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
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(); 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))); $time = time(); $textTpl = "<xml> <ToUserName><![CDATA[".$fromUsername."]]></ToUserName> <FromUserName><![CDATA[".$toUsername."]]></FromUserName> <CreateTime>".$time."</CreateTime> <MsgType><![CDATA[text]]></MsgType> <Content><![CDATA[%s]]></Content> <FuncFlag>0</FuncFlag> </xml>"; $picTpl = "<xml> <ToUserName><![CDATA[".$fromUsername."]]></ToUserName> <FromUserName><![CDATA[".$toUsername."]]></FromUserName> <CreateTime>".$time."</CreateTime> <MsgType><![CDATA[news]]></MsgType> <Content><![CDATA[]]></Content> <ArticleCount>%d</ArticleCount> <Articles> %s </Articles> <FuncFlag>1</FuncFlag> </xml>"; if($this->keyword == 'hi' || $this->keyword == '您好' || $this->keyword == '你好' ||$this->keyword == 'hello2bizuser' ){ $contentStr = "输入关键字开始搜索！";//自定义欢迎回复; echo sprintf($textTpl, $contentStr); }else if( !empty( $this->keyword )){ $this->search(); if($this->articleCount == 0){ $contentStr = "抱歉，没有找到与【{$this->keyword}】相关的文章，要不你更换一下关键字，可能就有结果了哦 :-) "; echo sprintf($textTpl, $contentStr); }else{ echo sprintf($picTpl,$this->articleCount,$this->items); } } }else { echo ""; exit; } } private function search(){ global $dsql; $weixin_posts = $dsql->SetQuery("Select * From `dede_archives` where title like '%".$this->keyword."%' order by id desc LIMIT 0, 5"); $items = ''; $dsql->Execute(); while($weixin_post=$dsql->GetObject()){ $title =$weixin_post->title; $excerpt = $weixin_post->description ;//获取摘要 $thumb = $weixin_post->litpic ;//获取; $link = '/plus/view.php?aid='.$weixin_post->id; $items = $items . $this->get_item($title, $excerpt, $thumb, $link); $this->articleCount++; } if($this->articleCount > 5) $this->articleCount = 5; $this->items = $items; } private function get_item($title, $description, $picUrl, $url){ if(!$description) $description = $title; return ' <item> <Title><![CDATA['.$title.']]></Title> <Discription><![CDATA['.$description.']]></Discription> <PicUrl><![CDATA['.$_SERVER['HTTP_HOST'].$picUrl.']]></PicUrl> <Url><![CDATA['.$_SERVER['HTTP_HOST'].$url.']]></Url> </item> '; } private function checkSignature() { $signature = $_GET["signature"]; $timestamp = $_GET["timestamp"]; $nonce = $_GET["nonce"]; $token = TOKEN; $tmpArr = array($token, $timestamp, $nonce); sort($tmpArr); $tmpStr = implode( $tmpArr ); $tmpStr = sha1( $tmpStr ); if( $tmpStr == $signature ){ return true; }else{ return false; } } }
