[0003] However, there are many risks in using eval. For the front end, all user input is unreliable. If the eval function is executed on user input, it may cause unpredictable errors. Moreover, this method is suitable for strings with quotation marks, single Quotation marks, backtick literals, and variables of object type cannot get correct calculation results

The invention discloses a data processing method and device, equipment and a storage medium, and relates to the technical field of computers, in particular to the data processing method comprising the steps that a character string input by a user is acquired; the character string is analyzed, data items and operators in the character string are obtained, and the data items comprise at least one of literal quantities and variables; according to the data item and the operator, generating an operation expression according to a preset format; when the operation expression contains the variable, obtaining the value of the variable; and calculating according to the value of the variable and the operation expression to obtain a data processing result of the character string. Therefore, the character string input by the user is analyzed to obtain the corresponding data item and the operator, the operation expression and the value of the variable are obtained according to the preset format and the data item and the operator, and the data processing result is obtained according to the value of the variable and the operation expression. Therefore, calculation of literal quantities with quotation marks, single quotation marks and reverse quotation marks in character strings can be carried out.
Description
technical field [0001] The present application relates to the field of computer technology, and in particular, to a data processing method, device, device, and storage medium. Background technique [0002] In business systems, formulas containing variables are generally calculated using the eval function. The eval function can convert a string into code for execution and return one or more values. [0003] However, there are many risks in using eval. For the front end, all user input is unreliable. If the eval function is executed on user input, it may cause unpredictable errors. Moreover, this method is suitable for strings with quotation marks, single Literal values in quotes and backticks, and variables of object type cannot get correct calculation results. Contents of the invention [0004] The present application provides a data processing method, device, device, and storage medium, which can correctly perform operations on literals with quotation marks, single quo...
