解决 vue-cli 2 中 webpack-dev-serveri 启动后通过外部访问报错 invalid host header

修改 config/index.js 的 host 属性为 ‘0.0.0.0’

{
// ...,
host: '0.0.0.0',
port: 8080,
// ...
}

修改 build/webpack.dev.conf.js 的 devServer 配置

增加 disableHostCheck = true

devServer: {
    clientLogLevel: 'warning',
    historyApiFallback: true,
    hot: true,
    compress: true,
    host: HOST || config.dev.host,
    port: PORT || config.dev.port,
    open: config.dev.autoOpenBrowser,
    overlay: config.dev.errorOverlay
      ? { warnings: false, errors: true }
      : false,
    publicPath: config.dev.assetsPublicPath,
    proxy: config.dev.proxyTable,
    quiet: true, // necessary for FriendlyErrorsPlugin
    disableHostCheck: true,
    watchOptions: {
      poll: config.dev.poll,
    }
  }

启动后就可以通过 IP 访问了，比如 IP 为 192.168.1.100

http://192.168.1.100:8080
