Question

问题在于，在离线模式下，字体真棒图标无法显示。在离线模式下，我可以在“网络”标签中看到状态为失败的文件

在dist文件夹中生成，并且
在“应用程序”标签中的缓存中-例如/fa-solid-900.fb493903265cad425ccd.woff2

对此非常感谢。下面的详细信息-预先感谢。

in offline mode missing files are in the cache.PNG

Answer 1

在ngsw-config.json文件中，您必须在assetGroup中输入fontawesome css文件的整个CDN url /目录路径。

以便可以在第一次加载时将其缓存。

Answer 2

对我来说，问题在于FA查询中存在版本号，因此导致工作箱无法缓存它，因为它认为它是另一种资源。

因此，需要设置ignoreURLParametersMatching参数，有关更多信息，请参见文档：https://developers.google.com/web/tools/workbox/modules/workbox-precaching#ignore_url_parameters

Answer 3

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/**"
    ]
  }
