【php】Wordpress同步内容到微信公众号

利用官方接口实现内容的同步的几个步骤：
1.获取token接口，appid和secret可以从微信公众号后台查看。

1. https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=你的appid&secret=你的secret";

复制代码

2.上传封面图片，获取返回的id

1. https://api.weixin.qq.com/cgi-bin/material/add_material?access_token=$token

复制代码

3.构造上传的内容
4.发送构造的内容
https://api.weixin.qq.com/cgi-bin/material/add_news?access_token=$token

完整代码，在functions.php中添加即可。

1. //获取微信公众号的token
   
2. function GetWeixinToken(){
