And respectively comparing the differences of the first subfiles, the second subfiles and the third subfiles to obtain a plurality of difference subfiles, wherein the difference subfiles form a first difference data list.
Specifically, when a plurality of old version numbers exist between the current version number and the latest version number of the target application program, the old version numbers are respectively divided, and the file data of each old version number is divided into a plurality of first subfiles.
When difference comparison is carried out between the first subfile and the third subfile, the first subfiles with the old version numbers and the third subfiles are compared respectively, one old version number serves as an example, after the file data of the version numbers are divided, the file data of the version numbers comprise the first subfiles, the first subfiles and the third subfiles are compared respectively to obtain difference data between the first subfiles and the third subfiles, and the difference data form a difference data list between the version numbers and the latest version. Similarly, the file data of the latest version number and the file data of the current version number are subjected to the above operation to obtain difference data between the latest version number and the current version number, and the difference data between each old version and the current version number and the difference data between the latest version number and the current version number form a first difference data list together.
Further, as an optional embodiment of the present application, the segmenting the file data of the target application includes:
and segmenting the file data according to the writing logic information and the functional partition information of the file data of the target application program to obtain a plurality of difference subfiles. Wherein the data packet of each difference subfile does not exceed a predetermined value.
Specifically, taking the game-class application as an example, the game-class application includes many functional modules, such as a newsletter function, an equipment purchasing function, an equipment synthesizing function, and the like, and the modules are divided and divided, so that each sub-file obtained by dividing the corresponding module only includes data information of one functional module. When downloading a patch package of an application, the downloading of the patch package is usually performed by using 2M as a node, and in the embodiment of the present invention, when performing file data division, the size of the subfile is set to a predetermined value (the predetermined value may be selected as 2M in the present invention).
S13: and screening out repeated difference files from the first difference data list, and generating a first patch package according to a target first difference data list obtained by screening out the repeated difference files from the first difference data list.
Specifically, the step of screening out duplicate difference files from the first difference list refers to the step of screening out the difference files with duplicate data in each difference file, and finally only one difference file is reserved in the duplicate difference files. And the problem that the patch package is overlarge due to repeated compression of repeated difference files is avoided.
As an alternative embodiment of the present invention, step S13 includes:
similarity analysis is performed on each difference subfile.
If a plurality of same-name target difference subfiles with the similarity exceeding the threshold exist, one same-name target difference subfile is reserved, other repeated same-name target difference subfiles are screened out, and the repeated difference files comprise the plurality of same-name target difference subfiles.
Specifically, similarity analysis is carried out on each difference subfile, specifically, the difference subfiles are analyzed to obtain binary data, after the similarity analysis is carried out, the uniquely determined similarity exists between the difference subfiles, if the similarity exceeds a threshold value, the repeatability between the difference subfiles is high, only one same-name target difference subfile is reserved in the repeated same-name target difference subfiles, and the repeated same-name target difference subfiles are screened out, so that the problems that a user repeatedly downloads the repeated same-name target difference files, the downloading time is too long, and the flow is consumed are solved.
S14: and sending the first patch package to the client so that the client acquires and downloads the first patch package.
Specifically, as an alternative embodiment of the present application, the step S14 of obtaining and downloading the first patch package by the client includes:

and the client downloads the difference files in the target first difference data list in the first patch package in a multithread mode.
Specifically, the first patch package includes a target first difference data list, the target first difference data list includes a plurality of difference sub-files, and after the client receives the first patch package, each difference file in the target first difference data list in the first patch package can be downloaded in a multi-thread manner, so that the time for a user to download the patch package is further shortened.
If the historical version number of the target application does not exist between the current version number and the latest version number of the target application, the method of upgrading the current version number of the target application to the patch package with the latest version number may be the same as the conventional method, or alternatively, as shown in fig. 2, after step S11 is executed, if the historical version number of the target application does not exist, the process may proceed to step S15.
S15: and carrying out difference comparison on the file data of the current version number of the target application program and the file data of the latest version number of the target application program to obtain a second difference data list.
S16: and generating a second patch package by using the second difference data list.
Specifically, the comparison method of the difference between the file data of the current version number and the latest version number may refer to the comparison method in step S12, and details of the embodiment of the present invention are not repeated herein.
In the method for downloading an application patch package disclosed in embodiment 1 of the present invention, when a plurality of historical version numbers exist between the current version number and the latest version number of a target application program, file data of the current version number of the target application program and file data of each historical version number are respectively compared with the latest version number to generate a first difference data list, and in the first difference data list, a difference file between each version number and the latest version number of the target application program is included, and when upgrading across versions, one patch package can be directly upgraded to the latest version, thereby avoiding generating a plurality of upgrade sequences and a plurality of upgrade resource packages, reducing the size of the patch package, and in addition, screening out duplicate difference files in the difference file formed between each file data of an old version number and each file data of a new version number of the target application program, the repeated difference files are prevented from being packaged when the first patch package is generated, and the size of the first patch package is further reduced.

After the client receives and downloads the first patch package, the client needs to perform data verification on the first patch package, so as to avoid that all data in the first patch package are downloaded again after some part of the first patch package fails to perform data verification, and the flow and time of a user are consumed. As an alternative embodiment of embodiment 2 of the present invention, as shown in fig. 3, after step S14 is executed, the method further includes:
s20: the client performs data verification on the first patch package, and if the first patch package fails to be verified, the process proceeds to step S21.
S21: and the client analyzes the target difference file which is not checked to pass in the first patch package.
S22: based on the target difference file, the client sends a second repair request to the remote server.
Specifically, the second repair request includes a target differential file that is not verified, after the remote server receives the second repair request, the remote server parses data in the target differential file for the target differential file that is not verified in the second repair request, and performs difference comparison between file data of the version number of the target application program corresponding to the target differential file and file data of the latest version number, so as to redetermine a new differential file corresponding to the target differential file for downloading by the client. Therefore, the difference files in the target first difference list passing the verification do not need to be downloaded repeatedly, the time and the flow of a user are saved, and the repairing efficiency of the application program is improved. The user experience is improved.
In the method for downloading the application patch package disclosed in embodiment 2 of the present invention, when a history version number exists between the current version number and the latest version number of the target application program, the file data of the current version number of the target application program and the file data of the history version number are respectively compared with the latest version number to generate a first difference data list, in which the difference files between each version number and the new version number of the target application program are included, and it is not necessary to compare the file data of each old version number differently, thereby avoiding the generation of a plurality of upgrade sequences and a plurality of upgrade resource packages, reducing the size of the patch package, and in addition, screening out the repeated difference files in the difference files formed between the file data of each old version number of the target application program and the file data of the new version number, the repeated difference files are prevented from being packaged when the first patch package is generated, and the size of the first patch package is further reduced. Therefore, the resource size of the first patch package is small, so that the downloading time of the patch package and the downloading flow required by downloading the patch package can be shortened when the first patch package is downloaded, and the downloading efficiency of the patch package and the repairing efficiency of the application program are improved.
