无论预缓存的数据如何，我每次离线时都需要显示一个自定义离线页面。

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

我尝试更改NavigationFallback为，offline.html但每次我在离线时重新加载页面时，它都会显示index.html页面并且不显示offline.html。

有人可以帮我添加自定义离线后备页面吗？

如果您指的是navigateFallback预缓存数据的属性，这里是有关如何使用它的文档：

sw-precache

navigateFallback [String] 设置 HTML 文档以用作在 sw-precache 缓存中找不到的 URL 的后备。此后备 URL 需要通过缓存，staticFileGlobs否则dynamicUrlToDependencies将无法正常工作。

// via staticFileGlobs
staticFileGlobs: ['/shell.html']
navigateFallback: '/shell.html'

// via dynamicUrlToDependencies
dynamicUrlToDependencies: {
  '/shell': ['/shell.hbs']
},
navigateFallback: '/shell'

这在与使用History API执行客户端 URL 路由的 Web 应用程序一起使用时会派上用场。它允许客户端生成的任意 URL 映射到备用缓存的 HTML 条目。理想情况下，此回退条目应用作能够根据请求 URL 在客户端加载适当资源的“应用程序外壳”。

注意：这不打算用于将失败的导航路由到通用的“离线后备”页面。无论浏览器在线还是离线，都使用 navigateFallback 页面。如果要实现“离线回退”，则使用类似于此示例的方法更合适。
