asp.net亚马逊itemsearch

我正在使用visual studio 2008，并尝试做像书或其他东西的API itemsearch。我使用的只是accessKeyId，但是当我点击我的“搜索”按钮来搜索书籍，然后出现签名错误。我是否也需要使用secretKeyID？我刚刚在Visual Studio中创建了新的ASP.Net网站或者我必须使用AWS SDK for.Net包？asp.net亚马逊itemsearch

有人可以请给出一个很好的建议。谢谢！

签名错误表示您没有正确创建请求签名。您应该使用SprightlySoft AWS Component for .NET。它是免费的，它支持产品广告API。获取它在http://sprightlysoft.com/。 AWS SDK for .NET不适用于产品广告API。

以下是使用SprightlySoft组件调用ItemSearch的示例。

//Product Advertising API, ItemSearch: http://docs.amazonwebservices.com/AWSECommerceService/2010-10-01/DG/ItemSearch.html 

SprightlySoftAWS.REST MyREST = new SprightlySoftAWS.REST(); 

String RequestURL; 
RequestURL = "https://ecs.amazonaws.com/onca/xml?Service=AWSECommerceService&Operation=ItemSearch&Version=2010-10-01"; 
RequestURL += "&AWSAccessKeyId=" + System.Uri.EscapeDataString(TextBoxAWSAccessKeyId.Text) + "&SignatureVersion=2&SignatureMethod=HmacSHA256&Timestamp=" + Uri.EscapeDataString(DateTime.UtcNow.ToString("yyyy-MM-dd\\THH:mm:ss.fff\\Z")); 
RequestURL += "&Actor=" + System.Uri.EscapeDataString("Tom Cruise"); 
RequestURL += "&SearchIndex=DVD"; 
RequestURL += "&ResponseGroup=" + System.Uri.EscapeDataString("ItemAttributes,Reviews"); 
RequestURL += "&Sort=salesrank"; 
RequestURL += "&ItemPage=1"; 

String RequestMethod; 
RequestMethod = "GET"; 

String SignatureValue; 
SignatureValue = MyREST.GetSignatureVersion2Value(RequestURL, RequestMethod, "", TextBoxAWSSecretAccessKey.Text); 

RequestURL += "&Signature=" + System.Uri.EscapeDataString(SignatureValue); 

Boolean RetBool; 
RetBool = MyREST.MakeRequest(RequestURL, RequestMethod, null); 
System.Diagnostics.Debug.Print(MyREST.LogData); 

String ResponseMessage = ""; 

if (RetBool == true) 
{ 
    System.Xml.XmlDocument MyXmlDocument; 
    System.Xml.XmlNamespaceManager MyXmlNamespaceManager; 
    System.Xml.XmlNode MyXmlNode; 
    System.Xml.XmlNodeList MyXmlNodeList; 

    MyXmlDocument = new System.Xml.XmlDocument(); 
    MyXmlDocument.LoadXml(MyREST.ResponseString); 

    MyXmlNamespaceManager = new System.Xml.XmlNamespaceManager(MyXmlDocument.NameTable); 
    MyXmlNamespaceManager.AddNamespace("amz", "http://webservices.amazon.com/AWSECommerceService/2010-10-01"); 

    MyXmlNodeList = MyXmlDocument.SelectNodes("amz:ItemSearchResponse/amz:Items/amz:Item", MyXmlNamespaceManager); 

    if (MyXmlNodeList.Count == 0) 
    { 
     ResponseMessage = "No items exist."; 
    } 
    else 
    { 
     foreach (System.Xml.XmlNode ItemXmlNode in MyXmlNodeList) 
     { 
      MyXmlNode = ItemXmlNode.SelectSingleNode("amz:ItemAttributes/amz:Title", MyXmlNamespaceManager); 
      ResponseMessage += "Title = " + MyXmlNode.InnerText; 

      MyXmlNode = ItemXmlNode.SelectSingleNode("amz:ItemAttributes/amz:ListPrice/amz:FormattedPrice", MyXmlNamespaceManager); 
      ResponseMessage += " ListPrice = " + MyXmlNode.InnerText; 

      ResponseMessage += Environment.NewLine; 
     } 
    } 

    MessageBox.Show(ResponseMessage); 
} 
else 
{ 
    MessageBox.Show(MyREST.ResponseStringFormatted); 
}
