The full URL for a protected links follows this form: 這個指令明確一個安全關鍵字來審核請求。完整的被保護的URL如下表： /**prefix**/*hash*/**reference** *hash* is computed as as 使用md5('參考','安全密碼')函數計算 ~~~ md5 (reference, secret_word); ~~~ **prefix** is the scope of the location block, and must not be '/'. secure_link can only be used in non-root paths. 前綴是定位塊的范圍，絕對不能使用'/'。安全連接只能被用在非根目錄路徑。 ### 變量 ### $secure_link Automatically set to the reference component of the URL, isolated from the prefix and hash.
