jDocument類在/ libraries/joomla/document/json被忽略

在我正在處理的網站上，我從我的安裝中添加了/ public_html/libraries/joomla/document/json，因爲它不在那裏。該網站運行在1.5和本地我使用Joomla 2.5jDocument類在/ libraries/joomla/document/json被忽略

我的網址有添加&format=json，但可以看到響應標頭是text/html。也許2.5中的文件與1.5不兼容。它具有以下內容：

<?php 
defined('JPATH_PLATFORM') or die; 
class JDocumentJSON extends JDocument 
{ 
    protected $_name = 'joomla'; 
    public function __construct($options = array()) 
    { 
     parent::__construct($options); 
     $this->_mime = 'application/json'; 
     $this->_type = 'json'; 
    } 
    public function render($cache = false, $params = array()) 
    { 
     JResponse::allowCache(false); 
     JResponse::setHeader('Content-disposition', 'attachment; filename="' . $this->getName() . '.json"', true); 

     parent::render(); 

     return $this->getBuffer(); 
    } 
    public function getName() 
    { 
     return $this->_name; 
    } 
    public function setName($name = 'joomla') 
    { 
     $this->_name = $name; 

     return $this; 
    } 
}

你是說你只是從2.5中拉出一些文件並將其卡入1.5？不，這不會起作用。 – Elin

@Elin謝謝你消除不起作用的東西。在一個不相關的主題上;你知道1.5的API參考嗎？它似乎不在Joomla網站上，或者它們隱藏起來很不錯。 – HMR

@Elin發現它：http://docs.joomla.org/Framework/1.5重定向到另一個也被刪除的頁面。我爲所有那些花時間撰寫和翻譯這些文件的人感到抱歉。 – HMR

檢查的1.5版本raw.php我發現只有很少的不同之處：

呈現不具有公共修飾符

也許在1.5更重要父::呈現先調用，所以現在的代碼如下所示：

    { 
     parent::__construct($options); 
     $this->_mime = 'application/json'; 
     $this->_type = 'json'; 
    } 

    /**

    function render($cache = false, $params = array()) 
    { 
     parent::render(); 
     JResponse::allowCache(false); 
     JResponse::setHeader('Content-disposition', 'attachment; filename="' . $this->getName() . '.json"', true); 
     return $this->getBuffer(); 
    }

    public function setName($name = 'joomla') 
    { 
     $this->_name = $name; 
     return $this; 
    } 
}

標題是正確設置現在
