Description

Background Art

[0002] In the prior art, for the backend system that the application client relies on, due to the continuous upgrade of the application version, the content of the source data corresponding to the same function in the client remains unchanged, but the output source data is required to have a different data format from the previous version.

[0003] In order to solve the above problems, in the prior art, a new HTTP (Hyper Text Transfer Protocol) interface may be added, or data conversion logic may be designed for compatibility processing.

[0004] However, if it is impossible to require users to upgrade the application client forcibly, the back-end system must maintain the back-end output data format and related conversion method codes for multiple APP versions for a long time, which increases the system burden.

[0005] Therefore, a new data conversion method needs to be provided.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present invention, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0060] Example embodiments will now be described more fully with reference to the accompanying drawings. However, example embodiments can be implemented in a variety of forms and should not be construed as being limited to the examples set forth herein; on the contrary, these embodiments are provided so that the present invention will be more comprehensive and complete, and the concept of the example embodiments will be fully conveyed to those skilled in the art. The described features, structures, or characteristics may be combined in one or more embodiments in any suitable manner. In the following description, many specific details are provided to provide a full understanding of the embodiments of the present invention. However, those skilled in the art will appreciate that the technical solutions of the present invention may be practiced while omitting one or more of the specific details, or other methods, components, devices, steps, etc. may be adopted. In other cases, known technical solutions are not shown or described in detail to avoid obscuring various aspects of the present invention.

[0061] In addition, the accompanying drawings are only schematic illustrations of the present invention and are not necessarily drawn to scale. The same reference numerals in the figures represent the same or similar parts, and their repeated description will be omitted. Some of the block diagrams shown in the accompanying drawings are functional entities and do not necessarily correspond to physically or logically independent entities. These functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0062] Existing business websites usually adopt a front-end and back-end separation architecture. The front-end system provides page rendering functions, and the back-end service provides output data through the HTTP protocol. The output data is usually in JSON (JavaScript Object Notation) format. The source data provided by the back-end service contains the same information as the data that the front-end system needs to display, but has different data structures. Usually, when the back-end service needs to output different output data, different HTTP interfaces must be provided for different output data. The data in the interface is usually obtained from a database or RPC (Remote Procedure Call), and the conversion logic of converting the source data into the data structure required by the front-end system is fixed in the code. When the source data structure or the data structure required by the front-end system changes, the code corresponding to the conversion logic must be modified and re-applied for online, forming a maintenance cost for the back-end service.

[0063] In addition, in the backend services that the application software client (Android and IOS) relies on, since the source data corresponding to the same function of the new version of the application software client is the same as that of the old version of the client, the data output by the backend service may require different data structures or contents. In the prior art, the compatibility of the new and old versions is processed by adding HTTP interfaces or data conversion logic. When it is impossible to force users to upgrade the client version, the backend service must maintain the backend service output data format and related conversion logic code for multiple client versions for a long time, resulting in a heavy burden on the system and increased maintenance costs.

[0064] Based on one or more of the above problems, this exemplary embodiment first provides a data conversion method, which can be run on a server. Of course, those skilled in the art can also run the method of the present invention on other platforms as required, and this exemplary embodiment does not specifically limit this. Figure 1 As shown, the data conversion method may include the following steps:

[0065] Step S110. Respond to the data display request of the client, obtain a data conversion template and source data corresponding to the data display request, and parse the data conversion template to obtain one or more first sub-nodes included in the data conversion template;

[0066] Step S120. When it is determined that any of the first child nodes is a leaf node, a second child node corresponding to the first child node is determined in the source data according to the mapping relationship included in the first child node;

[0067] Step S130. According to the data type required by the first child node, the data format of the node data included in the second child node is converted, and target output data is generated according to the node data after the format conversion;

[0068] Step S140: Send the target output data to the client, so that the client displays the target output data.

[0069] The above-mentioned data conversion method responds to the data display request of the client, obtains the data conversion template and source data corresponding to the data display request; parses the data conversion template to obtain the first child node included in the data conversion template; when determining that the first child node is a leaf node, determines the second child node corresponding to the first child node according to the mapping relationship between the second child node in the source data included in the first child node and the first child node; according to the data type of the first child node included in the data conversion template, converts the output data corresponding to the second child node into the data type of the first child node, and displays it in the client. Since the data conversion template corresponding to the request can be determined according to the data display request of the client, and the format of the source data corresponding to the client display data is converted according to the data conversion template, the business logic changes generated when the output data of the client changes are reduced, the system burden is reduced and the maintenance cost is reduced; at the same time, since the source data corresponding to the client data display request can be determined according to the mapping relationship included in the leaf node, the efficiency of data conversion is improved, and the data format of the source data is converted based on the data type required by the first child node, the efficiency of data conversion is improved.

[0070] Hereinafter, each step involved in the data conversion method according to the exemplary embodiment of the present disclosure is explained and illustrated in detail.

[0071] First, the application scenarios and invention objectives of the exemplary embodiments of the present disclosure are explained and illustrated.

[0072] Specifically, the example embodiments of the present disclosure can be used in device terminals with separated front-end and back-end, mainly through customizing data conversion templates. When the structure of the data that the front-end system needs to display is different from the data structure of the source data, or when the structure of the source data provided by the back-end service changes, it can reduce business logic changes and reduce the maintenance cost of the back-end service.

[0073] The example embodiment of the present disclosure is based on a customized data conversion template. After obtaining the source data corresponding to the data to be displayed on the front end, a mapping relationship between the source data and the output data is established through the customized data conversion template. Through the mapping relationship and the data format of the data to be displayed in the data conversion template, the source data is converted into the corresponding target output data and displayed on the client. The source data can be configured with multiple data conversion templates, and each data conversion template has corresponding target output data. When the format of the data to be displayed on the front end changes or the data format of the source data changes, by calling different data conversion templates, the business logic changes when the changes occur are reduced, and the maintenance cost is reduced.

[0074] Next, the data conversion system involved in the exemplary embodiment of the present disclosure is explained and illustrated. Figure 2 As shown, the data conversion system may include a source data processor 210, a conversion template processor 220, a data converter 230, and a data output processor 240. The source data processor 210 is used to read and parse the source data, obtain the source data memory object, and store the source data memory object in the system memory; the conversion template processor 220 is connected to the source data processor 210 through a network, and is used to read and parse the data conversion template, generate a data conversion template memory object including the structure of the target output data and the mapping relationship with the source data, and store the data conversion template memory object in the system memory; the data converter 230 is connected to the source data processor 210 and the conversion template processor 220 through a network, and is used to read the source data memory object and the data conversion template memory object, convert the source data into the target output data memory object according to the data conversion method defined by the data converter, and store the target output data memory object in the system memory; the data output processor 240 is connected to the data converter 230 through a network, and is used to read the target output data memory object, and output the target output data included in the target output memory object.

[0075] The following will be combined Figure 2 Steps S110 to S130 are explained and described.

[0076] In step S110, in response to the data display request of the client, a data conversion template and source data corresponding to the data display request are obtained, and the data conversion template is parsed to obtain one or more first sub-nodes included in the data conversion template.

[0077] The data display request is initiated by the client, and the data display request includes the target output data to be displayed, the data type of the target output data, and the name of the data conversion template corresponding to the data type of the target output data. When the server responds to the client's data display request, it needs to determine the data conversion template corresponding to the data display request according to the name of the data conversion template included in the data display request.

[0078] Before obtaining the data conversion template, the server needs to generate a data conversion template based on the content of the target output data that the client needs to display and the data structure of the target output data. For details, refer to Figure 3 As shown, obtaining a data conversion template corresponding to the data display request may include:

[0079] Step S310. Generate the data conversion template according to the data type of the target output data displayed by the client and the mapping relationship between the target output data and the source data;

[0080] Step S320: Determine a data conversion template corresponding to the data display request according to the name of the data conversion template included in the data display request.

[0081] Step S310 and step S320 are explained and illustrated below. Specifically, the data conversion template is a tree structure, which is used to describe the structure of the target output data. Each child node in the tree structure at least includes a node name (name) and a data type (type). When the child node in the tree structure is a leaf node, that is, the child node does not have a next-level child node, and the leaf node includes a node name, a node type, and a mapping relationship (value) between the target output data and the source data, wherein the node name can be a child node name or a field name of the target output data, the node type is the data type of the target output data, and the mapping relationship is a mapping relationship between the first child node in the data conversion template and the second child node included in the source data, and the second child node of the source data included in the mapping relationship is the child node corresponding to the target output data. Since the path from the root node of the source data to a certain leaf node is unique, the mapping relationship can be represented in the form of a path.

[0082] For example, the root node of the source data may include three child nodes: source_1, source_2, and source_3; for the child node source_1, the data type is a collection type, which may include: source_1_1, the data type is a collection type, which may include the child node source_1_1_1, the data type is an array type, and the node data includes "aaa", "bbb", and "ccc"; source_1_2, the data type is a basic type, and the node data is 123; for the child node source_2, it may include the child node source_2_1, the data type is a collection type, and the node data includes: "skuId": 8934378, "venderId": 1; for the child node source_3, the data type is an array type, which may include the child node Point source_3_1, the data type is a collection type, and the data nodes include "promotionId": "aaa", "promotionType": 6 and "promotionId": "bbb", "promotionType": 10; the child node source_3_2, the data type is an array type, and may include the child node source_3_2_1, the data type is a collection type, and the node data may include: "shopId": 111, "shopName": "JD1", "shopId": 112, "shopName": "JD2", "shopId": 2221, "shopName": "JX1" and "shopId": 112, "shopName": "JX2".

[0083] When it is necessary to identify the source_2_2 child node, "." can be used as the path separator from the root node to the node, that is, source_2.source_2_2 can be used to identify the source_2_2 child node, where other symbols can also be used as path separators, which are not specifically limited in this example embodiment. In addition, when the path from the leaf node to the root node contains child nodes whose node type is an array type, other special identifiers need to be added. For example, "#." can be added after the child node whose node type is an array type as an identifier. For example, source_3_2_1 can be identified by source_3.source_3_2.#.source_3_2_1, where other special characters can also be used to identify child nodes whose node type is an array type, which are not specifically limited in this example embodiment.

[0084] The name (name) of the subnode included in the data conversion template is the field name of the target output data, the type (type) is the data type of the data node included in the second subnode included in the data conversion template, and the value value is the mapping relationship between the source data and the target display data, and the specific form is the path of the source data subnode.

[0085] After the data conversion template is generated, the server determines the data conversion template corresponding to the data display request according to the name of the data conversion template included in the data display request.

[0086] In this example embodiment, reference Figure 4 As shown, parsing the data conversion template to obtain one or more first sub-nodes included in the data conversion template may include steps S410 to S430:

[0087] Step S410: Parse the data conversion template to obtain a data conversion template memory object; wherein the data conversion template memory object is a tree structure;

[0088] Step S420: Parse the data conversion template memory object to obtain the root node included in the data conversion template memory object;

[0089] Step S430: According to the root node, obtain one or more first child nodes included in the data conversion template memory object.

[0090] The following explains and illustrates steps S410 to S430. Specifically, first, the conversion template processor 220 reads the data conversion template and parses the data conversion template to obtain a data conversion template memory object including the data type of the target output data and the mapping relationship with the source data, wherein the data conversion template memory object is a tree structure; then, the conversion template processor 220 parses the data conversion template memory object to obtain the root node included in the memory object; finally, traverse the root node to obtain one or more first child nodes included in the data conversion template memory object.

[0091] For example, when the client needs to display the target output data, that is, the node names of the data conversion template are: target_1, target_2 and target_3, among which, the child node included in target_1 can be: target_1_1, the data type to be displayed is an array type, and the corresponding source data node is source_1.source_1_1.source_1_1_1; the data type to be displayed by target_2 is a collection type, and the corresponding source data nodes are: source_2.source_2_1.skuId; the child nodes included in target_3 can be: the collection target_3_1, target_3_2, and the collection target_3_1, target_3_2; the data type to be displayed by target_3_1 is a collection type, and the corresponding source data node is source_3.#.source_3_1.promotionId; the data type to be displayed by target_3_2 is an array type, and the corresponding source data node is source_3.#.source_3_2.#.source_3_2_1.shopId. Parsing the data conversion template can obtain Figure 5 The data transformation template memory object shown.

[0092] In step S120, when it is determined that any of the first sub-nodes is a leaf node, a second sub-node corresponding to the first sub-node is determined in the source data according to a mapping relationship included in the first sub-node.

[0093] Among them, a leaf node is a child node that does not have a next-level child node. Specifically, the data converter 230 reads the data conversion template memory object. When the child node included in the data conversion template memory object is a leaf node, the second child node included in the source data corresponding to the leaf node is determined based on the mapping relationship between the target output data included in the leaf node and the source data.

[0094] In this example embodiment, reference Figure 6 As shown, before determining the second sub-node corresponding to the first sub-node in the source data, the data conversion method further includes steps S610 to S630:

[0095] Step S610: Read the source data and parse the source data into a source data memory object; wherein the source data memory object is a tree structure;

[0096] Step S620. Identify the data type of the node data included in one or more second child nodes included in the source data memory object; wherein the data type of the node data included in the second child node is one of a set type, an array type and a basic type;

[0097] Step S630: Determine whether the data type required by the first child node and the data type of the data node included in the second child node meet the conversion conditions.

[0098] The following will explain and illustrate steps S610 to S630. Specifically, first, the data converter 230 reads and parses the source data corresponding to the target output data, and parses it into a source data memory object, wherein the source data processor 220 supports reading source data in JSON or YAML (YAML Ain't a Markup Language, YAML is not a markup language) format, and the source data memory object is a tree structure. The source data memory object obtained by the data converter after parsing the source data recorded in steps S310 and S320 can be referred to. Figure 7 As shown; Then, when the source data is parsed into a tree structure, since JSON or YAML contains three types of data structures, namely, key-value mapping type (map type, collection type), array type (array type) and base type (base type, a general term for string and numeric types), it is necessary to identify the data type of the node data included in one or more second child nodes included in the source data, and the identification may include identifying the node name of the second child node and the data type of the second node. In addition, since the array type data contains multiple output data, when parsed into a tree structure, the output data in the array can be merged into a data child node, and the root node may not contain any specific data, but only serve as a connection point for each data node; Finally, after identifying the data type of the node data included in the child node of the source data, it is also necessary to determine whether the data type of the node data included in the second child node of the source data and the node type required by the first child node included in the data conversion template can be converted to each other.

[0099] By identifying the data type of the node data included in the second child node of the source data, and judging whether the data type of the node data included in the second child node and the data type required by the first child node can be converted to each other before data conversion, the error rate of data conversion is reduced and the efficiency of data conversion is improved.

[0100] For further reference, Figure 8As shown, judging whether the data type required by the first sub-node and the data type of the data node included in the second sub-node meet the conversion condition may include steps S810 to S830:

[0101] Step S810. Record the data type required by one or more first child nodes included in the data conversion template memory object;

[0102] Step S820: Determine whether the data type required by the first child node and the data type of the node data included in the second child node can be converted to each other;

[0103] Step S830: When the data type required by the first sub-node and the data type of the node data included in the second sub-node can be converted to each other, the second sub-node is determined as the sub-node corresponding to the first sub-node.

[0104] Steps S810 to S830 are explained and illustrated below. The data type required by the first child node may also be any one of a map type, an array type, and a base type. The data type required by the first child node included in the data conversion template memory object is recorded, and it is determined whether the data type required by the first child node and the data type of the node data included in the second child node can be converted to each other. For example, when the data type required by the first child node is a map type and the data type of the node data included in the second child node is an array type, since the map type data cannot be converted into array type data, the first child node and the second child node cannot be converted to each other. When the data type required by the first child node and the data type of the node data included in the second child node can be converted to each other, the second child node of the source data is determined as the child node corresponding to the first child node included in the data conversion template.

[0105] Furthermore, determining whether the data type required by the first child node and the data type of the data node included in the second child node meet the conversion condition further includes:

[0106] Determine a first number of array-type child nodes included in a path from the first child node to the root node of the data conversion template memory object;

[0107] Determine a second number of array type nodes included in a path from a second child node corresponding to the first child node to a root node of the source data memory object;

[0108] It is determined whether the first number is the same as the second number, and when it is determined that the first number is the same as the second number, the second sub-node is determined as a sub-node corresponding to the first sub-node.

[0109] Specifically, since the path from the child node to the root node is unique, it is possible to determine whether a conversion can occur between the two parties by determining whether the number of array-type child nodes included in the path from the leaf node to the root node in the data conversion template memory object is the same as the number of array-type child nodes included in the path from the leaf node to the root node in the source data memory object. When the first number of array-type child nodes included in the path from the first child node to the root node in the data conversion template memory object is the same as the second number of array-type child nodes included in the path from the second child node to the root node in the source data memory template, the second child node can be determined as the child node corresponding to the first child node.

[0110] When it is determined that the first sub-node and the second sub-node meet the conditions for mutual conversion, the sub-node of the data conversion template memory object can be replaced with the sub-node of the source data memory object through the data converter 230.

[0111] In step S130, the data format of the node data included in the second sub-node is converted according to the data type required by the first sub-node, and target output data is generated according to the node data after the format conversion.

[0112] In this exemplary embodiment, converting the data format of the node data included in the second sub-node according to the data type required by the first sub-node includes:

[0113] Determine whether the data type required by the first child node is the same as the data type of the node data included in the second child node;

[0114] When the data type required by the first subnode is the same as the data type of the node data included in the second subnode, taking the node data included in the second subnode as the target output data;

[0115] When the data type required by the first subnode is different from the data type of the node data included in the second subnode, the node data included in the second subnode is converted according to the data type required by the first subnode to obtain target output data.

[0116] Specifically, when the data converter 230 converts the data nodes in the data conversion template, it first determines whether the data type required by the first child node is the same as the data type of the node data included in the second child node. When the data type required by the first child node is the same as the data type of the node data included in the second child node, there is no need to convert the format of the source data. It is only necessary to output the target output data required to be displayed by the client through the data output processor 240 based on the mapping relationship between the target output data and the source data included in the data conversion template; when the data type required by the first child node is different from the data type of the node data included in the second child node, it is first necessary to convert the acquired source data into data consistent with the data type of the target output data required to be displayed by the client, and display the target output data on the client through the data output processor 240, wherein the format of the target output data output by the data output processor 240 can be JSON type or YAML type, which is not specially limited in this example embodiment. According to the source data recorded in steps S310 and S320 and the data conversion template recorded in steps S410-S430, the target output data can be obtained. For example, according to the mapping relationship included in the sub-node target_1_1 in the data conversion template, the target output data corresponding to the sub-node can be obtained as "aaa", "bbb", and "ccc"; the target output data corresponding to the sub-node target_2 is 8934378, and the target output data corresponding to the sub-node sets target_3_1 and target_3_2 included in the sub-node target_3 are: "aaaaaaaaaaaa" and 111, 112; the target output data corresponding to the other set target_3_1 and target_3_2 are: "bbbbbbbbbb" and 2221, 2222.

[0117] In step S140, the target output data is sent to the client, so that the client displays the target output data.

[0118] After obtaining the target output data through the data converter 230, the data converter saves the target output data in the system memory to obtain the target output data memory object. The data output processor 240 reads the target output data memory object saved in the system memory and outputs the target output data included in the target memory object to the client, so that the client displays the target data.

[0119] The data conversion method and data conversion system provided by the exemplary embodiments of the present disclosure have at least the following advantages: a data conversion template is generated according to the target output data that the client needs to display and the mapping relationship between the target output data and the source data, and the source data is replaced according to the data conversion template, thereby improving the front-end and back-end data conversion efficiency and reducing the system burden.

[0120] The following, combined Fig. 9 The data conversion method of the exemplary embodiment of the present disclosure is further explained and illustrated. The data conversion method may include the following steps:

[0124] Step S940. Record the node name and node type of the child node;

[0125] Step S950. Determine whether the child node is a leaf node;

[0126] Step S960. When the child node is a leaf node, determine the child node of the source data corresponding to the leaf node according to the mapping relationship between the leaf node and the source data; when the child node is not a leaf node, return to step S930;

[0127] Step S970: Parse the sub-nodes of the source data and replace the leaf nodes of the data conversion template with the sub-nodes of the source data;

[0128] Step S980. Convert all leaf nodes in the data conversion template into corresponding child nodes of the source data to obtain the target output data memory object;
