我已经下载了适用于 C# 的 Amazon AWS 开发工具包,我可以毫无问题地访问运行 Eucalyptus 的私有云的 EC2 部分,我可以列出、图像、实例、区域......
这工作正常:
AmazonEC2 ec2 = AWSClientFactory.CreateAmazonEC2Client("abcdefghijklmnopqrstuvwxyz1234567890", "abcdefghijklmnopqrstuvwxyz1234567890", new AmazonEC2Config().WithServiceURL("http://10.140.54.12:8773/services/Eucalyptus"));
DescribeInstancesRequest ec2Request = new DescribeInstancesRequest();
try
{
DescribeInstancesResponse ec2Response = ec2.DescribeInstances(ec2Request);
int numInstances = 0;
numInstances = ec2Response.DescribeInstancesResult.Reservation.Count;
textBoxInstancesLog.AppendText("You have " + numInstances + " running instances");
textBoxInstancesLog.AppendText(ec2Response.ToString());
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
但我需要访问我们云的海象(S3)部分。这就是我尝试访问海象的方式,代码几乎相同,但是通过这个调用我会得到一个异常。
这不起作用:
AmazonS3 s3 = AWSClientFactory.CreateAmazonS3Client("abcdefghijklmnopqrstuvwxyz1234567890", "abcdefghijklmnopqrstuvwxyz1234567890", new AmazonS3Config().WithServiceURL("http://10.140.54.12:8773/services/Walrus"));
ListBucketsRequest s3Request = new ListBucketsRequest();
try
{
ListBucketsResponse s3Response = s3.ListBuckets(s3Request);
textBoxS3Log.AppendText(s3Response.ToString());
}
catch (Exception ex)
{
MessageBox.Show(ex.ToString());
}
我会收到这个例外:
System.Net.WebException: The remote name could not be resolved: 'http'

来自桉树网站:
Eucalyptus 实施 IaaS(基础设施即服务)私有云,可通过与 Amazon EC2 和 Amazon S3 兼容的 API 访问
我错过了什么?
注意:相同的代码在 Amazon S3 上完美运行,问题是访问 Eucalyptus Walrus。
