The task processing system further includes a scheduling center 103, where the scheduling center 103 is configured to periodically trigger an asynchronous task, and notify the task processing device 101 to process a task to be processed in a preset task list, so that the task processing device 101 obtains task information of the task to be processed from the preset task list.
The task processing system further comprises a communication device, wherein the communication device is used for receiving the service request sent by the user terminal and notifying a second application server corresponding to the service request to create the task to be processed corresponding to the service request before the task processing device obtains the task information of the task to be processed.
After receiving the notification of the communication device, the second application server creates a task to be processed corresponding to the service request, and adds the server identifier to task information of the task to be processed.
Specifically, in this embodiment, firstly, a communication device receives a service request sent by a user terminal, and notifies a corresponding second application server to create a task to be processed corresponding to the service request, specifically, the user terminal sends some service requests, the system distributes the service requests to the corresponding second application server, the second application server creates the task to be processed for the service request of the user, in order to solve the problem that the task processing fails due to inconsistent code logic of each application server, when the second application server creates the task to be processed corresponding to the service request, the second server is provided with a processing module (code logic) for processing the task to be processed, and adds own server identification to task information of the task to be processed, and stores the task to be processed and the task information into a preset task table.
Then, the scheduling center 103 periodically triggers an asynchronous task, and notifies the task processing device 103 to process a preset number of tasks to be processed in a preset task table. Such as: 1000 tasks to be processed are scheduled each time. The notification task processing device 103 processes a preset number of tasks to be processed specified in a preset task table.
Further, the task processing device 103 receives task information of the task to be processed transmitted from the scheduling center 103, and then distributes the task in three layers. First, first layer distribution is performed, and task information is distributed to a first application server corresponding to a user identifier based on the user identifier in the task information. And then, carrying out second-layer distribution, and reading corresponding tasks to be processed according to a preset strategy by the first application server based on the distributed task information, generating a task list to be processed, and broadcasting the task list to all application servers. And finally, carrying out third-layer distribution, wherein each application server in the system processes the task to be processed, which is consistent with the self-server identification, in the task list to be processed, and discards the task to be processed, which is inconsistent with the self-server identification. Therefore, the task list to be processed can be broadcast to all application servers, and the application server receiving the task list only processes the task created by the application server and discards other tasks, so that the consistency of logic is ensured, and the success rate of task processing is ensured.
The task processing system in this embodiment may be an account opening service system, and the task to be processed is an account opening task, and specifically, in this embodiment, the task processing process of the task processing system in this embodiment is mainly described in detail in an account opening scenario.
Referring to fig. 2, the task processing system of the present embodiment is applied to an account opening scene. The user terminals 1 and 2 … … n at the user side are all sent to a task processing system (namely an account opening service system) when an account opening request is initiated, and the account opening service system converts the account opening service system into an asynchronous task to control the concurrent quantity of the task and initiate an account opening request service to a financial institution server. The number of the user terminals 1 and 2 … … n can be the centralized account opening requests of a large number of users in the same time period, and the requests can be synchronously received by an account opening service system or can be received in real time in the whole time period. The account opening service system mainly comprises a dispatching center 103 and a task processing device, and is used for processing the account opening requests of the user terminals 1 and 2 … … n, and storing the account opening requests of the user terminals 1 and 2 … … n in a preset task list through asynchronous threads. And then according to the time period configured by the dispatching center 103, periodically triggering asynchronous tasks to call account opening requests stored in a preset task list, and delivering the requests to application servers in the platform layer by a task processing device, so that on one hand, the tasks can be uniformly distributed to all the application servers in the platform for execution, the overall processing capacity of the system is obviously improved, on the other hand, the number of tasks for initiating account opening business to the financial institution server is controlled, and the processing load of the financial institution server is relieved.
First, the communication device receives the account opening request information sent by the user terminal.
The number of the user terminals initiating the account opening request may be thousands, even hundreds of millions, of massive users, and meanwhile, the time of the user terminals initiating the account opening request cannot be estimated accurately, in an embodiment, the account opening request sent by a plurality of user terminals respectively may be received, specifically, a large amount of account opening request information may be received simultaneously or may be received in a centralized manner in a period of time, and in addition, a plurality of account opening request information may be repeatedly initiated in the same user terminal due to factors such as misoperation of the user, network delay or network instability. Such a situation naturally brings about synchronous acceptance and high concurrency processing of massive account opening requests.
At this time, retransmission limitation can be set at the user terminal side through payment APP, when it is monitored that a user initiates multiple account opening requests (such as repeatedly initiating multiple account opening requests) in a short time, information of the account opening requests is limited to be sent outwards, and the page prompts the user to operate too frequently, so that account opening attempts are temporarily delayed. Therefore, the request burden of the financial institution server and the account opening service system applying the method can be reduced, and meanwhile, the problem that some illegal or malicious users cause request congestion paralysis or damage to the system in a flow storm mode is avoided.
Then, the account opening request is distributed to a corresponding second application server, the second application server creates an account opening task aiming at the account opening request, the server identification of the second application server is added to the task information of the account opening task, and the account opening task is stored in a preset task table.
The received account opening request information can be checked first, the validity of the transaction parameters in the account opening request is checked, and the account opening task corresponding to the checked account opening request information is stored in a preset task list.
Further, the verification may include identity verification of the open request information, such as: basic verification checks are performed on information such as the user's identification card number, identification card photograph, passport number, passport photograph, the user's own close-up, bank card number, and/or the year and month of birth. The specific examples are: the number of digits/rule of the identification card number, the number of digits/rule of the passport number, the matching degree of the birth month and the identification card number, the authenticity of the identification card photo/the passport photo is detected by a picture identification means, whether the close-up of the user is a face front picture or not, and the like. Therefore, the system fund risk caused by opening the financial account by the false user is ensured, and further, the information flooding of the false account opening request sent to the financial institution server can be prevented.
Still further, the verification may also include security verification, such as: the necessary data security detection is carried out on the account opening request information so as to prevent tampering through a special field or a reserved extension field in the information, thereby carrying malicious codes and causing great hidden trouble to system security.
The preset task list only stores the account opening task corresponding to the account opening request information passing the verification. Further, the account opening request information which is not checked is discarded, and the corresponding user terminal is informed that the account opening request is not checked, so that the user is requested to verify whether the account opening filling information is accurate again.
In addition, blacklist adding processing can be carried out on the account opening request information which is failed to be repeatedly checked, UIDs and account opening filling information corresponding to the failed account opening request information are extracted and stored in blacklist log information, and meanwhile, a system side issues control information to limit the use of payment APP on the user terminal.
Further, after checking that the account opening task corresponding to the passed account opening request information is stored in the preset task table, the communication device returns a message notification that the user terminal account opening request has been successfully accepted. Therefore, the user can timely acquire whether the account opening request is successfully accepted or not, and the user experience is not reduced due to the fact that the processing time of the financial institution server is uncertain.
And further, storing the account opening task corresponding to the account opening request information into a preset task list through an asynchronous thread. Therefore, a large number of account opening requests of a plurality of user terminals which are possibly sent synchronously are converted into asynchronous tasks and are processed after waiting for subsequent triggering, so that the account opening service applications with centralized time points are orderly and periodically processed in batches, the balance and stability of the task processing load of the whole system are ensured, and the influence on the service burden of a financial institution server is not increased.
Then, the scheduling center 103 periodically triggers the asynchronous task, and extracts the account opening task in the preset task table.
The dispatching center 103 is responsible for periodically triggering asynchronous tasks, and the asynchronous tasks are used for processing account opening tasks stored in a preset task table, so that synchronous acceptance and asynchronous processing of account opening requests are realized.
Further, the asynchronous tasks are triggered periodically according to the CRON expression configured by the dispatch center 103. Specifically, for example, the scheduling center 103 stores a configuration file, and based on a CRON expression in the configuration file, the sending of the asynchronous task trigger message is performed according to a contracted time period. The asynchronous task trigger message is sent to the task processing device 103, and corresponds to the account opening task in the preset task table.
Still further, the number of asynchronous tasks to be periodically transmitted at a time is set by the dispatch center 103 according to a profile. The asynchronous task can be corresponding to the processing of one piece of account opening request information, and can also be corresponding to the processing of a plurality of pieces of account opening request information. The number of asynchronous tasks per transmission may also be set to one piece or a specific number of pieces. And extracting a corresponding number of account opening requests in a preset task list according to configuration requirements in the asynchronous task, and delivering the account opening requests to the task processing device 103 for distribution processing.
The task processing device 103 includes a receiving unit, a first sub-unit, a second distribution unit, and a third distribution unit. Further, according to the expansion of the service scale, the service mode expansion is more diversified, and the like, the task processing device 103 may be expanded to a fourth, fifth, or more layers of processing units, so that each application server in the task processing device 103 is in a state that the task allocation is balanced and the load is stable. Further, the task processing device 103 can be a multi-layered application server cluster.
Taking the above three-layer distribution unit as an example, the first layer is that the task processing device 101 splits the 100 account opening tasks instructed by the dispatch center 103 according to the user identifier. Specifically, the account opening request information is split according to the numerical range of the UID in the account opening task information, and the split account opening request information is distributed to a plurality of application servers according to the UID.
Such as: the user account opening data are respectively stored in 100 tables of 100 databases according to the dimension of the user identification UID and the penultimate three bits. Assuming that the system provides a total of 100 databases of finauth_rz_00-finauth_rz_99, there are a total of 100 task tables corresponding to fa_task_00-fa_task_99. If the user identification 208800000190 of the current user, since the penultimate three bits are 19, the relevant data of the account opening task corresponding to the user is stored in the fa_task_19 table of the finauth_rz_19 database. The user identifiers uid= 2088000001 to 2088000991 corresponding to 100 account opening tasks scheduled by the scheduling center 103 can be split into 100 parts according to the penultimate of UID and three two digits.
Specifically, the account opening task information of the account opening task can be distributed to the designated first application server according to the numerical matching mode. The range of users that each application server can handle is controlled by a unit configuration center, and if the processing range of the application server a is 00, the user identification UID is assigned to the server a with the account opening task information of which the penultimate two digits are 00.
Of course, a random distribution scheme may also be employed. Such as: the method comprises 200 application servers, randomly selecting 100 first application servers, randomly distributing a number of 00-99 for each first application server, and enabling the first application server receiving the number to process an account opening task corresponding to the matched user identification. If the application server B is assigned the numeral 01, it means that the application server B can read the account opening task data with the user identifier uid= 2088000011 from the fa_task_01 table in the finauth_rz_01 database, and perform task processing.
And then a second tier of distribution. The first application server reads the allocated account opening task information, a user identifier, a database for performing task retrieval is determined according to the penultimate three two digits of the user identifier, and the application server can perform account opening task retrieval from the fa_task_03 table of the finauth_rz_03 database on the assumption that the penultimate three two digits of the user identifier of the account opening task information are 03, and a preset number (such as 5, 10 and the like) of account opening tasks can be read each time. And generating an account opening task list aiming at the read account opening task, and broadcasting the account opening task list to all application servers in the whole network. In the specific implementation process, the preset number can be set according to actual needs, and the application is not limited herein.
Before broadcasting, the first application server needs to judge the current environment, if the current environment is an offline development environment, because in the offline development environment, developers can deploy application servers according to service requirements, and the processing functions of each application server are not equivalent. As shown in the schematic fig. 3, if three service branch codes are respectively deployed in three application servers A, B, C, an account opening of an a bank type account with a task ID of 1 is created on three servers A, B, C, an account opening of an a bank type account with a task ID of 2 is queried, an account opening of a B bank type account with a task ID of 3 is randomly allocated when three-layer task is dispatched, if task ID2 is allocated to application server C, task ID3 is allocated to application server a, and the account opening logics of the a bank and the B bank are inconsistent, the processors of application server a and application server C are different, so that the application server a receiving the task and the application server C have no suitable processor to process the task, and the application server creating the task is deployed with a processing program for processing the task. Thus, in an offline development environment, a task needs to be assigned to the application server that created the task. In this embodiment, a distributed broadcasting manner may be adopted to send the task list to a plurality of master nodes, and then each master node broadcasts the task list to a plurality of application servers. And if the current environment is an off-line development environment, the first application server sends the read task list corresponding to the account opening task to all application servers in the whole network.
And finally, carrying out third-layer distribution, if the environment is developed on line, after each application server receives the task list, circularly traversing each task in the task list, judging whether the task is created by the application server or not, namely if the server identification in the task information of the task to be processed in the task list to be processed is consistent with the server identification of the application server, indicating that the task is created by the application server, and acquiring the task data corresponding to the task to be processed. If the task is not created by the user, the task is discarded, and the respective processing of various created tasks is realized through the broadcasting mode.
For the foregoing example in fig. 3, after the system in this embodiment is adopted, please refer to fig. 4, a Host field is added on the basis of the original task model, and is used for recording a server identifier, where the field records which server the current task is created from, and the previous three tasks are packaged into a task list and sent to the master node application server, and then the master node application server can implement broadcasting of the application servers in a corresponding range, so that each application server can obtain a total of 1, 2 and 3 tasks, each server determines whether the Host of the task is consistent with the Host of the current server, if so, processing is performed, otherwise discarding, and executing the task by the server that creates the task is implemented. The method solves the problems that the code streams of different servers are inconsistent, and the received tasks are not processed or the processing logic is incorrect.
If the current environment is not an off-line development environment, the read task can be randomly dispatched to an application server through remote method call, the application server performs different message assembly according to different task types, and the task of opening an account or inquiring the account result is sent to a financial institution server through a gateway.
Further, the account opening result can be returned to the user terminal. The account opening result information can be actively pushed to the corresponding user terminal, or the account opening result is returned to the user terminal after waiting for the user terminal to initiate the account opening result inquiry request. Thus, the situation of unbalanced load of the data flow of the system is effectively avoided.
Fig. 5 is a system flow diagram of the present application to a specific example. As shown in the figure, finsign web is payment APP of the user terminal, finauth is an application server in the account opening service system in the second embodiment, and main responsibilities include: signing the subscription facing to the mechanism; the process service arrangement related to the organization capability in the client authentication, the verification and the subscription request comprises the following steps: mechanism four-element authentication, three-element authentication, mechanism multi-certificate verification capability, mechanism short message verification, mechanism signature-free capability arrangement matching and the like. The account opening service system is composed of a finauth device cluster of a three-layer distribution mechanism. Firstly, a user sends request information for opening an account, such as bank card information, identity information and the like, to an opening service system of a finauth application server cluster of a three-layer distribution mechanism through a finasign web. And checking information validity by the system, and storing the checked account opening request information into a preset task list through an asynchronous thread. In the system, a dispatching center 103 triggers asynchronous tasks at fixed time, a task processing device 103 processes asynchronous account opening tasks, a three-layer distribution mechanism is called to process the asynchronous tasks, account opening requests are packaged into messages, the messages are sent to a bank through a gateway, and the bank can feed back acceptance results.
Further, when receiving the account opening request, the account opening service system converts the account opening request information into an asynchronous task through an asynchronous thread, the asynchronous task comprises parameter information such as a task type, a service ID, a service type, a task state, a task priority, a trigger time, retry times, an end time and the like, and meanwhile, the parameter information in the asynchronous task is converted into a JOSN format and stored in extension information (as shown in fig. 6), so that the task scheduling model can be abstracted into a universal asynchronous task without concerning specific service meanings, when the scheduling center 103 triggers the processing of three-layer tasks, the fished task can find a proper task processor according to the task type to process the service, and the account opening application and the account opening inquiry task are already available in the bank type household items. In the future, more other asynchronous task processors can be expanded according to the service requirement, the task processors are mutually isolated, and the newly added service can not influence the original service. The asynchronous task has good expansion capability.
FIG. 7 is a diagram illustrating an example of a specific asynchronous task schedule for the solution of the present specification. The dispatching center 103 periodically sends a message to a message center according to the configured CRON expression, the message center delivers the message to the finauth application server cluster, and in the first layer of distribution, the task processing device 101 splits the account opening request information according to the UID processing range of the current application deployment unit, and the split account opening request information is distributed to other finauth application servers of the current application deployment unit through remote method call.
