服务端代码参考【基于Netty实现安全认证的WebSocketwss服务端-CSDN博客】
2.Netty客户端
客户端代码参考【基于Netty实现WebSocket客户端-CSDN博客】中两种都可以这里用的是第一种。
新增SslHandler的代码
SslContext sslCtx SslContextBuilder.forClient().trustManager(InsecureTrustManagerFactory.INSTANCE).build();
...
pipeline.addLast(sslCtx.newHandler(sc.alloc(), webSocketURL.getHost(), webSocketURL.getPort()));
服务端地址的协议头调整为wss
final URI webSocketURL new URI(wss://127.0.0.1:7070/helloWs);
