Minimal java8 NiO secure websocket client (WSS)

It took me a long time to find a simple java websocket client that can use WSS without mess

I tried https://github.com/TooTallNate/Java-WebSocket

He added dependencies in descrirbes and copied sslclientexample Java to use websocket The org echo server is tested, but a compilation error is encountered on line 84. There is no such method setsocket()... (stuck here)

I tried Tyrus (it seems that this is a large library directly developed by Oracle), but it seems that I need to run some appserver (websocket container) to use it

I don't know. Is it so difficult for WebSockets that need to use netty or GlassFish or grizly?

I think we can use SSL engine (WSS) and pure Java SDK to implement one... What do I don't know about WebSockets? (I think it's very much like an ordinary socket)

Solution

NV websocket client is a new websocket client library written in Java It supports WSS and only needs JAVA se 1.5, so it can even run on Android

nv-websocket-client-1.3. Jar (released on May 6, 2015) has a size of 62854 bytes and does not require any external dependencies

The following is an example of "WSS"

import com.neovisionaries.ws.client.*;

public class HelloWSS
{
    public static void main(String[] args) throws Exception
    {
        // Connect to "wss://echo.websocket.org" and send "Hello." to it.
        // When a response from the WebSocket server is received,the
        // WebSocket connection is closed.
        new WebSocketFactory()
            .createSocket("wss://echo.websocket.org")
            .addListener(new WebSocketAdapter() {
                @Override
                public void onTextMessage(WebSocket ws,String message) {
                    // Received a response. Print the received message.
                    System.out.println(message);

                    // Close the WebSocket connection.
                    ws.disconnect();
                }
            })
            .connect()
            .sendText("Hello.");
    }
}
