推荐答案

答案在下面.但是把它放在像 sw.js 一样运行 service worker 的 main.js 中是非常重要的.Service Worker 注册后

the answer is in below. but it is very important to put it in the main.js that runs service worker like sw.js. after regissteration of service worker

if ('serviceWorker' in navigator) {
   navigator.serviceWorker.register('/sw.js')
} else {
    console.log('CLIENT: service worker is not supported.');
}

这段代码----->

var deferredPrompt;
self.addEventListener('beforeinstallprompt', function (e) {
      console.log('beforeinstallprompt Event fired');
      e.preventDefault();
      deferredPrompt = e.originalEvent;
      return false;
});
