Example two
Fig. 2 is a flowchart of an application image installation method according to a second embodiment of the present invention.
The application program mirror image installation method is applied to the terminal, and specifically comprises the following steps, the sequence of the steps in the flow chart can be changed according to different requirements, and certain steps can be omitted.
S21, acquiring an application program installation package image file issued by the server.
In this embodiment, when the terminal needs to install or update the application program, an installation request may be sent to the server, and the server is requested to send an application program installation package image file corresponding to the installation request.
And the server responds to the installation request, transmits an application program installation package image file to the terminal, and the terminal receives the application program installation package image file.
S22, decrypting the application program installation package image file to obtain the application program image file and the first check value.
After receiving the application program installation package image file, the terminal can decrypt the application program installation package image file (for example, input a decryption password) according to an encryption and decryption protocol which is negotiated with the server in advance, and after decrypting, the application program image file and the first check value can be obtained.
S23, calculating a second check value of the application program image file.
In this embodiment, a Message-Digest Algorithm (md5 code) may be stored in advance, and the MD5 code of the application image file is calculated according to the preset Message-Digest Algorithm, and the calculated MD5 code is used as the second check value of the application image file.
S24, judging whether the first check value is the same as the second check value.
In this embodiment, the terminal compares the first check value with the second check value, and determines whether the first check value is the same as the second check value, so as to determine whether the application program image file issued by the server is correct.
When the first check value is the same as the second check value, the application program issued by the server is indicated to be correct in frequent files, and S25 is executed; otherwise, when the first check value is different from the second check value, the fact that the files of the application programs issued by the server are wrong is indicated.
And S25, when the first check value is the same as the second check value, the application program mirror image file is mounted to an application program installation catalog.
In this embodiment, if the terminal determines that the first check value is the same as the second check value, the application image file is mounted to the application installation directory.
Mount (mount) refers to a process by which a computer file and directory on a storage device (such as a hard disk, CD-ROM, or shared resource) is made available to a user for access through the computer's file system by the operating system. The terminal directly accesses the application image file through the application installation catalog by mounting the application image file in the application installation catalog without decompression processing.
S26, installing the application program according to the application program image file.
The terminal accesses the application image file in the application program installation catalog, starts the installation process and installs the application program.
After the terminal installs the application program, a notification of successful application program installation can be reported to the server.
In a preferred embodiment, the method further comprises:
acquiring an application program mounting identifier;
the mounting the application image file to the application installation catalog comprises the following steps: setting an application program mounting mode according to the application program mounting identification; and mounting the application image file to an application installation catalog according to the application program mounting mode.
The terminal can acquire the application program mounting identifier while acquiring the application program mounting package image file, and can acquire the application program mounting identifier after or before acquiring the application program mounting package image file.
It should be understood that if the terminal does not acquire the application program mounting identifier, the application program image file may be directly mounted to the application program installation directory; and if the terminal acquires the application program mounting identification, the terminal needs to mount the application program image file according to the set application program mounting mode.
Specifically, when the terminal obtains the application program mounting identifier as the first mounting identifier, the mounting mode is correspondingly set to be the first mounting mode, and the first mounting mode can be a read-only mode, namely, after the application program image file is mounted to the application program mounting catalog, only the file of the application program can be read and the file of the application program can not be modified at all when the application program is operated later. When the terminal obtains the application program mounting identifier as a second mounting identifier, the mounting mode is correspondingly set to be the second mounting mode, and the second mounting mode can be a read-write mode, namely, after the application program image file is mounted to the application program mounting catalog, the file of the application program can be read and modified in the follow-up running of the application program.
Preferably, when the terminal obtains the application program installation identifier as the second installation identifier, and after the application program image file is installed in the application program installation directory, the method further includes:
And backing up the application program image file and storing the application program image file in a read-only mode.
When the terminal detects that the user modifies the file of the application program, the modified file is stored as a read-write mode. Therefore, the application program image file can not be truly modified, and when the application program runs in error, the application program can be reinstalled according to the backed-up application program image file.
In a preferred embodiment, when the first check value is different from the second check value, the method further comprises:
after a preset time period, acquiring the application program installation package image file issued by the server again; or alternatively
And reporting the application program installation failure notification to the server.
In some practical applications, because the signal quality of the communication link may be poor when the terminal and the server communicate, the acquired image file of the application program installation package may be in error, and therefore, when the terminal determines that the first check value is different from the second check value, the terminal may acquire the image file of the application program installation package from the server again at intervals.
In other embodiments, if the terminal determines that the first check value is different from the second check value, the terminal may directly report an application installation failure notification to the server, so as to notify the server that the application installation package image file is in error.
In summary, according to the application program installation method provided by the invention, the application program installation package image file issued by the server is obtained, the application program image file and the first check value are obtained after decryption, the second check value of the application program image file is calculated, when the first check value is the same as the second check value, the application program image file is installed in the application program installation catalog, and finally the application program is installed according to the application program image file. The installation of the application program can be completed by acquiring the image file of the application program installation package and installing the image file to the installation catalog, and the process of decompressing the application program installation package by the terminal can be omitted because the image file of the application program installation package rather than the application program installation package is downloaded, so that the efficiency of installing the application program is improved; in addition, the integrity of the application program image file is checked through the check value of the application program image file, so that the check of all the decompressed files one by one is quicker and quicker, and the correctness and the integrity of the application program installation package image file are effectively ensured.

Fig. 4 is a schematic functional block diagram of an application mirror image installation device according to an embodiment of the invention.
In some embodiments, the application image installation device 40 runs in a terminal. The application image installation means 40 may comprise a plurality of functional modules consisting of program code segments. Program code for each program segment in the application program mirror image installation device 40 may be stored in a memory of the terminal and executed by the at least one processor to perform (see fig. 2 for details) mirror image installation of the application program.
In this embodiment, the application image installation apparatus 40 may be divided into a plurality of functional modules according to the functions performed by the application image installation apparatus. The functional module may include: the system comprises an acquisition module 401, a decryption module 402, a calculation module 403, a judgment module 404, a mounting module 405, an installation module 406, a backup module 407 and a reporting module 408. The module referred to in the present invention refers to a series of computer program segments capable of being executed by at least one processor and of performing a fixed function, stored in a memory. In the present embodiment, the functions of the respective modules will be described in detail in the following embodiments.
And the obtaining module 401 is configured to obtain an image file of the application program installation package issued by the server.
In this embodiment, when the terminal needs to install or update the application program, an installation request may be sent to the server, and the server is requested to send an application program installation package image file corresponding to the installation request.
And the server responds to the installation request, transmits an application program installation package image file to the terminal, and the terminal receives the application program installation package image file.
And the decryption module 402 is configured to decrypt the application installation package image file to obtain an application image file and a first check value.
After receiving the application program installation package image file, the terminal can decrypt the application program installation package image file (for example, input a decryption password) according to an encryption and decryption protocol which is negotiated with the server in advance, and after decrypting, the application program image file and the first check value can be obtained.
A calculation module 403, configured to calculate a second check value of the application image file.
In this embodiment, a Message-Digest Algorithm (md5 code) may be stored in advance, and the MD5 code of the application image file is calculated according to the preset Message-Digest Algorithm, and the calculated MD5 code is used as the second check value of the application image file.
A determining module 404, configured to determine whether the first check value is the same as the second check value.
In this embodiment, the terminal compares the first check value with the second check value, and determines whether the first check value is the same as the second check value, so as to determine whether the application program image file issued by the server is correct.
And the mounting module 405 is configured to mount the application image file to an application installation directory when the first check value is the same as the second check value.
In this embodiment, the terminal determines that the first check value is the same as the second check value, which indicates that the frequent file of the application program issued by the server is correct, and then mounts the image file of the application program to the application program installation directory.
Mount (mount) refers to a process by which a computer file and directory on a storage device (such as a hard disk, CD-ROM, or shared resource) is made available to a user for access through the computer's file system by the operating system. The terminal directly accesses the application image file through the application installation catalog by mounting the application image file in the application installation catalog without decompression processing.
And the installation module 406 is used for installing the application program according to the application program image file.
The terminal accesses the application image file in the application program installation catalog, starts the installation process and installs the application program.
In a preferred embodiment, the obtaining module 401 is further configured to obtain an application mount identifier.
The mounting module 405 is further configured to set an application mounting mode according to the application mounting identifier; and mounting the application image file to an application installation catalog according to the application program mounting mode.
The terminal can acquire the application program mounting identifier while acquiring the application program mounting package image file, and can acquire the application program mounting identifier after or before acquiring the application program mounting package image file.
It should be understood that if the terminal does not acquire the application program mounting identifier, the application program image file may be directly mounted to the application program installation directory; and if the terminal acquires the application program mounting identification, the terminal needs to mount the application program image file according to the set application program mounting mode.
Specifically, when the terminal obtains the application program mounting identifier as the first mounting identifier, the mounting mode is correspondingly set to be the first mounting mode, and the first mounting mode can be a read-only mode, namely, after the application program image file is mounted to the application program mounting catalog, only the file of the application program can be read and the file of the application program can not be modified at all when the application program is operated later. When the terminal obtains the application program mounting identifier as a second mounting identifier, the mounting mode is correspondingly set to be the second mounting mode, and the second mounting mode can be a read-write mode, namely, after the application program image file is mounted to the application program mounting catalog, the file of the application program can be read and modified in the follow-up running of the application program.
The backup module 407 is configured to backup and store the application image file in a read-only mode when the terminal obtains the application mounting identifier as the second mounting identifier and after the application image file is mounted in the application installation directory.
When the terminal detects that the user modifies the file of the application program, the modified file is stored as a read-write mode. Therefore, the application program image file can not be truly modified, and when the application program runs in error, the application program can be reinstalled according to the backed-up application program image file.
In a preferred embodiment, the obtaining module 401 is further configured to obtain, when the first check value is different from the second check value, the application installation package image file issued by the server again after a preset period of time.
A reporting module 408, configured to report an application program installation success notification to the server when the first check value is the same as the second check value; or the server is used for reporting the application program installation failure notice when the first check value is different from the second check value.
In some practical applications, because the signal quality of the communication link may be poor when the terminal and the server communicate, the acquired image file of the application program installation package may be in error, and therefore, when the terminal determines that the first check value is different from the second check value, the terminal may acquire the image file of the application program installation package from the server again at intervals.
In other embodiments, if the terminal determines that the first check value is different from the second check value, the terminal may directly report an application installation failure notification to the server, so as to notify the server that the application installation package image file is in error.
In summary, according to the application program installation device provided by the invention, the application program installation package image file issued by the server is obtained, the application program image file and the first check value are obtained after decryption, the second check value of the application program image file is calculated, when the first check value is the same as the second check value, the application program image file is installed to the application program installation catalog, and finally the application program is installed according to the application program image file. The installation of the application program can be completed by acquiring the image file of the application program installation package and installing the image file to the installation catalog, and the process of decompressing the application program installation package by the terminal can be omitted because the image file of the application program installation package rather than the application program installation package is downloaded, so that the efficiency of installing the application program is improved; in addition, the integrity of the application program image file is checked through the check value of the application program image file, so that the check of all the decompressed files one by one is quicker and quicker, and the correctness and the integrity of the application program installation package image file are effectively ensured.
