Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and do not limit the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
In the prior art, when the internet of things device and the cloud server communicate based on the internet of things, a long connection between the internet of things device and the long connection server at the cloud end needs to be established first, and the corresponding relationship between the internet of things device and the long connection server is recorded in the long connection server, so that the long connection server can continue to perform message communication with the internet of things device through the long connection. The long connection is used without frequent connection establishment and disconnection, so that the performance consumption is avoided, and the communication between the Internet of things equipment and the long connection server is optimized.
When a scene that a long connection server actively sends a message to be pushed to the Internet of things equipment is not involved, the long connection can be freely expanded and reduced; however, as the number of the internet of things devices increases, a plurality of long connection servers are correspondingly required to be deployed at the cloud for connection and communication with the plurality of internet of things devices, and at this time, a cache (for example, Redis) is required to record the corresponding relationship between the internet of things devices and the long connection servers. In the prior art, a traditional solution for sending a message to be pushed to an internet of things device by a management backend at the cloud is shown in fig. 1, after the internet of things device and a long connection server are connected through a load balancing device, a cache is needed to record a corresponding relation between the internet of things device and the long connection server, and the corresponding relation between the internet of things device and the long connection server in the cache is deleted when the long connection is disconnected. Although the prior art can realize message communication between the internet of things equipment and the management background of the cloud, the prior art has the following defects that the message pushing process depends heavily on the corresponding relation between the internet of things equipment and the long connection server recorded in the cache, the requirements on the stability and the performance of the cache are high, and when a problem occurs in the cache, the pushing function of the long connection server is completely disabled; after the cache is recovered from the abnormal state, the corresponding relation between the internet of things equipment and the long connection server does not exist in the cache, if the server needs to actively send a message to the internet of things equipment, the message can be continuously pushed to the internet of things equipment from the management background of the cloud end after the cache records the corresponding relation between the internet of things equipment and the long connection server again, and the message pushing efficiency is seriously influenced.
The embodiment of the invention provides a message pushing method, which is applied to a long connection server of the Internet of things as shown in FIG. 2, and specifically comprises the following steps:
step S101: periodically acquiring a message to be pushed from a preset storage space of the Internet of things according to a set time interval; and the message to be pushed is stored in the preset storage space by a management background of the Internet of things through a management background server.
The message to be pushed comprises the identification information of the target Internet of things equipment corresponding to the message.
Specifically, the preset storage space is a message middleware, the management background of the internet of things is used as a Producer (Producer) of the message middleware, the long connection server is used as a Consumer (Consumer) of the message middleware, the message to be pushed, which is generated by the management background of the internet of things and is forwarded by the management background server and is pushed to the target internet of things device, exists in a Key-Value form, the Key is the identification information of the internet of things device corresponding to the message to be pushed, and the Value is the content of the message to be pushed. As shown in fig. 3, when the management backend of the internet of things produces a message to be pushed, the management backend server needs to forward the message to be pushed to the message middleware in advance for storage, so that the long connection server acquires the message to be pushed from the message middleware according to the preset time.
Specifically, the message middleware is one of RockettMQ, ActiveMQ, RabbitMQ and Kafka. Preferably, the message middleware is Kafka.
In this embodiment, a manner of additionally adding the corresponding relationship between the internet of things device and the long connection server to the cache in the prior art is abandoned, and only the corresponding relationship between the internet of things device and the long connection server needs to be recorded in the long connection server, and the message to be pushed is stored by means of the message middleware, so that the long connection server can acquire the message to be pushed, which meets the pushing requirement, from the message middleware, and actively send the message to be pushed to the internet of things device through long connection. Therefore, the message pushing process between the management background of the cloud and the Internet of things equipment does not need to depend on the corresponding relation between the Internet of things equipment and the long connection server recorded in the cache, and the problem that the pushing function of the long connection server is completely broken down when the cache fails is solved fundamentally. In addition, if the cache recovers from the abnormality, the corresponding relationship between the internet of things device and the long connection server does not exist in the cache, if the management background at the cloud generates a push message to be sent to the internet of things device, the cache needs to wait for recording the corresponding relationship between the internet of things device and the long connection server again, and then the message can be continuously pushed to the internet of things device from the management background at the cloud. The message middleware has higher availability and stability than the cache. Meanwhile, the message middleware has the characteristic of peak clipping and valley filling, so that scenes of a large number of instant messages to be pushed can be easily coped with. When the push efficiency needs to be improved, linear improvement of the push efficiency can be quickly and conveniently realized by increasing the number of fragments of the message queue and the number of long connection servers in the message middleware.
Further, before the message to be pushed is periodically acquired from the preset storage space of the internet of things according to the set time interval, the method further includes:
step A1: receiving a connection establishment request which is sent by the equipment of the Internet of things to be established and forwarded by the load balancing equipment;
the load balancing equipment is equipment which uniformly disperses a connection request sent by the equipment of the Internet of things to be connected to the long connection server with the residual resources by adopting a balanced distribution algorithm, and the load balancing equipment enables the connection request to obtain the response of the long connection server connected with the load balancing equipment as fast as possible by managing the received connection request and the long connection server, so that the reasonable distribution of the long connection server is realized.
Step A2: analyzing the identity identification information of the Internet of things equipment to be built from the building request;
the identity identification information of the to-be-built Internet of things equipment is the unique identification of the to-be-built Internet of things equipment.
Step A3: and establishing long connection between the long connection server and the equipment of the Internet of things to be established based on the analyzed identity identification information.
The long connection means that a plurality of messages to be pushed can be continuously sent on one transmission connection, and if no message to be pushed is sent during the long connection holding period, a heartbeat packet needs to be sent regularly to ensure the availability of the long connection.
Further, after the long connection is established between the long connection server and the to-be-established internet of things device based on the analyzed identification information, the method further includes:
the method comprises the steps of obtaining a socket of the established long connection, storing the identification information of the to-be-established Internet of things equipment and the socket into an identification information table corresponding to the long connection server, and establishing the association relationship between the identification information of the to-be-established Internet of things equipment and the socket in the identification information table.
The socket of the long connection is a socket interface which is established on a transmission protocol and used for supporting establishment of a bidirectional communication channel between the long connection server and the Internet of things equipment, and the socket is composed of identification information of the Internet of things equipment to be established, the transmission protocol (such as a TCP protocol) and IP address information of the long connection server.
Specifically, different long connection servers correspond to different identity information tables, and the identity information tables are used for storing identity identification information of each piece of internet-of-things equipment connected with the long connection servers and socket sockets of long connections established between the long connection servers and the pieces of internet-of-things equipment.
In the embodiment, because a large number of long connections established between the internet of things equipment and the long connection server exist in the communication process, in order to distinguish different long connections, a corresponding socket is set for the long connection established between each long connection server and the internet of things equipment to be established, so as to distinguish different long connections established between the same long connection server and a plurality of internet of things devices, the long connection server can distinguish the messages to be pushed, which are stored in the message middleware and need to be pushed to different internet of things devices, through the socket, so that the accurate pushing of the messages to be pushed is realized, the management background server is not required to obtain the long connection server connected with the internet of things devices corresponding to the messages to be pushed from the cache, and the logic of pushing the messages to be pushed to the internet of things devices by the management background at the cloud end is simplified.
Step S102: and analyzing the identity identification information of the target Internet of things equipment from the message to be pushed, and judging whether the identity identification information of the target Internet of things equipment exists in the identity identification information of all the Internet of things equipment which establishes long connection with the long connection server.
Specifically, the determining whether the identification information of the target internet of things device exists in the identification information of all the internet of things devices that establish long connection with the long connection server includes the following steps:
and judging whether the identity information of the target Internet of things equipment exists in the identity information table.
The socket communication with the target Internet of things equipment can be obtained by only obtaining the identification information of the target Internet of things equipment and searching the socket of the long connection having the association relation with the identification information from the identification information table.
Step S103: if the identity identification information of the target Internet of things equipment exists in the identity identification information of all the Internet of things equipment which establishes long connection with the long connection server, the message to be pushed is sent to the target Internet of things equipment through long connection; and if the identity identification information of the target Internet of things equipment does not exist in the identity identification information of all the Internet of things equipment which establishes long connection with the long connection server, ignoring the message to be pushed.
In this embodiment, since the messages to be pushed stored in the message middleware all carry the identification information of the corresponding target internet of things device, the long connection server only needs to acquire the messages to be pushed from the message middleware at preset time intervals, and judge whether the target internet of things device corresponding to the identification information carried in the messages to be pushed is the internet of things device which establishes the long connection with the long connection itself, and if so, send the messages to be pushed to the target internet of things device through the long connection. According to the message pushing method provided by the embodiment, the management background server corresponding to the management background of the Internet of things does not need to acquire the long connection server corresponding to the message to be pushed from the cache, and does not need to acquire the corresponding relation between the long connection server and the Internet of things equipment connected with the long connection server, and only the management background server needs to send the message to be pushed to the message middleware, so that the pushing logic of the management background of the cloud is optimized, the dependence of the pushed message on the cache is also stripped, and the pushing efficiency is improved.
Further, the sending the message to be pushed to the target internet of things device through a long connection specifically includes:
step B1: acquiring a target socket which has an incidence relation with the identity identification information of the target Internet of things equipment from the identity information table;
step B2: and sending the message to be pushed to the target Internet of things equipment through long connection corresponding to the target socket.
In the embodiment, a message to be pushed, which is produced by a management background of the internet of things and is pushed to target internet of things equipment, is stored by using a message middleware, the message to be pushed is periodically pulled from the message middleware by a long connection server, and the message to be pushed is pushed to the target internet of things equipment which establishes long connection with the message to be pushed, so that message communication between the management background of the cloud and the internet of things equipment is realized; because the corresponding relation between the Internet of things equipment and the long connection server is not required to be recorded by using a cache, the dependence of the message pushing process on the cache in the prior art is avoided, the condition that the corresponding relation between the Internet of things equipment and the long connection server is required to be cached again due to the abnormal cache is not required to be worried about, and the cache is not required to be updated when the corresponding relation between the Internet of things equipment and the long connection server is replaced, so that the framework of message pushing is simpler; in addition, when the management background of the cloud end pushes the information to the internet of things equipment, the management background server does not need to acquire the long connection server corresponding to the internet of things equipment from the cache, so that the information to be pushed does not need to be sent to the long connection server, and the pushing logic of the management background of the cloud end and the management background server is simplified; meanwhile, the message middleware has the function of peak clipping and valley filling, so that the message to be pushed is stored through the message middleware, the scene that a management background server instantly sends a large number of messages to be pushed can be easily coped with, and the operating pressure of the equipment of the Internet of things and the long connection server is relieved; and because the corresponding relation between the Internet of things equipment and the long connection server is stored in the long connection server, even if the message middleware is abnormal, the corresponding relation between the Internet of things equipment and the long connection server is not influenced, so that the message middleware is used for replacing cache, and the safety and reliability of message communication between the Internet of things equipment and the cloud can be enhanced, therefore, the message middleware has higher usability and stability relative to the cache, and the message pushing efficiency is improved.
