Question

我正在使用此网络套接字库

并设置此代码以测试我的websocket连接是否仍然打开

const interval = setInterval(function ping() {
  wss.clients.forEach(function each(ws) {
    if (ws.isAlive === false) {
      console.log("I am terminating");
      let obj = self.system._getClientByWs(ws)
      let tenant = obj.tenant
      self.system.deleteClient(obj, tenant)
      return ws.terminate();
    }
    ws.isAlive = false;
    console.log("Sending Ping");
    ws.ping(self.noop);
  });
}, 30000);

我在遇到错误

ws.ping(self.noop)

个

我目前在网上找不到太多原因，提出的唯一解决方案是添加错误处理，但这不是在ping方法上，而是在wss.on（'connection'）方法上

任何帮助将不胜感激！
