javascript - web项目发版如何解决静态资源JS CSS 缓存问题
服务器已设置了缓存，但是发布版本，JS CSS 如果有修改，没有加版本号，如果客户端的浏览器不强制清除所有缓存，还是使用的旧的缓存资源。如何解决静态资缓存本问题？
YII2 使用的是这样的思路吗？每次都检测JS CSS文件的最后修改时间？
如果跟缓存文件的一样，那么不重新生成，否则重新生成缓存的JS CSS文件？

yii的方案就很好，一般都是通过加版本号解决
可以看看laravel的实现。在elixir那部分。原理是读取一个映射文件。这个文件是gulp生成的
用gulp-rev-hash来通过hash区分。
可以使用fis3.为资源文件加md5后缀做区分
md5生产摘要，，作为文件的后缀。。gulp/grunt或者webpack都用相应的方法解决
1、版本号
2、hash命名
建议你看看这个

解决方案上推荐fis~不过RoR,Django这种也都有自己的解决方案，yii2不清楚
