The execution subject of the cloud service application upgrade method in this embodiment is the client 101, as shown in FIG. The service application upgrade method may include the following steps S210 to S260, which are described in detail as follows.

在步骤S210中，发送对云业务应用进行升级的升级请求至云端服务器，升级请求包括云业务应用的升级版本号。In step S210, an upgrade request for upgrading the cloud service application is sent to the cloud server, and the upgrade request includes the upgrade version number of the cloud service application.

在一个实施例中，云业务应用作为客户端用以实现云业务的应用软件，在用户需要对客户端的云业务应用进行升级时，可以向云端服务器发送对云业务应用进行升级的升级请求，该升级请求中至少携带有需要对云业务应用进行升级的升级版本号，当然，升级请求中还可以包括客户端的唯一标识信息。In one embodiment, the cloud service application is used as the client application software to realize the cloud service. When the user needs to upgrade the cloud service application of the client, the upgrade request for upgrading the cloud service application can be sent to the cloud server.

Multiple fragmented files. Due to the large amount of data corresponding to a single installation software package, in order to ensure the smooth transmission of data and the security of transmission, the cloud server can perform fragmentation processing on the installation software package corresponding to the upgraded version number to generate corresponding multiple fragment files , And calculate the content of the multiple fragment files respectively through the message digest algorithm to obtain the calculation result, and the calculation result is used as the first file check value for performing integrity verification on the content of the multiple fragment files. It is understandable that the response information also includes identification information of each fragmented file, and the identification information is unique identification information for identifying each fragmented file, and is used for the cloud server and the client to identify the fragmented file.

需要指出的是，对安装软件包进行拆分所得到的分片文件，单个分片文件是无法打开的，对安装软件包进行分片操作时，具体可以以文件为单位来对安装软件包进行拆分，拆分所得到的分片文件可以包括一个或多个文件，各个分片文件的数据量大小一般处于预定数据量大小范围内。It should be pointed out that, for the fragmented file obtained by splitting the installation software package, a single fragmented file cannot be opened. When the installation software package is fragmented, the installation software package can be performed in units of files. Splitting. The split file obtained by splitting may include one or more files, and the data size of each split file is generally within a predetermined data size range.

在对多个分片文件的内容通过消息摘要算法进行计算时，具体可以采用MD5消息摘要算法或SHA安全散列算法进行计算得到对应的第一文件校验值，以便于基于该第一文件校验值对安装软件包的内容完整性进行验证，进而保证安装软件包的数据完整性。When calculating the content of multiple fragmented files through the message digest algorithm, the MD5 message digest algorithm or the SHA secure hash algorithm can be used to calculate the corresponding first file check value, so as to facilitate the calibration based on the first file. The verification value verifies the content integrity of the installation software package, thereby ensuring the data integrity of the installation software package.

在步骤S230中，基于多个分片文件的标识信息，发送下载多个分片文件的下载请求至云端服务器。In step S230, based on the identification information of the multiple fragment files, a download request for downloading the multiple fragment files is sent to the cloud server.

在一个实施例中，客户端在接收到来自云端服务器的响应信息后，可以根据该响应信息中包含的多个分片文件的标识信息来生成对多个分片文件进行下载的下载请求，并将该下载请求发送至云端服务器。可以理解的是，下载请求还包括各个分片文件的标识信息。In one embodiment, after the client receives the response information from the cloud server, it can generate a download request for downloading the multiple fragment files according to the identification information of the multiple fragment files contained in the response information, and Send the download request to the cloud server.

在步骤S250中，根据接收的多个分片文件的内容分别进行消息摘要计算，确定多个分片文件对应的第一计算校验值。In step S250, a message digest calculation is performed respectively according to the content of the received multiple fragment files, and the first calculated check value corresponding to the multiple fragment files is determined.

在一个实施例中，客户端根据接收的各个分片文件所包含的内容通过消息摘要算法进行计算，得到各个分片文件对应的第一计算校验值，即根据每一个分片文件所包含的内容，生成该分片文件的第一计算校验值。In one embodiment, the client calculates the first calculated check value corresponding to each fragment file according to the content contained in each fragment file received by the message digest algorithm, that is, according to the content contained in each fragment file Content, the first calculated check value of the fragment file is generated.

在步骤S260中，若检测到多个分片文件对应的第一计算校验值与多个分片文件对应的第一文件校验值均一致，则根据多个分片文件对云业务应用进行升级。In step S260, if it is detected that the first calculated check value corresponding to the multiple fragment files is consistent with the first file check value corresponding to the multiple fragment files, the cloud service application is performed according to the multiple fragment files. upgrade.

在一个实施例中，在得到各个分片文件对应的第一计算校验值，客户端将多个分片文件对应的第一计算校验值与多个分片文件对应的第一文件校验值进行比对，以确定两者是否一致。如果检测到每个分片文件对应的第一计算校验值与该分片文件对应的第一文件校验值均一致时，说明从云端服务器所接收到的云业务应用的安装软件包所对应的各个分片文件都是完整的，换而言之，各个分片文件在传输过程中，内容未被篡改或数据未丢失，则客户端可以根据多个分片文件对所述云业务应用进行升级；否则，则说明从云端服务器所接收到的云业务应用的安装软件包所对应的分片文件不是完整的，此时，客户端可以停止根据多个分片文件对云业务应用进行升级。In one embodiment, after obtaining the first calculated check value corresponding to each fragment file, the client verifies the first calculated check value corresponding to the plurality of fragment files with the first file corresponding to the plurality of fragment files. The values are compared to determine whether the two are consistent. If it is detected that the first calculated check value corresponding to each fragment file is consistent with the first file check value corresponding to the fragment file, it indicates that the installation software package of the cloud business application received from the cloud server corresponds to Each of the fragmented files is complete. In other words, the content of each fragmented file has not been tampered with or the data has not been lost during the transmission process, and the client can perform operations on the cloud service application according to multiple fragmented files. Upgrade; otherwise, it means that the fragment file corresponding to the installation software package of the cloud service application received from the cloud server is not complete. At this time, the client can stop upgrading the cloud service application based on multiple fragment files.

以上可以看出，通过将安装软件包拆分成多个分片文件来进行传输，在安装软件包较大时，也能使得客户端顺利从云端服务器下载安装软件包，降低了网络波动对升级造成的影响，此外，通过将接收的云业务应用安装软件包对应的多个分片文件对应的第一计算校验值与多个分片文件对应的第一文件校验值，若检测到多个分片文件对应的第一计算校验值与多个分片文件对应的第一文件校验值均一致，则根据多个分片文件对云业务应用进行升级，在保证可以实现对升级安装包的数据完整性的同时，避免根据整个升级安装包直接进行消息摘要计算，降低计算的复杂度，从而可以有效减少对数据完整性校验时的数据计算量，进而减少了***资源的占用，同时还减少了云业务应用的升级时间，提高了云业务应用的升级效率。It can be seen from the above that by splitting the installation software package into multiple fragmented files for transmission, when the installation software package is large, it can also enable the client to download the installation software package from the cloud server smoothly, reducing network fluctuations and upgrading In addition, the first calculated check value corresponding to the multiple fragment files corresponding to the received cloud service application installation software package is combined with the first file check value corresponding to the multiple fragment files. If the first calculated check value corresponding to one fragmented file is consistent with the first file check value corresponding to multiple fragmented files, then the cloud service application is upgraded according to the multiple fragmented files to ensure that the upgrade installation can be realized At the same time as the data integrity of the package, it avoids directly calculating the message digest according to the entire upgrade installation package, reducing the complexity of the calculation, which can effectively reduce the amount of data calculation during data integrity verification, thereby reducing the occupation of system resources. At the same time, the upgrade time of cloud business applications is reduced, and the upgrade efficiency of cloud business applications is improved.
