docker - Cognito身份System.IO.InvalidDataException:无法确定协议(protocol)。在Elastic beantalk上的docker中运行时

在Elastic beanstalk中的docker容器中运行我的应用程序时，我注意到此错误。提取用户和登录操作可以正常工作，但是尝试创建新用户会引发此错误。

针对同一个Cognito实例在本地进行开发不会发生此问题。我认为这与从附加到 flex beantalk实例的IAM角色中获取权限有关。

flex beantalk实例的IAM实例配置文件附加了AmazonCognitoPowerUser策略。这与我用于本地开发的用户所附加的策略相同

堆栈跟踪:

System.IO.InvalidDataException: Cannot determine protocol
at Amazon.Runtime.Internal.Signer.SignRequest(IRequestContext requestContext)
at Amazon.Runtime.Internal.Signer.PreInvoke(IExecutionContext executionContext)
at Amazon.Runtime.Internal.Signer.InvokeAsync[T](IExecutionContext executionContext)
at Amazon.Runtime.Internal.CredentialsRetriever.<InvokeAsync>d__7`1.MoveNext()

错误出现的相关代码:

private static AmazonCognitoIdentityProviderClient Client => new AmazonCognitoIdentityProviderClient(Amazon.RegionEndpoint.APSoutheast2);

var signUpRequest = new SignUpRequest
        {
            ClientId = AWSCognitoClientId,
            Username = email,
            Password = password
        };

        await Client.SignUpAsync(signUpRequest);

我不确定这是不是SDK中的错误或 flex beantalk实例的配置错误

最佳答案

我可以通过使用AmazonCognitoIdentityProviderClient实例化AnonymousAWSCredentials来解决它，如此处建议的:https://github.com/aws/aws-sdk-net/issues/937#issuecomment-415454184。

var forgotPasswordRequest = new ForgotPasswordRequest
{
    // ...
};

using (var identityProvider = new AmazonCognitoIdentityProviderClient(new Amazon.Runtime.AnonymousAWSCredentials()))
{
    return identityProvider.ForgotPasswordAsync(forgotPasswordRequest);
}

我正在使用Cognito的ForgotPassword / ForgotPasswordAsync .NET SDK遇到此问题。

identityProvider.ForgotPasswordAsync(forgotPasswordRequest);

它在抛出:

System.IO.InvalidDataException: Cannot determine protocol
at Amazon.Runtime.Internal.Signer.SignRequest(IRequestContext requestContext)
at Amazon.Runtime.Internal.Signer.PreInvoke(IExecutionContext executionContext)
at Amazon.Runtime.Internal.Signer.InvokeAsync[T](IExecutionContext executionContext)
