使用JavaScript将相对路径转换为绝对路径

const relativePath = 'example.html';
const baseUrl = 'https://www.example.com/';
const absolutePath = new URL(relativePath, baseUrl).href;
console.log(absolutePath); // 输出：https://www.example.com/example.html

const relativePath = 'example.html';
const baseUrl = 'https://www.example.com/';
const absolutePath = baseUrl + relativePath;
console.log(absolutePath); // 输出：https://www.example.com/example.html

const path = require('path');
const relativePath = 'example.html';
const basePath = '/var/www/html/';
const absolutePath = path.resolve(basePath, relativePath);
console.log(absolutePath); // 输出：/var/www/html/example.html
