Javascript 如何在mqtt中传递用户名和密码等连接选项

我在修复mqttprops时收到

失败：WebSocket握手期间出错：net:：ERR\u CONNECTION\u RESET

此错误

我试着用这些道具

mqttProps: {
      host: "157.245.85.49:8084/mqtt",
      username: "tolomoto",
      password: "S36EeqD956UwGCYC",
    },

或

或

mqttProps:“ws://157.245.85.49:8084/mqtt”

或

mqttProps:“ws://tolomoto:S36EeqD956UwGCYC@157.245.85.49：8084/mqtt

---

请告诉我如何解决此问题。

您使用哪个js库连接mqtt broker？

mqttProps: {
     protocol: "wss",
       host: "wss://157.245.85.49:8084/mqtt",
      port: "8084",
       username: "tolomoto",
       password: "S36EeqD956UwGCYC",
     },
