url.origin是 url 模块中URL 类的内置应用程序编程接口 (API)。
url.origin API 用于获取 URL 源的只读序列化。

Syntax: url.origin
url : It is an object created by URL constructor.

const url = require('url');
 
//Creating an URL_1 object with URL constructor.
const URL_1 = new URL("https://www.geeksforgeeks.org/geeks");
 
//Getting origin of above created URL_1 object
console.log(URL_1.origin);
