PWA服务工作者在Angular中缓存

Question

我正在尝试在我的Angular应用中一起实现angular通用服务和service worker。我的问题是，当我部署更新时，它已经几天都没有更新。我仍然看到我的应用程序的旧视图。这是我在ngsw-config.json中所做的。我不能将maxAge放在assetGroups中。我只能将其放在dataGroups上，这就是为什么它仍呈现旧视图的原因？请启发我。

{
  "$schema": "./node_modules/@angular/service-worker/config/schema.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/**", "/*.(eot|svg|cur|jpg|png|webp|gif|otf|ttf|woff|woff2|ani)"]
      }
    }
  ],
  "dataGroups": [
    {
      "name": "caching api",
      "urls": ["backend-api/*"],
      "cacheConfig": {
        "maxSize": 100,
        "maxAge": "6h",
        "timeout": "10s",
        "strategy": "freshness"
      }
    }
  ]
}
