我已经在工作箱 2 中实现了这个类,现在我已经升级到版本 3,但不推荐使用 workbox.runtimeCaching.Handler。
有人可以帮助我如何在工作箱 3 中开发它吗?*
importScripts('workbox-sw.prod.v2.1.2.js');
importScripts('workbox-runtime-caching.prod.v2.0.3.js');
importScripts('workbox-cache-expiration.prod.v2.0.3.js');
const workboxSW = new self.WorkboxSW();
class AlwaysNetworkWithCacheUpdateHandler extends workbox.runtimeCaching.Handler{
setCacheOptions(cacheOptions){
this.cacheOptions = cacheOptions;
}
handle({event}){
let requestWrapper = new workbox.runtimeCaching.RequestWrapper({
cacheName: this.cacheOptions.cacheName,
plugins:[
new workbox.cacheExpiration.CacheExpirationPlugin(this.cacheOptions.expirationOptions)
]
});
return (
requestWrapper
.fetchAndCache({
request: event.request,
waitOnCache: true
})
);
}
}
