我运行此代码时，出现SignatureDoesNotMatch错误我们计算的请求签名与您提供的签名不匹配。 检查您的AWS秘密访问密钥和签名方法。 详细信息请参阅服务文档。
<?php
$param = array();
$param['AWSAccessKeyId'] = 'AWSAccessKeyId';
$param['Action'] = 'ListOrders';
$param['MWSAuthToken'] = 'MWSAuthToken';

$param['FulfillmentChannel.Channel.1'] = 'MFN';
$param['PaymentMethod.Method.1'] = 'COD';
$param['OrderStatus.Status.1'] = 'Pending';
$param['OrderStatus.Status.2'] = 'PendingAvailability';
$param['SellerId'] = 'AGNFZGZRZBUP1';
$param['SignatureMethod'] = 'HmacSHA256';
$param['SignatureVersion'] = '2';
$param['CreatedAfter'] = "2017-09-01T13:41:49Z";
$param['Timestamp'] = gmdate("Y-m-dTH:i:s. Z", time());

$secret = 'secret key';
$url = array();
foreach ($param as $key => $val) {
$val = str_replace("%7E", "~", rawurlencode($val));
$url[] = $key . "=" . $val;
}
sort($url);
$arr = implode('&', $url);
$sign = 'POST' . "n";
$sign .= 'mws.amazonservices.in' . "n";
$sign .= '/Orders/2013-09-01' . "n";
$sign .= $arr;
$signature = hash_hmac("sha256", $sign, $secret, true);
$signature = urlencode(base64_encode($signature));
$link = "https://mws.amazonservices.in/Orders/2013-09-01?";
$link .= $arr;
$link .= "&Signature=" . $signature;
echo($link); //for debugging - you can paste this into a browser and see if it loads.
$ch = curl_init($link);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-type: application/xml'));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
$response = curl_exec($ch);
$info = curl_getinfo($ch);
curl_close($ch);
echo "<pre>";
print_r($response);
print_r($info);
?>
你的签名计算似乎很好。 但是，您正在计算基于“POST”的签名，但实际上您正在执行GET。 我想这就是抛开另一边的签名计算。
