　　浏览器控制台

// 创建WebSocket连接
const ws = new WebSocket("ws://api.zhouein.com:8080/wss/");

// 连接成功回调
ws.onopen = () => {
  console.log("WebSocket连接已建立");
  // 连接成功后发送测试消息
  ws.send("Hello Server!");
};

// 接收消息回调
ws.onmessage = (e) => {
  console.log("收到消息:", e.data);
};

// 错误处理
ws.onerror = (error) => {
  console.error("WebSocket错误:", error);
};

// 关闭连接回调
ws.onclose = () => {
  console.log("WebSocket连接已关闭");
};

// 发送消息函数
function sendMessage(msg) {
  if (ws.readyState === WebSocket.OPEN) {
    ws.send(msg);
  } else {
    console.warn("连接未就绪，无法发送消息");
  }
}

// 关闭连接函数
function closeConnection() {
  ws.close();
