Question

我想使用Javascript将文件上传到Firebase的Google云端存储。问题是我正在使用npm run dev在本地服务器上测试它，显然这不允许我将文件上传到FB存储位置（看起来像gs://xyz.appspot.com），因为交叉原始请求阻止。

所以，根据this recommendation，我现在正在尝试使用Node的http-server模块建立一个http服务器。我的项目由Webpack生成，输出文件位于dist。在dist内我运行http-server index.html，我看到了：

Starting up http-server, serving index.html
Available on:
  http://127.0.0.1:8080
  http://192.XXX:8080
Hit CTRL-C to stop the server
[Fri May 05 2017 08:23:37 GMT+0200 (CEST)] "GET /__webpack_hmr" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_11_6) xAppleWebKit/537.36 (KHTML, like Gecko) Chrome/56.0.2924.87 Safari/537.36"
[Fri May 05 2017 08:23:37 GMT+0200 (CEST)] "GET /__webpack_hmr" Error (404): "Not found"

最后两条消息不断重复。

我转到localhost地址，找不到页面（404错误）。任何想法我的节点服务器出了什么问题？

编辑：

实际上，http-server采用了要提供的文件的路径，所以我应该一直在使用：

http-server ./

这是webpack配置：

var path = require('path')

module.exports = {
  build: {
    env: require('./prod.env'),
    index: path.resolve(__dirname, '../dist/index.html'),
    assetsRoot: path.resolve(__dirname, '../dist'),
    assetsSubDirectory: 'static',
    assetsPublicPath: '/',
    productionSourceMap: true,
    // Gzip off by default as many popular static hosts such as
    // Surge or Netlify already gzip all static assets for you.
    // Before setting to `true`, make sure to:
    // npm install --save-dev compression-webpack-plugin
    productionGzip: false,
    productionGzipExtensions: ['js', 'css'],
    // Run the build command with an extra argument to
    // View the bundle analyzer report after build finishes:
    // `npm run build --report`
    // Set to `true` or `false` to always turn it on or off
    bundleAnalyzerReport: process.env.npm_config_report
  },
  dev: {
    env: require('./dev.env'),
    port: 8080,
    autoOpenBrowser: true,
    assetsSubDirectory: 'static',
    assetsPublicPath: '/',
    proxyTable: {},
    // CSS Sourcemaps off by default because relative paths are "buggy"
    // with this option, according to the CSS-Loader README
    // (https://github.com/webpack/css-loader#sourcemaps)
    // In our experience, they generally work as expected,
    // just be aware of this issue when enabling this option.
    cssSourceMap: false
  }
}

此仍然无法解决我的问题。页面加载，但我得到相同的跨源错误。

通过使用Node的http-server模块
