亚马逊AWS:无法登录

本文关键字：登录 AWS 亚马逊 | 更新日期: 2023-09-27 18:15:27

我一直在做一个amazon EC2项目，当我这样登录时:

public bool Login(Credentials credentials, string ownerID, string region)
{
    try
    {
        OwnerID = ownerID;
        CurrentCredentials = credentials;
        CurrentConfigs = new AmazonEC2Config() { RegionEndpoint = RegionEndpoint.GetBySystemName(region) };
        EC2 = AWSClientFactory.CreateAmazonEC2Client(CurrentCredentials, CurrentConfigs);
    }
    catch
    {
        return false;
    }
    return true;
}

然后尝试像这样访问:

DescribeInstancesRequest ec2Request = new DescribeInstancesRequest();
ec2Request.InstanceIds = new List<string>() { id };
DescribeInstancesResponse ec2Response = EC2.DescribeInstances(ec2Request);
return ec2Response.Reservations[0].Instances[0];

我得到了这个异常:

例外:

Encountered a WebException (NameResolutionFailure), the request cannot be retried. Either the maximum number of retries has been exceeded (4/4) or the request is using a non-seekable stream.

堆栈跟踪:

at Amazon.Runtime.AmazonWebServiceClient.HandleHttpWebErrorResponse(AsyncResult asyncResult, WebException we)
at Amazon.Runtime.AmazonWebServiceClient.getRequestStreamCallback(IAsyncResult result)
at Amazon.Runtime.AmazonWebServiceClient.endOperation[T](IAsyncResult result)
at Amazon.EC2.AmazonEC2Client.DescribeInstances(DescribeInstancesRequest describeInstancesRequest)
at ...
编辑:

这个异常的内部异常是:

The remote name could not be resolved: 'ec2.sa-east-1a.amazonaws.com'

重要的是要指出，只有当访问区域sa-east-1a时才会给我这个错误。我在区域us-west-2的另一个帐户工作完美。此外，我还从web.config

亚马逊AWS:无法登录

中提取了凭据和区域信息。

简单的错误，简单的解决方法:区域是sa-east-1而不是sa-east-1a。登录时，不应该指定要使用哪个数据中心，而应该指定区域。

作为本文的附录，给那些没有指定数据中心的人。在我的案例中，使用RegionEndpoint.GetBySystemName("USEast1")和RegionEndpoint.GetBySystemName("US-East-1")是差异制造者。
