ctx.body的内容读取不到

[herorest]

根据以往用egg的经验，ctx.body是可以正常读取到资源内容的，但是在本项目中的middleware里，通过读取ctx.body，读取到的是一段流信息，这个我不太懂，麻烦大佬们给看看是咋回事

事情的起因是使用gzip中间件引起，若有别的方式也可以

[zhangyuang]

你的目的是啥？ctx.body在本项目中返回的就是一个stream

[herorest]

该stream流如何来做gzip呢？用原有方式肯定不行了

[herorest]

另外还有个问题，就是js和css并不是走stream流的形式，那这种又怎么开启gzip呢

[zhangyuang]

有很多可以把流 gzip的库，而且gzip这个设置你应该在nginx一层做而不是node

[zhangyuang]

静态文件丢专业的cdn上面去如果你要放本地文件，你应该去看egg的文档如何开启gzip
