我正在写一个Python脚本上传文件使用博托到S3。我想只上传修改过的文件，我可以检查它的最后修改日期时间。但我不能找到API来获取最后的修改博托API。

推荐答案

下面是Python的/博托code片段，将打印所有键的last_modified属性的斗​​：

Here's a snippet of Python/boto code that will print the last_modified attribute of all keys in a bucket:

>>> import boto
>>> s3 = boto.connect_s3()
>>> bucket = s3.lookup('mybucket')
>>> for key in bucket:
       print key.name, key.size, key.last_modified
