It should be noted that the cloud service application upgrade method provided in the embodiment of the present application is generally executed by the client 101, and accordingly, the cloud service application upgrade apparatus is generally disposed in the client 101. The details of implementation of the technical solution of the embodiments of the present application are set forth in the following.
Referring to fig. 2, fig. 2 is a flowchart of a cloud service application upgrade method according to an exemplary embodiment of the present application, an execution subject of the cloud service application upgrade method in the present embodiment is a client 101, and the cloud service application upgrade method shown in fig. 2 may include the following steps S210 to S260, which are described in detail as follows.
In step S210, an upgrade request for upgrading the cloud service application is sent to the cloud server, where the upgrade request includes an upgrade version number of the cloud service application.
In an embodiment, the cloud service application is used as application software for implementing the cloud service at the client, and when a user needs to upgrade the cloud service application at the client, an upgrade request for upgrading the cloud service application may be sent to the cloud server, where the upgrade request at least carries an upgrade version number that needs to be upgraded for the cloud service application, and of course, the upgrade request may also include unique identification information of the client.
In step S220, response information fed back by the cloud server for the upgrade request is received, where the response information includes identification information of the plurality of fragment files and first file check values respectively checked on the plurality of fragment files determined by performing message digest calculation according to the contents of the plurality of fragment files, and the plurality of fragment files are generated when the cloud server performs fragment processing on the installation software package corresponding to the upgrade version number.
In one embodiment, after receiving an upgrade request from a client, a server feeds back response information for the upgrade request to the client, where the response information includes a plurality of fragment files generated according to installation software package information corresponding to an upgrade version number carried in the upgrade request. Because the data volume corresponding to a single installation software package is large, in order to ensure the smooth transmission of data and the safety of transmission, the cloud server can perform fragmentation processing on the installation software package corresponding to the upgrade version number to generate a plurality of corresponding fragment files, and calculate the contents of the plurality of fragment files through a message digest algorithm respectively to obtain a calculation result, wherein the calculation result is used as a first file check value for performing integrity check on the contents of the plurality of fragment files. It can be understood that the response information further includes identification information of each fragmented file, where the identification information is unique identification information for identifying each fragmented file, and is used by the cloud server and the client to identify the fragmented file.
It should be noted that, for the fragmented files obtained by splitting the installation software package, a single fragmented file cannot be opened, and when the installation software package is subjected to the fragmentation operation, the installation software package may be split specifically by taking a file as a unit, the fragmented files obtained by splitting may include one or more files, and the data volume of each fragmented file is generally within a predetermined data volume size range.
When the contents of the plurality of fragmented files are calculated through a message digest algorithm, a MD5 message digest algorithm or a SHA secure hash algorithm may be specifically adopted to calculate to obtain a corresponding first file check value, so that the integrity of the contents of the installed software package is verified based on the first file check value, and the data integrity of the installed software package is further ensured.
In step S230, a download request for downloading the plurality of segment files is sent to the cloud server based on the identification information of the plurality of segment files.
In an embodiment, after receiving the response information from the cloud server, the client may generate a download request for downloading the plurality of fragmented files according to the identification information of the plurality of fragmented files included in the response information, and send the download request to the cloud server. It will be appreciated that the download request also includes identification information for each fragmented file.
In step S240, a plurality of fragmented files fed back by the cloud server for the download request are received.
In one embodiment, the cloud server feeds back a plurality of corresponding fragmented files to the client according to identification information of the fragmented files included in the download request when receiving the download request from the client, and the client receives the plurality of fragmented files from the cloud server.
In step S250, message digest calculation is performed according to the received contents of the plurality of fragmented files, and first calculated check values corresponding to the plurality of fragmented files are determined.
In an embodiment, the client performs calculation according to the content contained in each received fragmented file by using a message digest algorithm to obtain the first calculated check value corresponding to each fragmented file, that is, the first calculated check value of each fragmented file is generated according to the content contained in each fragmented file.
In step S260, if it is detected that the first calculated check values corresponding to the plurality of fragmented files are consistent with the first file check values corresponding to the plurality of fragmented files, the cloud service application is upgraded according to the plurality of fragmented files.
In one embodiment, after obtaining the first calculated check value corresponding to each fragmented file, the client compares the first calculated check values corresponding to the fragmented files with the first file check values corresponding to the fragmented files to determine whether the first calculated check values and the first file check values are consistent. If the first calculation check value corresponding to each fragment file is detected to be consistent with the first file check value corresponding to the fragment file, it is indicated that each fragment file corresponding to the installation software package of the cloud service application received from the cloud server is complete, in other words, the content of each fragment file is not tampered or the data is not lost in the transmission process, and the client can upgrade the cloud service application according to the plurality of fragment files; otherwise, it is indicated that the fragment file corresponding to the installation software package of the cloud service application received from the cloud server is not complete, and at this time, the client may stop upgrading the cloud service application according to the plurality of fragment files.
As can be seen from the above, by splitting the installation software package into a plurality of fragment files for transmission, when the installation software package is large, the client can also download the installation software package from the cloud server smoothly, so as to reduce the influence of network fluctuation on the upgrade, and in addition, by comparing the first calculation check value corresponding to the plurality of fragment files corresponding to the received cloud service application installation software package with the first file check value corresponding to the plurality of fragment files, if it is detected that the first calculation check value corresponding to the plurality of fragment files is identical to the first file check value corresponding to the plurality of fragment files, the cloud service application is upgraded according to the plurality of fragment files, so as to avoid performing message digest calculation directly according to the whole upgrade installation package while ensuring the data integrity of the upgrade installation package, reduce the complexity of calculation, thereby effectively reducing the data calculation amount during the data integrity check, therefore, the occupation of system resources is reduced, the upgrading time of the cloud service application is shortened, and the upgrading efficiency of the cloud service application is improved.
In an embodiment, the response information fed back by the cloud server may further include a second file check value obtained by the cloud server performing message digest calculation according to the first file check values corresponding to the plurality of fragmented files, and the cloud service application upgrade method in this embodiment further includes: performing message digest calculation according to first calculation check values corresponding to the plurality of fragmented files, and determining a second calculation check value; step S260 in this embodiment may specifically include: and if the first calculation check values corresponding to the plurality of fragment files are consistent with the first file check values corresponding to the plurality of fragment files and the second calculation check values are consistent with the second file check values, upgrading the cloud service application according to the plurality of fragment files.
In this embodiment, after determining that the first file check values corresponding to the plurality of fragmented files are obtained, the cloud server may further use the first file check values corresponding to the plurality of fragmented files as calculation contents, perform message digest calculation on the calculation contents through a message digest algorithm to obtain a calculation result, where the calculation result may be used as a second file check value for further checking the integrity of the contents of the installed software package, and the cloud server adds the second file check value to the response information.
After determining the first calculation check values corresponding to the plurality of fragmented files, the client may further use the first calculation check values corresponding to the plurality of fragmented files as calculation contents, and perform message digest calculation on the calculation contents through a message digest algorithm to obtain a calculation result, which may be used as a second calculation check value for checking the received fragmented files.
When the client detects that the first calculation check values corresponding to the plurality of fragment files are consistent with the first file check values corresponding to the plurality of fragment files, the client can also compare the second calculation check value obtained through calculation with the second file check value contained in the response information, if the second calculation check value obtained through calculation is also consistent with the second file check value contained in the response information, it is indicated that each fragment file corresponding to the installation software package of the cloud service application received from the cloud server is complete, and the cloud service application can be upgraded according to the plurality of fragment files.
In the technical solution of this embodiment, by comparing the calculated second calculated check value with the second file check value included in the response information, the data integrity of the installed software package acquired in the server can be further ensured, and the accuracy of performing data integrity check is improved.
In an embodiment, the response information fed back by the cloud server may further include fragment sequence information corresponding to the plurality of fragment files obtained when the cloud server performs fragment processing on the upgrade software package corresponding to the upgrade version number, and the step of determining the second calculation check value may specifically include: and performing message digest calculation based on the first calculation check values corresponding to the plurality of fragmented files and the fragmentation sequence information of the plurality of fragmented files, and determining a second calculation check value.
In this embodiment, when the fragmentation sequence information corresponding to the multiple fragmentation files is fragmentation processing performed on the upgrade software package corresponding to the upgrade version number by the cloud server, the fragmentation sequence information is identification information used for identifying a fragmentation sequence corresponding to the multiple fragmentation files, specifically, the fragmentation sequence information may be a character string identifying the sequence information, for example, the fragmentation sequence information of a first fragmentation file obtained by fragmentation may be "000000001", the fragmentation sequence information of a second fragmentation file may be "000000010", and so on, which is not limited thereto.
The cloud server can also take the first file check values corresponding to the fragmented files and the fragmented sequence information of the fragmented files as calculation contents, perform message digest calculation on the calculation contents through a message digest algorithm to obtain calculation results, and the calculation results can be taken as second file check values for further checking the content integrity of the installed software package. After determining the first calculation check values corresponding to the plurality of fragmented files, the client may further use the first calculation check values corresponding to the plurality of fragmented files and the fragment sequence information of the plurality of fragmented files as calculation contents, and perform message digest calculation on the calculation contents through a message digest algorithm to obtain a calculation result, which may be used as a second calculation check value for checking the received fragmented files.
Referring to fig. 3, fig. 3 is a flowchart of a cloud service application upgrade method according to an exemplary embodiment of the present application, in which in this embodiment, message digest calculation is performed based on first calculation check values corresponding to a plurality of fragmented files and fragmentation sequence information of the plurality of fragmented files, and the step of determining the second calculation check value may specifically include steps S310 to S330, which are described in detail below.
In step S310, content attribute information corresponding to each fragmented file is generated according to the first computed check value corresponding to each fragmented file and the fragmentation sequence information corresponding to each fragmented file.
In step S320, the content attribute information of each fragmented file is spliced based on the fragmentation sequence information corresponding to each fragmented file, so as to obtain spliced information.
In step S330, a message digest calculation is performed based on the concatenated information, and a second calculated check value is determined.
When the client performs message digest calculation based on the first calculation check value corresponding to the plurality of fragmented files and the fragmentation sequence information of the plurality of fragmented files to determine the second calculation check value, content attribute information corresponding to each fragmented file may be generated according to the first calculation check value corresponding to each fragmented file and the fragmentation sequence information corresponding to each fragmented file, for example, when the first calculation check value corresponding to the fragmented file is "ABC 11100 BNQ" and the fragmentation sequence information corresponding to the fragmented file is "000000001", the content attribute information corresponding to the fragmented file may be "ABC 11100BNQ 000000001". The client side carries out splicing processing on the content attribute information of each fragment file based on the fragment sequence information corresponding to each fragment file to obtain spliced information, and if the content attribute information of each fragment file is A1 or A2 … An, the spliced information is (A1, A2, … or An); and finally, performing message digest calculation based on the spliced information, and determining a second calculation check value.
It can be understood that the manner in which the client performs the message digest calculation to determine the second calculated check value based on the first calculated check values corresponding to the plurality of fragmented files and the fragmentation sequence information of the plurality of fragmented files is consistent with the manner in which the cloud server performs the message digest calculation to determine the second file check value based on the first file check values corresponding to the plurality of fragmented files and the fragmentation sequence information of the plurality of fragmented files.
In the technical scheme of the embodiment, the integrity of the fragmented files is checked based on the content of the fragmented files and the fragmentation sequence information of the fragmented files, so that the complexity of message digest calculation can be further improved, the situation that a lawbreaker intercepts the fragmented files of the installation software package and tampers the content of the installation software package can be effectively detected, and the safety of data transmission is improved.
Referring to fig. 4, fig. 4 is a specific flowchart of step S230 of a cloud service application upgrading method according to an exemplary embodiment of the present application. In this embodiment, when the response information fed back by the cloud server includes fragment sequence information corresponding to a plurality of fragment files obtained by fragment processing of the upgrade software package corresponding to the upgrade version number by the cloud server, step S230 may specifically include steps S410 to S430, which are described in detail below.
Step S410, determining a downloading order of the plurality of fragmented files based on the fragmentation order information of the plurality of fragmented files.
When downloading each fragment file from the cloud server, the client may determine a downloading order of the plurality of fragment files based on the fragment order information of the plurality of fragment files. Specifically, the fragment sequence information of the plurality of fragment files may be directly used as the download sequence of the plurality of fragment files, for example, a first fragment file obtained when the installation software package is subjected to fragment processing may be used as a first fragment file to be downloaded according to the fragment sequence information, and so on, thereby determining the download sequence of the plurality of fragment files based on the fragment sequence information of the plurality of fragment files.
Step S420, selecting the segment files to be downloaded based on the downloading order, and generating a downloading request according to the identification information corresponding to the selected segment files.
After the downloading sequence of the plurality of fragmented files is determined, the client can select the fragmented files to be downloaded based on the downloading sequence, specifically, the downloading request can be generated according to the identification information corresponding to the selected fragmented files, so that the fragmentation sequence of the plurality of fragmented files can be conveniently given, and the fragmented files can be downloaded from the cloud server.
Step S430, sending a download request to the cloud server.
The client sends the generated downloading request to the cloud server so as to conveniently download the corresponding fragment file from the cloud server.
In the technical scheme of the embodiment shown in fig. 4, the downloading order of the multiple fragmented files is determined based on the fragmented sequence information of the multiple fragmented files, the fragmented files are downloaded one by one from the cloud server according to the downloading order of the multiple fragmented files, and the downloading of the remaining fragmented files from the cloud server can be stopped when a certain received fragmented file is tampered or data is lost, so that unnecessary data processing can be reduced, the occupation of client system resources is reduced, and the utilization rate of client system resources is improved.
Optionally, referring to fig. 5, fig. 5 is a flowchart of a cloud service application upgrading method according to an exemplary embodiment of the present application, where the cloud service application upgrading method in this embodiment may further include step S510 to step S520, which is described in detail as follows.
In step S510, if the first calculated check value calculated according to the content of the received fragmented file is not consistent with the first file check value corresponding to the received fragmented file, the generation of the download request to the cloud server is stopped, and a failure notification of the failure in downloading the upgrade software package is generated.
The client calculates to obtain a first calculation check value according to the content of the received fragmented file, and compares the first calculation check value obtained by calculation with a first file check value corresponding to the received fragmented file. If the calculated first calculation check value is inconsistent with the first file check value corresponding to the received fragment file, it indicates that the content of the received fragment file is tampered or the received fragment file has data loss, and the client stops generating a download request to the cloud server and becomes a failure request for failing to download the upgrade software package.
Step S520, sending a failure notification to the cloud server.
The client sends the failure notice to the cloud server so that the cloud server can conveniently and again send the upgrading software package, and normal upgrading is guaranteed.
