如何检查本地服务器中是否启用了deflate？

Chrome开发工具不显示内容编码：

Chrome浏览器似乎出现了问题，我也遇到了同样的问题，虽然deflate在服务器上不起作用，但后来我尝试了Firefox并使用了firebug，它正确地显示了标题中的内容编码

此外，Chrome中下载的文件大小没有显示未压缩的文件大小，而Firefox显示了正确的压缩文件大小。

让我们来测试一下

结论

Chrome当前未显示内容编码。Firefox也不例外。我不知道为什么

现在我知道他们并没有向我展示所有信息，我再也不相信任何一个响应头信息了

一路卷曲。

As@Jay

Chrome当前未显示内容编码。Firefox也不例外。我不知道为什么

截至2018年12月，Chrome和Firefox都出现了相同的行为，Firebug也消失了

为我做的是，在响应标题部分（[F12]->网络选项卡->选择资源->标题选项卡）中显示正确的内容编码

我在弄乱了我的生产服务器两个小时后偶然发现了这一点！我可以确认，截至2017年10月，Chrome+Firefox甚至没有在DevTools中显示主页的压缩线程器，但它们会显示其他所有资源（例如CSS、JS甚至Ajax加载页面）。看这里：提议的卷曲技巧对我来说是可靠的。
