const http = require("http")
const url = require("url")
const { createProxyMiddleware } = require("http-proxy-middleware")

const server = http.createServer((req, res) => {
    const urlStr = req.url;
    if (/\/proxy/.test(urlStr)) {
        const proxy = createProxyMiddleware('/proxy', {
            target: 'http://mobile.pinduoduo.com',
            changeOrigin: true
        })
        console.log("111");
        proxy(req, res)
    }else if(/\api/.test(urlStr)){
        const proxy2 = createProxyMiddleware('/api',{
            target:"https://gate.lagou.com",
            changeOrigin:true,
            pathRewrite:{
                '^/api':''
            }
        })
        console.log("222");
        proxy2(req,res)
    }else{
        console.log("error");
        
    }
})

server.listen(5080, () => {
    console.log('localhost:5080 Listen...');
})

 

可以看到 当我们访问  http://localhost:5080/api时
