According to an embodiment of the present application, there is provided an operation control method of an application program.
Fig. 1 is a flowchart of an operation control method of an application according to an embodiment of the present application. As shown in fig. 1, the method comprises the steps of:
Step S102, in the process of starting the application program of the computer, intercepting the access operation of the application program to the application program instance, wherein the application program instance is used for representing the starting state of the application program.
Specifically, when the application program is started, an application program instance corresponding to the application program is stored at a preset address, the application program accesses the preset address, when the corresponding application program instance is accessed, the application program is indicated to be started, when the corresponding application program instance is not accessed, the application program is indicated to be not started, and the current starting is the first starting.
Optionally, in the method for controlling operation of an application program provided by the embodiment of the present application, an operating system of a computer is a LINUX system.
Specifically, under the LINUX system, the starting of the application program is controlled through a single-instance implementation mechanism of the application program, that is, when the corresponding application program instance is accessed in the process of the current starting, the starting of the application program is prevented, and when the corresponding application program instance is not accessed, the starting of the application program is allowed.
Optionally, in the method for controlling operation of an application program provided by the embodiment of the present application, an address where an application program instance is located is one of the following: the target file address under the installation path of the application program, and the memory address of the target server of the application program is monitored.
Specifically, under the LINUX system, on the one hand, after the application program is started, the application program instance may be stored in a specific form under a specific path, for example, in a file form under an installation path of the application program, that is, an address where the application program instance is located may be a target file address under the installation path of the application program.
On the other hand, the platform of the LINUX system controls all application programs through a dbus protocol (in a message bus manner), the application programs are supervised by Dbus services, and after the application programs are started, application program instances can exist in a memory of the dbus service of the system, namely, an address where the application program instances are located can be a memory address of the dbus service.
Thus, in the LINUX system, the single instance implementation mechanism of the application program may be implemented by detecting whether a certain file exists in a special path, and in some application programs using Dbus buses, it may also be implemented by detecting whether a specific service name of a service connected by Dbus buses exists.
In the method for controlling the operation of the application program provided by the embodiment of the application, before the access operation of the application program to the application program instance is intercepted in the process of starting the application program of the computer, the method further comprises the following steps: starting an operating system of the computer and starting a process corresponding to the application program; and injecting a hook function into the memory space of the started process, wherein the hook function is used for monitoring an interface function called by the application program when the process runs and controlling the execution behavior of the interface function.
Specifically, after the operating system of the computer is started, and after the user starts the application program, the hook function is injected into the internal space of the started process, so as to monitor and control the interface function called in the process.
For example, in the LINUX system, the loading of the interception module can be completed by using a ld_ preload mechanism under the operating system, i.e. the path of the library file where the processing function of the interface function to be intercepted is located is written into the/etc/so.preload file.
Optionally, in the method for controlling operation of an application program provided by the embodiment of the present application, intercepting an access operation of the application program to an application program instance in a process of starting the application program of a computer includes: and intercepting a first dynamic link library called by the application program through the hook function, wherein the first dynamic link library comprises a first access function, and the first access function is used for accessing the application program instance.
Specifically, in the case that the operating system of the computer is a LINUX system, the interface function corresponding to the access operation is stored in a libc.so library or a libdbus.so library, and an open function in the libc.so library or a dbus_bus_request_name function in the libdbus.so library is intercepted by using an inline hook technology to intercept the access operation of the application program to the application program instance.
Specifically, for an application program which determines whether an instance is running by detecting whether a file exists, the access of the application program to the file under a specific path is intercepted, for the application program which determines whether the instance is running by detecting Dbus service names exists, the access of the application program to the memory of Dbus service is intercepted, so that whether the application program instance is running is checked, if the application program instance is not running, the interception is released, otherwise, the access address of the access operation is redirected, the limitation of the application program single instance is released, the application program can be started again, and the separation of the application program or the application of multiple applications are realized.
Step S104, the access address of the access operation is redirected to the target address, and a target access result returned based on the target address is received, wherein the target access result is used for indicating that no application program instance exists.
Specifically, the file accessed by the application program or Dbus service names are redirected, so that the application program accesses the target address, and an access result without the application program instance is received, thereby bypassing the detection mechanism of the single instance of the application program and realizing the separation or multiple separation of the application program.
In order to avoid unnecessary redirection operations, optionally, in the method for controlling operation of an application program provided in the embodiment of the present application, after intercepting an access operation of an application program to an application program instance in a process of starting the application program of a computer, the method further includes: judging whether an application program instance exists in an access address of the access operation; in the presence of an application instance, the step of redirecting the access address of the access operation to the target address is performed.
That is, when an application program instance exists in the access address of the access operation, the access address redirection operation for the access operation is executed again, and when an application program instance does not exist in the access address of the access operation, the access address redirection operation for the access operation is not executed.
Optionally, in the method for controlling operation of an application program provided by the embodiment of the present application, redirecting an access address of an access operation to a target address and receiving a target access result returned based on the target address includes: the control application program obtains target function parameters of a second access function in the second dynamic link library, wherein the target function parameters comprise access addresses, and the access addresses of the second access function are different from those of the first access function; and receiving an access result of the non-existing application program instance returned by the first access function based on the target function parameter execution access behavior.
It should be noted that when an application program runs, multiple modules are required to be called through an API interface of the application program to load the corresponding functions of the program, the first dynamic link library and the second dynamic link library are corresponding sets formed by 1 module or N modules, each function is running in a certain module, and one module includes multiple API functions, such as an access function, and replacement of the access result can be achieved by adjusting the calling process of the API functions in the dynamic link library.
In an alternative embodiment, the first access function is an Open function, the Open function is in the first link library libc.so library, to change the access address of the Open function, the Open function in the first link library libc.so library is intercepted, for example, the address in the memory space where the Open function in the first link library libc.so is located is set, and when the Open function is called by the application program, the Open function is redirected to the memory space where the second access function corresponding to the libc.so library is located, that is, the call is performed by jumping to the memory space where the second access function is located, so as to achieve the purpose of adjusting the call process of the access function. For example, the original file under the c disc is called instead of the file in the d disc, and the returned access result of the application program instance does not exist because the file in the d disc does not exist, so that the replacement of the returned value of the access function is realized.
And step S106, controlling the application program to finish starting based on the target access result.
Specifically, an access result of the second access function executing access behavior, which is returned by the second access function executing access behavior and is free of the application program instance, is received, and the current starting of the application program is allowed.
According to the running control method of the application program, the access operation of the application program to the application program instance is intercepted in the process of starting the application program of the computer, wherein the application program instance is used for representing the starting state of the application program; redirecting an access address of the access operation to a target address and receiving a target access result returned based on the target address, wherein the target access result is used for indicating that no application program instance exists; the method and the device control the application program to finish starting based on the target access result, and solve the problem that a plurality of same application programs cannot be started and run simultaneously under a LINUX system in the related technology. By intercepting the access operation of the application program to the application program instance and redirecting the access address of the access operation, the effect that a plurality of identical application programs can be started and simultaneously run under the LINUX system is achieved.
Fig. 2 is a schematic diagram of another method of controlling the operation of an application according to an embodiment of the present application. As shown in fig. 2, the method includes:
And after the LINUX system is started, the hook installation module is operated to complete the hook module installation.
When a user starts chat application or office software and a process is started, an interception processing module is loaded to intercept open and dbus_bus_request_name functions.
The state of the program running in the system is checked to see if an instance of the user initiated program already exists.
If the file or Dbus is accessed, the interception module calls a redirection module to redirect the access of the file or Dbus to realize the restarting of the application when the program is started; if not, the interception module releases the file or Dbus access request, and the program started by the user is loaded and operated.
During the running process of the program, whether the system is exited is checked, and if so, the system is exited.
According to the embodiment, an open function in a libc.so library and a dbus_bus_request_name function in the libdbus.so library are intercepted by using an inline hook technology, a single-instance detection mechanism of an application program is broken, the application program is split or the application is more open, and special requirements of users are met.
Fig. 3 is a schematic diagram of an alternative application program operation control method according to an embodiment of the present application. As shown in fig. 3, the method includes:
After entering the LINUX operating system, logging in the account system, and verifying the post-synchronization ciphertext control strategy.
Under the condition that a user double clicks to open the file, checking whether the opened file is ciphertext, if so, starting a new process to open the ciphertext file; if not, the description is plaintext, a plaintext process is started or the file is opened by using the existing plaintext process.
Then, whether the system is exited is checked, and if so, the system is exited.
By the embodiment, the problem that the plaintext process exists when the office software opens the ciphertext file, and the ciphertext content is possibly leaked due to the copying of the plaintext is avoided, and meanwhile, the problem that the plaintext is encrypted when the opened plaintext is edited in the ciphertext process is avoided. In addition, a ciphertext is opened, then the ciphertext is opened, if the security levels are the same, a plurality of programs can be opened, and the programs can be displayed by adopting only one program, wherein the specific strategy is determined by the ciphertext control strategy.
It should be noted that the steps illustrated in the flowcharts of the figures may be performed in a computer system such as a set of computer executable instructions, and that although a logical order is illustrated in the flowcharts, in some cases the steps illustrated or described may be performed in an order other than that illustrated herein.
