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。

其他答案都添加代码到实时网站，以删除service worker。然而，我不想让这些活代码永远运行，所以我开发了一个解决方案，从service worker本身工作。步骤如下，我在我的博客上发布了更多的细节和解释。

删除注册service worker的代码。 将service worker脚本替换为以下文件。新代码必须从前一个service worker所在的相同URL中可用。如果您过去有多个service worker url，您应该在所有这些url上复制代码。

console.log("Cleanup Service Worker Starting");

caches.keys()
    .then(keys =>
        Promise.all(
            keys.map(async key => console.log("caches.delete", key, await caches.delete(key)))))
    .then(async () => {
        console.log("registration.unregister", await registration.unregister());
    })
    .then(() => console.log("DONE"))
    .catch(console.error);

这段代码相当直截了当。首先它删除所有缓存，然后注销自己。

用户的浏览器会在下次加载你的网站时自动检查更新的service worker，或者在最后一次service worker检查后24小时内自动检查下一个事件。这意味着现有用户将在下次访问时运行此清理。

如果你的服务人员不让你更新文件。你需要用下面的代码替换serviceworker文件(sw.js / serviceworker .js):

self.addEventListener('install', function(e) {
  self.skipWaiting();
});

self.addEventListener('activate', function(e) {
  self.registration.unregister()
    .then(function() {
      return self.clients.matchAll();
    })
    .then(function(clients) {
      clients.forEach(client => client.navigate(client.url))
    });
});

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);
          }
        });
      }

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);
      }),
    );
  });
}

以编程方式删除Service worker:

你可以像这样通过编程方式删除service worker:

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

文档:getRegistrations, unregister

通过用户界面移除Service worker

你也可以在Chrome Devtools的Application标签下删除service worker。
