Description

Technical Field

[0001] The present invention relates to data processing technology in the field of financial technology, and in particular to an idempotent anti-duplication method, device, equipment, medium and product for accounting. Background Art

[0002] With the popularization of electronic transactions and economic development, more and more users are shopping online through mobile terminals, and online shopping has become an important form of shopping.

[0003] Online purchases in FinTech scenarios typically involve two processes: ordering and payment. During the payment process, duplicate payments can occur, leading to additional logistics costs, transaction negotiation, and return costs, significantly impacting the merchant's reputation and user experience. Duplicate payments can occur due to: 1) customer error. For example, after clicking the order button, before receiving payment information from the backend, the order button is not disabled and the order status is unavailable, causing the user to click the order button repeatedly. 2) Payment channel timeouts. For example, a user may select a payment method at the checkout page and complete the payment through the corresponding payment channel, but the channel returns an asynchronous notification timeout. The payment system has not yet updated the payment status, leaving the user unclear about the order's success, resulting in multiple payments. Users may make duplicate payments due to network fluctuations or data delays. Some unscrupulous individuals may exploit various methods to duplicate payments, resulting in losses for merchants or users. Therefore, accurately preventing duplicate payments and ensuring payment security are pressing issues. Summary of the Invention

[0027] Figure 1 This is a flow chart of an idempotent anti-duplicate method for accounts provided by the present invention. This embodiment can be applied to avoid duplicate payment problems, improve the security of payment systems, etc. The method can be executed by the idempotent anti-duplicate device for accounts provided by the present invention. The device can be implemented in the form of hardware and / or software. In a specific embodiment, the device can be integrated into an electronic device. The following embodiments will be described using the device integrated into an electronic device as an example. Figure 1 , the method specifically comprises the following steps:

[0028] S101: When a payment request for a service to be paid is received, a processing solution corresponding to the payment request is determined based on the service key and technical key included in the payment request.

[0029] Among them, pending payment services can be understood as orders that require payment, such as payment orders generated after a purchase instruction is issued, or payment orders generated after a payment instruction is issued. Payment requests can be understood as payment instructions for pending payment services, indicating the user's current willingness to pay to complete the order. Business keys and technical keys can be understood as two key pieces of information contained in an order. Business keys are business-related information about the order, including but not limited to the order number and order generation time. Technical keys are technical-related information about the order, including but not limited to the order type and order amount. These two pieces of information work together to determine the processing solution for the payment request.

[0030] In order to prevent the problem of repeated payment for the same order, the present invention will parse the payment request to determine whether the payment request is the first payment instruction for the business to be paid. Different order payment processes are formulated for different types of payment requests. For example, for the first payment instruction, the normal payment process can be directly triggered. For the second payment instruction, it is necessary to determine whether the corresponding business has been successfully paid, that is, to trigger the payment anti-duplicate process. The purpose of this setting is to reduce the probability of repeated payment on the basis of ensuring the smooth execution of the payment work.

[0031] The processing scheme of the present invention is a first processing scheme or a second processing scheme. The first processing scheme is used to start the payment process, and the second processing scheme is used to start the idempotent anti-duplicate process.

[0032] In one embodiment, S101 may specifically include: upon receiving a payment request for a business to be paid, determining a historical payment business set, wherein the historical payment business set includes at least one historical payment business, and the historical payment business includes a historical business key value and a historical technical key value; determining whether there is a matching payment business for the business to be paid in the historical payment business set, wherein the matching payment business is a payment business in which the historical business key value in the historical payment business set is the same as the business key value of the business to be paid and / or the historical technical key value is the same as the technical key value of the business to be paid; if there is no matching payment business for the business to be paid in the historical payment business set, determining that the processing solution is the first processing solution; if there is a matching payment business for the business to be paid in the historical payment business set, determining that the processing solution is the second processing solution.

[0033] Among them, the historical payment business set can be understood as all payment logs within the data processing period, including each payment business and detailed payment information of each payment business (payment successful, payment in progress, payment failed, etc.), which is used to determine whether the payment request of the current pending payment business is the first payment instruction and to quickly determine the payment result of the business corresponding to the second payment instruction. The matching payment business and its historical business key value and the historical business key value are used to indicate the historical payment information of the pending payment business. Once the business key value or technical key value of the pending payment business is the same as a business in the historical payment business set, that is, the pending payment business has found a matching payment business in the historical payment business set, it proves that the pending payment business has a payment record, and idempotent anti-duplicate is required to avoid repeated payment. The processing solution is determined to be the second processing solution. If the business key value or technical key value of the pending payment business is not recorded in the historical payment business set, that is, the pending payment business has not found a matching payment business in the historical payment business set, it proves that the pending payment business has no payment record, and the payment process can be triggered directly without the problem of repeated payment. The processing solution is determined to be the first processing solution.

[0034] For example, assuming that the historical payment business set includes three businesses, the historical business key value of historical payment business 1 is A1, and the historical technical key value is B1, the historical business key value of historical payment business 2 is A2, and the historical technical key value is B2, and the historical business key value of historical payment business 3 is A3, and the historical technical key value is B3. If the business key value of the business to be paid is A4, A5, etc., which are different from A1, A2, and A3, and the technical key value is B4, B5, etc., which are different from B1, B2, and B3, then it is considered that there is no matching payment business for the business to be paid in the historical payment business set, the payment request for the business to be paid is triggered for the first time, and the processing solution is the first processing solution. If the business key value of the business to be paid is any one of A1, A2, and A3 and / or the technical key value is any one of B1, B2, and B3, then it is considered that there is a matching payment business for the business to be paid in the historical payment business set, and idempotent anti-duplicate processing is required. The processing solution is the second processing solution, and the historical payment business with the same technical key value and / or business key value as the business to be paid is determined to be the matching payment business.

[0035] The advantage of this setting is that it can quickly, efficiently and specifically determine the processing procedures for pending payments, ensuring the security and real-time nature of account payment results.

[0036] Furthermore, the same key values ​​include three situations: the same technical key values, the same business key values, and the same technical key values ​​and business key values. The three situations can be divided into two situations based on whether the business key values ​​are the same or different. In order to improve the efficiency of idempotent anti-duplicate work, the present invention sets different idempotent anti-duplicate schemes for different situations. Specifically, the second processing scheme includes a business idempotent processing scheme and a technical idempotent processing scheme. Determining the second processing scheme includes: determining whether the historical business key value of the matching payment business is the same as the business key value of the business to be paid; if the historical business key value of the matching payment business is the same as the business key value of the business to be paid, then determining that the second processing scheme is a business idempotent processing scheme; if the historical business key value of the matching payment business is different from the business key value of the business to be paid, then determining that the second processing scheme is a technical idempotent processing scheme.

[0037] The business idempotent processing scheme indicates that the current payment request for a pending payment service has a duplicate business key value and requires business idempotent processing. The technical idempotent processing scheme indicates that the current payment request for a pending payment service has a duplicate technical key value and requires technical idempotent processing. The benefit of this setup is that it refines and categorizes the processing methods for re-payment requests based on their type, enabling better and more targeted determination of the payment results for each payment request for the pending payment service.

[0038] S102: Based on the first processing solution or the second processing solution, start the payment process or the idempotent anti-duplicate process, process the business key value and the technical key value of the payment request, and obtain the payment result of the business to be paid.

[0039] The first and second processing schemes are separate processes for different types of payment requests, designed to achieve global account duplication prevention and idempotency within a distributed architecture. The first processing scheme corresponds to the payment process, while the second processing scheme corresponds to the idempotent duplication prevention process. Specifically, the payment process indicates that the payment is a first payment, and the payment result obtained by executing this process is the first payment result; the idempotent duplication prevention process indicates that the payment is a second payment, and the payment result obtained by executing this process is the second payment result.

[0040] Exemplarily, when the processing scheme is the first processing scheme, the payment process is initiated, the payment process for the pending payment transaction is executed based on the business key and technical key of the payment request, and a first payment result is determined based on the payment status. For example, if the payment process is successfully executed, the first payment result is determined to be a payment success; if the payment process fails, the first payment result is determined to be a payment failure. When the processing scheme is the second processing scheme, the idempotent anti-duplicate process is initiated, the anti-duplicate payment process for the pending payment transaction is executed based on historical payment status (which can be understood as at least one first payment result of the pending payment transaction), the business key and technical key of the payment request, and a second payment result is determined based on the payment status. It is worth noting that the same transaction can only be successfully paid once. The second payment result is determined by determining whether the first payment result is successful. If the first payment result is a payment success, the payment for the pending payment transaction is determined to have been completed, and the second payment result is a failure. If the first payment result is a payment failure, the payment process is continued using the business key and technical key, and the second payment result is determined based on the payment status. Similarly, if the payment process is successfully executed, the second payment result is determined to be a payment success; if the payment process fails, the second payment result is determined to be a payment failure. The advantage of this setting is that it can effectively avoid the problem of duplicate payment.

[0041] In one embodiment, based on the first processing scheme, the payment process is initiated, the business key value and technical key value of the payment request are processed, and the payment result of the business to be paid is obtained, including: generating a first payment instruction based on the business key value and technical key value of the payment request, sending the first payment instruction to the accounting processing device, and receiving first payment feedback information from the accounting processing device; based on the first payment feedback information, determining the first payment result of the business to be paid.

[0042] The first payment instruction can be understood as an instruction carrying payment request information for the business to be paid, the account processing device can be understood as an account accounting or payment server, the first payment feedback information can be understood as the payment conclusion of the business to be paid obtained by the account processing device in response to the first payment instruction and after processing the payment request information carried in the first payment instruction, and the payment result application indicates the payment result of the business to be paid. For example, the payment conclusion can be the execution status of the business key value, the execution status of the technical key value, and the execution status of the business key value and the execution status of the technical key value are used to determine the payment result of the business to be paid.

[0043] Specifically, when the first payment feedback information indicates that the business key and technical key of the payment request were successfully executed, the first payment result is determined to be payment successful; when the first payment feedback information indicates that the business key and technical key of the payment request were unsuccessful, the first payment result is determined to be payment failed; and when the first payment feedback information indicates that the execution status of the business key and technical key of the payment request is unknown, the first payment result is determined to be payment in progress. The advantage of this setting is that the payment result of the pending payment business can be obtained accurately and specifically.

[0044] Furthermore, before generating the first payment instruction based on the business key value and technical key value of the payment request, the key value information of the technical key value of the payment request is written into the database, and the key value information of the business key value of the payment request is written into the distributed cache device and the database; after obtaining the first payment result of the business to be paid, the key value information of the distributed cache device and the database is adjusted based on the first payment result; wherein, the key value information is used to determine the payment result of the re-payment work, and when the first payment result is a successful payment, the key value information in the distributed cache device and the database is updated based on the first payment result, that is, the key value information of the business key value in the distributed cache device is updated to success, and the key value information of the business key value and the technical key value in the database is updated to success. The key value information in the database can be understood as anti-duplication details; when the first payment result is a failed payment, the key value information in the distributed cache device is deleted and the key value information in the database is updated, that is, the information of the business key value in the distributed cache device and the database is deleted, and the technical key value is updated to failure. This setting will not affect subsequent payment work and will also leave a complete payment record, thereby ensuring the traceability of transaction data.

[0045] In another embodiment, based on the second processing scheme, an idempotent anti-duplicate process is started, and the business key value and technical key value of the payment request are processed to obtain the payment result of the business to be paid, including: when the second processing scheme is a technical idempotent processing scheme, determining that the second payment result is a business rejection; when the second processing scheme is a business idempotent processing scheme, determining whether the historical technical key value of the matching payment business is the same as the technical key value of the business to be paid; if the historical technical key value of the matching payment business is the same as the technical key value of the business to be paid, then determining that the second payment result is the payment result of the matching payment business, that is, the payment result of the idempotent first payment; if the historical technical key value of the matching payment business is different from the technical key value of the business to be paid, then determining whether the payment result of the matching payment business is a payment failure; when the payment result of the matching payment business is not a payment failure, determining that the second payment result is a payment failure, and returning the transaction identification information of the business to be paid; when the payment result of the matching payment business is a payment failure, generating a second payment instruction based on the business key value and technical key value of the payment request, sending the second payment instruction to the accounting processing device, and determining the second payment result based on the second payment feedback information of the accounting processing device.

[0046] Similarly, the second payment instruction carries payment request information for the pending payment transaction. The second payment feedback information is the payment conclusion for the pending payment transaction obtained by the accounting processing device in response to the second payment instruction and after processing the payment request information carried in the second payment instruction. The payment result should indicate the payment result for the pending payment transaction. Specifically, when the first payment result is successful, the second payment result will fail to avoid duplicate payments. When the first payment result fails, the payment process will continue using the technical key and business key in the second payment request, and the second payment result will be determined based on the information fed back by the accounting processing device.

[0047] Table 1 shows the payment status relationship, indicating the correspondence between payment results and payment request information. The transaction scenario is used to indicate whether the payment request is submitted for the first time. The business key represents the business key value, the technical key represents the technical key value, the execution status represents the execution status of the business key value and the technical key value, the execution result represents the payment result, the database represents the conclusion stored in the database, the slash indicates that the execution result is not written to the database, the written information can be understood as anti-duplicate details, and the serial number can be understood as key value information. Table 1 distinguishes between resubmission and secondary submission. In fact, the secondary submission can also follow the resubmission process, and the present invention does not limit this.

[0048] Table 1 Payment status relationship

[0049]

[0050]

[0051] The main content of Table 1 is as follows: when making the first payment, the payment result is determined based on the execution status of A1 and B1. When making the second payment, the payment result of the second payment is determined based on the key value information and the first payment result. If the key value information is A1 and B1, the first payment result is directly fed back. If the key value information is A2 and B1, the payment is rejected. If the key value information is A1 and B2, it is first determined whether A1 and B1 fail. If A1 and B1 succeed, it is directly determined that A1 and B2 fail. Only if A1 and B1 fail will A1 and B2 be used to continue the payment process, and the payment result is determined based on the execution status of A1 and B2.

[0052] The distributed cache device of the present invention can be a REDIS (an in-memory data structure storage database) cache, which connects multiple distributed systems to achieve the purpose of data transfer and caching, and realizes the global idempotence and anti-duplicate of accounts under the distributed system. The advantages of adopting this design are: 1) Solving the anti-duplicate protection problem under the distributed architecture. When the REDIS cache fails, the local anti-duplicate of the database can be used to ensure the availability of anti-duplicate. 2) Solving the global anti-duplicate problem under the distributed architecture. Anti-duplicate filtering of payment services based on the REDIS distributed cache can improve the performance of business processing and reduce the pressure on the database.

[0053] S103: Control the information interaction interface to display the payment result.

[0054] Specifically, the information interaction interface can be understood as an information display screen. The purpose of controlling the information interaction interface to display the payment results is to visualize the payment results, so that the payer can understand the payment status of the pending payment business and take corresponding processing measures in a timely manner.

[0055] It's worth noting that if the payment result is a failure, the information interaction interface can also be controlled to display the reason for the payment failure, allowing the payer to adjust the payment request or the business parameters of the pending payment. For example, if the displayed amount is too large, the payment can be made in batches. If the balance is insufficient, the payer can be prompted to resolve the balance issue before initiating the payment process.

[0056] The technical solution of this embodiment determines whether the payment request is triggered for the first time through the payment request business key value and technical key value of the business to be paid. If it is triggered for the first time, the payment process is started. If it is triggered for the second time, the idempotent anti-duplicate process is started to avoid the problem of repeated payments caused by the payment system responding to multiple payment requests, ensure the security of the payment work, and visualize the payment results, so that the payment requester can understand the payment status of the business to be paid in a timely manner, thereby improving the payment experience of the payment requester.

[0057] Figure 2 This is a schematic diagram of a payment process provided by the present invention. Figure 2 It is a complete business payment process, such as Figure 2As shown in the figure, the payment process mainly includes:

[0058] 1. The product server sends a payment instruction to the payment server.

[0059] The essence of this step is to send the payer's payment request to the payment service. The payment instruction is essentially the business key and technical key of the business to be paid.

[0060] 2. The payment service writes the business key value into the distributed cache.

[0061] 3. The distributed cache feeds back the writing status of the business key value to the payment business.

[0062] Figure 2 The business key value is written successfully.

[0063] 4. The payment service writes the business key and technical key into the database.

[0064] 5. The database provides feedback to the payment service on the writing status of technical key values ​​and business key values.

[0065] Similarly, Figure 2 The writing status of the technical key value and business key value is successful.

[0066] 6. The payment service sends payment instructions to the core accounting service.

[0067] 7. The core accounting service sends the payment conclusion to the payment service.

[0068] The payment conclusion is whether the payment is successful.

[0069] 8. The payment service updates / deletes the key-value information in the distributed cache based on the payment conclusion.

[0070] Specifically, when the payment is successful, the key value information in the distributed cache is updated, and when the payment fails, the key value information in the distributed cache is deleted.

[0071] 9. The distributed cache sends the key-value information to the payment service.

[0072] 10. The payment service updates / deletes the key value information in the database based on the payment conclusion.

[0073] Specifically, when the payment is successful, the key value information in the distributed cache is updated, and when the payment fails, the key value information in the distributed cache is deleted. It is worth noting that the transaction details status in the database will be updated regardless of success or failure.

[0074] 11. The database sends the key-value information to the payment service.

[0075] 12. Payment service product and service feedback payment results.

[0076] Specifically, the feedback of payment results can be understood as a visual display of the payment results, which makes it easier for the payer to understand the payment status of the pending payment business.

[0077] The beneficial effects of the present invention include: 1) Supporting service idempotence. Specifically, for payment data submitted repeatedly, the original data processing result is returned by default, and the response data is displayed to indicate that the data has been processed. In addition, when it is determined that it is an idempotent request, the consistency of the business elements will be checked. If the business elements are inconsistent, the transaction will be rejected, and the user will be reminded to check the business elements to prevent accounting risks. 2) Global anti-duplication is performed based on the REDIS cache. Specifically, if the insertion of the global anti-duplication key value fails, the exception return message is encapsulated. If the payment fails, the global business anti-duplication key value is deleted for subsequent retries. If successful or unknown, the global business anti-duplication is not deleted, and the original transaction processing result is returned idempotently. 3) Database anti-duplication is implemented based on the business anti-duplication table. Ensure that the system can route the same transaction to the same database shard based on the business flow. Within the same shard, it can be determined whether it is the same business based on the primary key of the business anti-duplication table. If it is the same business and the payment status is unknown or successful, the original processing result is returned idempotently. 4) Support service failure redo. Specifically, for failed payment services, the business flow remains unchanged, and it supports replacing the technical flow and re-initiating. When the system determines that the original transaction has failed, it can continue the payment process to avoid repeated payments while ensuring the payment quality of the business.

[0078] Figure 3 This is a schematic diagram of the structure of an idempotent anti-duplicate device for accounting services provided by the present invention. Figure 3 As shown, the device includes: a solution determination module 201, a result determination module 202 and a result display module 203.

[0079] The solution determination module 201 is used to determine the processing solution corresponding to the payment request based on the business key value and technical key value included in the payment request when receiving the payment request for the service to be paid, wherein the processing solution is the first processing solution or the second processing solution, the first processing solution is used to start the payment process, and the second processing solution is used to start the idempotent anti-duplicate process.
