[0002] Local storage data in an application is an important dependent credential for the opening or closing of a function. Taking a browser application as an example, the local storage data of the browser in the browser application includes cookie (data stored on the user's local terminal), sessionStorage (session storage), localStorage (local storage), indexDB (object-oriented database), etc., and localStorage is the data persistently stored in the local browser in particular.

[0003] In the related art, for some functions that depend on local storage data, when they need to be closed in the later stage or in an emergency, a new version needs to be temporarily released to clean up the user's local storage data, which is inefficient.

[0029] Example implementations will now be described more fully with reference to the accompanying drawings. Example implementations may, however, be implemented in many different forms and should not be construed as limited to the implementations set forth herein; rather, these implementations are provided so that this disclosure will be thorough and complete, and will fully convey the scope of example implementations to those skilled in the art.

In the following description, numerous specific details are provided, such as examples of programming, software modules, user selections, etc., to provide a thorough understanding of implementations of the present disclosure. One skilled in the relevant art will recognize, however, that the implementations can be practiced without one or more of the specific details, or with other methods, components, materials, and so forth. Some features, structures, or characteristics can be described as being part of one or more implementations, but can be combined in other implementations. In other instances, well-known features, structures or characteristics have not been described in order to avoid obscuring the concepts of the present disclosure.

[0030] The terms "a," "an," "the," and "said" are used as referring to one or more item / element / part, etc.; the term "comprising" and "having" are used as meaning including, but not limited to, the listed item / element / part, etc.

[0031] In addition, the accompanying drawings are merely schematic and are not intended to be drawn to scale. Identical reference numerals denote like or similar elements throughout the several views, so that repeated description will be omitted. Some of the block diagrams shown in the drawings are functional entities that do not necessarily correspond to physically or logically separate entities.

[0032] Storing data locally in an application is an important dependent credential for turning on or off a function. Taking a browser application as an example, the local storage data of the browser in the browser application includes cookies (data stored on the user's local terminal), sessionStorage (session storage), localStorage (local storage), indexDB (object-oriented database), etc., and localStorage is the data stored persistently in the local browser.

[0033] In the related art, for some functions that depend on local storage data, when they need to be closed in the later stage or in an emergency, a new version needs to be temporarily released to clean up the user's local storage data, and the cleaning efficiency is low.

[0034] In addition, for the local storage data of an application, it also has a size limit, and some historical data may have been abandoned. If it is not cleaned up in time, the user's local storage space will be seriously occupied, so that new data cannot be written, and the normal use of the function is affected.

[0035] To solve the above problems, the present disclosure provides a method and device for cleaning local storage data, which can be applied to Figure 1 the system architecture of the exemplary application environment shown.

[0036] As shown in Figure 1 , the system architecture 100 can include one or more of terminal devices 101, 102, 103, 104, a network 105, and a server 106. The network 105 is used to provide a communication link medium between the terminal devices 101, 102, 103, 104 and the server 106. The network 105 can include various connection types, such as wired, wireless communication links, or optical fiber cables, etc. The terminal devices 101, 102, 103, 104 can be smart phones, tablet computers, notebook computers, desktop computers, etc., but are not limited thereto.

[0037] The terminal device 101, 102, 103, 104 can install an application program, and the terminal device 101, 102, 103, 104 can be understood as a local application program client. The browser application program can run in the browser, and the browser displays the content in the browser application program through the graphical user interface of the terminal device 101, 102, 103, 104, and the browser in the terminal device 101, 102, 103, 104 can be understood as a browser application program client.

[0038] It should be understood that Figure 1 The number of terminal devices, networks and servers in the system is only illustrative. According to the needs of implementation, there can be any number of terminal devices, networks and servers. For example, the server 106 can be a stand-alone physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDNs, and basic cloud computing services such as big data and artificial intelligence platforms.

[0039] The method for cleaning local storage data provided by the embodiments of the present disclosure can be executed in the terminal device 101, 102, 103, 104, and accordingly, the cleaning device for local storage data can be arranged in the terminal device 101, 102, 103, 104.

[0040] The method for cleaning local storage data provided by the embodiments of the present disclosure can also be partially executed in the terminal device 101, 102, 103, 104 and partially executed in the server 106, and accordingly, the cleaning device for local storage data can be partially arranged in the terminal device 101, 102, 103, 104 and partially arranged in the server 106.

[0041] The method for cleaning local storage data provided by the embodiments of the present disclosure can also be executed in the server 106, and accordingly, the cleaning device for local storage data can be arranged in the server 106.

[0042] With the application program being a browser application program, taking the example of displaying the content of the browser application program through the graphical user interface of the terminal device 101, 102, 103, 104, the candidate clearing rule corresponding clearing logic can be configured in the browser application program in advance. When the application developer needs to clear the local storage data of the browser application program client, the application developer can send the clearing rule to the browser application program client based on the browser application program server through the transmission control protocol (TCP). After receiving the clearing rule, the browser application program client can determine the clearing logic corresponding to the clearing rule sent by the browser application program server from the candidate clearing rule corresponding clearing logic, and execute the clearing logic to clear the data of the browser application stored locally by the browser application program client. At the same time, the browser application program client can also record the clearing log corresponding to the clearing operation, and report the clearing log to the browser application program server.

[0043] It is easy for those skilled in the art to understand that the above application scenarios are only for example, and the present example embodiment is not limited thereto.

[0044] Figure 2 The flowchart of the local storage data clearing method in the example embodiment of the present disclosure is shown. The local storage data clearing method provided in the present embodiment can be applied to the client where the application program is located. Referring to Figure 1 The method comprises:

[0045] Step S210, in response to receiving the target clearing rule, determining the clearing logic corresponding to the target clearing rule in the application program;

[0046] Step S220, executing the clearing logic corresponding to the target clearing rule to clear the local storage data of the application program client.

[0047] In Figure 1In the technical solution provided by the embodiment, in response to receiving the target clearing rule, the clearing logic corresponding to the target clearing rule is determined in the application program, and the clearing logic corresponding to the target clearing rule is executed to clear the local storage data of the application program client. Compared with the related art, on the one hand, the disclosure pre-configures the clearing logic of the target clearing rule in the application program, and when local storage data needs to be cleared, the target clearing rule is directly sent to the application program client remotely, so that the application program client can determine the clearing logic corresponding to the target clearing rule in the application program to clear the local storage data, without repeated development and release, and the clearing efficiency of the local storage data can be improved. On the other hand, the disclosure can improve the passive situation of user-side local data management by the active deletion manner, and can effectively and timely manage the user-side local storage data.

[0048] The specific implementation of each step in the embodiment is described in detail as follows: Figure 1 The specific implementation of each step in the embodiment is described in detail as follows:

[0049] In step S210, in response to receiving the target clearing rule, the clearing logic corresponding to the target clearing rule is determined in the application program.

[0050] In an exemplary embodiment, the application program in the disclosure can include one or more of a browser application program and a local application program.

[0051] The browser application program, such as a web (World Wide Web, also known as the World Wide Web) application program, can access the web application program through the web browser of the terminal device, and the web application program is based on an Internet-enabled application program. It can be achieved without downloading the application program and installing it on the terminal device. The browser application program can be developed into a web page using HTML (Hyper Text Markup Language) and CSS (Cascading Style Sheets). The browser application program can be applied to any device that can access the Internet, and does not depend on the operating system used by the device.

[0052] The local application program can be understood as an application program that needs to be installed on the terminal device itself and is developed for a specific mobile operating system. These application programs can be obtained and installed in the application store. That is, the local application program needs to be installed and downloaded to the terminal device to run.

[0053] In an exemplary embodiment, the clearing logic corresponding to the candidate clearing rule can be pre-configured in the application program. The target clearing rule includes one or more of the candidate clearing rules.

[0054] For example, the application developer can configure the application client to implement the candidate cleaning rule corresponding to the cleaning logic for cleaning the local storage data of the application client in the application during the development of the application. The candidate cleaning rule can be customized according to the needs, such as the cleaning rule corresponding to the cleaning method that can be used later.

[0055] In an exemplary embodiment, the candidate cleaning rule includes one or more of cleaning all local storage data of all users, cleaning local storage data of a target user, cleaning all local storage data, cleaning target key value data in the local storage, and cleaning target field data of the target key value in the local storage.

[0056] For example, in the user dimension, the candidate cleaning rule can include cleaning all local storage data of all users (i.e., all application clients) and cleaning local storage data of a target user (i.e., a target application client). The target user can be one or more of all users. In the data dimension, the candidate cleaning rule can include cleaning all local storage data of the application client, cleaning local storage data of the application client indicated by a specified key value, and cleaning local storage data of the application client indicated by a certain field or item in the specified key value.

[0057] In other words, the candidate cleaning rule can include one or more of cleaning all local storage data of all users, cleaning target key value data in the local storage of all users, cleaning target field data of the target key value in the local storage of all users, cleaning all local storage data of a target user, cleaning target key value data in the local storage of the target user, and cleaning target field data of the target key value in the local storage of the target user.

[0058] Of course, the candidate cleaning rule can also be customized according to the needs of the application developer, and can be other cleaning rules that can be used for cleaning the local storage data of the application client later. The exemplary embodiment does not limit the characteristics.

[0059] After the application developer determines the candidate cleaning rule, the application developer can implement the cleaning logic corresponding to the candidate cleaning rule in the application during the development of the application, i.e., configure the program code corresponding to the candidate cleaning rule in the application.

[0060] Since the candidate cleaning rule corresponding cleaning logic is pre-configured in the application, when the application developer wants to delete the local storage data of the application client, the target cleaning rule can be determined from the candidate cleaning rule according to the needs of the application developer, and then the target cleaning rule can be sent to the application client based on the application server. After receiving the target cleaning rule, the application client can determine the cleaning logic corresponding to the target cleaning rule from the application, and then delete the data of the application stored in the local storage of the application client based on the cleaning logic corresponding to the target cleaning rule.

[0061] Exemplary, Figure 3 A flowchart of a method for determining the cleaning logic corresponding to the target cleaning rule in the application is shown in an exemplary embodiment of the present disclosure. Referring to Figure 3 The method can include steps S310 to S320. Wherein:

[0062] In step S310, in response to listening to the transmission control protocol sent by the application server, the target cleaning rule is obtained according to the cleaning rule in the transmission control protocol.

[0063] For example, the application developer can configure a listening function in the application for listening to the target cleaning rule sent by the application server.

[0064] When it is necessary to clean the local storage data of the application client, the application server can broadcast a transmission control protocol to the application client, and the cleaning rule and the user identifier are carried in the transmission control protocol.

[0065] After the application listens to the transmission control protocol sent by the application server, the cleaning rule in the transmission control protocol can be obtained, and the rule is determined as the target cleaning rule.

[0066] The cleaning rule carried in the transmission control protocol is used to indicate which data in the local storage is cleaned, and the user identifier is used to indicate which local storage data in the application client is cleaned.

[0067] Next, in step S320, the cleaning logic corresponding to the target cleaning rule is determined in the application.

[0068] As described above, the cleaning logic corresponding to each candidate cleaning rule is pre-configured in the application, and the application client can determine the cleaning logic code corresponding to the target cleaning rule from the cleaning logic code corresponding to the candidate cleaning rule configured in the application after listening to the target cleaning rule sent by the application server.

[0069] In an exemplary embodiment, the application-related locally-stored data in all application clients can be deleted, or the application-related locally-stored data in specified application clients can be deleted.

[0070] Since the clearing rule is sent to the application clients in a broadcast manner through the transmission control protocol, after receiving the transmission control protocol sent by the application server, the application client can determine whether the application data locally stored by itself needs to be cleared according to the clearing rule in the transmission control protocol.

[0071] Based on this, Figure 4 A flowchart showing another method for determining the clearing logic corresponding to the target clearing rule in an exemplary embodiment of the present disclosure is shown. Referring to FIG. 4, Figure 4 The method can include steps S410 to S440.

[0072] In step S410, in response to receiving the target clearing rule, the target application client indicated by the target clearing rule is determined.

[0073] In step S420, it is judged whether the target application client includes the current application client. If yes, go to step S430, otherwise go to step S440.

[0074] In step S430, in the application of the current application client, the clearing logic corresponding to the target clearing rule is determined.

[0075] In step S440, no processing is performed.

[0076] For example, the target clearing rule can include a clearing type and a user identifier. From the user dimension, in the case of the clearing type being to clear the locally-stored data of all application clients, the user identifier can be empty. At this time, any application client receiving the target clearing rule can be understood as the target application client. From the user dimension, in the case of the clearing type being to clear the locally-stored data of specified application clients, the value of the user identifier can be the identifier corresponding to the application client whose locally-stored data is to be cleared.

[0077] Based on this, after the application client receives the target clearing rule, the target application client indicated by the target clearing rule can be determined according to the clearing type. Specifically, in the case where the clearing type is clearing all local storage data of the application client, it can be determined that the current application client itself is the target application client, i.e., the current application client receiving the target clearing rule can determine that the target application client includes itself; in the case where the target clearing rule is clearing local storage data of a specified application client, each application client receiving the target clearing rule can continue to acquire the user identifier in the target clearing rule, and match the user identifier in the target clearing rule with the user identifier of itself. If the matching is successful, it is determined that the target application client includes itself, otherwise, it is determined that the target application client does not include itself.

[0078] In the case where the application client receiving the target clearing rule determines that the target application client includes itself, the application client can determine the clearing logic corresponding to the target clearing rule in the application, otherwise, the application client can not perform any processing and continue to listen to the transmission control protocol sent by the application server.

[0079] Through the above steps S410 to S420, the local storage data in the specified application client can be actively deleted, and the accuracy of clearing the local storage data is improved.

[0080] Next, in step S220, the clearing logic corresponding to the target clearing rule is executed to clear the local storage data of the application client.

[0081] For example, in the case where the application client receiving the target clearing rule determines that the target application client includes itself, the application client can execute the clearing logic corresponding to the target clearing rule included in the application, so as to clear the data of the application stored in itself. That is, in the case where the current application client is the target application client, the current application client executes the clearing logic corresponding to the target clearing rule to clear the local storage data of the current application client.

[0082] In an exemplary embodiment, in the case where the application includes a browser application, the application client includes a browser application client, which is self-explanatory, i.e., the application takes the browser as the client. In the case where the application includes a local application, the application client can include a local application client, which is self-explanatory, i.e., the application needs to be downloaded and installed on the terminal device, and the terminal device is taken as the client.

[0083] In an example embodiment, the application client records log information of an operation instruction of the cleaning logic corresponding to the target cleaning rule, and sends the log information to the application server.

[0084] For example, the application client can record log information corresponding to the operation of the cleaning logic corresponding to the target cleaning rule, and then report the log information to the application server. In this way, the compliance and security of the cleaning process of the local storage data of the application client can be ensured, and the tracking in the future can be facilitated.

[0085] Figure 5 A flowchart of another method for cleaning local storage data in an example embodiment of the present disclosure is shown. The method for cleaning local storage data can be applied to an application server. Referring to Figure 5 , the method can include steps S510 to S520.

[0086] In step S510, a target cleaning rule is sent to an application client, so that the application client executes the cleaning logic corresponding to the target cleaning rule;

[0087] In step S520, log information corresponding to the cleaning operation of the local storage data sent by the target application client is received.

[0088] For example, when the application developer needs to clean the local storage data of the application client, the application server can broadcast a transmission control protocol to the application client, and the transmission control protocol carries a target cleaning rule. After listening to the transmission control protocol sent by the application server, the application client can determine the target cleaning rule from the transmission control protocol, and then determine the cleaning logic corresponding to the target cleaning rule from the cleaning logic corresponding to the candidate cleaning rule pre-configured in the application, and then execute the cleaning logic to clean the related data of the application stored locally by the application client. When cleaning the local storage data, the application client can record log information corresponding to the cleaning operation, and report the log information to the application server.

[0089] Among them, Figure 5 The specific details of the method for cleaning local storage data shown can refer to the method for cleaning local storage data shown in the above Figure 2 , which will not be described here.

[0090] Next, taking a browser web application as an example, Figure 6 A flowchart of another method for cleaning local storage data in an example embodiment of the present disclosure is shown. Referring to Figure 6The method can include steps S610 to S640. In step S610, the candidate clearing rule corresponding clearing logic is configured in advance in the browser application; in step S620, the browser application program server sends a transmission control protocol to the browser application program client; in step S630, the browser application program client executes the clearing logic corresponding to the clearing rule in the transmission control protocol to clear the local storage data when the transmission control protocol is listened to; in step S640, the browser application program client records the log information corresponding to the clearing process and sends the log information to the browser application program server.

[0091] For example, when developing a web application, the clearing logic code corresponding to the candidate clearing rule can be configured in the web application. When it is necessary to clear the browser local storage data, the server can issue a TCP protocol to the client, and the protocol content can include the clearing rule and the user information to be cleared. After the client listens to the TCP protocol, the client can execute the clearing logic corresponding to the clearing rule in the TCP protocol to clear the current local storage data. Meanwhile, the client can record and report log information during the clearing process.

[0092] According to the local storage data clearing method of the present disclosure, only the clearing logic code corresponding to each clearing rule needs to be configured in the application program client during development, and subsequent remote clearing of the local storage data of the application program client can be implemented without the need to release a new version or repeat development, thereby improving the efficiency of local storage data clearing. The passive situation of user-side local storage data management can be improved, and the user-side local storage data can be actively and accurately managed.

[0093] Those skilled in the art can understand that all or part of the steps of the above-mentioned embodiments are implemented as a computer program executed by a CPU. When the computer program is executed by the CPU, the above-mentioned functions defined by the above-mentioned method provided by the present application are executed. The program can be stored in a computer readable storage medium, which can be a read-only memory, a magnetic disk or an optical disk, etc.

[0094] In addition, it should be noted that the above-mentioned figures are only schematic illustrations of the processes included in the method according to the exemplary embodiments of the present application, and are not for limiting purposes. It is easy to understand that the processes shown in the above-mentioned figures do not indicate or limit the time sequence of these processes. In addition, it is also easy to understand that these processes can be executed synchronously or asynchronously, for example, in multiple modules.
