new WebpackDevServer(webpack(config), {
  hot:hot,
  inline: true,
  compress: true,
  //去掉真實ip的檢測
  disableHostCheck: true,
  stats: {
    chunks: false,
    children: false,
    colors: true
  },
  historyApiFallback: true,
  proxy: {
    ‘/api/**/*‘: {//接口開頭關鍵字 *表示全部
      target: ‘http://ip地址‘,
      //host: localPublicPath,
 

      changeOrigin: true,
      secure: false
    }
  }
})

就okle 

webpack代理解決跨域問題
