[英]No matching service worker detected even though I have a service worker and my PWA is working fine
我一直在研究一個用 HTML、CSS 和 JS 編寫的項目,並在屏幕上隨機顯示不同的視頻。 我希望它成為 PWA,所以它做到了。 它工作得很好,但是當我打開 Chrome DevTools 和“應用程序”頁面時,在“清單”部分它會發出警告:“沒有檢測到匹配的服務工作者。您可能需要重新加載頁面,或檢查服務工作者是否為當前頁面還控制清單中的起始 URL。”
我對服務工作者知之甚少,我想知道它為什么有效,但似乎沒有。 另一個問題是我從來沒有彈出“添加到主屏幕”。 但是如果我手動添加它,它就完美無缺。 它也可以離線使用。

我的 main.js 中的 Service Worker 代碼:
window.addEventListener("load", () => {
registerSW();
});
async function registerSW() {
if ('serviceWorker' in navigator) {
try {
await navigator.serviceWorker.register('./sw.js');
} catch (e) {
console.log(`SW registration failed`);
}
}
}
我的 sw.js:
//CACHING FILES//
const filesToCache = [
'./',
'./offline.html',
'./css/offline.css',
];
const staticCacheName = 'pages-cache-v2';
self.addEventListener('install', event => {
console.log('Attempting to install service worker and cache static assets');
event.waitUntil(
caches.open(staticCacheName)
.then(cache => {
return cache.addAll(filesToCache);
})
);
});
//LOADING FILES WHEN OFFLINE//
self.addEventListener('fetch', event => {
console.log('Fetch event for ', event.request.url);
event.respondWith(
caches.match(event.request)
.then(response => {
if (response) {
console.log('Found ', event.request.url, ' in cache');
return response;
}
console.log('Network request for ', event.request.url);
return fetch(event.request)
.then(response => {
// TODO 5 - Respond with custom 404 page
return caches.open(staticCacheName).then(cache => {
cache.put(event.request.url, response.clone());
return response;
});
});
}).catch(error => {
console.log('Error, ', error);
return caches.match('./offline.html');
})
);
});
// TODO 6 - Respond with custom offline page
self.addEventListener('activate', event => {
console.log('Activating new service worker...');
const cacheWhitelist = [staticCacheName];
event.waitUntil(
caches.keys().then(cacheNames => {
return Promise.all(
cacheNames.map(cacheName => {
if (cacheWhitelist.indexOf(cacheName) === -1) {
return caches.delete(cacheName);
}
})
);
})
);
});

解決方案是我沒有使manifest.json 中的scope
和start_url
相同,這需要是網站地址。 所以我把代碼改成:
"start_url": "https://ondersumer07.github.io/vinematik/",
"background_color": "#00adb5",
"display": "standalone",
"scope": "https://ondersumer07.github.io/vinematik/",
"theme_color": "#00adb5"
問題就解決了。
