在 Wordpress 自定义内容类型、分类、标签 这篇文章中，我们知道了如何自定义文章类型，在 Wordpress 的伪静态设置 这篇文章中讲了如何开启 wordpress 的伪静态，但是当你细心一点，会发现自定义的内容类型，伪静态貌似没有生效，访问文章的话，链接会类似 http://localhost:8080/sites/通义千问 这样，还会出现中文，和我们预想的 http://localhost:8080/sites/1.html 有较大的差异，那么应该如何对自定义内容类型做伪静态呢？
直接上代码，详细可以看这篇介绍WordPress 修改自定义文章类型的固定链接结构 – WordPress大学，将下面的代码放到你的插件入口，或者主题的 functions.php 中，能调用到就可以。
