Send headers in Websockets connection request from Python client

Question

What is the correct method / syntax for adding headers to a websocket connection request using Python Websockets ?

The server I'm trying to connect to requires headers in the connection request for authentication

async def connect():
    async with websockets.connect("wss://site.com/ws") as websocket:
        response = await websocket.recv()
        print(response)

    # eg. does not work:
    async with websockets.connect(f"wss://site.com/ws, header={headers}") as websocket:
    async with websockets.connect(f"wss://site.com/ws, extra_headers:{headers}") as websocket:

Similar question was asked here but did not answer the core of the question: How to send 'Headers' in websocket python

Answer 1

According to documentation, you can pass headers in additional_headers param of connect() function. Details here.

So code should look something like this:

async def connect():
    async with websockets.connect("wss://site.com/ws", additional_headers=headers) as websocket:
        response = await websocket.recv()
        print(response)
