postman连接不了localhost问题解决

学习搭建服务器可用postman 连接不了localhost的端口

网上好多教程是这样连接

看完视频后我们是这样

找了大量资料都解决不了，什么版本，什么证书的都不好使，最简单的就是去掉http：//

//get 测试

const http=require(http)
const querystring=require(querystring)

const server=http.createServer((req, res)=>{
   
    //GET
    console.log(method,req.method)
    const url=req.url
    //  /
    console.log(url:,url)
    req.query=querystring.parse(url.split(?)[1])
    console.log(query:,req.query)

    res.end(
        JSON.stringify(req.query)
    )

})

server.listen(8000)
