京东的富文本编辑器数据，通过观察发现图片都是background-img里面，这样不太好让图片宽度100%，不变形。于是通过后端php把所有的图片路径都匹配出来，然后显示即可，显示的时候注意宽度100%，高度不限制就不会变形了。

后端php处理数据代码如下,处理逻辑如下如果能匹配出来background-image的数组，则认定是京东的产品详情，然后把图片一个一个输出就可以了，如果不是京东产品原样子显示即可。

     <?php
     preg_match_all("/background-image:url((.+?));/",  $info['goodwx'], $match);
     if(!empty($match[2])){
              foreach ($match[2] as $k=>$v){
                     $v=trim($v,"(");
                      $v=trim($v,")");
                      echo "<img src='http:".$v."'  />";
              } 
     }else {
     
             echo $info['goodwx'];
    
     }
     ?>  

处理后的html输出显示如下图，然后通过css控制下class等于exchange下面的img标签width都是100%，高度不限制，就不变形了！
