How can use netty websocket client with wss?

Now I need one websocket client, I find one websocket example (https://github.com/netty/netty/blob/master/example/src/main/java/io/netty/example/http/websocketx/client/WebSocketClient.java) in netty , but it only support ws. Who could provide one websocket client example which support wss?

Who can help me ?

Thanks

I put the SslHandler as the first hander in the ChannelPipeline now

 SSLEngine sslEngine = SSLContextProvider.get().createSSLEngine();
 sslEngine.setUseClientMode(true);
 pipeline.addLast("ssl", new SslHandler(sslEngine));

Then run the WebSocketClient in example to connect one websocket server with wss, get one error:

WebSocket Client sending message
java.lang.ClassCastException: io.netty.handler.codec.http.websocketx.TextWebSocketFrame cannot be cast to io.netty.buffer.ByteBuf
    at io.netty.handler.ssl.SslHandler.write(SslHandler.java:389)

How to fix it?

回答1:

Just put the SslHandler as the first hander in the ChannelPipeline. That's all.

回答2:

Just follow the netty websocket client example in Github Netty client example with WSS/WS

Just change the URL from ws to wss
