Description
Technical Field
The invention relates to the technical field of Internet, in particular to a terminal control method of a self-adaptive network based on CGI.
Background
MQTT (Message Queuing Telemetry Transport, message queue telemetry transport) is a lightweight instant messaging protocol developed by IBM corporation. The MQTT adopts a publish/subscribe mode rather than a traditional request/response mode, and this lighter-weight mode makes the MQTT more suitable for low-power and network bandwidth-limited internet of things devices. As an instant messaging protocol with low cost and low bandwidth occupation, the method has wider application in the aspects of Internet of things, small-sized equipment, mobile application and the like.
CGI: the universal gateway interface (Common Gateway Interface) is a standard interface for Web server hosts to provide information services. Through the CGI interface, the Web server can acquire information submitted by the client, transfer the information to a CGI program of the server for processing, and finally return a result to the client.
Along with the development of information technology in recent years, the influence of intelligent control on the life style of people is larger and larger, intelligent terminal equipment is in the face of new development opportunities, and meanwhile, new challenges are faced, and how to realize flexible control of terminal equipment in different network environments, adapt to various network environments and improve control efficiency is one of the focuses of attention.
Most of the existing terminal remote control methods need to redefine a new control interface according to the requirement of an access platform, the original CGI interface of the terminal cannot be directly reused, and a large amount of development work is needed according to a platform interface protocol when the terminal is accessed;
the existing control method only carries out remote control through the Internet singly, can not control when equipment is not connected with the Internet (assembly and maintenance or network abnormality), simultaneously carries out remote control through the Internet singly, has the problems of delay, poor stability and the like when the network is poor, and besides, also faces the problem of high concurrency processing when a platform is connected with mass equipment.
Disclosure of Invention
In order to solve the problems in the prior art, the invention aims to provide a terminal control method of a self-adaptive network based on CGI, and the invention improves the control efficiency of a terminal.
In order to achieve the above purpose, the invention adopts the following technical scheme: the terminal control method of the self-adaptive network based on the CGI comprises a front-end page, an MQTT server, a terminal plug-in and a terminal CGI interface, and the terminal control method comprises the following steps:
starting a network detection process in the background after the front-end page is started, automatically attempting to connect the terminal equipment through the local area network, if the connection is possible, keeping heartbeat detection with the terminal equipment, marking the network state as the local area network, and immediately marking the network state as the Internet once the heartbeat detection is not passed;
when the network state is marked as a local area network, the front-end page directly calls a terminal CGI interface of the terminal equipment through a terminal equipment local area network address to complete the control of the terminal equipment, when the network state is marked as the Internet, the front-end page directly uploads terminal CGI interface instruction data to the MQTT server, the MQTT server forwards the terminal CGI interface instruction data through a specified theme, and the terminal plug-in receives the terminal CGI interface instruction data through subscribing the specified theme and transmits the terminal CGI interface instruction data to a terminal CGI module to process corresponding instruction data and acquire an execution result;
and then the terminal plug-in unit returns the unique control instruction code and the instruction execution result to the MQTT server, and the MQTT server identifies the returned result according to the unique control instruction code and forwards the result to the front-end page, so that the terminal remote control under the Internet state is completed.
The beneficial effects of the invention are as follows:
the invention performs scheduling based on the original CGI interface of the terminal to control the terminal, and solves the problems of development workload increase and low access efficiency caused by the fact that the original CGI interface of the terminal cannot be reused and the terminal is required to perform interface development to meet the access requirement of a platform. Meanwhile, the invention can control the terminal under both the Internet environment and the local area network environment, automatically detects, identifies and preferentially selects the network self-adaptive mode of the local area network, directly calls the terminal CGI through the local area network to control the equipment, and solves the problem that the equipment cannot be controlled when the equipment is not connected with the Internet (the installation and maintenance or the network is abnormal); the self-adaptive mechanism of network automatic detection and identification is used for preferentially selecting the local area network for equipment control, so that the problems of delay, poor stability and the like when the network is poor are solved by singly performing remote control through the Internet, and meanwhile, the control signals are not forwarded through the central server in a centralized way, so that the concurrent processing problem when the platform is accessed to mass equipment is solved.
Drawings
FIG. 1 is a flow chart of an embodiment of the present invention.
Detailed Description
Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Examples
As shown in FIG. 1, the terminal control method of the self-adaptive network based on the CGI mainly depends on the combination of a front-end page, an MQTT server, a terminal plug-in unit and a terminal CGI interface. The front-end page starts a network detection process in the background after being started, automatically tries to connect the equipment through the local area network, keeps heartbeat detection with the equipment if the equipment can be connected, marks the network state as the local area network, and immediately marks the network state as the Internet once the heartbeat detection is not passed. When the network state is marked as a local area network, the front-end page directly calls a CGI (common gateway interface) of the equipment through the address of the local area network of the equipment to complete the control of the equipment, when the network state is marked as the Internet, the page directly uploads the CGI instruction data to the MQTT server, the MQTT server forwards the CGI instruction data through a specified theme, and the terminal plug-in receives the interface instruction data through subscribing the specified theme and transmits the interface instruction data to the terminal CGI module to process the corresponding instruction data and acquire an execution result. And then the terminal plug-in unit returns the unique control instruction code and the instruction execution result to the MQTT server, and the MQTT server identifies the returned result according to the unique control instruction code and forwards the result to the front-end page, so that the terminal remote control under the Internet state is completed.
Wherein, the control instruction protocol is defined as follows:
the control instruction execution result return protocol is defined as follows:
the foregoing examples merely illustrate specific embodiments of the invention, which are described in greater detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
