本文涉及但不限于通信领域，尤其涉及一种差分升级包的处理方法及装置，升级方法、系统及装置。This document relates to but not limited to the field of communications, and in particular, to a method and device for processing a differential upgrade package, and an upgrade method, system and device.
背景技术Background technique
移动终端的FOTA(Firmware Over-The-Air，空中下载软件升级)技术是现在移动终端中使用非常频繁的技术，对于系统版本维护起着重要作用。假设存在版本V1，V2，目前已发布V1-V2的差分升级包，现在新出了V3版本，则用户要升级到V3的方法有：方式1是通过V1-V2、V2-V3升级，称为阶梯升级，方式2是通过V1-V3、V2-V3升级，称为跨版本升级。目前的技术中，随着新版本的增加，方式1在版本发布与测试上控制都非常简单，每个新版本发布只需要测试前一个版本到新版本功能正常即可，但是对于用户而言，如果V1要升级到V3则需要先升级到V2，严重影响用户的体验；方式2对于用户体验有明显改善，但是如果每个新版本都要制作所有旧版本的跨版本升级包，无论是升级包制作还是升级包上传服务器以及升级包测试都是不小的工作量，特别是升级包增多后，由于是人为操作，很容易出现问题。The FOTA (Firmware Over-The-Air) technology of mobile terminals is a very frequently used technology in mobile terminals, and plays an important role in system version maintenance. Assume that there are versions V1 and V2. The V1-V2 differential upgrade package has been released. Now that the V3 version is new, the method for users to upgrade to V3 is as follows: Mode 1 is upgraded through V1-V2 and V2-V3. Step upgrade, mode 2 is upgrade through V1-V3, V2-V3, called cross-version upgrade. In the current technology, with the increase of the new version, the mode 1 is very simple to control on the release and test. Each new version only needs to test the previous version to the new version, but for the user, If V1 is to be upgraded to V3, you need to upgrade to V2 first, which seriously affects the user experience. Mode 2 has a significant improvement on the user experience, but if each new version has to make all the old version of the cross-version upgrade package, whether it is an upgrade package Production or upgrade package upload server and upgrade package test are not small workload, especially after the increase of upgrade package, because it is human operation, it is easy to have problems.
在用户体验至上的时代，方式2是所有厂商都应该选择的方式，为了解决方式2即跨版本升级带来的版本维护问题，在相关技术中，也提出过一些解决办法，在相关技术中，主要提出了两种解决跨版本升级维护问题的方案：方案一，将所有的系统版本放到服务器上，在终端请求时，生成对应的差分升级包然后下发给终端；方案二，服务器上的差分升级包打包到一起下发给终端，终端根据打包后的所有差分包，逐个进行升级，最后升级到最新版本。In the era of user experience first, Mode 2 is a way that all vendors should choose. In order to solve the problem of version 2 maintenance caused by cross-version upgrade, some solutions have been proposed in related technologies. In related technologies, Two schemes for solving the problem of cross-version upgrade maintenance are proposed: scheme one, all system versions are put on the server, and when the terminal requests, the corresponding differential upgrade package is generated and then sent to the terminal; scheme 2, on the server The differential upgrade packages are packaged and delivered to the terminal. The terminal upgrades one by one according to all the packaged packets, and finally upgrades to the latest version.
尽管上述两种方案都能达到简化跨版本升级中的版本维护的工作，但是也存在相应的问题，方案一，由于要把所有的版本都放到服务器上，就会导致服务器需要很大的容量来保存，随着版本的增多，所需容量也会越来越大；方案二，可以减少对服务器容量的需求，但是由于其直接将每个版本的差分升级包打包到一起，可能存在过多的冗余信息，随着版本的增多，由于需要 对差分升级包逐个升级，对于终端的处理要求也会增高。Although both of these solutions can simplify the maintenance of version maintenance in a cross-version upgrade, there are corresponding problems. In the first solution, since all versions are placed on the server, the server needs a large capacity. To save, as the version increases, the required capacity will be larger and larger; Option 2, can reduce the demand for server capacity, but because it directly packs each version of the differential upgrade package, there may be too much Redundant information, as the version increases, due to the need The differential upgrade package is upgraded one by one, and the processing requirements for the terminal are also increased.
针对在相关技术中的跨版本升级中升级包制作和维护工作量大的问题，目前尚未提出有效的解决方案。In view of the large workload of the upgrade package creation and maintenance in the cross-version upgrade in the related art, an effective solution has not been proposed yet.

在本实施例中提供了一种差分升级包的处理方法，图1是根据本发明实施例的差分升级包的处理方法的流程图，如图1所示，该流程包括如下步骤S102～S104：In this embodiment, a method for processing a differential upgrade package is provided. FIG. 1 is a flowchart of a method for processing a differential upgrade package according to an embodiment of the present invention. As shown in FIG. 1 , the process includes the following steps S102 to S104:

步骤S104，将所述指定软件的所述第一版本到所述第三版本的第三差分升级包下发给所述客户端，其中，所述第三差分升级包通过第一差分升级包和预先存储的第二差分升级包生成，所述第一差分升级包为所述指定软件的第二版本到所述第三版本的差分升级包，所述第二差分升级包为所述指定软件的所述第一版本到所述第二版本的差分升级包，其中，所述第三版本高于所述第二版本，所述第二版本高于所述第一版本。Step S104: The third differential upgrade package of the first version to the third version of the specified software is sent to the client, where the third differential upgrade package passes the first differential upgrade package and Pre-stored second differential upgrade package generated, the first differential upgrade package is a differential upgrade package of the second version of the specified software to the third version, and the second differential upgrade package is the designated software The differential upgrade package of the first version to the second version, wherein the third version is higher than the second version, and the second version is higher than the first version.
步骤S102～S104可以但不限于由服务器执行。Steps S102 to S104 may be, but are not limited to, being executed by a server.
通过上述步骤，采用在客户端需要将指定软件从第一版本升级至第三版本的情况下，通过指定软件的第二版本到第三版本的第一差分升级包，和预先存储的指定软件的第一版本到第二版本的第二差分升级包，来生成指定软件从第一版本升级至第三版本的第三差分升级包，然后直接将第三差分升级包下发给客户端的技术方案，解决了相关技术中升级包制作和维护工作量大的问题，达到了减少了升级包制作和维护的工作量的目的，提高了版本升级的效率，降低了维护的成本。 Through the above steps, in the case where the client needs to upgrade the specified software from the first version to the third version, by specifying the first differential upgrade package of the second version to the third version of the software, and the pre-stored designated software. The second differential upgrade package of the first version to the second version is used to generate a third differential upgrade package in which the specified software is upgraded from the first version to the third version, and then the third differential upgrade package is directly delivered to the client. The invention solves the problem that the workload of the upgrade package production and maintenance in the related art is large, and achieves the purpose of reducing the workload of the upgrade package production and maintenance, improves the efficiency of the version upgrade, and reduces the maintenance cost.
需要说明的是，上述第三差分升级包的生成过程可以是在服务器上完成的，在生成之前，需要将上述第一差分升级包上传到服务器上，当服务器接收到该第一差分升级包时，可以触发生成上述第三差分升级包的流程。It should be noted that, the generating process of the foregoing third differential upgrade package may be performed on the server, and before the generating, the first differential upgrade package needs to be uploaded to the server, when the server receives the first differential upgrade package. , the process of generating the third differential upgrade package described above can be triggered.
可选地，上述方法还包括：生成所述第三差分升级包后，删除上述第二差分升级包。Optionally, the method further includes: deleting the second differential upgrade package after the third differential upgrade package is generated.
举个例子：第一版本为版本1，第二版本为版本2，第三版本为版本4；客户端需要将版本1升级至版本4，而服务器上存储有版本1升级至版本2的差分升级包(相当于上述的第二差分升级包)，当服务器接收到版本2到版本4的差分升级包(相当于上述的第一差分升级包)时，触发生成版本1到版本4的差分升级包(相当于上述的第三差分升级包)，在生成之后，保留第一差分升级包，第三差分升级包，而删除第二差分升级包，这样服务器中存储有版本1和版本2分别到版本4的差分升级包，而不存储中间版本之间的差分升级包，比如版本1和2之间的差分升级包，即服务器存储了所有旧版本到最新版本的差分升级包，当客户端需要升级时，直接将下发对应版本最新的差分升级包给客户端即可。For example: the first version is version 1, the second version is version 2, the third version is version 4; the client needs to upgrade version 1 to version 4, and the server stores a version 1 upgrade to version 2 differential upgrade. The package (equivalent to the second differential upgrade package described above) triggers generation of a differential upgrade package of version 1 to version 4 when the server receives a version 2 to version 4 differential upgrade package (equivalent to the first differential upgrade package described above). (equivalent to the third differential upgrade package described above), after the generation, retain the first differential upgrade package, the third differential upgrade package, and delete the second differential upgrade package, so that the server stores version 1 and version 2 respectively to the version. 4 differential upgrade package, without storing the differential upgrade package between the intermediate versions, such as the differential upgrade package between versions 1 and 2, that is, the server stores all the old versions to the latest version of the differential upgrade package, when the client needs to be upgraded At that time, the latest differential upgrade package of the corresponding version can be directly sent to the client.
在本发明实施例中，服务器中不需要将所有版本都放到服务器上，也不需要在客户端请求升级时将需要的升级包打包在一起下发给客户端，而只需要将差分升级包存储在服务器中，并在需要升级至最新版本时，生成所有旧版本到最新版本的差分升级包，将对应版本的最新的差分升级包下发给客户端，这样节省了服务器大量的存储空间，降低了服务器的维护的成本，同时还具有差分升级的优势。In the embodiment of the present invention, the server does not need to put all the versions on the server, and the upgrade package is not required to be packaged and sent to the client when the client requests the upgrade, but only the differential upgrade package is needed. Stored in the server, and when you need to upgrade to the latest version, generate all the differential upgrade packages from the old version to the latest version, and deliver the latest differential upgrade package of the corresponding version to the client, which saves a lot of storage space of the server. Reduces the cost of server maintenance while also providing the advantage of differential upgrades.
在本发明实施例中，可以通过以下方式生成第三差分升级包：In the embodiment of the present invention, the third differential upgrade package may be generated in the following manner:

需要说明的是，在服务器生成上述第三差分升级包后，还可以删除第二 差分升级包。It should be noted that after the server generates the third differential upgrade package, the second may also be deleted. Differential upgrade package.
举个例子：第一版本为版本1，第二版本为版本2，第三版本为版本4；客户端需要将版本1升级至版本4，而服务器上存储有版本1升级至版本2的差分升级包(相当于上述的第二差分升级包)，当服务器接收到版本2到版本4的差分升级包(相当于上述的第一差分升级包)时，触发生成版本1到版本4的差分升级包(相当于上述的第三差分升级包)，在生成之后，保留第一差分升级包，第三差分升级包，而删除第二差分升级包，这样服务器中存储有版本1和版本2分别到版本4的差分升级包，而不存储中间版本之间的差分升级包，比如版本1和2之间的差分升级包，即服务器存储了所有旧版本到最新版本的差分升级包，当客户端需要升级时，直接将下发对应版本(即本例中的版本1)最新的差分升级包(即本例中的第三差分升级包)给客户端，客户端根据该最新的差分升级包进行升级即可。For example: the first version is version 1, the second version is version 2, the third version is version 4; the client needs to upgrade version 1 to version 4, and the server stores a version 1 upgrade to version 2 differential upgrade. The package (equivalent to the second differential upgrade package described above) triggers generation of a differential upgrade package of version 1 to version 4 when the server receives a version 2 to version 4 differential upgrade package (equivalent to the first differential upgrade package described above). (equivalent to the third differential upgrade package described above), after the generation, retain the first differential upgrade package, the third differential upgrade package, and delete the second differential upgrade package, so that the server stores version 1 and version 2 respectively to the version. 4 differential upgrade package, without storing the differential upgrade package between the intermediate versions, such as the differential upgrade package between versions 1 and 2, that is, the server stores all the old versions to the latest version of the differential upgrade package, when the client needs to be upgraded The latest differential upgrade package (that is, the third differential upgrade package in this example) of the corresponding version (that is, version 1 in this example) is directly sent to the client, and the client is upgraded according to the latest differential upgrade package. It can be.
在本发明实施例中，服务器中不需要将所有版本都放到服务器上，也不需要在客户端请求升级时将需要的升级包打包在一起下发给客户端，而只需要将差分升级包存储在服务器中，并在需要升级至最新版本时，生成所有旧版本到最新版本的差分升级包，将对应版本的最新的差分升级包下发给客户端，客户端根据该最新的差分升级包进行升级即可，这样节省了服务器大量的存储空间，降低了服务器的维护的成本，同时还具有差分升级的优势。In the embodiment of the present invention, the server does not need to put all the versions on the server, and the upgrade package is not required to be packaged and sent to the client when the client requests the upgrade, but only the differential upgrade package is needed. Stored in the server, and when needed to upgrade to the latest version, generate a differential upgrade package from all the old versions to the latest version, and deliver the latest differential upgrade package of the corresponding version to the client, according to the latest differential upgrade package. Upgrade can save a lot of storage space, reduce the cost of server maintenance, and also have the advantage of differential upgrade.
对于服务器通过上述第一差分升级包和第二差分升级包生成第三差分升级包的方法与上述图1所示实施例的生成方法相同，此处不再赘述。The method for generating the third differential upgrade package by the server through the foregoing first differential upgrade package and the second differential upgrade package is the same as the method for generating the embodiment shown in FIG. 1 , and details are not described herein again.
为了更好的理解本发明实施例，以下结合可选实施例对本发明实施例进行解释。For a better understanding of the embodiments of the present invention, the embodiments of the present invention are explained below in conjunction with the alternative embodiments.
本发明实施例提供了一种可选的差分升级包的处理方法：为了便于方法说明，假设用V1、V2、V3表示三个版本，其中V1为最旧的版本，V3为最新的版本。V1-V2表示V1到V2的差分升级包(相当于图1所示实施例中的第二差分升级包)，V2-V3表示V2到V3的差分升级包(相当于图1所示实施例中的第一差分升级包)，V1-V3表示V1到V3的差分升级包(相当于图1所示实施例中的第三差分升级包)。The embodiment of the present invention provides an optional differential upgrade package processing method. For the convenience of the method description, it is assumed that three versions are represented by V1, V2, and V3, where V1 is the oldest version and V3 is the latest version. V1-V2 represents a differential upgrade package of V1 to V2 (corresponding to the second differential upgrade package in the embodiment shown in FIG. 1), and V2-V3 represents a differential upgrade package of V2 to V3 (corresponding to the embodiment shown in FIG. 1) The first differential upgrade package), V1-V3 represents a differential upgrade package of V1 to V3 (corresponding to the third differential upgrade package in the embodiment shown in FIG. 1).
对于差分升级包，其补丁数据结构可以分为(差异数据位置，差异数据 长度，差异数据)和(增加数据位置，增加数据长度，差异数据)，以下将上述两种数据结构统称为补丁数据位置及长度，以及差异数据。图3是根据本发明可选实施例的差分升级包的制作方法的流程示意图，如图3所示，该方法主要步骤包括如下S302～S306：For differential upgrade packages, the patch data structure can be divided into (differential data location, difference data) Length, difference data) and (increase data position, increase data length, difference data), the following two data structures are collectively referred to as patch data position and length, and difference data. FIG. 3 is a schematic flowchart of a method for fabricating a differential upgrade package according to an alternative embodiment of the present invention. As shown in FIG. 3, the main steps of the method include the following S302-S306:
步骤S302，读取V1-V2差分升级包中差分文件的补丁数据位置及长度(相当于图1所示实施例中的第二替换数据的位置及长度)，得到在V2版本对应文件中的位置及长度(相当于图1所示实施例中的第二差异数据的位置及长度)，并记录；Step S302, reading the position and length of the patch data of the difference file in the V1-V2 differential upgrade package (corresponding to the position and length of the second replacement data in the embodiment shown in FIG. 1), and obtaining the position in the corresponding file in the V2 version. And length (corresponding to the position and length of the second difference data in the embodiment shown in FIG. 1), and recorded;
步骤S304，读取V2-V3差分升级包中相同差分文件的补丁数据位置及长度(相当于图1所示实施例中的第一替换数据的位置及长度)，得到在V3版本对应文件中的位置及长度(相当于图1所示实施例中的第一差异数据的位置及长度)，并记录；Step S304, reading the patch data position and length of the same differential file in the V2-V3 differential upgrade package (corresponding to the position and length of the first replacement data in the embodiment shown in FIG. 1), and obtaining the corresponding file in the V3 version corresponding file. Position and length (corresponding to the position and length of the first difference data in the embodiment shown in FIG. 1), and recording;
然后按照如下方式合成新的补丁数据：根据步骤S302记录的V1-V2差分升级包中差分文件的补丁数据在V2对应文件中的位置及长度(相当于图1所示实施例中的第二差异数据的位置范围)进行判断，如果V3中对应文件在该位置开始的长度范围内(相当于图1所示实施例中的第二差异数据的位置范围内)存在补丁数据(相当于图1所示实施例中的第一差异数据)，则将V3对应文件的补丁数据(相当于图1所示实施例中的第一差异数据)合成到V2对应文件的补丁数据(相当于图1所示实施例中的第二差异数据)中，如果V3中应文件的补丁数据(相当于图1所示实施例中的第一差异数据)没有在V1-V2差分升级包中差分文件的补丁数据在V2对应文件中的位置范围(相当于图1所示实施例中的第二差异数据的位置范围)内，则将该补丁数据(相当于图1所示实施例中的第一差异数据)作为新的补丁数据插入。Then, the new patch data is synthesized as follows: the position and length of the patch data of the difference file in the V1-V2 differential upgrade package recorded in step S302 in the V2 corresponding file (corresponding to the second difference in the embodiment shown in FIG. 1) The position range of the data is determined. If the corresponding file in V3 is within the length range starting from the position (corresponding to the position range of the second difference data in the embodiment shown in FIG. 1), there is patch data (corresponding to FIG. 1). In the first difference data in the embodiment, the patch data of the V3 corresponding file (corresponding to the first difference data in the embodiment shown in FIG. 1) is synthesized into the patch data of the V2 corresponding file (corresponding to FIG. 1). In the second difference data in the embodiment, if the patch data of the file in V3 (corresponding to the first difference data in the embodiment shown in FIG. 1) does not have the patch data of the difference file in the V1-V2 differential upgrade package at The V2 corresponds to the position range in the file (corresponding to the position range of the second difference data in the embodiment shown in FIG. 1), and the patch data (corresponding to the first difference data in the embodiment shown in FIG. 1) is taken as New patch data Into.
步骤S306，生成V1-V3的差分升级包(相当于图1所示实施例中的第三差分升级包)。Step S306, generating a differential upgrade package of V1-V3 (corresponding to the third differential upgrade package in the embodiment shown in FIG. 1).
上述步骤S304中，新的补丁数据(相当于图1所示实施例中的第三差分升级包对应的第三替换数据和第三差异数据)根据不同情况生成方式也不同，图4是根据本发明实施例提供的第三差分升级包中的补丁数据的生成示意图，如图4所示，流程如下：左侧图中v1-v2表示在V1版本中需要被替换的 数据的位置及长度(相当于图1所示实施例中的第二替换数据的位置及长度)，v2表示V2相对于V1的差异数据(相当于图1所示实施例中的第二差异数据)，v2-v3表示在v2版本中需要被替换的数据的位置及长度(相当于图1所示实施例中的第一替换数据的位置及长度)。v1表示V3相对于V2的差异数据(相当于图1所示实施例中的第一差异数据)。右侧图中表示新生成的差分升级包，v1-v3表示在V1版本中需要被替换的数据的位置及长度(相当于图1所示实施例中的第三替换数据的位置及长度)，v3表示V3相对于V1的差异数据(相当于图1所示实施例中的第三差异数据)。In the above step S304, the new patch data (corresponding to the third replacement data and the third difference data corresponding to the third differential upgrade package in the embodiment shown in FIG. 1) are also different according to different situations, and FIG. 4 is based on the present invention. A schematic diagram of generating patch data in the third differential upgrade package provided by the embodiment of the present invention is as shown in FIG. 4. The flow is as follows: v1-v2 in the left figure indicates that the V1 version needs to be replaced. The position and length of the data (corresponding to the position and length of the second replacement data in the embodiment shown in FIG. 1), and v2 represents the difference data of V2 with respect to V1 (corresponding to the second difference data in the embodiment shown in FIG. 1) ), v2-v3 indicates the position and length of the data to be replaced in the v2 version (corresponding to the position and length of the first replacement data in the embodiment shown in FIG. 1). V1 represents the difference data of V3 with respect to V2 (corresponding to the first difference data in the embodiment shown in Fig. 1). The newly generated differential upgrade package is shown in the right figure, and v1-v3 indicates the position and length of the data to be replaced in the V1 version (corresponding to the position and length of the third replacement data in the embodiment shown in FIG. 1). V3 represents the difference data of V3 with respect to V1 (corresponding to the third difference data in the embodiment shown in Fig. 1).
如果v1-v2和v2-v3存在数据交叉，则v1-v3的起始位置及长度由v1-v2，v2及v2-v3来确定，位置确定方法：如果v2-v3起始位置在v2的范围内，则v1-v3的起始位置为v1-v2的起始位置；如果v2-v3起始位置在v2左侧，则v1-v3的起始位置为v2-v3的起始位置减去当前V2中相对于V1中增加的长度；长度确定方法：如果v2-v3长度在v2范围内则最终长度即为v1-v2的长度，如果v2-v3长度在v2的范围外则最终长度为v1-v2的长度加上v2-v3超出v2的结束位置的长度。V3相对于V1的差异数据由V2相对于V1的差异数据，和V3相对于V2的差异数据合并得到，合并方式如下：将V3相对于V2的差异数据覆盖到V2相对于V1的差异数据重叠部分，剩余部分直接使用。If there is data intersection between v1-v2 and v2-v3, the starting position and length of v1-v3 are determined by v1-v2, v2 and v2-v3, and the position determining method: if the starting position of v2-v3 is in the range of v2 Inside, the starting position of v1-v3 is the starting position of v1-v2; if the starting position of v2-v3 is to the left of v2, the starting position of v1-v3 is the starting position of v2-v3 minus the current position The length of V2 is increased relative to V1; the length is determined by the method: if the length of v2-v3 is in the range of v2, the final length is the length of v1-v2. If the length of v2-v3 is outside the range of v2, the final length is v1- The length of v2 plus the length of v2-v3 beyond the end position of v2. The difference data of V3 with respect to V1 is obtained by combining the difference data of V2 with respect to V1 and the difference data of V3 with respect to V2, and the combination is as follows: the difference data of V3 with respect to V2 is covered to the overlap of the difference data of V2 with respect to V1 The rest is used directly.
如果v1-v2和v2-v3不存在数据交叉，则v1-v3的起始位置由v2-v3的起始位置对应于V2当前位置相对于V1改变了多少获得。数据长度及差异数据保持为v2-v3的。If there is no data intersection between v1-v2 and v2-v3, the starting position of v1-v3 is obtained by how much the starting position of v2-v3 corresponds to how the current position of V2 changes relative to V1. The data length and difference data are kept as v2-v3.
通过以上的实施方式的描述，本领域的技术人员可以清楚地了解到根据上述实施例的方法可借助软件加必需的通用硬件平台的方式来实现，当然也可以通过硬件，但很多情况下前者是更普遍的实施方式。基于这样的理解，本发明实施例的技术方案本质上或者说做出贡献的部分可以以软件产品的形式体现出来，该计算机软件产品存储在一个存储介质(如ROM/RAM、磁碟、光盘)中，包括一条或多条指令用以使得一台终端设备(可以是手机，计算机，服务器，或者网络设备等)执行本发明实施例所述的方法。Through the description of the above embodiments, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course, by hardware, but in many cases, the former is A more general implementation.

The method includes the one or more instructions for causing a terminal device (which may be a mobile phone, a computer, a server, or a network device, etc.) to perform the method described in the embodiments of the present invention.
在本发明实施例中还提供了一种升级系统，该系统用于实现上述实施例 及可选实施方式，已经进行过说明的不再赘述。An upgrade system is further provided in the embodiment of the present invention, and the system is used to implement the foregoing embodiment. And optional embodiments, which have already been described, are not described again.
图5是根据本发明实施例提供的升级系统的示意图，如图5所示，该系统包括：服务器52，客户端54；所述客户端54设置成向所述服务器52发送将指定软件的第一版本升级至第三版本的升级请求；所述服务器52设置成存储所述指定软件的第一版本到第二版本的第二差分升级包，在接收到所述指定软件的第二版本到第三版本的第一差分升级包时，触发生成所述指定软件的第一版本到第三版本的第三差分升级包；以及接收到所述升级请求时将所述第三差分升级包下发至所述客户端54。5 is a schematic diagram of an upgrade system according to an embodiment of the present invention. As shown in FIG. 5, the system includes: a server 52, a client 54; the client 54 is configured to send a message to the server 52 that specifies software. Upgrading a version to a third version of the upgrade request; the server 52 is configured to store a second differential upgrade package of the first version to the second version of the specified software, upon receiving the second version of the specified software to the first The third differential upgrade package of the third version is triggered to generate a third differential upgrade package of the first version to the third version of the specified software; and the third differential upgrade package is sent to the upgrade request when the upgrade request is received The client 54.
通过上述系统，采用在客户端54需要从第一版本升级至第三版本的情况下，服务器52通过第二版本到第三版本的第一差分升级包和预先存储的第一版本到第二版本的第二差分升级包来生成从第一版本升级至第三版本的第三差分升级包，然后直接将第三差分升级包下发给客户端54的方案，解决了相关技术中升级包制作和维护工作量大的问题，达到了减少了升级包制作和维护的工作量的目的，提高了版本升级的效率，降低了维护的成本。With the above system, in the case where the client 54 needs to be upgraded from the first version to the third version, the server 52 passes the first differential upgrade package of the second version to the third version and the pre-stored first version to the second version. The second differential upgrade package is configured to generate a third differential upgrade package that is upgraded from the first version to the third version, and then directly delivers the third differential upgrade package to the client 54 to solve the related art upgrade package creation and The problem of maintaining a large workload has reduced the workload of the upgrade package production and maintenance, improved the efficiency of the version upgrade, and reduced the maintenance cost.
在本发明实施例中，上述服务器52还可以设置成在生成第三差分升级包之后，删除第二差分升级包。In the embodiment of the present invention, the server 52 may be further configured to delete the second differential upgrade package after generating the third differential upgrade package.
举个例子：第一版本为版本1，第二版本为版本2，第三版本为版本4；客户端54需要将版本1升级至版本4，而服务器52上存储有版本1升级至版本2的差分升级包(相当于上述的第二差分升级包)，当服务器52接收到版本2到版本4的差分升级包(相当于上述的第一差分升级包)时，触发生成版本1到版本4的差分升级包(相当于上述的第三差分升级包)，在生成之后，保留第一差分升级包，第三差分升级包，而删除第二差分升级包，这样服务器52中存储有版本1和版本2分别到版本4的差分升级包，而不存储中间版本之间的差分升级包，比如版本1和2之间的差分升级包，即服务器52存储了所有旧版本到最新版本的差分升级包，当客户端54需要升级时，直接将下发对应版本最新的差分升级包给客户端54即可。For example: the first version is version 1, the second version is version 2, the third version is version 4; the client 54 needs to upgrade version 1 to version 4, and the server 52 stores version 1 upgrade to version 2 a differential upgrade package (corresponding to the second differential upgrade package described above), when the server 52 receives the version 2 to version 4 differential upgrade package (corresponding to the first differential upgrade package described above), triggering generation of version 1 to version 4 The differential upgrade package (equivalent to the third differential upgrade package described above), after the generation, retains the first differential upgrade package, the third differential upgrade package, and deletes the second differential upgrade package, so that the server 52 stores the version 1 and the version. 2 separately to the version 4 differential upgrade package, without storing the differential upgrade package between the intermediate versions, such as the differential upgrade package between versions 1 and 2, that is, the server 52 stores all the old versions to the latest version of the differential upgrade package. When the client 54 needs to be upgraded, the latest differential upgrade package of the corresponding version is directly sent to the client 54.
在本发明实施例中，服务器52中不需要将所有版本都放到服务器52上，也不需要在客户端54请求升级时将需要的升级包打包在一起下发给客户端54，而只需要将差分升级包存储在服务器52中，并在需要升级至最新版本时， 生成所有旧版本到最新版本的差分升级包，将对应版本的最新的差分升级包下发给客户端54，这样节省了服务器52大量的存储空间，降低了服务器52的维护的成本，同时还具有差分升级的优势。In the embodiment of the present invention, the server 52 does not need to put all the versions on the server 52, and the upgrade package is not required to be packaged and sent to the client 54 when the client 54 requests the upgrade. The differential upgrade package is stored in the server 52 and when it is necessary to upgrade to the latest version, The differential upgrade package of all the old versions to the latest version is generated, and the latest differential upgrade package of the corresponding version is sent to the client 54, which saves a large amount of storage space of the server 52, reduces the maintenance cost of the server 52, and also has The advantages of differential upgrades.

为了更好的理解本发明实施例，以下结合可选的实施例对本发明实施例进行解释。For a better understanding of the embodiments of the present invention, the embodiments of the present invention are explained below in conjunction with the optional embodiments.
本发明实施例提供了一个可选的升级系统；该升级系统包括：升级包制 作工具，客户端，服务器。图8是根据本发明可选实施例的升级系统对差分升级包的处理流程图，如图8所示，该处理流程包括如下步骤S802～S808：An embodiment of the present invention provides an optional upgrade system; the upgrade system includes: an upgrade package system As a tool, client, server. FIG. 8 is a flowchart of processing a differential upgrade package by an upgrade system according to an alternative embodiment of the present invention. As shown in FIG. 8, the process flow includes the following steps S802-S808:
步骤S802，上传最新版本与前一版本的差分升级包；Step S802, uploading a differential upgrade package of the latest version and the previous version;
步骤S804，服务器读取所有已存在的差分升级包；Step S804, the server reads all existing differential upgrade packages;
步骤S806，生成所有旧版本到最新版本的差分升级包；Step S806, generating a differential upgrade package of all the old versions to the latest version;
步骤S808，根据终端请求信息下发对应的升级包。Step S808: The corresponding upgrade package is delivered according to the terminal request information.
上述步骤介绍了升级包制作，服务器对升级包的处理，以及服务器对客户端的响应。升级包制作时只需要制作最新版本相对于前一版本的差分升级包(相当于上述实施例中的第一差分升级包)，服务器对升级包的处理为服务器上如果已上传旧版本的差分升级包(相当于上述实施例中的第二差分升级包)，当上传新版本的差分升级包(相当于上述实施例中的第一差分升级包)时，触发上述差分升级包制作工具，自动生成新的差分升级包(相当于上述实施例中的第三差分升级包)，服务器对客户端的响应为客户端请求升级时服务器直接下发对应版本最新的差分升级包。例如服务器上当前有V1-V2的差分升级包，上传V2-V3的差分升级包时，则服务器根据V1-V2及V2-V3的差分升级包自动生成V1-V3的差分升级包同时删除V1-V2的差分升级包，保留V2-V3的差分升级包。目前服务器上存在V1-V3和V2-V3的差分升级包，当用户以V1检测升级包时则下发V1-V3的升级包，用户以V2检测升级包时则下发V2-V3的升级包。如果又上传了V3-V4的差分升级包，则服务器自动生成V1-V4、V2-V4的差分升级包并对相应的用户请求进行升级。The above steps describe the upgrade package creation, the server's handling of the upgrade package, and the server's response to the client. The upgrade package only needs to make the differential upgrade package of the latest version relative to the previous version (equivalent to the first differential upgrade package in the above embodiment), and the server processes the upgrade package as if the old version of the differential upgrade has been uploaded on the server. The packet (corresponding to the second differential upgrade package in the foregoing embodiment), when uploading a new version of the differential upgrade package (corresponding to the first differential upgrade package in the foregoing embodiment), triggering the differential upgrade package creation tool to automatically generate A new differential upgrade package (equivalent to the third differential upgrade package in the above embodiment), the server responds to the client, and the server directly delivers the latest differential upgrade package of the corresponding version when the client requests the upgrade. For example, if there is a V1-V2 differential upgrade package on the server and a V2-V3 differential upgrade package is uploaded, the server automatically generates a V1-V3 differential upgrade package according to the V1-V2 and V2-V3 differential upgrade packages and deletes V1-. The V2 differential upgrade package retains the V2-V3 differential upgrade package. Currently, there are V1-V3 and V2-V3 differential upgrade packages on the server. When the user detects the upgrade package with V1, the V1-V3 upgrade package is delivered. When the user detects the upgrade package with V2, the V2-V3 upgrade package is delivered. . If the V3-V4 differential upgrade package is uploaded, the server automatically generates a differential upgrade package for V1-V4 and V2-V4 and upgrades the corresponding user request.
