Electronic invoice generation method

Abstract

The invention discloses an electronic invoice generation method. The method comprises the steps of generating an electronic invoice layout file; creating a thread; analyzing the invoicing data; filling in part of signature structure information; serializing the OFD data model; calculating an OFD internal file abstract; serializing the memory model of the signature structure into a Sigatore.xml file, and calculating a Sigatore.xml abstract value; calling a signature service, and sending an abstract value to request signature data; and calling a cipher machine to calculate a signature value andpackaging the signature value into signature data to return to the format service. The invention discloses an electronic invoice generation method. A signature data structure is directly generated through a format service; the signature service does not need to analyze the OFD file again; the signature service only calculates the signature data, only the abstract value and the signature data are transmitted between the format service and the signature service, and the format service simplifies the dynamic calculation step by adopting a set table technology, so that the calculation amount of the format service and the signature service can be reduced at the same time, the network transmission overhead is reduced, the resource occupation is greatly reduced, and the processing efficiency is improved.

Description

technical field [0001] This application relates to the technical field of electronic invoices, in particular to a method for generating electronic invoices. Background technique [0002] The electronic invoice is obtained after adopting the OFD format file format and affixing an electronic signature. There are mainly two technical fields involved in the process of document generation, layout technology and security technology. The traditional method is to integrate the format generation service and signature service by the electronic invoice issuing system (see figure 1 ), call the layout service package to generate the coupon, and then call the signature service to stamp the supervision seal of the tax bureau. The detailed process is as follows: [0003] 1. The electronic invoice issuing system calls the layout generation service and sends the invoicing data; [0004] 2. The format generation service parses the billing data, selects the invoice template and parses and ge...

Problems solved by technology

[0015] The traditional electronic invoice issuing system simply integrates format service and signature service, which often faces the problem of service performance mismatch. For example, the format service can support 500TPS, while the signature service can only support 300TPS. For the synchronous invoicing system, according to Based on the wooden barrel principle, the overall billing performance can only reach 300TPS at most

On the one hand, this problem is caused by the fact that format and security are two completely different technical fields. In terms of deployment, two services are usually deployed separately. On the other hand, because the format is the carrier of electronic signatures, stamping electronic The process is bound to use format analysis technology to re-analyze and package the documents to be signed

In short, the technical fragmentation leads to a large number of repetitive calculations in the process of generating electronic invoices, which ultimately makes it difficult to achieve satisfactory performance.
