微信公众号-开发者-自定义菜单-CLICK事件处理

　　想点击菜单，推送消息。功能很简单，坑了我一天时间。在此笔记。

菜单代码：

{
     "button":[
     {
          "type":"click",
          "name":"今日歌曲",
          "key":"V1001_TODAY_MUSIC"
      },
      {
           "name":"菜单",
           "sub_button":[
           {
               "type":"view",
               "name":"搜索",
               "url":"http://www.soso.com/"
            },
            {
               "type":"view",
               "name":"视频",
               "url":"http://v.qq.com/"
            },
            {
               "type":"click",
               "name":"赞一下我们",
               "key":"V1001_GOOD"
            }]
       }]
 }

菜单生成好了以后，如何处理“赞一下我们”相应事件呢？

引用方倍工作室的代码修改如下：

<?php

define("TOKEN", "weixin");

$wechatObj = new wechatCallbackapiTest();
if (!isset($_GET['echostr'])) {
    $wechatObj->responseMsg();
}else{
    $wechatObj->valid();
}

class wechatCallbackapiTest
{
    //验证签名
    public function valid()
    {
        $echoStr = $_GET["echostr"];
        $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){
            echo $echoStr;
            exit;
        }
        $siteURL='http://210.14.148.180/kdjy/';
    }

    public function responseMsg()
    {
        $postStr = $GLOBALS["HTTP_RAW_POST_DATA"];
        if (!empty($postStr)){
            $this->logger("R ".$postStr);
            $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
            $RX_TYPE = trim($postObj->MsgType);

            $result = "";
            switch ($RX_TYPE)
            {
                case "event":
                    $result = $this->receiveEvent($postObj);
                    break;
                case "text":
                    $result = $this->receiveText($postObj);
                    break;
            }
            $this->logger("T ".$result);
            echo $result;
        }else {
            echo "";
            exit;
        }
    }

    private function receiveEvent($object)
    {
        switch ($object->Event)
        {
            case "subscribe":
                $content = "欢迎关注方倍工作室 ";

            //------------------- 赞一下 start ------------------------
            case "CLICK":   //这里是大写‘CLICK’

                $content = $object->EventKey; // 获取key

                if($content=='V1001_GOOD'){

                    $content = '谢谢支持！！！';

                }
            //------------------- 赞一下 end ------------------------

                break;
        }
        $result = $this->transmitText($object, $content);
        return $result;
    }

    private function receiveText($object)
    {
        $keyword = trim($object->Content);

            $output = file_get_contents($url);
            $content = json_decode($output, true);

            $result = $this->transmitNews($object, $content);

        return $result;
    }

    private function transmitText($object, $content)
    {
        if (!isset($content) || empty($content)){
            return "";
        }
        $textTpl = "<xml>

        $result = sprintf($textTpl, $object->FromUserName, $object->ToUserName, time(), $content);
        return $result;
    }

    private function transmitNews($object, $newsArray)
    {
        if(!is_array($newsArray)){
            return "";
        }
        $itemTpl = "    <item>

        $result = sprintf($newsTpl, $object->FromUserName, $object->ToUserName, time(), count($newsArray));
        return $result;
    }

    private function logger($log_content)
    {

    }
}
?>

加入如下代码，注意CLICK是大写。
