Description

应用升级包获取方法及装置Application upgrade package acquisition method and device

技术领域Technical field

本公开涉及网络技术领域，尤其涉及一种应用升级包获取方法及装置。The present disclosure relates to the field of network technologies, and in particular, to an application upgrade package acquiring method and apparatus.

背景技术Background technique

随着网络技术的发展，多种多样的应用如雨后春笋般涌现。为了满足用户越来越多样化或针对性的需求，应用提供商也会积极对应用的版本不断进行更迭，以便进一步完善应用的功能。With the development of network technology, a variety of applications have sprung up. In order to meet the increasingly diverse or targeted needs of users, application providers will also actively change the version of the application to further improve the functionality of the application.

对于终端来说，一个终端上会安装多个应用，于是在将这多个应用升级至最新版本时，会导致较大的流量消耗。为了减小流量消耗，目前的应用升级方法一般采用增量升级方式，在该增量升级过程中一般采用下述方法获取应用升级包：对新旧应用安装包之间直接进行二进制差分，以得到差分升级包，后续终端可以基于该差分升级包进行升级，由于差分升级包的数据量小于整个应用的安装包的数据量，因此，可以实现减小流量消耗的目的。For a terminal, multiple applications are installed on one terminal, and when these applications are upgraded to the latest version, large traffic consumption is caused. In order to reduce the traffic consumption, the current application upgrade method generally adopts an incremental upgrade mode. In the incremental upgrade process, the following application method is generally used to obtain an application upgrade package: binary difference is directly performed between the new and old application installation packages to obtain a difference. The upgrade package can be upgraded based on the differential upgrade package. Since the data volume of the differential upgrade package is smaller than the data volume of the installation package of the entire application, the purpose of reducing the traffic consumption can be achieved.

本公开实施例提供的方法，通过对安装包进行解压，从而可以对解压后的文件根据文件是否能够被进一步分解来进行区别化的差分处理，以得到应用的差分升级包，由于一些可进一步分解的文件占安装包的相当大比重，因此，对解压后的文件进行差分所得到的差分结果相对于不解压而直接进行二进制差分的差分结果，其差分升级包数据量更小，可以进一步减小应用升级所需的流量消耗。The method provided by the embodiment of the present disclosure can perform differential processing on the decompressed file according to whether the file can be further decomposed according to the decompression of the installation package, so as to obtain a differential upgrade package of the application, which may be further decomposed. The file accounts for a considerable proportion of the installation package. Therefore, the difference result obtained by the difference between the decompressed files is directly compared with the binary difference of the non-decompressed, and the difference upgrade packet has a smaller amount of data, which can be further reduced. The traffic consumption required to apply the upgrade.

在一种可能实现方式中，根据所述各个文件的文件类型，对所述至少一个原文件和所述至少一个目标文件进行与所述文件类型相应的差分处理，得到至少一个差分文件包括：In a possible implementation, the at least one original file and the at least one target file are subjected to differential processing corresponding to the file type according to the file type of each file, and obtaining at least one difference file includes:

对于文件名称相同的第一文件和第二文件，如果所述第一文件和所述第二文件为第一类型，则对比所述第一文件和所述第二文件的目录内的文件特征值，生成一个文件记录，所述文件记录用于记录所述第二文件相对于所述第一文件的目录内的文件增减；根据所述文件记录，生成第一差分文件；其中，所述第一文件为原文件，所述第二文件为目标文件。For the first file and the second file having the same file name, if the first file and the second file are of the first type, comparing the file feature values in the directory of the first file and the second file Generating a file record for recording a decrease or decrease of the file in the directory of the second file relative to the first file; generating a first difference file according to the file record; wherein One file is the original file, and the second file is the target file.

对于文件名称相同的第三文件和第四文件，如果所述第一文件和所述第二文件为第二类型，则对所述第三文件和所述第四文件进行二进制差分，生成第二差分文件；其中，所述第三文件为原文件，所述第四文件为目标文件。For the third file and the fourth file having the same file name, if the first file and the second file are of the second type, performing binary difference on the third file and the fourth file to generate a second a differential file; wherein the third file is an original file, and the fourth file is an object file.

结合上述任一种可能实现方式，在一种可能实现方式中，所述第一类型的文件包括后缀为.dex的文件、后缀为.arsc的文件，所述第二类型的文件包括文件夹文件。In combination with any of the foregoing possible implementation manners, in a possible implementation manner, the file of the first type includes a file with a suffix of .dex and a file with a suffix of .arsc, and the second type of file includes a file. Folder file.

上述所有可选技术方案，可以采用任意结合形成本公开的可选实施例，在此不再一一赘述。All of the above optional technical solutions may be combined to form an optional embodiment of the present disclosure, and will not be further described herein.

图2A是根据一示例性实施例示出的应用升级包获取方法的流程图，如图2A所示，应用升级包获取方法用于服务器中，包括以下步骤。FIG. 2A is a flowchart of an application upgrade package obtaining method according to an exemplary embodiment. As shown in FIG. 2A, an application upgrade package obtaining method is used in a server, and includes the following steps.

在步骤201中，解压应用的第一安装包和第二安装包，得到至少一个原文件和至少一个目标文件，所述第一安装包的版本低于所述第二安装包的版本。In step 201, the first installation package and the second installation package of the application are decompressed to obtain at least one original file and at least one target file, and the version of the first installation package is lower than the version of the second installation package.

其中，应用的第一安装包和第二安装包均用于指代应用的全量安装包，也即是，第一安装包内和第二安装包内均包括有对应版本所需的所有安装文件。其中，第二安装包可以为该应用当前最新版本的安装包。The first installation package and the second installation package of the application are used to refer to the full installation package of the application, that is, all the installation files required by the corresponding version are included in the first installation package and the second installation package. . The second installation package may be an installation package of the latest version of the application.

发明人认识到，对于任一种应用来说，其应用的安装包事实上均为一种压缩包，因此，可以通过解压来得到该安装包内的所有安装文件，因此，服务器可以通过解压后的安装文件，来进行升级包的获取过程。The inventor has realized that for any application, the installation package of the application is actually a compressed package, so all the installation files in the installation package can be obtained by decompression, so the server can be decompressed. The installation file to get the upgrade package acquisition process.

在本公开实施例中，应用提供商在应用新版本开发后，可以将该新版本也即是应用的第二安装包上传或发布至服务器。因此，服务器在获取到应用的第二安装包后，可以根据该应用获取该应用的第一安装包，从而对第一安装包和第二安装包分别进行解压，以得到至少一个原文件和至少一个目标文件。其中，至少一个原文件和至少一个目标文件可以分别存储于独立的文件夹中，以便区别。In the embodiment of the present disclosure, after the application version is developed, the application provider may upload or publish the new version, that is, the second installation package of the application, to the server. Therefore, after obtaining the second installation package of the application, the server may obtain the first installation package of the application according to the application, thereby decompressing the first installation package and the second installation package respectively to obtain at least one original file and at least An object file. At least one original file and at least one target file may be separately stored in separate folders for distinction.

对于服务器来说，本公开实施例所提供的应用升级包获取过程可以是由接收到应用的第二安装包后自动触发，也可以是由服务器管理人员通过操作指令触发，服务器可以维护一个应用管理列表，该应用管理列表用于记录当前服务器上已有的应用的版本信息、存储地址等，当接收到任一个应用的第二安装包，则可以根据应用查询该应用管理列表，以获取应用的第一安装包的存储地址，进而从该存储地址获取到该应用的第一安装包，以执行步骤201的解压步骤，而对于通过操作指令触发的过程也可以与上述过程同理，当然，也可以由管理人员直接从服务器的其他位置或是其他接入设备上将该应用的第一安装包复制过来，本公开实施例对此不做具体限定。For the server, the application upgrade package obtaining process provided by the embodiment of the present disclosure may be triggered automatically after receiving the second installation package of the application, or may be triggered by the server management personnel by using an operation instruction, and the server may maintain an application management. The application management list is used to record the version information, the storage address, and the like of the existing application on the current server. When receiving the second installation package of any application, the application management list may be queried according to the application to obtain the application. The storage address of the first installation package, and the first installation package of the application is obtained from the storage address to perform the decompression step of step 201, and the process triggered by the operation instruction may also be the same as the above process, of course, The first installation package of the application may be copied from the other location of the server or other access device by the administrator. The embodiment of the disclosure does not specifically limit this.

当然，服务器在接收到应用的第二安装包后，可以首先对第二安装包进行安全监测，以避免恶意应用的上传，该安全监测可以包括采用杀毒引擎进行检测以及对敏感信息进行检测等过程，本公开实施例对此不做限定。Of course, after receiving the second installation package of the application, the server may first perform security monitoring on the second installation package to avoid uploading of the malicious application, and the security monitoring may include using an antivirus engine for checking. The process of detecting and detecting sensitive information is not limited in this embodiment of the present disclosure.

在步骤202中，确定各个文件的文件类型，所述文件类型用于指示文件是否能够被进一步分解。In step 202, a file type of each file is determined, the file type being used to indicate whether the file can be further broken down.

在该步骤202中所涉及的各个文件是指上述至少一个原文件和至少一个目标文件，对于应用的至少一个原文件和至少一个目标文件来说，由于文件的存在形式不同，有的文件是不可进一步分解文件，例如，classes.dex文件，是作为一个独立文件存在，则该文件不可被进一步分解，有的文件如用于放置资源文件的文件夹等可以被进一步分解，例如res文件夹是一个文件夹，该文件夹的目录内具有多个资源文件如图片等，则该文件属于可被进一步分解。The respective files involved in the step 202 refer to the at least one original file and the at least one target file. For at least one original file and at least one target file of the application, some files are not available due to different forms of the files. Further decomposing the file, for example, the classes.dex file exists as a separate file, the file cannot be further decomposed, and some files, such as folders for placing resource files, can be further decomposed, for example, the res folder is a A folder whose directory has multiple resource files such as pictures, etc., and the file belongs to can be further decomposed.

综上，则可以对于所述至少一个原文件和至少一个目标文件中文件名称相同的文件，判断所述文件是否能够被进一步分解，如果是，则确定所述文件为第一类型，如果否，则确定所述文件为第二类型，从而确定各个文件的文件类型。In summary, it may be determined whether the file can be further decomposed for the file with the same file name in the at least one original file and the at least one target file, and if yes, determine that the file is of the first type, and if not, Then determining that the file is of a second type, thereby determining the file type of each file.

发明人认识到，对于至少一个原文件和至少一个目标文件来说，由于目标文件是更新了的应用所包括的安装文件，因此，该至少一个目标文件和至少一个原文件如果对比来看，具有一定的关系，例如，至少一个目标文件中可以包括以下几类文件：(1)与至少一个原文件中某些原文件的文件名称相同的文件。这种文件，可能是新版本应用中并未对该文件进行更新，也可能是虽然对该文件进行了更新，但是并未进行如删除文件或增加文件等更新，而是在该文件的目录文件内进行了删除或增加等更新。(2)至少一个原文件中没有的文件。这种文件则是新版本应用中所增加的功能等所对应的文件。当然，上述所涉及的原文件和目标文件，均是指通过步骤201的解压得到的同一层级的文件，例如，在一次解压后，得到了文件A、文件B和文件夹C，文件夹C中还包括文件C1、C2和C3，则文件A、文件B和文件夹C属于同一层级的文件，而文件C1、C2和C3则属于下一层级的文件，该层级关系可以以此类推，在此不做赘述。The inventor recognizes that, for at least one original file and at least one object file, since the target file is an installation file included in the updated application, the at least one object file and the at least one original file have, if compared, A certain relationship, for example, at least one object file may include the following types of files: (1) a file having the same file name as some of the original files in at least one of the original files. Such a file may not be updated in the new version of the application, or it may be updated, but the update is not performed, such as deleting files or adding files, but in the directory file of the file. Updates such as deletions or additions have been made. (2) At least one document that is not in the original document. This kind of file is the file corresponding to the added functions in the new version of the application. Of course, the original file and the target file mentioned above refer to the file of the same level obtained by the decompression of step 201. For example, after one decompression, file A, file B and folder C are obtained, and folder C is obtained. Also includes files C1, C2, and C3, where file A, file B, and folder C belong to the same level of files, while files C1, C2, and C3 belong to the next level of files, and the hierarchical relationship can be deduced by analogy. Do not repeat them.

在步骤203中，对于文件名称相同的第一文件和第二文件，如果所述第一文件和所述第二文件为第一类型，则对比所述第一文件和所述第二文件的目录内的文件特征值，生成一个文件记录，所述文件记录用于记录所述第二文件相对于所述第一文件的目录内的文件增减；根据所述文件记录，生成第一差分文件；其中，所述第一文件为原文件，所述第二文件为目标文件。 In step 203, for the first file and the second file having the same file name, if the first file and the second file are of the first type, comparing the directories of the first file and the second file a file feature value, generating a file record, the file record is used to record the second file relative to the file in the directory of the first file increase and decrease; according to the file record, generating a first difference file; The first file is an original file, and the second file is an object file.

对于第一文件和第二文件来说，由于均为可进一步分解的文件，因此，第一文件目录内可以包括至少一个文件，而第二文件目录内也可以包括至少一个文件，此时，为了获知更新的应用对目录内哪个文件进行了更新，可以通过对比文件特征值来进行对比，从而获取目录内删除了哪个文件、增加了哪个文件，根据该删除以及增加，生成一个文件记录，用于记录第二文件相对于所述第一文件的目录内的文件增减。当然，如果该文件中还包括可进一步分解的文件，则可以再基于下一层文件采取与上述类似的方式来进行差分，本公开实施例对此不做具体限定。For the first file and the second file, since the files are further decomposed, at least one file may be included in the first file directory, and at least one file may be included in the second file directory. It is known that the updated application updates the file in the directory, and can compare the file feature values to obtain which file is deleted in the directory, which file is added, and a file record is generated according to the deletion and addition. Recording a second file is increased or decreased relative to a file in the directory of the first file. Of course, if the file further includes a file that can be further decomposed, the difference can be made in a manner similar to the above method based on the next layer of the file, which is not specifically limited in the embodiment of the present disclosure.

需要说明的是，该第一类型的文件可以为文件夹类型的文件，例如，res文件夹和assets文件夹，其中，res文件夹是存放安卓(Android)应用程序中的资源文件夹，该资源可以包括各种图标、图片等。因此，可以通过对比res目录下的所有文件的特征值(例如，md5)，得到哪些是新的图片，哪些图片在新版本中被删除了，从而生成第一差分文件，当然，该第一差分文件也可以是文件夹形式，本公开实施例对此不做限定。assets文件夹类似于res文件夹，也可以生成差分assets文件夹。It should be noted that the first type of file may be a folder type file, for example, a res folder and an assets folder, wherein the res folder is a resource folder in an Android application, the resource. Various icons, pictures, and the like can be included. Therefore, by comparing the feature values of all the files in the res directory (for example, md5), it is obtained which are new pictures and which pictures are deleted in the new version, thereby generating a first difference file, of course, the first difference The file may also be in the form of a folder, which is not limited by the embodiment of the present disclosure. The assets folder is similar to the res folder, and it can also generate a differential assets folder.

例如，参见图2B和图2C，图2B是一个应用的第二安装包解压后所得到的至少一个目标文件的示意图。其中，第一栏为解压后的目标文件，第二栏为目标文件中“mishopWebView_new”文件夹中包括的二级文件，而第三栏为二级文件中res文件夹所包括的三级文件，第四栏则为三级文件中“drawable-xxhdpi-v4”文件夹所包括的四级文件。在进行差分时，当确定“mishopWebView_new”文件夹是一个第一类型的文件时，则可以进一步确定该文件夹内的文件的类型，从图2B上所示可以看出，res文件夹以外的均为第二类型，则进一步确定该res文件夹内的文件的类型，从图2B上所示可以看出，res文件夹内均为第一类型的文件，则进一步确定该“drawable-xxhdpi-v4”内文件的类型，从图2B上所示可以看出，“drawable-xxhdpi-v4”内的文件均为第二类型，则可以对其进行文件特征值的一一对比，确定该第二文件的“drawable-xxhdpi-v4”文件夹相对于第一文件的“drawable-xxhdpi-v4”文件夹内，增加了pay_，可以将该增加图片记录至文件记录，以便与其他增减一同生成整个文件_A夹.pn的g文件记录，再根据该文件记录可以生成第一差分文件，在所生成的第一差分文件中可以包括如图2C所示的“mishopWebView_patch”文件夹内的数据。当然，上述举例仅是一种实现方式的示例，本公开实施例对生成的文件记录以及根据文件记录生成的差分文件的具体文件形式可以不做限定。For example, referring to FIG. 2B and FIG. 2C, FIG. 2B is a schematic diagram of at least one object file obtained after decompressing a second installation package of an application. The first column is the decompressed object file, the second column is the secondary file included in the "mishopWebView_new" folder in the target file, and the third column is the third-level file included in the res folder of the secondary file. The fourth column is the four-level file included in the "drawable-xxhdpi-v4" folder in the third-level file. When the difference is made, when it is determined that the "mishopWebView_new" folder is a file of the first type, the type of the file in the folder can be further determined. As can be seen from FIG. 2B, the outside of the res folder For the second type, the type of the file in the res folder is further determined. As shown in FIG. 2B, the res folder is the first type of file, and the "drawable-xxhdpi-v4" is further determined. "The type of the internal file, as shown in Figure 2B, the files in "drawable-xxhdpi-v4" are all of the second type, then the file eigenvalues can be compared one by one to determine the second file. The "drawable-xxhdpi-v4" folder is added with the pay_ in the "drawable-xxhdpi-v4" folder of the first file, and the added image can be recorded to the file record to generate the entire file together with other additions and subtractions. _A folder.pn g file record, according to the file record can generate a first difference file, in the generated first difference file can include the data in the "mishopWebView_patch" folder as shown in Figure 2COf course, the above examples are merely examples of one implementation, and the embodiments of the present disclosure are The generated file record and the specific file form of the difference file generated based on the file record may not be limited.

在步骤204中，对于文件名称相同的第三文件和第四文件，如果所述第一文件和所述第二文件为第二类型，则对所述第三文件和所述第四文件进行二进制差分，生成第二差分文件；其中，所述第三文件为原文件，所述第四文件为目标文件。In step 204, for the third file and the fourth file having the same file name, if the first file and the second file are of the second type, the third file and the fourth file are binary. Differentially, generating a second difference file; wherein the third file is an original file, and the fourth file is an object file.

对于第三文件和第四文件来说，由于均为无法进一步分解的文件，因此，可以直接采用对文件进行二进制差分的方式，得到文件之间的差别，当然，通过二进制差分，可能得到的结果是该两个文件之间没有改变，说明新版本并未对该部分进行修改，而如果通过二进制差分所得到的差分结果不为0，则说明新版本对该部分进行了一定修改，则可以基于差分结果生成第二差分文件。For the third file and the fourth file, since they are files that cannot be further decomposed, the binary difference between the files can be directly used to obtain the difference between the files. Of course, the results can be obtained by binary difference. There is no change between the two files, indicating that the new version does not modify the part, and if the difference result obtained by the binary difference is not 0, it means that the new version has some modifications to the part, then it can be based on The difference result generates a second difference file.

需要说明的是，该第二类型的文件可以包括后缀有.dex的文件，例如，classes.dex文件，该第二类型的文件还可以是后缀为.rasc的文件，例如，resources.arsc文件。其中，classes.dex是安卓(Android)***中可以在Dalvik虚拟机上直接运行的文件格式，无法再次分解，因此，把原文件和目标文件中的classes.dex文件作二进制对比差分，得到classes.patch的差分文件。而resources.arsc文件是用来描述具有ID值的资源配置信息，其内容相当于是一个资源索引表，也无法再次分解，因此可以采用与classes.dex文件一样的二进制差分处理，生成resources.patch的差分文件。It should be noted that the second type of file may include a file suffixed with .dex, for example, a classes.dex file, and the second type of file may also be a file with a suffix of .rasc, for example, a resources.arsc file. Among them, classes.dex is a file format that can be run directly on the Dalvik virtual machine in the Android system. It cannot be decomposed again. Therefore, the classes.dex files in the original file and the target file are binary-differentiated and differentiated to obtain classes. Patch differential file. The resources.arsc file is used to describe the resource configuration information with the ID value. The content is equivalent to a resource index table and cannot be decomposed again. Therefore, the same binary difference processing as the classes.dex file can be used to generate the resources.patch. Differential file.

上述步骤203至步骤204为根据所述各个文件的文件类型，对所述至少一个原文件和所述至少一个目标文件进行与所述文件类型相应的差分处理，得到至少一个差分文件。当然，对于上述(2)中所涉及的至少一个原文件中没有的文件，则可以通过文件名称的对比确定，服务器可以将这些文件名称存在于至少一个目标文件中，但不存在于至少一个原文件中的文件，获取为第三差分文件。Step 203 to step 204 are performed by performing differential processing corresponding to the file type on the at least one original file and the at least one target file according to the file type of each file, to obtain at least one difference file. Of course, for the files that are not included in the at least one original file involved in (2) above, the file name may be compared by the server name, and the server may have the file names in at least one target file, but not exist in at least one original file. The file in the file is obtained as the third differential file.

在步骤205中，将所述至少一个差分文件进行压缩，得到所述应用的差分升级包。In step 205, the at least one difference file is compressed to obtain a differential upgrade package of the application.

通过将上述步骤所得到的至少一个差分文件合并后进行压缩，以得到应用的差分升级包。此时，服务器可以得到一个较小的差分升级包。当然，如果服务器上存储有一个应用的多个版本，还可以针对每个版本以及这个最新版本，生成至少一个差分升级包，每个差分升级包对应于一个原版本和一个目标版本，每个差分升级包的具体内容会根据版本之间的数据变化而不同。The at least one difference file obtained by the above steps is combined and compressed to obtain an applied differential upgrade package. At this point, the server can get a smaller differential upgrade package. Of course, if there are multiple versions of an application stored on the server, at least one differential upgrade package can be generated for each version and the latest version, and each differential upgrade package corresponds to one original version and one target version. The specific content of each differential upgrade package will vary depending on the data between versions.

针对上述至少一个差分升级包，终端在需要进行版本升级时，可以在升级请求中携带终端已有的应用版本信息，由服务器根据接收到的应用版本信息以及最新版本，获取对应的差分升级包，并将改获取到的差分升级包发送至终端，使得终端能够在已有的应用版本的基础上，将已有应用的安装文件和该差分升级包合并，以实现应用的版本升级。当然，根据差分升级包内具体内容的不同，该合并可以是指在终端已有应用的安装文件中增加、减少某些数据，本公开实施例对此不做具体限定。For the at least one differential upgrade package, when the terminal needs to be upgraded, the terminal may carry the application version information of the terminal in the upgrade request, and the server obtains the corresponding differential upgrade package according to the received application version information and the latest version. And sending the obtained differential upgrade package to the terminal, so that the terminal can merge the installation file of the existing application and the differential upgrade package on the basis of the existing application version, so as to implement the version upgrade of the application. Of course, according to the specific content in the differential upgrade package, the merging may refer to adding or reducing some data in the installation file of the application already in the terminal, which is not specifically limited in this embodiment of the present disclosure.

本公开实施例提供的方法，通过对安装包进行解压，从而可以对解压后的文件根据文件是否能够被进一步分解来进行区别化的差分处理，以得到应用的差分升级包，由于一些可进一步分解的文件占安装包的相当大比重，因此，对解压后的文件进行差分所得到的差分结果相对于不解压而直接进行二进制差分的差分结果，其差分升级包数据量更小，可以进一步减小应用升级所需的流量消耗。并且，通过上述解压后根据文件是否能够被进一步分解来进行区别化的差分处理，使得差分处理所得到的差分结果更加稳定，不容易出现数据错误。进一步地，这种差分升级包的获取方式，也更加适用于一些本身数据量较小的应用。The method provided by the embodiment of the present disclosure can perform differential processing on the decompressed file according to whether the file can be further decomposed according to the decompression of the installation package, so as to obtain a differential upgrade package of the application, which may be further decomposed. The file accounts for a considerable proportion of the installation package. Therefore, the difference result obtained by the difference between the decompressed files is directly compared with the binary difference of the non-decompressed, and the difference upgrade packet has a smaller amount of data, which can be further reduced. The traffic consumption required to apply the upgrade. Further, by performing the above-described decompression and differential processing based on whether or not the file can be further decomposed, the difference result obtained by the differential processing is more stable, and data errors are less likely to occur. Further, the acquisition method of the differential upgrade package is also more suitable for some applications with a small amount of data.
