WSS协议示例 AIWROK 版websocket

WSS协议示例 AIWROK 版websocket B2B网络软件

/**
* WSS 协议示例 - AIWROK 版
*
* 使用 AIWROK 原生 websocket 对象实现 ws:// 和 wss://（TLS 加密）连接
* 支持：双向通信、心跳保活、断线重连、JSON 消息收发
*
* AIWROK 原生 WebSocket API：
* new websocket() - 创建实例
* ws.setSocketID(String) - 设置唯一ID
* ws.event(onOpen, onMsg, onErr, onClose) - 挂载四个回调
* ws.connet(String) - 连接服务器（注意是双n）
* ws.send(String) - 发送消息
* ws.close() - 关闭连接
*
* ws:// 和 wss:// 的区别：
* wss:// 走 TLS 加密通道，数据传输安全
* AIWROK 的 websocket 对象会自动处理 TLS 握手
*
* 依赖：AIWROK 原生 websocket 对象，零依赖
*
* 使用方法：
* 1. 修改 CFG.serverUrl 为你的 wss:// 地址
* 2. AIWROK 中直接运行本脚本
* 3. 日志窗口查看连接状态和收发消息
