          Action:
          - s3:GetObject
          - s3:PutObject
          - s3:PutBucketCORS
          - s3:PutObjectAcl

BucketKey:
    Type: AWS::IAM::AccessKey
    Properties:

    Export:
      Name: BucketKey
  SecretAccessKey:

检查 AWS::S3::Bucket

对于WebsiteURL输出，请尝试：

WebsiteURL:
  Value: !GetAtt S3Bucket.WebsiteURL
  Export:
    Name: S3Bucket
