--------------------------------------------
const url=require('url');
var api="http://www.baidu.com?name=nice&age=18";
console.log(url.parse(api));
// query: 'name=nice&age=18'
--------------------------------------------
//
const url=require('url');
var api="http://www.baidu.com?name=nice&age=18";
console.log(url.parse(api,true));
// query: [Object: null prototype] { name: 'nice', age: '18' },
//转换成了对象！
-------------------------------------------
//
学习这个：！
var getValue=url.parse(api,true).query;
console.log(getValue);
怎么写：
const url=require('url');
var api="http://www.baidu.com?name=nice&age=18";
var getValue=url.parse(api,true).query;
console.log(getValue);
-------------------------------------------
//模板字符串
const url=require('url');
var api="http://www.baidu.com?name=nice&age=18";
var getValue=url.parse(api,true).query;
console.log(getValue);
console.log(`姓名：${getValue.name}---年龄：${getValue.age}`);
