织梦如何写API接口实现全站数据生成JSON供其他站点调用

{dede:json url='http://yoursite/json.php' cache=300}
[field:id/]-[field:title/]<br/>
{/dede:json}

require_once(DEDEINC.'/json.class.php');

echo $json->encode($reval);

Array (
[0] => Array ( [id] => 95 [title] => 原图设计)
[1] => Array ( [id] => 113 [title] => ssssssssssss)
[2] => Array ( [id] => 111 [title] => hjhj )
[3] => Array ( [id] => 110 [title] => ssssssssssss)
   )

[
