微信开发(二)自己的代码

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

<?php
    require "./config.php";
    require "./wxApi.class.php";

    $echostr = $_GET['echostr'];

    $weixin = new wxApi(APPID, APPSECRET);

    $weixin->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

<?php
define("TOKEN", "xxx");
define("APPID", "xxxxxxxxxxx");
define("APPSECRET", "xxxxxxxxxxxx");

3.微信网页授权的页面weixin.php

<?php
require "./config.php";
require "./wxApi.class.php";

$echostr = $_GET['echostr'];

$weixin = new wxApi(APPID, APPSECRET);

$signPackage = $weixin->jssdk_signture();
var_dump($signPackage);
?>
