如何修改Workbox生成的预缓存清单文件？需要网址前面有'/'

Question

在生成的precache-manifest.*.js文件中，当我需要绝对路径时，所有URL都引用相对路径，因为我的应用程序还将包含一些子目录。

生成文件的示例：

self.__precacheManifest = (self.__precacheManifest || []).concat([
  {
    "revision": "1d94d834b7044ec6d4e9",
    "url": "js/app.js"
  },
  {
    "revision": "632f09e6ed606bbed1f1",
    "url": "css/app.css"
  },
  ...
}

当我需要它看起来像这样时：

self.__precacheManifest = (self.__precacheManifest || []).concat([
  {
    "revision": "1d94d834b7044ec6d4e9",
    "url": "/js/app.js"
  },
  {
    "revision": "632f09e6ed606bbed1f1",
    "url": "/css/app.css"
  },
  ...
}

我正在使用webpack 4.41.0和workbox-webpack-plugin 4.3.1

任何帮助将不胜感激！如果需要，我也可以添加更多详细信息。

这是我的webpack配置：

let config = {
  entry,

  stats: {
    hash: false,
    version: false,
    timings: false,
    children: false,
    errorDetails: false,
    entrypoints: false,
    performance: inProduction,
    chunks: false,
    modules: false,
    reasons: false,
    source: false,
    publicPath: false,
    builtAt: false
  },

  performance: { hints: false },

  // Valid options: "production" | "development" | "none"
  mode: inProduction ? 'production' : 'development',

  plugins: [
    new CopyPlugin(copyConfig),
    new webpack.ProvidePlugin(providers), // Providers, e.g. jQuery
    new WebpackNotifierPlugin({ title: 'Webpack' }), // OS notification
    new VueLoaderPlugin(), // Vue-loader
    new CleanWebpackPlugin(pathsToClean, cleanOptions), // Clean up pre-compile time
    new ManifestPlugin(manifestOptions), // Manifest file
    new FriendlyErrorsWebpackPlugin({ clearConsole: true }), // Prettify console
    new MiniCssExtractPlugin(cssOptions), // Extract CSS files
    new WebpackMd5Hash(), // use md5 for hashing
    {
      /* Laravel Spark RTL support */
      apply: (compiler) => {
        compiler.hooks.afterEmit.tap('AfterEmitPlugin', (compilation) => {
          exec('node_modules/rtlcss/bin/rtlcss.js public/css/app-rtl.css ./public/css/app-rtl.css', (err, stdout, stderr) => {
            if (stdout) process.stdout.write(stdout);
            if (stderr) process.stderr.write(stderr);
          });
        });
      }
    }
  ],

  module: {
    rules: [
      {
        test: /\.vue$/,
        use: ['vue-loader']
      },
      {
        test: /\.s?css$/,
        use: [
          'style-loader',
          {
            loader: MiniCssExtractPlugin.loader,
            options: { hmr: isHot } // set HMR if flagged
          },
          'css-loader',
          'postcss-loader',
          'sass-loader'
        ]
      }
    ]
  },

  resolve: {
    extensions: ['.js', '.json', '.vue'],
    modules: ['node_modules'],
    alias: {
      'vue$': 'vue/dist/vue.esm.js',
      '~': path.join(__dirname, 'resources/assets/js'),
      jquery: "jquery/src/jquery",
    }
  },

  output: {
    filename: 'js/[name].js',
    // chunkFilename: inProduction ? 'js/[name].[chunkhash].js' : 'js/[name].js',
    path: publicPath,
  },

  optimization: {
    ...optimization,
    concatenateModules: false,
    providedExports: false,
    usedExports: false,
  },

  devtool: inDevelopment ? 'eval-source-map' : false,

  devServer: {
    headers: {
      'Access-Control-Allow-Origin': '*'
    },
    port: port,
    contentBase: publicPath,
    historyApiFallback: true,
    noInfo: false,
    compress: true,
    quiet: true,
    hot: isHot,
  }
}

和我的GenerateSW：

new GenerateSW({
    // The cache ID
    cacheId: 'pwa',

    // The path and filename of the service worker file that will be created by the build process, relative to the webpack output directory.
    swDest: path.join(publicPath, 'sw.js'),

    clientsClaim: true,
    skipWaiting: true,

    // Files to exclude from the precache
    exclude: [/\.(?:png|jpg|jpeg|svg)$/, /\.map$/, /manifest\.json$/, /service-worker\.js$/, /sw\.js$/],

    // Default fall-back url
    navigateFallback: '/',

    // An optional array of regular expressions that restricts which URLs the configured navigateFallback behavior applies to.
    // This is useful if only a subset of your site's URLs should be treated as being part of a Single Page App.
    navigateFallbackWhitelist: [
      /^\/media\//,
      /^\/settings\//,
    ],

    // Runtime cache
    runtimeCaching: [
      {
        urlPattern: new RegExp(`${process.env.APP_URL}`),
        handler: 'NetworkFirst',
        options: {
          cacheName: `${process.env.APP_NAME}-${process.env.APP_ENV}`
        }
      },
      {
        urlPattern: new RegExp('https://fonts.(googleapis|gstatic).com'),
        handler: 'CacheFirst',
        options: {
          cacheName: 'google-fonts'
        }
      }
    ]
  }
)

以及几个定义的公共变量：

...
// Production flag
const inProduction = process.env.NODE_ENV === 'production'
const inDevelopment = process.env.NODE_ENV === 'development'

// HMR
const isHot = process.argv.includes('--hot')

// Public/webroot path
const publicPath = path.resolve(__dirname, 'public')

// Primary webpack entry point(s)
const entry = {
  /*
   * JS entry point/Vue base component
   * Make sure to import your css files here, e.g. `import '../sass/app.scss'`
   */
  app: path.resolve(__dirname, 'resources/assets/js/app.js'),
}
...

对于访问此问题的任何人，您都可以使用webpack output.publicPath设置为清单URL添加前缀，如下所示：

plugins: [
    new InjectManifest({}) // Left here just for reference
],
output: {
    publicPath: '/' // You can add your prefix here
}
