node express 设置反向带理

var express = require('express');
var proxyMiddleWare = require("http-proxy-middleware");
var proxyPath = "http://localhost:3000";//目标后端服务地址(公司同事电脑地址)
var proxyOption ={target:proxyPath,changeOrigoin:true};
var app = express();
app.use(express.static("./public"));

app.use("/",proxyMiddleWare(proxyOption))//这里要注意"/discern" 是匹配的路由,它会将匹配的路由进行转发，没匹配到的就不会转发。('/discern'完全可以写成'/'就是说所有路由都可以访问)
app.listen(8888);
