k2_content模块输出json数据格式

k2_content模块是k2的一个自带的强大的内容输出模块，它不仅可以按你的要求输出文章列表，还可以输出json格式的数据。

此功能需要使用k2 2.6.x或以上的版本。

输出Json数据的方法：

在对应的k2_content模块的模板文件找到以下代码：

<?php echo JRoute::_('index.php?option=com_k2&view=itemlist&format=feed&moduleID='.$module->id); ?>

这是模块的rss订阅链接地址，将这地址中的format=feed改成format=json就可以，即

<?php echo  JRoute::_('index.php?option=com_k2&view=itemlist&format=feed&moduleID='.$module->id);  ?>

以上即为json格式的数据源地址。

k2_content模块的json数据格式示例：
