In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Referring to fig. 1, a flowchart illustrating steps of an embodiment of a file processing method according to the present invention is shown, which may specifically include the following steps:
step 101, judging whether the dynamic library loading folder has the read-write permission.
In this embodiment, the file processing apparatus may be an apparatus for implementing program installation, and the apparatus implements installation of a high-privilege program by processing and controlling related folders and files.
The dynamic library loading folder is a folder for loading a dynamic library, and the dynamic library loaded into the folder can be automatically mounted into a certain program after subsequent processing, which is specifically referred to in the following description.
In this step, the file processing apparatus first checks the authority of the dynamic library to load the folder, and determines whether the authority of the folder is a readable and writable authority.
If the dynamic library loading folder does not have the read-write permission, executing the steps 102-103; if the read-write permission exists, step 103 is directly executed.
The process of modifying the authority of the dynamic library loading folder can actively manufacture a system bug by deleting important configuration files in the system and link the configuration files to the dynamic library loading folder, so that the system can automatically modify the authority of the dynamic library loading folder into a read-write authority when repairing the bug after restarting.
After the modification to the read/write permission, step 103 is performed.
103, storing an installation service file for installing a specified program into the dynamic library loading folder; wherein the authority of the designated program is higher than the authority given to the application program by the operating system.
And when the authority of loading the folder of the dynamic library is the read-write authority, the installation service file can be placed into the loading folder of the dynamic library.
The installation service file is used for installing a designated program, the designated program is a high-authority program, the authority of the designated program is higher than the authority of an application program given by an operating system, and for the iOS operating system, the authority of the designated program is higher than the authority of an application program file of the iOS operating system.
And 104, restarting the positioning service to mount the installation service file in the positioning service.
The restarting of the location service may specifically be performing a restart method in location service management to restart the location service. After the positioning service is restarted, the installation service file in the dynamic library loading folder can be automatically mounted in the positioning service.
After the installation service file is successfully mounted, the installation service file can be called to install the high-authority designated program.
According to the embodiment of the invention, the installation service file is mounted in the positioning service, so that the installation service file can be used for installing the high-authority program, and the function of installing the high-authority program through the low-authority program is realized. The method does not need to crack the installation program of the system to install the high-authority program, breaks through the limitation of program installation, expands the program popularization channel, is simple and convenient to operate, and reduces the difficulty of program installation.
In another embodiment of the present invention, a process of modifying the authority of loading the dynamic library into the folder into the readable and writable authority, as shown in fig. 2, may specifically include the following steps:
In this embodiment, the file processing apparatus first finds a location service configuration file in the system, and then deletes the file, so that the system generates a vulnerability.
In order to modify the read-write permission of the dynamic library loading folder, the step links the positioning service configuration file to the dynamic library loading folder.
The restarting of the location service may specifically be performing a restart method in location service management to restart the location service. After the positioning service is restarted, the system can automatically modify the authority of loading the folder of the dynamic library into the read-write authority when the bug is repaired.
According to the embodiment of the invention, the installation service file can be written into the dynamic library loading folder only by modifying the read-write permission of the dynamic library loading folder, so that the installation service file can be hung in the positioning service program after the positioning service is restarted.

If the read-write permission exists, executing steps 305-308; if the read-write permission does not exist, executing steps 302-304, and firstly modifying the permission of/Library/Mobile subsystem/dynamic libraries as the read-write permission.
In this step, the location service configuration file is:
a/var/mobile/Library/Preferences/com. applet.
After the file is deleted, step 303 is performed.
link/var/mobile/Library/Preferences/com. applet. located. plist files to/Library/mobile subsystem/dynamic libraries.
And executing a shutdown daemon method in the CLLocation manager to restart the located service.
After the positioning service is restarted, the permission of the Library/Mobile subsystem/dynamic libraries can be modified into the read-write permission, and then the steps 305-308 are executed.
In this embodiment, the installation service file is a helloworld.dylib file, which is a program responsible for installing the specified program. In this step, the helloworld. dynamic is written into/Library/MobileSubstrate/dynamic libraries.
Wherein the authority to specify the program is higher than the authority of IPA (iPhone application).
And executing a shutdown daemon method in the CLLocation manager to restart the located service.
After the location service is restarted, helloworld.dylib can be mounted in the location service, so that the specified program can be installed with high authority.
After restarting, the DEB program package of the appointed program can be installed by using HelloWorld.
At step 308, the designated program is quickly restarted to enable its functionality.
After the execution program is installed, the specified program is quickly restarted, so that the function thereof can be made effective.
