[titoff002]

Hello,

I would like to use elephantio with wss, but it does not work.

try{
        $client = new Client(new Version2X('wss://'.$url));

        $client->initialize();

        $client->close();
      }catch(\Exception $e){
        Log::debug('<<<ERR curlWws:'.print_r($e->getMessage(),true));
      }

I have the following error message:

:An error occurred while trying to establish a connection to the server

how can I fix this problem ??

Thanks.

Could you dump the getErrorMessage() from the exception ? Thanks.

This doesn't give me what I want. What I want is var_dump($e->getErrorMessage()), which (for some reasons) doesn't appear in your print_r.

[titoff002]

PS: Don't work with laravel, but work fine with socketIO/javascript

[Taluu]

That is still not what I want.

<?php
use ElephantIO\Client;
use ElephantIO\Engine\SocketIO\Version2X;
use ElephantIO\Exception\ServerConnectionFailureException;

try {
    $client = new Client(new Version2X('wss://'.$url));
    $client->initialize();

    $client->close();
} catch (ServerConnectionFailureException $e) {
    dump($e->getErrorMessage());
} catch (\Exception $e){
    Log::debug('<<<ERR curlWws:'.print_r($e->getMessage(),true));
}

something along those lines. I need the result of the dump (or var_dump, print, ... whatever)

[titoff002]

I 've replace this line
$result = @file_get_contents($url, false, stream_context_create($context));

By
$result = file_get_contents($url, false, stream_context_create($context));

And i have a new error message :

"file_get_contents(): Unable to find the wrapper "wss" - did you forget to enable it when you configured PHP?"

[Taluu]

The error is pretty explicit, your php configuration doesn't seem to know the wss protocol.

You either need to declare the protocol (through the https://www.php.net/manual/en/class.streamwrapper.php class), or you could use another protocol such as http or https.

[titoff002]

Thanks,

I'm not understand for declare "wss" protocol : have you a code ?

You speak french ?
