拿到 GET 请求传递过来的参数
使用URL模块, 语法示例如下

url.format(urlObject)
url.parse(urlString[, parseQueryString[, slashesDenoteHost]])
url.format(urlObject): 将路径转换为对象

url.parse(urlString[, parseQueryString[, slashesDenoteHost]]): 将对象转换为路径

let url = require("url");
let http = require("http");

let str = "http://root:123456@www.it6666.top:80/index.html?name=BNTang&age=68#banner";
let obj = url.parse(str, true);
console.log(obj);
console.log(obj.query.name);
console.log(obj.query.age);
let url = require("url");
let http = require("http");

// 1.创建一个服务器实例对象
let server = http.createServer();
server.on("request", function (req, res) {
    console.log(req.url);
    let obj = url.parse(req.url, true);
    res.end(obj.query.name + "----" + obj.query.age);
});

// 2.指定监听的端口
server.listen(3000);
