我在运行 nginx 1.3.8 的服务器上遇到了一个奇怪的 codeigniter 2 问题。我的 uri 段中的破折号作为下划线被路由到我的控制器方法：
网址：http ://myserver.com/dothis/some-slug-with-dashes/someid
在 routes.php 中：
$route['^dothis/(.+)/(.+)$'] = "mycontroller/dothis/$1/$2";
在 mycontroller.php
function dothis($slug, $id) {
// echo $slug shows a value of "some_slug_with_dashes"
}
apache 网络服务器上的相同代码按预期工作（破折号仍然是破折号）。
我做了一些跟踪和调试，发现问题出现在 core/Router.php 的 _parse_routes() 和 _set_segments() 函数周围。Router.php 的第 389 行是
return $this->_set_request(explode('/', $val));
在这里回显 $val 的值表明它是/mycontroller/dothis/some-slug-with-dashes/F3e.
输出explode()的值显示
Array
(
[0] => mycontroller
[1] => dothis
[2] => some-slug-with-dashes
[3] => someid
)
跟踪执行到 _set_request()，如果我插入一行来输出$segments参数的值：
function _set_request($segments = array())
{
echo "\n<br/>_set_request() segments: <pre>";print_r($segments);echo "</pre>"; // inserted debug
$segments = $this->_validate_request($segments);
...
}
我得到的调试输出是
_set_request() segments:
Array
(
[0] => mycontroller
[1] => dothis
[2] => some_slug_with_dashes
[3] => someid
)
如果我回显额外的调试输出$this->uri->segments，$this->uri->rsegments我会得到：
// $this->uri->segments
Array
(
[0] => dothis
[1] => some-slug-with-dashes
[2] => someid
)
// $this->uri->rsegments
Array
(
[0] => mycontroller
[1] => dothis
[2] => some_slug_with_dashes
[3] => someid
)
我检查了我的 codeigniter uri 允许的字符，这是默认设置。我还检查了 nginx 和 fastcgi 参数，它们是基本规则。我还搜索了 stackoverflow 问题和 nginx 论坛。php 在调用之前显示正确的值_set_request()但在_set_request() param.
有没有人知道或有一些关于可能导致这种情况发生的建议的想法？
更新 - 我的 nginx 配置如下：
nginx.conf：
