Question

以下是我的网址请求

http://test.com?leavingfrom=BOM&goingto=DEL&travel=DOM&_token=gclligMoBzOHW4wwruDShklxbOh3SjsKTWRvWFK0&Default=O&leavingfrom1=Mumbai+%28BOM%29&goingto1=New+Delhi+%28DEL%29&depart=16-02-2017&arrive=&class=E&adults=1&child=0&infants=0
此网址正在发生跨网站脚本，如下所示。新参数会在网址中添加为＆＃39; -alert - ＆＃39; = 1并传递给下一页

如果添加新参数，如何停止跨站点脚本

Answer 1

您可以将此类用作中间件

class XSSProtection
{
    /**
     * The following method loops through all request input and strips out all tags from
     * the request. This to ensure that users are unable to set ANY HTML within the form
     * submissions, but also cleans up input.
     *
     * @param Request $request
     * @param callable $next
     * @return mixed
     */
    public function handle(Request $request, \Closure $next)
    {
        if (!in_array(strtolower($request->method()), ['put', 'post'])) {
            return $next($request);
        }

        $input = $request->all();

        array_walk_recursive($input, function(&$input) {
            $input = strip_tags($input);
        });

        $request->merge($input);

        return $next($request);
    }
}
