htaccess 和Code Igniter中的路由问题
我花了过去 3 个小时试图解决这个问题，但总是有一个部分不起作用，所以如果有人能帮助我，我将不胜感激。
我试图在 htaccess 中实现的目标是： 删除尾部斜杠并强制执行 www.
因此，这 4 个示例需要显示相同的结果：
#1. www.mysite.com/products/show/
#2. www.mysite.com/products/show
#3. mysite.com/products/show/
#4. mysite.com/products/show
它们都需要显示 #2，因为这是正确的。
有很多示例和解决方案可以做到这一点，并且我可以让它发挥作用，但是！我也在这个控制器上使用一条路线，如下所示： $route['产品/(:any)'] = "产品/show/$1";
再一次，htaccess 和路由都工作正常，当 (:any) 包含斜杠时就会出现问题，例如 foo-bar。然后#3 突然失败，网站根本无法加载，并且出于某种奇怪的原因，URL 更改为 www.domain.tld/products/foo-bar （是的，它实际上打印出 domain.tld，我没有将其用作例如，该域当然不是有效的域。）
以下是我目前在 htaccess 中拥有的内容，请记住，为了强制执行 www，我不能！对实际域名进行硬编码，因为将有多个域指向该文档根目录，所有这些域都使用相同的脚本构建。

RewriteEngine On
RewriteBase /
#RewriteRule ^(welcome(/index)?|index(\.php)?)/?$ / [L,R=301]
RewriteCond $1 !^(index\.php|images|doc)
RewriteRule ^(.*)/index/?$ $1 [L,R=301]
# Removes trailing slashes (prevents SEO duplicate content issues)
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.+)/$ $1 [L,R=301]
# Enforce www
RewriteCond %{HTTP_HOST} ^([^.]+)\.([^.]+)$ [NC]
RewriteRule ^(.*)$ http://www.%1.%2/$1 [R=301,L]
感谢您的帮助，

I have spent the last 3 hours trying to get this right, but there is always one part that doesnt work, so i would be so grateful if someone could help me out.
What im trying to achieve in htaccess is:
To remove trailing slashes, and enforce www.
So these 4 examples need to show the same result:
#1. www.mysite.com/products/show/
#2. www.mysite.com/products/show
#3. mysite.com/products/show/
#4. mysite.com/products/show
They all need to show #2, as that is the correct on.
There are a lot of examples and solutions out there, to do this, and i get it to work, BUT! im also using a route on this controller, looking like this:
$route['products/(:any)'] = "products/show/$1";
Once again, it is all working, both the htaccess and the route, the problem arises when (:any) contains a slash, example foo-bar. Then suddenly #3 fails and the site just doesnt load at all and for some weird reason the url changes to www.domain.tld/products/foo-bar (yes, it actually prints out domain.tld, im not using it as an example. and that domain is of course not even a valid domain.)
Below is what i currently have in my htaccess, please do keep in mind that for the enforce of www, i can not! hard code the actual domain name, because there will be more than one domain pointing to this document root, all using the same script im building.

WWW 问题：也许您需要 mysite.com 的 CNAME 记录才能指向 www.mysite.com？这是我对给定信息的最佳猜测。
URI 路由：请记住，当 /products/(:any) 中的 (:any) 包含斜杠时，路由不再是 /products/(any).. 它是 /products/(any)/(something_else) 。这将作为您的 URL 的另一个段进行处理。
如果斜杠不是路由的一部分，则您将无法在 URL 中使用带有斜杠的内容。如果您只需要在 URL 中传递，您可以执行某种编码/解码。
至于为什么它路由到domain.tld，我不知道。 :)
WWW Problem: Perhaps you need a CNAME record for mysite.com to point to www.mysite.com? That's my best guess with the given information.
URI Routing: Keep in mind, that when (:any) in /products/(:any) contains a slash, the route is no longer /products/(any).. it is /products/(any)/(something_else). This is handled as another segment to your URL.
You won't be able to use something in your URL with a slash in it if the slash is not part of your routing. You could do some kind of encoding/decoding if you just need that passed in the URL.
As to why it's routing to domain.tld, I have no idea. :)
