grails - Shiro标签 'isLoggedIn'和 'authenticated'表示同一意思吗？

Question

我刚刚开始使用Grails和Shiro，并且正在考虑将Shiro添加到现有项目中。

我想知道Shiro标签isLoggedIn和authenticated的意思是否相同(即始终产生相同的结果)吗？

Grails Shiro Plugin page似乎表明:

The tags <shiro:isLoggedIn> and <shiro:authenticated> check for an authenticated user, the tag <shiro:user> checks for a known user (authenticated or remembered) and the tag <shiro:remembered> checks only for a remembered user.

但这几乎不是深入的描述，也没有解释为什么如果它们相同则两者都存在。

Answer 1

是的，它们是完全一样的。 Here is the source code:

/**
 * This tag only writes its body to the output if the current user
 * is logged in.
 */
 def isLoggedIn = { attrs, body ->
    if (checkAuthenticated()) {
        out << body()
    }
}

/**
 * A synonym for 'isLoggedIn'. This is the same name as used by
 * the standard Shiro tag library.
 */
def authenticated = isLoggedIn
