nodejs中的url模块

url有一个parse方法，这个方法返回一个json对象。
json对象里有两个常用的属性。
一个是query，表示请求的数据。
另一个是pathname，表示请求的地址。

const urlLib = require("url");
var obj = urlLib.parse("http://www.workplus.com/users?user=lily&pass=123");
/*Url {
  protocol: 'http:',
  slashes: true,
  auth: null,
  host: 'www.workplus.com',
  port: null,
  hostname: 'www.workplus.com',  hash: null,
  search: '?user=lily&pass=123',
  query: 'user=lily&pass=123',
  pathname: '/users',
  path: '/users?user=lily&pass=123',
  href: 'http://www.workplus.com/users?user=lily&pass=123' }*/
console.log(obj);
console.log(obj.query);//user=lily&pass=123
console.log(obj.pathname);///users

var obj = urlLib.parse("http://www.workplus.com/users?user=lily&pass=123",true);
/*Url {
  protocol: 'http:',
  slashes: true,
  auth: null,
  host: 'www.workplus.com',
  port: null,
  hostname: 'www.workplus.com',
  hash: null,
  search: '?user=lily&pass=123',
  query: { user: 'lily', pass: '123' },
  pathname: '/users',
  path: '/users?user=lily&pass=123',
  href: 'http://www.workplus.com/users?user=lily&pass=123' }*/
console.log(obj);
console.log(obj.query);//{ user: 'lily', pass: '123' }
console.log(obj.pathname);///users
