我已经在Angular 2中建立了SPA，并将其托管在Firebase Hosting上。我专门为爬网机器人构建了一些额外的静态html页面（因为它们不读取更新的动态html，仅读取初始index.html），现在我需要将来自机器人的HTTP请求的URL重写到这些静态页面。

我知道如何在.htaccess文件中执行此操作，但是我不知道如何转换firebase.json文件中的重写条件。

这是我的.htaccess：

RewriteEngine On
 
# Remove trailing /
RewriteRule ^(.*)/$ /$1 [L,R=301]
 
# Rewrite spiders to static html
RewriteCond %{HTTP_USER_AGENT} (googlebot|bingbot|msnbot|yahoo|Baidu|aolbuild|facebookexternalhit|iaskspider|DuckDuckBot|Applebot|Almaden|iarchive|archive.org_bot) [NC]
RewriteCond %{DOCUMENT_ROOT}/static%{REQUEST_URI}.html -f
RewriteRule ^(.*)$ /static/$1.html [L]
 
# Rewrite spiders to static index.html
RewriteCond %{HTTP_USER_AGENT} (googlebot|bingbot|msnbot|yahoo|Baidu|aolbuild|facebookexternalhit|iaskspider|DuckDuckBot|Applebot|Almaden|iarchive|archive.org_bot) [NC]
RewriteCond %{REQUEST_URI} "^/$"
RewriteRule ^ /static/index.html [L]
 
# If an existing asset or directory is requested, serve it
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -f [OR]
RewriteCond %{DOCUMENT_ROOT}%{REQUEST_URI} -d
RewriteRule ^ - [L]
 
# If the requested resource doesn't exist, use the Angular app entry point
RewriteRule ^ /index.html

我已经阅读了Firebase关于“配置重写”的文档，但无法弄清楚如何以特定的用户代理为目标。

有任何想法吗？
