Question

我正在尝试重写/重定向传入的请求，以便它们始终以语言代码为前缀，但希望保留最初请求的路径：

example.org/de/     -> rewrite to example.org?lang=de
example.org         -> redirect to example.org/de/ which will then be rewritten
                       to example.org?lang=de
example.org/en/     -> rewrite to example.org?lang=en
example.org/foo/bar -> redirect to example.org/de/foo/bar wich will 
                       then be rewritten to example.org/foo/bar?lang=de

这些是我对此的想法：

RewriteBase /

# No 'lang' key in query string 
RewriteCond %{QUERY_STRING} !lang=(en|de) 

# AND request_uri does not start with 'en' or 'de'
RewriteCond %{REQUEST_URI} !^(en|de) 

# Redirect to lang prefixed uri while keeping the initial uri
RewriteRule ^(.*)$ de/%{REQUEST_URI} [L,R=301,QSA]

# Add language prefix as query parameter
RewriteRule ^(en|de) ?lang=$1 [L,QSA]

此外，我想保留传入请求的任何查询字符串，并将其附加到重定向/重写的uri。实际上我的想法对我来说听起来很合理，但我得到了无休止的重定向。如果你能指出我正确的方向，我会很高兴，因为我已经失去了几个小时和几个小时

最后在anubhava的帮助下，我可以设法解决整个问题，并希望分享最终的解决方案

# 1) Prefix ALL request uris with /<lang>/. Depending on the `Accept-Language` 
#    header 'de' or the default 'en' is used as prefix.
# 2) Rewrite real files by stripping off the /<lang>/ prefix but still add 
#    the ?lang=<lang> query parameter
# 3) Add a trailing slash and append ?lang=<lang> query parameter


RewriteEngine On

RewriteBase /

# No 'lang' key in query string and 'de' as accepted language header.
# Redirect to 'de' prefixed uri
RewriteCond %{QUERY_STRING} !lang=(en|de) [NC]
RewriteCond %{HTTP:Accept-Language} (de) [NC]
RewriteRule !^(en|de)(/.*)?$ de%{REQUEST_URI} [L,NC,R]

# Redirect anybody without 'de' as accepted language to the 'en' version
RewriteCond %{QUERY_STRING} !lang=(en|de) [NC]
RewriteRule !^(en|de)(/.*)?$ en%{REQUEST_URI} [L,NC,R]

# Strip lang prefix in case this a real file
RewriteCond %{REQUEST_URI} ^/(en|de)(/.*)$ [NC]
RewriteCond %{DOCUMENT_ROOT}%2 -f 
RewriteRule ^(en|de)(/.*)$ $2?lang=$1 [L,NC]

# Add trailing slash to those request which make it till here
RewriteRule ^(en|de)(/.*)?/?$ $2/?lang=$1 [L,NC,QSA]

非常感谢你的帮助！

您可以遵守以下规则：

RewriteEngine On

# No 'lang' key in query string 
RewriteCond %{QUERY_STRING} !lang=(en|de) [NC]
# Redirect to lang prefixed uri while keeping the initial uri
RewriteRule !^(en|de)/ /de/%{REQUEST_URI} [L,NC,R=301]

RewriteRule ^(en|de)(/.*)?$ $2?lang=$1 [L,NC,QSA]

清除浏览器缓存后进行测试。
