从Web-> Web api->控制台应用程序进行通讯并再次返回的最佳方法是什么？

Question

I'm starting up a little code project to learn from the process, but I am not sure what's the best way of communicating between the different parts.

• First, I have a pure html/js client where the users need to get live updates frequently.
• Secondly, I'm considering having a web api application running to provide data.
• Thirdly I have a console application running, that needs to communicate with the web api application.

So I'm thinking about using WebSockets all the way from client->web api->console app, but I have trouble making it work. I can make the console app work as a server, but I can't figure out how to make the web api work as a client, so that when it spins up, creates a connection to the console app, and keeps it open for communication, while it delivers data to the clients upon requests.

I tried with different implementations and I have ended up with SignalR, as it seems like that's what people use today :)

Since I have all these problems getting a connection I am wondering if there are better ways of sending data that fulfills my requirements? If WebSocket (using SignalR) is the way to go, can you provide some links with working examples? I have tried all the top links from Google with no success ^^

Thanks in advance

Your WebAPI project can act as WebSocket server as well. Check this link that uses an IHttpHandler , but you can also do it in a WebAIP's controller how is explained here : Using WebSockets with ASP.NET Web API

The console application should connect as client, using for example ClientWebSocket class .

WebSockets are persistent full duplex connections, so once the client is connected both ends can push information to the other end.
