在 URL 中强制用户的语言首选项 - 重写规则？

Question

我想在 URL 中指定用户的语言首选项。 如果缺少的话，是否可以使用 .htaccess 重写规则将段添加到 url 中。

URL 通常应具有此结构

mysite.com/directory/en
mysite.com/directory/fr
mysite.com/directory/en/about_us.php
mysite.com/directory/fr/about_us.php

如果缺少语言，我想自动将 url 转换为默认英语。

mysite.com/directory                
>> should be transformed to mysite.com/directory/en 

mysite.com/directory/about_us.php   
>> should be transformed to mysite.com/directory/en/about_us.php

示例：

RewriteEngine On 

# don't redirect 

RewriteCond %{REQUEST_FILENAME} !-f 
RewriteCond %{REQUEST_FILENAME} !-d
RewriteCond %{REQUEST_FILENAME} !-l


RewriteRule !^(fr|en)/ /... something...

# redirect 
RewriteRule ^(.+)$ index.php?url=$1 [QSA,L]

有人可以帮助我准确理解迈克尔的解决方案是什么吗如果我移动到新的子目录，如何更改 htaccess

mysite.com/directory                
>> should be transformed to mysite.com/directory/en 

mysite.com/directory/subdirectory/about_us.php   
>> should be transformed to mysite.com/directory/en/subdirectory/about_us.php

...

# If the URL doesn't match /xx/otherstuff
# !^([a-z]{2}) - exactly two alpha characters not at the beginning of the string
# (.*)$ - store the result found above as $1
RewriteCond %{REQUEST_URI} !^([a-z]{2}/)(.*)$

# Rewrite to /en/
# ^(.+)$ - begins with 
# http://%{HTTP_HOST}/en/$1 - replace with http://hostname/en
# L = Last Stop the rewriting process immediately and don't apply any more rules.
# R = Redirect Forces an external redirect, optionally with the specified HTTP status    code
# QSA - Query String Append - forces the rewrite engine to append a query string part of the substitution string to the existing string
RewriteRule ^(.+)$ http://%{HTTP_HOST}/en/$1 [L,R,QSA]

Answer 1

使用 RewriteCond 查找 URI 开头的 2 个字母语言代码：

RewriteEngine On

RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# If the URL doesn't match /xx/otherstuff
RewriteCond %{REQUEST_URI} !^([a-z]{2}/)(.*)$
# Rewrite to /en/
RewriteRule ^(.+)$ http://%{HTTP_HOST}/en/$1 [L,R,QSA]

如果您使用 2 个以上字符语言代码（例如最多 4 个），请使用 [az]{2 ,4} 相反。
