亚马逊S3。最大对象大小 [英] Amazon S3. Maximum object size

问题描述

有没有可能用水桶的策略来设置最大文件（对象）大小？ 我在这里找到了一个<一个href="http://stackoverflow.com/questions/8310462/amazon-s3-bucket-policy-for-anonymously-uploading-photos-to-a-bucket">question像这样，但没有大小限制在实施例

Is there a possibility to set maximum file (object) size using a bucket's policy? I found here a question like this, but there is no size limitation in the examples.

推荐答案

没有，你不能用一个水桶政策，做到这一点。检查<一href="http://docs.amazonwebservices.com/AmazonS3/latest/dev/AccessPolicyLanguage_ElementDescriptions.html#AvailableKeys">Element说明的S3文档的页面的东西，你可以在一个水桶的政策做一个详尽的清单。

No, you can't do this with a bucket policy. Check the Element Descriptions page of the S3 documentation for an exhaustive list of the things you can do in a bucket policy.

不过，您的可以的内的内容长度范围限制：//aws.amazon。 COM /用品/ 1434>浏览器上传的政策文件。此功能通常用于给不可信用户编写的S3存储你的控制（如面向用户​​的媒体上传）内访问特定的键，并提供适当的工具，限制了可没有上载的位置，大小和数据类型需要暴露你的S3凭据。

However, you can specify a content-length-range restriction within a Browser Uploads policy document. This feature is commonly used for giving untrusted users write access to specific keys within an S3 bucket you control (e.g. user-facing media uploads), and it provides the appropriate tools for limiting the location, size, and data types that can be uploaded without needing to expose your S3 credentials.
