[0054] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0055] In order to solve the technical problems existing in the prior art, the embodiments of the present invention realize that the program computing logic can be changed without hard coding through a configurable manner.

[0056] Figure 1 FIG. 1 is a schematic diagram of the main flow of a method for processing a service request according to an embodiment of the present invention. As an embodiment of the present invention, Figure 1 As shown, the method for processing a service request may include:

[0057] Step 101: receiving a service request from a service system, and parsing the service request to obtain input service parameters.

[0058] The business system calls the dynamic computing service and passes in business parameters. Figure 2 As shown, the dynamic computing service receives a business request from the business system, parses the business request, and obtains input business parameters. The input business parameters include the identifier of the computing script and the identifier of the business data. The business data for computing is obtained from the database through the identifier of the business data, and the computing logic for processing the business data is called through the identifier of the computing script.

[0059] When a business service calls a dynamic calculation service, the input business parameters passed in are JSON objects, so the business system service can configure the data structure (i.e., input attributes) of the input business parameters according to different calculation scripts. The data structure of the input business parameters is as follows:

[0060]

[0061] attrObj can customize the data structure according to different calculation scripts, so as to achieve the purpose of dynamically configuring input business parameters.

[0062] Step 102: Acquire the business data from the database according to the identifier of the business data, and assemble the business data into a result object.

[0063] like Figure 2 As shown, after the dynamic calculation service parses and obtains the input business parameters, it can perform parameter verification, data assembly, calculation script calling, and rendering engine running according to the input business parameters to obtain output business parameters (i.e., calculation results).

[0064] Optionally, obtaining business data from a database according to the identifier of the business data includes: determining whether the identifier of the calculation script is one of the identifiers of the configured calculation scripts; if so, continuing to determine whether the input attribute corresponding to the identifier of the business data matches the identifier of the calculation script; if not, returning an error code and an error message to the business system; if the input attribute corresponding to the identifier of the business data matches the identifier of the calculation script, obtaining business data from a database according to the identifier of the business data; if the input attribute corresponding to the identifier of the business data does not match the identifier of the calculation script, returning an error code and an error message to the business system. In an embodiment of the present invention, each calculation script has its corresponding input attributes, such as an item ID, an item's basic attribute ID, etc. As described in step 101, it is necessary to customize the data structure in advance according to different calculation scripts. Therefore, in step 102, the input business parameters are first checked for regularity, that is, determining whether the input attribute corresponding to the identifier of the business data matches the identifier of the calculation script, such as Figure 3 If the match is successful, the business data is obtained from the database according to the identifier of the business data, and the business data is assembled into a result object. If the match fails, the business processing is terminated, and an error code and error message are returned to the business system, indicating that the input business parameters are incorrect.

[0065] Alternatively, if Figure 4As shown, taking the input business parameter A passed in by business system A as an example, the identifier of the business data includes the item ID and the basic attribute ID of the item. Optionally, the business data is obtained from the database according to the identifier of the business data, and the business data is assembled into a result object, including: obtaining at least one detail line data from the database according to the identifier of the business data, and assembling the at least one detail line data into a result object. The input business parameter only passes the key identifier, and the actual data is still stored in a relational or non-relational database, such as (MySQL, MongoDB, HBASE, etc.); the corresponding detail line data is obtained from the database through the key identifier, and after the data is assembled again, it is passed to the calculation script for calculation.

[0066] Step 103: calling the calculation script according to the identifier of the calculation script.

[0067] Optionally, the calculation script is stored in a directory node of Zookeeper as the node value of the directory node; and the name of the target node is the identifier of the calculation script. Figure 5 As shown, each calculation script is saved in the directory node of Zookeeper (the unique identifier of different calculation scripts is used as the node, or other key values ​​are used as the node). By entering the identifier of the calculation script in the business parameter, the directory node -node in Zookeeper is matched, and the corresponding node value -value (calculation script) is obtained, thereby achieving the purpose of dynamically calling the calculation script.

[0068] Step 104: Obtain output business parameters according to the calculation script and the result object, and return the output business parameters to the business system.

[0069] Alternatively, if Figure 6 As shown, obtaining the output business parameters according to the calculation script and the result object includes: transferring the calculation script and the result object to a rendering engine, and running the rendering engine to obtain the output business parameters.

[0070] When the script calculation is completed, the returned output business parameters are JSON objects. The data structure of the output business parameters (i.e., the returned attributes) can also be configured according to different calculation scripts, thereby achieving the purpose of dynamically configuring the output business parameters. The data structure of the output business parameters is as follows:

[0071] name Fields type Required illustrate Return code code String yes Error message msg String yes result dataJson JSON Object yes Dynamic Results

[0072] Optionally, the rendering engine is Rhino, and the calculation script is a JavaScript calculation script. The embodiment of the present invention transmits the input business parameters and the called calculation script to the Rhino JavaScript rendering engine, and the engine outputs the result JSON object after running, which is then returned to the business system. JavaScript has powerful computing power, custom formulas, custom document conversion rules, and the data type is JSON, which lays a performance advantage for real-time calculation. Therefore, the embodiment of the present invention uses JavaScript as the calculation script.

[0073] When the calculation script is adjusted according to business needs, the data structure of the input and output business parameters is modified, and the node value in Zookeeper (calculation script logic) is also modified. The business system can obtain the corresponding calculation results by calling the dynamic calculation service again, thus achieving the technical effect of zero deployment.

[0074] According to the various embodiments described above, it can be seen that the embodiments of the present invention obtain business data from the database according to the identifier of the business data, assemble the business data into a result object, call the calculation script according to the identifier of the calculation script, and thus obtain the output business parameters according to the calculation script and the result object. The technical problem that hard coding is required to change the program logic in the prior art. The embodiments of the present invention pass parameters through the business system and match the corresponding calculation script for dynamic calculation. Therefore, there is no need to modify the source code of the dynamic calculation service, and there is no need to redeploy or newly deploy the application, thus achieving a technical effect of zero deployment. Moreover, from a program perspective, the embodiments of the present invention improve scalability.

[0075] Figure 7 FIG. 1 is a schematic diagram of the main flow of a method for processing a service request according to another reference embodiment of the present invention. As another embodiment of the present invention, Figure 7 As shown, the method for processing a service request may include:

[0076] Step 701: receiving a service request from a service system, and parsing the service request to obtain input service parameters.

[0077] The business system calls the dynamic computing service and passes in the business parameters. The dynamic computing service receives the business request passed in by the business system, parses the business request, and obtains the input business parameters. The input business parameters include the identifier of the computing script and the identifier of the business data. The input business parameters passed in when the business service calls the dynamic computing service are JSON objects, so the business system service can configure the data structure (i.e., input attributes) of the input business parameters according to different computing scripts.

[0078] Step 702 , determine whether the identifier of the calculation script is one of the identifiers of the configured calculation scripts; if so, execute step 703 ; if not, execute step 708 .

[0079] Step 703 , determine whether the input attribute corresponding to the identifier of the business data matches the identifier of the calculation script; if so, execute step 704 ; if not, execute step 708 .

[0080] Step 704: Acquire the business data from the database according to the identifier of the business data, and assemble the business data into a result object.

[0081] The input business parameters are only used to pass key identifiers. The actual data is still stored in relational or non-relational databases, such as (MySQL, MongoDB, HBASE, etc.); the corresponding detail row data is obtained from the database through the key identifier, and the data is assembled again and passed to the calculation script for calculation.

[0082] Step 705: calling the calculation script according to the identifier of the calculation script.

[0083] The calculation script is saved in the directory node of Zookeeper as the node value of the directory node; and the name of the target node is the identifier of the calculation script. Each calculation script is saved in the directory node of Zookeeper (based on the unique identifier of different calculation scripts as node, or based on other key values ​​as node). By inputting the identifier of the calculation script in the business parameter, the directory node -node in Zookeeper is matched, and the corresponding node value -value is obtained, thereby achieving the purpose of dynamically calling the calculation script.

[0084] Step 706: pass the calculation script and the result object to a rendering engine, and run the rendering engine to obtain output business parameters.

[0085] When the script calculation is completed, the returned output business parameters are JSON objects. The data structure of the output business parameters (i.e., the returned attributes) can also be configured according to different calculation scripts, thereby achieving the purpose of dynamically configuring the output business parameters.

[0086] Optionally, the rendering engine is Rhino, and the calculation script is a JavaScript calculation script. In the embodiment of the present invention, the input business parameters and the called calculation script are transmitted to the Rhino JavaScript rendering engine, and the engine outputs the result JSON object after running, which is then returned to the business system.

[0087] When the calculation script is adjusted according to business needs, the data structure of the input and output business parameters is modified, and the node value in Zookeeper (calculation script logic) is also modified. The business system can obtain the corresponding calculation results by calling the dynamic calculation service again, thus achieving the technical effect of zero deployment.

[0088] Step 707: Return the output service parameters to the service system.

[0089] Step 708: Return an error code and an error message to the business system.

[0090] In addition, the specific implementation content of the method for processing a service request in a reference embodiment of the present invention has been described in detail in the method for processing a service request described above, so the repeated content will not be described here.

[0092] Optionally, the assembling module 802 is further used for:

[0093] Determine whether the identifier of the calculation script is one of the identifiers of the configured calculation scripts; if so, continue to determine whether the input attributes corresponding to the identifier of the business data match the identifier of the calculation script; if not, return an error code and an error message to the business system; if the input attributes corresponding to the identifier of the business data match the identifier of the calculation script, obtain the business data from the database according to the identifier of the business data; if the input attributes corresponding to the identifier of the business data do not match the identifier of the calculation script, return an error code and an error message to the business system.

[0094] Optionally, the identification of the business data includes an item ID and a basic attribute ID of the item;

[0096] At least one piece of detail line data is obtained from the database according to the identifier of the business data, and the at least one piece of detail line data is assembled into a result object.

[0097] Optionally, the calculation script is saved in a directory node of Zookeeper as a node value of the directory node; and the name of the target node is an identifier of the calculation script.
