javascript - 渐进式 Web 应用程序 - Service Worker 不提供 start_URL

Question

正在玩渐进式网络应用程序。我试图让网络应用安装横幅工作，但我一直收到 service worker does not successfully serve the manifest's start_url在我使用 Lighthouse 调试之后(下图)。目前我正在使用 azure 托管我的网站。

新:
我检查了我所有的缓存、start_url 以及我的服务人员，以查看所有内容是否匹配。但它仍然给我同样的错误。



我不确定是不是我的 start_url或我的service-worker问题。下面是我的代码。
manifest.json

  {
   "short_name": "MY EXPERTS",
   "name": "MYEXPERT",
   "icons": [
    {
      "src": "Images/petronas_logo_192.png",
      "type": "image/png",
      "sizes": "192x192"
    },
    {
      "src": "Images/petronas_logo_192.png",
      "type": "image/png",
      "sizes": "512x512"
    }
 ],

 "background_color": "#FFFFFF",
 "theme_color": "#67BCFF",
 "display": "standalone",
 "start_url": "/Home/Index"
}

AddServiceWorker.js

if ('serviceWorker' in navigator) {
navigator.serviceWorker.register('/service-worker.js').
    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);
    });
}

service-worker.js

 self.addEventListener('install', e => {
 e.waitUntil(
    caches.open('airhorner').then(cache => {
        return cache.addAll([
            '/',
            '/?utm_source=homescreen',
            '/Home/About',
            '/Home/Index',
            '/Home/Contact'
        ])
            .then(() => self.skipWaiting());
    })
  )
});

self.addEventListener('activate', event => {
 event.waitUntil(self.clients.claim());
});

self.addEventListener('fetch', event => {
  event.respondWith(
    caches.match(event.request).then(response => {
        return response || fetch(event.request);
    })
  );
});

Answer 1

来自 Register A service worker ,

If we register the service worker file at /example/sw.js, then the service worker would only see fetch events for pages whose URL starts with /example/ (i.e. /example/page1/, /example/page2/).

内联显示的错误并在此 documentation 中给出，请检查以下内容:

1. Define a start_url property in your manifest.json file.
2. Ensure that your service worker properly caches a resource that matches the value of start_url.

另外，请查看 tutorial看看它是否会帮助你。
