我正在创建一个页面,当用户离线时会显示一条消息,但当我的服务工作者尝试缓存该页面时,总是会抛出Chrome控制台:
service-worker.js?v = 1:1 Uncaught(在promise中)DOMException:Quota 超标。 Promise被拒绝(异步)addEventListener.event @ ?服务worker.js V = 1:10
服务工作者注册:
if ('serviceWorker' in navigator) {
navigator.serviceWorker.register('./assets/app/js/service-worker.js?v=1').then(function(registration) {
// Registration was successful
console.log('ServiceWorker registration successful with scope: ', registration.scope);
}).catch(function(err) {
// registration failed :(
console.log('ServiceWorker registration failed: ', err);
});}
服务工作者:
'use strict';
var cacheVersion = 1;
var currentCache = {
offline: 'offline-cache' + cacheVersion
};
var offlineUrl = '../../../offline.html';
this.addEventListener('install', event => {
event.waitUntil(
caches.open(currentCache.offline).then(function (cache) {
return cache.addAll([
offlineUrl
]);
})
);
});
this.addEventListener('fetch', event => {
if (event.request.mode === 'navigate' || (event.request.method === 'GET' && event.request.headers.get('accept').includes('text/html'))) {
event.respondWith(
fetch(event.request.url).catch(error => {
return caches.match(offlineUrl);
})
);
}
else {
event.respondWith(caches.match(event.request)
.then(function (response) {
return response || fetch(event.request);
})
);
}
});
offline.html:
<div> offline test </div>
我已经删除了所有缓存,并且说“超出配额”,任何想法?
感谢。

如果您想在生产中使用服务工作者,我建议使用 sw-precache 插件(用于gulp或web pack)或工作箱。之后,您可以在bundler中设置缓存文件URL。来自真实项目的 webpack 和 sw-precache 的示例:
new SWPrecacheWebpackPlugin(
{
cacheId: "static-cache",
filepath: __dirname + "/app/public/sw.js",
stripPrefix: __dirname + "/app/public/",
replacePrefix: "/",
staticFileGlobs: [
__dirname + "/app/public/dist/**/*.{js,html,css,eot,ttf,woff,woff2}",
__dirname + "/app/public/img/**/*.{png,jpg,gif,svg}",
__dirname + '/app/public/offline.html' /* here you can set offline urls*/
],
navigateFallback: __dirname + "/app/public/index.html"
}
)
