technical field

The present disclosure relates to the field of computer technology, in particular, to an application program updating method and device.

Background technique

When performing differential updates for applications such as games, the server usually needs to send the corresponding differential package to the client according to the current installation package of the client. After receiving the differential package, the client can merge the differential package with the current installation package. , generate a new installation package, and then update it with the newly generated installation package. When the server determines the current installation package of the client, it needs to obtain the identification information of the current version installation package of the client, and then use the identification information to determine the installation package. In order to ensure that the newly generated installation package can correctly update the application program, the differential package needs to exactly match 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.

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

After research, it is found that when the server determines the differential package needed by the client, it usually uses the identification information of the installation package to identify the current installation package of the client. In order to ensure that the newly generated installation package can update the application program correctly, the differential package needs to be shared with the 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-scale application such as a game usually contains a large number of files, and calculating the MD5 value of each file will consume a lot of time, and the efficiency is low.

Based on the above research, this disclosure provides a method and device for updating an application program. 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 It is the unique identification of the initial file of the installation package, and the channel information belongs to the information after the installation package is customized by the channel, so that the identification information generated according to the first target data can simultaneously represent the signature part and the non-signature part of the current installation package , to uniquely identify the current installation package as a whole, and since the storage space occupied by the first target data is much smaller than that of the entire installation package, the speed of determining the identification information does not need to calculate the MD5 values of all files It is improved, so that the server can quickly and accurately match the differential package corresponding to the installation package, and the efficiency is high.

Referring to FIG. 1 , it is a flow chart of an application update method provided by an embodiment of the present disclosure. The subject of execution of the method may be a client, and the method includes steps S101 to S104, wherein:

In this step, the client can obtain the current version installation package of the target application after detecting that the target application releases an update, or after receiving the identification information acquisition request sent by the server, and obtain the storage of the signature information of the current version installation package The first target data under the path.

Wherein, the target application program can be the application program running under the Android system, and the format of the installation package of the current version can be the apk format, which can be stored in the preset directory of the client; the storage path (signature path) of the signature information can be the current version A path in the installation package, under which the signature information and channel information of the current version of the installation package can be stored. The signature information is generated based on each file in the installation package and the preset signature algorithm when the installation package is released, and is added to the signature path in the installation package after the signature information is generated to verify each file in the installation package The security and integrity of the installation package are prevented from being tampered with. In addition to the signature information, the storage path of the signature information may also include channel information corresponding to the installation package.

For different signature versions, the signature algorithms used when signing the installation package are different, and the corresponding signature paths are also different. The signature version of the current version of the installation package and the storage paths of the signature information corresponding to multiple signature versions can be used to determine the signature. The target storage path corresponding to the installation package of the current version is described, and then the full amount of data under the target storage path is obtained, and the obtained full amount of data is used as the first target data.

S102. Based on the first target data, generate target identification information corresponding to the current version installation package.

In this step, the first target data can be calculated and processed by using a preset unique identifier calculation algorithm to generate a unique identifier of the first target data, and the unique identifier can be used as the corresponding identifier of the current version installation package. Target identification information. Specifically, data features of the first target data in one or more dimensions may be extracted, and the extracted data features may be processed according to an identification generation algorithm to obtain target identification information.

Exemplarily, the data feature may be an MD5 value or a hash value of the first target data.

S103. When there is an update requirement, send a differential packet acquisition request to the server according to the target identification information, the differential packet acquisition request carries the target identification information, and receive feedback from the server based on the target identification information The target differential package.

In this step, after the target identification information is generated, the update requirement can be detected. When there is an update requirement, a differential packet acquisition request can be sent to the server. The differential packet acquisition request carries the target identification information. After the differential packet acquisition request of the identification information, the target differential packet matching the target identifier can be determined, and the target differential packet can be fed back to the terminal device.

Here, the update requirement may be the detection of a release of an installation package higher than the current version, or the detection of a defect in the current version of the installation package.

S104. Update the target application program based on the target differential package and the current version installation package.

In this step, the client may update the current version installation package based on the target differential package to generate the target version installation package of the target application, specifically, the target differential package may be merged with the current version installation package to generate a target version installation package of the target application program corresponding to the target differential package, and then, the target version installation package can be used to reinstall the target application program to implement an update of the target application program.

The embodiment of the present disclosure generates the 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, and enables the server to accurately Match the differential package corresponding to the installation package, which is more efficient.

Referring to FIG. 2 , it is a flow chart of another method for updating an application program provided by an embodiment of the present disclosure. The subject of execution of the method may be a server, and the method includes steps S201 to S203, wherein:

S201. Receive a differential package acquisition request sent by a client, where the differential package acquisition request carries identification information corresponding to an installation package of a version to be updated.

The target identification information may be generated by the above-mentioned client based on the first target data under the signature path of the previous version installation package. The first target data includes signature information and channel information of the current version installation package of the target application program.

S202. According to the identification information corresponding to the installation package, determine the target differential package uniquely corresponding to the identification information corresponding to the installation package from the pre-established mapping table, and send the target differential package to the client , so that the client uses the target differential package to update the target application program.

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

Since the generation method of the above target identification information is the same as that of the identification information of the installation package under the version to be updated, if the installation package of the current version of the client is the same as the installation package of the version to be updated, the target identification information and the installation package to be updated The identification information corresponding to the installation package under the updated version is also the same, therefore, use the mapping relationship between the identification information of the installation package under the version to be updated and the differential package to determine the corresponding relationship between the current version installation package and the differential package of the client , so as to filter out the target differential package corresponding to the current version installation package.

After determining the target differential package uniquely corresponding to the identification information of the installation package, the target differential package can be sent to the client, so that the client generates a target version installation package corresponding to the target differential package based on the target differential package and the current version installation package, and then Update the target application with the target version installation package.

The method for updating an application program provided by an embodiment of the present disclosure receives a differential packet acquisition request sent by a client, and the differential packet acquisition request carries identification information corresponding to an installation package to be updated; then, according to the identification information corresponding to the installation package , determining from a pre-established mapping relationship table a target differential package uniquely corresponding to the identification information corresponding to the installation package, and sending the target differential package to the client, so that the client uses the target The difference package updates the target application program; wherein, the mapping relationship table is based on the second target data under the storage path of the signature information of at least one installation package of the version to be updated, and the corresponding difference of the installation package of the at least one version of the installation package to be updated Package generation; the second target data includes signature information and channel information of the installation package of the version to be updated.
