codeigniter如何支持中文URL?

第一步把config.php中的

$config['permitted_uri_chars'] = 'a-z 0-9~%.:_\-';

 替换成

$config['permitted_uri_chars'] ='a-z 0-9~%.:_-u4e00-u9fa5';

 第二步在application的libraries下增加一个My_URI.php文件，文件内容如下

<?php
class MY_URI extends CI_URI {
        function _filter_uri($str)
    {
        if ($str != '' AND $this->config->item('permitted_uri_chars') != '')
        {
            $str = urlencode($str);
            if ( ! preg_match("|^[".preg_quote($this->config->item('permitted_uri_chars'))."]+$|i", $str))
            {
                exit('The URI you submitted has disallowed characters.');
            }
            $str = urldecode($str);
        }
        return $str;
    }

} 
?>

 

这样就ok了。
