本文实例讲述了php实现基于微信公众平台开发sdk(demo)扩展的方法。分享给大家供大家参考。具体分析如下：
该扩展基于官方的微信公众平台sdk,这里只做了简单地封装,实现了一些基本的功能(如天气查询,翻译,自动聊天机器人,自定义菜单接口)仅供学习之用.代码如下:
复制代码 代码如下:
define(token, xingans);
$wechatobj = new wechatcallbackapitest();
$wechatobj->responsemsg();
class wechatcallbackapitest
{
//签名验证公共接口
public function valid()
{
$echostr = $_get[echostr];
if($this->checksignature()){
echo $echostr;
exit;
}
}
//主入口处理函数
public function responsemsg()
{
$poststr = $globals[http_raw_post_data];
if (!emptyempty($poststr)){
$postobj = simplexml_load_string($poststr, 'simplexmlelement', libxml_nocdata);
$msgtype=trim($postobj->msgtype);
switch($msgtype){
case 'text':
$resultstr=$this->handletext($postobj);
break;
case 'event':
$resultstr=$this->handleevent($postobj);
break;
default:
$resultstr=$this->handledefault($postobj);
break;
}
echo $resultstr;
}else {
echo error;
exit;
}
}
//处理文本消息
private function handletext($obj){
$keyword=trim($obj->content);
if(preg_match('/天气/',$keyword)){
$contentstr=$this->handleweather($obj);
}elseif(preg_match('/翻译/',$keyword)){
$contentstr=$this->handletranslation($obj);
}else{
$contentstr=$this->handlechat($obj);
}
return $this->handlestr($obj,$contentstr);
}
//处理天气
