url.search | Node.js API 文档

<string>

获取和设置网址的序列化的查询部分。

【Gets and sets the serialized query portion of the URL.】

const myURL = new URL('https://example.org/abc?123');
console.log(myURL.search);
// Prints ?123

myURL.search = 'abc=xyz';
console.log(myURL.href);
// Prints https://example.org/abc?abc=xyz

在分配给 search 属性的值中出现的任何无效 URL 字符都将被百分比编码编码。哪些字符需要进行百分比编码的选择，可能会与 url.parse() 和 url.format() 方法生成的结果略有不同。

【Any invalid URL characters appearing in the value assigned the search property will be percent-encoded. The selection of which characters to percent-encode may vary somewhat from what the url.parse() and url.format() methods would produce.】
