HTML5 Socket.IO是否在C ++中可用？

Question

I have a server that creates a websocket . I'm using HTML5 , Javascript and JQuery on the client side.

My fellow-student who works on the project uses RFID technology to scan a tag. Then he needs to send me those data from his app via the socket.

Is that possible with his preferred language C++ ? And how does he need to do that?

Answer 1

There are some websocket implementations for C++ available. See http://en.wikipedia.org/wiki/Comparison_of_WebSocket_implementations Unfortunately I don't have experience with any of them.

When none of these libraries works out for you, I would not recommend that you create your own implementation of WebSocket. It's not a very simple protocol (I know what I am talking about - I wrote a websocket server in Java) and it only makes sense when the client is a web browser. When the client is able to use pure TCP/IP sockets, like a client written in C++, there is no reason to add WebSocket as another layer of indirection.

So you should rather implement an alternative network handler on your server which listens to a normal non-web socket. That would be a lot easier and also reduce protocol overhead and CPU load on client and server.
