c# - 使用错误代码 MovedPermanently 和 Http 状态代码 MovedPermanently 发出请求时出错。服务没有返回更多错误信息？

Question

我使用 aws 工具包 lambda 项目模板创建了一个 aws 示例。并将项目发布到 Aws。

public class Function
{
    IAmazonS3 S3Client { get; set; }

    /// <summary>
    /// Default constructor. This constructor is used by Lambda to construct the instance. When invoked in a Lambda environment
    /// the AWS credentials will come from the IAM role associated with the function and the AWS region will be set to the
    /// region the Lambda function is executed in.
    /// </summary>
    public Function()
    {
        S3Client = new AmazonS3Client();
    }

    /// <summary>
    /// Constructs an instance with a preconfigured S3 client. This can be used for testing the outside of the Lambda environment.
    /// </summary>
    /// <param name="s3Client"></param>
    public Function(IAmazonS3 s3Client)
    {
        this.S3Client = s3Client;
    }

    /// <summary>
    /// This method is called for every Lambda invocation. This method takes in an S3 event object and can be used 
    /// to respond to S3 notifications.
    /// </summary>
    /// <param name="evnt"></param>
    /// <param name="context"></param>
    /// <returns></returns>
    public async Task<string> FunctionHandler(S3Event evnt, ILambdaContext context)
    {
        var s3Event = evnt.Records?[0].S3;
        if(s3Event == null)
        {
            return null;
        }

        try
        {
            var response = await this.S3Client.GetObjectMetadataAsync(s3Event.Bucket.Name, s3Event.Object.Key);
            return response.Headers.ContentType;
        }
        catch(Exception e)
        {
            context.Logger.LogLine($"Error getting object {s3Event.Object.Key} from bucket {s3Event.Bucket.Name}. Make sure they exist and your bucket is in the same region as this function.");
            context.Logger.LogLine(e.Message);
            context.Logger.LogLine(e.StackTrace);
            throw;
        }
    }
}

然后我使用以下 S3 Put 示例测试函数。

{
  "Records": [
    {
      "eventVersion": "2.0",
      "eventTime": "1970-01-01T00:00:00.000Z",
      "requestParameters": {
        "sourceIPAddress": "127.0.0.1"
      },
      "s3": {
        "configurationId": "testConfigRule",
        "object": {
          "eTag": "0123456789abcdef0123456789abcdef",
          "sequencer": "0A1B2C3D4E5F678901",
          "key": "HappyFace.jpg",
          "size": 1024
        },
        "bucket": {
          "arn": "arn:aws:s3:::mybucket",
          "name": "sourcebucket",
          "ownerIdentity": {
            "principalId": "EXAMPLE"
          }
        },
        "s3SchemaVersion": "1.0"
      },
      "responseElements": {
        "x-amz-id-2": "EXAMPLE123/5678abcdefghijklambdaisawesome/mnopqrstuvwxyzABCDEFGH",
        "x-amz-request-id": "EXAMPLE123456789"
      },
      "awsRegion": "us-east-1",
      "eventName": "ObjectCreated:Put",
      "userIdentity": {
        "principalId": "EXAMPLE"
      },
      "eventSource": "aws:s3"
    }
  ]
}

但是，响应出现以下错误？

Answer 1

我意识到这是旧的，但没有答案所以...该错误来自使用错误的区域端点向存储桶发出请求。我可以看到你的设置:

"awsRegion": "us-east-1"

检查存储桶是否在该区域中，如果没有通过配置或在 AmazonS3Client 的构造函数中提供正确的区域。例如

var config = new AmazonS3Config {ServiceURL = bucket, RegionEndpoint = RegionEndpoint.EUWest2};
var client = new AmazonS3Client(new BasicAWSCredentials(s3AccessKey, s3Secret), config);
