定义回复消息处理函数

1、文本消息

    private function transmitText($object, $content, $flag = 0){$textTpl = "<xml>
<ToUserName><![CDATA[%s]]></ToUserName>
<FromUserName><![CDATA[%s]]></FromUserName>
<CreateTime>%s</CreateTime>
<MsgType><![CDATA[text]]></MsgType>
<Content><![CDATA[%s]]></Content>
<FuncFlag>%d</FuncFlag>
</xml>";$resultStr = sprintf($textTpl, $object->FromUserName, $object->ToUserName, time(), $content, $flag);return $resultStr;}

 

2、图文消息

    private function transmitNews($object, $arr_item, $flag = 0){if(!is_array($arr_item))return;$itemTpl = "    <item><Title><![CDATA[%s]]></Title><Description><![CDATA[%s]]></Description><PicUrl><![CDATA[%s]]></PicUrl><Url><![CDATA[%s]]></Url></item>
";$item_str = "";foreach ($arr_item as $item)$item_str .= sprintf($itemTpl, $item['Title'], $item['Description'], $item['Picurl'], $item['Url']);$newsTpl = "<xml>
<ToUserName><![CDATA[%s]]></ToUserName>
<FromUserName><![CDATA[%s]]></FromUserName>
<CreateTime>%s</CreateTime>
<MsgType><![CDATA[news]]></MsgType>
<Content><![CDATA[]]></Content>
<ArticleCount>%s</ArticleCount>
<Articles>
$item_str</Articles>
<FuncFlag>%s</FuncFlag>
</xml>";$resultStr = sprintf($newsTpl, $object->FromUserName, $object->ToUserName, time(), count($arr_item), $flag);return $resultStr;}

3、音乐消息

   private function transmitMusic($object, $musicArray, $flag = 0){$itemTpl = "<Music><Title><![CDATA[%s]]></Title><Description><![CDATA[%s]]></Description><MusicUrl><![CDATA[%s]]></MusicUrl><HQMusicUrl><![CDATA[%s]]></HQMusicUrl>
</Music>";$item_str = sprintf($itemTpl, $musicArray['Title'], $musicArray['Description'], $musicArray['MusicUrl'], $musicArray['HQMusicUrl']);$textTpl = "<xml>
<ToUserName><![CDATA[%s]]></ToUserName>
<FromUserName><![CDATA[%s]]></FromUserName>
<CreateTime>%s</CreateTime>
<MsgType><![CDATA[music]]></MsgType>
$item_str
<FuncFlag>%d</FuncFlag>
</xml>";$resultStr = sprintf($textTpl, $object->FromUserName, $object->ToUserName, time(), $flag);return $resultStr;}

构造不同回复消息类型

1、回复文本

        if($keyword == "文本"){$contentStr = "这是个文本消息";$resultStr = $this->transmitText($object, $contentStr, $funcFlag);}

2、回复单图文

        else if($keyword == "图文" || $keyword == "单图文"){$dateArray = array();$dateArray[] = array("Title"=>"单图文标题", "Description"=>"单图文内容", "Picurl"=>"http://discuz.comli.com/weixin/weather/icon/cartoon.jpg", "Url" =>"http://m.cnblogs.com/?u=txw1958");$resultStr = $this->transmitNews($object, $dateArray, $funcFlag);}

3、回复多图文

        else if($keyword == "多图文"){$dateArray = array();$dateArray[] = array("Title"=>"多图文1标题", "Description"=>"", "Picurl"=>"http://discuz.comli.com/weixin/weather/icon/cartoon.jpg", "Url" =>"http://m.cnblogs.com/?u=txw1958");$dateArray[] = array("Title"=>"多图文2标题", "Description"=>"", "Picurl"=>"http://d.hiphotos.bdimg.com/wisegame/pic/item/f3529822720e0cf3ac9f1ada0846f21fbe09aaa3.jpg", "Url" =>"http://m.cnblogs.com/?u=txw1958");$dateArray[] = array("Title"=>"多图文3标题", "Description"=>"", "Picurl"=>"http://g.hiphotos.bdimg.com/wisegame/pic/item/18cb0a46f21fbe090d338acc6a600c338644adfd.jpg", "Url" =>"http://m.cnblogs.com/?u=txw1958");$resultStr = $this->transmitNews($object, $dateArray, $funcFlag);}

4、回复音乐

        else if($keyword == "音乐"){$musicArray = array("Title"=>"最炫民族风", "Description"=>"歌手：凤凰传奇", "MusicUrl"=>"http://121.199.4.61/music/zxmzf.mp3","HQMusicUrl"=>"http://121.199.4.61/music/zxmzf.mp3");$resultStr = $this->transmitMusic($object, $musicArray, $funcFlag);}
