Question

无论何时预缓存数据，每次离线时我都需要显示一个定制脱机页面。

我正在使用create-react-app和workbox-webpack-plugin

我尝试将NavigationFallback更改为offline.html，但是每次脱机时重新加载页面时，它都会显示index.html页面，而不显示offline.html。

有人可以帮我添加自定义的离线后备页面吗？

如果您要引用navigateFallback属性来预缓存数据，则以下是有关如何使用它的文档：

sw-precache

navigateFallback [String]设置HTML文档以用作后备在sw-precache缓存中找不到URL。此后备网址需要通过staticFileGlobs或dynamicUrlToDependencies进行缓存它不起作用。
// via staticFileGlobs
staticFileGlobs: ['/shell.html']
navigateFallback: '/shell.html'

// via dynamicUrlToDependencies
dynamicUrlToDependencies: {
  '/shell': ['/shell.hbs']
},
navigateFallback: '/shell'
与执行以下操作的Web应用程序一起使用时，这非常方便   使用History API进行客户端URL路由。它允许任意   客户端生成以映射到后备缓存HTML条目的URL。   理想情况下，此后备条目应作为“应用程序外壳”   能够基于客户端加载适当的资源   请求网址。

注意：这不是用来将失败的导航路由到   通用的“离线后备”页面。使用了navigationFallback页面   浏览器是在线还是离线。如果您想实施   “离线后备”，然后使用类似于此example的方法   更合适。
