需要webpack，webpack-dev-server
npm install webapck webpack-dev-server --save-dev
设置时
devServer: { historyApiFallback: true, hot: true, inline: true, stats: { colors: true }, proxy: { ‘/list‘: { target: ‘https://api.github.com‘, pathRewrite: {‘^/column‘ : ‘/column‘}, changeOrigin: true } } },
这段代码就是将 ‘/list‘ 通过本地开发服务器webpack-dev-server转发到 ‘https://api.github.com‘
