我需要使用manifest.json添加提示以添加到主屏幕,但是当我在审核中的pwa分数为100%时,它不会显示
我有如下所示的dist文件夹:-
我的清单json包含以下内容:-
{
"name": "xyz",
"short_name": "xyz",
"icons": [
{
"src": "/xyz/static/img/icons/xy-icon-192x192.png",
"sizes": "192x192",
"type": "image/png"
},
{
"src": "/xyz/static/img/icons/xy-icon-512x512.png",
"sizes": "512x512",
"type": "image/png"
}
],
"start_url": "xyz/index.html",
"scope": ".",
"display": "standalone",
"background_color": "#0628b9",
"theme_color": "#000000"
}
我正在为服务工作者使用Workbox插件,我也尝试过与普通服务工作者一起使用,如下所示:-
sw.js
var VERSION = '20';
self.addEventListener('install', function(e) {
e.waitUntil(caches.open(VERSION).then(cache => {
return cache.addAll([
'https://cfjedimaster.github.io/nomanssky/client/index.html'
]);
}))
});
self.addEventListener('fetch', function(e) {
var tryInCachesFirst = caches.open(VERSION).then(cache => {
return cache.match(e.request).then(response => {
if (!response) {
return handleNoCacheMatch(e);
}
// Update cache record in the background
fetchFromNetworkAndCache(e);
// Reply with stale data
return response
});
});
e.respondWith(tryInCachesFirst);
});
self.addEventListener('activate', function(e) {
e.waitUntil(caches.keys().then(keys => {
return Promise.all(keys.map(key => {
if (key !== VERSION)
return caches.delete(key);
}));
}));
});
function fetchFromNetworkAndCache(e) {
// DevTools opening will trigger these o-i-c requests, which this SW can't handle.
// There's probaly more going on here, but I'd rather just ignore this problem. :)
// https://github.com/paulirish/caltrainschedule.io/issues/49
if (e.request.cache === 'only-if-cached' && e.request.mode !== 'same-origin') return;
return fetch(e.request).then(res => {
// foreign requests may be res.type === 'opaque' and missing a url
if (!res.url) return res;
// regardless, we don't want to cache other origin's assets
if (new URL(res.url).origin !== location.origin) return res;
return caches.open(VERSION).then(cache => {
// TODO: figure out if the content is new and therefore the page needs a reload.
cache.put(e.request, res.clone());
return res;
});
}).catch(err => console.error(e.request.url, err));
}
function handleNoCacheMatch(e) {
return fetchFromNetworkAndCache(e);
}
但是我看不到提示添加到主屏幕。
答案 0 :(得分:2)
在测试/调试A2HS时,大部分工作是清除以前的测试和安装。
一遍又一遍。
浏览器会特意记住上次执行的操作,因此不会困扰用户安装提示。
如果您想再次看到提示,可能需要完全清除缓存。
如果您对以前的提示说“否”,则它将在XX个月内不再询问。 如果已经安装,则不再询问。
要寻找的一些东西
-在台式机Chrome浏览器中
-从chrome:// apps /
删除图标
-如果不起作用,则可能需要清除缓存
