遇到 PHP 错误

严重性:警告

消息:parse_url(/%22**) [function.parse-url]:无法解析 URL

Message: parse_url(/%22**) [function.parse-url]: Unable to parse URL

Filename: core/URI.php

遇到错误

您提交的 URI 包含不允许使用的字符.

The URI you submitted has disallowed characters.

这是我在 URI.php 中的所有代码

This is all the code i have in URI.php

private function _detect_uri()
{
    if ( ! isset($_SERVER['REQUEST_URI']) OR ! isset($_SERVER['SCRIPT_NAME']))
    {
        return '';
    }

    $uri = $_SERVER['REQUEST_URI'];
    if (strpos($uri, $_SERVER['SCRIPT_NAME']) === 0)
    {
        $uri = substr($uri, strlen($_SERVER['SCRIPT_NAME']));
    }
    elseif (strpos($uri, dirname($_SERVER['SCRIPT_NAME'])) === 0)
    {
        $uri = substr($uri, strlen(dirname($_SERVER['SCRIPT_NAME'])));
    }

    // This section ensures that even on servers that require the URI to be in the query string (Nginx) a correct
    // URI is found, and also fixes the QUERY_STRING server var and $_GET array.
    if (strncmp($uri, '?/', 2) === 0)
    {
        $uri = substr($uri, 2);
    }
    $parts = preg_split('#?#i', $uri, 2);
    $uri = $parts[0];
    if (isset($parts[1]))
    {
        $_SERVER['QUERY_STRING'] = $parts[1];
        parse_str($_SERVER['QUERY_STRING'], $_GET);
    }
    else
    {
        $_SERVER['QUERY_STRING'] = '';
        $_GET = array();
    }

    if ($uri == '/' || empty($uri))
    {
        return '/';
    }

    $uri = parse_url($uri, PHP_URL_PATH);

    // Do some final cleaning of the URI and return it
    return str_replace(array('//', '../'), '/', trim($uri, '/'));
}

推荐答案

CodeIgniter 检查所有 URI 段中是否存在不允许的字符.这是通过将允许的字符列入白名单来实现的.可以在 $config['permitted_uri_chars'] 变量中的 /system/application/config/config.php 中检查哪些是允许的.permitted_uri_chars 是 CodeIgniter 在您的 URI 中接受的字符.默认值设置为类似的值.

CodeIgniter checks all URI segments for disallowed characters. This happens by white listing allowed characters. Which ones are allowed can be checked in /system/application/config/config.php in the $config['permitted_uri_chars'] variable. permitted_uri_chars are the characters that CodeIgniter accepts in your URI.The default value is set to something like.

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

默认情况下只允许这些:a-z 0-9~%.:_-

By default only these are allowed: a-z 0-9~%.:_-

留空以允许所有字符——但前提是你疯了.

Leave blank to allow all characters -- but only if you are insane.

%22 用于 ".您可以将其添加到 permitted_uri_chars 列表中.

%22 comes for ".You can add this in permitted_uri_chars list.
