< first embodiment >

Fig. 2 shows a channel package distribution method according to the first embodiment. The method may be implemented, for example, by the distribution server 1000 in fig. 1. In this embodiment, the channel package distribution method may include the following steps S210 to S240:

step S210, a first source installation package of the distributed application is received.

In this embodiment, the distributed application may be one application in the distribution server, or may be one application that is sent to the distribution server by the third party server, which is not limited herein. The third party is, for example, a CP (Content Provider), that is, a Provider that provides service Content, and the Content may be various media Content such as text, image, audio and video. The application may be a gaming application, streaming media application, or other application, among others.

In this embodiment, the first source installation package is an installation package containing the content of the distributed application, and the installation package may be an application package in the distribution server, or may be an application package provided by a third party server, for example, an APK (Android application package ) for a game.

Step S220, filling a setting field in a designated position of the first source installation package, and generating a second source installation package.

In this embodiment, the setting field may be a field for writing channel information, and the field may be a setting byte length, for example, a byte length of 1K,2K, or 4K, which is not limited herein. Wherein, the channel provides the user with the service of application downloading and updating, the channel information can be the name, the number of downloading and updating, and the like information representing the service, and the invention is not limited herein.

In some examples, the signature manner of the first source installation package is classified into a V1 signature, a V2 signature, a V3 signature, and the like.

V1 signature, that is, JAR (Java Archive) signature, records signature information by adding META-INF directory in APK file, requires modification of data area, central directory and central directory end record.

Taking fig. 3 as an example, the first source installation package is signed by V1, and the first source installation package may include: the contents of the ZIP entry (Content of ZIP entries), the ZIP central Directory (central Directory), and the ZIP central Directory end (End of Centry Directory). Wherein the ZIP central directory end (End of Centry Directory) comprises: magic value, current disk number, disk number of CD (center Directory) start position, number of CD recorded on disk, total number of CD Directory structures, size of CD, CD start position and annotation length. The first source installation package total size 7432883 bytes, wherein 7432882-7432883 two bytes represent an annotation length value of 0, i.e., represent that the annotation content is null. Of course, the comment length value may be represented by a plurality of bytes, and is not limited herein. The specified location of the V1 signature source packet may be a byte location after 7432883.

Taking fig. 4 as an example, the second source installation packet is generated by filling the setting field in the designated position of the V1 signature source packet, where the second source installation packet may fill the setting field with a length of 4 kbytes in the designated position 7432882-7436979, and the specific value of the setting field may be set as required, which is not limited herein.

V2 signature, namely a signature mode of Android, records signature information by inserting an APK signature partition between a data area and a central directory, and can ensure the integrity of original APK data.

V3 signature, a signature mode of Android, adopts the same signature block format of V2, and is different from V2 signature in that the size of an APK signature block must be a multiple of 4096, and information about supported SDK (Software Development Kit ) version and prof-of-rotation structure is added.

Taking fig. 5 as an example, the first source installation package is signed by V2, and the first source installation package may include: the contents of the ZIP entry, the APK signature block (APK Signing Block), the ZIP central directory, and the ZIP central directory end. Wherein, the APK signature block includes: ASB block length, ID-Value key pair, and magic number, where two 8 bytes of 7393280-7393287 and 7397352-7397359 represent the length of an APK signature block (4088 bytes). 7393288-7397351 total 4064 bytes of ID-Value key pairs include: v2 signature magic key-value pairs and padding magic key-value pairs.

Taking fig. 6 as an example, the second source installation packet is generated by filling the setting field in the designated position of the V2 signature source packet, where the second source installation packet may fill the setting field with a length of 4 kbytes in the designated position 7397352-7401447, and the specific value of the setting field may be set as required, which is not limited herein.

In some embodiments, the first source installation package includes a data block and other blocks, the designated locations being located in the other blocks.

In some examples, the first source install package is signed by V1 and the other blocks are the ZIP central directory ends (End of Centry Directory) into which the set fields may be filled.

In some examples, the first source installation package is a V2 signature and the other blocks are APK signature blocks (APK Signing Block), and the set fields may be populated to the APK signature blocks (APK Signing Block).

In other words, the setting field is filled into other blocks, so that the situation of changing the data of the data block of the first source installation package is effectively reduced, and the integrity of the second source installation package is improved.

Step S230, constructing channel package information of the application according to source package information of the second source installation package and channel information of the target channel; the channel package information comprises a downloading address of the channel package and verification information of the channel package, and the channel package is an installation package for writing the channel information in a setting field of the second source installation package.

In this embodiment, the target channel is one or more services capable of providing downloading and updating applications, and different channels correspond to different channel information, that is, different channel information may represent the corresponding channels.

In this embodiment, in a case where the distribution server and the download server are independent of each other, the download address of the channel package may be one of the download servers. In the case where the distribution server and the download server are the same, the download address of the channel package may be one of the distribution servers.

In some embodiments, the download address of the channel package is for the client to download the channel package based on the download request of the user, and the verification information of the channel package is for the client to confirm whether the channel package is successfully downloaded.

In some embodiments, the downloading of channel packages may be based on a content delivery network (Content Delivery Network, CDN) that is a layer of intelligent virtual network formed by placing node servers throughout the network on top of the existing internet, capable of redirecting the user's download requests to the service node closest to the user in real time based on the network traffic and comprehensive information of the connection of each node, load conditions, and distance and response time to the user. The user can obtain the required content nearby, so that the congestion condition of the Internet is solved, the response speed of the user for accessing the website is improved, and the content is transmitted faster and more stably.

In some examples, for the same application, different channels may correspond to the same download address, or may correspond to different download addresses, which is not limited herein.

In this embodiment, after the user terminal downloads all or part of the channel package of the application, the verification data of all or part of the channel package is calculated based on the setting algorithm, or the byte number of all or part of the channel package of the application is confirmed. The verification information of the channel package of the application may include the byte number of the channel package, and if the byte number of the channel package is consistent with the byte number obtained by verification, it may be confirmed that all or part of the downloaded channel package is complete. The verification information of the channel packet may further include verification data such as header verification value and tail verification value of the channel packet, so that after all or part of the application channel packet is downloaded, the user terminal can compare the header verification data and the tail verification value in the channel packet information with the calculated corresponding verification data, and can confirm that all or part of the downloaded channel packet is complete when the comparison result is that the two verification data are identical. Under the condition that the comparison result is that the two verification data are different or inconsistent, the fact that all or part of the downloaded channel package is incomplete can be confirmed. The setting Algorithm is, for example, a cyclic redundancy check (Cyclic Redundancy Check, CRC) Algorithm or a Message-Digest Algorithm 5 (md5), and the like, and is not limited herein.

The number of bytes of the header field corresponding to the header of the channel packet may be set according to needs, for example, the header field is data of header 1K, 5K, 10K or 20K, etc. Similarly, the byte number of the tail field corresponding to the tail of the channel packet may be set according to the requirement, for example, the tail field is data of tail 1K, 5K, 10K or 20K, etc., which is not limited herein.

Taking fig. 4 as an example, channel information of a target channel is filled in 7432882-7436979 of the ZIP central directory end of the second source installation package, a corresponding channel package is obtained, and an MD5 value of a header field of the channel package is calculated. Taking the header field as the header 10K data and the tail field as the tail 10K data as an example, the header check value is the MD5 value of the header 10K data, and the MD5 value of the tail field of the channel packet, namely the CRC value of the tail 10K data, is calculated, and then the MD5 value and the CRC value are used as check information. The user terminal of the user can download the channel package through the download server, the user terminal can calculate the MD5 value of the head 10K data of the downloaded channel package and the CRC value of the tail 10K data of the channel package, and under the condition that the two MD5 values and the two CRC values are the same, the channel package downloaded by the user can be confirmed to be complete, so that the channel package is successfully downloaded by the client.

Step S240, distributing channel package information according to the target channel so as to provide a channel package downloading control associated with the channel package information on a client page corresponding to the target channel.

In this embodiment, the client page is a page displayed by a client for opening a target channel by a user terminal.

In this embodiment, download controls of different applications may be displayed on a client page corresponding to a target channel, and a user may trigger downloading of a channel package of an application by clicking a display area corresponding to the download control of the application or touching some physical buttons on a user terminal to indicate an operation of selecting the application.

In this embodiment, the client page may display, to the user, information such as a channel package waiting to be downloaded in the queue, a download progress bar of the channel package being downloaded, and a downloaded channel package.

In this embodiment, the distribution server may distribute channel package information of the target channel to the application server of the target channel, so that when the user terminal of the user opens a client page corresponding to the target channel, the application server may provide a channel package download control associated with the channel package information on the client page.

< second embodiment >

Fig. 7 shows a flow chart of a channel package distribution method according to a second embodiment. Unlike the first embodiment described above, in this embodiment, in order to improve the security of information transmission and the accuracy of verification, the download address may be set with a corresponding encrypted string, and the channel packet may confirm whether the channel packet is complete by using the number of bytes in its entirety, the verification values corresponding to the data block and other blocks of the channel packet, and so on. As shown in fig. 7, the channel package distribution method of the present embodiment may further include, after step S220, step S221:

step S221, source package information of a second source installation package is obtained, and the source package information is recorded in an information item of an application so as to construct channel package information of the application; the source packet information comprises the byte number of the second source installation packet, a header field of the second source installation packet, a header check value of the header field, a tail field of the second source installation packet and a tail check value of the tail field; the download address of the channel packet comprises an encryption character string corresponding to the channel information, and the verification information of the channel packet comprises the byte number of the channel packet, the head verification value of the channel packet and the tail verification value of the channel packet.

In this embodiment, the number of bytes of the second source installation packet may be the whole number of bytes, for example, fig. 4, the number of bytes of the whole second source installation packet is 7436979, or the number of bytes of a certain block in the second source installation packet, for example, fig. 4, the number of bytes of a data block in the second source installation packet is 7432883, and the number of bytes of other areas in the second source installation packet is 4096. That is, the verification may be performed based on the number of bytes of the entire second source installation packet or the number of bytes of each block of the second source installation packet.

In this embodiment, the byte length of the header field of the second source installation packet may be 5K,10K, 20K, or the like, which is not limited herein. The MD5 value of the header field of the channel packet may be calculated by Message-Digest Algorithm 5 (md5, message-Digest algorism 5). After downloading the corresponding channel package, the user terminal can calculate whether the MD5 value of the header field of the channel package is the same as the MD5 value in the channel package information, so as to confirm whether the downloaded channel package is complete.

In this embodiment, the byte length of the tail field of the second source installation packet may be 5K,10K, 20K, or the like, which is not limited herein.
