网站欢迎页面怎么做推广手段和渠道有哪些

1.Netty服务端

服务端代码参考【基于Netty实现安全认证的WebSocket（wss）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");
