如何在AWS CloudFront上启用gzip压缩 [英] How to enable gzip compression on AWS CloudFront

问题描述

我试图gzip压缩通过 CloudFront 提供的img。我的出身是 S3

I m trying to gzip compress the img I m serving through CloudFront. My origin is S3

根据有关AWS的几篇文章/博客，我所做的是：

Based on several articles/blogs on aws, what I did is:

1）为要压缩的对象设置 Content-Length 标头。我将值设置为等于 size 属性框上出现的大小

1) Set "Content-Length" header for the object I want to compress. I set the value equal to the size appeared on the size property box

2）设置在我的云分布的行为中，将对象自动压缩的值为是。

2) Set the Compress Objects Automatically value to Yes in the Behaviour of my cloud distribution.

3）我使我的对象无效，无法从 S3 获得新副本。

3) I invalidated my object to get a fresh copy from S3.

仍然无法将 CloudFront gzip用作我的对象。有想法吗？

Still I m not able to make CloudFront gzip my object. Any ideas?

推荐答案

我正在尝试gzip压缩[image]

I'm trying to gzip compress the [image]

通常不需要gzip图像-这样可以节省很少的带宽（如果有的话），因为实际上网络上使用的所有图像格式都是

You don't typically need to gzip images -- doing so saves very little bandwidth, if any, since virtually all image formats used on the web are already compressed.

此外，CloudFront不支持它。

Also, CloudFront doesn't support it.

请参见 CloudFront压缩的文件类型用于支持的文件格式。它们是基于文本的格式，通常会从gzip压缩中受益匪浅。

See File Types that CloudFront Compresses for the suported file formats. They are text-based formats, which tend to benefit substantially from gzip compression.

如果您真的希望将文件压缩后，可以存储

If you really want the files served gzipped, you can store the files in S3, already gzipped.

$ gzip -9 myfile.png

这将创建一个压缩文件 myfile.png.gz 。

This will create a gzipped file myfile.png.gz.

将文件上传到S3 最后而没有.gz。将 Content-Encoding：标头设置为 gzip 并设置 Content-Type：标头指向文件的正常正确值，例如 image / png 。

Upload the file to S3 without the .gz on the end. Set the Content-Encoding: header to gzip and set the Content-Type: header to the normal, correct value for the file, such as image/png.

这会破坏所有不理解 Content-Encoding：gzip 的浏览器，但是使用的浏览器不应有该限制。

This breaks any browser that doesn't understand Content-Encoding: gzip, but there should be no browsers in use that have that limitation.

请注意，上面的 -9 表示最大压缩。

Note that the -9, above, means maximum compression.
