用R、Python或J语言访问AWS中的IMDB数据集

Question

我正在尝试连接到AWS中的IMDB数据集。 我已经注册了AWS并设置了证书。在

我更熟悉R，显然有一个名为aws.s3的R包。当我使用s3HTTP函数时，会出现如下错误

s3HTTP(verb="GET", bucket="imdb-datasets", path="documents/v1/current/name.basics.tsv.gz",
   request_body = "documents/v1/current/name.basics.tsv.gz",
   headers=list('x-amz-request-payer' = "requester"),
   key=Sys.setenv("AWS_ACCESS_KEY_ID"="*******"), secret=Sys.setenv("AWS_SECRET_KEY"="******"))

我的访问密钥是最新的，我没有问题访问我自己的桶。 我还复制了IMDB在他们的网页（http://www.imdb.com/interfaces/）上提供的java示例代码，它似乎没有错误地编译，但是AWS的bucket中没有下载任何文件。在
