List connected clients

[Charlyx12]

Hi, is there a way to list all the clients that are connected to the server? I mean, their names for example.

[AndreasHeine]

probably the binary server:

opcua-asyncio/asyncua/server/server.py

Line 90 in 729ef89

self.bserver: Optional[BinaryServer] = None

opcua-asyncio/asyncua/server/binary_server_asyncio.py

Line 112 in 729ef89

self.clients = []

For example, in this case theres a client connected to the server, when I print doing print(server.bserver.clients) i get the following result:

[OPCUAProtocol(('127.0.0.1', 56703), InternalSession(name:('127.0.0.1', 56703), user:User(role=<UserRole.Anonymous: 1>, name=None), id:NodeId(Identifier=11, NamespaceIndex=0, NodeIdType=<NodeIdType.TwoByte: 0>), auth_token:NodeId(Identifier=1001, NamespaceIndex=0, NodeIdType=<NodeIdType.FourByte: 1>)))]

I had the idea to obtain the names by processing the result as a string and searching for the 'name' field, but i dont think its a great solution. Is there another way to do that or do you think this could be a possible solution?

Thanks

Either you stringify the result and use regex or you have to create a function, which filters out the informations you want.

ok, thank you so much. :)

Either way, I would recommened that you should use 3 clients, if you want to built such a function. This avoids pitfalls.

I was able to get the names by using regex:
name=re.findall("(?<=name\=\')(\w+)",str(server.bserver.clients[server.bserver.clients.index(cli)]))
where cli is the iterator variable used in a for loop to move through server.bserver.clients list

However, I found another way to get the same results:
name=server.bserver.clients[server.bserver.clients.index(cli)].processor.session.user.name

If you are also interested in getting the role, you could use:
role = server.bserver.clients[server.bserver.clients.index(cli)].processor.session.user.role.name
