自2014年十一月，S3支持以下事件通知：
Since November 2014, S3 supports the following event notifications:
-
S3：ObjectCreated：把- 一个对象是由一个HTTP PUT操作创建 -
S3：ObjectCreated：帖子- 一个对象是由HTTP POST操作创建 -
S3：ObjectCreated：复制- 一个对象被创建的S3复制操作 -
S3：ObjectCreated：CompleteMultipartUpload- 一个对象由完成S3多部分上传的创建 -
S3：ObjectCreated：*- 一个对象已经由以上或在未来增加了一个类似的对象创建事件中列出的事件类型之一创建 -
S3：ReducedRedundancyObjectLost- 存储的精简冗余的S3对象已丢失
s3:ObjectCreated:Put– An object was created by an HTTP PUT operation.s3:ObjectCreated:Post– An object was created by HTTP POST operation.s3:ObjectCreated:Copy– An object was created an S3 copy operation.s3:ObjectCreated:CompleteMultipartUpload– An object was created by the completion of a S3 multi-part upload.s3:ObjectCreated:*– An object was created by one of the event types listed above or by a similar object creation event added in the future.s3:ReducedRedundancyObjectLost– An S3 object stored with Reduced Redundancy has been lost.

原来的答案：
尽管亚马逊S3有一个桶的通知制度，它不支持通知的任何东西，但 S3：ReducedRedundancyLostObject 的事件（见的获取桶的通知的在他们的API部分）。
Although Amazon S3 has a bucket notifications system in place it does not support notifications for anything but the s3:ReducedRedundancyLostObject event (see the GET Bucket notification section in their API).
目前，以检查是否有新对象的唯一方法是轮询桶在preset的时间间隔，或建立自己的通知逻辑上传客户端（可能基于亚马逊SNS）。
Currently the only way to check for new objects is to poll the bucket at a preset time interval or build your own notification logic in the upload clients (possibly based on Amazon SNS).
