在url中获取正确的路径

Question

Node.js是否有一个URL模块来解决这个问题？

getCorrectUrl('http://www.domain.com/folder/folder/', '../../img/some.jpg'); // http://www.domain.com/img/some.jpg
getCorrectUrl('http://www.domain.com/folder/folder/', './img/some.jpg'); // http://www.domain.com/img/some.jpg
getCorrectUrl('http://www.domain.com/folder/folder/', 'http://www.domain.com/img/some.jpg'); // http://www.domain.com/img/some.jpg
getCorrectUrl('http://www.domain.com/folder/folder/', '../img/some.jpg'); // http://www.domain.com/folder/img/some.jpg
getCorrectUrl('http://www.domain.com/folder/folder/', 'img/some.jpg'); // http://www.domain.com/folder/folder/img/some.jpg

Answer 1

使用原生URL模块。你要找的是url.resolve()。

url.resolve('http://www.domain.com/folder/folder/', '../img/some.jpg');
// http://www.domain.com/folder/img/some.jpg
