url.username


获取及设置 URL 的用户名部分。

const myURL = new URL('https://abc:xyz@example.com');
console.log(myURL.username);
// 打印 abc

myURL.username = '123';
console.log(myURL.href);
// 打印 https://123:xyz@example.com/

分配给 username 属性的值中包含的无效 URL 字符是百分比编码的。 选择哪些字符进行百分比编码可能与 url.parse()url.format() 方法产生的内容有所不同。

Gets and sets the username portion of the URL.

const myURL = new URL('https://abc:xyz@example.com');
console.log(myURL.username);
// Prints abc

myURL.username = '123';
console.log(myURL.href);
// Prints https://123:xyz@example.com/

Any invalid URL characters appearing in the value assigned the username 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.
