Description

Technical Field

[0001] This application relates to the field of data processing technology, and in particular to a method, apparatus, computer equipment, and storage medium for visualizing digital invoices. Background Technology

[0002] Fully digitized electronic invoices (referred to as digital invoices) do not require application but have the same legal effect as paper invoices, effectively preventing invoice fraud while greatly increasing the convenience of issuing invoices.

[0003] The VAT invoice integrated service platform provided by the tax authorities offers downloads of various formats of electronic invoices, including PDF (Powder Diffraction File), OFD (Open Fixed-layout Document), and XML (Extensible Markup Language). PDF format electronic invoices are primarily used as paper printouts for reimbursement and accounting purposes, and do not support verification of the validity of the invoice seal and electronic signature. OFD format electronic invoices are electronic vouchers for reimbursement and accounting archiving; their format is identical to PDF, but the validity of the invoice seal and electronic signature on OFD format invoices requires verification using a dedicated VAT electronic invoice reader, a complex process. XML format electronic invoices contain structured invoice data, including digital signatures, and their signature validity can be verified without specialized software; therefore, XML format electronic invoices are used for reimbursement and accounting archiving.

[0004] However, existing digital invoices are delivered as XML files, but the invoice content cannot be viewed directly in the XML file. Users need to go to the tax bureau's website to view the visualized invoice content, which is complicated and time-consuming, affecting the user experience. Summary of the Invention

[0005] The purpose of this application is to provide a method, apparatus, computer device, and storage medium for visualizing digital invoices, so as to solve the problem that structured digital invoice data cannot be visualized in the prior art.

[0017] Obtain the display row height, column width, character space width, and font size information of the purchase and sales details;

[0018] Determine which purchase and sales details can be displayed on a new line in the purchase and sales details. Based on the display row height and column width, determine whether each purchase and sales detail that can be displayed on a new line needs to be displayed on a new line. If it needs to be displayed on a new line, then display it on a new line to obtain the final display height and the first display range.

[0019] Based on the character space width and font size information, the character space width and font size of the non-wrapable purchase and sales details are adjusted to obtain the second display area;

[0020] The display range of the purchase and sales details on the visualization page is determined based on the first display range and the second display range.

[0021] Furthermore, the step of obtaining the associated information of the digital invoice and generating a QR code based on the target node information and the associated information includes:

[0022] Extract the taxpayer's coding information from the displayable node information, dynamically obtain the tax bureau's seal based on the coding information, obtain the association information of the digital invoice, and generate a QR code based on the target node information and the tax bureau's seal.

[0023] Furthermore, after generating the visualization page for the digital invoice, the method further includes:

[0024] Save the address of the visualization page that displays the QR code, or generate and save an access QR code based on the address of the visualization page that displays the QR code, so that target users can view the visualization page through the address or the access QR code.

[0044] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application, are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0045] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0046] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0047] like Figure 1 As shown, system architecture 100 may include terminal devices 101, 102, and 103, a network 104, and a server 105. Network 104 serves as the medium for providing communication links between terminal devices 101, 102, and 103 and server 105. Network 104 may include various connection types, such as wired or wireless communication links, or fiber optic cables, etc.

[0048] Users can use terminal devices 101, 102, and 103 to interact with server 105 via network 104 to receive or send messages, etc. Various communication client applications can be installed on terminal devices 101, 102, and 103, such as web browser applications, shopping applications, search applications, instant messaging tools, email clients, social media platform software, etc.

[0049] Terminal devices 101, 102, and 103 can be various electronic devices with displays and web browsing capabilities, including but not limited to smartphones, tablets, laptops, and desktop computers.

[0050] Server 105 can be a server that provides various services, such as a backend server that supports the pages displayed on terminal devices 101, 102, and 103.

[0051] It should be noted that the digital invoice visualization method provided in this application embodiment is generally executed by a server, and correspondingly, the digital invoice visualization device is generally set in the server.

[0052] It should be understood that Figure 1 The number of terminal devices, networks, and servers shown is merely illustrative. Depending on implementation needs, any number of terminal devices, networks, and servers can be included.

[0053] Continue to refer to Figure 2 A flowchart illustrating an embodiment of a method for visualizing digital invoices according to this application is shown. The method for visualizing digital invoices includes the following steps S21 to S24:

[0054] Step S21: Receive the visualization instruction of the digital invoice, obtain the structured digital invoice data according to the visualization instruction, parse the nodes of the structured digital invoice data, and obtain several displayable node information.

[0055] In this step, the visualization command for the digital invoice can be initiated by the user or automatically triggered by the server providing the digital invoice visualization service. The structured digital invoice data is digital invoice data in XML format. By parsing the data nodes in the XML file, several node information that can be used for visualization can be obtained. This node information includes various information on the invoice, such as the invoice name, invoice code and number, number of copies and purpose (purchase and sales details), invoice date, stamp, etc.

[0056] Step S22: Determine the visualization page format according to the visualization instructions, and generate corresponding page configuration information according to the visualization page format;

[0057] In this step, the visualization page formats include PDF and OFD. For different formats, the corresponding page building plugin can be used to generate page configuration information.

[0058] For OFD format, different elements of images and text have corresponding display tags, such as MediaFile for images and TextCode for text. When generating page configuration information, the page building plugin Freemark can be used to define variable names. The variable names are placed in the tags to form a configuration file, and various digital content objects such as text and images are fixed in the layout according to certain rules. In subsequent step S24, Freemark can be used to uniformly replace the tags in the configuration file to generate a visual page.

[0059] For PDF format, an HTML page can be generated first. Specifically, the HTML page provides different display elements such as text and tables. Combined with CSS styles, the information on the electronic invoice is drawn into a page that meets the layout requirements. Then, the ITextRenderer provided by the page building plugin IText is used to convert the HTML page into a PDF file.

[0060] Step S23: Obtain target node information from the displayable node information and obtain the associated information of the digital invoice, and generate a QR code based on the target node information and the associated information.

[0061] In this embodiment, the QR code mainly includes key invoice information, which is dynamically generated based on the current digital invoice. The target node information is the key invoice information in the displayable node information, while the associated information mainly refers to the tax bureau's seal.

[0062] Accordingly, in some embodiments, the step of obtaining the association information of the digital invoice and generating a QR code based on the target node information and the association information includes: extracting the taxpayer's coding information from the displayable node information; dynamically obtaining the tax bureau seal based on the coding information to obtain the association information of the digital invoice; and generating a QR code based on the target node information and the tax bureau seal. The generated QR code will contain a tax bureau icon in the middle to improve the identification of the invoice's source. For different types of digital invoices, the tax bureau seal will be dynamically switched according to the tax bureau code. Each taxpayer has a corresponding tax bureau code, and the second to fifth digits of the tax bureau code are the regional code. By pre-obtaining tax bureau seals from different regions and naming the seals according to the regional codes, when generating the QR code, the taxpayer is obtained based on the parsed node information, and the corresponding tax bureau code is searched to obtain the specified tax bureau seal.

[0063] Step S24: Generate a digital invoice visualization page using the displayable node information and the page configuration information, and merge and display the QR code at the target position on the visualization page.

[0064] In this step, the visual page and QR code can be overlaid using the Java built-in object Graphics2D to generate the final display page.

[0065] In some embodiments, such as Figure 3 As shown, the step of generating a digital invoice visualization page using the displayable node information and the page configuration information includes:

[0066] Step S31: Obtain the page display element tags in the page configuration information, and determine the final displayed node information from the displayable node information through the page display element tags; in this step, specifically, the name matching the page display element tags is searched from the node information through the page display element tags to determine the final displayed node information.

[0067] Step S32: Determine whether to adjust the page configuration information based on the final displayed node information. If yes, proceed to step S33; otherwise, proceed to step S34.

[0068] Step S33: Adjust the page configuration information and generate a visual page for the digital invoice based on the final displayed node information and the adjusted page configuration information.

[0069] Step S34: Generate a visualization page for the digital invoice based on the final displayed node information and the page configuration information.

[0070] For step S32, as Figure 4 As shown, the step of determining whether to adjust the page configuration information based on the finally displayed node information includes:

[0071] Step S41: Obtain the purchase and sales details in the final displayed node information, and determine its display range on the visualization page based on the purchase and sales details;

[0072] Step S42: Determine whether the display range exceeds the pre-configured display range in the page configuration information. If yes, proceed to step S43; otherwise, proceed to step S44.

[0073] Step S43 adjusts the page configuration information;

[0074] Step S44: Do not adjust the page configuration information. Different digital invoices have different purchase and sales details, so their display range will vary. Therefore, to ensure complete visualization, the configuration file can be adjusted according to the actual display range to improve the visualization effect.

[0075] In some embodiments, for step S41, such as Figure 5 As shown, the step of determining the display scope of the purchase and sales details on the visualization page includes:

[0076] Step S51: Obtain the display row height, column width, character space width, and font size information of the purchase and sales details;

[0077] Step S52: Determine which purchase and sales details can be displayed on a new line in the purchase and sales details. Based on the display row height and column width, determine whether each purchase and sales detail that can be displayed on a new line needs to be displayed on a new line. If so, display it on a new line to obtain the final display height and the first display range.

[0078] Step S53: Adjust the character space and font size of the non-wrapable purchase and sales details according to the character space width and font size information to obtain the second display area;

[0079] Step S54: Determine the display range of the purchase and sales details on the visualization page based on the first display range and the second display range.

[0080] In this embodiment, for steps S51 and S52, regarding the display row height, for standard layout documents, the height of each row of invoice purchase and sales details is fixed at 4.5 units. Some column widths are also fixed units; for example, the item name length is fixed at 37 units, with Chinese characters occupying 3.175 units and non-Chinese characters occupying 1.5875 units each. The final number of rows to be displayed for the purchase and sales name is determined through calculation. For the display column width, each column width is also fixed; for example, the item name length is fixed at 37 units, and the specification / model length is 24 units, with Chinese characters occupying 3.175 units and non-Chinese characters occupying 1.5875 units each. The total length occupied by the current content can be obtained, thus dividing and displaying it on separate lines. Combined with the total number of purchase and sales details, the total number of rows in the current invoice is determined to obtain the height of the purchase and sales details area, thus obtaining the first display range. This first display range determines the total height of the visualized electronic invoice.

[0081] Regarding the character placement width, setting an unreasonable character width can lead to excessive character spacing or character overlap. The system identifies whether a character is Chinese or not based on its Unicode encoding, setting the width to 3.175 units for Chinese characters and 1.5875 units for each non-Chinese character. For the font size, since the total number of digits for unit price and quantity is limited to a maximum of 17, including the decimal point (maximum length 18), and each column width is 25 units, with numbers occupying 1.5875 units, the maximum display size is 15 digits. Exceeding 15 digits will result in incomplete display and character overlap. If the total content length is less than or equal to 15 digits, the font size is 3.175; if it exceeds 15 digits, the font size is set to 2.8222. By combining adjustments to the character placement width and font size, a second display area can be achieved.

[0082] The above steps enable automatic line breaks and downward expansion of the height of multiple purchase and sales details on digital invoices, as well as dynamic adaptation of the width of Chinese characters, letters, numbers, and other content in the digital invoice information and dynamic automatic adjustment of font size.

[0083] In some embodiments, after generating the visualization page for digital invoices, the method further includes: saving the address of the visualization page that integrates the QR code or generating and saving an access QR code based on the address of the visualization page that integrates the QR code, so that target users can view the visualization page through the address or the access QR code. This step enables rapid distribution of the visualization page and access from multiple clients, improving user viewing efficiency.

[0084] Compared with the prior art, the embodiments of this application have the following main advantages:

[0085] This application embodiment obtains node information of structured digital invoice data, generates page configuration information according to the required visualization page format, generates a QR code based on the target node information and the associated information, and generates a visualization page based on the node information, page configuration information and QR code, thereby enabling users to quickly view invoice information of digital invoices presented in structured data, improving convenience and saving time.
