Method embodiment
According to an embodiment of the present invention, a concurrent payment method is provided, fig. 1 is a flowchart of the concurrent payment method according to the embodiment of the present invention, and as shown in fig. 1, the concurrent payment method according to the embodiment of the present invention specifically includes:
step 101, receiving an order payment request sent by a user through a background application system, legally checking order payment information carried in the order payment request, recording the order after the order payment request is successfully checked, storing the order in a database, setting a first distribution lock for the current payment order, rejecting other payment requests of the current order through the first distribution lock, and calling a payment system;
in step 101, the order payment request comprises: single order payment requests and batch order payment requests;
therefore, in step 101, the payment amount and the order unique identifier of the single order payment request are saved in the database after the verification is successful; or after the verification is successful, saving the batch number and the payment sum of the batch order payment request to a database, wherein the batch number is as follows: the order of each order in the batch of orders uniquely identifies the constituent string.
102, performing payment verification on order payment information through a payment system, setting a second distribution lock for a currently paid order, rejecting other payment requests of the current order through the second distribution lock, respectively recording platform transaction details of the order into one or more preset transaction record tables after the payment verification is passed, setting a unique index for the transaction record tables by using an order number, and feeding back a payment result to a user through a background application system according to a verification result; wherein, the transaction record table specifically includes: a batch record table batch _ pay _ info, a order record table batch _ pay _ order _ info, and the like.
Step 103, according to the processing logic required for completing the current payment recorded in the transaction record table, one or more preset message queues are called, the corresponding processing logic is executed through the message queues, and the bank system is called to complete the payment processing. In embodiments of the present invention, each of the one or more message queues handles only one logic. The payment processing includes processing for paying gasoline and gas, refunding guarantee fund, collecting payment, and freezing credit for borrowing, besides the freight fee.
Step 103 specifically includes the following processing:
the method comprises the steps of sequentially calling corresponding message queues according to each processing logic required for completing current payment recorded in a transaction record table, executing the corresponding logic through the message queues, calling a bank system to pay, receiving payment result information fed back by the bank system, feeding the current payment result information back to the payment system, updating execution results of the corresponding processing logic in the transaction record table through the payment system according to the payment result information, and determining a final result according to the execution results of each processing logic after all processing logics are executed.
In addition, when a certain message queue execution processing logic calls the payment system to cause payment failure, the message queue is put again for processing, and if the number of times or time of processing exceeds a preset threshold value, an abnormal state notification is sent out.
Fig. 2 is a schematic diagram of state transition in an order payment process according to an embodiment of the present invention, and as shown in fig. 2, the state transition in the order payment process mainly includes: owner of goods-Ticket Source company-driver. The dashed lines in fig. 2 only identify logical relationships.
As shown in fig. 2, the following takes a batch payment 30 sheet as an example to describe the abnormal situation handling of the embodiment of the present invention:
1. and the service system calls a platform payment interface of the payment system 30 times to complete order payment one time. If the 15 th order payment fails, skipping, continuing to pay the subsequent orders, and finally writing the data of the batch payment 29 list into the batch record table batch _ pay _ info; the specific parameters of batch _ pay _ info are shown in fig. 3, where batch _ no: req _ no as a fund to a branch; sum _ amount: paying the sum in batches; shipper _ id: company _ id in the order record.
2. The platform payment is successful, but the order status update fails. At this point the order is in error, but subsequent orders will continue to pay. When the sum is paid to the branch company, the problem is found, and the subsequent payment process is not carried out;
3. the generated 29 single batch payment data fails to be written into the batch _ pay _ info, and the 29 single batch payment data which is paid by the completed platform is not rolled back and is still completed. At this time, there are 29 records in the order record batch _ path _ order _ info whose status is 40. An exception handling queue can be added to complete the subsequent payment process; specific parameters of batch _ patch _ order _ info are shown in fig. 3, where final _ carrier _ id: if the order is set to collect, the order is a collector, otherwise, the order is a driver; pay _ amount: final _ pay in the order; batch _ seq _ no: the client number, namely the sequence number, in the batch payment file is consistent with the query result return sequence number and is updated when the file is generated; postscript: freight + "+ order _ no; all _ time: calling the bank instruction money-drawing time; write the batch _ pay _ info succeeds, but fails to transfer money to the ticketing company.
And respectively processing according to failure reasons:
(1) the main balance of the goods is insufficient, the marked recorded corresponding to the batch _ pay _ info writes that the main balance of the goods is insufficient, and the payment is finished;
(2) the transaction state is unknown, and the query state of the transaction state query interface is called in a delayed mode. If the result is unknown, remark records the error reason and finishes payment; if the state returns to success, continuing the subsequent payment process;
(3) the processing mode is the same as that of (2) when the 'no information is returned' or the 'network overtime' is caused by the network reason;
(4) other errors are processed in the same manner as (1).
The above technical solutions of the embodiments of the present invention are exemplified by taking payment of a logistics system as an example.
Fig. 4 is a flowchart of detailed processing of a concurrent payment method according to an embodiment of the present invention, and as shown in fig. 4, the concurrent payment method according to the embodiment of the present invention specifically includes:
1. the payment operator checks the order to be paid, and after confirming the information, the data is transmitted to the application background system;
2. and the application background system checks the data validity (for example, whether the password is correct or not, whether the submitted data is real or not and the like), and stores the batch order summary record with the unique batch number into the database, wherein the batch order summary record comprises a character string formed by combining the total amount and the order unique identification id. After the successful storage is ensured, a payment request is sent to a payment system;
3. the payment system receives an order payment request from an external interface, checks data, performs idempotent verification, needs to add a distributed lock after the verification is passed, and starts to record platform transaction details of the order to form a transaction record table, wherein the transaction record table sets a unique index for the order number, so that the platform can ensure that only one order is successfully put in storage in the recording process, and repeated payment is prevented at the level of a database;
4. the first stage of the payment system is platform data processing, and external services such as a bank system and the like are not called, so that the processing speed is high, large batch of order payment can be completed in a short time, the peak payment pressure is relieved, and if the order payment is abnormal, abnormal prompt is carried out;
5. and after the platform data is processed, the payment system returns a payment result which is used as a final processing result. Meanwhile, the subsequent adjustment processing of the bank system is carried out by the message queue and the compensation mechanism together;
6. setting a plurality of message queues, wherein each queue only processes one logic as much as possible, for example, the message queue A is only responsible for transferring accounts from owners to receivers, the message queue B is only responsible for transferring accounts from receivers to other owners, the queues are dynamically increased according to actual conditions, and priorities are set;
7. and the message queue processes the bank system processing state for updating order payment, ensures the final consistency of data, and if the record with uncertain payment result caused by bank service abnormity or other unknown abnormity is encountered, the record needs to be continuously queued or processed by a compensation mechanism.
As can be seen from the above description, the following measures are taken in the embodiments of the present invention to solve the problems in the conventional payment service scenario:
1. the data processing of the payment system platform is separated from the processing of the bank system, and the platform processing result is taken as the standard.
2. The transaction record table in the database sets a unique index for the payment order field to prevent the order from being paid repeatedly.
3. By using batch payment and reasonably setting the upper limit of the quantity, the failed payment order can not influence the payment of other orders in the same batch.
4. Multiple message queues are used, each queue takes its own role, the priority is set according to the actual situation, and the logic sequence processing is ensured.
5. And the compensation mechanism uses a timing task to scan the order which needs to be processed continuously at a timing so as to ensure that the order is processed successfully.
In summary, by means of the technical scheme of the embodiment of the invention, the payment pressure in high concurrency can be relieved, the efficiency of the payment system is improved, and the error rate of payment is reduced.
