如何判断我的服务器是否正在提供 GZipped 内容? [英] How can I tell if my server is serving GZipped content?

问题描述

我在 NGinx 服务器上有一个 web 应用程序.我在 conf 文件中设置了 gzip on，现在我想看看它是否有效.YSlow 说它不是，但是进行测试的 6 个网站中有 5 个说它是.我如何才能得到明确的答案，为什么结果会有所不同?

I have a webapp on a NGinx server. I set gzip on in the conf file and now I'm trying to see if it works. YSlow says it's not, but 5 out of 6 websites that do the test say it is. How can I get a definite answer on this and why is there a difference in the results?

推荐答案

看起来一个可能的答案是，不出所料，curl:

It looks like one possible answer is, unsurprisingly, curl:

$ curl http://example.com/ --silent --write-out "%{size_download}
" --output /dev/null
31032
$ curl http://example.com/ --silent -H "Accept-Encoding: gzip,deflate" --write-out "%{size_download}
" --output /dev/null
2553

在第二种情况下，客户端告诉服务器它支持内容编码，您可以看到响应确实更短、压缩了.

In the second case the client tells the server that it supports content encoding and you can see that the response was indeed shorter, compressed.
