dedecms增加微信公众号平台发布插件

现在微信公众号很火,基本是个网站都会再运营一个公众号,因此我们用DEDECMS建站也需要与时俱进对接进入公众号功能,在公众号发布文章,提高用户粘度

  1. 把以下代码保存为winxin.php放到dede程序的plus目录下.




代码如下   

<?php
 
define("TOKEN", "weixin");
require_once(dirname(__FILE__)."/..//common.inc.php");  
$dsql = new DedeSql(false);
$wechatObj = new wechatCallback();
$wechatObj->valid();

    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;
