At present, in the financial field, both parties often need to sign a plurality of electronic contract books of different types on line, and different business products and different channels need to use respective contract templates, so that the types and styles of the contracts are various. And the client information, interest rate, contract clauses, repayment plan and the like in the text content of the online signed contract are dynamically changed. Besides simple text replacement, part of the contract content also relates to more complicated and diversified requirements, such as fonts, text colors, pictures, dynamic tables and the like, which also need to be dynamically changed according to actual conditions. Most of the existing electronic contract signing implementation methods are limited to simple text replacement and cannot meet the requirements of business development.
Based on this, the embodiments of the present specification provide an electronic contract generation signing method based on a parameter template, so as to use a word document as the template on the basis of ensuring the contract effectiveness, support dynamic modification of multi-style content, support direct editing of replacement document parameter content, and write in various content styles as required, and effectively ensure the document format of the contract, maximally ensure the rigor of the contract document, and meet the user requirements.
Fig. 1 is a schematic application scenario of an electronic contract generation and signing method based on a parameter template according to one or more embodiments of the present specification, which is illustrated by a requesting user, and as shown in fig. 1, the scenario includes: the system comprises a terminal device of a requester user, a service system database server, an FTP server message queue, an electronic contract generation and signing device based on a parameter template, a cache server, a signature system database server and an electronic signature service.
The terminal equipment can be a mobile phone, a tablet computer, a desktop computer, a portable notebook computer and the like; the cache server and the signature system database server store data, such as related data of electronic contracts.
Specifically, the terminal device of the requester user sends a contract signing request to the parameter template-based electronic contract generating and signing apparatus of the access service system according to the parameter information of the target electronic contract to be created in response to the contract creating operation of the contract signing requester user. The electronic contract generating and signing device calls a contract template corresponding to the contract signing request and identifies all preset parameters and positions of the preset parameters in the contract template; generating a rendering strategy corresponding to the preset parameters, converting the parameter information into rendering parameters according to the rendering strategy, and filling the rendering parameters into a contract template correspondingly; converting the WORD document filled with the rendering parameters into a PDF (Portable document Format) file; and calling the electronic signature service to execute electronic contract signing. And sends the signing result information to the corresponding terminal equipment of the requesting user.
Based on the application scenario architecture, one or more embodiments of the present specification provide an electronic contract generation and signing method based on a parameter template. Fig. 2 is a flowchart of a method for generating and signing an electronic contract based on a parameter template according to one or more embodiments of the present specification, where the method in fig. 2 can be performed by the electronic contract generating and signing apparatus based on a parameter template in fig. 2, as shown in fig. 2, and the method includes the following steps:
s100: acquiring a contract signing request sent by a contract signing requester; wherein the signing contract request includes parameter information of a target electronic contract to be created.
In one implementation, the requesting user operates his terminal device, selects target template information corresponding to a target electronic contract to be created among template information (such as template names) of a plurality of preset contract templates, and edits user identification information of each signing user of the target electronic contract to be created, replacement contents of the target electronic contract, and the like. The terminal equipment determines the template identification information of the contract template corresponding to the acquired target template information, the user identification information of each signing party user, the replacement content and the like as parameter information, and sends a signing contract request to the electronic contract generation signing device according to the parameter information.
Note that the present application does not limit the signing party, and may be an individual person or an enterprise or public institution.
S200: acquiring a contract template corresponding to the contract signing request; wherein the contract template is a WORD document.
The invention calls the corresponding contract template in the database based on the target template information in the contract signing request. It is emphasized that the contract template of the present invention is a WORD document, and specifically a DOC document in DOC format, as a template.
The applicant makes the following remarks on the definition:
the electronic contract and the paper contract are consistent in manufacturing process and all involve the steps of drafting, confirming, examining and approving, signing, sending and the like. The electronic contract making-up link involves the operation of performing customized filling on an electronic contract template by using client data. In the art, there are currently two main approaches:
(1) the first scheme is as follows: PDF, an international standard format in the field of printing, has become the format of choice for making electronic contracts because of its excellent performance in layout, rendering, cross-platform, public, interactive, and security. The universal practice in the industry is to add a form field on a PDF file with reserved blank filling data space, wherein the form field can record relevant attributes such as position, size, font, name and the like, then use the PDF file with the added form field as a filling template, fill the client data into a corresponding form field according to the form field name through a PDF processing program, and finish the drawing up of the client data customized electronic contract.
Applicants have found that the block-based organization of the text in a PDF file is extremely advantageous for rendering and storage, but is extremely unfriendly for editing. The PDF document is used as a template, a special parameter mark is used at a position where a text needs to be dynamically replaced, a space for replacing the parameter is reserved, then the template is traversed by a program, the parameter is replaced by actual content, and finally the PDF document is electronically signed. This solution can keep the original overall format of the document, but is not friendly to dynamically changing parameter support, such as: the length of the filling parameter content needs to be statically reserved, and a replaced content part may be left blank or covered with other characters, so that a complex table with variable row and column numbers cannot be supported.
In addition, due to the fixed size of the form field, the situation that rendering data is displayed incompletely or empty positions are too much due to the fact that a producer does not estimate the length of the client data improperly in the electronic contract drafting process often occurs, unnecessary legal risks are brought, the phenomenon that the whole contract is seriously split due to the fact that filling data is inconsistent with the text font of the contract also occurs, the reliability of the electronic contract and the willingness of signing of the client are reduced, and the due effect of the electronic contract cannot be played.
(2) The second scheme is as follows: the scheme can relatively support various styles and complex table generation by utilizing the structural flexibility of the HTML document, marking the position needing dynamic change with a special parameter, traversing and replacing the HTML document based on an open-source template engine, converting the HTML document into a PDF document, and finally electronically signing the PDF document. However, applicants have found that there is a large difference in the final document content format (font size, indentation, style and pagination, etc.) from the original version.
In summary, both common solutions have shortcomings and compromise the stringency of the contract documentation.
Therefore, the invention provides a brand-new solution for the existing problems, the scheme directly uses doc document as a template, can ensure the document format, support dynamic complex tables, support direct editing and replacing the document parameter content, write various text styles and furthest ensure the rigor of contract documents.
S300: identifying all preset parameters and positions of the preset parameters in the contract template; the preset parameters are objects for which the contract requesting party needs to dynamically modify the contract template.
In one implementation, the configuration rule of the preset parameters is as follows: the preset parameter uses "$ {" as a start symbol and "}" as an end symbol, and characters between the start symbol and the end symbol are rendering configuration information of the preset parameter. The preset parameters comprise at least one of a text type, a picture type and a table type.
Correspondingly, when a requester user sends a contract signing request, the terminal equipment of the requester user can be operated to input the replacement content according to the requirement, the replacement content is filled into the contract template, and the contract template is dynamically modified to obtain the target electronic contract. Specifically, the substitute content may be text, picture, or table content, and the template rendering is performed by signing the parameter information in the contract request.
S400: and generating a rendering strategy corresponding to the preset parameters.
In the invention, the rendering strategy renders the rendering parameters based on the rendering configuration information.
For the pre-review parameters and rendering strategies of S300-S400, the present invention provides the following examples:
(1) when the preset parameter is a text type, the configuration rule of the preset parameter is as follows:
${@textData|fontSize:A|fontFamily:B|color:C}
wherein "@" indicates that the preset parameter is a text type; "textData" is the filled text; "|" is an attribute separator; "fontSize" is the font size, "A" is the parameter value for the font size; "fontFamily" is the font type, and "B" is the parameter value for the font type; "color" is the font color and "C" is the parameter value for the font color.
In one specific example, the preset parameter rule for text type is "$ { @ textData | fontSize:5| fontFamily: sons | color: red }", where "@" indicates that the parameter type is text, "|" is attribute segmenter, ": "parameter value used later for inputting attribute, fontSize indicates that the font size is 5, fontFamily indicates that the font is song, and color indicates that the font color is red.
The textData represents the filled text content, and specifically, the JSON format is used to represent the text content as follows:
{
"text": alternative content "
}
Rendering strategy for text type: and acquiring a character string of the replacement content through textData in the input parameter information, producing a target character string according to a configured text style, finally calling a software interface for operating a doc file to write the target character string into the position of a preset parameter (the content of "$ { @ textData | fontSize:5| fontFamily: sons | color: red }" as above) of the template, and deleting the preset parameter.
(2) When the preset parameter is a table type, the configuration rule of the preset parameter is as follows:
${#tableData|fontSize:A|fontFamily:B|color:C}
wherein, "#" indicates that the preset parameter is a table type; "tableData" is the table content filled in, including the content information of the ranks; "|" is an attribute separator; "fontSize" is the font size, "A" is the parameter value for the font size; "fontFamily" is the font type, and "B" is the parameter value for the font type; "color" is the font color and "C" is the parameter value for the font color.
In one embodiment, the default parameter rules for the table type are "$ { # tableData | fontSize:5| fontFamily: Song | color: red }". And where "#" indicates that the parameter is a table, "|" is an attribute delimiter, ": "parameter value used later for inputting attribute," fontSize "indicates that the font size is 5," fontFamily "indicates that the font is song font, and" color "indicates that the font color is red.
Wherein, tableData represents the input table content, which contains the information of the line content, and the table content is represented by JSON format as follows:
table type rendering strategy: and acquiring the table parameter content through tableData in the input parameter information. Wherein, title in the parameter information is the name of the table, head is the header data, and rows is the row data information of the table. And the rendering strategy determines the rows and columns of the table according to the field number of the header of the parameter information and the length of the rows list. And filling the fields of each row into the corresponding table. Finally, calling a software interface for operating the doc file to insert the table into the position of the preset parameter (the content of the "$ { # tableData | fontSize:5| fontFamily: Song body | color: red }") of the template, and deleting the preset parameter.
(3) When the preset parameter is a picture type, the configuration rule of the preset parameter is as follows:
${&imgData|higth:A|width:B}
wherein, "&" represents that the preset parameter is a picture type; "imgData" is the picture content filled in; "higth" is the picture height, "a" is the parameter value of the picture height; "width" is the picture width, and "B" is the parameter value of the picture width.
In one embodiment, the picture parameter marking rule is as follows: "$ { & imgData | higth:140| width:140 }", where "&" denotes that the parameter type is picture, "right" and "width" denote that the height and width of the inserted picture are 140x140, respectively.
Wherein imgData is expressed by JSON format as follows:
rendering strategy of picture type: the method comprises the steps of obtaining picture parameter information through imgData in input parameter information, wherein title is a picture title, srcPath is a picture storage position, type is a picture storage format, reading a picture file by a program, setting the length and width of the picture, finally calling a software interface for operating a doc file to insert the picture into the position of a preset parameter (the content of the section of the '$ { & imgData | height: 140| width:140 }') of a template, deleting the preset parameter, and writing the preset parameter into the picture title.
S500: and converting the parameter information into rendering parameters according to the rendering strategy, and filling the rendering parameters into the contract template correspondingly.
In the present invention, the parameter information is converted into rendering parameters according to a rendering policy, and the rendering parameters are filled into a contract template correspondingly, which specifically includes:
s510: acquiring the parameter information;
s520: converting the parameter information into rendering parameters according to the rendering configuration information; wherein the rendering parameters are characters, tables or pictures;
s530: and calling a software interface for operating the word file, correspondingly filling the rendering parameters into the positions of the preset parameters of the contract template, and deleting the preset parameters.
S600: and converting the WORD document filled with the rendering parameters into a PDF file.
S700: and calling the electronic signature service to execute electronic contract signing.
S800: after the electronic contract signing is completed, the electronic contract is persistently stored into a designated file server using FTP or SFTP protocols.
The invention makes a contract template according to the template specification, then stores the contract template in the contract signing server, and makes configuration mapping on the newly generated template and the template type on the contract server for the use of subsequent programs. Aiming at different parameter types, a contract signing system needs to develop corresponding analysis and rendering strategy programs and add the analysis and rendering strategy programs into a rendering flow as required, so that a target electronic contract is dynamically generated according to configuration and input parameters.
The invention provides a generation method of a parameterized template for signing complex electronic contracts. The method supports dynamic complex forms, supports direct editing of the parameter content of the replacement document, supports various text styles, can ensure the format of the contract document, and furthest ensures the rigor of the contract document.
In order to achieve the above object, the present invention provides an electronic contract generating and signing apparatus based on a parameter template, which is used for executing the electronic contract generating and signing method to realize the signing operation of the electronic contract. Specifically, the electronic contract generation signing apparatus based on the parameter template includes:
