The time interval of the service node for acquiring the service content information and the node address from the Internet of things network is larger than the time interval of the service node for broadcasting the service content information and the node address to the Internet of things network.
Further, the node address is compared with the node address recorded in the service information dictionary, and when the node address which is not recorded in the service information dictionary is found (for example, when a new service node joins the internet of things network or the service node joins the internet of things network again), the new node address is used as a key, and the corresponding service content information is added into the service information dictionary as a value for storage.
Further, the node address and the key value pair corresponding to the service content information are added and updated in the service information dictionary, the update time of each key value pair is recorded at the same time, the internet of things node service management device checks the update time of each key value pair according to the set time interval, and when the update time is longer than the set time (longer than the time interval of broadcasting the service content information and the node address to the internet of things by the service node), the key value pair is deleted from the service information dictionary, so that the node address and the service content information which are recorded in the service information dictionary and are not acquired in the set time are deleted, and the service node corresponding to the node address recorded in the service information dictionary is ensured to be normally on line.
S203: and in response to the updating operation of the service information dictionary, updating the available service table based on the updated service information dictionary.
Specifically, the available service tables of the online-logged-in internet of things terminals are stored in the Redis database, after key value pairs in the service information dictionary are updated, the available service tables corresponding to the online-logged-in internet of things terminals are synchronously updated based on the updated service information dictionary in response to the updating operation of the service information dictionary. For example, determining node addresses recorded in each available service table, acquiring corresponding service content information from the updated service information dictionary, and performing overlay update. And when deleting the node address in the service information dictionary, synchronously deleting the node address and corresponding service content information in each available service list.
S204: and carrying out authority authentication on the Internet of things terminal based on authentication information uploaded by the Internet of things terminal to obtain an authority authentication result, wherein the authority authentication result records the node address of a service node of which the Internet of things terminal has service calling authority.
S205: and determining a node address corresponding to a service node of the Internet of things terminal with service calling authority, and determining the service content information corresponding to the node address according to the service information dictionary.
Specifically, service nodes with service calling authorities of the internet of things terminal are determined according to the authority authentication result, and node addresses corresponding to the service nodes are determined.
Further, according to the address correspondence between the service content information and the node address recorded in the service information dictionary, the service content information corresponding to the determined node address is called in the service information dictionary.
S206: and establishing an available service table for the terminal of the Internet of things according to the determined node address and the service content information.
Specifically, after determining the node address of the service node with the service call authority and the corresponding service content information of the internet of things terminal, an available service table is created for the internet of things terminal in a Redis database, and the determined node address and the determined service content information are recorded in the available service table.
S207: and responding to a service call request sent by the Internet of things terminal, and determining service content information indicated by the service call request.
In one possible embodiment, after the available service table corresponding to each internet of things terminal is created or updated, corresponding service content information is fed back to each internet of things terminal. The terminal of the Internet of things can determine the service capability which can be called to the Internet of things network according to the received service content information, and send a service calling request carrying the corresponding service content information to the node service management device of the Internet of things according to the service capability which needs to be called.
Specifically, after receiving a service call request sent by the internet of things terminal, the service call request is analyzed and service content information carried by the service call request is determined.
S208: and searching the determined service content information in the available service table, and determining a corresponding node address based on the searched service content information.
Specifically, an available service table corresponding to the internet of things terminal sending the service call request is called in the Redis database, and service content information carried by the service call request is searched and found in the available service table. If the service content information is found out, the service content information can be directly determined to be the service content information corresponding to the service call request, and if the service content information is found out, the service content information is randomly designated to be the service content information corresponding to the service call request.
Further, after searching and determining one piece of service content information, determining a node address corresponding to the service content information in the available service table, and determining a service node corresponding to the node address as a service node for providing corresponding service capability for the terminal of the internet of things.
