用CI框架时,有时候会遇到这么一个问题,打开网页,只显示 Disallowed Key Characters 错误提示。有人说 url 里有非法字符。但是确定 url 是纯英文的,问题还是出来了。但清空浏览器历史记录和cookies后。 刷新就没问题了。有时候。打开不同的浏览器。有的浏览器会有问题。有的就不会。
解决 CodeIgniter 框架应用中,出现Disallowed Key Characters错误提示的方法。找到/system/core文件夹下的Input文件,将下面的代码:
function _clean_input_keys($str)
{
if ( ! preg_match("/^[a-z0-9:_\/-]+$/i", $str))
{
exit('Disallowed Key Characters.');
}
// Clean UTF-8 if supported
if (UTF8_ENABLED === TRUE)
{
$str = $this->uni->clean_string($str);
}
return $str;
}
改为:
function _clean_input_keys($str)
{
$config = &get_config('config');
if ( ! preg_match("/^[".$config['permitted_uri_chars']."]+$/i", rawurlencode($str)))
{
exit('Disallowed Key Characters.');
}
// Clean UTF-8 if supported
if (UTF8_ENABLED === TRUE)
{
$str = $this->uni->clean_string($str);
}
return $str;
}
