.htaccess CodeIgniter 2.1.1.升级后的htaccess问题

我已经有一个客户网站使用CodeIgniter 1.7大约6年了，现在没有任何问题。然而，最近我将CodeIgniter框架更新为2.1.1，现在.htaccess出现了问题。我已经在日志中确认它没有到达我的控制器，所以我认为这纯粹是一个.htaccess问题

我有几种典型的URL模式：

mysite.com/<page name here>, i.e. mysite.com/faq  
mysite.com/admin/<action here>, i.e. mysite.com/admin/login

现在，很明显，

mysite.com/faq

应该被重写为

mysite.com/page/id/faq

，但它却抛出了404

只需转到

mysite.com

即可成功加载默认控制器，在本例中为主页或相当于

mysite.com/home

。所有的管理员URL都工作正常

mysite.com/page/id/

也能很好地工作

仅作比较，在我升级CodeIgniter之前，6年来一直运行良好的原始

.htaccess

是：

RewriteRule ^((images|styles|scripts|documents)/*.*)$ $1 [L]
RewriteRule ^(admin/*)$ index.php/$1 [L]
RewriteRule ^([a-zA-Z0-9]+)$ page/id/$1
RewriteCond $1 !^(index\.php|robots\.txt|favicon\.ico)
RewriteRule ^(.*)$ index.php/$1 [L]

这个原始版本的行为与我目前尝试使用的版本完全相同。原始文件的重写日志如下所示：

实际的升级过程只是在CodeIgniter框架上，并将文件重新组织到单独的

应用程序

和

系统

文件夹中，除了升级过程中所需的最小更改之外，没有涉及我的实际自定义代码

我已经尝试了10亿个不同的

.htaccess

命令组合，试图让这项功能正常工作，但无法使用相同的配置正确加载“正常”页面和管理页面。最终我的问题是，为什么升级CodeIgniter会神奇地破坏URL重写，但我非常乐意让它再次工作

---

有人有什么建议吗？我想再看看这个

您的.htaccess文件是否位于正确的文件夹中？CodeIgniter使用了几个.htaccess文件，我相信系统和应用程序内部的一个文件称为Deny From All，上面的一个文件中有您的规则。

您的.htaccess文件在正确的文件夹中吗？CodeIgniter使用了几个.htaccess文件，我相信系统和应用程序内部的一个文件说“拒绝来自所有人”，上面的一个文件中有您的规则。

所以我最终得到了另一个论坛的建议。我将

$config['uri_protocol']

从

AUTO

更改为

PATH_INFO

，它神奇地工作了。不过，我确实需要添加一行代码来处理

admin/*

URL格式，因此我最后的

.htaccess

是：

RewriteRule ^(admin/*)$ index.php/$1 [L]
RewriteRule ^([a-zA-Z0-9]+)$ page/id/$1
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ index.php/$1 [L]

为什么不使用路由而不是依赖htaccess？你要我写路线吗？几个小时前我也有同样的问题。直接的解决办法是在我解决这个问题之前不要升级。您重新定义了URL的工作方式了吗？我已经习惯了sitename.com/classfilename/method。@wallyk是的，大约一年前我尝试升级这个网站，但遇到了同样的问题并推迟了升级，但是现在我已经让所有的东西都工作了，除了

/

到

/page/id/

的重写工作，所以我真的很想让它工作。@KarmicDice我觉得不推荐路线。就像我说的，自从我上次接触这个网站已经有好几年了，因为它非常稳定，所以我必须重新查看路线文档并尝试一下，因为这
