分配给 username 属性的值中出现的任何无效 URL 字符将被 百分比编码。选择要进行百分比编码的字符可能与 url.parse() 和 url.format() 方法产生的结果略有不同。

【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.】
