I am using as an environment, a Cloud9.io ubuntu VM Online IDE and I have reduced by troubleshooting this error to just running the app with Webpack dev server.我正在使用 Cloud9.io ubuntu VM Online IDE 作为环境,并且通过解决此错误,我已经减少到仅使用 Webpack 开发服务器运行应用程序。

I launch it with:我启动它:

webpack-dev-server -d --watch --history-api-fallback --host $IP --port $PORT

$IP is a variable that has the host address $PORT has the port number. $IP 是具有主机地址的变量 $PORT 具有端口号。

I am instructed to use these vars when deploying an app in Cloud 9, as they have the default IP and PORT info.我被指示在 Cloud 9 中部署应用程序时使用这些变量,因为它们具有默认 IP 和端口信息。

The server boots up and compiles the code, no problem, it is not showing me the index file though.服务器启动并编译代码,没问题,但它没有向我显示索引文件。 Only a blank screen with "Invalid Host header" as text.只有一个带有“无效主机标题”作为文本的空白屏幕。

This is the Request:这是请求:

This is the webpack.config.js:这是 webpack.config.js:

module.exports = {

  // Here the application starts executing

  output: {
    // options related to how webpack emits results

    path: path.resolve(__dirname, "./public"), // string
    // the target directory for all output files
    // must be an absolute path (use the Node.js path module)

    filename: "bundle.js", // string
    // the filename template for entry chunks

    publicPath: "/public/", // string
    // the url to the output directory resolved relative to the HTML page

  module: {
    // configuration regarding modules

    rules: [
      // rules for modules (configure loaders, parser options, etc.)
        test: /\.jsx?$/,
        include: [
          path.resolve(__dirname, "./app")
        exclude: [
          path.resolve(__dirname, "./node_modules")
        loader: "babel-loader?presets[]=react,presets[]=es2015,presets[]=stage-0",
        // the loader which should be applied, it'll be resolved relative to the context
        // -loader suffix is no longer optional in webpack2 for clarity reasons
        // see webpack 1 upgrade guide
        test: /\.css$/,
        use: [ 'style-loader', 'css-loader' ]
        test: /\.(png|jpg|jpeg|gif|svg|eot|ttf|woff|woff2)$/,
        loader: 'url-loader',
        options: {
          limit: 10000

  devServer: {
    compress: true

Webpack dev server is returning this because of my host setup.由于我的主机设置,Webpack 开发服务器正在返回此信息。 In webpack-dev-server/lib/Server.js line 60. From https://github.com/webpack/webpack-dev-server在 webpack-dev-server/lib/Server.js 第 60 行。来自https://github.com/webpack/webpack-dev-server

My question is how do I setup to correctly pass this check.我的问题是如何设置才能正确通过此检查。 Any help would be greatly appreciated.任何帮助将不胜感激。
