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。
https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=你的appid&secret=你的secret";
2.上传封面图片，获取返回的id
https://api.weixin.qq.com/cgi-bin/material/add_material?access_token=$token
3.构造上传的内容
4.发送构造的内容
https://api.weixin.qq.com/cgi-bin/material/add_news?access_token=$token
完整代码，在functions.php中添加即可。
