System net websockets client example

  • The ConnectAsync method initiates the WebSocket handshake with a remote network destination, and then negotiates the sub-protocol. For plain WebSocket connections, use the ws:// scheme in the uri. For secure WebSocket connections over TLS/SSL, use the wss:// scheme. This operation will not block.
To use the HTTP server and client one must require('http'). The HTTP interfaces in Node.js are designed to support many features of the protocol which have been traditionally difficult to use. In particular, large, possibly chunk-encoded, messages.

    It is expected that many websocket clients and servers will exchange data in JSON format. For Go programs this means that a Go object will be marshalled into JSON format as described in Chapter 4: Serialisation and then sent as a UTF-8 string, while the receiver will read this string and unmarshal it back into a Go object.

    Because Node networking is event-driven, clients “run in a loop” by default—so to make it a use-once client, the client would have to explicitly call client.destroy() or submit data with client.end(), or we can let the server do the close. (Note how this differs from the Java and Python servers we saw earlier, where use-once was the ...
