Service Worker 将文件存储在内容缓存文件中，内容长度为：0

Question

While developing a PWA, I'm using a service worker to download and store files in a cache. I noticed all text resources (json, js, css, html) all had content-length 0 as they were not being cached. While all other files (images, sounds, fonts) had valid content lengths.

I'm using Chrome 89.0.4389.114.

Answer 1

The only common point I noticed was the Accept-Encoding: gzip so I decided to turn compression off. And now it is working. All files have a non 0 length.

Workaround:

I'm using Spring Boot on the server side, so to turn it off, you need to set a property to false.

server.compression.enabled=false
