Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, the following detailed description of the embodiments of the present application will be made with reference to the accompanying drawings.
The terms "first," "second," "third," and "fourth," etc. in the description and claims of this application and in the accompanying drawings, if any, are used for distinguishing between different objects and not for describing a particular order. Furthermore, the terms "comprising" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those steps or elements listed, but may alternatively include other steps or elements not listed, or inherent to such process, method, article, or apparatus.
Fig. 1 is a schematic diagram of an implementation environment provided by an embodiment of the present application. Referring to fig. 1, the implementation environment includes a terminal 101 and a server 102; the terminal 101 and the server 102 are connected through a wireless or wired network. In addition, an application program that the server 102 provides services may be installed on the terminal 101, and a user corresponding to the terminal 101 may implement functions such as data transmission and message interaction through the application program.
The terminal 101 may be a computer, a mobile phone, a tablet computer or other electronic devices. The application program may be any application program installed on the terminal 101; the application program may be an application program in the operating system of the terminal 101, or may be an application program provided by a third party. For example, the application may be a social application, a music application, a video application, a shopping application, or an information browsing application, among others. The information browsing application may be a news application or a reading application, etc. The server 102 may be a backend server 102 for an application. Accordingly, the server 102 may be a social application server, music server, video server, shopping server, or information browsing application server, among others.
In the android system, access to data is primarily through Content Provider (Content Provider) components. Referring to fig. 2, the application may Access different Data through a content provider component, and specifically, the application of the Business Layer (Business Layer) may perform read and write operations on a network resource (Internet), a lightweight database (SQLite), and a file (Files) of the Data Layer (Data Layer) through the content provider component of the Data Access Layer (Data Layer) based on an inter-process communication mechanism (Binder) and an Anonymous Shared Memory subsystem (Ashmem).
In the embodiment of the application, two identical application programs can be simultaneously run on the terminal. Where one application runs inside the sandbox and another application runs outside the sandbox. To distinguish between the two applications, the application running inside the sandbox is described as the first application and the application running outside the sandbox is described as the second application. The first application and the second application may run based on different accounts, for example, the applications are social applications, the first application may log in to a work account for work communication, and the second application may log in to a personal account for personal life communication. The application program may store some data with a large occupied space in the external storage space, for example, some data such as pictures, videos, audios, or files with a large occupied space may be stored in the external storage space. A first application program in the sandbox may perform a read/write operation on data through a virtual storage space in the sandbox, where the virtual storage space is implemented by redirecting a data path, and referring to fig. 3, the first application program initiates a read/write operation on the data, hooks the read/write operation on the data by hooking the first application program through a Hook (Hook) technology, redirects the data path specified by the read/write operation to the virtual storage space in the sandbox, and implements the read/write operation on the data in the virtual storage space in the sandbox through system call. For example, the data path designated by the first application program for reading and writing data is "/sdcard/content/QQ _ Images", and the data path is redirected to "/sdcard/sandbox/content/QQ _ Images" to implement the reading and writing operation of the first application program for data of the virtual storage space in the sandbox.
And the data path of the first application program is redirected, and only the data in the virtual storage space can be accessed, so that the data stored by the first application program and the data stored by the second application program are isolated. In practical applications, some data stored by the first application and the second application do not need to be isolated, for example, some pictures that can be disclosed do not need to be isolated. By the method provided by the embodiment of the application, the terminal can flexibly access the data according to the dynamically set authority information of the data. For example, referring to fig. 4, when a first application wants to access a multimedia library, a check of the rights information needs to be made. When the permission information is used for indicating that the first application program has the permission to access the multimedia library of the second application program, namely the permission information is allowed to access, the first application program can access the multimedia library of the second application program; when the permission information is used to indicate that the first application does not have permission to access the multimedia library of the second application, the first application does not access the multimedia library of the second application.
When the first application program accesses data, the terminal redirects a path for accessing the data. The terminal can redirect the path according to the redirection rule. The redirection rule may be to add a sandbox prefix or delete a sandbox prefix. The sandbox prefix in the path may be "/sandbox". For example, referring to fig. 5, when the path of the first application accessing data is "/sdcard/app1/Images (/ memory card/first application/picture)", the terminal redirects the path of the first application accessing data to "/sdcard/sandbox/app1/Images (/ memory card/sandbox/first application/picture)". When the path of the data accessed by the first application program is '/sdcard/sandbox/app 1/Images', the terminal redirects the path of the data accessed by the first application program to '/sdcard/app 1/Images'.
Fig. 6 is a flowchart of a data access method according to an embodiment of the present application. Referring to fig. 6, the embodiment includes:
601. the terminal receives a data access request sent by a first application program on the terminal, wherein the data access request carries a first access path for accessing data to be accessed.
The data access request is used for requesting to access the data to be accessed. The first access path is a path for storing the data to be accessed in the storage space, and is used for reading the data to be accessed from the storage space.
When an interface of a first application program is displayed on the terminal and an access operation which is executed by a user and used for indicating data to be accessed is received, the first application program sends a data access request to an operating system of the terminal. The operating system receives a data access request sent by a first application program on the terminal, wherein the data access request carries a first access path for accessing data to be accessed. The access operation performed by the user to indicate the data to be accessed may be a click operation, a gesture operation, a voice control operation, or the like, which is not specifically limited herein.
For example, the first application program is a social application, when a chat interface of the first application program is displayed on the terminal, the user clicks a control sharing a picture of the second application program on the interface, the first application program sends a data access request to the operating system, the data access request is used for requesting to access the picture of the second application program, and the data access request carries a first access path of the picture of the second application program.
602. The terminal acquires a path index of the first access path.
The path index of the first access path is used to determine whether the first access path is used to access a memory space corresponding to a first application within the sandbox or is used to determine whether the first access path is used to access a memory space corresponding to a second application outside the sandbox.
The terminal may obtain the path index of the first access path from a database storing the first access path and the path index of the first access path.
Before acquiring the path index of the first access path, the terminal may generate the path index of the first access path, and store the first access path and the index of the first access path in the database. In a possible implementation manner, the step of generating, by the terminal, the path index of the first access path may be: when the terminal stores the data to be accessed, the path index of the first access path is determined according to the number of the data stored in the storage space corresponding to the application program for storing the data to be accessed.
For example, when the application on the terminal stores the data to be accessed, if the number of the data already stored in the storage space of the application is 10, the data to be accessed is the 11 th data to be stored by the application, and the path index of the first access path for generating the data to be accessed is 11.
In another possible implementation manner, the terminal may generate an index of the first access path according to a form of the first access path. Correspondingly, the step of generating, by the terminal, the path index of the first access path may further be: when the terminal stores the data to be accessed, generating a first access path of the data to be accessed according to information such as an application program where the data to be accessed is located, the data type of the data to be accessed and the like; and the terminal generates a path index of the data to be accessed according to the form of the first access path of the data to be accessed.
For example, a path for accessing memory corresponding to a first application within a sandbox typically carries a "sandbox" and a path for accessing memory corresponding to a second application outside of the sandbox typically does not carry a "sandbox". The terminal may generate an index of the first access path according to whether the first access path has "sandbox". When the first access path does not contain the 'sandbox', generating an index of the first access path as '0'; when the first access path has "sandbox", the index of the first access path is generated to be "1".
603. And the terminal determines that the data access request is used for accessing the data of the second application program on the terminal according to the path index.
When the first application program accesses data through the content provider component, the path access tool can be obtained through the content provider component, and the data access request is determined to be used for accessing data of a second application program on the terminal according to the matching condition of the path index and the index in the path access tool. Correspondingly, the steps can be as follows: the terminal matches the path index with each index in the path access tools, wherein the path access tools comprise a first path access tool and a second path access tool, the first path access tool comprises a first index of a first storage path of at least one first data of a first application program, and the second path access tool comprises a second index of a second storage path of at least one second data of a second application program; when the path index matches a second index in the second path access tool, it is determined that the data access request is for accessing data of a second application on the terminal. When the path index matches a first index in the first path access tool, it is determined that the data access request is for accessing data of a first application on the terminal.
For example, the indices in the path access tool are "1", "2", "3", "4", and "5"; the first index in the first path access tool is "1", "2", and "4"; the second index in the second path access tool is "3" and "5". When the path index of the first access data is '3', the path index is matched with a second index in a second path access tool, and the data access request is determined to be used for accessing data of a second application program on the terminal; when the path index of the first access data is "2", the path index is matched with the first index in the first path access tool, and it is determined that the data access request is for accessing data of the first application program on the terminal.
Referring to fig. 7, when the first application accesses data through the content provider component, the path access tool may be obtained through a query method provided by the content provider component. The terminal acquires the path index of the first access path, and matches the path index with the index in the path access tool, so that the data access request can be determined to be used for accessing the data of the first application program on the terminal or the data access request is used for accessing the data of the second application program on the terminal. In a sandbox scenario, redirection of the path is generally achieved by adding a "sandbox" to the path. The first storage path of the data of the first application is usually provided with a "sandbox", and the first storage path of the first application can be regarded as a "redirected" path, the second storage path of the data of the second application is usually not provided with a "sandbox", and the second storage path of the data of the second application can be regarded as a path without "redirected". The determination that the data access request is for accessing data of the first application on the terminal or the data access request is for accessing data of the second application may be regarded as a determination of whether the first access path is redirected. When the first access path is redirected, the data access request is indicated for accessing data of the first application program, and when the first access path is not redirected, the data access request is indicated for accessing data of the second application program.
It should be noted that, before matching the path index with each index in the path access tool, the path access tool needs to be generated according to a first storage path of data stored in the first application program and a second storage path of data stored in the second application program. Correspondingly, generating the path access tool according to the first storage path of the data stored by the first application program and the second storage path of the data stored by the second application program can be realized through the following steps (1) to (3):
(1) The terminal acquires a first storage path of at least one first data of a first application program and a second storage path of at least one second data of a second application program.
When the terminal applies the data access method provided by the embodiment of the application for the first time, a path access tool needs to be initialized. The terminal needs to acquire a first storage path of at least one first data stored in a storage space of a current first application program in the sandbox and a second storage path of at least one second data stored in a storage space of a current second application program outside the sandbox.
For example, when the terminal initializes the path access tool, the first application program stores 10 first data in the storage space inside the sandbox, the second application program stores 8 second data in the storage space outside the sandbox, and the terminal needs to obtain a first storage path of each first data in the 10 first data and a second storage path of each second data in the 8 second data, respectively.
When new first data is stored in a storage space corresponding to a first application program or new second data is stored in a storage space corresponding to a second application program, the terminal acquires a first storage path of the first data or a second storage path of the second data.
(2) And the terminal generates a first index corresponding to the first storage path of each first data according to the first storage path of each first data, and generates a second index corresponding to the second storage path of each second data according to the second storage path of each second data.
This step is similar to the step of generating the path index of the first access path by the terminal, and is not described herein again.
(3) The terminal encapsulates a first index corresponding to a first storage path of each first data in a first path access tool, and encapsulates a second index corresponding to a second storage path of each second data in a second path access tool; merging the first path access tool and the second path access tool into a path access tool.
The terminal encapsulates a first index corresponding to the first storage path of each first data in the first path access tool, and when the path index of the first access path matches the first index in the first path access tool, it may be determined that the data access request corresponding to the first access path is used for accessing the data of the first application. And the terminal encapsulates a second index corresponding to a second storage path of the second data in the second path access tool, and when the path index of the first access path is matched with the second index in the second path access tool, the terminal can determine that the data access request corresponding to the first access path is used for accessing the data of the second application program.
The terminal merges a first path access tool and a second path access tool into the path access tool, when a first application program accesses data through a content provider component, the path access tool can be obtained through a query method provided by the content provider component, a path index of a first access path is matched with a first index in the first path access tool and a second index in the second path access tool respectively, when the path index of the first access path is matched with the first index in the first path access tool, a data access request is determined to be used for accessing data of the first application program, and when the path index of the first access path is matched with the second index in the second path access tool, the data access request is determined to be used for accessing data of the second application program.
Another point to be noted is that the terminal can determine that the data access request is for accessing data of the second application on the terminal through steps 602 and 603. The terminal may also determine, based on the form of the first access path, that the data access request is for accessing data of a second application on the terminal. In a sandbox scenario, a first storage path for data of a first application is typically provided with a "sandbox" and a second storage path for data of a second application is typically not provided with a "sandbox". The data access request may be determined for accessing data of the first application on the terminal or the data access request for accessing data of the second application by determining whether the first access path has "sandbox" therein. And when the first access path has the 'sandbox', determining that the data access request is used for accessing the data of the first application program on the terminal, and when the first access path does not have the 'sandbox', determining that the data access request is used for accessing the data of the second application program on the terminal.
It should be noted that, according to the path index, the terminal may also determine that the data access request is used for accessing the data of the first application program on the terminal. When the terminal determines that the data access request is for accessing the data of the first application on the terminal according to the path index, step 604 and step 605 are not performed any more.
When the terminal determines that the data access request is used for accessing the data of the first application program on the terminal according to the path index, converting the first access path into a second access path; redirecting the second access path to a third access path; and based on the third access path, reading data corresponding to the third access path from the storage space corresponding to the third access path, and returning the read data corresponding to the third access path to the first application program. With continued reference to fig. 7, when the terminal determines that the data access request is for accessing data of the first application on the terminal, i.e., that the first access path is redirected, the first access path is converted into the second access path.
Wherein the step of converting the first access path into the second access path may be implemented according to a redirection rule. For example, the first access path is "/sdcard/sandbox/concentration/QQ _ Images", and the second access path converted according to the redirection rule is "/sdcard/concentration/QQ _ Images".
When the first application program accesses data, the terminal redirects a path for accessing the data. The terminal may redirect the second access path to a third access path. For example, the second access path is "/sdcard/tencent/QQ _ Images", and the redirected third access path is "/sdcard/sandbox/tencent/QQ _ Images". The third access path is the same as the first access path and is used for accessing data of the first application program.
In this embodiment, the terminal may match the path index of the first access path with an index in the path access tool, and determine that the data access request is for accessing data of a second application program on the terminal or that the data access request is for accessing data of a first application program on the terminal. The data access request is determined to be used for accessing the data of which application program in a matching index mode, and the efficiency is high.
604. And when the data access request is determined to be used for accessing the data of the second application program on the terminal according to the path index, the terminal acquires the authority information of the data to be accessed.
The first application program and the second application program are the same application program, the first application program runs in a sandbox of the terminal, and the second application program runs outside the sandbox.
The terminal may store the authority information of the data to be accessed in a storage space accessible by the first application, and when it is determined that the data access request is for accessing data of the second application on the terminal, the terminal acquires the authority information of the data to be accessed from the storage space in which the authority information is stored. The terminal can associate the first access path of the data to be accessed with the authority information of the data to be accessed, and acquire the authority information of the data to be accessed according to the first access path. The terminal can also associate the path index of the first access path of the data to be accessed with the authority information of the data to be accessed, and acquire the authority information of the data to be accessed according to the path index.
The terminal can also store the authority information of the data to be accessed in the server, and when the data access request is determined to be used for accessing the data of the second application program on the terminal, the terminal acquires the authority information of the data to be accessed from the server.
The terminal may also obtain the permission information of the data to be accessed through other manners, and the manner in which the terminal obtains the permission information of the data to be accessed is not particularly limited herein.
In the embodiment of the application, the terminal can acquire the authority information of the data to be accessed, so that the data can be accessed according to the authority information, and the flexibility of data access is improved.
It should be noted that the terminal supports the user to set the authority information of the data when storing the data. In a possible implementation manner, before the terminal acquires the permission information of the data to be accessed, the permission information set by the second application program may be received. Correspondingly, the step that the terminal supports the user to set the authority information of the data when the data is stored can be as follows: in the second application program, when a storage instruction of data to be accessed is received, the terminal displays a setting interface of the authority information; when receiving an operation of allowing a first application program to access data to be accessed based on a setting interface, setting authority information of the data to be accessed as permission to access by the terminal; when receiving an operation of prohibiting the first application program from accessing the data to be accessed based on the setting interface, the terminal sets the authority information of the data to be accessed as prohibited access.
When the terminal runs the second application program and the user triggers the operation of storing the data to be accessed, the terminal receives a storage instruction of the data to be accessed and displays a setting interface of the permission information. The setup interface is used to ask the user whether the first application in the sandbox has access to the data to be accessed. For example, the setting interface may be configured as a pop-up window, and when the user triggers the operation of saving the picture, the setting interface is displayed in the current interface, and provides text information of whether the picture allows the first application program to access and clickable yes and no buttons. When the clicking operation of 'yes' is received, the terminal sets the authority information of the picture as access permission, and when the clicking operation of 'no' is received, the terminal sets the authority information of the picture as access prohibition.
In another possible implementation manner, the terminal further supports that the user sets the authority information for the stored data. Before the terminal acquires the authority information of the data to be accessed, the authority information set by the user can be received through a setting interface in an operating system of the terminal or a setting interface of an application program of a sandbox environment provided on the terminal. Correspondingly, the step that the terminal supports the user to set the authority information for the stored data may be: the terminal displays an authority setting interface corresponding to the second application program; when receiving an operation of allowing the first application program to access the data of the second application program based on the permission setting interface, the terminal sets permission information of the data of the second application program to allow access; when receiving an operation of prohibiting the first application program from accessing the data of the second application program based on the authority setting interface, the terminal sets the authority information of the data of the second application program as prohibited to access.
The terminal can set the permission setting interface corresponding to the second application program as a sub-interface of the setting interface in the terminal operating system. The terminal can also set the permission setting interface corresponding to the second application program as a sub-interface of the setting interface of the application program providing the sandbox environment on the terminal. The terminal can also set the authority setting interface corresponding to the second application program as a sub-interface of the second application program.
And when receiving the operation that the user sets that the second application program can be opened in a double mode or receiving the operation that the user opens the authority setting interface, displaying the authority setting interface for inquiring whether the first application program of the user can access the data of the second application program. For example, a permission setting interface is displayed in the current interface, and the permission setting interface can provide text information of whether the first application can access all data of the second application and clicked yes and no buttons. When the clicking operation of 'yes' is received, the terminal sets the authority information of the data of the second application program to be allowed to access, namely the first application program can access all the data stored in the external storage space by the second application program; when the clicking operation of 'no' is received, the terminal sets the authority information of the data of the second application program to be access-prohibited, namely the first application program does not have the authority of accessing the data of the second application program.
The permission setting interface may also be used to ask the user which data of the second application the first application is able to access. For example, a pop-up window is displayed in the current interface, and the pop-up window can provide text information of which data of the second application can be accessed by the first application, and options of "picture", "video and audio", "document", and "access prohibition", etc. When receiving an operation that a user selects a picture option, the terminal sets the permission information as a picture which can be stored in an external storage space by a first application program and can be accessed by a second application program; when receiving an operation that a user selects an 'access prohibition' option, the terminal sets the authority information as the authority of the first application program which does not access the data of the second application program.
In the embodiment of the application, the terminal supports the user to set the authority information of the data to be accessed, the user can set which data can be shared and which data cannot be shared according to the self requirement, and the experience degree of the user can be improved.
605. When the first application program is determined to have the authority to access the data to be accessed according to the authority information, the terminal shields the redirection of the first access path; and based on the first access path, reading the data to be accessed from the storage space corresponding to the first access path, and returning the read data to the first application program.
When the first application program accesses the data, the terminal redirects the path of the accessed data. When the first application program is determined to have the right to access the data to be accessed, the first application program is allowed to access the data to be accessed of the second application program, and the first access path pointing to the storage space of the second application program does not need to be redirected. When the first application has the right to access the data to be accessed of the second application, the terminal needs to shield the redirection to the first access path.
When the terminal determines that the first application has the right to access the data to be accessed, it may be marked that the first access path does not need to be redirected. For example, when the terminal determines that the first application has the right to access the data to be accessed, the first access path may carry a flag "1", the flag "1" being used to indicate that the first access path does not need to be redirected. Before the terminal executes the redirection operation to the first access path, whether the first access path carries a mark '1' is judged. If the first access path carries the mark '1', the redirection operation of the first access path is not executed, namely the redirection of the first access path is shielded; and if the first access path does not carry the label '1', executing redirection operation on the first access path.
In the embodiment of the application, when the first application program has the right to access the data of the second application program, the terminal shields the redirection of the first access path, so that the first application program can access the data of the second application program, the data of the first application program and the data of the second application program are not completely isolated any more, and the flexibility of data access is improved.
It should be noted that, according to the permission information, the terminal may also determine that the first application does not have the permission to access the data to be accessed. When the first application program does not have the right to access the data to be accessed, the first application program cannot access the data to be accessed.
In a possible implementation manner, when the terminal determines that the first application does not have the right to access the data to be accessed, the first access path is redirected to the storage space corresponding to the first application, and the data is read from the storage space corresponding to the first application. Correspondingly, when the terminal determines that the first application program does not have the right to access the data to be accessed, the step of accessing the data may be: when the terminal determines that the first application program does not have the authority to access the data to be accessed according to the authority information, converting the first access path into a second access path; and based on the second access path, reading the data corresponding to the second access path from the storage space corresponding to the second access path, and returning the read data corresponding to the second access path to the first application program.
In one possible implementation, the second access path may be a path generated by the first access path according to a redirection rule. The redirection rule may add a "sandbox" prefix at a specified location of the first access path. For example, the first access path is "/sdcard/tencent/QQ _ Images/img _1", and the second access path generated by the first access path according to the redirection rule may be "/sdcard/sandbox/tencent/QQ _ Images/img _1".
In another possible implementation manner, the second access path has no corresponding data in the storage space corresponding to the second access path. And when the data corresponding to the second access path cannot be read from the storage space corresponding to the second access path, returning prompt information, wherein the prompt information is used for indicating that the first application program does not have the right of accessing the data to be accessed.
In another possible implementation manner, when the terminal determines that the first application does not have the right to access the data to be accessed, the terminal may also directly return a prompt message, where the prompt message is used to indicate that the first application does not have the right to access the data to be accessed. The step of converting the first access path to the second access path is not performed anymore.
In another possible implementation manner, when the terminal determines that the first application does not have the right to access the data to be accessed, the terminal may not return any information or data and may not perform the step of converting the first access path into the second access path.
It should be noted that, with reference to fig. 7, when it is determined that the first application has the right to access the data to be accessed, that is, when it is determined that the first access path is not redirected, the terminal shields redirection of the first access path. Based on the first access path, reading data to be accessed from a storage space corresponding to the first access path, returning the read data to the first application program, namely after completing data operation, removing the shielding of the redirection of the first access path, namely recovering the redirection of the first access path.
In the embodiment of the application, when the first application program does not have the authority to access the data of the second application program, the first application program does not access the data to be accessed of the second application program, and the security of data access can be improved.
In the embodiment of the application, the path index and the authority information are introduced, when the first application program in the sandbox is determined to access the data of the second application program outside the sandbox and has the authority of accessing the data of the second application program according to the path index and the authority information, the redirection of the first access path is shielded, and the data to be accessed is accessed based on the first access path. When the first application program has the authority of accessing the data of the second application program, the first application program can access the data of the second application program, and the flexibility of data access is improved.
