多语言网站的.htaccess规则

Question

我正在重新设计PHP多语言网站的URL(en | es | de | fr | ru).网站的URL是这样的:

www.mysite.com/page
www.mysite.com/page/subpage1
www.mysite.com/page/subpage1/subpage2
www.mysite.com/page/subpage1/subpage2/subpage3

最多四个级别的子目录(产品,子产品等).语言作为GET参数传递:

www.mysite.com/page?lang=es

要么

www.mysite.com/page/subpage1/subpage2?lang=de

目前的.htaccess是这样的:

Options +FollowSymlinks +MultiViews -Indexes
RewriteEngine on

RewriteBase /

# Redirect all versions of homepage to www.mysite.com
RewriteCond %{REQUEST_URI} ^/index\.html$
RewriteRule ^index.html$ http://www.mysite.com/ [R=301,L]

# Redirect non-www to www traffic
RewriteCond %{HTTP_HOST} !^(www\.mysite\.com)?$
RewriteRule (.*) http://www.mysite.com/$1 [R=301,L]

RewriteCond %{SCRIPT_FILENAME} !-d
RewriteCond %{SCRIPT_FILENAME} !-f

#Remove php extension
RewriteCond %{REQUEST_URI} ^(.*).php$
RewriteRule ^(.*)$ %1 [R=301,QSA] 

#Here I have a lot of 301 redirections, I ommit them for this example

# First level redirections
RewriteRule ^([0-9a-zA-Z\-\_]+)$ view?page=$1 [L,QSA]

# Second level redirections
#RewriteRule ^(page1|page2|page3)\/([0-9a-zA-Z\-\+\_\,\.\(\)]+)$ view?page=$1&subpage1=$2 [L,QSA]

# Third level redirections
RewriteRule ^([0-9a-zA-Z\-\_]+)\/([0-9a-zA-Z\-\+\_\,\.\(\)]+)\/([0-9a-zA-Z\-\_]+)$ view?page=$1&subpage1=$2&subpage2=$3 [L,QSA]

# Fourth level redirections
RewriteRule ^([0-9a-zA-Z\-\_]+)\/([0-9a-zA-Z\-]+)\/([0-9a-zA-Z\-]+)\/([0-9a-zA-Z\-]+)$ view?page=$1&subpage1=$2&subpage2=$3&subpage3=$4 [L,QSA]

现在我想将整个站点重定向到带有前置语言子目录的URL,如果URL(GET)中没有语言参数,就像这样(默认英语):

www.mysite.com/page -> www.mysite.com/en/page
www.mysite.com/page/subpage1 -> www.mysite.com/en/page/subpage1

如果在URL中传递GET参数,我想重定向到正确的URL:

www.mysite.com/page?lang=es -> www.mysite.com/es/page
www.mysite.com/page/subpage1?lang=es -> www.mysite.com/es/page/subpage1

我已经回顾了其他类似的问题,但所有这些问题都基于301重定向和最后一个参数([R = 301,L]),我担心Last对我无效.

我有几个问题:

1. 有没有办法让.htaccess更容易,没有每个级别的规则？
2. 如果URL中没有传递lang GET参数,如何将我的整个站点重定向到www.mysite.com/en？
3. 如何根据lang GET参数重定向到正确的本地化站点(www.mysite.com/page?lang=es - >重定向到www.mysite.com/es/page)

提前致谢

您需要这些附加规则：

# lang supplied in query string
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{QUERY_STRING} ^lang=([a-z]{2})(?:&|$) [NC]
RewriteRule !^[a-z]{2}/ /%1/%{REQUEST_URI}? [L,NC,R=301]

# lang not supplied in query string
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{QUERY_STRING} !^lang=.+(&|$) [NC]
RewriteRule !^en/ /en/%{REQUEST_URI} [L,NC,R=301]
