It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without making any creative effort, shall fall within the protection scope of the present application.
Fig. 1 is a flowchart of an application method of a regular expression according to an embodiment of the present application. An embodiment of the present application provides an application method of a regular expression, which may be applied to an application system of a regular expression, where the application system of a regular expression may include an application platform and a server, where the application platform is in communication connection with the server, and as shown in the figure, the application method of a regular expression may specifically include the following steps:
step 11, the application platform obtains the operation type according to the selection of the user; the operation type comprises generating a regular expression, verifying the regular expression or generating a character string according to the regular expression.
The obtaining, by the application platform, the operation type according to the selection of the user may include: after a user enters an application platform, the application platform receives an operation instruction of the user and sends the operation instruction to a server; and after receiving the operation instruction, the server determines the operation type corresponding to the operation instruction and provides the operation type for the application platform.
During implementation, a user selects a required operation type after entering an application platform in a test process, and different operation types and executed subsequent operations are different.
And step 12, if the operation type is to generate a regular expression, the application platform acquires the character string input by the user and sends the character string to the server, and the server generates a corresponding regular expression according to the received character string and feeds the regular expression back to the application platform.
And step 13, if the operation type is the verification regular expression, the application platform receives the regular expression and the character string input by the user and sends the regular expression and the character string to the server, and the server judges whether the received regular expression and the character string are matched and feeds back the judgment result to the application platform.
And 14, if the operation type is that the character string is generated according to the regular expression, the application platform receives the regular expression input by the user and sends the regular expression to the server, and the server generates the corresponding character string according to the received regular expression and feeds the character string back to the application platform.
In this embodiment, the application platform acquires the operation type through selection of the user to perform subsequent operations, and when it is determined that the operation type is the regular expression, the application platform acquires the character string input by the user to send the character string to the server, so that the server can generate the corresponding regular expression according to the input character string, thereby achieving the purpose of generating the regular expression according to the input content of the user; when the operation type is determined to be the verification regular expression, the application platform is used for acquiring the regular expression and the character string input by the user to send the regular expression and the character string to the server, and the server can obtain a verification result by judging whether the input regular expression and the character string are matched or not; when the operation type is determined to be the character string generated according to the regular expression, the application platform is used for acquiring the regular expression input by the user to send the regular expression to the server, and the server generates the corresponding character string according to the received regular expression; therefore, the method meets the requirement of a user for generating the regular expression according to actual needs, is simple in process, and meanwhile supports the user to verify whether the regular expression is matched with the input character string or not and also supports the user to generate the character string according to the regular expression.
The method for generating the regular expression may include various methods, such as machine learning.
In some embodiments, the server may also store a plurality of regular expressions in advance. Such as a regular expression of a mobile phone number, a regular expression of a phone number, a regular expression of an identification number, a regular expression of a mailbox, and the like.
Correspondingly, the application method of the regular expression can further comprise the following steps: the application platform sends an acquisition instruction to the server according to the operation of the user; and the server determines a regular expression corresponding to the acquisition instruction from a plurality of pre-stored regular expressions according to the received acquisition instruction, and feeds the regular expression back to the application platform.
In specific implementation, under the condition that the user selects the operation type to generate the regular expression, the user can select some commonly used regular expressions such as a mobile phone number regular expression on the application platform, only the corresponding regular expression option needs to be selected on the operation platform during operation, then an acquisition instruction which can be acquired by the application platform and is issued by the user is submitted, the acquisition instruction is sent to the server by the application platform, the server can search the corresponding regular expression by using the database after receiving the acquisition instruction, and then the regular expression required by the user is directly returned to the application platform.
In some embodiments, when the server determines whether the received regular expression and the character string match, there may be multiple methods for determining matching, and two of the methods are listed below for description.
The first method comprises the following steps: the server generates a corresponding regular expression according to the received character string, and judges whether the corresponding regular expression is consistent with the received regular expression or not; if the two are consistent, the judgment result is matching; if not, the judgment result is mismatching.
The second method comprises the following steps: the server searches a corresponding character string from the corresponding relation between the pre-stored regular expression and the character string according to the received regular expression, and judges whether the character string in the searched corresponding character string is consistent with the received character string; if the two are consistent, the judgment result is matching; if the two are not consistent, the judgment result is mismatching.
Specifically, the method for judging whether the received regular expression and the received character string are matched by the server may be set according to the requirement, and is not limited here.
After the server obtains the judgment result, if the judgment result is not matched, the server sends the information that the verification fails to pass to the application platform in a voice or text prompting mode, so that the user can know that the verification fails. For example, when the verification fails, the operation interface of the application platform automatically presents a text window, the text content may be "verification failed", the presentation time of the text window may be 2 seconds, and the text window is automatically closed after 2 seconds. Similarly, if the judgment result is matching, the server sends the information that the verification is passed to the application platform in a voice or text prompting mode, so that the user can know that the verification is passed.
