wp_get_shortlink: 這個函式檢索當前頁面的短連結(也被稱為”漂亮連結”)。短連結是更短、更容易記住的URL,可以用來代替一個頁面的完整URL: 這個函式檢查Jetpack外掛是否安裝並啟用,如果是,它使用Jetpack API來生成短連結。如果Jetpack沒有安裝,它就會回到使用預設的WordPress短連結。

返回一個文章、頁面、附件或網站的短連結。

這個函式的存在是為了提供一個所有主題和外掛都可以針對的短連結標籤。一個外掛必須掛鉤以提供實際的短連結。預設的短連結支援只限於為文章提供?p=風格的連結。外掛可以通過{@see ‘pre_get_shortlink’}過濾器短路這個函式,或者通過{@see ‘get_shortlink’}過濾器過濾輸出。
