包路径：org.jsoup.safety.Whitelist
类名称：Whitelist
方法名：addProtocols

Whitelist.addProtocols介绍

[英]Add allowed URL protocols for an element's URL attribute. This restricts the possible values of the attribute to URLs with the defined protocol.

E.g.: addProtocols("a", "href", "ftp", "http", "https")

To allow a link to an in-page URL anchor (i.e. <a href="#anchor">, add a #:
E.g.: addProtocols("a", "href", "#")
[中]为元素的URL属性添加允许的URL协议。这将属性的可能值限制为具有已定义协议的URL。
例如：addProtocols("a", "href", "ftp", "http", "https")
要允许链接到页面内URL锚（即<a href="#anchor">，请添加#：
例如：addProtocols("a", "href", "#")
