我想通过 .htaccess 模拟虚拟主机,所以我想将主机名重写为子文件夹。它可以工作,但在某些 URL 上它不会重写而是重定向。
这是我的.htacess 文件:
RewriteEngine on
RewriteBase /
# Rewrite from subdomains to subfolders with builds
RewriteCond %{HTTP_HOST} ^(.*)\.(.*)\.ci\.example\.com$
RewriteCond %{REQUEST_URI} !^/builds/
RewriteCond %{REQUEST_URI} !^/robots.txt
RewriteRule ^(.*)$ /builds/%2/%1/$1 [PT]
# Example project
RewriteCond %{HTTP_HOST} ^old\.domain\.com$ [NC,OR]
RewriteCond %{HTTP_HOST} ^example\.com$ [NC]
RewriteRule ^(.*)$ http://www.example.com/$1 [R=301,L]
# Rewrite production to master subfolder
RewriteCond %{HTTP_HOST} ^www\.example\.com$
RewriteCond %{REQUEST_URI} !^/builds/
RewriteRule ^(.*)$ builds/example-project/master/$1 [PT]
例如,如果我访问,http://example.com/
它将正确重写为/builds/sum/folder
。如果访问http://example.com/page.html
,它将重写为/builds/sum/folder/page.html
。但如果我访问,http://example.com/folder
它将不会重写,而是 301 重定向到/builds/sum/folder/folder
(并在那里加载index.html
)。
为什么它总是重写,但如果目标路径不是现有文件而是包含 index.html 的文件夹,则会重定向?(我想重写所有内容,因此浏览器中的 URL 不会改变。)
编辑:为了更好地理解发生了什么:
