How to open multiple clients?

[exostieStevelo]

Do you have something example to open multiple clients?

I try something like this:

async def hello(location):
    async with websockets.connect(location) as websocket:
        name = input("What's your name? ")
        await websocket.send(name)
        print("> {}".format(name))

        greeting = await websocket.recv()
        print("< {}".format(greeting))

asyncio.get_event_loop().run_until_complete(hello(locationA))
asyncio.get_event_loop().run_until_complete(hello(locationB))

I will get errors:

error connect Malformed HTTP message
error connect Malformed HTTP message
error connect Malformed HTTP message
error connect Malformed HTTP message
error connect Malformed HTTP message
error connect Malformed HTTP message
error connect Malformed HTTP message
error connect Malformed HTTP message

There isn't enough info here for me to help you.

Your code runs the connections to locationA and locationB one after the other. You don't have multiple clients connected in parallel in this example. So I don't understand what you mean by "multiple clients".

I don't know what locationA and locationB are, but they're probably not a WebSocket server that accepts your connection, because they don't even return a valid HTTP response (based on "Malformed HTTP message" — you didn't say where you were seeing that message).

@aaugustin thanks you reply. I went clients connected in parallel at the same time.
in this example only one it will be fine.

asyncio.get_event_loop().run_until_complete(hello(locationA))

example:

locationA = 'wss://localhost:443/loga'
locationA = 'wss://localhost:443/logb'

That's really a question about asyncio, not about websockets. Take a look at asyncio.ensure_future or asyncio.wait and related APIs.

(I'm still unsure of how that question is related to the error messages you showed in your original message.)

@aaugustin thanks. I will try to dig more about asyncio.
