我正在使用 Angular 6 构建一个渐进式 Web 应用程序。

我已经使用 Angular CLI 生成了我的项目，然后使用ng add @angular/pwa.

我已经在 Github-Pages 上部署了我的项目。

Manifest 和 Service-Worker 被 Google Chrome 识别。我可以在主屏幕上安装我的应用程序并在线使用它。

    }
  ]
}

ngsw-config.json

{
  "index": "/index.html",
  "assetGroups": [
    {
      "name": "app",
      "installMode": "prefetch",
      "resources": {
        "files": [
          "/favicon.ico",
          "/index.html",
          "/*.css",
          "/*.js"
        ]
      }
    }, {
      "name": "assets",
      "installMode": "lazy",
      "updateMode": "prefetch",
      "resources": {
        "files": [
          "/assets/**"
        ]
      }
    }
  ]
}

问题是当我离线时，Service-Worker 不提供页面index.html和超时：

软件超时

但是，如果我/index.html在 URL 末尾添加（仍处于脱机状态），它会正确加载页面（并index.html从 URL 中删除，因此我无法再次成功刷新）

SW 加载 index.html

我在这里想念什么？谢谢你的帮助。
