[TOC] ### egg 單文件上傳 * 獲取路徑：path.dirname(filepath) ``` const path=require("path"); var filepath='/node/base/path/test.js'; console.log( path.dirname(filepath) ) //輸出/node/base/path ``` * 獲取文件名：path.basename(filename) ``` const path = require("path"); console.log(path.basename("/node/base/path/test.js",".js")); //輸出 test ``` * 獲取擴展名：path.extname(filepath) ``` const path = require("path"); console.log(path.extname("/node/base/path/test.js",".js")); //輸出 .js ``` ***** ### 文件路徑分解/組合 * path.join([…paths]) ``` const path=require("path"); path.join("/temp",'node','/js/test.js') //輸出 \temp\node\js\test.js path.join("/temp",'node','/js/test.js/','..') //輸出 \temp\node\js ``` *****
