基于微信公众平台开发SDK(demo)扩展例子
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:
<?php
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)) {
