const {createProxyMiddleware} = require('http-proxy-middleware')
module.exports = function(app){
    app.use(
        '/api', 
        createProxyMiddleware(  //1.0.0 版本的援用形式官网规定 createProxyMiddleware
            { 
                target: 'http://127.0.0.1:5000', // 这里用 ip+ 端口
                changeOrigin: true,
                pathRewrite: { // 这里记得加上
                    "^/api": ""
                  }
            }
        )
