代码说明
1.实现了调用了图灵的聊天机器人接口,实现了部分功能回复文本消息图文消息,不能接收图片消息
2.关注事件回复欢迎关注
3.获取关注人员的信息
4.memcache缓存
5.网页授权的两种方式
6.创建自定义菜单
6.curl发送请求
7.jssdk预览本机图片
主要有四个文件
1.接收微信服务器消息的页面wx_sample.php
valid(); //接收处理微信服务器转发的xml数据包 $post = $HTTP_RAW_POST_DATA; $weixin->chat($post);
2.配置文件config.php
3.微信网页授权的页面weixin.php
jssdk_signture();var_dump($signPackage);?>
4.类文件 wxApi.class.php
