Question

I find this in official documentation

enter image description here

Is it possible to somehow implement sending messages to the server (I use private socket server)?

I can't find any solutions for resolve this problem, all answers is very outdated.

Answer 1

It is not directly possible to call the SignalR server method in Java, because SignalR is based on NET library, mainly used in Real time communication in the NET environment. Java and NET is two different programming languages and platforms, with limited interoperability between them. You can use methods such as HTTP or WebSocket to send requests or messages to communicate with the server.

Answer 2

The answer is yes. There are 3 modes in azure signalr service.

The tips you shared, it just tell us, if you are using serverless or classic mode to connect azure signalr, your java clients can't call the hub methods.

It depends on how you configure Azure Signalr Service in asp.net Core.

Here is a sample for you.

hubConnection.send("BroadcastMessage", input);
