I need to access the query parameter dict from Django Channels.

The url may look like this: ws://127.0.0.1:8000/?hello="world"

How do I retrieve 'world' like this: query_params["hello"]?

Updated for Channel 3:

from urllib.parse import parse_qs

# Types
class Scope(TypedDict):   
    query_string: bytes

scope: Scope
query_params: Dict[str, List[str]]

# Parse query_string
query_params = parse_qs(scope["query_string"].decode())

print(query_params["access_token"][-1])

If you were doing this a lot, you could put it in a middleware and wrap your ASGI application in it. Something like:

class QueryParamsMiddleware(BaseMiddleware):
    async def __call__(self, scope, receive, send):
        scope = dict(scope)

        scope["query_params"] = parse_qs(scope["query_string"].decode())

        return await super().__call__(scope, receive, send)
