AmazonServiceException：无法找到凭据

时间：2017-03-21 15:39:53

标签： .net visual-studio amazon-web-services amazon-s3 aws-sdk

在我的生产环境中仅将sdk核心更新到版本3.3.10.2后，我开始遇到此错误。我正在负载均衡器中的4个ec2实例上部署.net api。所有Windows Server 2012 R2。

奇怪的部分，实际上是让我疯狂的部分，如果我在VS 2015中调试它，应用程序运行没有问题，如果我将应用程序发布到我的本地IIS，它运行正常。当我在任何生产机器上部署应用程序时，会发生错误。

我正在使用：

<add key="AWSProfileName" value="{profile name}" />
<add key="AWSProfilesLocation" value="{file location}" />

以及包含相应数据的凭据文件。

在有人要求之前，这个应用程序在这个配置中使用AWS s3已经工作了6个月，并且在凭证或类似的事情上没有任何错误。

更糟糕的是，即使我尝试将aws sdk降级回任何其他版本，错误仍然存​​在。我完全不知道错误来自何处或如何解决它。请帮忙。

这是堆栈跟踪：

答案 0 :(得分：1)

所以这显然是AWSSDK中的一个错误。 3.3.10.3更新后，问题不再存在。感谢您的回复！
