[0027] Figure 1 This is a flowchart 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 in an electronic device. The following embodiments will be described by taking the device integrated in 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 scheme corresponding to the payment request is determined based on the service key value and the technical key value included in the payment request.

[0029] Among them, the pending payment business can be understood as an order that needs to be paid, for example, a payment order generated after a purchase instruction is issued, a payment order generated after a payment instruction is issued, etc. The payment request can be understood as a payment instruction for the pending payment business, which is used to indicate that the user is currently inclined to pay to complete the order. The business key and the technical key can be understood as two key information contained in the order. The business key is the business information of the order, including but not limited to the order number and order generation time of the order. The technical key can be understood as the technical information of the order, including but not limited to the order type and order amount of the order. The two types of information work together to determine the processing plan for the payment request.

[0030] In order to prevent the problem of duplicate 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 duplicate payments on the basis of ensuring the smooth execution of 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 the historical payment business set whose historical business key value is the same as the business key value of the business to be paid and / or whose 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 success, payment in progress, payment failure, etc.), which is used to determine whether the payment request of the current business to be paid is the first payment instruction and 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 business to be paid. Once the business key value or technical key value of the business to be paid is the same as a business in the historical payment business set, that is, the business to be paid has found a matching payment business in the historical payment business set, it proves that the business to be paid has a payment record, and idempotent anti-duplicate is required to avoid repeated payment, and the processing solution is determined to be the second processing solution. If the business key value or technical key value of the business to be paid is not recorded in the historical payment business set, that is, the business to be paid has not found a matching payment business in the historical payment business set, it proves that the business to be paid has no payment record, and the payment process can be directly triggered, and there will be no problem of repeated payment, and the processing solution is determined to be the first processing solution.

[0034] For example, assuming that the historical payment business set includes 3 businesses, the historical business key value of historical payment business 1 is A1, the historical technical key value is B1, the historical business key value of historical payment business 2 is A2, the historical technical key value is B2, 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, and the payment request for the business to be paid is triggered for the first time, and the processing scheme is the first processing scheme. 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 scheme is the second processing scheme, and the historical payment business with the same technical key value and / or the same 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 flow of the business to be paid, ensuring the security and real-time nature of the account payment results.

[0036] Furthermore, the same key values ​​include 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 according to the same business key values ​​and different business key values. 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 not the same as the business key value of the business to be paid, then determining that the second processing scheme is a technical idempotent processing scheme.

[0037] Among them, the business idempotent processing scheme is used to indicate that the current payment request of the pending payment service is a request with a repeated business key value, and business idempotent processing is required, and the technical idempotent processing scheme is used to indicate that the current payment request of the pending payment service is a request with a repeated technical key value, and technical idempotent processing is required. The advantage of this setting is that the processing method of the re-payment request is refined and classified according to the type of the re-payment request, which can better and more targetedly determine the payment results of each payment request of the pending payment service.

[0038] S102: Based on the first processing scheme or the second processing scheme, 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] Among them, the first processing scheme and the second processing scheme are different processing procedures set for different types of payment requests, which are used to perform global anti-duplicate and global idempotency of accounts under a distributed architecture. The first processing scheme corresponds to the payment process, and the second processing scheme corresponds to the idempotent anti-duplicate process. Specifically, the payment process is used to indicate that the business to be paid is the first payment work, and the payment result obtained by executing the process is the first payment result; the idempotent anti-duplicate process is used to indicate that the business to be paid is the second payment work, and the payment result obtained by executing the process is the second payment result.

[0040] Exemplarily, when the processing scheme is the first processing scheme, the payment process is started, the payment process of the business to be paid is executed according to the business key value and the technical key value of the payment request, and the first payment result is determined according to the payment situation. For example, if the payment process is successfully executed, the first payment result is determined to be a successful payment, and 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 started, and the anti-duplicate payment process of the business to be paid is executed according to the historical payment situation (which can be understood as at least one first payment result of the business to be paid), the business key value and the technical key value of the payment request, and the second payment result is determined according to the payment situation. It is worth noting that the same business can only be successfully paid once, and the process of determining the second payment result is to determine whether the first payment result is successful. If the first payment result is a successful payment, it is determined that the payment of the business to be paid has been completed, and the second payment result is a failure. If the first payment result is a payment failure, the payment process is continued to be executed using the business key value and the technical key value, and the second payment result is determined according to the payment situation. Similarly, when the payment process is successfully executed, the second payment result is determined to be a successful payment, and when 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 a first processing scheme, a payment process is initiated, the business key value and the 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 the technical key value of the payment request, sending the first payment instruction to an accounting processing device, and receiving first payment feedback information from the accounting processing device; based on the first payment feedback information, determining a first payment result of the business to be paid.

[0042] The first payment instruction can be understood as an instruction carrying payment request information of 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 account processing device responding to the first payment instruction, and obtaining a payment conclusion of the business to be paid 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 are executed successfully, the first payment result is determined to be a successful payment; when the first payment feedback information indicates that the business key and technical key of the payment request are executed unsuccessfully, the first payment result is determined to be a failed payment; when the first payment feedback information indicates that the execution status of the business key and technical key of the payment request is in an unknown state, the first payment result is determined to be a payment in progress state. The advantage of such a setting is that the payment result of the business to be paid 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, and the key value information in the database can be understood as anti-duplicate details; when the first payment result is a payment failure, 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. Such a 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 account processing device, and determining the second payment result based on the second payment feedback information of the account processing device.

[0046] Similarly, the second payment instruction is an instruction that carries the payment request information of the business to be paid, the second payment feedback information is the payment conclusion of the business to be paid obtained by the account processing device in response to the second payment instruction and after processing the payment request information carried in the second payment instruction, and the payment result application indicates the payment result of the business to be paid. Specifically, when the first payment result is successful, in order to avoid the problem of repeated payment, the second payment result fails. When the first payment result fails, the technical key value and business key value in the second payment request are used to continue the payment work, and the second payment result is determined according to the information fed back by the account processing device.

[0047] Table 1 shows the payment status relationship, indicating the corresponding relationship between payment results and payment request and other information. The transaction scenario is used to indicate whether the payment request is submitted for the first time. The business key indicates the business key value, the technical key indicates the technical key value, the execution status is the execution status of the business key value and the technical key value, the execution result is the payment result, the database indicates 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 contents of Table 1 are as follows: when making the first payment, the payment result is determined according to the execution status of A1 and B1. When making the second payment, the payment result of the second payment is determined in combination with 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. When A1 and B1 succeed, it is directly determined that A1 and B2 fail. Only when A1 and B1 fail will A1 and B2 be used to continue the payment process, and the payment result is determined according to 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, connecting multiple distributed systems to achieve the purpose of data transfer and caching, and realize the global idempotence and anti-duplicate of accounts under distributed systems. The advantages of adopting this design are: 1) Solving the anti-duplicate protection problem under 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 distributed architecture, anti-duplicate filtering of payment services based on the REDIS distributed cache can improve the performance of business processing and reduce database pressure.

[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 business to be paid and take corresponding processing measures in a timely manner.

[0055] It is worth noting that if the payment result is payment failure, the information interaction interface can also be controlled to display the reason for payment failure, so that the payer can adjust the payment request or the business parameters of the business to be paid. For example, if the displayed amount is too large, it can be paid in batches. If the balance is insufficient, the payer can be prompted to start the payment process after resolving the balance problem.

[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 time, thereby improving the payment experience of the payment requester.

[0057] Figure 2 is a schematic diagram of a payment process provided by the present invention, Figure 2 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 demand 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 writing status of the business key value is successful.

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

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

[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 refers to whether the payment is successful.

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

[0070] Specifically, when the payment is successful, the key value information of the distributed cache is updated, and when the payment fails, the key value information of 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 of the distributed cache is updated, and when the payment fails, the key value information of 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 is convenient 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 judged 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-duplicate is performed based on REDIS cache. Specifically, if the insertion of the global anti-duplicate key value fails, the abnormal return message is encapsulated. If the payment fails, the global business anti-duplicate key value is deleted for subsequent retry. If successful or unknown, the global business anti-duplicate is not deleted, and the original transaction processing result is returned idempotently. 3) Database anti-duplicate is implemented based on the business anti-duplicate table. Ensure that the system can route the same transaction to the same database shard according to the business flow. In the same shard, it can be determined whether it is the same business according to the primary key of the business anti-duplicate table. If it is the same business and the payment status is unknown or successful, the idempotent returns the original processing result. 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, the payment process can be continued to avoid duplicate payments while ensuring the payment quality of the business.

[0078] Figure 3 Schematic diagram of the structure of an idempotent anti-duplicate device for accounts 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.
