大家好,我刚接触这项技术,希望能请教一下我的代码问题。我的目标是将资源文件缓存,并从服务工作者返回。
以下是我用来注册服务工作者的代码:
if ('serviceWorker' in navigator) {
navigator.serviceWorker.register('/serviceworker.js')
.then(function(reg) {
// registration worked
console.log('Registration succeeded. Scope is ' + reg.scope);
}).catch(function(error) {
// registration failed
console.log('Registration failed with ' + error);
});
}
以下是 Service Worker 中的代码
importScripts('/cache-poli.js');
var CACHE_VERSION = 'app-v2';
var CACHE_FILES = [
'/',
'/js/plugins/bootstrap/js/bootstrap.min.js',
'/js/plugins/bootstrap-select/bootstrap-select.min.js',
'/js/plugins/prettyphoto/js/jquery.prettyPhoto.js',
'/js/plugins/jquery.sticky.min.js',
'/js/plugins/jquery.easing.min.js',

];
self.addEventListener('install', function (event) {
event.waitUntil(
caches.open(CACHE_VERSION)
.then(function (cache) {
console.log('Opened cache');
return cache.addAll(CACHE_FILES);
})
);
});
self.addEventListener('activate', function (event) {
event.waitUntil(
caches.keys().then(function(keys){
return Promise.all(keys.map(function(key, i){
if(key !== CACHE_VERSION){
return caches.delete(keys[i]);
}
}))
})
)
});
self.addEventListener('fetch', function (event) {
event.respondWith(
caches.open(CACHE_VERSION).then(function(cache){
caches.match(event.request).then(function(response) {
return response || fetch(event.request);
})
})
)
});
我正在使用Google Chrome开发工具查看安装过程,一切都已缓存,并且服务工作者没有显示任何错误,但是当我再次尝试访问该网站时,它会给我一个错误信息。
此网站无法访问。 网页“domain.com”可能暂时无法访问,或者已永久移动到新的 Web 地址。
