Description

Technical Field

[0001] The present invention relates to the field of data processing technology, and in particular to a method, apparatus, computer equipment, and computer-readable storage medium for processing transaction data based on a POS terminal. Background Art

[0002] In the existing POS-based transaction data processing process, transaction results are returned in the following manner: when multiple POS devices simultaneously send transaction data processing requests to the transaction system, the transaction system, through synchronous calls, returns an intermediate status of "processing" to each of the POS devices. The transaction results are then notified to the upstream system via asynchronous messages, which then return the results to the POS devices. However, this transaction result return method has the following drawbacks: the upstream system may return a transaction result that should have been returned to POS device A to POS device B, making it impossible to return every transaction result to the correct POS device. This results in low transaction result accuracy, long transaction data processing time, and low transaction data processing efficiency. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a transaction data processing method, device, computer equipment and computer-readable storage medium based on a POS terminal, which is used to solve the problem that the existing method of returning transaction results through message middleware easily leads to low accuracy and low efficiency of transaction results.

[0047] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, 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 only used to explain the present invention and are not intended to limit the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0048] It should be noted that the descriptions of "first", "second", etc. in the embodiments of the present invention are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0049] In the description of the present invention, it should be understood that the numerical labels before the steps do not identify the order in which the steps are executed, but are only used to facilitate the description of the present invention and to distinguish each step, and therefore should not be understood as a limitation of the present invention.

[0050] Example 1

[0051] See also Figure 1 , shows a flowchart of the steps of the transaction data processing method based on the POS terminal according to an embodiment of the present invention. It is understood that the flowchart in this method embodiment is not intended to limit the order of execution of the steps. The following example description is based on a computer device as the execution subject, as follows:

[0052] like Figure 1 As shown, the transaction data processing method based on the POS terminal may include steps S100 to S106, wherein:

[0053] Step S100: sending transaction data to the transaction system through the target POS access terminal, wherein the transaction data carries target subject data, wherein the target subject data includes the target POS access terminal identifier and transaction number data.

[0054] In an exemplary embodiment, to improve transaction data processing efficiency, POS access points are typically clustered, including POS access point A, POS access point B, POS access point C, ..., POS access point N. Different POS access points can establish TCP connections with different POS terminals. After establishing a TCP connection, each transaction conducted at a POS terminal sends the corresponding transaction data to the corresponding POS access point. TCP stands for Transmission Control Protocol; before establishing a TLS or SSL (Secure Sockets Layer) connection in a TCP-based HTTPS request, a TCP three-way handshake is performed to establish the connection.

[0055] See also Figure 2The method further includes pre-establishing a communication connection between the POS terminal and the POS access terminal, wherein the step of establishing the communication connection further includes steps S200 to S204, wherein: step S200, sending a synchronization sequence number data packet to the POS access terminal by the POS terminal to request a connection; wherein the synchronization sequence number data packet is used to request a connection from the POS access terminal; the synchronization sequence number data packet carries the POS terminal identifier; step S202, receiving the synchronization sequence number data packet by the POS access terminal, and generating and returning a handshake confirmation packet to the POS terminal based on the synchronization sequence number data packet; wherein the handshake confirmation packet indicates that the POS access terminal confirms the establishment of a connection with the POS terminal; and step S204, receiving the handshake confirmation packet by the POS terminal, and generating and returning a confirmation character packet to the POS access terminal based on the handshake confirmation packet, so that the POS terminal establishes a communication connection with the POS access terminal; wherein the confirmation character packet indicates that the POS terminal receives the confirmation connection request from the POS access terminal and that the POS terminal confirms the establishment of a communication connection with the POS access terminal. In this embodiment, the POS terminal identifier can be the POS terminal's POS number, which represents a physical POS device. For example, the topic data includes: POS access terminal identifier (such as the POS access terminal IP address) and transaction number data (such as the POS number and transaction number). For example, the topic data is [POS access terminal IP address: POS number: transaction number].

[0056] After the POS terminal confirms that a communication connection has been established with the POS access terminal, the method further includes: if the POS access terminal does not receive any data sent by the corresponding POS terminal within a preset time period, generating and sending a TCP detection packet to the corresponding POS terminal to evaluate whether the corresponding POS terminal is alive.

[0057] Step S102: receiving and processing the transaction data through the transaction system to obtain a transaction result.

[0058] In an exemplary embodiment, the transaction system parses and calculates the transaction data according to a preset calculation rule therein, and obtains a transaction result.

[0059] Step S104: The transaction result and the target subject data are stored in a redis component through the transaction system, so that the redis component matches the target POS access terminal according to the target subject data and sends the transaction result to the target POS access terminal.

[0060] To ensure fast communication between the POS access point and the Redis component, the method includes pre-establishing a persistent connection between each POS access point and the Redis component. Each POS access point, acting as a subscriber, subscribes to topic data from the Redis component. After obtaining the transaction results, the transaction system stores them in its database and publishes the transaction results and target topic data to the Redis component. After receiving the target topic data, the Redis component matches the POS access point and sends the transaction results to the corresponding target POS access point via the persistent connection between the POS access point and the Redis component.

[0061] In an embodiment of the present invention, the wildcard matching rule of the redis component is that the actual subscription of the pos access terminal to the redis component is [pos access terminal IP: Pos number: *], where "*" is a wildcard; the wildcard matching rule is to match the pos access terminal related to the pos access terminal IP (such as pos access terminal A) according to the actually subscribed subject data.

[0062] See also Figure 3 , the matching of the target POS access terminal according to the target subject data can also be achieved through the following operations: step S300, matching the target POS access terminal identifier in the target subject data with each POS access terminal identifier pre-stored in the redis component; and step S302, if there is a consistent match in the matching result, then the POS access terminal in the redis component that matches the target POS access terminal identifier is determined as the target POS access terminal. In this embodiment, the subsystems that need to communicate are decoupled through the POS access terminal, the transaction system, and the redis component, and each system can be managed independently without affecting the management of the overall system. And the decoupling of each subsystem allows the application programs of each system to focus more on its core functions, effectively improving the development efficiency and quality of each subsystem. Step S106, receiving the transaction result returned by the redis component through the target POS access terminal, and returning the transaction result to the target POS terminal associated with the target POS access terminal.

[0063] In an exemplary embodiment, the transaction result includes a target POS number; Figure 4, the step S106 of receiving the transaction result returned by the redis component through the target POS access terminal and returning the transaction result to the target POS terminal associated with the target POS access terminal may also include steps S400 to S404, wherein: step S400, querying whether there is a target TCP connection associated with the target POS number through the target POS access terminal according to the target POS number in the transaction result; step S402, if it is determined that there is a target TCP connection associated with the target POS number, obtaining the target POS terminal corresponding to the target POS number; and step S404, returning the transaction result to the target POS terminal through the target TCP connection. In this embodiment, if there is no TCP connection associated with the target POS number, the transaction result is stored in the database of the target POS access terminal, and within a preset time period, it is repeatedly queried whether there is a TCP connection associated with the target POS number. If the TCP connection associated with the target POS number is still not found after the preset number of queries, an abnormal result is generated and saved in the database.

[0064] In order to improve the user experience of POS devices, please refer to Figure 5 , the method also includes: step S500, if the target POS access terminal does not receive the transaction result within the preset time, then waiting data is returned to the POS terminal, and the waiting data indicates that the transaction is being processed; and step S502, if the POS access terminal does not receive the transaction result after returning the waiting data to the POS terminal for a preset number of times, then a transaction result query request is generated and sent to the transaction system through the POS access terminal, so that the transaction system responds to the transaction result query request to generate and return the transaction result. Among them, the preset number of times can be 3 times. Through the data processing feedback mechanism of the POS access terminal, the POS access terminal will initiate a transaction result query when the transaction result cannot be queried for three consecutive times. The POS access terminal does not need to repeatedly query the transaction result while waiting for the transaction result; the query of the POS access terminal is reduced, the time for users to wait for transaction results is effectively shortened, and the user experience of the POS device is further improved; and the resource loss of the POS access system and the transaction system is saved.

[0065] The level of different POS terminals determines the speed of message return; please refer to Figure 6The method further includes: step S600, receiving the transaction data sent by multiple POS terminals through the transaction system, wherein the target subject data in each transaction data also includes a corresponding processing level tag; step S602, sorting the multiple transaction data according to each processing level tag through the transaction system; step S604, allocating a corresponding computing power server to each transaction data according to a preset load balancing rule and the processing level tag corresponding to each transaction data through the transaction system; the computing power server is used to process the received transaction data; and step S606, calling the computing power server through the transaction system to process the received transaction data and generate a corresponding transaction result. In this embodiment, different transaction data are processed according to the priority of different information, which can improve the user experience of the POS device to a certain extent.
