首先在前台实例化编辑器时设置后台请求处理的地址：
var ue = UE.getEditor('container',{
serverUrl:'__APP__/Home/Ueditor/UploadSomething',
});然后就是写处理方法：
<?php
namespace Home\Controller;
use Think\Controller;
class UeditorController extends Controller{
/**
* ueditor上传后台处理方法
* @param
*/
public function UploadSomething(){
header("Content-Type: text/html; charset=utf-8");
error_reporting(E_ERROR);
$CONFIG = json_decode(preg_replace("/\/\*[\s\S]+?\*\//", "", file_get_contents("./Public/ueditor/php/config.json")), true);
$action = $_GET['action'];
switch ($action){
case 'config':
$result = json_encode($CONFIG);
break;
case 'uploadimage':
case 'uploadscrawl':
case 'uploadvideo':
case 'uploadfile':
$result = $this->ueditorUpload($CONFIG);
// 图像缩放裁剪处理
if($_GET['action'] == 'uploadimage' or $_GET['action'] == 'uploadscrawl'){
$result = json_decode($result,JSON_UNESCAPED_UNICODE);
// 将引用地址改为相对地址
$imgUrl = $result['url'];
$str = 'Public/img';
$imgUrl = './'.strstr($imgUrl,$str);
// 裁剪并缩放图片
zoom_image($imgUrl,200,200);
$result = json_encode($result,JSON_UNESCAPED_UNICODE);
}
break;
// 列出图片
case 'listimage':
$result = $this->ueditorList($CONFIG);
break;
// 列出文件
case 'listfile':

break;

case 'catchimage':

}上面的处理中用到了上传文件类，直接拿百度原来的那个上传类就可以了，Uploader.class.php将文件复制到Think/Library/Vendor目录下，使用时用Vendor()函数调用即可。
