parse方法

parse方法将url解析为对象，第一个参数是要解析成对象的url字符串，第二个是是否查询参数，为true，查询参数解析为对象，第三个是是否以//解析主机

const path = require("path");
const url=require("url");let str="/images/fff/123/jj.jpg";
console.log(path.parse(str));
结果：
{root: '/',dir: '/images/fff/123',base: 'jj.jpg',ext: '.jpg',name: 'jj'
}console.log(path.sep);// \
let u = "//www.baidu:8080/images/fff/123/jj.jpg?id=1&name=tom#hash";
console.log(url.parse(u));//query结果：
\
Url {protocol: null,slashes: null,auth: null,host: null,port: null,hostname: null,hash: '#hash',search: '?id=1&name=tom',query: 'id=1&name=tom',pathname: '//www.baidu:8080/images/fff/123/jj.jpg',//pathname 属性是一个可读可写的字符串，可设置或返回当前 URL 的路径部分path: '//www.baidu:8080/images/fff/123/jj.jpg?id=1&name=tom',href: '//www.baidu:8080/images/fff/123/jj.jpg?id=1&name=tom#hash'
}
console.log(url.parse(u,true));Url {protocol: null,slashes: null,auth: null,host: null,port: null,hostname: null,hash: '#hash',search: '?id=1&name=tom',query: [Object: null prototype] { id: '1', name: 'tom' },//第二个参数为true，query属性就会从查询字符串格式（“a=1&b=2”）转换为了对象格式（{a: 1,b: 2}）pathname: '//www.baidu:8080/images/fff/123/jj.jpg',path: '//www.baidu:8080/images/fff/123/jj.jpg?id=1&name=tom',href: '//www.baidu:8080/images/fff/123/jj.jpg?id=1&name=tom#hash'
}
console.log(url.parse(u,  true, true));
Url {protocol: null,slashes: true,auth: null,host: 'www.baidu:8080',//hostport: '8080',hostname: 'www.baidu',hash: '#hash',search: '?id=1&name=tom',query: [Object: null prototype] { id: '1', name: 'tom' },pathname: '/images/fff/123/jj.jpg',path: '/images/fff/123/jj.jpg?id=1&name=tom',href: '//www.baidu:8080/images/fff/123/jj.jpg?id=1&name=tom#hash'
