Question

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

Jose


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?

No correct solution

OTHER TIPS

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

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

Just change the URL from ws to wss
