Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of computer, and in particular, to an application program updating method and device. BACKGROUND

[0002] When performing differential update for an application program such as a game, a server usually needs to send a corresponding differential package to a client according to a current installation package of the client. After receiving the differential package, the client can merge the differential package with the current installation package to generate a new installation package, and then update the application program with the newly generated installation package. When the server determines the current installation package of the client, the identification information of the current version installation package of the client needs to be obtained, and then the installation package is determined by using the identification information. In order to ensure that the newly generated installation package can correctly update the application program, the differential package needs to be accurately matched with the current installation package of the client. Therefore, the identification information of the installation package needs to be determined according to the files contained in the installation package.

[0003] Usually, the MD5 (Message-Digest Algorithm) value of each file in the installation package can be calculated, and then the identification information of the installation package can be generated according to the MD5 value of each file. However, the installation package of a large application program such as a game usually contains a large number of files, and calculating the MD5 value of each file will consume a large amount of time and is low in efficiency.

[0064] In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure clearer, the following will be combined with the accompanying drawings for the embodiments of the present disclosure to clearly and completely describe the technical solutions of the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, rather than all the embodiments. The components of the embodiments of the present disclosure described and shown in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present disclosure provided in the accompanying drawings is not intended to limit the scope of the claimed present disclosure, but only represents selected embodiments of the present disclosure. Based on the embodiments of the present disclosure, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present disclosure.

[0065] It should be noted that: similar reference numerals and letters represent similar items in the following drawings, therefore, once an item is defined in one drawing, it does not need to be further defined and explained in the subsequent drawings.

[0066] The term "and / or" in the present disclosure is only used to describe an association relationship, which means that there can be three relationships, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone. In addition, the term "at least one" in the present disclosure means any one of a plurality of combinations or any combination of at least two of a plurality of combinations, for example, including at least one of A, B and C can mean including any one or more elements selected from the set consisting of A, B and C.

[0067] It is found through research that when the server determines the differential package required by the client, the current installation package of the client is usually identified by using the identification information of the installation package. In order to ensure that the newly generated installation package can correctly update the application program, the differential package needs to be accurately matched with the current installation package of the client, and therefore the identification information of the installation package needs to be determined according to the files contained in the installation package. Usually, the MD5 value of each file in the installation package can be calculated, and then the identification information of the installation package can be generated according to the MD5 value of each file. However, the installation package of a large application program such as a game usually contains a large number of files, and calculating the MD5 value of each file will consume a large amount of time and is relatively low in efficiency.

[0068] Based on the above research, the present disclosure provides an application program updating method and device. The identification information corresponding to the installation package is generated based on the first target data under the signature path. Since the first target data includes channel information and signature information, the signature information itself is a unique identifier of the initial file of the installation package, and the channel information belongs to the information of the installation package customized by the channel. Therefore, the identification information generated according to the first target data can represent the signature part and the non-signature part of the current installation package at the same time, and can uniquely identify the whole current installation package. In addition, since the storage space occupation of the first target data is much smaller than that of the whole installation package, the speed of determining the identification information is improved without the need to calculate the MD5 value of all files, so that the server can quickly and accurately match the differential package corresponding to the installation package, and the efficiency is relatively high.

[0069] Referring to Figure 1 As shown in the figure, a flowchart of an application program updating method provided by an embodiment of the present disclosure is provided. The execution subject of the method can be a client, and the method includes steps S101-S104.

[0070] S101, based on the storage path of the signature information of the current version installation package of the target application program, the first target data under the storage path is obtained; the first target data includes the signature information of the current version installation package and channel information.

[0071] In this step, the client can obtain the current version installation package of the target application program after detecting that the target application program is published for updating, or after receiving the identification information acquisition request sent by the server, and obtain the first target data under the storage path of the signature information of the current version installation package.

[0072] The target application program can be an application program running under the Android system, and the format of the current version installation package can be an apk format, which can be stored in a preset directory of the client. The storage path of the signature information (signature path) can be a path in the current version installation package, and the signature information, channel information, etc. of the current version installation package can be stored in the path. The signature information is generated based on each file in the installation package and a preset signature algorithm when the installation package is published, and is added to the signature path in the installation package after the signature information is generated, and is used to verify the security and integrity of each file in the installation package to prevent the installation package from being tampered with. In addition to the signature information, the storage path of the signature information can also include channel information corresponding to the installation package, etc.

[0073] For different signature versions, the signature algorithm used when signing the installation package is different, and the corresponding signature path is also different. The target storage path corresponding to the current version installation package can be determined based on the signature version of the current version installation package and the storage paths of the signature information corresponding to the plurality of signature versions, and then the full amount of data in the target storage path is obtained, and the obtained full amount of data is taken as the first target data.

[0074] S102, based on the first target data, generating target identification information corresponding to the current version installation package.

[0075] In this step, a preset unique identification calculation algorithm can be used to calculate and process the first target data to generate a unique identification of the first target data, and the unique identification can be taken as the target identification information corresponding to the current version installation package. Specifically, data features of the first target data in one or more dimensions can be extracted, and the extracted data features can be processed according to an identification generation algorithm to obtain the target identification information.

[0076] For example, the data features can be MD5 values or hash values of the first target data.

[0077] S103, in the case where there is an update requirement, sending a difference package acquisition request to the server according to the target identification information, the difference package acquisition request carrying the target identification information, and receiving a target difference package fed back by the server based on the target identification information.

[0078] In this step, after the target identification information is generated, the update requirement can be detected, and when there is an update requirement, a difference package acquisition request can be sent to the server, the difference package acquisition request carrying the target identification information. The server can determine the target difference package matched with the target identification after receiving the difference package acquisition request containing the target identification information, and feed back the target difference package to the terminal device.

[0079] Here, the update requirement can be detecting a higher installation package than the current version, or detecting a defect in the current version installation package.

[0080] S104, updating the target application based on the target differential package and the current version installation package.

[0081] In this step, the client can update the current version installation package based on the target differential package to generate a target version installation package of the target application. Specifically, the target differential package and the current version installation package can be merged to generate a target version installation package of the target application corresponding to the target differential package. Then, the target application can be reinstalled using the target version installation package to achieve the update of the target application.

[0082] The embodiments of the present disclosure generate identification information corresponding to the installation package based on the first target data under the signature path, without calculating the MD5 values of all files. In the case where the identification information can completely reflect the files in the installation package, the server accurately matches the differential package corresponding to the installation package, and the efficiency is higher.

[0083] Referring to Figure 2 The execution subject of the method can be a server, and the method includes steps S201-S203, wherein:

[0084] S201, receiving a differential package acquisition request sent by a client, wherein the differential package acquisition request carries identification information corresponding to an installation package of a to-be-updated version.

[0085] In this step, the server receives the differential package acquisition request sent by the client, and the target identification information in the differential package acquisition request can be generated based on the first target data under the signature path of the previous version installation package by the client. The first target data includes signature information and channel information of the current version installation package of the target application.

[0086] S202, determining a target differential package corresponding to the identification information of the installation package uniquely from a pre-established mapping relationship table according to the identification information of the installation package, and sending the target differential package to the client, so that the client updates the target application using the target differential package.

[0087] The mapping relationship table is generated according to second target data under a storage path of signature information of at least one installation package of a to-be-updated version and a differential package corresponding to the at least one installation package of the to-be-updated version. The second target data includes signature information and channel information of the installation package of the to-be-updated version.

[0088] In this step, after the server obtains the target identification information, the server can determine the corresponding target differential package through the mapping relationship table, the mapping relationship table can reflect the mapping relationship between the differential package and the identification information, and the target differential package corresponding to the target identification information is screened out from the plurality of differential packages by using the mapping relationship.

[0089] The differential package is obtained based on the installation package of the target application program in two different versions. Since the channels and versions of the target application program installed on different clients can be different, to update the application program of different versions to the target version, the difference files between the installation package of each to-be-updated version and the installation package of the target version can be determined based on the installation package of at least one to-be-updated version of the target application program and the installation package of the target version of the target application program, and the differential package corresponding to the installation package of each to-be-updated version can be generated based on the difference files.

[0090] Specifically, the mapping relationship table can be generated through the following steps:

[0091] Obtaining the differential package between the installation package of the at least one to-be-updated version and the installation package of the target version;

[0092] For the installation package of the at least one to-be-updated version, obtaining second target data in the installation package of the to-be-updated version under the storage path of the signature information; the second target data includes the signature information and the channel information of the installation package of the to-be-updated version;

[0093] Generating the identification information corresponding to the installation package of the to-be-updated version based on the second target data;

[0094] Generating the mapping relationship table based on the identification information corresponding to the installation package and the differential package corresponding to the installation package.

[0095] The second target data and the first target data are both data under the storage path of the signature information in the corresponding installation package, and the description of the second target data can refer to the description of the first target data.

[0096] After obtaining the second target data, the identification information of the installation package corresponding to the second target data can be generated in the same way as the generation of the target identification information, and the mapping relationship between the differential package corresponding to the installation package and the corresponding identification information is established, to obtain the mapping relationship between the differential package and the identification information.

[0097] Since the generation manner of the target identification information is the same as the generation manner of the identification information of the installation package under the to-be-updated version, if the current version installation package of the client is the same as the installation package under the to-be-updated version, the target identification information is also the same as the identification information corresponding to the installation package under the to-be-updated version. Therefore, the mapping relationship between the identification information of the installation package under the to-be-updated version and the differential package is used to determine the corresponding relationship between the current version installation package of the client and the differential package, so as to filter out the target differential package corresponding to the current version installation package.

[0098] After the target differential package corresponding to the identification information of the installation package is determined, the target differential package can be sent to the client, so that the target version installation package corresponding to the target differential package is generated based on the target differential package and the current version installation package, and the target application program is updated by using the target version installation package.

[0099] The application program updating method provided in the embodiments of the present disclosure receives a differential package acquisition request sent by a client, and the differential package acquisition request carries identification information corresponding to an installation package of a to-be-updated version. Then, according to the identification information corresponding to the installation package, a target differential package uniquely corresponding to the identification information corresponding to the installation package is determined from a mapping relationship table established in advance, and the target differential package is sent to the client, so that the target application program is updated by using the target differential package. The mapping relationship table is generated according to second target data under a storage path of signature information of at least one installation package of a to-be-updated version and differential packages corresponding to the at least one installation package of the to-be-updated version. The second target data includes the signature information of the installation package of the to-be-updated version and channel information. In the embodiments of the present disclosure, the identification information corresponding to the installation package is generated based on data under the signature path, and the mapping relationship between the identification information and the differential package is established, so that the server can quickly locate the differential package required by the client.

[0100] Those skilled in the art can understand that the writing order of each step in the above-mentioned method of the specific embodiment does not mean a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of each step should be determined by its function and possible internal logic.

[0101] Based on the same inventive concept, the embodiments of the present disclosure also provide an application program updating device corresponding to the application program updating method. Since the principle of solving problems of the device in the embodiments of the present disclosure is similar to the above-mentioned application program updating method, the implementation of the device can be referred to the implementation of the method, and the repeated parts will not be described herein.
