我想使用Feed Api->Sumbit Feed (_POST_INVENTORY_AVAILABILITY_DATA_)
更新亚马逊上的数量
这是我的代码:
$action = 'SubmitFeed';
$path = $_SERVER['DOCUMENT_ROOT'].'/resources/amazon_xml/quantity.xml';
$feed = '<?xml version="1.0" ?><AmazonEnvelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="amzn-envelope.xsd">
<Header>
<DocumentVersion>1.01</DocumentVersion>
<MerchantIdentifier>A3QPCC6I4V1QU3</MerchantIdentifier>
</Header>
<MessageType>Inventory</MessageType>
<Message>
<MessageID>1</MessageID>
<OperationType>Update</OperationType>
<Inventory>
<SKU>6000013953</SKU>
<Quantity>1</Quantity>
</Inventory>
</Message>
</AmazonEnvelope>';
$feedHandle = fopen($path, 'rw+');
fwrite($feedHandle, $feed);
rewind($feedHandle);
$params = array(
'AWSAccessKeyId' => $data['aws_access_key'],
'Action' => $action,
'Merchant' => $data['merchant_id'],
'SignatureMethod' => "HmacSHA256",
'SignatureVersion' => "2",
'Timestamp'=> gmdate("Y-m-d\TH:i:s.\\0\\0\\0\\Z", time()),
'Version'=> "2009-10-01",
'MarketplaceIdList.Id.1' => $data['marketplace_id'],
'FeedType'=> "_POST_INVENTORY_AVAILABILITY_DATA_",
'PurgeAndReplace'=> 'false',
'ContentMd5' => base64_encode(md5(stream_get_contents($feedHandle), true))
);
// 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\nmws.amazonservices.in\n" . $url_string;
// Sign the request
$signature = hash_hmac("sha256", $string_to_sign, $data['aws_secret_key'], TRUE);
// Base64 encode the signature and make it URL safe
$signature = urlencode(base64_encode($signature));
$url = "https://mws.amazonservices.in" . '?' . $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);
//echo $url;exit;
echo '<pre>';
print_r($response);
echo '</pre>';
exit;
但我得到以下回应:
<ErrorResponse xmlns="https://mws.amazonservices.com/">
<Error>
<Type>Sender</Type>
<Code>SignatureDoesNotMatch</Code>
<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.

有人可以告诉我如何将xml文件发送到api吗?还是我做错了什么?
quantity.xml
文件正确更新:-
代码在Amazon Scratchpad上完美运行
最佳答案
Amazon AWS的签名非常善变。 Version 2要求您使用RFC 3986对数据进行编码
将查询字符串组件(名称-值对,不包括初始问号(?))添加为UTF-8字符,这些字符是按RFC 3986 编码的 URL(十六进制字符必须大写),并使用词典顺序对字节进行排序。字节顺序区分大小写。
您的问题似乎出在签名的编码上。$signature = urlencode(base64_encode($signature));
那将不符合RFC3986。PHP可以使用rawurlencode来做到这一点。$signature = rawurlencode(base64_encode($signature));
