User Property

A username if authentication is to be used.

public function setUser($value);

Procedural Interface

ipworksmq_mqtt_get($res, 56 );

Default Value



This property can be set to a username if authentication is to be used.

In MQTT 3.1.1, while a User may be specified without a Password, setting a Password without a User is not supported; attempting to do so will cause the server to reject the connection attempt.

In MQTT 5, a Password may be set without a User, allowing the field to be used for credentials other than a password.

This property is not available at design time.
