Detailed Implementation

[0017] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of the present invention.

[0018] It should be noted that the acquisition, transmission, storage, use, and processing of data in the technical solution of this application all comply with relevant laws and regulations. In the embodiments of this application, certain existing industry solutions such as software, components, and models may be mentioned. These should be considered exemplary, intended only to illustrate the feasibility of implementing the technical solution of this application, and do not imply that the applicant has already used or necessarily used such solutions.

[0019] The data processing method provided in this application can be applied to, for example... Figure 1 In the application environment shown, mobile terminal 102 communicates with server 104 via a network, in a scenario such as... Figure 1 In the application environment shown, the mobile terminal 102 can be, but is not limited to, various personal computers, laptops, smartphones, tablets and portable wearable devices; the server 104 can be implemented using a standalone server or a server cluster consisting of multiple servers.

[0020] In one embodiment, such as Figure 2 As shown, a data processing method is provided, the method including: S202, construct the mapping relationship between each scenario identifier and the query behavior control parameters under the corresponding download scenario to generate full configuration; the query behavior control parameters include at least query template, parameter rules and routing information.

[0021] Full configuration refers to the configuration set of all download scenarios in the system, including all available and configured download scenarios. Download scenarios are defined based on different business needs, data types, etc., and have specific download behaviors and requirements. These can include scenarios such as project statistics, transaction detail statements, transaction screening results, and financial statement export. Different download scenarios will have different query behavior control parameters. The parameter rules for query templates can be configured according to the actual situation. Query behavior control parameters are predefined rules used to control how database queries are generated and executed. These include at least query templates, parameter rules, and routing information, representing the data content, execution method, and data source of the query, etc. They may also include control rules to limit resource usage, control the output format of results, etc. It should be understood that query behavior control parameters are a centralized management of query logic and rules, and the relationship between various configurations can be modified according to the actual application situation.

[0022] A query template is a file of SQL statements that provides the data structure and basic logic for queries. It can be replaced, concatenated, and deleted based on parameter matching rules. Parameter rules define the handling rules for wildcards in the template and can be divided into two categories: required parameter rules and optional parameter rules. Required parameters are the specific values ​​that users must provide in the actual download conditions, corresponding to the required fields in the query template, forming complete query conditions. For example, in a report download scenario, fields such as time, organization, and employee can be set as required fields. Routing information refers to the storage location information of the target data. When data is stored in a microservice or sharded database architecture, it ensures that subsequent queries can be routed to the correct database cluster, database, and table.

[0023] S204, in response to receiving a download service request, retrieves the corresponding target query template, target parameter rules, and target routing information from the full configuration based on the scenario identifier carried in the download service request; based on the target parameter rules, concatenates the download conditions carried in the download service request into the target query template; and based on the target routing information and the updated target query template, generates a data object for asynchronous download.

[0024] A download request is a user-initiated request object requesting the execution of an asynchronous download operation. It contains all the information needed to complete the operation, including a scenario identifier, download conditions, request timestamp, user information, etc. The scenario identifier carried in the download request is a unique identifier for each download scenario, used to match pre-configured download scenarios. When the user requests, this identifier is used to locate the corresponding configuration set; it can be a string identifier, such as "user_export" or "jfmx". Download conditions contain a set of various parameters set by the user for this download. After validation, these parameters will replace wildcards in the query template to satisfy the user's query requirements. The data object is a structured object output by the parameter concatenation service, containing all the information needed to execute the asynchronous download, and can include a complete SQL query statement and corresponding routing information.

[0025] In this embodiment, the download scenario and processing logic are separated, which enables a standardized data processing flow and improves the efficiency of development and operation. At the same time, this combined splicing service can be reused in multiple scenarios. In practical applications, only the corresponding configuration file parameter matching rules or the design of necessary parameters need to be modified according to business requirements, which is highly flexible and scalable.

[0026] In one embodiment, the full configuration update step includes: creating a new query template corresponding to the new download scenario; defining corresponding parameter rules according to the query template; configuring corresponding routing information according to the data source of the query template; if the routing information is verified, establishing a mapping relationship between the scenario identifier, query template, parameter rules and routing information under the new download scenario; adding the mapping relationship to the full configuration to generate a new full configuration.

[0027] In this embodiment, each scenario identifier in the full configuration has a corresponding file storage path. Query templates can be created under this path. The template content can inherit from the base template or be written with SQL statements according to specific application scenarios. Furthermore, necessary parameter rules and optional parameter rules are defined to determine the necessary options passed by the user. Constraints such as parameter data type, format, and enumeration values ​​must be defined. Necessary parameters must completely match wildcards in the template. Users can add optional parameters, and default values ​​can be set for optional parameters. To associate scenario identifiers with physical data sources, routing information is configured based on parameters. This verifies data consistency and routing connectivity, checks whether the fields in the query template match the actual table structure of the data source, and checks whether the parameter rules cover all necessary fields. By simulating request parameter instances, the routing logic is tested to ensure it can correctly parse the target data source. The data verification process can be automated. Finally, the verified configuration information is written to the scenario list as serialized structured data, which can be stored in key-value pairs. When a new download scenario needs to be added, only the new configuration needs to be added according to the standard format, without modifying any code logic. Furthermore, to further improve flexibility and scalability, template inheritance can be configured, allowing new download scenarios to inherit and override the base template configuration.

[0028] In one embodiment, the target parameter rules include necessary parameter rules; the step of concatenating the download conditions carried in the download service request into the target query template based on the target parameter rules includes: obtaining the necessary parameters in the download conditions; traversing the necessary list in the query template and checking whether the necessary parameters are missing; and replacing the necessary parameters in the corresponding positions in the target query template if the necessary parameters are complete.

[0029] Based on the target parameter rules, the download conditions carried in the download service request are appended to the target query template. The download conditions must include at least the necessary parameters, and these parameters replace the necessary fields in the target query template. For each necessary parameter, the system checks if the user-provided parameter has a corresponding key-value pair in the target query template, and replaces the placeholder with the actual value of the provided necessary parameter. It should be understood that the download conditions need to be parsed when appending them to the target query template; if any necessary parameters are empty or incomplete, an error message is returned.

[0030] In one embodiment, the target parameter rule includes the maximum download volume; the step of concatenating the download conditions carried in the download service request into the target query template based on the target parameter rule includes: reading the number of query records in the download conditions; if the reading is successful, using the number of query records as the final download volume of the target query template; if the reading fails, using the preset download volume in the target query template as the final download volume; if the preset download volume is empty, using the maximum download volume in the download scenario as the final download volume.

[0031] In this embodiment, the maximum download volume refers to the maximum number of data rows allowed to be downloaded in this scenario. Query limits can be set according to the download scenario to ensure query time. The download conditions carried in the download service request are parsed, and the number of query rows in the download conditions is read. For example, maxRows=30000. If the parameter exists and meets the parameter rules, it is marked as successfully read, and this value is used as the final download volume. If the user does not specify the number of query rows or the number of query rows is invalid, the preset download volume is read from the query template of the current scenario. If the preset download volume exists and is valid, it is used as the final download volume. If the query template of the current scenario does not define a preset download volume, the default maximum download volume of the download scenario is obtained from the configuration as the final download volume. This setting is to ensure that the system can meet user customization needs while taking into account configuration robustness and avoiding invalid query rows being entered into the query template.

[0032] In one embodiment, the target parameter rule includes optional parameter rules; the step of concatenating the download conditions carried in the download service request into the target query template based on the target parameter rules includes: obtaining optional parameters in the download conditions; traversing the optional list in the query template and generating the intersection of the list and the optional parameters; and replacing each optional parameter in the intersection with the corresponding position in the target query template.

[0033] In this embodiment, download conditions are parsed, and optional parameters are extracted. If no optional parameters are explicitly specified, they are left empty by default, and no optional filtering conditions are enabled. The display of optional parameters follows the default configuration. The wildcard list defining optional parameters in the query template is traversed, and the names of the optional parameters and their positions in the template are recorded. The intersection of the optional parameter list in the query template and the set of optional parameters in the download conditions is taken. For each parameter in the intersection, its value is replaced with the corresponding wildcard position in the template. This method allows users to filter data as needed without modifying the template.

[0034] In one embodiment, the target parameter rule includes hidden fields; obtaining hidden field identifiers in the query template and download conditions; finding the statement position information corresponding to the hidden field identifier in the query template; and removing the corresponding query statement in the query template based on the statement position information.

[0035] In this embodiment, hidden field identifiers refer to field names that should not appear in the final download results during the query process, such as passwords, personal IDs, and phone information. For data security or privacy protection purposes, these fields need to be removed from the query results. The metadata of the query template is parsed to extract the list of hidden field identifiers. If the download conditions contain hidden field identifiers, they are read and merged into the hidden field list. The syntax fragments corresponding to the hidden fields in the query template are located sequentially, and the syntax fragments corresponding to the hidden fields are deleted or replaced from the query template. The query statement is then reconstructed. Each scenario's query template is configured with a default hidden identifier. This method combines configuration and dynamic processing to ensure data security while providing user flexibility.

[0036] In one embodiment, such as Figure 3 As shown, the download service request also includes user information. Before the step of obtaining the corresponding target query template, target parameter rules, and target routing information from the full configuration based on the scenario identifier carried in the download service request, the process includes: querying whether the download service request carries authentication information; if it is determined that it carries authentication information, querying the permission data of the download service request based on the scenario identifier and user information; comparing the authentication information carried by the user with the permission data and generating a verification result; if the verification result indicates that the verification is successful, continuing to execute the subsequent steps.

[0037] In this embodiment, user information refers to the identity and attribute information of the user initiating the download request, while authentication information refers to the parameters carried in the user request to prove their right to access data. Different download scenarios may require different authentication information, such as customer element information, mobile phone number, key verification fields, etc. To ensure the security of data information within the user's access scope and prevent unauthorized data export, authentication information needs to be extracted from the request header or request body of the download request. If no authentication information is carried, a permission failure error message is returned. If authentication information is carried, the corresponding scenario configuration is located in the full configuration based on the scenario identifier to query the permission rules under that scenario. Combining the user information and permission rules, the user's permission data is generated, and the validity of the authentication information is verified. If the authentication information is valid, the authentication information carried by the user is strongly validated against the permission data, and a validation result is generated. If the validation is successful, the query template for the corresponding scenario in the full configuration is obtained based on the scenario identifier; if the validation fails, a failure message is returned.

[0038] In one embodiment, such as Figure 4 As shown, this application also provides a data processing apparatus 400, the apparatus comprising: The full configuration module 401 is used to construct the mapping relationship between each scenario identifier and the query behavior control parameters under the corresponding download scenario in order to generate the full configuration; the query behavior control parameters include at least the query template, parameter rules and routing information.

[0039] The parameter concatenation module 402 is used to respond to a received download service request, obtain the corresponding target query template, target parameter rules and target routing information from the full configuration according to the scenario identifier carried in the download service request, concatenate the download conditions carried in the download service request into the target query template based on the target parameter rules, and generate a data object for asynchronous download based on the target routing information and the updated target query template.

[0040] In one embodiment, the device further includes a scene update module, which is used to create a query template corresponding to a new download scene; define corresponding parameter rules according to the query template; configure corresponding routing information according to the data source of the query template; and, if the verification of the routing information passes, establish a mapping relationship between the scene identifier, query template, parameter rules and routing information under the new download scene; add the mapping relationship to the full configuration, and generate a new full configuration.

[0041] In one embodiment, the target parameter rules include necessary parameter rules; the parameter concatenation module 402 includes a necessary parameter module, used to obtain necessary parameters in the download conditions; traverse the necessary list in the query template and check whether any necessary parameters are missing; if all necessary parameters are passed in, replace the necessary parameters in the corresponding positions in the target query template. In one embodiment, the target parameter rule includes the maximum download volume; the parameter splicing module 402 also includes a download restriction module, which is used to read the number of query records in the download conditions; if the reading is successful, the number of query records is used as the final download volume of the target query template; if the reading fails, the preset download volume in the target query template is used as the final download volume; if the preset download volume is empty, the maximum download volume in the download scenario is used as the final download volume.

[0042] In one embodiment, the target parameter rule includes optional parameter rules; the parameter splicing module 402 further includes an optional parameter module for obtaining optional parameters in the download conditions; traversing the optional list in the query template and generating the intersection of the list and the optional parameters; and replacing each optional parameter in the intersection with the corresponding position in the target query template.

[0044] In one embodiment, the download service request also includes user information; the parameter splicing module 402 includes a security verification module, used to query whether the download service request carries authentication information; if it is determined that it carries authentication information, the permission data of the download service request is queried according to the scenario identifier and user information; the authentication information carried by the user is compared with the permission data, and a verification result is generated; if the verification result indicates that the verification is passed, the subsequent steps are continued.
