把以下代码保存为winxin.PHP放到dede程序的plus目录下.

PHP
 
define("TOKEN","weixin");
require_once(dirname(__FILE__)."/..//common.inc.PHP");  
$dsql = new Dedesql(false);
$wechatObj = new wechatCallback();
$wechatObj->valid();
 
class wechatCallback
{
    private $items = '';
    private $articleCount = 0;
    private $key = '';
 
 public function valid()
    {
        $echoStr = $_GET["echostr"];
 
        //valid signature,option
        if($this->checkSignature()){
         echo $echoStr;
            $this->responseMsg();
 
         exit;
        }
    }
 
    public function responseMsg()
    {
  //get post data,May be due to the different environments
  $postStr = $GLOBALS["HTTP_RAW_POST_DATA"];
 
       //extract post data
  if (!empty($postStr)){
 
               $postObj = simplexml_load_string($postStr,'SimpleXMLElement',LIBXML_NOCDATA);
                $fromUsername = $postObj->FromUserName;
                $toUsername = $postObj->ToUserName;
                $this->keyword = strtolower(trim(("UTF-8","gb2312",$postObj->Content)));
