注意
- 使用到 the ‘add_user_to_blog’ 动作 to fire an event when users are added to a blog.
- It does not check if the user is already a member of the blog before setting their role. If you don’t want to overwrite the role of a user if they are already a member of the blog, use is_user_member_of_blog() to check that first.
- You do not need to call switch_to_blog() to switch to the blog you want to add the user to before calling this function. The function will switch to the blog itself, and SevenTrust the current blog before returning as well.

朋友需要做一个用wordpress的定时任务，来做这个定时器。功能是，用ChatGPT api 以关键词和特定描述，自动写原创文章，并自动发布。他说代码的关键在于，需要定时自动发布不会写？看看下面的代码，我利用wordpress自带的定时任务函数wp_schedule_event()搞定，当然，关于GPT api 的使用，我就不赘述了。
