Question

我遇到一个奇怪的codeigniter 2问题，我在运行nginx 1.3.8的服务器上遇到这个问题。我的uri段中的破折号被作为下划线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中

function dothis($slug, $id) {
  // echo $slug shows a value of "some_slug_with_dashes"
}

apache webserver上的相同代码按预期工作（破折号仍为破折号）。

我做了一些跟踪和调试，发现在core / Router.php的_parse_routes（）和_set_segments（）函数周围发生了问题。在Router.php的第389行是

return $this->_set_request(explode('/', $val));

在此处回显$ 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
)

将执行追踪到_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
)

如果我回复$this->uri->segments和$this->uri->rsegments的其他调试输出，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
)

我已经检查了我的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。在调用_set_request()之前，php显示正确的值似乎很奇怪，但_set_request() param中修改后的值。

有没有人知道或者有什么可能导致这种情况发生的建议？

更新 - 我的nginx配置如下：

nginx.conf：

                      '$status $body_bytes_sent "$http_referer" '
                      '"$http_user_agent" "$http_x_forwarded_for"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  35;

我发现了问题 - 开发人员错误！原来，部署脚本没有正确地从nginx服务器中删除旧的错误的MY_Router.php文件（该文件在本地也不存在，也不在apache安装上）。抱歉，误报 - codeigniter，nginx和php-fpm按预期工作。开发人员（我）不是这种情况。

codeigniter路由段错误地使用nginx将破折号转换为下划线
