最近，不赶着做项目，于是想着怎样做公司的前后端分离，这个时候想到了nodejs，于是打算今天做一个代理的demo，其实代码很简单，但是一直卡在一个地方，现在问题解决了，贴上代码和截图。

localhost:3000服务端的代码
const express = require(‘express‘);
const proxy = require(‘http-proxy-middleware‘);
const app = express();
app.use(express.static(‘public‘));
//app.use(express.static(‘client‘));
// Add middleware for http proxying
const apiProxy = proxy(‘/api‘, { target: ‘http://localhost:8080‘,changeOrigin: true });
app.use(‘/api/*‘, apiProxy);
// Render your site
app.get(‘/index.htm‘, function(req,res){
res.sendFile(__dirname+‘/src/index.html‘);
});
app.listen(3000, () => {
console.log(‘Listening on: http://localhost:3000‘);
});
localhost:8080服务上的代码
var express = require(‘express‘);
var app = express();
app.use(express.static(‘public‘));
var server = app.listen(8080,function(){
var host = server.address().address;
var port = server.address().port;
console.log(‘应用实例，访问地址为 http://%s:%s‘,host,port);
})
app.get(‘/api/hello‘, function(req,res){
let data = {}
data["name"] = "lucy";
data["age"] = "23";
res.send(data);
});
