Error Passing 32 Bit Integer in URL

I am not sure if this is a CL issue or a PHP or HTTP issue, but when I try to pass the number 4294967295 or anything larger in the URL, I get a 403 error. 

For example:

Code:

https://myurl.com/event?device=4294967295

throws an error but

Code:

https://myurl.com/event?device=4294967294

or

Code:

https://myurl.com/event?device=4294967290

do not. 


Is there a way around this? We use 4294967295 as the serial number for our test devices and need to pass it in the URL. 
Is there a way to encode it, or do I need to make a secial route?

This is a GET parameter and should not affect CI. How do you accept it in the controller? intval() ?

I use $_GET, or the built in request object. Neither work. I tried intval and casting with (string)… passing it as base64 but this isn’t optimal. 

Any number lower than that works fine.

Cannot reproduce.

PHP Code:

<?php

namespace App\Controllers;

class Home extends BaseController
{
    public function index(): string
    {
        $device = $this->request->getGet('device');

        dd($device);
    }
} 


Navigatet to http://localhost:8080/?device=4294967295

$device string (10) "4294967295"

PHP Code:

<?php

namespace App\Controllers;

class Home extends BaseController
{
    public function index(): string
    {
        $device = $this->request->getGet('device');

        dd($device);
    }
} 


Navigatet to http://localhost:8080/?device=4294967295

$device string (10) "4294967295"

My URL has a controller path /event.

What’s your route look like?

Mine is get(‘event’, ‘Event::index);

Can you echo it to the view without casting it as a string?

PHP Code:

$routes->get('event', 'Event::index'); 


PHP Code:

<?php

namespace App\Controllers;

use App\Controllers\BaseController;
use CodeIgniter\HTTP\ResponseInterface;

class Event extends BaseController
{
    public function index()
    {
        $device = $this->request->getGet('device');

        return $device;
    }
} 


Navigate to http://localhost:8080/event?device=4294967295
I see "4294967295".

The values in $_GET are all strings. So you must do something wrong in your code.

My code:

PHP Code:

public function index() {

    $device = $this->request->getGet('device');

    echo $device;
}

How do you explain this?

What is the 403 error page? Is it provided by CI4 (your custom error page)?

Why is it a stdClass when you just echo?

Sorry I was trying out different data types to see what works. My code matches yours on a clean install, and I still get the 403 error. It is the built in CI 4 error page or maybe Plesk. 


 

https://imgur.com/a/uQnAqbK is not the default CI4 error page.

So, the conclusion is that the web server or Web Application Firewall may be returning a 403.
Check with your service provider's technical support.
