wp_get_shortlink: 这个函数检索当前页面的短链接(也被称为”漂亮链接”)。短链接是更短、更容易记住的URL,可以用来代替一个页面的完整URL: 这个函数检查Jetpack插件是否安装并激活,如果是,它使用Jetpack API来生成短链接。如果Jetpack没有安装,它就会回到使用默认的WordPress短链接。

返回一个文章、页面、附件或网站的短链接。

这个函数的存在是为了提供一个所有主题和插件都可以针对的短链接标签。一个插件必须挂钩以提供实际的短链接。默认的短链接支持只限于为文章提供?p=风格的链接。插件可以通过{@see ‘pre_get_shortlink’}过滤器短路这个函数,或者通过{@see ‘get_shortlink’}过滤器过滤输出。
