Segment length in uri problem

Hi
I've defined a new route as

Code:

$routes->get('/opendata/(:segment)', 'Tools::openData/$1');

This Tools/openData controller/fuction receives 1 parameter, which is a base64 encoded string of about (average) 500 characters

I've tried with

Code:

https://myApp.com/opendata/dGhpc2lzanVzdGF0ZXN0dGhpc2lzanVzdGF0ZXN0dGhpc2lzanVzdGF0ZXN0dGhpc2lzanVzdGF0ZXN0dGhpc2lzanVzdGF0ZXN0dGhpc2lzanVzdGF0ZXN0

120 characters approx and everything works fine.

Now, I've tried with a real world example which is about 500 char. long and I get a 404 error

1. Any workaround or config setting to allow this ?

2. Any function that could shorten/compress this string (without database, cookies, etc.) univocally so it can work without modifying anything else?

Thanks a lot

What ?
Don't you get 404 when throwing segments of 500 char long?

Ouch .. then how could I debug the 404 error I'm getting? I've enabled debug, debugbar etc. but cannot get anything useful about the 404 it is throwing

Also, the apache server has no extra config or anything weird about it. Same with PHP. Both std installations

Thanks again

Base64 string can contain "/". If your string contains "/", it is not a single segment.
Try "(:any)". But a controller parameter only gets one segment. You need to use "...$params" to get multiple segments.

Wow, you're right. That was it. I've found a / in the 500char string
I've found these functions on internet that seems to work and handle the / = chars

Code:

   
function base64UrlEncode(string $data): string
    {
        $base64Url = strtr(base64_encode($data), '+/', '-_');
        return rtrim($base64Url, '=');
    }
   
    function base64UrlDecode(string $base64Url): string
    {
        return base64_decode(strtr($base64Url, '-_', '+/'));
    }

Thanks again

Try using urlencode.
