Hello,
I need to access a secured websocket server (wss), is PureBasic able to do that?
Thanks

not natively but there are user libs that support websockets

Ok, so there's a couple ways to bypass this constraint. Thanks!
As a PureBasic newbie, I'll probably give a try to Stunnel before messing around with libs...
Also (just to make sure), OpenNetworkConnection() supports server names with path, right? (ex: http(or ws)://server.com/
one/long/path/withf@ncycharacter)

No, it does not. It simply connects to a host using a hostname or IP address. Paths only exist in the environment of a protocol like HTTP(S), (S)FTP, WebDAV and so on. But OpenNetworkConnection() is much more low level.

Oh ok, I see... I guess I have to use SendNetworkString() (string being: /one/long/path/withf@ncycharacter) once connected to host, to access the stream?

No, this is not how this works. It is much more complicated than this. But I am not able to teach it to you here. Let's see if an other user has a good idea to solve your issue.

Ah... Well, I'll try to find more about websocket syntax. Thanks anyway!
BTW, this is where I want to connect, if that helps:
https://github.com/binance-exchange/bin ... streams.md Maybe it's obvious for coding gurus, but it's not for beginners...
edit: Hmm.. Well,
Netzvamp's code (with Stunnel for wss) works great actually!
(did you know websocket servers are case sensitive..?
)
Thank you everybody for the help!

Hu ho... It seems something is wrong with memory, I get errors after a few seconds.
Code:
https://gist.github.com/Netzvamp/8623def14501de15c9e4
(code is 3 years old...)
(...)

Any idea of what's wrong?
Win 7/x64, PureBasic 5.62 (x64)
I'm no expert but I can see some AllocateMemory() functions in loops (especially Repeat/ForEver) and no FreeMemory() function. The program is supposed to run 24/7, isn't it going to fulfill memory?

Anyone know what user libs these are that work with wss?
Thanks
