没有与service-worker.js匹配的路由

Question

我生成了rails应用程序，并得到了开箱即用的消息。我不知道service-worker.js是什么，但我认为它可以与一些默认的gem捆绑在一起？

Answer 1

我假设它来自另一个使用webworker的应用程序。如果您使用的是Firefox，请转到菜单>网络开发人员>服务工作者，然后从那里注销网络工作者(这是一种方法(。如果需要，另一个应用程序将再次注册它。

Answer 2

这来自客户端，因此它来自已在浏览器中注册的服务工作者。

打开DevTools并在控制台中运行navigator.serviceWorker.getRegistration().then(r => r.unregister())以禁用它。

Answer 3

我用这个gem解决了同样的问题。

1( 将gem 'serviceworker-rails'添加到Gemfile

2( 在控制台中运行bundle install

3( 在控制台中运行rails g serviceworker:install

4( 将match '/offline.html'字符串添加到config/ininitializers/serviceworker.rb

5( 创建文件(即使为空也足够了(public/online.html

就是这样。经过这些步骤后，错误信息消失了。
