The MQTT client refers to the protocol component used in the doctor-patient instant communication application, which is responsible for connecting to the MQTT server and exchanging information. In the doctor-patient instant communication application, both the patient side and the doctor side need to initialize the MQTT client when the application starts, and use mqtt.connect to establish a connection with the MQTT server. Authentication refers to the MQTT server authenticating through the username and login password provided by the MQTT client. The username and login password are the information set by the user when registering an account in the doctor-patient instant communication application. Verification parameters Refers to the parameter generated after the MQTT server verifies the username and login password. This parameter has four representation forms, namely "wrong username", "wrong login password", "both username and login password are wrong", and "successful login". "Wrong username" means that the username entered when logging into the doctor-patient instant messaging application is different from the username recorded in the MQTT server. "Wrong login password" means that the login password entered when logging into the doctor-patient instant messaging application is different from the login password recorded in the MQTT server. "Both username and login password are wrong" means that the username and login password entered when logging into the doctor-patient instant messaging application are different from the username and login password recorded in the MQTT server. "Successful login" means that the username and login password entered when logging into the doctor-patient instant messaging application are the same as the username and login password recorded in the MQTT server, and the doctor-patient instant messaging application is successfully logged in.
