node.js中url是什么

protocol :// hostname[:port] / path / [;parameters][?query]#fragment

//使用url库将字符串转化为对象
const url = require('url')
let urlString = 'https://127.0.0.1/wl/test/123/haha?name=123&age=18'
let urlObj = url.parse(urlString)
console.log(urlObj)

//将对象转为字符串
 
let obj = {
    protocol: 'https:',
    slashes: true,
    auth: null,
    host: '127.0.0.1',
    port: null,
    hostname: '127.0.0.1',
    hash: null,
    search: '?name=123&age=18',
    query: 'name=123&age=18',
    pathname: '/wl/test/123/haha',
    path: '/wl/test/123/haha?name=123&age=18',
    href: 'https://127.0.0.1/wl/test/123/haha?name=123&age=18'
}
 
let string = url.format(obj)
console.log(string)
