一、说明
1、根据慕课网上的教程为基础，这是前两个基础教程：
PHP实现微信公众平台开发—基础篇：https://www.imooc.com/video/9316
PHP实现微信公众平台开发—提升篇 ：https://www.imooc.com/video/10231
2、慕课上视频讲解用的是thinkphp早期版本，我用的是thinkphp3.2.3版本。可以看慕课视频进行学习，讲的比较详细
PHP微信公众平台开发高级篇—自定义菜单：https://www.imooc.com/video/11332
3、代码亲测有效
二、IndexController控制器代码
<?php

use Think\Controller;
class IndexController extends Controller{
public function __construct(){
}//可以不写
public function index(){
//获得参数 signature nonce token timestamp echostr
$nonce = $_GET['nonce'];
$token = 'weixin';
$timestamp = $_GET['timestamp'];
$echostr = $_GET['echostr'];
$signature = $_GET['signature'];
//形成数组，然后按字典序排序
$array = array();
$array = array($nonce, $timestamp, $token);
sort($array);
//拼接成字符串,sha1加密 ，然后与signature进行校验
$str = sha1( implode( $array ) );
if( $str == $signature && $echostr ){
//第一次接入weixin api接口的时候
echo $echostr;
exit;
}else{
$this->definedItem();
$this->reponseMsg();
}
}
// 接收事件推送并回复
public function reponseMsg(){
//1.获取到微信推送过来post数据（xml格式）
