1、path.resolve(ag1,ag2,...)
path.resolve返回当前环境所在路径拼接参数字符串所得到的绝对路径,其中参数可以有多个
const path = require('path');
path.resolve('/foo/bar', './baz') // returns '/foo/bar/baz' path.resolve('/foo/bar', '/tmp/file/') // returns '/tmp/file' path.resolve('wwwroot', 'static_files/png/', '../gif/image.gif') // if the current working directory is /home/myself/node, // this returns '/home/myself/node/wwwroot/static_files/gif/image.gif'
2、path.join(ag1,ag2,...)
const path=require('path'); path.join('a','b'); //返回 a\b path.join(__dirname,'c','main.js') //返回 D:\c\main.js ,__dirname表示当前运行环境绝对路径 //path.join()方法拼接路径,并返回该路径,结合__dirname可以达到path.resolve()方法同样的效果
