Angular 7 PWA-脱机模式下缺少字体超棒图标

问题是在脱机模式下，字体图标不会显示。 在脱机模式下，我可以看到“网络”选项卡中状态为“失败”的文件

在dist文件夹中生成&

在应用程序选项卡的缓存中-例如/fa-solid-900.fb493903265cad425ccd.woff2

非常感谢您的帮助。详情如下-提前感谢

在ngsw-config.json-

"/favicon.ico",
      "/index.html",
      "/*.css",
      "/*.js",
      "/*.woff",
      "/*.woff2",
      "/*.ttf",
      "/fontawesome-webfont*"
    ]

Manifest.json-

  "short_name": "TALSWeb",
  "theme_color": "#00A160",
  "background_color": "#fafafa",
  "display": "standalone",
  "scope": "/",
  "start_url": "/",

生成的ngsw.json文件摘录了-

"assetGroups": [
    {
      "name": "app",
      "installMode": "prefetch",
      "updateMode": "prefetch",

在ngsw-config.json文件中，您必须在assetGroup内输入css文件的整个cdn url/目录路径

所以它可以在第一次加载时缓存。

对我来说，问题是FA查询中有版本号，因此它导致workbox不缓存它，因为它认为它是另一个资源

因此，需要设置ignoreURLParametersMatching参数，文档中的更多信息：

这是我的配置：

"name": "assets",
  "installMode": "lazy",
  "updateMode": "prefetch",
  "resources": {
    "files": [
      "/assets/**",
      "/*.(eot|svg|cur|jpg|png|webp|gif|otf|ttf|woff|woff2|ani)",
      "/*-es5*.js"
    ],
    "urls": [
      "https://fonts.googleapis.com/**"
    ]
  }
