6) And returning the transaction result to the terminal POS, namely, realizing asynchronous communication between the terminal POS machine and the server.
Referring to fig. 2, fig. 2 is a flow chart of a transaction information processing method according to an embodiment of the present application. As shown in fig. 2, the method includes the following steps S21 to S26:
s21, based on a preset rear-end access layer, receiving a transaction request sent by the terminal.
Specifically, in this embodiment of the present application, a back-end service layer (i.e., a preset back-end service layer) is set in the server background, where the back-end service layer is used to process a transaction request of a terminal to obtain a processing node corresponding to the transaction request, and a back-end access layer (i.e., a preset back-end access layer) is set in the server background, where the interaction information between the terminal and the preset back-end service layer is forwarded by the preset back-end access layer, so that the back-end server completes the transaction request of the terminal, and returns a transaction result corresponding to the transaction request to the terminal, so as to implement asynchronous processing of the transaction request of the terminal. Compared with the prior art, the terminal is adopted to directly communicate with the rear-end service layer in the processing of the terminal transaction information, for example, the terminal POS machine is directly communicated with the rear-end service layer, the preset rear-end access layer is added in the background of the server, and the asynchronous communication between the terminal and the rear-end service layer is realized through the preset rear-end access layer, so that the asynchronous transaction between the terminal and the rear-end server is realized, the technical problem that the processing efficiency of the transaction request is lower due to the fact that the processing of the transaction information is limited by the polling interval time and the network communication consumption in the prior art is solved, the processing efficiency of the transaction request is improved, and the experience of a user on the transaction speed is improved. The implementation of this asynchronous transaction is equally applicable to other terminal devices, such as: terminals such as smart phones in smart devices or self-service terminals such as ATM (automatic teller machines) require application scenes in which the terminals and a background server perform instant messaging.
When the terminal carries out the transaction and the background server is required to process the transaction to obtain a transaction result, after the terminal is initialized and connected with the network, the terminal initiates a transaction request to the corresponding background of the background server, and the background server receives the transaction request sent by the terminal based on a preset background access layer.
Further, the preset rear end access layer is constructed by adopting a preset Netty framework. The Netty network communication framework can ensure the performance, stability and scalability of the application, and the Netty network communication framework is used for processing the operations of message transmission, encoding, decoding and the like, so that the processing capacity of service access is ensured.
Further, the step of receiving the transaction request sent by the terminal based on the preset back end access layer includes:
based on the preset rear-end access layer, receiving a transaction request sent by the terminal according to a preset duplex communication mode between the terminal and the preset rear-end access layer.
Specifically, as Netty absorbs various protocols, for example, various protocols including FTP, SMTP, HTTP, TCP and UDP, in order to improve the transmission speed and stability of the terminal and the preset back-end access layer, the terminal and the preset back-end access layer both adopt a duplex communication mode of tcp+protobuff protocol, and simultaneously, the back-end access layer uses a Netty network communication framework to process operations such as transmission, coding, decoding and the like of a message, thereby ensuring the processing capability of service access. Compared with the prior art, the terminal is directly communicated with the rear end service layer, for example, the terminal POS machine is directly communicated with the rear end service layer, and the communication mode adopts simplex communication from the terminal to the rear end.
Further, the preset duplex communication mode includes a duplex communication mode of TCP and ProtoBuff protocol.
Specifically, in the process of implementing terminal transaction asynchronous processing in the embodiment of the application, if the transaction asynchronization adopts a communication protocol of TCP+ProtoBuff, the transmission efficiency and stability of the transaction request can be effectively improved, and the method has great advantages in transmission speed and stability compared with the traditional http/https mode especially in the weak network environment.
S22, forwarding the transaction request to a preset back-end service layer so that the preset back-end service layer processes the transaction request.
S23, subscribing a message notice of the transaction result corresponding to the transaction request to a preset back-end message platform, wherein the message notice is generated by the preset back-end service layer after the transaction request is processed to obtain the transaction result and publishing the transaction result to the preset back-end message platform.
S24, receiving the message notification from the preset back-end message platform.
S25, acquiring a transaction result corresponding to the transaction request according to the message notification.
S26, returning the transaction result to the terminal.
Specifically, after receiving the transaction request of the terminal, the preset back-end access layer forwards the transaction request to a preset back-end service layer, so that the preset back-end service layer processes the transaction request, and meanwhile subscribes a message notification of a transaction result corresponding to the transaction request to a preset back-end message platform, wherein the subscribed content comprises information such as a transaction state, a transaction list number, a transaction amount, payment time, payment mode and the like corresponding to the transaction request. The preset back-end service layer processes the transaction request according to a preset transaction request processing sequence to obtain a transaction result corresponding to the transaction request, wherein the transaction result comprises information such as a transaction state, a transaction bill number, a transaction amount, payment time, payment mode and the like corresponding to the transaction request, and the transaction state comprises transaction success or transaction failure. When the transaction cannot immediately return to the final state, the preset back-end service layer selects a subscription theme and issues a transaction message to the message platform according to a preset strategy of load balancing when the transaction processing is converted to the final state, namely, after the preset back-end service layer finishes processing the transaction request, the obtained transaction result is issued to the preset back-end message platform, and because the preset back-end access layer subscribes a message notification of the transaction result corresponding to the transaction request to the preset back-end message platform, the preset back-end message platform notifies the preset back-end access layer that the transaction result corresponding to the transaction request is generated after receiving the transaction result corresponding to the transaction request, so that the preset back-end access layer obtains the transaction result corresponding to the transaction request from the preset back-end message platform.
The publish-subscribe (Pub/Sub) is a message communication mode, a network structure oriented mode, describes how two different parts of messages are connected and communicated with each other, a sender (Pub) sends the messages, a subscriber (Sub) receives the messages, and a publish/subscribe mechanism is mainly used for constructing instant messaging applications.
And after receiving the message notification of the transaction result corresponding to the transaction request sent by the preset back-end message platform, the preset back-end access layer acquires the transaction result corresponding to the transaction request according to the message notification. According to the method and the device for processing the transaction request, the asynchronous communication between the terminal and the rear-end service layer is achieved through the rear-end access layer and the preset rear-end message platform based on the preset rear-end access layer and the preset rear-end message platform, so that the processing efficiency of the transaction request is improved, and the user experience on the transaction speed is improved.
In the embodiment of the application, based on the preset back-end access layer, the transaction request sent by the terminal is received, and the transaction request is forwarded to the preset back-end service layer, so that the preset back-end service layer processes the transaction request, subscribes to the message notification of the transaction result corresponding to the transaction request from the preset back-end message platform, receives the message notification from the preset back-end message platform, acquires the transaction result corresponding to the transaction request according to the message notification, and returns the transaction result to the terminal, thereby converting instant communication of transaction information between the terminal and the server in the conventional technology into asynchronous communication between the terminal and the server. According to the transaction information processing method for terminal transaction asynchronization, the speed and stability of a transaction result notification touch terminal are improved, meanwhile, the transaction speed and stability are obviously improved when the transaction information processing method is used for carrying out transactions, the merchant can rapidly complete transaction operations such as collection in a business peak period, the terminal service provider is used for analyzing, the service quality of a terminal service product and the acceptance of the market are improved, for example, the terminal POS machine provider is used for analyzing, and the service quality of the terminal POS machine product and the acceptance of the market are improved.
Referring to fig. 3, fig. 3 is a schematic diagram of a first sub-flow of a transaction information processing method according to an embodiment of the present application. In this embodiment, the transaction request includes a preset transaction identifier corresponding to the transaction request, the preset back-end message platform includes a plurality of preset topics, and the step of subscribing the message notification of the transaction result corresponding to the transaction request to the preset back-end message platform includes:
s301, determining a target preset theme corresponding to the transaction request according to the preset transaction identifier;
s302, subscribing the message notification of the transaction result corresponding to the transaction request to the target preset theme.
The Topic is Topic, the messages in the publish-subscribe mode are uniformly collected (i.e. a back-end Message platform is preset), the messages are sent to the Topic by different producers, and are distributed to different subscribers by an MQ server (MQ, english is Message Queue), so that the broadcasting of the messages is realized.
Specifically, in the case that the preset back-end message platform includes a plurality of preset topics, when the topics included in the preset back-end message platform need to be subscribed to the message notification after receiving the transaction request, the subscription of the message notification corresponding to the transaction request needs to be distributed to different preset topics, so that the subscription of the message notification is processed by the plurality of preset topics as uniformly as possible, and the subscription of the message notification adopts a distributed processing mode, so that the processing efficiency of the message notification of the preset topics can be improved, and the network congestion and the bottleneck problem of the performance of computer equipment caused by the processing of a large number of message notifications are relieved. After receiving the transaction request, subscribing the message notification to the theme contained in the preset back-end message platform, various message notification subscription allocation modes can be adopted to allocate the message notification to different preset themes, for example, the message notification subscription in the same preset time period can be allocated to a preset theme, the message notification subscription in another preset time period can be allocated to another preset theme, and the like, the message notification subscription in the same preset time period can also be allocated according to the source of the transaction request, the different preset themes correspond to different transaction request sources, the message notification can also be allocated according to the transaction type to which the transaction request belongs, and the different themes correspond to different transaction types, and the like.
Referring to fig. 4, fig. 4 is a schematic diagram of a second sub-flow of the transaction information processing method according to the embodiment of the present application. In this embodiment, a plurality of preset topics are preset to each corresponding preset topic number, and the step of determining, according to the preset transaction identifier, a target preset topic corresponding to the transaction request includes:
s41, obtaining total topic values of a plurality of topic numbers corresponding to the preset topics;
s42, acquiring the preset transaction identifier, and calculating a transaction identifier Hash value corresponding to the preset transaction identifier according to a preset Hash value calculation mode;
s43, performing modular operation on the total value of the subject based on the Hash value of the transaction identifier to obtain a transaction identifier quotient value corresponding to the preset transaction identifier;
s44, determining a target preset theme number corresponding to the transaction identifier value according to the transaction identifier value and the preset theme number;
s45, determining a target preset theme according to the target preset theme number.
Specifically, in order to improve the processing capability of the preset back-end message platform on the message, the preset back-end message platform may adopt a distributed processing manner, the preset back-end message platform may include a plurality of preset topics, the preset topics are preset with preset topic numbers corresponding to the preset topics, and each topic processes part of the message, for example, the preset back-end message platform may be divided into 4 topics. In order to make a plurality of preset topics balanced and process subscription of message notification, the message notification is distributed to different preset topics, the total topic value of the number corresponding to the preset topics can be obtained by obtaining a plurality of preset transaction identifications corresponding to the transaction requests, meanwhile, the transaction requests comprise preset transaction identifications corresponding to the transaction requests, a preset rear-end access layer obtains the preset transaction identifications after receiving the transaction requests, and calculates a target preset topic number corresponding to the preset transaction identifications according to a preset Hash value calculation mode, because the Hash value is a set of binary values obtained by conducting encryption operation on file contents, each digit in the set of binary values is summed up based on the set of binary values, the value corresponding to the Hash value can be obtained, so that the transaction identifier value corresponding to the preset transaction identifications can be obtained by conducting modular operation on the total topic value based on the transaction identification Hash value, the target preset topic number corresponding to the transaction identifier value is determined according to the transaction identifier value, the target preset topic number corresponding to the preset topic number is calculated, the target preset topic number corresponding to the target preset topic number is calculated, the message processing efficiency can be improved, and the message processing efficiency of the message processing terminals can be improved after the message processing is realized, and the message processing efficiency of the corresponding to the target topic number is improved, the modulus operation (mod) is a principle that the quotient is rounded to the minus infinity direction and is as small as possible when the quotient is calculated, and the modulus operation can be divided into two steps of operation on the assumption that the quotient is an integer a and b:
1) Calculating integer quotient: c=a/b; 2) Calculating a module: r=a- (c×b).
Alternatively, 1) and 2) above can also be described as: 3) And (3) total calculation module: amodb=a-b [ a/b ] ([ a/b ] represents an integer quotient).
Referring to fig. 5, fig. 5 is a schematic diagram of a third sub-flow of the transaction information processing method according to the embodiment of the present application. In this embodiment, before the step of returning the transaction result to the terminal, the method further includes:
s51, judging whether the processing time corresponding to the transaction results is within a preset timeout time, and whether the transaction quantity corresponding to all the transaction results to be processed is smaller than or equal to a preset quantity threshold value;
s52, if the processing time is within the preset timeout time and the transaction quantity corresponding to all the transaction results to be processed is smaller than or equal to a preset quantity threshold, executing the step of returning the transaction results to the terminal;
and S53, if the processing time is not within the preset timeout time or the transaction quantity corresponding to all the transaction results to be processed is greater than the preset quantity threshold, continuously inquiring the transaction results by adopting a polling mechanism.
In particular, considering the timeliness of the transaction, a timeout is generally set for each transaction request, for example, 10 seconds, 15 seconds, or 20 seconds, which is within a time range that the user can afford, and exceeds the timeout, which means that the transaction is not processed immediately. For a transaction request with a relatively high requirement on instantaneity, for example, when a PSO machine is used for carrying out a transaction, a notification message of a transaction result is received by a preset back-end access layer in a very short time, considering the timeliness of the transaction and the stability of the processing capacity corresponding to the preset back-end access layer, the step of returning the transaction result to the terminal is performed at this time, and whether the number of transactions corresponding to the transaction result which is not notified by the preset back-end access layer is within a reasonable range (that is, whether the number of transactions corresponding to all the transaction results to be processed is smaller than or equal to a preset number threshold value) is determined, so that a relatively large pressure is caused to a memory of the preset back-end access layer when the number of the non-notified transactions exceeds the preset specified range, and if the processing time is within the preset timeout time, the number of transactions corresponding to be returned to the terminal is smaller than or if the processing time exceeds the preset timeout time, or if the number of transactions corresponding to be processed is greater than the preset number of transaction results to be processed is greater than the preset timeout time, for example, the asynchronous terminal can be canceled by the asynchronous terminal, and the asynchronous terminal can be guaranteed to wait for the time-by the asynchronous terminal to have a relatively high-quality-of-class communication terminal.
Referring to fig. 6, fig. 6 is a schematic diagram of a fourth sub-flow of the transaction information processing method according to the embodiment of the present application. In this embodiment, the step of returning the transaction result to the terminal comprises:
s61, encrypting the transaction result in a preset encryption mode to obtain a target transaction result.
And S62, returning the target transaction result to the terminal.
Specifically, the transaction result is processed in a preset processing mode, namely original data corresponding to the transaction result is subjected to preset processing, such as assembly, encryption, protoBuff coding and the like, the security in the asynchronous transmission process of the transaction information can be improved through encryption, the ProtoBuff coding mode is used for coding, the information data can be compressed through the ProtoBuff coding, the data quantity of the transaction information data can be reduced, the transmission efficiency of the transaction information data can be further improved, the processed target transaction result is obtained, the data is written through TCP connection held by a Netty frame, the terminal transaction result is notified, the target transaction result is returned to the terminal, for example, in POS transaction, the POS machine terminal is notified of the transaction result of the POS machine, and therefore asynchronous processing of the terminal transaction is achieved.
It should be noted that, the transaction information processing method described in each of the foregoing embodiments may be used to re-combine the technical features included in the different embodiments as needed to obtain a combined implementation, which is within the scope of protection claimed in the present application.
