我在Cloud9.io上的Webpack开发服务器中运行我的React应用程序时收到“Invalid Host header”消息

我使用的是一个环境,一个Cloud9.io ubuntu VM Online IDE,我通过对此错误进行故障排除,只是通过Webpack dev服务器运行应用程序 .

我推出它:

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

$ IP是一个变量,其主机地址为$ PORT,具有端口号 .

在Cloud 9中部署应用程序时,我被指示使用这些变量,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,但它没有向我显示索引文件 . 只有一个空白屏幕,"Invalid Host header"为文本 .

这是请求:

GET / HTTP/1.1
Host: store-client-nestroia1.c9users.io
Connection: keep-alive
Pragma: no-cache
Cache-Control: no-cache

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

  devServer: {
    compress: true
  }
}

由于我的主机设置,Webpack dev服务器正在返回此状态 . 在webpack-dev-server / lib / Server.js第60行 . 来自https://github.com/webpack/webpack-dev-server

我的问题是我如何设置正确通过此检查 . 任何帮助将不胜感激 .

    我用这个解决了,因为webpack-dev-server 2.4.4添加了主机检查

    devServer: {
    
        compress: true,
    
        disableHostCheck: true,   // That solved it
    
     }
    

    编辑:请注意,此修复程序是不安全的 .

    我发现,我需要将devServer的 public 属性设置为我的请求的主机值 . 因为它将显示在该外部地址 .

    所以我在webpack.config.js中需要这个

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

    另一种解决方案是在CLI上使用它:

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

    这对我有用:

    在webpack.config.js中的devServer下添加allowedHosts:

    devServer: {
      compress: true,
      inline: true,
      port: '8080',
      allowedHosts: [
          '.amazonaws.com'
      ]
    },
    

    我不需要使用--host或--public params .

    使用webpack-dev-server时,将此配置添加到webpack配置文件中(您仍然可以将主机指定为0.0.0.0) .

    devServer: {
        disableHostCheck: true,
        host: '0.0.0.0',
        port: 3000
    }

    如果您在C9上使用create-react-app,只需运行此命令即可启动

    npm run start --public $C9_HOSTNAME
    

    并从您的主机名访问应用程序(例如,在终端输入 $C_HOSTNAME 以获取主机名)
