htaccess 301 重定向到语言子目录

Question

我将网站网址更改为接受不同的语言，因此，我将网站内容移动为默认语言

从：www.site.com 到：www.site.com/en

现在，我从 php 进行重定向，如果 $_GET['lang'] 不存在或 $_GET['path'] 存在，重定向到 site.com/en 或 site.com/en/(path) 但我认为 301 重定向从根到文件夹更好。

我该如何编写这条规则？

这是我的 htaccess 文件：

RewriteEngine on
RewriteBase /

RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]

RewriteRule ^download/(.*)$ php/download.php?id=$1 [L]

# with language
RewriteRule ^([a-z]{2})/p/(.*)$ single.php?lang=$1&hash=$2 [L]
RewriteRule ^([a-z]{2})$ index.php?lang=$1 [L,NC,QSA]

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^?]*)$ index.php?path=$1 [NC,L,QSA]

谢谢

如果我的理解是正确的，这会做你想要的。

Updated .htaccess（与 cmets 一起更好地理解）

RewriteEngine on
RewriteBase /

# If the hostname is a `www` subdomain, redirect to the parent domain
RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
RewriteRule ^(.*)$ http://%1/$1 [R=301,L]

# Internal rewrite of Download request URL to download PHP script
RewriteRule ^download/(.*)$ php/download.php?id=$1 [L]

# If request path is just root `/` (redirect to default language site)
RewriteRule ^$  /en [R=301,L]

# If request path is a language code,
# internally rewrite to index.php with `lang` query paramater
RewriteRule ^([a-z]{2})$ index.php?lang=$1 [L,NC,QSA]

# If request path begins with lang code and has a hash segment,
# internally rewrite to single.php with `lang` and `hash` query parameters
RewriteRule ^([a-z]{2})/p/(.*)$ single.php?lang=$1&hash=$2 [L]

# If request path begins with lang code and has additional segements
RewriteRule ^([a-z]{2})/(.*)$ index.php?lang=$1&path=$2 [NC,L,QSA]

# For every other request path not having a language code,
# if path is not an existing file or directory,
# redirect to a path prefixing default lang code before the requested path
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([^?]*)$  /en/$1 [NC,L,R=301]
