任何人都可以在不使用 AWS sdk for .net 的情况下帮助我在 c# 中使用这个 REST api“描述桉树实例”示例吗？我给你我的示例代码。此代码在 aws 中成功运行，但在 eucalyptus 中它们给出“404 not found”错误。
protected void Page_Load(object sender, EventArgs e)
{
EucaListInstance("xyx/services/Eucalyptus");
}
private void ListEucaInstance(string inboundQueueUrl)
{
// Create a request for the URL.
string date = System.DateTime.UtcNow.ToString("s");
string stringToSign = string.Format("DescribeInstances" + date);
string signature = CalculateEucaSignature(stringToSign, true);
StringBuilder sb = new StringBuilder();
sb.Append(inboundQueueUrl);
sb.Append("?Action=DescribeInstances");
sb.Append("&Version=2013-10-15");
sb.AppendFormat("&AWSAccessKeyId={0}", m_EucaAccessKeyID);
sb.AppendFormat("&Expires={0}", date);
sb.AppendFormat("&Signature={0}", signature);
HttpWebRequest request = (HttpWebRequest)WebRequest.Create(sb.ToString());
HttpWebResponse response = null;
Stream dataStream = null;
StreamReader reader = null;
try
{
request.Credentials = CredentialCache.DefaultCredentials;
response = (HttpWebResponse)request.GetResponse();
// Get the stream containing content returned by the server.
dataStream = response.GetResponseStream();
// Open the stream using a StreamReader for easy access.
reader = new StreamReader(dataStream);
}
catch (Exception ex)
{
Console.WriteLine(ex.Message);
}
finally
{
// Cleanup the streams and the response.
if (reader != null)
reader.Close();
if (dataStream != null)
dataStream.Close();
if (response != null)
response.Close();
}
}
private string CalculateEucaSignature(string data, bool urlEncode)
{
ASCIIEncoding ae = new ASCIIEncoding();
HMACSHA1 signature = new HMACSHA1(ae.GetBytes(m_EucaSecretKey));
string retSignature = Convert.ToBase64String(signature.ComputeHash(ae.GetBytes(data.ToCharArray())));
return urlEncode ? HttpUtility.UrlEncode(retSignature) : retSignature;
}
