path 模塊

提供了操作路徑的功能

	說明
path. resolve	拼接規范的絕對路徑
path. sep	獲取操作系統的路徑分隔符
path. parse	解析路徑并返回對象
path. basename	獲取路徑的基礎名稱
path. dirname	獲取路徑的目錄名
path. extname	獲得路徑的擴展名

resolve

拼接規范的絕對路徑

const path = require('path')console.log(__dirname)
let pathUrl =path.resolve(__dirname,'./file')
console.log(pathUrl)

sep

獲取操作系統的路徑分隔符;
windows 中是 \
linux 中是 /

const path = require('path')console.log(path.sep);

parse

解析路徑并返回對象

const path = require('path')
let pathUrl =path.resolve(__dirname,'./file')
console.log(path.parse(pathUrl))

返回的結果是一個json對象

{root: '/',dir: '/Users/layman/Desktop/node/node_learn',base: 'file',ext: '',name: 'file'
