Node.js URL.host API
url.host 是 url 模块内置的 url 类应用编程接口，用于获取和设置 URL 的主机部分。
语法:
const url.host
返回值:获取并设置 URL 的主机部分。 下面的程序说明了 url.host 方法的使用: 示例 1:
java 描述语言
// node program to demonstrate the
// url.host API as Setter
//importing the module 'url'
const http = require('url');
// creating and initializing myURL
const myURL = new URL('https://example.com:80/foo#ram');
// Display href value of myURL before change
console.log("Before Change");
console.log(myURL.href);
// assigning host portion
// using host
console.log();
myURL.host = 'example.com:82';
// Display href value of myURL after change
console.log("After Change");
console.log(myURL.href);
输出:
Before Change
https://example.com:80/foo#ram
After Change
https://example.com:82/foo#ram
例 2:
java 描述语言
// node program to demonstrate the
// url.host API as Getter
//importing the module 'url'
const http = require('url');
// creating and initializing myURL
const myURL = new URL('https://example.org:82/foo#ram');
// getting the host portion
// using host
const host = myURL.host;
// Display hash value
console.log(host);
输出:
example.org:82
