dedecms获得某篇文章内容的几种方法，在这里给大家总结了以下三种方法：

1. 使用SQL
{dede:sql sql='Select body from `dede_addonarticle` where aid=146'}  
    [field:body/]  
{/dede:sql}  

2.使用arclist， 用idlist获取，aid 是没用的，在首页记得要获取typeid， 用addfields='body'来直接使用[field:body/]
{dede:arclist typeid='49' idlist='146' addfields='body' channelid='1' }  
                <section class="recommend">  
                    <header class="header">  
                        <h2><a href="[field:arcurl/]">[field:title/]</a></h2>  
                        <a href="[field:arcurl/]" class="more" title="更多...">more</a>  
                    </header>  
                    <div class="content">  
                        [field:body/]  
                    </div>  
                </section>  
{/dede:arclist}  

3.混搭
{dede:arclist typeid='48' limit='0,10'}  
                            <li><time class="date">[field:id runphp='yes']  
$aid = @me;  
$row = $GLOBALS['dsql']->GetOne("Select activitydate From `dede_addonarticle20` where aid='$aid' ");  
@me = "{$row['activitydate']}";  
[/field:id]</time><a href="[field:arcurl/]" title="查看详情">[field:title/]</a></li>  
                        {/dede:arclist}
