1.公众号设置

1.1公众号需要经过认证，具有分享接口功能

image.png

1.2填写正确的域名(域名需要经过备案)

image.png

1.3 保存好AppID、AppSecret、设置好ip白名单(非常重要)

2.php代码(需要有php环境下，放到域名目录下)

2.1展示下目录结构-wxDemo

2.6 access_token.php

获取access_token expires_in值为7200表示成功

将获取到的access_token写到access_token.php里

3. 服务器

我的服务器是远程服务器(window serve 2012 r2)

服务器一定要保证可以完全写入文件(这就是我在那坑待了很久的原因)
