如何使用JavaScript獲取一個文件夾路徑URL

Question

我正在嘗試從url獲取一個后文件夾路徑，但不起作用。我不知道如何獲取路徑？

我預期網址名稱，如HTTP：//本地主機/測試/從HTTP：//本地主機/測試/花/

例：

const path = require('path');

var url = http://localhost/testing/flower/

var reqPath = path.join(url, './');

console.log( reqPath );

Answer 1

我建議對字符串進行簡單的手動解析

 function goUp(url){ if (url.endsWith("/")) url = url.substring(0,url.length-1) const lastSlashPosition = url.lastIndexOf("/"); return lastSlashPosition <=7 ? url: url.substring(0,lastSlashPosition); } console.log(goUp("http://localhost/")); console.log(goUp("http://localhost/testing/flower")); console.log(goUp("http://localhost/testing/flower/")); 

Answer 2

要進入目錄，請使用../

const path = require('path');

var url = http://localhost/testing/flower/

var reqPath = path.join(url, '../');

console.log( reqPath );
