忽略/libraries/joomla/document/json下的jDocument类

在我正在开发的一个网站上，我从安装中添加了/public_html/libraries/joomla/document/json，因为它不在那里。该网站运行于1.5版本，我在本地使用的是Joomla 2.5

我的url添加了

&format=json

，但可以看到响应头是text/html。可能2.5版本的文件与1.5版本不兼容。它有以下内容：

<?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;
    }
}

查看1.5版本的raw.php时，我注意到只有很小的差异：

渲染没有公共修改器

在1.5中可能更重要的是，首先调用parent:：render，因此代码现在看起来像：

        $this->_mime = 'application/json';

    }

    {

你是说你刚刚从2.5中提取了一些文件，并将其粘贴到1.5中？不，这是行不通的。@Elin谢谢你消除了不起作用的东西。在一个无关的主题上；你知道API对1.5的引用吗？它似乎不在Joomla网站上，或者他们隐藏得很好。@Elin找到了它：重定向到另一个也被删除的页面。我为那些花时间编写和翻译这些文件的人感到抱歉。
