Node.js URL.origin API

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.

示例 1：

javascript

//Importing the url module
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);

输出：

注意：我们不能使用 url.origin API 设置 URL 的来源。如果我们尝试这样做，那么它将被忽略，并且不会影响原点。
