本文目录[隐藏]1目标2实现方法3代码
固定链接设为 /archives/%postname%.html 时可以让页面看起来像静态页，同时会使分页链接变得十分奇怪，比如评论的分页链接会变成”hello-world.html/comment-page-1#comments”，html既然是后缀就应该一直在最后，本文介绍如何实现。
目标
假设页面链接为hello-world.html
当在文章中插入分页时，希望分页链接格式为 hello-world/page-2.html
评论分页链接则为 hello-world/comment-page-2.html
实现方法
通过filter将分页链接改成希望的格式，分别用到vwp_link_pages_link 和 get_comments_pagenum_link。添加自定义跳转规则，利用filter rewrite_rules_array取消Canonical URL（标准链接）跳转，否则使用新链接访问时WordPress会强制跳转到原来的链接
代码
下面这段代码放在主题的functions.php中，保存后需要到设置中重新保存一下固定链接。

本代码适用于固定链接格式为/archives/%postname%.html，若固定格式不同需要作相应修改，修改方法见下文。
若固定链接格式为/%postname%.html，请修改规则，将

本文介绍的方法演示了修改固定链接格式、并添加新Rewrite rules的方法，适用于其他情况。例如修改custom post type的固定链接，不同的是用哪个filter来修改链接输出格式。
