Detailed Description

Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to like or similar elements or elements having like or similar functions throughout. The embodiments described below by referring to the drawings are illustrative only and are not to be construed as limiting the invention. The step numbers in the following embodiments are set for convenience of illustration only, and the order between the steps is not limited in any way, and the execution order of the steps in the embodiments may be adaptively adjusted according to the understanding of those skilled in the art.

First, terms related to the embodiments of the present application will be explained, specifically:

breakpoint continuous downloading: in the downloading process of large files, most of downloaded software uses breakpoint downloading technology, and the principle is that: and fragmenting the file, marking the fragmented file, then downloading the fragmented file, reorganizing the data stream after the downloading is completed, and writing the data stream into the local file.

Differential packet: and comparing the reference package (original file) with the modified latest file through a difference algorithm (bsdiff algorithm) to obtain a differential patch file.

Patch combination: patch combining is a process of combining file differential packets and reference packets by a differential algorithm (bspatich algorithm).

Incremental update: incremental update refers to that when an update operation is performed, only the place needing to be changed is updated, and the updated update is not repeated. The principle is that a place with a new version different from an old version is found out through a difference algorithm, then the place which is different is extracted to form an update patch, when a client detects the update, only a difference packet is downloaded to the local, and then the difference packet is combined into a local original file packet to form a new file packet, so that the effect of quick update is achieved.

Reference package: for example, the file a is modified to obtain the file B, and then the file a is the reference package of the file B.

Full update: the full-volume update refers to that when the update operation is performed, the whole complete file package needs to be downloaded and then subjected to the overlay update.

Along with the rapid development of mobile applications, the related fields are wide, the requirements of most enterprises on the mobile applications are larger and larger, the related links and functions are more and more, the size of an apk installation package is continuously increased, the pressure on server resources is more and more increased in the APP updating process, the loss of flow in the user downloading process is also continuously increased, the user downloading and updating time is also influenced, and unfriendly user embodiment is caused. Meanwhile, in the business demands of the day and month, the rapid iteration modes of small programs, offline packages and the like are also induced, but the modes also need to depend on the downloading and updating functions.

Therefore, the following disadvantages exist in the conventional update method: for direct downloading, the downloading process of the user must be carried out once, such as the common scenes of network abnormality, network jitter, active exit of the user and the like, which occur in the downloading process, and the downloading is interrupted, so that the downloading needs to be restarted from zero. This is very wasteful of server resources and traffic and also very affects the user experience. Version updating method of full update: the complete file package needs to be downloaded, so that the server pressure is increased, the server resources are occupied greatly, the downloading flow of a user is increased, the waiting time of the user for downloading is prolonged, and the like. The single download updating mode, the traditional downloading mode, does not have the concepts of multi-file and multi-version management, and the single download can not meet the requirement in the business scenes such as small programs, offline packages and the like.

The main disadvantages of many existing downloading technologies are basically concentrated on: the server resources are large in occupied amount, the traffic is large in use, the downloading time is too long or breakpoint downloading cannot be used, or file downloading does not carry out safety check, file tampering is prevented, multi-file and multi-version management cannot be carried out, and the like. The file downloading and updating system aims to solve the defects. Based on the above technical background and user experience requirements, there are some ways of single increment update, single breakpoint download and the like at present, but it is difficult to better meet the above requirements at the same time.

The method and system for updating a version of a file according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings, and first, the method for updating a version of a file according to an embodiment of the present invention will be described with reference to the accompanying drawings.

Referring to fig. 1, a method for updating a version of a file is provided in an embodiment of the present invention, and the method for updating a version of a file in an embodiment of the present invention may be applied to a terminal, a server, software running in a terminal or a server, and the like. The terminal may be, but is not limited to, a tablet computer, a notebook computer, a desktop computer, etc. The server may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDNs, basic cloud computing services such as big data and artificial intelligent platforms. The version updating method of the file in the embodiment of the invention mainly comprises the following steps:

s100: acquiring local cache file information;

s200: matching the local cache file information with the target file information through a network request; storing the target file information in a file server; the version of the target file information is the latest version;

s300: if the local cache file information and the target file information are not successfully matched, and the local cache file information meets the condition of an incremental updating mechanism, receiving a differential packet; the incremental updating mechanism condition is used for representing the version and the security condition to be met by the local cache file, and the differential packet is generated by the file management platform according to the local cache file information and the target file information;

s400: and carrying out patch combination processing on the local cache file and the differential packet to generate a target version file, and carrying out version updating on the file according to the target version file.

In some possible implementations, to reduce resource consumption and waste during downloading, the embodiments of the present application introduce a design scheme of incremental update. Referring to fig. 2, by comparing the local version cache (i.e., the local cache file) with the target file information through network matching, it is checked whether the two are identical. If the files are consistent, the local version cache can be used for updating the files. If not, the updated portion (i.e., differential packet) of the target file information is used for version updating of the file.

In some possible implementations, referring to fig. 3, the file management platform uses a full-volume packet a (reference packet) and a full-volume packet B, and generates a differential packet B1 in cooperation with a differential algorithm, an APP container obtains the differential packet B1 in a file server through a network, and then combines the differential packet B with the full-volume packet a (reference packet) locally cached by the APP container, and cooperates with the differential algorithm to form the full-volume packet B, so as to implement iterative update of the file. The problem that the whole file must be completely downloaded and the local version coverage iteration is carried out in the file updating iteration process is avoided. This can greatly reduce the amount of resources occupied and the stress on the server. Specifically: the APP container can read the local version cache information first, and performs file matching with the file server through the network request, whether the file needs to be updated or not, and if the version of the APP container is consistent with the version of the file server file, the APP container can be directly used for locally caching the file. If the file server is inconsistent with the local file version, the file server can judge whether the use increment updating condition (version and safety check) is met according to the local version cache information of the APP container, and if the use increment updating condition is not met, the APP container is required to download the full package again for use. If the increment updating mechanism condition is met, the file server can issue differential packets according to the version information of the APP local cache. After the App container downloads the differential packet, the App container performs patch combination and splicing with the reference packet of the corresponding version locally cached by the App container through a differential algorithm to perform version iterative updating.

It can be seen from this: the buffer mechanism occupies an important position in the embodiment of the invention, and the buffer mechanism needs to be used throughout the whole process of downloading the file to the patch combination. The method is a bridge of the functions, and records all file version information, file downloading cache information, file foundation packages and the like, wherein the information carries the foundation conditions of functions such as downloading update, incremental update, security check, version management and the like.

The invention is directed to a multi-file management download update function which can cope with multi-file and multi-version management mechanisms. The file creates a unique item ID when the file management platform is first uploaded. Based on this item ID, file discrimination management is performed. And each item ID may be assigned to a different version of the file. Thus, multi-file and multi-version management can be realized. The file updating and downloading function is more flexible and practical. Based on the application engineering frameworks such as the applet frameworks, the offline package frameworks and the like developed by the application platform of the mobile terminal, the multi-file and multi-version management downloading and updating applet package/offline package functions are needed. The invention can provide the mobile phone terminal application framework with the function of quickly accessing the file downloading update version management, and once accessed, the mobile phone terminal application framework directly has a whole set of multi-file downloading update capability for multi-version management without any judgment processing of a user.

Optionally, in one embodiment of the present invention, the method further comprises:

the file server is used for storing target file information and differential packets;

the terminal container is used for receiving the differential packets and is also used for updating the version of the file.

In some possible embodiments, in order to meet the urgent needs in the current technical background, the overall technical architecture of the present invention is shown in fig. 4, and is generally divided into three layers, namely, a file management platform, a static resource server and an APP container environment. The file management platform mainly comprises the following functions: account management, file version management, log management and incremental update management; APP container environmental functions include; host protocol, breakpoint mechanism, security mechanism, cache mechanism, incremental update mechanism, file version management and other major functions; static resource server function: is responsible for storing the file package.

The invention has the main functions of realizing incremental update of files, breakpoint continuous downloading, file version management, a safety mechanism and the like by closely matching three layers, solving the problems of long-time occupation pressure and bandwidth pressure on server resources, reducing user downloading flow, reducing user downloading time, avoiding redundant file generation and waste of resources such as flow and the like and solving downloading service requirements of multi-file and multi-version management caused by APP in a downloading failure scene of weak network disconnection.

Optionally, in one embodiment of the present invention, receiving the differential packet includes:

if the target temporary file exists locally, acquiring a first data length of the local target temporary file; the differential package comprises a target temporary file;

In some possible embodiments, the receiving of the differential packet and the receiving of the target file information in the embodiments of the present application may use a breakpoint continuous downloading manner, so as to save downloading flow and time, and a specific flow is shown in fig. 5, including: downloading a file, caching the local file, downloading and writing the residual length according to the existing length of the file, reconnecting after downloading is interrupted, checking the integrity of the file, and the like. The breakpoint downloading function makes up for the mode that the traditional downloading cannot be reconnected after the interruption, thereby reducing the waste of resources and flow of the interruption of the downloading, accelerating the whole downloading time and improving the user experience.

In some possible embodiments, during the network transmission process and during the local cache, there may be security problems such as file tampering, so in the present invention, a security check mechanism is introduced to ensure the security of the file. The flow chart of the security verification mechanism is shown in fig. 6, and the security mechanism is to utilize algorithms such as MD5 to correct the integrity of the downloaded file and the local file through the local cache information of the APP container in the file version iteration process. The APP container takes the local cache file information, checks the safety and the integrity of the file through a network request and a file server, and if the safety check is not passed, deletes the local cache file data at the same time, and downloads the full package; if the security check passes, differential or full packet downloads may be performed. And (3) after the downloading is finished, carrying out the security check of the file obtained by final downloading, and processing and using the file according to the corresponding business logic through the final security check. Such a security mechanism ensures security when locally caching the file and security when transmitting the file in a network connection.

Optionally, in an embodiment of the present invention, if the local cache file information and the target file information are not successfully matched, and the local cache file information meets the condition of the incremental update mechanism, receiving the differential packet includes:

if the local cache file information and the target file information are not successfully matched, and the local cache file information is successfully matched with the reference packet, receiving the differential packet; the reference package is used for representing the file with the version before the version of the target file; the differential packet is a differential patch file between the reference packet and the target file information.

In some possible implementations, the differential packet in the embodiments of the present application refers to a differential patch file between the reference packet and the target file information, and by receiving the differential packet, the flow consumption and the downloading time of file update are reduced, so that the user experience is improved.

if the local cache file information and the target file information are not successfully matched, and the local cache file information and the reference packet are not successfully matched, receiving a full packet; the full package is stored in the file server, and the full package comprises target file information;

and determining a second number of differential packets to be received according to the number of versions, wherein the second number is equal to the number of versions.

In some possible embodiments, the number of versions, that is, the number of versions, that the local cache file differs from the current target file information before is obtained by detecting which reference packet the local cache file matches. The number of differential packets to be received is determined according to the number of versions, so that the accuracy of version updating is improved.

In summary, the invention provides a multi-file and multi-version file downloading and updating scheme based on a mobile application mobile phone terminal, which comprises a file management platform, a static resource server and an APP container environment, wherein the file management platform mainly comprises the following functions: account management, file version management, log management and incremental update management; APP container environmental function package: host protocol, breakpoint mechanism, security mechanism, cache mechanism, incremental update mechanism, file version management and other major functions; static resource server function: is responsible for storing the file package. The user can realize the file downloading and updating function fast by accessing the APP container environment and operating with the simple file management platform, and the downloading and updating function can automatically download and update the file according to different states (the specific principle can refer to a file complaint flow chart), and the user does not need to select. The access cost of the user is reduced to the minimum.

The embodiment of the invention mainly provides version updating mechanisms including breakpoint continuous transmission, increment updating, a caching mechanism, a security mechanism, a version management mechanism and the like, and specific implementation steps and function interaction modes of functions related to each mechanism. Compared with the related art, the embodiment of the invention realizes that a developer can realize a multi-file and multi-version file updating scheme by integrating the APP container environment framework into the application program without modifying the original code, thereby reducing the workload and the maintenance cost. The embodiment of the invention is suitable for various file downloading and updating service requirements, such as various downloading service scenes of offline packages, applets, application markets and the like. Compared with the traditional downloading and updating mode, the embodiment of the invention can better save server resources and file downloading flow, reduce downloading time and better ensure file security by introducing a security mechanism.
