Wherein, prior to the step of obtaining variables of predefined different thresholds of action, the multidimensional data based visual variable management method further comprises:
step S11, inputting a variable index, a variable name, a scope and a variable initial value corresponding to the defined variable;
in this embodiment, it should be noted that, the defined variables include a system variable, a global variable and a local variable, where the system variable is a variable shared by all applications in the platform, the global variable is a variable shared in an application, and the local variable is a variable shared in a current page, so that reusability of the variable is improved by the variable of different scope, further, the variable index is a unique identifier of the variable, including letters and numbers, the variable name may be composed of chinese, the scope is an scope of action of the identified variable, global (global variable) or local (local variable) may be selected for identification, one variable corresponds to one scope, the initial value of the variable may be a default value of user-defined input, or may be determined according to other defined variable and expression grammars, for example, the variable "price" is obtained by the product of the variable "per_price" and the variable "total".

and step S13, if the action scope corresponding to the action scope is a global action scope, selecting the application name of the defined variable action.
In this embodiment, if the scope corresponding to the scope is a global scope, an application name to which the variable acts is selected, specifically, if the scope is a global scope, the defined variable is proved to be a global variable, and then the application name to which the global variable acts is selected, so that all pages in the application corresponding to the application name can use the global variable.
Step S14, based on the defined variable, generating a storage identity corresponding to the defined variable;
in this embodiment, based on the defined variable, a storage identity corresponding to the defined variable is generated, specifically, based on the defined variable, the target database will automatically generate a unique storage identity corresponding to the defined variable, so as to facilitate retrieval according to the storage identity.
And step S15, storing the storage identity and the defined variable into a variable information table in a target database.
In this embodiment, it should be noted that, the platform includes at least one application, and each application includes at least one page, and since the variables of different scopes are defined, the platform needs to configure the information table corresponding to the variables for each application.
And storing the storage identity and the defined variable into a variable information table in a target database, specifically, according to the storage identity, performing association storage on the storage identity and the defined variable into a variable information table in a counted target database table, wherein different fields corresponding to different action fields can be preset in order to distinguish the action fields corresponding to the system variable, the global variable and the local variable, for example, system, global and local fields can be used for distinguishing the system variable, the global variable and the local variable.
Step S20, selecting variables to be assigned from the defined variables to assign the variables to be assigned, and obtaining an assignment expression;
in this embodiment, a variable to be assigned is selected from the defined variables to assign the variable to be assigned to obtain an assignment expression, specifically, the variable to be assigned is selected from the variables displayed on a platform page, and then an expression corresponding to the variable to be assigned is filled in to obtain the assignment expression, so that the operation of assigning the variable to be assigned is completed.
The step of selecting a variable to be assigned from the defined variables to assign the variable to be assigned, and obtaining an assignment expression includes:
step S21, selecting the variable to be assigned from the defined variables;
in this embodiment, it should be noted that, when the target user logs in to a certain page, the target user will read the corresponding variable from the target database and display the corresponding variable in the page, that is, display all the variables corresponding to the page.
Selecting the variable to be assigned from the defined variables, specifically selecting the variable to be assigned from the variables displayed in the page, wherein the variables displayed in the page comprise local variables corresponding to the page and global variables corresponding to the page.
Step S23, based on the variable index corresponding to the variable to be assigned, inputting an expression corresponding to the variable to be assigned, and obtaining the assigned expression, wherein the assigned expression comprises expression parameters and operators.
In this embodiment, it should be noted that, the operators include operators such as arithmetic operators, relational operators, logical operators, bit operators, and built-in functions of multidimensional data operations, where the built-in functions include MAX (maximum), MIN (minimum), STRING (converted into character STRING), CONCAT (STRING concatenation) and DAY (time calculation (unit: DAY)), where the STRING function converts an input assignment into a character STRING type, the CONCAT function converts an input assignment into a character STRING form and concatenates the character STRING into a character STRING, and the DAY function accepts an input assignment in a date format and converts the input assignment into a natural DAY.
Based on the variable index corresponding to the variable to be assigned, inputting an expression corresponding to the variable to be assigned to obtain the assigned expression, wherein the assigned expression comprises an expression parameter and an operator, specifically, inputting the expression parameter corresponding to the expression corresponding to the variable to be assigned, wherein a character string can be input as the expression parameter, and all variables except for a self variable in the action domain of the page can be selected as the expression parameter, including a system variable, a global variable and a local variable in the page, and further inputting the operator to complete assignment of the variable to be assigned.
Additionally, the variables in the existing variable system only support simple expressions and calculations, so that the complex business requirements are difficult to fill in and calculate, and business functions supporting multidimensional data operation, such as functions of maximum value, conversion into character strings, character string splicing, nature day calculation and the like, are built in the application, so that the definition and use of the variables can meet the more complex business requirements.
Step S30, debugging and checking the assignment expression to obtain a checking result;
in this embodiment, it should be noted that, when a user enters a certain page of the platform, the user shows that the scope is applied to a variable corresponding to the page and shows that the scope is applied to a variable corresponding to the page, so that the user views the value of the variable in real time, and does not need to manually obtain the value of the variable through breakpoint debugging of the code.
And carrying out debugging and checking on the assignment expression to obtain a checking result, specifically, when the assignment expression corresponding to the variable to be assigned is input, detecting whether the input assignment expression is legal or not, and feeding back checking information to a target user, for example, when the user inputs an illegal expression, prompting an expression grammar error.
After the step of debugging and checking the assignment expression to obtain a checking result, the visualized variable management method based on the multidimensional data further comprises the following steps:
and step B10, if the test result corresponding to the assignment expression is an illegal test result, returning to the execution step: and selecting variables to be assigned from the defined variables to assign the variables to be assigned, and obtaining an assignment expression.
In this embodiment, specifically, if the test result corresponding to the assigned expression is an illegal test result, the illegal assigned expression cannot be resolved and calculated, so that information that the input of the expression is illegal is thrown out, and the execution step is returned: and selecting variables to be assigned from the defined variables to assign the variables to be assigned, and obtaining an assignment expression to carry out assignment again.
Step S40, if the test result is a legal test result, analyzing the assignment expression to obtain a variable analysis result, and storing the variable analysis result into a target database;
in this embodiment, the parsing process is a processing method for calculating a value corresponding to a variable after assignment, and includes a parsing method based on a template engine, a traversing parsing method based on an AST tree (Abstract Syntax Tree, syntax abstract tree), and the like.
If the test result is a legal test result, analyzing the assigned expression to obtain a variable analysis result, and storing the variable analysis result in a target database, specifically, if the test result is a legal test result, firstly, constructing the assigned expression into the grammar abstract tree, further performing recursive computation according to node types corresponding to each node of the abstract grammar tree, where it is required to record expression parameters referenced by a variable to be currently calculated in the assigned expression in each process of recursively computing the variable to determine whether a cyclic reference variable exists in the expression parameters referenced by the variable to be currently calculated, that is, determine whether a self variable exists in the expression parameters corresponding to the variable to be currently calculated, if so, cannot compute the assigned expression, and if not, performing deep recursion computation according to the node types to obtain the variable analysis result, where the node types include data types, operation types, built-in function types, and the like, and the operation types include + - (addition)/(subtraction-! (non) etc., for example, in calculating the valuation expression: a=b+1; when b=a, the value of the variable b needs to be calculated first because the reference variable array corresponding to the expression parameter referenced by the variable a is [ b ], and the reference variable array corresponding to the expression parameter referenced by the variable b is [ a ], the value of the assigned expression cannot be calculated analytically because the variable a references the variable a.
Compared with the technical means for constructing a variable system based on a hard coding mode adopted in the prior art, the embodiment of the application firstly acquires variables with different predefined action thresholds, wherein the variables with different action thresholds comprise variable indexes, variable names, action fields and variable initial values, and then selects variables to be assigned from the defined variables so as to assign the variables to be assigned to obtain an assignment expression, further, debug and test the assignment expression to obtain a test result, further, if the test result is a legal test result, analyze the assignment expression to obtain a variable analysis result, and store the variable analysis result in a target database, thereby realizing the operations of defining the variables with different action fields in a page in a visual mode, improving the reusability of the variables, directly carrying out operations such as assignment and debugging on the defined variables in the page of the platform, namely, carrying out visual custom and use of the variables in the page without source code of the platform, not only reducing the use difficulty of the user, but also overcoming the defect of the source code of the platform, and improving the reusability of the variables in the platform.
Further, referring to fig. 3, based on the first embodiment of the present application, in another embodiment of the present application, the step of analyzing the assignment expression to obtain a variable analysis result if the verification result is a legal verification result, and storing the variable analysis result in a target database includes:
a1, if the test result is a legal test result, converting the assignment expression into an abstract syntax tree;
in this embodiment, it should be noted that the Abstract Syntax Tree (AST) is an abstract representation of the syntax structure of the source code, and represents the syntax structure of the programming language in the form of a tree, and each node on the tree represents a structure in the source code.
If the test result is a legal test result, converting the assignment expression into an abstract syntax tree, specifically, after obtaining the assignment expression corresponding to the variable to be assigned input by the target user, converting the assignment expression into one abstract syntax tree, so as to realize the calculation of the expression through the abstract syntax tree, for example, the abstract syntax tree with the expression of 1× (2+3) can be converted as follows:
and step A20, based on the abstract syntax tree, deeply traversing and calculating node values corresponding to all nodes in the abstract syntax tree to obtain the variable analysis result.
In this embodiment, in the assignment expression process, the built-in functions of the input multidimensional data operation, such as MAX (maximum value), MIN (minimum value), STRING (converted into character STRING), CONCAT (character STRING concatenation), DAY (time calculation (unit: DAY)) and the like, are supported, so that in the parsing process, the calculation of the built-in functions corresponding to the multidimensional data is also supported.
Based on the abstract syntax tree, deeply traversing and calculating node values corresponding to all nodes in the abstract syntax tree to obtain the variable analysis result, specifically, performing recursive calculation according to node types corresponding to all nodes of the abstract syntax tree, returning a value corresponding to a current node if the current node type is a data type, performing recursive calculation according to the value corresponding to the node according to the unitary operator if the current node type is a unitary operator type, and performing calculation according to a function type corresponding to a built-in function if the current node type is a built-in function until the recursive calculation is completed on all nodes of the abstract syntax tree to obtain the variable analysis result.
The step of obtaining the variable analysis result includes:
step A21, judging whether the assignment expression has a cyclic reference variable or not;
in this embodiment, it should be noted that, the cyclic reference variable is that a current variable to be assigned exists in an expression parameter corresponding to the current variable to be assigned, and when the cyclic reference exists in the assignment expression, the value of the calculation assignment expression cannot be resolved, for example, in the calculation assignment expression: a=b+c; b=a; when c=3, calculating the reference variable array of a as [ b, c ], and calculating the values of b and c first, wherein the reference variable array of b is [ a ], the reference variable array of a is updated as [ b, c, a ], and the reference variable array of the variable a has self-variable, and then the existence of the cyclic reference variable is determined.
Judging whether the assignment expression has a cyclic reference variable or not, specifically judging whether the assignment expression corresponding to the current variable has the cyclic reference variable or not.
Step A22, if yes, throwing out illegal information of cyclic reference;
and step A23, if the variable analysis result does not exist, performing recursive calculation according to the node type corresponding to each node of the abstract syntax tree, and obtaining the variable analysis result.
In this embodiment, if the value assignment expression exists, the condition that the value assignment expression exists in the cyclic reference variable is proved, and then the cyclic reference illegal information is thrown out to prompt the target user to assign the value to be assigned again, and further, if the value assignment expression does not exist, recursive calculation is performed according to node types corresponding to all nodes of the abstract syntax tree, and the variable analysis result is obtained.
And step A30, storing the variable analysis result into a variable information table in a target database corresponding to the assignment expression.
In this embodiment, the variable analysis result is stored in a variable information table in a target database corresponding to the assignment expression, and specifically, after calculating an expression value corresponding to the assignment expression, the expression value is stored in the target database corresponding to the variable to be assigned.
The embodiment of the application provides a visual variable management method based on multidimensional data, namely, if the inspection result is a legal inspection result, the assignment expression is converted into an abstract syntax tree, then the node values corresponding to all nodes in the abstract syntax tree are calculated in a depth traversal mode based on the abstract syntax tree to obtain the variable analysis result, and further, the variable analysis result is stored in a variable information table in a target database corresponding to the assignment expression, so that after the defined variable is directly assigned in a page, the assignment expression can be directly analyzed and calculated, more complex service scenes are met, the applicability of a platform is improved, the technical defect that the variable in the platform is low in multiplexing performance because the variable can be defined and used only by knowing the source code of the platform in the prior art is overcome, and the multiplexing performance of the variable in the platform is improved.
