Transaction data processing method and device, computer equipment and readable storage medium

Abstract

The invention discloses a transaction data processing method. The method comprises the following steps: pre-determining a transaction state synchronization unit formed by combining front and rear adjacent systems in a transaction data circulation channel in sequence; in the same transaction state synchronization unit, the method comprises the following steps: processing transaction-related data received in a front system through a preset encryption algorithm, and sending the processed transaction-related data to a rear system; After receiving the encrypted data related to the transaction, therear system returns a delivery notification message to the front system; After receiving the delivery notification message, the front system adjusts the transaction state in the front system into a first preset state; The processing result information is returned to the front system after the data related to the transaction is processed by the rear system; and after receiving the processing resultinformation, the front system adjusts the transaction state in the front system into a second preset state. According to the invention, the problem of transaction abnormity caused by transaction datatransfer abnormity in the prior art can be solved, normal and safe transfer of transaction data is ensured, and the normality and accuracy of transaction are ensured.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a transaction data processing method, device, computer equipment and readable storage medium. Background technique [0002] In the circulation process of existing transaction data, for example, from the time a transaction request is initiated through a POS machine until the transaction request reaches the bank system where the bank card where the transaction actually occurs, it usually needs to be forwarded through the accepting party system and the transfer party. system, the core system of the transfer party, and the card issuer system, and during the data transfer process between the above-mentioned adjacent systems, it is likely that due to problems such as data channel blockage and network interruption, the transaction data does not reach the target system, transaction data After the target system is reached, due to the lack of data, it cannot handle the abnormal t...

Problems solved by technology

[0002] In the circulation process of existing transaction data, for example, from the time a transaction request is initiated through a POS machine until the transaction request reaches the bank system where the bank card where the transaction actually occurs, it usually needs to be forwarded through the accepting party system and the transfer party. system, the core system of the transfer party, and the card issuer system, and during the data transfer process between the above-mentioned adjacent systems, it is likely that due to problems such as data channel blockage and network interruption, the transaction data does not reach the target system, transaction data After the target system is reached, due to the lack of data, it is impossible to handle the abnormal transaction data flow, which leads to the occurrence of abnormal transaction

[0003] In related technologies, there is no effective solution to the problem of transaction abnormality caused by abnormal transaction data flow.
