how a client can get hub connection id of specific client using signalR

Question

User-1461245458 posted

I am working on chat application, I am able to do broadcast message to all client,

but I want to send message to any specific client. I can get all connected clients hub connection Id, but how can I identify which hub connection id is used for a particular client.

So I want to store any unique data created at server side code with hub connection id when client logins. But I am not able to store any unique key which is in session from Controller to hub class.

I am using MVC5. Please suggest me any solution for it.

Hi vinodkus,

From your description, you  want to get client connection id to call the special client instead of broadcast all clients.

As far as I know, You could use Context.ConnectionId in the Hub class scope, it means current client connection id.

More details, please refer the API guides:

Thanks Cathy for your response.

Actually I find my solution with another way,

Actually I had to pass any specific user information like userid at the time of login and make a connection with hub connection id. So that If I call any friend with userid then

on the basis of userid I can get his hub connection id and can call him.

But I have one issue how to check that some message came at specific client and message window will automatically open there.
