在Chrome中使用Service Worker无法在脱机模式下呈现CSS

self.addEventListener('install', event => {
  event.waitUntil(
    caches.open('my-cache').then(cache => {
      return cache.addAll([
        '/',
        '/index.html',
        '/styles/main.css', // 确保 CSS 文件路径正确
        '/script/main.js'
      ]);
    })
  );
});

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

if ('serviceWorker' in navigator) {
  window.addEventListener('load', () => {
    navigator.serviceWorker.register('/service-worker.js').then(registration => {
      console.log('Service Worker registered with scope:', registration.scope);
    }).catch(error => {
      console.error('Service Worker registration failed:', error);
    });
  });
}

self.addEventListener('activate', event => {
  event.waitUntil(
    caches.keys().then(cacheNames => {
      return Promise.all(
        cacheNames.map(cacheName => {
          if (cacheName !== 'my-cache') {
            return caches.delete(cacheName);
          }
        })
      );
    })
  );
});
