这篇文章主要介绍了php实现基于微信公众平台开发SDK(demo)扩展的方法,包括处理文本消息、天气、翻译、聊天信息及自定义菜单等,需要的朋友可以参考下
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,$contentStr);
}
//处理天气
private function handleWeather($obj){
$keyword=mb_substr($obj->Content,-2,2,'utf-8');
$zone=mb_substr($obj->Content,0,-2,'utf-8');
if($keyword=='天气' && !emptyempty($zone)){
$zoneArr=json_decode(file_get_contents('http://api.k780.com:88/?app=weather.city&format=json'),true);
$zoneArr=$zoneArr['result'];
$cityId='';
foreach($zoneArr as $value){
if($zone==$value['citynm']){
$cityId=$value['weaid'];
休息;
}
}
if(!emptyempty($cityId)){
$data=file_get_contents("http://api.k780.com:88/?app=weather.today&weaid=$cityId&appkey=10638&sign=3736578f099375665f9f141a6326b757&format=json");
