问题描述：在做微信公众号开发的时候，第一次看见微信开发文档 简直就是一脸懵逼啊！都什么跟什么啊，请看下面详解：
1.微信开发需要启用开启开发者模式（不懂的自行百度）
2.填写服务器地址，token
3.服务器配置：
1 <?php 2 3 class Test{ 4 private $token = ‘4512c35162db71cb7ecee5bc5cd65978‘; 5 private $weixin_token = null; 6 /** 7 * @desc 验证微信接入 8 * @author wzh 9 * @qq646943067 10 */ 11 private function valid(){ 12 $echoStr = $_GET["echostr"];
