对我来说，我只是用一个新的不存在的scope service worker来代替旧的scope service worker，

ServiceWorker: {
        events: true,
        // what range of URLs a service worker can control. Use a nonexistent path to disable ServiceWorker
        scope: '/disable-service-worker/',
      },

对于app.js，我添加了以下代码来注销旧的sw:

if ('serviceWorker' in navigator) {
  navigator.serviceWorker.getRegistrations().then(registrations => {
    for (const registration of registrations) {
      // keep only serviceWorker which scope is /disable-service-worker/, The purpose is to make serviceWorker useless
      if (registration.scope.includes('/disable-service-worker/') === false) {
        registration.unregister()
      }
    }
  });
  // clear cache of service worker
  caches.keys().then(keyList => {
    return Promise.all(
      keyList.map(key => {
        return caches.delete(key);
      }),
    );
  });
}

如果您想在浏览器中注销所有已注册的service worker， 你可以通过打开前任来做到。

铬:Chrome: / / serviceworker-internals / 勇敢勇敢:/ / serviceworker-internals /

打开DevTools >控制台，粘贴如下:

$$('.unregister').forEach(b => b.click())

安全卸载Service Worker

if ('serviceWorker' in navigator) {
      navigator.serviceWorker.getRegistrations().then(function (registrations) {
        for (const registration of registrations) {
          // unregister service worker
          console.log('serviceWorker unregistered');
          registration.unregister();
        }
      });
    }

仅供参考，如果你使用的是MacOS Safari浏览器，有一种方法可以强制注销service worker (Safari 12.1的步骤和图片):

Safari >首选项…>隐私>管理网站数据… 输入域名(例如。'localhost')，点击“删除”

注意:除了service worker之外，这还将删除该域的所有缓存、cookie和数据库。

此代码与Internet Explorer兼容:

if (navigator.serviceWorker) {
    navigator.serviceWorker.getRegistrations().then(                
        function(registrations) {
            for (let idx in registrations) {
                registrations[idx].unregister()
            }
        })
}

IE不支持'for…and的意思是…的“构造可能导致”“SCRIPT1004: Expected”错误

检测service worker:

navigator.serviceWorker.controller

删除service worker的代码:

navigator.serviceWorker.getRegistrations()
  .then(registrations => {
    registrations.forEach(registration => {
      registration.unregister();
    })
  });

  navigator.serviceWorker.getRegistrations().then(function(registrations) {
   for(let registration of registrations) {
    registration.unregister()
  } })

  if(window.navigator && navigator.serviceWorker) {
    navigator.serviceWorker.getRegistrations()
    .then(function(registrations) {
      for(let registration of registrations) {
        registration.unregister();
      }
    });
  }

  if ('caches' in window) {
      caches.keys()
        .then(function(keyList) {
            return Promise.all(keyList.map(function(key) {
                return caches.delete(key);
            }));
        })
  }

  if ('serviceWorker' in navigator) {
        navigator.serviceWorker.getRegistrations().then(function (registrations) {
          for (const registration of registrations) {
            // unregister service worker
            console.log('serviceWorker unregistered');
            registration.unregister();

            setTimeout(function(){
              console.log('trying redirect do');
              window.location.replace(window.location.href); // because without redirecting, first time on page load: still service worker will be available
            }, 3000);
          }
        });
      }
