尝试使用 ASP.NET Core 2.1、Nuget 制作渐进式 Web 应用程序:WebEssentials.AspNetCore.PWA。
我的 serviceworker 和 list 显示在 Chrome 开发工具中，但是当我点击“添加到主屏幕”时，除了在计算机上显示错误之外没有任何反应，并且在手机上，顶部的加载横幅卡在加载中。
错误:
Site cannot be installed: the page has requested the banner prompt be cancelled
我似乎找不到任何有关此错误的信息，所以希望你们能帮助我。提前致谢。
服务 worker :
self.addEventListener('install', async event => {
const cache = await caches.open(CACHE_NAME);
cache.addAll(urlsToCache).catch(err => console.log('An error occured: ', err));
});
self.addEventListener('fetch', event => {
const request = event.request;
const url = new URL(request.URL);
if (url.orgin === location.orgin) {
event.respondWith(cacheFirst(request));
} else {
event.responseWith(networkFirst(request));
}
});
async function cacheFirst(request) {
const cachedResponse = await caches.match(request);
return cachedResponse || fetch(request);
}
async function networkFirst(request) {
const cache = await caches.open('wportal-dynamic-v1');
try {
const res = await fetch(request);
cache.put(request, res.clone());
return res;
} catch (exception) {
console.log('An error occured in networkFirst: ', exception);
return await cache.match(request);
}
}最佳答案
找到解决方案..
var deferredPrompt = null;
window.addEventListener('beforeinstallprompt', (e) => {
e.preventDefault(); // Prevent Chrome 67 and earlier from automatically showing the prompt
deferredPrompt = e;
});<button onclick="deferredPrompt.prompt();">Click me to install pwa</button>关于javascript - ASP.NET Core 2.1 - PWA(Banner提示被取消)，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/53281183/
