我有一个用于缓存图像的服务工作者,这个服务工作者只在前端模板中注册,但它仍然不断扩散到我的管理模板中。
这会导致我的表单在验证令牌受到影响时表现出不可预测的行为。
使用一些console.log,我认为在到达请求的页面之前触发了安装事件,但我无法确定那里的当前/下一个URL。
如何防止服务人员传播到管理面板并干扰页面?我只想缓存资产。
就相关而言,这是我的服务人员:
const PRECACHE = 'precache-v1.0.0';
const RUNTIME = 'runtime';
// A list of local resources we always want to be cached.
const PRECACHE_URLS = [
"public",
"media",
"unify",
];
importScripts('./cache-polyfill.js');
// The install handler takes care of precaching the resources we always need.
self.addEventListener('install', function(event) {
console.log('installing resources');
event.waitUntil(
caches.open(PRECACHE)
//.then(cache => cache.addAll(PRECACHE_URLS))
.then(self.skipWaiting())
);
});
// The activate handler takes care of cleaning up old caches.
self.addEventListener('activate', function(event) {
const currentCaches = [PRECACHE, RUNTIME];
event.waitUntil(
caches.keys().then(cacheNames => {
return cacheNames.filter(cacheName => !currentCaches.includes(cacheName));
}).then(cachesToDelete => {
return Promise.all(cachesToDelete.map(cacheToDelete => {
return caches.delete(cacheToDelete);
}));
}).then(() => self.clients.claim())
);
});
// The fetch handler serves responses for same-origin resources from a cache.
// If no response is found, it populates the runtime cache with the response
// from the network before returning it to the page.
self.addEventListener('fetch', event => {
// Skip cross-origin requests, like those for Google Analytics.
if (event.request.method === "GET") {
if (event.request.url.indexOf(PRECACHE_URLS) > -1) {
console.log("fetching " + event.request.url + " by the service worker");
event.respondWith(
caches.match(event.request).then(cachedResponse => {
if (cachedResponse) {
return cachedResponse;
}
return caches.open(RUNTIME).then(cache => {
return fetch(event.request).then(response => {
// Put a copy of the response in the runtime cache.
return cache.put(event.request, response.clone()).then(() => {
console.log('cached: ' + event.request.url);
return response;
});
});
});
})
);
}
else {
console.log("fetching " + event.request.url + " by service worker blocked, it's not a resource");
}
}
return fetch(event.request);
});
