在Cloud9.io上的Webpack开发服务器中运行我的React应用程序时，出现“无效的主机标头”消息

Question

我正在使用Cloud9.io ubuntu VM Online
IDE作为环境，并且通过对该错误进行故障排除而减少了使用Webpack开发服务器运行应用程序的速度。

我用以下命令启动它：

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

$ IP是具有主机地址的变量，$ PORT具有端口号。

我被指示在Cloud 9中部署应用程序时使用这些var，因为它们具有默认的IP和PORT信息。

服务器启动并编译代码，没问题，虽然它 没有 显示索引文件。只有空白屏幕，“无效的主机头”为文本。

这是请求：

GET / HTTP/1.1
Host: store-client-nestroia1.c9users.io
Connection: keep-alive

这是我的package.json：

}

这是webpack.config.js：

const path = require('path');

module.exports = {

  entry: ['whatwg-fetch', "./app/_app.jsx"], // string | object | array
  // Here the application starts executing
  // and webpack starts bundling
  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?$/,

        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开发服务器由于我的主机设置而返回此消息。在webpack-dev-server / lib /
Server.js第60行中。来自https://github.com/webpack/webpack-dev-
server

我的问题是如何设置才能正确通过此检查。任何帮助将不胜感激。

Answer 1

我发现，需要将publicdevServer 的属性设置为请求的主机值。由于它会显示在该外部地址。

所以我需要在我的webpack.config.js中

devServer: {
  compress: true,
  public: 'store-client-nestroia1.c9users.io' // That solved it
}

另一个解决方案是在CLI上使用它：

webpack-dev-server –public $ C9_HOSTNAME <-用于Cloud9外部IP的var
