请教一下如何更改路由以实现单域名博客功能

[CodeZhangBorui]

希望使用 UOJ 官方版来搭建学校 OJ，尝试自行修改 /opt/uoj/web/app/controllers/subdomain/blog/route.php：

<?php

Route::pattern('blog_username', '[a-zA-Z0-9_\-]{1,20}');

Route::group([
                'domain' => UOJConfig::$data['web']['main']['host'],
                'protocol' => UOJConfig::$data['web']['main']['protocol'],
                'onload' => function() {
                        UOJContext::setupBlog();
                }
        ], function() {
                Route::any("/blog/{blog_username}/", '/subdomain/blog/index.php');
                Route::any("/blog/{blog_username}/archive", '/subdomain/blog/archive.php');
                Route::any("/blog/{blog_username}/aboutme", '/subdomain/blog/aboutme.php');
                Route::any("/blog/{blog_username}/click-zan", '/click_zan.php');
                Route::any("/blog/{blog_username}/blog/{id}", '/subdomain/blog/blog.php');
                Route::any("/blog/{blog_username}/slide/{id}", '/subdomain/blog/slide.php');
                Route::any("/blog/{blog_username}/blog/(?:{id}|new)/write", '/subdomain/blog/blog_write.php?type=B');
                Route::any("/blog/{blog_username}/slide/(?:{id}|new)/write", '/subdomain/blog/blog_write.php?type=S');
                Route::any("/blog/{blog_username}/blog/{id}/delete", '/subdomain/blog/blog_delete.php');
                Route::any("/blog/{blog_username}/blog/{id}/content.md", '/download.php?type=blog-md');
                Route::any("/blog/{blog_username}/slide/{id}/content.yaml", '/download.php?type=slide-yaml');
        }
);

来实现单域名博客功能，但是修改完后路由 /blog/root 返回 404。

不太会 PHP，请教一下是哪里错了还是需要额外的修改？
