Detailed Description
Terms appearing in the embodiments of the present invention are explained below to assist understanding of the embodiments of the present invention.
Nodejs is a JavaScript runtime environment based on the Chrome V8 engine. Nodejs uses an event-driven, non-blocking I/O model. The V8 engine executes Javascript very fast and has very good performance. The Nodejs server refers to a server built based on Nodejs technology.
The OpenVPN is VPN software, which is realized by an application layer VPN based on an OpenSSL library, can run on Solaris, Linux, OpenBSD, FreeBSD, NetBSD, Mac OS X, Microsoft Windows, Android and iOS, and comprises a plurality of safety functions.
MQTT is a messaging protocol based on a publish/subscribe paradigm under the ISO standard (ISO/IEC PRF 20922). It works on the TCP/IP suite and is a publish/subscribe messaging protocol designed for remote devices with poor hardware performance and in poor network conditions.
Referring to fig. 1, a method for managing a device of the internet of things based on Nodejs is applied to a locally started Nodejs server, and a Nodejs server can be locally started through an RVPN (reverse VPN) management client between the implementation of the scheme by using the Nodejs server, and is not limited by a system environment and can operate under various systems.
The method comprises the following steps:
step 1, the Nodejs server receives an access instruction of the browser so as to return a user interface to the browser.
In the step, the user can access the Nodejs server based on the browser, and communication technologies including html, socket, router, comet, big pipe and restful can be applied when accessing.
And 2, the Nodejs server acquires the MQTT server address.
In this step, the address of the MQTT server may be stored in a local configuration file of the nodjs server, and the node js server reads the address from the configuration file, or the address may be sent by the browser.
And 3, the Nodejs server accesses the MQTT server address to acquire VPN configuration information.
Specifically, in some embodiments, the MQTT server is exclusive, and since there is no other user, the VPN group may not be distinguished, and the VPN configuration information is obtained by directly accessing the MQTT server address and performing certain permission check.
In another embodiment, the MQTT server manages multiple VPN groups, and at this time, the user is required to specify the VPN group through the browser, so that the nodjs server can obtain correct VPN configuration information from the MQTT server.
And 4, starting a VPN module by the Nodejs server, so that the VPN module is connected with the VPN server according to the VPN configuration information to obtain the state information of the equipment of the Internet of things.
The VPN module may be implemented by OpenVPN software, or the connection interface, the disconnection interface, and the monitoring state interface of the OpenVPN software are encapsulated in the VPN module to implement a function of connecting to a VPN server, where the VPN configuration information includes configuration information of a VPN group and OpenVPN configuration information. The OpenVPN configuration information is used for configuring parameters of an OpenVPN software related interface in the VPN module, and the configuration information of the VPN group is used for establishing a VPN channel between the Internet of things devices corresponding to the VPN group.
And step 5, the Nodejs server sends the state information of the equipment of the Internet of things to the browser so that the browser displays the state information of the equipment of the Internet of things.
After VPN connection is established, the Internet of things equipment sends state information to the Nodejs server through the VPN server, the Nodejs server sends the state information to the browser in a mode of carrying equipment identification, and the browser displays the state information of each Internet of things equipment at a corresponding position according to the equipment identification. The browser can display the state information in the form of characters, icons or patterns.
For the above embodiment, it is obvious that the interface can be reused in different systems, and the development time of the interface is reduced.
In some embodiments, the Nodejs server is configured with a row command parser and an interface for listening to row commands.
Specifically, the information in the nodjs server can be configured by a user in a line command mode by monitoring a local cmd program to obtain a cmd instruction and configuring and analyzing a program of a known instruction, so that an additional operation mode is added, and the user operation is more flexible.
In some embodiments, the method further comprises the steps of:
receiving a VPN group sent by the browser;
the accessing the MQTT server address to acquire VPN configuration information comprises the following steps:
and accessing the MQTT server address, and acquiring VPN configuration information according to the VPN group.
Specifically, in this step, the user may designate the VPN group through the browser, so that different groups are managed more conveniently, and the user managing different VPN groups may share the MQTT server, thereby optimizing resource configuration.
In some embodiments, the method further comprises the steps of:
and when the VPN information of the equipment of the Internet of things is changed, receiving new VPN configuration information sent by the MQTT server, and acquiring the state information of the equipment of the Internet of things according to the new VPN configuration information.
When the VPN information of the Internet of things equipment is changed, the Internet of things equipment can inform the Nodejs server that the VPN information of the Nodejs server is changed through the MQTT server, so that the Nodejs server can update the state of VPN configuration according to new VPN configuration information and reestablish a VPN channel with the Internet of things equipment.
In some embodiments, the obtaining of the state information of the internet of things device specifically includes:
and obtaining state information of different Internet of things equipment through different VPN channels.
Specifically, different devices are connected through different VPN channels, so that communication is independent, communication is timely and mutual interference is not easy to happen.
