The URI you submitted has disallowed characters...

XAMPP Version: 1.8.1

codeigniter 2.1.3

设置完虚拟主机后报 The URI you submitted has disallowed characters  错误

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

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

但是我改动后并没有发现什么效果 起作用的是下面的函数。

 CI_URI 做一下改动即可 

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

好像这个问题都跟xampp有关系似的。

具体原因不是非常清楚带有时间研究。
