Question

我正在使用AWS Secrets Manager存储一些API密钥。在AWS Secrets Manager控制台中配置后，我尝试使用其示例代码来检索我存储的机密。这是应该使用的代码：

public static void GetSecret()
        {
            string secretName = "XYXYXYX";
            string region = "us-west-2";
            string secret = "";

            MemoryStream memoryStream = new MemoryStream();

            IAmazonSecretsManager client = new AmazonSecretsManagerClient(RegionEndpoint.GetBySystemName(region));
            //IAmazonSecretsManager client = new AmazonSecretsManagerClient((new StoredProfileAWSCredentials()));
            GetSecretValueRequest request = new GetSecretValueRequest();
            request.SecretId = secretName;
            request.VersionStage = "AWSCURRENT"; // VersionStage defaults to AWSCURRENT if unspecified.

            GetSecretValueResponse response = null;

            // In this sample we only handle the specific exceptions for the 'GetSecretValue' API.
            // See https://docs.aws.amazon.com/secretsmanager/latest/apireference/API_GetSecretValue.html
            // We rethrow the exception by default.

            try
            {
                response = client.GetSecretValueAsync(request).Result;
            }
            catch (DecryptionFailureException e)
            {
                // Secrets Manager can't decrypt the protected secret text using the provided KMS key.
                // Deal with the exception here, and/or rethrow at your discretion.
                throw;
            }
            catch (InternalServiceErrorException e)
            {
                // An error occurred on the server side.
                // Deal with the exception here, and/or rethrow at your discretion.
                throw;
            }
            catch (InvalidParameterException e)
            {
                // You provided an invalid value for a parameter.
                // Deal with the exception here, and/or rethrow at your discretion
                throw;
            }
            catch (InvalidRequestException e)
            {
                // You provided a parameter value that is not valid for the current state of the resource.
                // Deal with the exception here, and/or rethrow at your discretion.
                throw;
            }
            catch (ResourceNotFoundException e)
            {
                // We can't find the resource that you asked for.
                // Deal with the exception here, and/or rethrow at your discretion.
                throw;
            }
            catch (System.AggregateException ae)
            {
                // More than one of the above exceptions were triggered.
                // Deal with the exception here, and/or rethrow at your discretion.
                throw;
            }

            // Decrypts secret using the associated KMS CMK.
            // Depending on whether the secret is a string or binary, one of these fields will be populated.
            if (response.SecretString != null)
            {
                secret = response.SecretString;
            }
            else
            {
                memoryStream = response.SecretBinary;
                StreamReader reader = new StreamReader(memoryStream);
                string decodedBinarySecret = System.Text.Encoding.UTF8.GetString(Convert.FromBase64String(reader.ReadToEnd()));
            }

            // Your code goes here.
        }

当我尝试运行此命令时，出现以下错误：

System.AggregateException: 'https://secretsmanager.us-west-2.amazonaws.comgisteredAccounts.jsonET_Core/3.1.4 OS/Microsoft_Windows_6.)'


Inner Exception
AmazonServiceException: Unable to get IAM security credentials from EC2 Instance Metadata Service.

我正在使用适用于VS2019的AWS工具箱，并且确实验证了凭据是否正确（我能够直接从工具箱访问S3存储桶对象）。

要获取秘密还需要做其他事情吗？

问题在于env变量中的默认配置文件不可用。我使用AWS configure设置默认配置文件的凭证，并按如下所示修改了客户端的创建：

var config = new AmazonSecretsManagerConfig { RegionEndpoint = RegionEndpoint.USWest2 };
IAmazonSecretsManager client = new AmazonSecretsManagerClient(config);

一旦完成，我就能揭开秘密

使用Visual Studio工具箱检索AWS机密
