为什么我的 URL 在使用 CodeIgniter 框架时只能在目录前面带有问号的情况下使用？

Question

我在 PHP 框架 CodeIgniter 的 .htaccess 中使用以下代码。

<IfModule mod_rewrite.c>

RewriteEngine On
RewriteBase /

### Canonicalize codeigniter URLs

# If your default controller is something other than
# "welcome" you should probably change this
RewriteRule ^(welcome(/index)?|index(\.php)?)/?$ / [L,R=301]
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
# If you have subdomains, you can add them to 
# the list using the "|" (OR) regex operator
#RewriteCond %{HTTP_HOST} !^(www|subdomain) [NC]
#RewriteRule ^(.*)$ http://www.domain.tld/$1 [L,R=301]

# Enforce NO www
#RewriteCond %{HTTP_HOST} ^www [NC]
#RewriteRule ^(.*)$ http://domain.tld/$1 [L,R=301]

###

# Removes access to the system folder by users.
# Additionally this will allow you to create a System.php controller,
# previously this would not have been possible.
# 'system' can be replaced if you have renamed your system folder.
RewriteCond %{REQUEST_URI} ^system.*
RewriteRule ^(.*)$ /index\.php/$1 [L]

# Checks to see if the user is attempting to access a valid file,
# such as an image or css document, if this isn't true it sends the
# request to index.php
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index\.php/$1 [L]

如果我输入网址 http://linuxservers.org/articles 文章页面不会加载（索引做）。但是，如果我输入 linuxservers.org/?articles 或 /?/articles，页面就会加载。我不明白。

除此之外，如果我将上面代码中的最后一行更改为

    RewriteRule ^(.*)$ index\.php/?$1 [L]

OR

    RewriteRule ^(.*)$ index\.php?/$1 [L]

（将 /articles 重定向到 /?articles 或 /?/articles），则会加载页面。 index.php/articles 也会加载页面，这是 CodeIgnitor 的默认格式。

希望这是有道理的，如果没有，请问我问题。期待您的意见。

您从哪里获取 .htaccess 文件？ CodeIgniter wiki 的最后一行为：

RewriteRule ^(.*)$ index.php?/$1 [L]

这是您的工作选项之一。
