With continued reference to FIG. 1, a flow 100 of some embodiments of a method of code-less page printing according to the present disclosure is shown. The code-free page printing method comprises the following steps:

step 101, constructing a data processing service flow.

In some embodiments, the executing body (e.g., a computing device) of the codeless page printing method may construct the data processing traffic flow described above. Wherein the data processing service flow is an automated data processing flow. The data processing service flow comprises at least one data operation node. The data operation node is a node for operating data.

As an example, the executing entity may automatically perform automatic connection on an operation node in the at least one data operation node to generate the data processing traffic flow.

It should be noted that the computing device may be hardware or software. When the computing device is hardware, it may be implemented as a distributed cluster composed of multiple servers or terminal devices, or may be implemented as a single server or a single terminal device. When the computing device is embodied as software, it may be installed in the hardware devices enumerated above. It may be implemented, for example, as multiple software or software modules to provide distributed services, or as a single software or software module. And is not particularly limited herein. It should be understood that the number of computing devices may have any number of computing devices, as desired for an implementation.

Optionally, the node types of the data operation node may include: the data reading node type, the data operation node type and the data branch judgment node type. The data reading node type represents that the data operation node is a node for reading data from a data source. Wherein the data source is used for storing data. For example, the data source may be, but is not limited to, any of: mySQL database, postgreSQL database, access data table, neo4j database. The data operation node type represents that the data operation node is a node for processing data. For example, a data manipulation node may be used for data type conversion of data. The data branch judgment node type represents a data operation node for data branch judgment.

Optionally, the node type of the first data operation node of the data processing service flow is the data reading node type.

In some optional implementations of some embodiments, the constructing a data processing service flow by the execution subject may include:

firstly, determining a data operation node selected by a service flow arranging user on a service flow arranging interface to obtain the at least one data operation node.

The service flow arranging user may be a user for arranging the data processing service flow. The service flow arrangement interface may be an interface for the service flow arrangement user to arrange the data processing service flow.

As an example, the service flow orchestration interface may be as shown in fig. 2, where the service flow orchestration interface shown in fig. 2 includes a node selection module 201, a service flow orchestration module 202, and a rule configuration module 203. The node selection module 201 is configured to provide a data operation node that can be dragged and moved to the service flow orchestration user. As shown in fig. 2, the data operation node may include: the system comprises a data reading node, a data operation node, a data branch judging node, a data circulation judging node and a data selection judging node. The service flow arrangement module 202 is configured to display the data processing service flows arranged by the service flow arrangement user in real time. The rule configuration module 203 is used for arranging configuration information corresponding to the data operation node set by the user through the service flow. For example, the rule configuration module 203 displays an input box of a data branch judgment expression corresponding to the "data branch judgment node". For example, the data operation node may include the following functions: variable calculation, service calling, cache operation, cache reading, back-end calling, decision tables and the like.

And secondly, determining the operation relationship among the data operation nodes in the at least one data operation node to obtain an operation relationship information set.

And the operation relation information in the operation relation information set represents the operation sequence between the data operation nodes. The operation relation information can be formed by connecting lines of nodes among data operation nodes set in the service flow arrangement interface by the service flow arrangement user.

As an example, the operation relationship information may be [ data operation node a, data operation node B ], and data processed by the data operation node a is represented to flow to the data operation node B, so that the data operation node B further performs data processing.

And thirdly, determining operation logic information corresponding to each data operation node in the at least one data operation node to obtain an operation logic information set.

And the operation logic information in the operation logic information set represents the data processing rule of the corresponding data operation node.

Optionally, the determining, by the executing entity, operation logic information corresponding to each data operation node in the at least one data operation node may include the following sub-steps:

and a first substep, in response to the node type of the data operation node being a data reading node type, determining data reading rule information configured by the service flow arrangement user on the service flow arrangement interface as operation logic information corresponding to the data operation node.

The data reading rule information may include, but is not limited to: the address corresponding to the data source, the data screening condition, etc.

And a second substep, in response to determining that the node type of the data operation node is a data operation node type, determining data operation rule information configured on the service flow arrangement interface by the service flow arrangement user as operation logic information corresponding to the data operation node.

The data operation rule information may represent a combination rule of the data.

As an example, data A may be "length of work" (units: hours) and data B may be "salary". The data combination rule may be: data C = data a × data B.

And a third substep, in response to determining that the node type of the data operation node is a data branch judgment node type, determining branch judgment rule information configured by the service flow arrangement user on the service flow arrangement interface as operation logic information corresponding to the data operation node.

Wherein the branch judgment rule information characterizes an execution condition of the branch.

As an example, the packet judgment rule information may be [ data < M, execution branch a; data ≧ M, branch B is executed. Where M may be a manually set cut point.

And fourthly, generating the data processing service flow according to the at least one data operation node, the operation relation information set and the operation logic information set.

As an example, the executing body may perform node connection on a data operation node in the at least one data operation node according to the running relationship information set, and use operation logic information corresponding to the data operation node as a configuration file of the data operation node.

And step 102, sequentially operating data operation nodes in at least one data operation node included in the data processing service flow to generate a data information sequence to be printed.

In some embodiments, the execution subject may automatically run data operation nodes in at least one data operation node included in the data processing service flow in sequence to generate the data information sequence to be printed. Wherein, the data information sequence to be printed can be data to be printed.

And 103, configuring a page template according to the information sequence of the data to be printed to generate a candidate page template.

In some embodiments, the execution body may configure the page template according to the information sequence of the data to be printed, so as to generate a candidate page template. The candidate page template may be a page template corresponding to the data information sequence to be printed.

As an example, the executing body may automatically lay out the data information to be printed in the data information sequence to be printed to generate a candidate page template.

In some optional implementation manners of some embodiments, the configuring, by the execution main body, the page template according to the data information sequence to be printed to generate the candidate page template may include:

firstly, acquiring a prefilled text information set inserted by the service flow arranging user on a page template setting interface.

The page template setting interface is an interface used for configuring the page template. The pre-filled text information in the pre-filled text information set comprises: pre-filled text content, pre-filled text position, and pre-filled text format information. The pre-filled text information includes pre-filled text content that characterizes pre-filled and fixed text content within the page. The prefilled text position represents a position of the prefilled text content in the page template. The pre-filled text format information characterizes a text format of the pre-filled text content. For example, the pre-filled text format information may be [ font: song body, character size: number four, text style: and the font is bolded ].

And secondly, generating a blank page template.

The page size of the blank page template can be manually set. For example, the page size of the blank page template may be A4. The page size of the blank page template may also be A5.

Thirdly, for each pre-filled text message in the pre-filled text message set, executing the following text operation steps:

the first substep, according to the pre-filled text format information included in the pre-filled text information, format adjustment is carried out on the pre-filled text content.

As an example, the pre-filled text content may be "examination order number", and the pre-filled text format information may be [ font: song dynasty, word size: number four, text style: and the font is bolded ]. The style of the content "examination and approval sheet number" of the pre-filled text after format adjustment is as follows: font: song dynasty, word size: number four, text style: the font is bolded.

And a second substep, filling the pre-filled text content with the adjusted format into the blank page template to generate a page template filled with the pre-filled text.

And filling the position of the pre-filled text content with the adjusted format in the blank page template is the same as the position of the pre-filled text included in the pre-filled text information.

Fourthly, for each piece of data information to be printed in the data information sequence to be printed, executing the following data filling processing steps:

the first substep is to determine the filling position of the data corresponding to the data information to be printed in the page template filled with the pre-filled text.

The execution main body may determine a filling position corresponding to the data information to be printed, which is set on a page template setting interface by the service flow arrangement user, as the filling position corresponding to the data information to be printed.

And a second substep of adjusting the length of the filling bit according to the data length corresponding to the data information to be printed.

As an example, the data length corresponding to the data information to be printed may be 20 characters. The pad bit length of the pad bits can be adjusted to 20 characters.

And fifthly, determining the page template processed by the data filling processing step as an initial page template.

And sixthly, in response to the fact that the service flow arranging user finishes the template adjustment of the initial page template on the page template setting interface, determining the initial page template after the template adjustment as the candidate page template.

And the service flow arranging user manually adjusts the position of the content included by the initial page template on the page template setting interface.

As an example, a schematic diagram of a page template setting interface as shown in fig. 3, where the page template setting interface includes: a function block 301 and a candidate page template 302. The function module 301 includes functions for setting a page template, such as a "reset" function, a "clear style" function, a "delete" function, a "paste" function, a "copy" function, a "background setting function, a" canvas setting "function, a" paper size "function, a" margin "function, and a" set "function. The candidate page template 302 includes "X.. X" as the formatted pre-filled text content, e.g., "xxxxxxxx" as the font-bolded pre-filled text content included in the candidate page template 302. The candidate page template 302 includes a rectangular frame as a filling bit corresponding to the data information to be printed.

And 104, responding to the condition that the target printing device calls the candidate page template for page printing, and performing printing authentication on the target printing device and the target user to generate page template use authority information.

In some embodiments, the execution body may perform print authentication on the target printing device and the target user to generate page template usage rights information in response to the presence of the target printing device calling the candidate page template for page printing. Wherein the target user is a user using the target printing apparatus. The page template use authority information represents whether the target user is allowed to call the candidate page template by using the target printing device. The target printing apparatus may be an apparatus for page printing. For example, the target printing device may be a printer.

As an example, the execution main body may generate the page template usage right information by determining whether the target user has a usage right to the target printing apparatus and determining whether the target user has a usage right to the candidate page template.

In some optional implementations of some embodiments, performing print authentication on the target printing device and the target user to generate the page template usage right information may include the following steps:

first, whether the target user has the use authority of the target printing device is determined.

Wherein, the executing body may refer to the printing apparatus usage right data table to determine whether the target user has the usage right to the target printing apparatus. The above-mentioned printing apparatus usage authority data table is a data table in which usage authority of a user for the printing apparatus is recorded.

As an example, the target printing device may be "printing device a". The target user may be "user a". One record in the above-described device usage authority data table may be "printing device a, available user list: [ user A, user B, user C ] ". Since "user a" belongs to the usable user list corresponding to "printing apparatus a", thereby "user a" has a use right to "printing apparatus a".

And a second step of, in response to determining that the target user has the right of use for the target printing apparatus, executing the following print authentication processing steps:

the first substep, confirm the above-mentioned operational data source of target user, get the operational data source set.

And the operable data source in the operable data source set is a data source which can be operated by the target user. The data source is used for storing data. For example, the data source may be, but is not limited to, any of the following: mySQL database, postgreSQL database, ACCESS data sheet, neo4j database.

And a second substep, in response to determining that the data information to be printed in the data information sequence to be printed all belong to data included in the operable data source set and that a target user has a read-write permission for the data information sequence to be printed, generating page template use permission information representing that the target user is allowed to use the target printing device to call the candidate page template.

And a third substep, in response to determining that there is data information to be printed in the data information sequence to be printed, which is not included in the operable data source set, or that the target user does not have the read-write permission for the data information sequence to be printed, generating page template use permission information representing that the target user is not allowed to use the target printing device to call the candidate page template.

A fourth substep, in response to determining that the target user does not possess the usage right to the target printing device, generating page template usage right information characterizing that the target user is not allowed to use the target printing device to invoke the candidate page template.

And step 105, in response to the fact that the representation of the page template use permission information allows the target user to use the target printing device to call the candidate page template, injecting the data information to be printed in the data information sequence to be printed into the candidate page template to generate the page to be printed.

In some embodiments, the execution subject injects the data information to be printed in the data information sequence to be printed into the candidate page template to generate the page to be printed in response to determining that the representation of the page template usage right information allows the target user to invoke the candidate page template using the target printing device.

In some optional implementation manners of some embodiments, the injecting, by the execution main body, the to-be-printed data information in the to-be-printed data information sequence into the candidate page template to generate a to-be-printed page may include the following steps:

and step one, injecting data corresponding to the data information to be printed into corresponding filling bits in the candidate page template for each data information to be printed in the data information sequence to be printed.

And step two, in response to the completion of the injection of the data information to be printed in the data information sequence to be printed, determining the candidate page template after the injection as a candidate page.

And thirdly, dynamically adjusting the data line spacing of the candidate page according to the pre-filled text content set and the to-be-printed data information sequence included by the candidate page to generate the to-be-printed page.

First, the execution body may determine an average distance between the pre-filled text content set and the data information sequence to be printed included in the candidate page. Then, the executing body may perform data line spacing dynamic adjustment on the candidate page according to the average spacing to generate the page to be printed.

And 106, setting a dot-shaped texture watermark in the page to be printed.

In some embodiments, the execution main body may set the dot-like texture watermark in the page to be printed in various ways. The dot-shaped grain watermark is generated according to the data information sequence to be printed.

In some optional implementation manners of some embodiments, the setting, by the execution main body, a dot-shaped grain watermark in the page to be printed may include the following steps:

firstly, determining the line number contained in the page to be printed to generate line number information.

The line number information represents the line number contained in the page to be printed.

As an example, the above-described page to be printed may contain 30 lines of data. The line number information is "30 lines".

And secondly, carrying out watermark address positioning according to the line number information to generate watermark position information.

And the watermark position information represents the line position of the dotted filling watermark.

As an example, the execution subject may generate the watermark location information by address hashing the line number information. For example, the above-mentioned line number information may be "30 lines". Watermark location information = 30%. For example, K may be "7", and the watermark location information is "2 lines".

And thirdly, determining the character quantity included in the line position corresponding to the watermark position information.

The execution main body may determine the amount of characters included in the line position corresponding to the watermark position information included in the page to be printed.

By way of example, line 2 of the page to be printed comprises 50 characters.

And fourthly, carrying out hash processing on the character quantity to generate a hash value.

Where the hash value = character amount% S. Where S may be a manually set numerical value. For example, S may be "8" and the hash value may be "2".

Fifthly, for each character included in the data in the line position corresponding to the watermark position information, executing the following step of setting the dot-shaped grain watermark:

the first substep, confirm the pixel number that the above-mentioned character occupies.

As an example, the number of pixels occupied by a character may be 300.

And a second substep, performing pixel sampling processing on the number of the pixels to generate the number of sampling pixels.

The execution main body can determine the product value of the preset sampling proportion and the number of the pixel points as the number of the sampling pixel points.

As an example, the predetermined sampling ratio may be 80%, and the number of sampling pixels may be 240.

And a third substep of determining the sum of the number of the sampling pixels and the hash value as the number of the inking points corresponding to the character.

As an example, the number of sampling pixels may be 240. The hash value may be 2. The number of the inked dots is 242.

And a fourth substep of redrawing the character according to the number of the impact points.

Wherein the execution body redraws the characters in dot form according to the number of the inked dots. The character after the character redrawing is a dot character. The number of dots in the dot character is the same as the number of the above-described inked dots.

And a sixth substep, determining the character after the character redrawing as the sub-dot-shaped line watermark in the dot-shaped line watermark.

Optionally, the execution main body may scan the page to be printed provided with the dot-shaped texture watermark. First, the first step and the second step are repeatedly executed, then the number of the inked points obtained by scanning is compared with the number of the inked points obtained by the third substep, and when the numbers are consistent, the paper document is determined not to be falsified. And when the inconsistency is not consistent, the paper document is judged to be tampered.

The content in the step 106 is an inventive point of the present disclosure, which solves the third technical problem mentioned in the background art, that is, "the conventional invisible watermark is often only applicable to electronic pages, but not to paper pages". In practical situations, watermarks are widely applied to page anti-counterfeiting as an effective anti-counterfeiting means. Because the invisible watermark can not damage the content of the page, the readability of the page is greatly improved compared with the readability of the dominant watermark. However, for paper documents, because the invisible watermark cannot be embedded into the paper documents, the invisible watermark cannot be adopted to effectively protect the paper documents. Based on this, the present disclosure proposes a dot-like grain watermark. Firstly, the adding position of the dot-shaped grain watermark in the page to be printed is determined through watermark address positioning. Because the determination of the adding position depends on the line number contained in the page to be printed, different pages have different watermark adding positions, and the flexibility of watermark setting is improved. And then, character redrawing is carried out on the character in a dot-like inking mode by combining the hash value and the number of the inking points obtained by sampling the number of the pixel points. So that the watermark with dot-shaped grains is hidden in the character. And meanwhile, the readability of the page is not influenced. By the method, the paper document is prevented from being tampered and protected.

And step 107, printing the page to be printed with the dot-shaped texture watermark.

In some embodiments, the execution main body may print a page to be printed with a dot-like watermark. The execution main body can control the target printing equipment to print the page to be printed provided with the dot-shaped grain watermark. Wherein the target printing device may be a printer.

The above embodiments of the present disclosure have the following advantages: by the code-free page printing method of some embodiments of the disclosure, the applicability of page printing is improved, and the readability of the page is improved. The reasons for the poor suitability of page printing and poor page readability in particular are: firstly, when the types of contained data are more and the requirements on output forms are more, the mode of generating the document containing the data is poor in applicability; second, conventional explicit watermarks often cover the data in the page to some extent, thereby affecting the readability of the page. Based on this, the code-free page printing method of the present disclosure first constructs a data processing service flow, wherein the data processing service flow includes at least one data operation node. The automatic process construction of the same kind of data is realized by constructing a data processing service flow. And then, sequentially operating the data operation nodes in at least one data operation node included in the data processing service flow to generate a data information sequence to be printed. And realizing the acquisition and generation of the data to be printed by operating the data processing service flow. Further, according to the information sequence of the data to be printed, a page template is configured to generate a candidate page template. Thus, the applicability template corresponding to the data to be printed is generated. Thereby facilitating subsequent multiple use. In addition, in response to the target printing device calling the candidate page template for page printing, performing printing authentication on the target printing device and a target user to generate page template usage right information, wherein the target user is a user using the target printing device, and the page template usage right information represents whether the target user is allowed to use the target printing device to call the candidate page template. The target user and the target printing equipment are subjected to printing authentication, so that the problem of low data security caused by direct printing is solved when the data to be printed are sensitive. In addition, in response to determining that the representation of the page template use permission information allows the target user to use the target printing device to call the candidate page template, injecting the data information to be printed in the data information sequence to be printed into the candidate page template to generate a page to be printed. Further, a dot-shaped line watermark is arranged in the page to be printed, wherein the dot-shaped line watermark is generated according to the data information sequence to be printed. And generating the dot-shaped texture watermark corresponding to the data to be printed through the data to be printed, thereby ensuring the uniqueness of the watermark. Compared with the traditional dominant watermark (such as a graphical dominant watermark and a text dominant watermark), the dot-shaped grain watermark can reduce the coverage of data in the page and improve the readability of the page. And finally, printing the page to be printed with the dot-shaped texture watermark. By the method, the applicability of page printing is improved, and the readability of the page is improved.
