Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
With the wide application of terminal devices (such as mobile phones, notebook computers, tablet computers, etc.), more and more applications are installed on the terminal devices. Taking a terminal device for installing an IOS system as an example, the IOS system adopts a sandbox mechanism, that is, an application program installed under the IOS system can only read and write files in a file system created for the application program, and can not access other file systems, where such a file system is a sandbox, and all non-code files (such as images, audio, configuration files, text files, etc.) are stored in the sandbox. More visually, each application has its own storage space, and cannot flip over its own wall to access the contents of the storage space of another application. It should be noted that, when an application is installed and executed on a terminal device, data (also referred to as cache data) stored in a sandbox for improving the running rate of the application or helping the application to implement some function is usually generated. If the cache data cannot be cleaned in time, a large amount of storage space in the terminal equipment is occupied, and normal use of the terminal equipment is affected. Therefore, it is important to perform timely and efficient cleaning of the buffered data. Aiming at the problem that the cache data cannot be cleaned by the prior data cleaning operation initiated by a user, the embodiment of the application provides a data cleaning method based on a sandbox.
Fig. 1 is a flowchart of a sandbox-based data cleaning method according to an embodiment of the present application, where the method is applied to a setting application program in a user terminal, and the setting application program is communicatively connected to a target application program running by using a sandbox mechanism, and as shown in fig. 1, the method includes:
step 101, establishing a communication connection with a server.
Step 102, receiving a data cleaning instruction sent by a server, wherein the data cleaning instruction comprises an identification of a target application program and data storage paths to be cleaned, and the server sends the data cleaning instruction based on the cache data quantity under each data storage path in a sandbox corresponding to the target application program, which is acquired in real time.
And step 103, based on the identification of the target application program, sending a data cleaning instruction to the target application program so that the target application program cleans the cache data under the data storage path to be cleaned.
In practical application, because the setting application program in the user terminal and the target application program running by adopting the sandbox mechanism are in communication connection in advance, in order to enable the data cleaning instruction of the subsequent server to be smoothly sent to the target application program, the application establishes communication connection between the setting application program and the server. The setting application may be understood as an application or service running on the user terminal, which is capable of establishing a long link with the server, and receiving and transmitting commands. The target application may be any third party application installed on the user terminal, such as WeChat, QQ, etc., which are not listed herein.
In the implementation process, the server can acquire the cache data amount under each data storage path in the sandbox corresponding to the target application program in real time, and send a data cleaning instruction to the set application program based on the cache data amount under each data storage path in the sandbox, wherein the data cleaning instruction comprises the identification of the target application program and the data storage path to be cleaned. The setting application program determines a target application program based on the identification of the target application program, and sends a data cleaning instruction to the target application program, so that the target application program cleans the cache data under the data storage path to be cleaned.
Here, it should be noted that, since the server may communicate with the setting application through the first data protocol, and the setting application may communicate with the target application through the second data protocol, the first data protocol communication is different from the second data protocol communication, and in this case, if the data cleaning instruction is directly sent to the target application, there may be a case that the target application cannot recognize the data cleaning instruction. In view of this, in the present application, after the application program is set to receive the data cleaning instruction sent by the server, format conversion packaging is performed on the data in the data cleaning instruction, and after the target application program receives the data cleaning instruction, data analysis is performed on the data cleaning instruction after format conversion packaging, so as to obtain the cache data under the data storage path to be cleaned.
In addition, because sandboxes corresponding to the apps are isolated from each other under the IOS system, the sandboxes allocated to the current App by the system cannot be accessed by the outside. In the implementation, the setting application program is matched with the SDK for use, and in particular, because some mechanisms in the SDK can interact with the setting application program, the setting application program can control and clear the sandboxed file of the target application program, namely, the setting application program sends a data clearing instruction to the SDK, and the SDK directly executes the data clearing operation after receiving the data clearing instruction.
In this embodiment, the step of setting the application program to establish a communication connection with the target application program includes: receiving a communication identification code sent by a target application program; if the communication identification code is the preset identification code for establishing communication connection, returning a receipt identification code corresponding to the communication identification code to the target application program so as to establish communication connection between the set application program and the target application program.
In the implementation, the User Datagram Protocol (UDP) ports are set for both the set application program and the target application program. When the user terminal starts the target application, a communication identification code with a unique identification for establishing a communication connection is generated and broadcasted. When the UDP port of the set application program monitors the communication identification code, the set application program can determine that the communication identification code is used for establishing communication connection through the communication identification code with the unique identification, and then the set application program returns a receipt identification code corresponding to the communication identification code to the target application program. At this time, the UDP port of the target application is also in a listening state, and after receiving the receipt identifier, the setting application and the target application establish a communication connection smoothly.
According to the sandbox-based data cleaning method provided by the embodiment of the application, the communication connection between the set application program and the server is established, the data cleaning instruction sent by the server based on the cache data quantity under each data storage path in the sandbox corresponding to the target application program obtained in real time is received, and then the data cleaning instruction is sent to the target application program based on the identification of the target application program, so that the target application program can clean the cache data under the data storage path to be cleaned, namely, a user does not need to manually initiate the data cleaning instruction, the server can automatically clean the cache data according to the cache data quantity under each data storage path in the sandbox corresponding to the target application program obtained in real time, and the cleaning efficiency and accuracy are higher.
In an embodiment of the present application, the method further includes: receiving the cache data quantity under each data storage path in the sandbox corresponding to the target application program; the data storage paths of the sandboxes are used for storing data, wherein the cache data quantity under each data storage path in the sandboxes is detected by the SDK in real time; and sending the cached data quantity under each data storage path in the sandbox and the identification of the target application program to the server.
In practical application, the target application program can acquire the cache data volume under each data storage path in the sandbox at regular time or in real time, and send the cache data volume to the setting application program, and then send the cache data volume to the server through the setting application program for reference by a developer or the server, and then issue more accurate data cleaning instructions through the server.
Specifically, as an implementation manner, after the server receives the amount of cache data under each data storage path in the sandbox sent by the target application program, the amount of cache data under each data storage path may be compared with a preset threshold, and if the amount of cache data under a certain data storage path is greater than the preset threshold, the server directly issues a data cleaning instruction to the set application program, so as to clean the cache data under the data storage path.
As another implementation manner, after the server receives the amount of the buffered data under each data storage path in the sandbox sent by the target application program, the developer may compare the amount of the buffered data under each data storage path with an empirical value or a preset threshold value, and if the amount of the buffered data under a certain data storage path is greater than the empirical value or the preset threshold value, the developer controls the server to issue a data cleaning instruction to the set application program, so as to clean the buffered data under the data storage path.
It should be noted that, the setting application program in the present application may uniformly receive and send commands to a plurality of application programs to implement a multi-application group control scenario. Specifically, for example, the setting application program receives the amount of cache data under each data storage path sent by the plurality of target application programs, and the server may issue different data cleaning instructions to different target application programs through the setting application program according to the amount of cache data under each data storage path of each target application program, where the data cleaning instructions include the identification of the target application program, so that the data cleaning instructions can be accurately sent to each target application program.
In the embodiment of the application, in order to facilitate the developer to accurately know the cleaning result of the target application program, the method further comprises the following steps: receiving data cleaning result information sent by a target application program; and sending the data cleaning result information to a server.
For the data cleaning result information, for example, if the size of the cached data amount under the current data storage path in the sandbox does not reach the threshold value, the data cleaning result information is "not cleaned" and is accompanied by a reason for not cleaning (for example, the size of the cached data amount does not reach the threshold value); if the size of the cached data in the current data storage path in the sandbox exceeds the threshold, the data scrubbing result information is "scrubbed" with the reason for scrubbing attached (e.g., the size of the cached data exceeds the threshold).
In summary, the sandbox-based data cleaning method provided by the embodiment of the application can clean the cache data in the sandbox in real time, has strong instantaneity, can clean the data under the condition of not affecting the function of the target application program, and specifically can clean the cache data corresponding to the unused function according to the current use condition of the target application program by manually checking the cache data in each data storage path in the sandbox. In addition, the application supports unified integration of a plurality of target application programs of the same user terminal, does not need to add an API interface to the target application programs, and improves the working efficiency. By monitoring the cache data volume of a plurality of target application programs in the same user terminal, the purposes of timely cleaning and early warning can be achieved.
Fig. 2 is a schematic diagram of another sandbox-based data cleaning method according to an embodiment of the present application, where the method is applied to a target application running in a user terminal by using a sandbox mechanism, and the target application is communicatively connected to a set application in the user terminal, as shown in fig. 2, and the method includes:
step 201, receiving a data cleaning instruction sent by a setting application program, wherein the data cleaning instruction comprises an identification of a target application program and a data storage path to be cleaned, and the data cleaning instruction is sent to the setting application program by a server based on the cache data amount under each data storage path in a sandbox corresponding to the target application program acquired in real time.
Step 202, cleaning cache data under a data storage path to be cleaned.
The server acquires the cache data amount under each data storage path in the sandbox corresponding to the target application program in real time, and sends a data cleaning instruction to the set application program based on the cache data amount under each data storage path in the sandbox, wherein the data cleaning instruction comprises the identification of the target application program and the data storage path to be cleaned. The setting application program determines a target application program based on the identification of the target application program, and sends a data cleaning instruction to the target application program, so that the target application program cleans the cache data under the data storage path to be cleaned.
Here, it should be noted that, since the server may communicate with the setting application through the first data protocol, and the setting application may communicate with the target application through the second data protocol, the first data protocol communication is different from the second data protocol communication, and in this case, if the data cleaning instruction is directly sent to the target application, there may be a case that the target application cannot recognize the data cleaning instruction. In view of this, in the present application, after the application program is set to receive the data cleaning instruction sent by the server, format conversion packaging is performed on the data in the data cleaning instruction, and after the target application program receives the data cleaning instruction, data analysis is performed on the data cleaning instruction after format conversion packaging, so as to obtain the cache data under the data storage path to be cleaned.
In addition, because sandboxes corresponding to the apps are isolated from each other under the IOS system, the sandboxes allocated to the current App by the system cannot be accessed by the outside. In the implementation, the setting application program is matched with the SDK for use, and in particular, because some mechanisms in the SDK can interact with the setting application program, the setting application program can control and clear the sandboxed file of the target application program, namely, the setting application program sends a data clearing instruction to the SDK, and the SDK directly executes data clearing after receiving the data clearing instruction.
According to the sandbox-based data cleaning method, the data cleaning instruction sent by the setting application program to the setting application program based on the cache data quantity under each data storage path in the sandbox corresponding to the target application program is received by the server, and the cleaning of the cache data under the data storage path to be cleaned can be completed based on the data cleaning instruction.
In the embodiment of the application, the data cleaning method based on the sandboxes further comprises the following steps: detecting the cache data quantity under each data storage path in the sandbox corresponding to the target application program in real time through the SDK; and sending the cached data quantity under each data storage path in the sandbox to the setting application program, so that the setting application program sends the cached data quantity under each data storage path in the sandbox and the identification of the target application program to the server.
In practical application, the target application program can acquire the cache data volume under each data storage path in the sandbox at regular time or in real time, and send the cache data volume to the setting application program, and then send the cache data volume to the server through the setting application program for reference by a developer or the server, so that the server can issue more accurate data cleaning instructions.
Specifically, as an implementation manner, after the server receives the amount of cache data under each data storage path in the sandbox sent by the target application program, the amount of cache data under each data storage path may be compared with a preset threshold, and if the amount of cache data under a certain data storage path is greater than the preset threshold, the server directly issues a data cleaning instruction to the set application program, so as to clean the cache data under the data storage path.
As another implementation manner, after the server receives the amount of the buffered data under each data storage path in the sandbox sent by the target application program, the developer may compare the amount of the buffered data under each data storage path with an empirical value or a preset threshold value, and if the amount of the buffered data under a certain data storage path is greater than the empirical value or the preset threshold value, the developer controls the server to issue a data cleaning instruction to the set application program, so as to clean the buffered data under the data storage path.
Fig. 3 is a schematic diagram of another sandbox-based data cleaning method according to an embodiment of the present application, where the method is applied to a server, and as shown in fig. 3, the method includes:
Step 301, establishing communication connection with a setting application program in a user terminal, wherein the user terminal comprises the setting application program and a target application program running by adopting a sandbox mechanism, and the target application program is in communication connection with the setting application program.
Step 302, obtaining the cache data volume under each data storage path in the sandbox corresponding to the target application program in real time.
Step 303, according to the amount of the cache data in each data storage path in the sandbox corresponding to the target application program, sending a data cleaning instruction to the set application program, where the data cleaning instruction includes the identifier of the target application program and the data storage path to be cleaned, so that the set application program sends the data cleaning instruction to the target application program, and the target application program cleans the cache data in the data storage path to be cleaned.
When the method is implemented, the server firstly establishes communication connection with the set application programs in the user terminal, acquires the cache data amount under each data storage path in the sandbox corresponding to the target application program in real time, and then sends a data cleaning instruction to the set application program based on the cache data amount under each data storage path in the sandbox, wherein the data cleaning instruction comprises the identification of the target application program and the data storage path to be cleaned. The setting application program determines a target application program based on the identification of the target application program, and sends a data cleaning instruction to the target application program, so that the target application program cleans the cache data under the data storage path to be cleaned.
Here, it should be noted that, since the server may communicate with the setting application through the first data protocol, and the setting application may communicate with the target application through the second data protocol, the first data protocol communication is different from the second data protocol communication, and in this case, if the data cleaning instruction is directly sent to the target application, there may be a case that the target application cannot recognize the data cleaning instruction. In view of this, in the present application, after the application program is set to receive the data cleaning instruction sent by the server, format conversion packaging is performed on the data in the data cleaning instruction, and after the target application program receives the data cleaning instruction, data analysis is performed on the data cleaning instruction after format conversion packaging, so as to obtain the cache data under the data storage path to be cleaned.
According to the sandbox-based data cleaning method provided by the embodiment of the application, the communication connection between the set application programs in the user terminal is established, the cache data amount under each data storage path in the sandbox corresponding to the target application program is obtained in real time, and then the data cleaning instruction is sent to the set application program according to the cache data amount under each data storage path in the sandbox corresponding to the target application program, so that the set application program sends the data cleaning instruction to the target application program, and cleaning of cache data under the data storage path to be cleaned by the target application program can be completed based on the data cleaning instruction. The method and the system have the advantages that a user does not need to manually initiate a data cleaning instruction, the server can automatically clean the cache data according to the cache data quantity under each data storage path in the sandbox corresponding to the target application program, and the cleaning efficiency and accuracy are high.
In the embodiment of the application, the method for acquiring the cache data volume under each data storage path in the sandbox corresponding to the target application program in real time comprises the following steps: and receiving the buffer data quantity under each data storage path in the sandbox corresponding to the target application program forwarded by the setting application program in real time, wherein the buffer data quantity under each data storage path in the sandbox is detected by the software development kit SDK integrated in the target application program in real time, and the setting application program and the target application program are in data communication through the SDK.
In practical application, because sandboxes corresponding to apps under the IOS system are isolated from each other, the sandboxes allocated to the current App by the system cannot be accessed by the outside. In the implementation, the setting application program is matched with the SDK for use, and in particular, because some mechanisms in the SDK can interact with the setting application program, the setting application program can control and clear the sandboxed file of the target application program, namely, the setting application program sends a data clearing instruction to the SDK, and the SDK directly executes data clearing after receiving the data clearing instruction.
In the implementation, the target application program can acquire the cached data quantity under each data storage path in the sandbox at regular time or in real time, and send the cached data quantity to the setting application program, and then send the cached data quantity to the server through the setting application program, so that the server receives the cached data quantity under each data storage path in the sandbox corresponding to the target application program forwarded by the setting application program in real time.
After the server receives the cache data volume under each data storage path in the sandbox corresponding to the target application program, a data cleaning instruction can be issued according to the cache data volume.
Specifically, as an implementation manner, after the server receives the amount of cache data under each data storage path in the sandbox sent by the target application program, the amount of cache data under each data storage path may be compared with a preset threshold, and if the amount of cache data under a certain data storage path is greater than the preset threshold, the server directly issues a data cleaning instruction to the set application program, so as to clean the cache data under the data storage path.
As another implementation manner, after the server receives the amount of the buffered data under each data storage path in the sandbox sent by the target application program, the developer may compare the amount of the buffered data under each data storage path with an empirical value or a preset threshold value, and if the amount of the buffered data under a certain data storage path is greater than the empirical value or the preset threshold value, the developer controls the server to issue a data cleaning instruction to the set application program, so as to clean the buffered data under the data storage path.
It should be noted that, the setting application program in the present application may uniformly receive and send commands to a plurality of application programs to implement a multi-application group control scenario. Specifically, for example, the setting application program receives the amount of cache data under each data storage path sent by the plurality of target application programs, and the server may issue different data cleaning instructions to different target application programs through the setting application program according to the amount of cache data under each data storage path of each target application program, where the data cleaning instructions include the identification of the target application program, so that the data cleaning instructions can be accurately sent to each target application program.

The control server 401 establishes communication connection with the setting application program 4021 in the user terminal 402, acquires the cache data amount under each data storage path in the sandbox corresponding to the target application program 4022 in real time, sends a data cleaning instruction to the setting application program 4021 according to the cache data amount under each data storage path in the sandbox corresponding to the target application program 4022, and after the setting application program 4021 receives the data cleaning instruction sent by the server 401, sends the data cleaning instruction to the target application program 4022, and after the target application program 4022 receives the data cleaning instruction sent by the setting application program 4021, the cache data under the data storage path to be cleaned can be cleaned.
