In the embodiment, the terminal device 200 is in communication connection with the application store server 300, and the terminal device 200 may be, but is not limited to, a PC, a smart phone, a tablet computer, a portable computing device, and the like.
In this embodiment, the APP store server 300 is communicatively connected to the development platform 400, and the development platform 400 issues the developed APP to the APP store server 300 to be displayed to the user through the APP store server 300.
First embodiment
Referring to fig. 2, fig. 2 is a flowchart illustrating a procedure of an APP downloading method according to a first embodiment of the present invention. The method is applied to an APP service system 10, and the APP service system 10 includes a terminal device 200, a gateway device 100 and an application store server 300 which are connected in a communication manner. The APP downloading method is suitable for an apple system using an IOS. The detailed flow of the APP downloading method is described below.
In step S120, the terminal device 200 initiates an APP download request to the APP store server 300.
In this embodiment, when the terminal device 200 needs to download the APP, it needs to first send an authentication request to the APP store server 300 and purchase the APP protocol. The main interaction at this stage is the HTTPS protocol, which is an HTTP channel targeted for security, and the HTTPS protocol adds the SSL protocol based on HTTP, and establishes an information security channel to ensure the security of data transmission.
In this embodiment, after the authentication is passed, the terminal device 200 acquires the APP download address, and requests the APP download to the APP store server 300 through the APP download address.
Step S130, the APP store server 300 issues an HTTP message and an APP file according to the APP download request.
In this embodiment, the APP store server 300 receives an APP download request initiated by the terminal device 200, and issues an HTTP message and an APP file according to the APP download request. Wherein the APP files comprise at least one different version of APP file.
Step S140, the gateway device 100 processes the HTTP message and the APP file according to a preset APP cache policy, and selects a target version APP file for caching.
Referring to fig. 3, fig. 3 is a flowchart illustrating sub-steps of step S140 shown in fig. 2 according to a first embodiment of the present invention. The step S140 includes a substep S141, a substep S142, and a substep S143.
In the substep S141, the gateway device 100 intercepts the HTTP message and the APP file sent by the APP store server 300.
In this embodiment, when the APP store server 300 issues the HTTP message and the APP file, the gateway device 100 intercepts the issued HTTP message and APP file to perform identification and analysis, so that the HTTP message and APP file are not directly issued to the terminal device 200.
And in the substep S142, the gateway device 100 analyzes and identifies the intercepted HTTP message and APP file, and identifies a target version APP file to be cached.
Referring to fig. 4, fig. 4 is a flowchart illustrating a sub-step S142 shown in fig. 3 according to a first embodiment of the present invention. The substep S142 includes substep S1421, substep S1422, and substep S1423.
In substep S1421, the gateway device 100 obtains at least one to-be-identified characteristic character string from the HTTP message and/or at least one APP file of a different version.
In this embodiment, since a URL (Uniform Resource Locator) in the HTTP message corresponding to the APP file generally ends with ". signed. dpkg. ipa", which HTTP requests are to download the APP file can be determined by detecting the URL, and in the IOS, the APP file is a zip compressed file. Therefore, which version of APP file is the APP file needing to be cached can be identified according to the HTTP message and/or the APP file.
In this embodiment, the manner of obtaining at least one to-be-identified feature string from the HTTP message and/or at least one APP file of a different version includes:
1. gateway device 100 caches at least one APP file of different versions, decompresses at least one cached APP file, and acquires a corresponding to-be-identified characteristic string according to the decompressed APP file.
In this embodiment, the to-be-identified characteristic string may be a name of an APP corresponding to the APP file. The path name in the zip compressed file will contain the name of the APP, and the path is typically "/Playload/< APP name >/", for example: APP/"contained in APP of line E of the work bank. And, the name of this APP is irrelevant to the model and IOS version of the apple terminal device 200. Thus, by decompressing the zip compressed file, the APP name therein can be found.
In this embodiment, the gateway device 100 obtains the corresponding stream information during the process of decompressing different zip compressed files by decompressing zip compressed files of different versions corresponding to APPs, and generates the corresponding feature character string to be identified according to the obtained stream information.
2. And the gateway device 100 acquires the characteristic character string to be identified according to the HTTP message.
In this embodiment, since the speed of caching the whole APP file and then decompressing the whole APP file is relatively slow, the gateway device 100 may obtain the feature character string to be identified according to the HTTP message. Usually, the position of the APP name is within the first 1KB range of the stream information of the downloaded APP, and the gateway device 100 may obtain the feature string to be identified from the stream information of the downloaded APP according to the HTTP message.
In the substep S1422, the gateway device 100 compares each to-be-recognized feature character string with a preset feature character string.
In this embodiment, the gateway device 100 may compare each feature string to be recognized with a preset feature string to obtain a corresponding similarity, and if there is a similarity obtained by comparing a feature string to be recognized with the preset feature string that is greater than a preset similarity (for example, 98%), it may be determined that the feature string to be recognized is the same as the preset feature string. The preset characteristic character string can be preset according to APP parameters of user requirements, and the preset similarity can also be set according to actual needs.
In the substep S1423, if a to-be-identified characteristic character string is identical to the preset characteristic character string, it is determined that the APP file corresponding to the to-be-identified characteristic character string is the target version APP file to be cached.
In sub-step S143, the gateway device 100 performs caching processing on the identified target version APP file.
In this embodiment, the gateway device 100 only caches the identified APP files of the target version, only caches the APP needed by the user accurately, and does not cache all APP files of different versions sent by the APP store server 300. The occupancy rate of the disk is reduced, the bandwidth consumption is reduced, and better user experience is achieved.
Referring again to fig. 2, the method further includes:
step S150, the terminal device 200 downloads the target version APP file from the gateway device 100 to complete APP downloading.
In this embodiment, after the gateway device 100 finishes caching the target version APP file, the terminal device 200 may directly download the target version APP file from the gateway device 100 to finish APP downloading. The downloading is not required to be carried out through the application store server 300, the downloading speed is high, and the user experience is good.
Referring to fig. 5, fig. 5 is a second flowchart illustrating steps of an APP downloading method according to a first embodiment of the present invention. The method further comprises the following steps:
step S160, when the APP of the version corresponding to the target version APP file is requested to be downloaded again, the terminal device 200 requesting to download directly downloads the target version APP file from the gateway device 100, so as to complete APP downloading.
In this embodiment, when the terminal device 200 requests to download the target version APP file again, or another terminal device 200 having the same hardware version and software version as those of the terminal device 200 requests to download the target version APP file, the terminal device 200 requesting to download may directly download the target version APP file from the gateway device 100 to complete APP downloading.
Step S110, the development platform 400 generates at least one APP file of different version according to the version type of the terminal device 200, and issues the at least one APP file of different version to the APP store server 300.
In this embodiment, in order to meet the use requirement of the user, the development platform 400 may compile at least one APP with different versions according to the hardware version and/or the software version of the terminal device 200 for the same APP, and issue the at least one APP file with different versions to the APP store server 300 for the user to select.
