我有一个现有的简单重写规则,如下所示:
<Directory /path>
RewriteEngine on
RewriteBase /
# if the requested resource does not exist
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# route the uri to a front controller
RewriteRule ^(.*)$ index.php/$1 [L]
</Directory>
这很好,但我想做以下两件事之一。在检测客户端 accept-language 标头的基础上,我想
(i)将检测到的语言设置为脚本可以使用的环境变量或
(ii)重写请求,使 URL 以语言代码开头(例如 www.example.com/en/some/resource)
为了实现(i),我定义了以下规则:
<Directory /path>
RewriteEngine on
RewriteBase /
# if the requested resource does not exist
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# if the users preferred language is supported...
RewriteCond %{HTTP:Accept-Language} ^.*(de|es|fr|it|ja|ru|en).*$ [NC]
# define an environmental variable PREFER_LANG
RewriteRule ^(.*)$ - [env=PREFER_LANG:%1]
# route the uri to a front controller
RewriteRule ^(.*)$ index.php/$1 [L]
</Directory>
我尝试了几种变化,但 PREFER_LANG 没有在 $_SERVER 中定义,也无法通过 getenv 检索。
关于实施 (ii)... 只能说它很混乱。如果我找不到答案,我会发布它。
有人能给我建议吗?谢谢!

当然可以使用来设置环境变量mod_rewrite
。使用以下配置:
RewriteEngine on
RewriteLog /var/log/httpd/rewrite.log
RewriteLogLevel 5
# if the requested resource does not exist
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# if the users preferred language is supported...
RewriteCond %{HTTP:Accept-Language} ^.*(de|es|fr|it|ja|ru|en).*$ [NC]
# define an environmental variable PREFER_LANG
RewriteRule ^(.*)$ - [env=PREFER_LANG:%1]
# route the uri to a front controller
RewriteRule ^(.*)$ /cgi-bin/serverfault.cgi?q=$1 [PT]
其中,serverfault.cgi
只是一个调用的 shell 脚本env
。它工作得很好:
$ curl -s -H 'Accept-language: de' http://localhost/serverfault/somefile |
grep PREFER
PREFER_LANG=de
你RewriteLog
看起来怎么样?你应该看到类似这样的内容:
init rewrite engine with requested uri /serverfault/foo.html
applying pattern '^(.*)$' to uri '/serverfault/foo.html'
RewriteCond: input='/serverfault/foo.html' pattern='!-f' => matched
RewriteCond: input='/serverfault/foo.html' pattern='!-d' => matched
RewriteCond: input='en-US,en;q=0.8' pattern='^.*(de|es|fr|it|ja|ru|en).*$' [NC] => matched
setting env variable 'PREFER_LANG' to 'en'
applying pattern '^(.*)$' to uri '/serverfault/foo.html'
rewrite '/serverfault/foo.html' -> '/cgi-bin/serverfault.cgi?q=/serverfault/foo.html'
split uri=/cgi-bin/serverfault.cgi?q=/serverfault/foo.html -> uri=/cgi-bin/serverfault.cgi, args=q=/serverfault/foo.html
forcing '/cgi-bin/serverfault.cgi' to get passed through to next API URI-to-filename handler

根据评论PHP 手册有可能。PHP 是作为模块还是 CGI 集成的?
