Unless otherwise defined, terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. Further, it will be understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and will not be interpreted in an idealized or overly formal sense.

FIG. 1 is a flow chart of a method 100 for generating a non-tax electronic ticket according to an embodiment of the invention. As shown in fig. 1, the method for generating non-tax electronic bills according to the embodiment of the present invention can quickly and accurately produce electronic bills in batches according to received JSON information, and can generate PDF-based electronic bills in batches, thereby realizing paperless invoicing; electronic signature information is added to a PDF file, and a built-in interface is called to verify the electronic signature on the bill, so that whether the source of the electronic bill is credible or not and whether the file is tampered or not are identified in real time; different system interfaces are called to realize the required operation process, the electronic bill requirements of different users can be met, and the use experience of the users is improved. The non-tax electronic bill generation method 100 provided by the embodiment of the invention starts from step 101, and obtains invoice data to be issued in step 101, and converts the obtained invoice data into a data object of a preset type.

Preferably, the preset type data object is a bean data object.

In the invention, after receiving the data information of the invoice to be issued in the JSON format, the corresponding entity class is selected according to the parameters in the data information, and the entity class is converted into the BEAN data object.

In step 102, the data object with the preset format is analyzed to obtain the bill parameter type and the parameter value corresponding to each bill parameter, and the bill layout file is determined according to the bill parameter information.

Preferably, before parsing the data object in the preset format, the method further includes:

and determining key fields in the data object with the preset format, and checking the length and the type of the determined key fields.

In the invention, after type conversion, the data object with the preset format is analyzed to obtain the bill parameter type and the parameter value corresponding to each bill parameter. And then, checking the dimensions such as length, type and the like of the key fields in the related entity classes, and selecting corresponding bill layout files and a generating method according to specific parameters after the checking is passed.

In step 103, filling the parameter value corresponding to each bill parameter into the bill layout file to obtain a first electronic invoice file in a preset format.

Preferably, the filling the parameter value corresponding to each bill parameter into the bill layout file to obtain a first electronic invoice file in a preset format includes:

for any bill parameter, determining the format of the parameter value corresponding to the any bill parameter according to the parameter type of the any bill parameter, and setting the format of the parameter value of the any bill parameter according to the format of the parameter value corresponding to the any bill parameter;

and filling the parameter value of each bill parameter with the set format to a corresponding position according to the preset coordinate set information so as to obtain a first electronic invoice file with the preset format.

Preferably, the preset format is a PDF format.

In step 104, the first electronic invoice file is signed to obtain a second electronic invoice file with a preset format.

Preferably, the signing the first electronic invoice file to obtain a second electronic invoice file in a preset format includes:

verifying the integrity of the first electronic invoice file, calling a signature and a preset signature position after the first invoice file passes the integrity verification, and signing the first electronic invoice file according to the preset signature position to obtain a second electronic invoice file in a preset format.

In the invention, after the bill format file is determined, the text formats such as fonts, word sizes and the like are set for the parameter values of the parameters according to the parameter types, and then the text contents (parameter values) are filled to corresponding positions according to the preset coordinate set information, so that the initial bill file in the PDF format, namely the first electronic invoice file, is generated. Subsequently, a signature operation is performed on the face of the first electronic invoice file.

After the text information filling operation is completed, only unit badges are signed and received (if the user needs to define the signature position by self, coordinate set information needs to be filled according to the requirement of the user).

The caller signs the incoming pdf file byte stream in the form of parameter, and usually the receipt corresponding to the pdf byte stream is covered with the electronic seal of the receipt unit. After the system completes the integrity check of the PDF stream, the system signs a signature (the system determines a template corresponding to the PDF stream according to a parameter (template identifier) specified by a user so as to achieve the purpose of signing a signature at a preset position of the template, or the user can self-define the signature position).

The corresponding relation between the interface and the application scene of the method of the invention is as follows:

the interface generates PDF and signs unit seal and stamp for generating a scene that a bill PDF covers two seals continuously, such as Taizhou non-tax receipt seal.

And the interface II generates PDF and signs unit seal for the department of health and accountability to generate PDF bill file and signs unit seal. Such as Wenzhou Wei Jie, Huzhou Wei Jie, etc.

The interface III reads in the bill byte stream information and signs the supervision seal for the financial department to add the supervision seal on the incoming pdf stream, and the incoming bill pdf byte stream is covered with the unit seal of receipt, so that whether the pdf stream is tampered or not needs to be checked at first, namely the integrity of the document is checked.

As shown in fig. 2, the process of generating a PDF file according to input information and signing unit badges and monitoring badges includes: converting the Json character string into a bean object; checking a key field; loading a preset invoice template according to the corresponding adoption number; setting a text format; filling the text content at the corresponding position according to the preset coordinate information; and adding a receipt unit and a supervision unit chapter at the corresponding position of the PDF file according to the preset coordinate or the appointed coordinate.

As shown in fig. 3, the flow of signing only unit badges after generating a PDF file from input information is similar to that of fig. 2, except that there is no need to monitor unit badges.

As shown in fig. 4, the process of signing and monitoring the stamp on the ticket surface after reading the byte stream information of the invoice data is as follows: loading a byte stream file according to the specified path, checking the PDF file, and adding a supervision unit chapter at the corresponding position of the PDF file according to the preset coordinate or the specified coordinate.

The method stores a plurality of templates in a PDF template library in advance to meet the requirements of different scenes; acquiring JSON data and converting the JSON data into a Bean object; acquiring a needed PDF plate type file template from the template library according to corresponding parameters; generating a PDF file according to the analyzed Bean object information and by combining a corresponding method; and adding electronic signature information to the PDF stream file. And analyzing and processing the received JSON information to generate a PDF file, and signing a unit seal and a supervision seal on the bill. And after reading the byte stream information of the specific bill, signing a supervision seal on the bill. The invention can realize the fast and accurate batch production of the electronic bills according to the received JSON information.

Fig. 5 is a schematic structural diagram of a non-tax electronic ticket generating system 500 according to an embodiment of the present invention.
