[SOLVED] How do I create a websocket connection in Python?

How do I create a websocket connection in Python?

I am trying to create a websocket connection with following code (just to make a test connection):

async def webSocket():

async with websockets.connect("wss://push1-v2.kucoin.com") as test:
    await test.send("/api/v1/bullet-public")
    result = await test.recv()
    print(result)

if __name__ == '__main__':
asyncio.get_event_loop().run_until_complete(webSocket())

The result is supposed to be a json response like this:

{
"code": "200000",
"data": {

    "instanceServers": [
        {
            "endpoint": "wss://push1-v2.kucoin.com/endpoint",
            "protocol": "websocket",
            "encrypt": true,
            "pingInterval": 50000,
            "pingTimeout": 10000
        }
    ],
    "token": "vYNlCtbz4XNJ1QncwWilJnBtmmfe4geLQDUA62kKJsDChc6I4bRDQc73JfIrlFaVYIAE0Gv2--MROnLAgjVsWkcDq_MuG7qV7EktfCEIphiqnlfpQn4Ybg==.IoORVxR2LmKV7_maOR9xOg=="
}

}

Instead when I execute the code I get following error:

for res in _socket.getaddrinfo(host, port, family, type, proto, flags):
socket.gaierror: [Errno 11001] getaddrinfo failed

Is there maybe a setting I would have to change to my python set up? I use version 3.9.

Solution

The target for that first POST (/api/v1/bullet-public) is the API HTTPS which is https://api.kucoin.com/

You can manually try it by using your command line or terminal:

curl -i -X POST https://api.kucoin.com/api/v1/bullet-public
