[0002] With the development of technology, online transactions are chosen by more and more users due to their convenience. Therefore, the stability and timeliness of online transactions are becoming increasingly important. In related technologies, if an abnormality occurs during the transaction processing of an online transaction system, usually the transaction will be suspended, resulting in the inability to continue processing the transaction and also unable to initiate it again. If you want to continue processing the transaction, you need to wait for the day-end suspense account query or the night batch closure to detect the abnormality and close the transaction.

[0003] In the process of implementing the concept of the present disclosure, the inventors found that there are at least the following problems in related technologies: Since the online transaction system in related technologies suspends the transaction if an abnormality occurs during the transaction processing, it cannot be continuously processed, and the detection of abnormalities is not timely enough, which may cause the transaction to be unable to be processed for a long time, resulting in a long transaction processing time.

[0024] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. However, it should be understood that these descriptions are merely exemplary and are not intended to limit the scope of the present disclosure. In the following detailed description, for the sake of explanation, numerous specific details are set forth in order to provide a comprehensive understanding of the embodiments of the present disclosure. However, it is obvious that one or more embodiments can also be implemented without these specific details. In addition, in the following description, descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present disclosure.

[0025] The terms used herein are merely for describing specific embodiments and are not intended to limit the present disclosure. The terms "including", "comprising", etc. used herein indicate the presence of features, steps, operations, and / or components, but do not exclude the presence or addition of one or more other features, steps, operations, or components.

[0026] All terms used herein (including technical and scientific terms) have the meanings commonly understood by those skilled in the art, unless otherwise defined. It should be noted that the terms used herein should be interpreted as having a meaning consistent with the context of this specification and should not be interpreted in an idealized or overly rigid manner.

[0027] In the case of using expressions such as "at least one of A, B, and C, etc.", generally, it should be interpreted according to the meaning commonly understood by those skilled in the art (for example, "a system having at least one of A, B, and C" should include, but is not limited to, a system having only A, only B, only C, having A and B, having A and C, having B and C, and / or having A, B, and C, etc.).

[0028] It should be noted that the transaction processing method and apparatus of the present disclosure can be used in the fields of fintech and artificial intelligence technologies, and can also be used in any field other than the fintech field or the artificial intelligence technology field, such as: the computer technology field, the data processing technology field, etc. The application fields of the transaction processing method and apparatus of the present disclosure are not limited.

[0029] In the technical solution of the present disclosure, the user information involved (including but not limited to user personal information, user image information, user device information, such as location information, etc.) and data (including but not limited to data for analysis, stored data, displayed data, etc.) are all information and data authorized by the user or fully authorized by all parties. Moreover, the processing of relevant data, such as collection, storage, use, processing, transmission, provision, disclosure, and application, all comply with relevant laws, regulations, and standards, take necessary confidentiality measures, do not violate public order and good customs, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0030] In the scenario of making automated decisions using personal information, the methods, devices, and systems provided by the embodiments of the present disclosure all provide corresponding operation entrances for users to choose to agree or reject the automated decision results; if the user chooses to reject, the expert decision-making process will be entered. The expression "automated decision" here refers to the activity of automatically analyzing and evaluating an individual's behavior habits, hobbies, or economic, health, credit status, etc. through a computer program and making a decision. The expression "expert decision" here refers to the activity of making a decision by a person who specializes in a certain field, has specialized experience, knowledge, and skills, and has reached a certain professional level.

[0031] During the research process, it was found that in online transactions, such as online transfer transactions, in the related art, when an unknown or abnormal situation occurs downstream of the transfer system, the bank-securities transfer system still transmits the unknown status to the securities firm, ultimately resulting in the securities firm obtaining the unknown status of the transaction and affecting the customer's investment behavior.

[0032] If you want to close the above transaction loop, in the related art, it is usually achieved through daytime doubtful account queries or through batch processing at night. However, these methods are all post-processing and may still result in a relatively long transaction processing time and reduce customer satisfaction.

Correspondingly, the transaction processing device provided by the embodiments of the present disclosure can also be set in a server or a server cluster different from the server 105 and capable of communicating with the first terminal device 101, the second terminal device 102, the third terminal device 103, and / or the server 105.

[0040] It should be understood that Figure 1 the numbers of terminal devices, networks, and servers in are merely illustrative. According to actual needs, there can be any number of terminal devices, networks, and servers.

[0041] Based on the scenario described below, the transaction processing method of the disclosed embodiments will be described in detail through Figure 1 the following. Figures 2 to 4 The transaction processing method of the disclosed embodiments will be described in detail through the following.

[0042] Figure 2 FIG. schematically shows a flowchart of a transaction processing method according to an embodiment of the present disclosure.

[0043] As Figure 2 shown, the method includes operations S210 to S240.

[0044] In operation S210, in response to receiving a transaction processing request, an application link for the transaction processing request is determined based on the transaction type included in the transaction processing request, where the application link includes dependencies between multiple applications, and the applications include multiple processing containers.

[0045] In operation S220, a health check is performed on the application link based on transaction test data corresponding to the transaction type and dependencies, and address information of available containers of each of the multiple applications is obtained, where the available containers are determined from the multiple processing containers.

[0046] In operation S230, the address information of the available containers of each of the multiple applications is associated with the transaction processing request to obtain associated data.

[0047] In operation S240, the associated data and the transaction processing request are sent to the starting application in the application link, where the starting application transmits the associated data and the transaction processing request in the application link, and the associated data is used to enable each application in the application link to process the transaction processing request based on the target container, and the address information of the target container is the same as the address information of the available container corresponding to the application.

[0048] According to an embodiment of the present disclosure, the transaction processing method may be executed by a pre-check component, and the pre-check component may be used to receive a transaction processing request and communicate with the starting application in the application link.

[0049] According to an embodiment of the present disclosure, the transaction processing request may be sent by a client that initiates a transaction.

[0050] According to an embodiment of the present disclosure, the type of the transaction is not limited and may be a transfer type, a loan type, a deposit and withdrawal type, etc.

[0051] According to an embodiment of the present disclosure, the transaction processing request may include: a transaction type, a transaction amount, a transaction identifier, etc.

[0052] According to an embodiment of the present disclosure, the application may be an application program, an application server, etc. The processing container is a container for processing transaction processing requests.

[0053] According to an embodiment of the present disclosure, the address information of the available container may include: container identifier, network protocol address, container port, etc.

[0054] According to an embodiment of the present disclosure, based on the transaction type, an application link for the transaction processing request may be determined from at least one preset application link for processing the transaction type.

[0055] According to an embodiment of the present disclosure, by transmitting transaction test data among multiple applications and performing health checks on the multiple applications respectively, the transmission order may be determined by the dependency relationship.

[0056] According to an embodiment of the present disclosure, there is no limitation on the manner of associating the address information of the available container and the transaction processing request, and it may be achieved by concatenating the identifier of each application, the address information of the available container of each application, and the transaction identifier in the transaction processing request.

[0057] According to an embodiment of the present disclosure, by sending the association data and the transaction processing request to the starting application, the starting application transmits the association data and the transaction processing request in the application link, so that each application determines the target container for processing the transaction processing request through the address information of the available container included in the association data.

[0058] According to an embodiment of the present disclosure, the transmission order of the association data and the transaction processing request in the application link is determined based on the dependency relationship.

[0059] According to an embodiment of the present disclosure, by performing a health check on the application link before processing the customer's transaction processing request, that is, detecting in advance whether the processing link is normal, the occurrence data of unknown transactions is reduced, and the occurrence of customer complaints is reduced.

[0060] According to an embodiment of the present disclosure, before processing a transaction processing request of a customer, an application link for processing the transaction processing request is determined, and a health check is performed on each available container in the application link based on the dependency relationship between multiple applications in the application link and transaction test data corresponding to the transaction type, so as to determine the address information of the healthy available containers in each application, and associate the address information of each available container with the transaction processing request, so that when each application in the application link processes the transaction processing request, the above-mentioned available containers can be used for processing. Since the address information of the available containers of each application in the application link is determined and associated with the transaction processing request, each application in the application link can use the above-mentioned available containers for processing when processing the transaction processing request, thereby reducing the probability of transaction suspension and abnormal transaction caused by abnormal transaction processing, and at least partially solving the technical problem of long transaction processing time in the related art, and achieving the technical effect of improving the transaction success rate and customer satisfaction.

[0061] According to an embodiment of the present disclosure, based on the transaction test data corresponding to the transaction type and the dependency relationship, a health check is performed on the application link to obtain the address information of the available containers of each of the multiple applications, which may include the following operations.

[0062] Based on the dependency relationship, determine the transfer order of the transaction test data among the multiple applications; based on the transfer order and the transaction test data, perform health checks on the processing containers of each of the multiple applications and the databases of each of the multiple applications respectively to obtain the health check results of each of the multiple applications; determine the address information of the healthy containers included in the health check results of each of the multiple applications as the address information of the available containers corresponding to each of the multiple applications.

[0063] According to an embodiment of the present disclosure, the dependency relationship between multiple applications can be analyzed, and a directed graph is constructed through the dependency relationship, where the nodes in the directed graph are applications, and the edges of the directed graph represent the dependency relationship, so as to determine the transfer order through the node positions in the directed graph.

[0064] According to an embodiment of the present disclosure, when performing a health check on an application, a health check can be performed on the database of the application and the processing containers included in the application respectively. When it is determined that the database of the application is in a healthy state and there are available containers (i.e., containers in a healthy state) in the processing containers, it is determined that the application is in a healthy state.

[0065] According to an embodiment of the present disclosure, the health check result of an application may include the address information of the processing containers in a healthy state, i.e., healthy containers, and determine this address information as the address information of the available containers.

[0066] According to an embodiment of the present disclosure, by relying on the dependency relationship, a reasonable transfer order of transaction test data among multiple applications is determined, and the health checks of the processing containers and databases of each of the multiple applications are sequentially performed according to the transfer order, thereby improving the inspection efficiency of the health check.

[0067] According to an embodiment of the present disclosure, the transaction test data includes: database detection sub-data and container detection sub-data; based on the transfer order and the transaction test data, the health checks of the processing containers and databases of each of the multiple applications are sequentially performed respectively to obtain the health check results of each of the multiple applications, which may include the following operations.

[0068] Based on the transfer order and the database detection sub-data, the health checks of the databases of each of the multiple applications are sequentially performed to obtain the database check results of each of the multiple applications; in the case where the database check results of each of the multiple applications all indicate health, based on the container detection sub-data and the transfer order, the health checks of the processing containers of each of the multiple applications are sequentially performed to obtain the health check results of the target application.

[0069] According to an embodiment of the present disclosure, the database detection sub-data may include instructions for performing a health check on the database. The instructions may include database access instructions, database write instructions, and database read instructions.

[0070] According to an embodiment of the present disclosure, in the case where it is recognized through the above instructions that the database can be normally accessed and the database response duration is not greater than a first preset duration, it is determined that the database is in a healthy state, that is, the database health check result of the database indicates health, where the first preset duration is not limited and can be set according to the actual situation.

[0071] According to an embodiment of the present disclosure, in the case where the database check results of each of the multiple applications all indicate health, the health checks of the processing containers of each of the multiple applications are sequentially performed to determine whether there are available containers for each application.

[0072] According to an embodiment of the present disclosure, since the health check speed of the database is relatively fast, by first sequentially performing the health checks of the databases of multiple applications based on the transfer order and then sequentially performing the health checks of the processing containers of multiple applications when the health checks of the databases of multiple applications all pass, the technical effect of improving the health check speed can be achieved.

[0073] According to an embodiment of the present disclosure, the container detection sub-data includes: health check instructions and test transaction requests corresponding to multiple applications respectively; the health check instructions are used to perform health checks on multiple processing containers included in the application; based on the container detection sub-data and the transfer order, health checks are sequentially performed on the processing containers of multiple applications to obtain the health check results of the target application, which may include the following operations.

[0074] Send the container detection sub-data and the transfer order to the starting application in the application link; receive the health check results of multiple applications returned by the starting application; wherein, the starting application is used to perform the following operations.

[0075] Based on the health check instructions and test transaction requests corresponding to the starting application, perform a health check on multiple processing containers of the starting application to obtain the first health check result of the starting application; in the case where the first health check result indicates that there are available containers in the starting application, delete the health check instructions and test transaction requests corresponding to the starting application in the container detection sub-data to obtain new container detection sub-data; based on the transfer order, send the processing data of the available containers for the test transaction request, the transfer order, and the new container detection sub-data to the downstream application of the starting application, wherein the downstream application is used to perform a health check on multiple processing containers included in the downstream application through the health check instructions and processing data corresponding to the downstream application to obtain the second health check result, and is used to transfer the second health check result to the starting application in the case where the downstream application is determined to be the end application based on the transfer order; in the case where it is determined that the health check result of the end application is received, summarize and forward the first health check result and the second health check result.

[0076] According to an embodiment of the present disclosure, each application may include a health check container for executing the health check instructions, and the health check instructions corresponding to each application may be used to instruct the health check container to perform a health check on multiple processing containers.

[0077] According to an embodiment of the present disclosure, the downstream application is an application downstream of the starting application.

[0078] According to an embodiment of the present disclosure, for each application, when it is determined that there are multiple healthy applications, one with the best performance may be determined through load balancing.

[0079] According to an embodiment of the present disclosure, the health check of multiple processing containers may include: checking whether each processing container can process the input data normally and obtain the correct processing result. It may also include: checking whether the duration for each processing container to obtain the processing result is less than a second preset duration, and in the case where it is less than the second preset duration, considering the processing container as a healthy container.

[0080] According to an embodiment of the present disclosure, the test transaction request is a preset transaction request that matches the transaction type, and the test transaction request may include correct processing results of respective processing containers of multiple applications during the process of processing input data.

[0081] According to an embodiment of the present disclosure, the input data of the respective processing containers of each application may be based on the output data of the application upstream of the application. For example, if the input data of the starting application is the test transaction request, then the input data of the downstream application of the starting application is the processed data obtained by the available containers in the starting application for processing the test transaction request.

[0082] According to an embodiment of the present disclosure, the starting application is the application located in the first position in the transfer order, and the end application is the application located in the last position in the transfer order.

[0083] According to an embodiment of the present disclosure, when it is determined based on the transfer order that the downstream application is not the end application and the second health result indicates that there are available containers in the downstream application, the downstream application may repeat the operation steps of the starting application. For example, delete the health check instruction in the new container detection sub-data that matches the downstream application to obtain updated container detection sub-data, and send the updated container detection sub-data, the new processing data of the available containers in the downstream application for the processing data, and the transfer order to the more downstream application of the downstream application.

[0084] According to an embodiment of the present disclosure, the more downstream application repeats the operation of the downstream application: for example, the more downstream application executes the health check instruction and obtains a third health check result. And when it is determined based on the transfer order that the downstream application is the end application, send the third health check result to the downstream application.

[0085] According to an embodiment of the present disclosure, when the downstream application is not the end application, continue with the health check of the next application until the end application is reached.

[0086] According to an embodiment of the present disclosure, the transmission of the health detection results may be in the reverse order of the transfer order.

[0087] According to an embodiment of the present disclosure, after receiving the health check result sent by the application downstream, the application upstream packages the health check result sent by the application downstream and its own health check result together into a data packet and sends it to the more upstream application.

[0088] According to an embodiment of the present disclosure, after receiving the health check results of all applications, the starting application summarizes them and forwards them to the pre-check component.

[0089] According to an embodiment of the present disclosure, when the health check result of the upstream application indicates that there are no available containers, it is possible not to continue the health check of the downstream application, but to quickly determine a new application link for health check and process the transaction processing request, thereby saving the transaction processing time.

[0090] According to an embodiment of the present disclosure, for example: if the first health check result indicates that there are no available containers in the starting application, an error message can be generated based on the first health detection result, and the health check of the downstream application can be stopped.

[0091] According to an embodiment of the present disclosure, during the health check, by sending the container detection sub-data to the starting application in the application link and passing the health check instructions downward in the transfer order, automated health check is achieved. And the downstream application reversely transfers its own health check result to the upstream application through this transfer order and finally aggregates it into the starting application, which is then sent to the pre-check component by the starting application after aggregation, achieving the saving of communication resources.

[0092] Figure 3 A schematic diagram of the pre-check component and the application link according to an embodiment of the present disclosure is schematically shown.

[0093] As Figure 3 shown, in some embodiments, the application link includes the following three applications: Application 1, Application 2, and Application 3. And each application respectively includes an access layer and a service layer. The access layer and the service layer respectively include a plurality of processing containers. Among them, Application 1 is the starting application, Application 2 is the downstream application of the starting application, and Application 3 is the downstream application of the downstream application, that is, the further downstream application, and it is the end application.

[0094] According to an embodiment of the present disclosure, when performing the health check of the application link, the pre-check component sends a check data packet including the container detection sub-data and the transfer order to Application 1. Application 1 performs health checks on the multiple processing containers included in the access layer and the service layer respectively through the container detection sub-data to obtain the first health check result. Among them, the processing data of the available containers in the access layer will be passed into the service layer so that the processing containers in the service layer can perform health checks.

[0095] According to an embodiment of the present disclosure, when the first health check result indicates that there are available containers in both the access layer and the service layer of Application 1, Application 1 deletes the health check instructions and test transaction requests corresponding to Application 1 in the container detection sub-data to obtain new container detection sub-data. And based on the transfer order, it sends the processing data of the available containers in the service layer of Application 1, the transfer order, and the new container detection sub-data to Application 2.

[0096] According to an embodiment of the present disclosure, Application 2 performs a health check on multiple processing containers included in the access layer and the service layer of Application 2 based on the health check instructions and processing data corresponding to Application 2, and obtains a second health check result. When the second health check result indicates that there are available containers in both the access layer and the service layer of Application 1, Application 2 deletes the health check instructions corresponding to Application 2 in the new container detection sub-data to obtain updated container detection sub-data. And based on the transfer order, it sends the processing data, transfer order, and updated container detection sub-data of the available containers in the service layer of Application 2 to Application 3.

[0097] According to an embodiment of the present disclosure, Application 3 performs a health check on multiple processing containers included in the access layer and the service layer of Application 2 based on the health check instructions and processing data corresponding to Application 2, and obtains a third health check result.

[0098] According to an embodiment of the present disclosure, Application 3 sends the third inspection result to Application 2. After receiving the third health check result, Application 2 packages the second health check result and the third health check result into a data packet and sends it to Application 1. After receiving the data packet, Application 1 packages the first health check result, the second health check result, and the third health check result into a result data packet and sends it to the pre-inspection component.

[0099] According to an embodiment of the present disclosure, the pre-inspection component associates the address information of the available containers in the access layer and the service layer of Application 1, the address information of the available containers in the access layer and the service layer of Application 2, and the address information of the available containers in the access layer and the service layer of Application 3 included in the first health check result, the second health check result, and the third health check result respectively with the transaction processing request to obtain associated data.

[0100] According to an embodiment of the present disclosure, the pre-inspection component packages the associated data and the transaction processing request into a first actual transaction data packet and sends it to Application 1.

[0101] According to an embodiment of the present disclosure, the transaction processing method may further include the following operations.

[0102] In response to an abnormal situation occurring during the processing of the transaction processing request by an application in the application link, query the target data matching the transaction processing request in the databases of the multiple applications respectively to obtain query results for the databases of the multiple applications; for the query results of each application's database, when the query result indicates that there is target data in the database that matches the transaction processing request, update the data status of the target data to processing failed.

[0103] According to an embodiment of the present disclosure, not limiting abnormal situations may include: not receiving a final processing result for the transaction processing request within a third preset duration, receiving an error message from any application in the application link, etc. The third preset duration is not limited and can be set according to actual situations.

[0104] According to an embodiment of the present disclosure, the final processing result and the error message may be sent by the starting application to the pre-check component after being reversely transmitted to the starting application. It may also be sent by the application that outputs the above information to the pre-check component.

[0105] According to an embodiment of the present disclosure, the transaction identifier of the transaction processing request may be queried in the database to obtain target data matching the transaction processing request.

[0106] According to an embodiment of the present disclosure, by updating the data status of the target data to processing failure, a fast closed-loop of the transaction can be achieved, so that the transaction processing request can be initiated again, thereby improving the processing speed of the transaction to a certain extent.

[0107] According to an embodiment of the present disclosure, the transaction processing method may further include the following operations.

[0108] In the case where the query result indicates that there is no target data matching the transaction processing request in the database, preset data matching the transaction processing request is written into the database, where the data status of the preset data is processing failure.

[0109] According to an embodiment of the present disclosure, the specific content of the preset data is not limited and can be set according to actual situations.

[0110] According to an embodiment of the present disclosure, if no target data related to the transaction processing request can be queried in the database, in the available container where the data related to the transaction processing request may be applied, by writing preset data with a data status of processing failure, a fast closed-loop of the transaction can be achieved, facilitating the re-initiation of the transaction processing request.

[0111] According to an embodiment of the present disclosure, determining an application link for the transaction processing request based on the transaction type included in the transaction processing request may include the following operations.

[0112] Based on the transaction type included in the transaction processing request, determine multiple candidate application links from the historical application links of multiple historical transaction processing requests; based on the transaction processing scores of the candidate application links, determine the application link for the transaction processing request from the multiple candidate application links.

[0113] According to an embodiment of the present disclosure, by matching the transaction type with the historical transaction types included in multiple historical transaction processing requests, a target historical transaction processing request with the same historical transaction type as the transaction type can be determined, and the historical application link used to process the target historical transaction processing request can be determined as the candidate application link.

[0114] According to an embodiment of the present disclosure, the application link can be determined according to the transaction processing scores of each candidate application link.

[0115] According to an embodiment of the present disclosure, the transaction processing score can be obtained by comprehensively evaluating various information such as the total transaction processing duration, whether there are abnormal situations during the transaction processing, and user feedback information for the candidate application link.

[0116] According to an embodiment of the present disclosure, the transaction processing scores of multiple candidate application links can be performed, and the candidate application link with the highest transaction processing score can be determined as the application link for processing the current transaction processing request, thereby increasing the passing probability of the health check of the application link and thus increasing the transaction processing success rate.

[0123] In operation S405, it is determined whether an abnormal situation occurs during the processing of the transaction processing request by the application in the application link. In response to the occurrence of an abnormal situation, operation S406 is executed. In response to the non-occurrence of an abnormal situation, operation S410 is executed.

[0124] In operation S406, target data matching the transaction processing request is queried in the respective databases of multiple applications, and query results for the respective databases of multiple applications are obtained.

[0125] In operation S407, it is determined whether the target data is queried. In the case where the target data is queried, operation S408 is executed. In the case where the target data is not queried, operation S409 is executed.

[0126] In operation S408, the data status of the target data is updated to processing failure, and operation S401 is returned.
