如何使用JavaScript获取一个文件夹路径URL

Question

我正在尝试从url获取一个后文件夹路径，但不起作用。我不知道如何获取路径？

我预期网址名称，如HTTP：//本地主机/测试/从HTTP：//本地主机/测试/花/

例：

const path = require('path');

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

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

console.log( reqPath );

Answer 1

我建议对字符串进行简单的手动解析

 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

要进入目录，请使用../

const path = require('path');

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

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

console.log( reqPath );
