Description

Technical Field

[0001] This invention relates to the field of file sharing, and more particularly to file sharing methods and systems based on container virtualization technology. Background Technology

[0002] File-sharing technologies typically utilize local servers as file-sharing sources. These servers contain shared spaces for different file types, and users simply log in to the corresponding shared space to download the desired files. However, files with specific formats in the shared space require dedicated programs for decoding. Users may not have the matching programs installed, leading to the inability to open downloaded files and reducing the applicability to sharing different file formats. While users can download a matching decoding program after the file is downloaded, this increases the cost and time involved in the file-sharing process, failing to provide a reliable and convenient file-sharing and decoding solution. Summary of the Invention

[0003] The purpose of this invention is to provide a file sharing method and system based on container virtualization technology. This method divides the resources of a local server into resource sets corresponding to different groups, and constructs virtual servers that match the storage areas of the resource sets. Container virtualization technology is used to virtually expand the storage areas of the local server, enabling direct file sharing between the virtual servers and user clients. When a user client obtains an image package from the virtual server's image repository, it uses the decoder contained in the image package to directly decode the image file resources at the virtual server level, thereby achieving direct decoding and reading of the image file resources. This eliminates the need for the user client to download an additional decoder to decode the shared file resources, reducing file sharing costs and time for the user client and providing a reliable and convenient file sharing and decoding solution.

It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0059] Please see Figure 1 As shown, an embodiment of this application provides a file sharing method based on container virtualization technology, which includes:

[0060] Based on the resource storage information of the local server, the resources of the local server are divided into resource sets corresponding to different groups;

[0061] Based on the storage space change information of the local server, construct a virtual server that matches the storage range where the resource set of the corresponding group is located;

[0062] Based on the file resource type information of the storage range, a mirror file resource corresponding to the file resource stored in the storage range is generated for the virtual server;

[0063] Based on the resource acquisition request from the user, locate the image file resource that the user needs from the virtual server;

[0064] The located image file resources are packaged with the matching decoder to form an image package, and then published to the image repository corresponding to the virtual server.

[0065] After authenticating the user's client, the image package is downloaded to the user's client, and the storage status of the downloaded image package in the image repository is changed.

[0066] The beneficial effects of the above embodiments are that the file sharing method based on container virtualization technology divides the resources of the local server into resource sets corresponding to different groups, and constructs virtual servers that match the storage range where the resource sets are located. Container virtualization technology is used to virtually expand the storage range of the local server, enabling the virtual servers to directly share files with the user. When the user obtains an image package from the image repository of the virtual server, it uses the decoder contained in the image package to directly decode the image file resources contained in the image package at the virtual server level, thereby achieving direct decoding and reading of the image file resources. This eliminates the need for the user to download an additional decoder to decode the shared file resources, reducing the file sharing cost and time for the user, and providing a reliable and convenient file sharing and decoding solution for the user.

[0067] In another embodiment, based on the resource storage information of the local server, the resources of the local server are divided into resource sets corresponding to different groups, including:

[0068] Based on the resource storage information directory of the local server, obtain the file resource types stored on the local server;

[0069] Based on the file resource type, all file resources stored on the local server are divided into different resource sets; each resource set corresponds to a single file resource type, and the total data volume of file resources in each resource set is dynamically identified.

[0070] Based on the storage space change information of the local server, construct virtual servers that match the storage range of the resource set in the corresponding group, including:

[0071] Based on the results of dynamic identification, the rate at which the available storage space of the storage interval used to store each resource set on the local server decreases is obtained; if the rate at which the available storage space decreases is greater than or equal to a preset speed threshold, a virtual server matching the storage interval of the resource set in the corresponding group is constructed.

[0072] The beneficial effects of the above embodiments are that the local server (i.e., the physical server) internally stores file resources of different types and formats, and the local server forms a resource storage information directory. This resource storage information directory includes the type and format corresponding to each file resource currently stored on the local server, the file creation time, file name, and file size, and other related information. By analyzing the resource storage information directory, the format types of all file resources stored on the local server are obtained. Then, based on the file resource format types, all file resources stored on the local server are divided into different groups of resource sets, thereby distinguishing the type and format of all file resources, which facilitates the centralized processing of file resources of the same type and format in the future. Furthermore, during operation, the local server continuously receives file resources from the outside world, which increases the total data volume of each resource set. Consequently, the available storage space of the storage area on the local server where the resource set is located continuously decreases (i.e., the remaining storage space continuously decreases). The rate at which the available storage space decreases is then compared with a preset speed threshold. When the rate at which the available storage space decreases is greater than or equal to the preset speed threshold, it indicates that the available storage space of the storage area is decreasing rapidly. At this time, the local server cannot provide enough storage space for the file resources. Therefore, a virtual server matching the storage area of ​​the corresponding resource set is constructed. The corresponding storage area is expanded with the help of the virtual server, which facilitates file sharing, downloading, decoding, and viewing at the virtual server level.

[0073] In another embodiment, based on the file resource type information of the storage range, a mirror file resource corresponding to the file resources stored in the storage range is generated for the virtual server, including:

[0074] Based on the file resource type information of the storage area, obtain the matching decoder from the local server;

[0075] After mirroring all file resources and decoders in the storage area, the images are uploaded to the virtual server to form image file resources; and the image file resources are sorted according to their data size.

[0076] Based on the resource retrieval request from the user, locate the image file resource that the user needs from the virtual server, including:

[0077] The resource acquisition request from the user is parsed and processed to obtain the name of the file resource that the user needs; based on the file resource name and the mapping information of the image file resource storage location of the virtual server, the storage path of the image file resource corresponding to the file resource that the user needs is determined on the virtual server.

[0078] The beneficial effects of the above embodiments are that different types of file resources require specific decoders to be converted into viewable and editable file formats. However, not all user terminals have the corresponding decoding programs installed to process file resources. In this case, based on the file resource format type information of the storage area, a matching decoder is obtained from the local server. All file resources and decoders in the storage area are then mirrored and uploaded to the virtual server to form a mirror file resource. When the user terminal shares and downloads files with the virtual server, it can obtain the corresponding decoder simultaneously, without spending extra time searching for and downloading the decoder, thus improving the convenience of file resource decoding for the user terminal. Furthermore, the resource acquisition request from the user terminal is parsed to determine the storage path of the mirror file resource corresponding to the file resource the user terminal needs on the virtual server. This allows the user terminal to quickly and accurately find the corresponding mirror file resource on the virtual server based on the storage path.

[0079] In another embodiment, the located image file resources are packaged with a matching decoder to form an image package, and then published to the image repository corresponding to the virtual server, including:

[0080] Based on the data structure of the located image file resources, a matching packaging and compression mode is selected to package the located image file resources with the matching decoder to form an image package.

[0081] Publish the image package to the image repository corresponding to the virtual server, and send the address information of the image package in the image repository to the client;

[0082] After authenticating the user's client, the image package is downloaded to the user's client, and the storage status of the downloaded image package in the image repository is changed, including:

[0083] The system authenticates image package download requests from users. Once authentication is successful, it establishes a download channel from the user to the image repository, thereby downloading the image package to the user.

[0084] Once the user has finished downloading the image package, the image package will be deleted from the image repository.

[0085] The beneficial effects of the above embodiments are that different image file resources have different data structures (such as the data code format and code arrangement of file resources). Based on the data structure of the image file resources, the image file resources and decoder are packaged using a suitable matching compression mode, effectively avoiding compression distortion or damage to the image file resources and decoder. The image package is then published to the image repository corresponding to the virtual server, and the address information of the image package in the image repository is sent to the user client. After successful authentication, the user client can establish a dedicated download channel to the image repository. Once the user client has completed downloading the image package, using the virtual server as the file resource operating space, the downloaded decoder is directly used to decode the downloaded image file resources, allowing the user client to browse and view the file resources. Simultaneously, after the user client completes downloading the image package, it is deleted from the image repository, effectively reducing the workload of the image repository.

[0086] Please see Figure 2 As shown, an embodiment of this application provides a file sharing system based on container virtualization technology, including:

[0087] The resource classification module divides the local server's resources into different groups based on the local server's resource storage information.
