React P68 npm运行脚手架启动项目后显示‘无法访问此网站’

将代码：

const proxy = require('http-proxy-middleware')module.exports = function(app){app.use(proxy('/api1',{ //遇见/api1前缀的请求，就会触发该代理配置target:'http://localhost:5000', //请求转发给谁changeOrigin:true,//控制服务器收到的请求头中Host的值pathRewrite:{'^/api1':''} //重写请求路径(必须)}))}

替换为

const {createProxyMiddleware } = require('http-proxy-middleware');module.exports = function(app) {app.use(createProxyMiddleware('/api1', { //api1是需要转发的请求(所有带有/api1前缀的请求都会转发给5000)target: 'http://localhost:5000', //配置转发目标地址(能返回数据的服务器地址)changeOrigin: true, //控制服务器接收到的请求头中host字段的值pathRewrite: {'^/api1': ''} //去除请求前缀，保证交给后台服务器的是正常请求地址(必须配置)}),createProxyMiddleware('/api2', { target: 'http://localhost:5001',changeOrigin: true,pathRewrite: {'^/api2': ''}}))}
