Detailed Description
Preferred embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
As previously mentioned, existing target file distribution or download schemes still suffer from serious deficiencies. For example, taking an installation package file of an application APP as an example, for the same application, different user characteristics, distribution channels, advertisement identifiers of the application system itself, and other characteristics all cause some identification files in the application installation package file to be different, and even though the part of the file occupies a small part of the application installation package file, installation package files of different versions of the same application may also be caused.
In the existing technical solution, a plurality of application installation package files with differentiation are generally divided into two parts: all installation files include one common file portion and a plurality of differential file portions having differences. There are two different file distribution schemes:
in the first aspect, application installation package files of each version with different characteristics are stored in a server, and when a user needs the application installation files requested by the user are sent to a client for installation and use.
In the second aspect, the client downloads the public file part of the application APP requested by the user, then downloads the corresponding differentiated file part, and then assembles the public file part and the differentiated file part into a new installation package file at the client for installation and use.
However, the distribution scheme of the first aspect occupies too much storage space of the server, the technical scheme of the second aspect consumes a large amount of CPU resources of the client, and the installation time is too long, which also greatly reduces the installation success rate and brings bad experience to the user.
Therefore, the invention provides an improved target file distribution scheme to save server storage resources and client CPU resources and improve user experience.
In the technical scheme of the invention, the target file refers to a specific file requested when a user (or a client) sends a file downloading request. Any file may be the target file of the present invention, which may include but is not limited to a text document, a picture, a program, or a combined package of multiple file components, and the present invention is not limited thereto.
It should also be understood by those skilled in the art that the installation file of the APP is taken as the target file, which is only illustrative and not limiting.
The technical solution of the present invention will be described in detail with reference to the accompanying drawings and embodiments.
FIG. 1 shows a schematic diagram of a target file distribution system according to one embodiment of the invention.
As shown in fig. 1, the target file distribution system may include one server 20 and a plurality of terminal devices 10. The terminal device 10 can transmit and receive information to and from the server 20 via the network 40. The server 20 can acquire contents required by the terminal device 10 by accessing the database 30. Network 40 may be a network for information transfer in a broad sense and may include one or more communication networks such as a wireless communication network, the internet, a private network, a local area network, a metropolitan area network, a wide area network, or a cellular data network, among others.
It should be noted that the underlying concepts of the exemplary embodiments of the present invention are not altered if additional modules are added or removed from the illustrated environments. In addition, although a bidirectional arrow from the database 30 to the server 20 is shown in the figure for convenience of explanation, it will be understood by those skilled in the art that the above-described data transmission and reception may be realized through the network 40.
The terminal device 10 is any suitable electronic device, preferably a mobile device, including but not limited to a smartphone, tablet, or other client, that can be used for network access. The server 20 is any server capable of providing information required for an interactive service through a network. And one or a part of them will be selected for description in the following description (for example, the terminal device 10-1), but it should be understood by those skilled in the art that the above-mentioned 1 … N mobile terminals are intended to represent a large number of mobile terminals existing in a real network, and the single server 20 and database 30 shown are intended to represent that the technical solution of the present invention relates to the operation of the server and the database. The detailed description of the mobile terminal and the single server and database with specific numbers is at least for convenience of description and does not imply any limitation as to the type or location of the mobile terminal and server.
In a preferred embodiment, the server 20 may be a cloud server, and the database 30 may also be a disk space stored in the cloud server.
It will be understood by those skilled in the art that in the present invention, "user," "client" and "terminal device" may be used interchangeably herein, as not expressly stated. Moreover, the descriptions of "first" and "second" herein are intended to distinguish between the objects of description, and not to specify any order or magnitude by which the objects may be claimed.
Fig. 2 shows a schematic diagram of an implementation mechanism of a target file distribution system according to an embodiment of the invention.
As shown in fig. 2, when a user sends a target file download request to a server via a client, the server configures adaptive personalized information for the user according to user information and/or client information included in the download request, and sends the configured personalized information to the client of the user. Meanwhile, the server can determine file components included in the target file suitable for the personalized information based on the personalized information, and further determine component position information of each file component in the target file.
Therefore, the server can respond to the blocking downloading request from the user client, determine the file assembly where the file block requested to be downloaded by the blocking request is located based on the assembly position information and the position range requested to be downloaded by the blocking request, and send the file block data corresponding to the determined file assembly to the user client.
So far, the implementation mechanism of the present invention is briefly described, and the following describes in detail the specific implementation process of the present invention with reference to specific embodiments.
FIG. 3 shows a schematic flow diagram of a target file distribution method according to one embodiment of the present invention. The method may be implemented on the server side as shown in fig. 1. Among them, the method shown in fig. 3 can be applied to various object files.
Referring to fig. 3, in step S310, file components included in a target file suitable for personalized information are determined based on the personalized information of the user.
The target file mentioned herein refers to a specific file requested when a user (or client) makes a file download request. It should be understood that any file may be the target file of the present invention, which may include but is not limited to a text document, a picture, a program or a combined package of multiple files, and the present invention is not limited thereto.
In the invention, the target file can be formed by one or more file components, the file components refer to files forming the target file, and each file component can comprise a plurality of file blocks. The target file and the file components may preferably be ZIP formatted files. Also, the target file and/or each file component may include file content, a file index, basic information of the file, and the like.
The personalized information may be configured by the server for the user or the client thereof, and the personalized information may include identification information of the file component included in the target file suitable for the client, and the representation information may include, but is not limited to, a file component name, a file component number or other representation information.
When a user wishes to obtain a certain file, the user sends a target file downloading request to the server through the client, the downloading request may include user information and/or client information, and the user information and/or client information may include, but is not limited to, a user ID, a device type of the client, a user IP address, and the like. After receiving the download request, the server may configure personalized information suitable for the user and/or the client based on the user information and/or the client information. In this way, the server can determine the file components that are included in the target file that are appropriate for the personalized information.
The personalized information may be configured by the server in real time in response to a download request of the user, or may be configured by the server when idle based on user information or client information. In a preferred embodiment, the configured personalized information can be issued to the user client, so that when the user issues the target file downloading request, the personalized information can be issued in association with the target file downloading request, so that the server can quickly determine the appropriate file components according to the personalized information.
Then, in step S320, the server may determine component location information of each file component in the target file.
The component position information is the position information of each file component in the target file, and can be determined according to the file information of each file component or the target file meta information. The meta information is information about information, and is used to describe the structure, semantics, usage, and the like of the information. The target file meta information is information about the target file and may include, but is not limited to, the size of the target file, the location of the target file content, the location of the target file index, the target file information content, and so on.
In a preferred embodiment, the server may find a first file component and a second file component suitable for the personalized information, and construct the target file meta information based on the first file information of the first file component and the second file information of the second file component. Component location information for each file component in the target file may be determined based on the target file meta-information.
Here, the first file component may preferably include first file content, a first file index, first file information, and the second file component may preferably include second file content.
The target file meta information may include: the location of the first file index in the target file, the location of the second file content in the target file, the location of the target file index in the target file, the size of the target file, the file information content of the target file, and the like. Wherein the second file content may be between the first file content and the first file index, and the target file index is between the second file content and the information content of the target file.
The target file index may include a first file index and a second file index, which may be constructed from the first file information and the second file information while constructing the target file meta information.
In a more preferred embodiment, the server may determine an insertion position of second file content in the first file component suitable for the second file component based on the first file information of the first file component, and construct the target file meta information based on the first file information of the first file component, the second file information of the second file component, and the insertion position. At this time, the target file index may be constructed according to the first file index, the second file content, and the insertion position in the process of constructing the target file meta information.
The insertion location is the location where a second file component is to be inserted in the first file component, which may be a one byte location marker. In a preferred embodiment, the server may perform a preprocessing operation on each file component in advance, for example, add a location identifier indicating an insertion location in the first file component.
When the second file component includes only the second file content, the insertion location may preferably be located at the end of the first file content. When the second file component includes the second file content, the second file index, and the second file information content, the insertion position may be located at the end of the first file content, the end of the first file index, and the end of the first file information content, respectively. Therefore, the corresponding insertion position of the second file component can be quickly determined according to the index information of the first file.
If the contents of the second file element are inserted into the insertion position and the space occupied by the contents of the second file is more than one byte, the element positions of the respective file elements of the target file are shifted. Thus, the above-mentioned target file meta information may further include offset or end position information of the respective file components, e.g., a second file content offset position, a second file content end position, a second file index offset position, a second file index end position, a target file index offset position.
The constructed target file meta information may be stored in association with personalized information of the user. When the server receives a download request sent by the client and configures the corresponding personalized information for the download request, the server can preferentially search the meta information of the target file suitable for the personalized information. And under the condition that the target file meta-information is found, determining the component position information of each file component according to the found target file meta-information. And under the condition that the target file meta-information is not found, the step of constructing the target file meta-information based on the first file information of the first file component and the second file information of the second file component is executed so as to determine the component position information of each file component.
Then, in step S330, in response to the block downloading request from the user client, based on the component location information and the location range requested to be downloaded by the block downloading request, the server may determine a file component in which the file block requested to be downloaded by the block downloading request is located, and send the file block data corresponding to the determined file component to the user client.
The client may request data, which may be chunk requested, preferably via the HTTP protocol. For example, 1-100 bytes are requested for the first time and 101-200 bytes are requested for the second time. The server firstly determines the insertion position of the second file component, for example, the insertion position is inserted into the 500-plus 660-byte interval, and when the client requests the corresponding byte segment, the server sends the corresponding file block data of the corresponding file component, thereby realizing the ZIP binary stream type package downloading of the target file. Therefore, the file block data of the corresponding file assembly is directly transmitted to the client in a streaming manner without additional storage space or file decompression or repackaging at the client, streaming downloading of the target file is realized, and resources of the server and the client are greatly saved.
The target file as described above may have different versions for different properties. Therefore, in a preferred embodiment of the present invention, the first file component may be a common file component included in all versions of the target file, and the second file component may be a differential file component prepared for personalized information of the user.
Therefore, the server can only store one public file assembly and a plurality of differential file assemblies without storing target files of all versions, and the storage space of the server can be greatly saved.
As the common file component, it may need to be frequently called when distributing different versions of the target file, therefore, in a preferred embodiment, for a first file component that is used more frequently, it may also be cached in the cache of the server, and for all second file components that are not used frequently, it may be stored in the background storage space of the server instead of caching in the cache of the server.
Therefore, after receiving a target file downloading request of a user, the server can rapidly issue corresponding file block data to the client, and therefore file distribution efficiency is improved.
Further, in a preferred embodiment, the server may perform a preprocessing operation on the first/second file components before step S210. The preprocessing operations may or may not be identical for different file components. For example, the preprocessing operation may include adding a location identifier to indicate an insertion location in the first file component. Or the preprocessing operation may also include corresponding channels for each file in the second file component, and so on.
The object file distribution scheme of the present invention can also be implemented as an object file downloading method, and fig. 4 shows a schematic flowchart of an object file downloading method according to an embodiment of the present invention. The method may be implemented on the client side as shown in fig. 1.
As shown in fig. 4, in step S410, a target file download request is sent to the server, where the download request includes user information and/or client information.
In step S420, personalized information configured by the server based on the user information and/or the client information is received, the personalized information including identification information of file components included in the target file suitable for the client.
In step S430, the personalization information is sent to the server to request the chunking download of the target file.
The client can receive the file block data sent by the server. After downloading, the target file can be directly browsed or used by a user, file decompression or repackaging is not needed to be carried out on the application installation file at the client, the CPU resource of the client is greatly saved, the application installation time is shortened, and the user experience is improved.
So far, the technical scheme of the invention has been explained in detail by combining with the figures 3-4.
[ application example ]
For better understanding of the present invention, the following description will take an installation file of an APP as an example of an object file of the present invention.
Based on different user characteristics, device types, distribution channels, etc., the same target application may have different versions of installation files, each version of installation files being not identical. For example, for the same application, based on different operating systems (e.g., Android, iOS, Windows), different devices (e.g., apple, association, dell, goicho, hua, samsung, etc.), different device types (e.g., association ideal Pad and ThinkPad, etc.), different distribution channels (e.g., application marketplace, application store, 91 assistant, 360 butler), etc. Although the differentiated file only occupies a very small memory, the storage space occupied by all versions of installation files is very large, and if the server stores all installation files, the storage space is greatly wasted.
In this application example, the file parts included in all the target files are regarded as the common files as the first file components of the target files, and the differentiated file parts aiming at the personalized information of the user are regarded as the differentiated files and regarded as the second file components of the target files. It should be understood that in the present invention, the same application may preferably have one common file and one or more differential files.
The server may perform a preprocessing operation on the first/second file components in advance. For example, a location identifier for indicating an insertion location of a differentiated document is added to the public document, and different advertisement identifiers and distribution channels are correspondingly corresponding to the differentiated documents, for example, channel 1 corresponds to differentiated document 1, channel 2 corresponds to differentiated document 2 … …, channel n corresponds to differentiated document n, and so on.
The common file and each differentiated file may be stored in a background storage space of the server. In a preferred embodiment, the common files which are used more frequently can be preferentially cached in a cache area of the server, and the different files which are used less frequently are stored in a background storage space of the server, so that the server can rapidly issue the corresponding files in response to a download request of a user.

4) in step S550, the file index information of the common file is read, the common file meta information is constructed, the corresponding differential file is read, the target file meta information shown in table 1 is constructed according to the common file meta information, and the target file index is updated.
The server caches corresponding meta information, reads corresponding file content according to the file range of the HTTP request, and returns the content: and reading the content of the public file for the interval of the public file, and reading the content of the differentiated file for the interval of the differentiated file. Thus, the target file is distributed and downloaded.
When the corresponding target file meta information is found in step S510, step S560 is performed, and in step S560, the server obtains the start position and the end position of the location Range (Range) requested to be downloaded by the HTTP request from the client. Subsequently, in step S570, the component position information of the common file and the differentiated file included in the target file is determined according to the target file meta information, and the common file and/or the differentiated file where the block data requested to be downloaded by the block downloading request is located is determined according to the component position information and the position range requested to be downloaded by the block downloading request of the client, the corresponding common content is read in the common file interval, the corresponding differentiated content is read in the differentiated file interval, and the read content is delivered to the client of the user. Thus, the target file is distributed and downloaded.
With the "guest letter: the APP is 1.2GB, and if the background system has 200 channels and 10 advertisement identifiers, the installation packages corresponding to different channels and advertisement identifiers are different. During the test, an iPhone terminal is used for testing. Compared with other schemes, the scheme for distributing or downloading the target file has the following value:
1. in the aspect of system storage space, for the same application, the scheme only needs to store one public part of the application file and 200 × 10 differentiated files, 1999 public part storage (1999 × 1.2GB) is saved, and the use of the storage space can be greatly reduced.
2. In the background service process, the background system provides a streaming downloading pipeline, so that the use of a memory is greatly saved, and the server resources are saved.
3. In the aspects of client consumption and user experience, the client using the method only needs to download the corresponding application installation file according to the parameters for installation.
