amazon-mws 相关问题

亚马逊商城网络服务（亚马逊MWS）是一个集成的Web服务API，可帮助亚马逊卖家以编程方式交换列表，订单，付款，报告等数据。

我使用 cron 作业从亚马逊账户退回订单，它在 2~3 周内运行良好。确实，订单比平时多（由于圣诞节前），看起来像 cron

亚马逊 MWS |安息夏普 |我们计算出的请求签名与您提供的签名不符

我编写了以下方法来从亚马逊获取所有订单。我正在使用 RestSharp 库与 API 进行通信。每次执行请求时，我都会收到以下错误：我写了以下method来获取Amazon的所有订单。我正在使用 RestSharp 库与 API 进行通信。每次执行request我都会收到以下错误： <?xml version="1.0"?> <ErrorResponse xmlns="https://mws.amazonservices.com/Orders/2013-09-01"> <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.</Message> </Error> <RequestID>9f03f5b0-e4e4-4766-a554-00ff970b6b8c</RequestID> </ErrorResponse> 这很奇怪，因为在Amazon Scratchpad（https://mws.amazonservices.de/scratchpad/index.html）上它正在工作，我也得到相同的signature（当我使用计算的时间戳时Scratchpad）在我的c#应用程序中。 C#类 public async void FetchOrders() { RestClient client = new RestClient("https://mws.amazonservices.de"); client.DefaultParameters.Clear(); client.ClearHandlers(); Dictionary<string, string> parameters = new Dictionary<string, string>(); parameters.Add("AWSAccessKeyId", "xxxxxxxxxx"); parameters.Add("Action", "ListOrders"); parameters.Add("CreatedAfter", "2018-01-01T11:34:00Z"); parameters.Add("MarketplaceId.Id.1", "A1PA6795UKMFR9"); parameters.Add("SellerId", "xxxxxxxxx"); parameters.Add("SignatureVersion", "2"); parameters.Add("Timestamp", DateTime.UtcNow.ToString("s") + "Z"); parameters.Add("Version", "2013-09-01"); RestRequest request = new RestRequest("Orders/2013-09-01/", Method.POST); string signature = AmzLibrary.SignParameters(parameters, "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"); request.AddParameter("Signature", signature); foreach (KeyValuePair<string, string> keyValuePair in parameters) { request.AddParameter(keyValuePair.Key, keyValuePair.Value); } IRestResponse result = await client.ExecuteTaskAsync(request); } public static class AmzLibrary { public static string GetParametersAsString(IDictionary<String, String> parameters) { StringBuilder data = new StringBuilder(); foreach (String key in (IEnumerable<String>)parameters.Keys) { String value = parameters[key]; if (value != null) { data.Append(key); data.Append('='); data.Append(UrlEncode(value, false)); data.Append('&'); } } String result = data.ToString(); return result.Remove(result.Length - 1); } public static String SignParameters(IDictionary<String, String> parameters, String key) { String signatureVersion = parameters["SignatureVersion"]; KeyedHashAlgorithm algorithm = new HMACSHA1(); String stringToSign = null; if ("2".Equals(signatureVersion)) { String signatureMethod = "HmacSHA256"; algorithm = KeyedHashAlgorithm.Create(signatureMethod.ToUpper()); parameters.Add("SignatureMethod", signatureMethod); stringToSign = CalculateStringToSignV2(parameters); } else { throw new Exception("Invalid Signature Version specified"); } return Sign(stringToSign, key, algorithm); } private static String CalculateStringToSignV2(IDictionary<String, String> parameters) { StringBuilder data = new StringBuilder(); IDictionary<String, String> sorted = new SortedDictionary<String, String>(parameters, StringComparer.Ordinal); data.Append("POST"); data.Append("\n"); Uri endpoint = new Uri("https://mws.amazonservices.de/Orders/2013-09-01"); data.Append(endpoint.Host); if (endpoint.Port != 443 && endpoint.Port != 80) { data.Append(":") .Append(endpoint.Port); } data.Append("\n"); String uri = endpoint.AbsolutePath; if (uri == null || uri.Length == 0) { uri = "/"; } data.Append(UrlEncode(uri, true)); data.Append("\n"); foreach (KeyValuePair<String, String> pair in sorted) { if (pair.Value != null) { data.Append(UrlEncode(pair.Key, false)); data.Append("="); data.Append(UrlEncode(pair.Value, false)); data.Append("&"); } } String result = data.ToString(); return result.Remove(result.Length - 1); } private static String UrlEncode(String data, bool path) { StringBuilder encoded = new StringBuilder(); String unreservedChars = "abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789-_.~" + (path ? "/" : ""); foreach (char symbol in System.Text.Encoding.UTF8.GetBytes(data)) { if (unreservedChars.IndexOf(symbol) != -1) { encoded.Append(symbol); } else { encoded.Append("%" + String.Format("{0:X2}", (int)symbol)); } } return encoded.ToString(); } private static String Sign(String data, String key, KeyedHashAlgorithm algorithm) { Encoding encoding = new UTF8Encoding(); algorithm.Key = encoding.GetBytes(key); return Convert.ToBase64String(algorithm.ComputeHash( encoding.GetBytes(data.ToCharArray()))); } } 问题是 Request 末尾的 "/"。删除它，一切正常。错了 RestRequest request = new RestRequest("Orders/2013-09-01/", Method.POST); 对 RestRequest request = new RestRequest("Orders/2013-09-01", Method.POST);
