这次作业难产了,原因在于我太自大了,在赶进度的过程中不重视作业和代码,导致卡在了微信公众号这里。我开始反省我是为了赶进度还是为了学知识,于是我根据在微信那里不懂不足的地方记下来,在重新看视频和翻看tp5的手册,终于终于搞了个7788,也算是写出来了。

controller/Weixin.php

实例

<?php 
namespace app\index\controller;
use think\Controller;

class Weixin extends Controller
{
	public function __construct()
	{
		parent::__construct();
					//model/weixin
		$this->model = model('Weixin');
	}
	//验证
	public function index()
	{					
		$vail = $this->model->vail();
		if (!$vail) {
			exit('signature error');
		}
			exit(input('get.echostr'));
	}

}

 ?>
