AWS开发工具包CryptProtectData失败 [英] AWS SDK CryptProtectData failed

问题描述

我在.net上使用aws sdk，在emr集群中创建了Pig活动，并在管道中调用

I am using aws sdk for .net, creating a pig activity in an emr cluster and calling in a pipeline,

try
{
    var profileName = ConfigurationManager.AppSettings["AWS_PROFILE_NAME"];
    var accessKey = ConfigurationManager.AppSettings["AWS_ACCESS_KEY"];
    var secretKey = ConfigurationManager.AppSettings["AWS_SECRET_KEY"];

    Amazon.Util.ProfileManager.RegisterProfile(profileName, accessKey, secretKey);

    using (_dataPipelineClient = new AmazonDataPipelineClient(accessKey, secretKey, Amazon.RegionEndpoint.USEast1))
    {
        //proccesing code ...
    }    
}
catch (Exception e)
{
    Logger.Error("ReportScheduler -> Error ocurred.", e);
    throw new Exception("ReportScheduler -> Error ocurred.", e);
}

在我的本地服务器上，一切正常运行都没有问题.但是在托管中会抛出此异常:

in my local server it has no problem everything run perfectly. But in the hosting it throw this exception :

AmazonClientException

AmazonClientException

CryptProtectData失败.

有人可以给我一些有关问题可能出在哪里的想法.

Can someone give me some idea, about where could be the problem.

谢谢.

推荐答案

我遇到了同样的问题，对我有用的是使用基本的AWS凭证而不是商店的凭证.

I got the same issue and what worked for me was to use basic AWS credentials instead of using store ones.

    public static AmazonS3Client GetAwsS3Client(string accessKey, string secretKey)
    {
        var credentials = new BasicAWSCredentials(accessKey, secretKey);

        return new AmazonS3Client(credentials, Amazon.RegionEndpoint.USEast1);
    }
