Before explaining the present invention in detail, a brief description will be given of a business processing system according to the present invention. The service processing system comprises a service initiator and at least two service processing nodes. Data flow exists between the service initiator and the at least two service processing nodes, is used for issuing service processing instructions to the at least two service processing nodes, and can be a terminal device such as a mobile phone, a tablet computer, a desktop computer and the like. The service initiator may set one service issuing port, and issue the service to be executed to the at least two service processing nodes based on the service issuing port, for example, may issue a print takeout order or other service to the at least two service processing nodes. The at least two service processing nodes are a plurality of working terminal devices arranged in a store, such as printers, air conditioners, televisions and the like, receive a service processing instruction issued by a service initiator, and determine whether to accept processing of the service processing instruction by judging whether the service processing node has a function of processing the service instruction, so that a central server for distributing tasks is prevented from being arranged in the whole service processing system. The service initiator and at least two service processing nodes may establish a Transport layer Protocol based on a User Datagram Protocol (UDP) Protocol, or may also implement data flow by using link layer broadcasts such as MQTT (Message queue Telemetry Transport) broadcast, bluetooth broadcast, ICMP (Internet Control Message Protocol) broadcast, and the like.
An embodiment of the present invention provides a service processing method, as shown in fig. 2A, the method includes:
201. the service initiating direction broadcasts a service processing instruction to at least two service processing nodes.
The inventor realizes that in order to make a store more intelligent, the labor in the store is liberated, and the operation cost of the whole store is reduced, at present, many services in the store are executed by different terminal devices, for example, a POS machine executes an order placing service, a number calling machine executes a number calling service, a cooking machine executes a dish making service, and the like. Because the terminal devices need to be managed uniformly, a store usually needs to rely on a service processing platform, and the service descriptions of the terminal devices are all handed to the service processing platform, so that the terminal devices are all accessed into the service processing platform, and the terminal devices are managed uniformly in the service processing platform. Generally, a service processing platform operates on a central server, that is, a plurality of terminal devices give service descriptions to the central server, and the central server performs service maintenance and management. However, the centralized management mode using the service processing platform has a certain disadvantage that once the service processing platform fails, the terminal devices in the whole store cannot perform service processing normally, and the store is in a paralyzed state. Therefore, the invention provides a service processing method, which does not need to set a service processing platform, all terminal devices are used as service processing nodes, a service processing system is further formed based on the service processing nodes, a service initiator directly issues services to be processed to the service processing system, each service processing node automatically judges whether the service can be processed or not, requests the service initiator for processing when the service can be processed, and the service initiator selects which service processing node to process the service.
A plurality of terminal devices are usually installed in a store, and thus, the plurality of terminal devices can serve as at least two service processing nodes. In order to enable a service initiator to have information communication with at least two service processing nodes, the service initiator can issue a service processing instruction to the at least two service processing nodes, a service issuing port can be set in a service processing system, the service initiator provides a corresponding service for the service issuing port, and the at least two service processing nodes monitor the service issuing port, so that the service issuing port broadcasts the service processing instruction to the at least two service processing nodes in a broadcasting manner, and each service processing node can be ensured to acquire the issued service.
For example, the printer can only process a task of a print request class and cannot process a task of an instruction forwarding class or an abnormal class, so that when a service initiator issues a corresponding service to a service issue port, the service initiator needs to provide a service type to be processed and service data to be processed, so that a subsequent service processing node can determine whether the subsequent service processing node can process the service based on the service type to be processed. Specifically, the types of the to-be-processed services may be as shown in fig. 2B, and include a request type, a callback type, a forwarding type, an exception type, and a confirmation type, so that the corresponding to-be-processed service data may be a request serial number, a signature, a request timestamp, and the like.
When the whole service processing system operates, firstly, the network of the service processing system needs to be initialized, and a unique network identifier for proving the identity of all service processing nodes in the service processing system is allocated, so that when a subsequent service processing node requests to process a certain service, the subsequent service processing node requests a service initiator based on the network identifier of the subsequent service processing node, and the service initiator determines the identity of the corresponding service processing node.
In the process of practical application, when a service initiator acquires a service type to be processed and service data to be processed, in order to ensure the security of the service type to be processed and the service data to be processed in the process of transmitting the service type to be processed and the service data to be processed to service processing nodes and avoid the service type to be processed and the service data to be processed from being tampered, a pair of public and private keys can be set for the service initiator in a service processing system, the public keys are provided for each service processing node, and the private keys are stored by the service initiator. When the type of the service to be processed and the service data to be processed need to be transmitted, the characteristic that a public and private key pair can be used for mutual encryption and decryption is utilized, the service initiator encrypts the type of the service to be processed and the service data to be processed by adopting a private key to generate a service processing instruction, and broadcasts the service instruction to at least two service processing nodes in a service processing system, so that each service processing node can decrypt the service processing instruction based on the public key, and the type of the service to be processed and the service data to be processed are obtained. In the process of practical application, a uniform key can be set for encryption or the type of the service to be processed and the service data to be processed are directly packed as a service processing instruction, and the like.
202. The service processing node monitors the service initiator to obtain a service processing instruction broadcasted by the service initiator.
In the embodiment of the invention, because the service initiator issues the tasks to be processed to the service processing nodes in the service processing system based on the service issuing port, each service processing node in the service processing system monitors the service issuing port in real time, thereby acquiring the service processing instruction broadcasted in the service processing system from the service initiator.
Considering that the whole service processing system includes at least two service processing nodes, in order to distinguish the service processing nodes, before the service processing system starts to operate normally, the service processing system allocates network identifiers to the at least two service processing nodes, that is, names the at least two service processing nodes, so as to ensure that when a service processing request is received subsequently, which service processing node specifically wants to process a service can be distinguished according to the network identifiers. Therefore, before monitoring a service initiator, a service processing node needs to initialize network configuration, receive a network identifier distributed by a service processing system, and identify the distributed network identifier as a local network identifier of the service processing node on the service processing node, so that a subsequent service processing system can identify the service processing node on the basis of the network identifier.
The service processing instruction may be obtained by encrypting the service type to be processed and the service data to be processed by the service initiator, and the public key of the service initiator is disclosed to each service processing node, so that after the service processing node obtains the service processing instruction, the public key of the service initiator can be obtained, and the public key is used for decrypting the service processing instruction, so as to obtain the service type to be processed and the service data to be processed.
It should be noted that, in the embodiment of the present invention, any node in the service processing system is taken as an example for description, and each service processing node in the service processing system performs work by using the service processing flow in the embodiment.
203. And when the type of the service to be processed is consistent with the type of the service to be processed, the service processing node sends a service processing request carrying the target network identifier to the service initiator.
In the embodiment of the present invention, since different service processing nodes have different functions and services that can be completed, and the processable service type is a service type that the service processing node supports processing, each service processing node has a processable service type corresponding to its own function attribute, that is, the service processing node can only process service data whose service type to be processed is consistent with the processable service type. Therefore, after the service processing node extracts the service type to be processed and the service data to be processed in the service processing instruction, the service type to be processed needs to be compared with the processable service type of the service processing node, and only when the service type to be processed is consistent with the processable service type, the subsequent processes of preparation processing, request processing and the like are continuously executed. When the type of the service to be processed is not consistent with the type of the service to be processed, it indicates that the service processing node does not have the capability of processing the service, and therefore, the service processing node ignores the service processing instruction obtained at the service initiator.
When the service processing node determines that the type of the service to be processed is consistent with the type of the service to be processed, it indicates that the service processing node can process the service processing instruction received at the service initiator at this time, and therefore, in order to indicate to the service initiator that the service processing node itself wants to process the service, the service processing node generates a service processing request carrying a target network identifier for indicating its identity, and returns the service processing request to the service initiator, so that when the service initiator receives the service processing request, it can determine which service processing node wants to process the service according to the service processing request.
In the process of practical application, it is likely that a service processing node is processing a certain service at this time, and is not in an idle state at present, and cannot immediately process the service at this time, so that, in order to prevent the service processing node from requesting a processing task in the non-idle state, which causes the processing of the task to be delayed and affects the progress, when the type of the service to be processed is consistent with the type of the processable service, the service processing node may first cache the data of the service to be processed, and query whether the service being processed exists in its own processing queue. If the service being processed exists in the processing queue, the service processing node is not idle at the moment and cannot immediately request the service initiator to process the service of the current time, so that the service processing node continues to process the service being processed and sends a service processing request carrying the target network identifier to the service initiator when the service being processed is finished. If there is no service being processed in the processing queue, it indicates that the service processing node is in an idle state at this time, and it can now want the service initiator to request to process the task, so the service processing node can immediately send a service processing request to the service initiator.
204. When a service initiator receives a service processing request returned by at least one service processing node, a target service processing request is determined, a target network identifier is extracted from the target service processing request, a confirmation broadcast carrying the target network identifier is generated, and the confirmation broadcast is broadcast to at least two service processing nodes.
In the embodiment of the present invention, each service processing node receives a service processing instruction broadcasted by a service initiator, and each service processing node determines whether it can process the service according to the type of the service to be processed, and no at least one service processing node in the service processing system can process the service of this time, so that the service initiator can receive a service processing request returned by at least one service processing node, and thus, the service initiator needs to select one service processing node from the at least one service processing node to process the service of this time.
When selecting which service processing node to process the current service, the service processing node can be determined according to the receiving time of the received service processing request, and the service processing request received first is selected as the target service processing request, so that the service processing node which sends the target service processing request is subsequently used as the service processing node which processes the current service. Specifically, when receiving a service processing request returned by at least one service processing node, a service initiator first determines the receiving time of each service processing request; and then, the service initiator sequences the service processing requests returned by at least one service processing node according to the sequence of the receiving time from small to large, and takes the service processing request ranked at the head as a target service processing request.
After the target service processing request is determined, each service processing node carries its own network identifier in the service processing request when returning the service processing request, so that the service initiator can extract the target network identifier from the target service processing request and determine the service processing node corresponding to the target network identifier to process the task.
In order to enable all service processing nodes in the service processing system to know that the current service has been selected to be processed by the corresponding service processing node, the service initiator generates a confirmation broadcast carrying a target network identifier, and broadcasts the confirmation broadcast to at least two service processing nodes in the service processing system, so that the service processing node corresponding to the target network identifier can know that the service processing node is selected to process the current service and start service processing, and further, other service processing nodes in the service processing system can be informed that the current service is allocated without continuously waiting for the current service.
205. The service processing node receives the confirmation broadcast of the service initiator broadcast, and if the confirmation broadcast carries the target network identifier, the service processing node executes the following steps 206 to 208; if it is determined that the broadcast does not carry the target network identifier, the service processing node performs the following step 209.
In the embodiment of the invention, when the service processing node receives the confirmation broadcast broadcasted by the service initiator, the confirmation broadcast carries the network identifier for indicating the service node for processing the service, so that the service processing node can determine whether to select the service to process the service by inquiring whether the confirmation broadcast carries the target network identifier of the service processing node. Specifically, if it is determined that the broadcast carries the target network identifier, it indicates that the service is processed by the service processing node, and the service processing node may continue to execute the service processing process, that is, execute the following steps 206 to 208. If it is determined that the broadcast does not carry the target network identifier, it indicates that the service is not processed by the service processing node, and the service processing node needs to continue to receive other types of services to be processed and other data of services to be processed, which are broadcast by the service initiator, that is, the following step 209 is executed.
206. And if the broadcast is confirmed to carry the target network identifier, the service processing node processes the service data to be processed.
In the embodiment of the invention, if the broadcast is confirmed to carry the target network identifier, the service is processed by the service processing node, and the service processing node can continue to execute the service processing process, so that the service processing node processes the service data to be processed. For example, assuming that the service processing node is a printer, the service processing node may print out the service data to be processed.
207. And when the to-be-processed service data is processed, the service processing node generates a service processing result and returns the service processing result to the service initiator.
In the embodiment of the invention, when the service data to be processed is processed, in order to inform the service initiator that the service is processed, the service processing node generates a service processing result and returns the service processing result to the service initiator. It should be noted that, considering that a service initiator may issue multiple service types to be processed and service data to be processed at the same time, in order to enable the service initiator to determine which service has been processed, when a service processing node generates a service processing result, the service processing result may carry the service types to be processed and the service data to be processed. The embodiment of the invention does not specifically limit the content carried in the service processing result.
208. And the service initiator receives the service processing result returned by the service processing node indicated by the target network identifier and displays the service processing result.
In the embodiment of the invention, when the service initiator receives the service processing result returned by the service processing node indicated by the target network identifier, the service processing node can be determined to have completed the service processing process, and at the moment, the service processing result is displayed so as to inform the user that the service processing is completed.
209. If the broadcast is confirmed not to carry the target network identification, the service processing node clears the cached service data to be processed and continues to monitor the service initiator.
In the embodiment of the present invention, if it is determined that the broadcast does not carry the target network identifier, it indicates that the service is not processed by the service processing node, and if the service processing node caches the to-be-processed service data, the cached to-be-processed service data may be cleaned, and other to-be-processed service types and other to-be-processed service data broadcast by the service initiator may be continuously monitored, and the process shown in step 202 may be repeatedly executed.

The service initiator receives a service processing request returned by at least one service processing node, determines the service processing node sending the target service processing request from the at least one service processing node, generates a confirmation broadcast carrying a target network identifier of the service processing node, and broadcasts the confirmation broadcast to all the service processing nodes, so that the service processing node corresponding to the target network identifier can start to process the service after receiving the confirmation broadcast.
