It should be noted that, in the present application, a plurality may refer to two or more, and will not be described in detail later.

The metadata synchronization module can be used for synchronizing metadata corresponding to shared files in different devices; the metadata synchronization module and the file data transmission module are in an isolated state, that is, the transmission of data in the two modules is isolated and independent and does not affect each other. The file data transmission module is used for transmitting file contents and can comprise at least one of the following: video data, image data, text data, etc., without limitation.

The file monitoring module is configured to monitor a state of a file, for example, whether the file is modified by a file name, deleted, modified by content, and the like, which is not limited herein.

It can be seen that, in the present application, the metadata can be separated from the file data, and the transmission of the file resource is realized through the metadata, instead of transmitting all the file data to other sharing devices in a packaged manner, which is beneficial to reducing the bandwidth in network transmission. In addition, the user can set the authority of sharing the file by himself, which is beneficial to improving the information security.

In the second section, the scope of protection of the claims disclosed in the embodiments of the present application is described below.

Referring to fig. 2, fig. 2 is a flowchart illustrating a resource sharing method according to an embodiment of the present application, applied to a first device.

S201, determining a shared file and metadata corresponding to the shared file.

The shared file may be set by the user or default by the system, which is not limited herein. The shared file may refer to one or more files that are available for sharing. The shared file may indicate file resources that can be shared to other sharing devices, and may include at least one of: pictures, videos, text, etc., the first device may set the same or different shared files to different sharing devices through permission settings.

The first device and other sharing devices may be in the same local area network, and in some special scenarios, for example, when a network in the local area network is interrupted or fails, file sharing may also be implemented through a hotspot or in other manners.

Wherein the metadata may be used to include at least one of: a timestamp, a device name, a file thumbnail, etc., without limitation; the metadata may be used to characterize its corresponding shared file, or may be a characteristic or fingerprint of the shared file. The memory occupied by the metadata is far smaller than the file data corresponding to the shared file.

S202, establishing a sharing N-ary tree corresponding to the first device according to the metadata, wherein the sharing N-ary tree comprises a metadata directory and a file object.

The shared N-ary tree may be configured to manage metadata corresponding to all files in the first device, may include shared files shared to other multiple shared devices, and may include a metadata directory generated by all metadata corresponding to all shared files and a file object corresponding to each shared file. The file object may be used to locate or index to a specific file in the local database and its corresponding file content, which may be a link or file path, etc.

The shared N-ary tree can comprise a father node and a plurality of child nodes, an N-ary tree data structure can be established through metadata, and the N-ary tree data structure can be used for quickly searching and positioning file contents corresponding to the metadata.

Wherein, the first device may comprise a plurality of shared N-trees; specifically, when the first device is used as a master device (a device that sends a shared file) or a sharing device (a device that receives a shared file) for sharing a file, the corresponding sharing N-ary trees are different. When the shared N-ary tree is used as the main device, the shared N-ary tree can be generated by the first device according to the metadata corresponding to the locally stored file, and the file content can be provided for other devices through the shared N-ary tree; when the first device serves as a sharing device, the first device can receive metadata sent by other main devices, the received metadata are used for generating shared N-ary trees corresponding to the other main devices, file contents shared by the other main devices can be obtained through the shared N-ary trees, and each other main device can correspond to one shared N-ary tree.

In one possible example, the method further includes the steps of: monitoring the state condition of the shared file; and if the state information of any one of the shared files is determined to be changed, updating the shared N-ary tree according to the state information.

The shared file includes a plurality of shared files, each shared file may correspond to one piece of state information, and the state condition of the shared file may be monitored through the state information, for example: whether the shared file is deleted, whether the file name of the shared file is renamed, whether the file format of the shared file is changed, and the like, which are not limited herein.

In one possible example, the updating the shared N-ary tree according to the state information may include: positioning a target node in the shared N-ary tree corresponding to the state information; updating metadata corresponding to the target node according to the position of the target node in the shared N-ary tree; and determining target sharing equipment corresponding to the target node, and synchronizing the updated metadata to the target sharing equipment.

The metadata and the shared file are in one-to-one correspondence, when the state information of the shared file changes, a target node can be located through an inode number of the shared file, the metadata corresponding to the target node is updated according to the position of the target node in the shared N-ary tree, and then a parent node corresponding to the target node is determined, so that a target sharing device is located, the target sharing device can comprise the second device, when the target sharing device is a plurality of target sharing devices, the updated metadata can be simultaneously sent to the target sharing devices, and the updated metadata is used for the target sharing devices to update the shared N-ary tree corresponding to the first device in the own device.

Therefore, in the application, as the metadata and the shared file are in one-to-one correspondence, when the shared file changes, the metadata in other shared devices can be updated through the metadata, so that the consistency of the shared file resources in the two devices is ensured.

Optionally, when the first device is used as a master device, a user corresponding to the first device sets a modification permission of the shared file through permission setting; if other sharing devices have the authority to modify the shared file, the metadata information about the target file in the N-ary trees of the two devices (the first device and the other sharing devices) can be synchronously modified after the state information of the shared file is changed.

S203, determining a sharing range corresponding to a second device, and retrieving target metadata corresponding to the sharing range from the metadata directory, wherein the second device is any one of a plurality of sharing devices of the first device sharing files.

The sharing scope may refer to a scope stored in the user or the first device for sharing files to the second device, and may include a specific number of files, file contents, and so on.

The sharing scope corresponding to each sharing device may be the same or different, and the second device may refer to any one of a plurality of sharing devices that the first device shares the shared file.

S204, synchronizing the target metadata to the second device.

The target shared file can be determined according to the sharing range of the shared file which is set by the first device and is shared into the second device, and the corresponding target metadata and the structural relationship of the target metadata in the shared N-ary tree, namely the metadata object relationship are determined; further, the target metadata and the metadata object relationship corresponding to the target metadata can be sent to the second device together, and the target metadata can be used for the second device to construct a target sharing N-ary tree corresponding to the first device according to the metadata object relationship; the target shared N-ary tree is different from the shared N-ary tree generated by the first device. The target metadata can be used for the second device to acquire file data (file content and the like) corresponding to the target metadata in the first device.

Therefore, the metadata and the file data are separated, and only the metadata are synchronized in the synchronization process, so that the bandwidth required in network transmission is reduced, and the file is synchronized quickly.

Referring to fig. 3, fig. 3 is a flowchart illustrating a resource sharing method according to an embodiment of the present application, applied to a second device.

S301, receiving target metadata sent by the first device.

The target metadata corresponds to the second device, and may refer to metadata information corresponding to a shared file that the first device allows the second device to acquire.

After the first device sets the sharing range of the second device, the target metadata for the second device is determined, and then the second device can passively receive the target metadata sent by the first device; therefore, the method is beneficial to the user to access at any time, the first equipment does not need to be moved to obtain the target metadata, and the method is beneficial to improving the rapid synchronization of the files.

S302, generating a target sharing N-ary tree corresponding to the first device according to the target metadata, wherein the target sharing N-ary tree comprises a metadata directory and a metadata object relation corresponding to the target metadata.

The target shared N-ary tree is different from the shared N-ary tree in the first device, and the shared N-ary tree in the first device may refer to an N-ary tree generated by all metadata corresponding to the shared file that the first device allows all other shared devices to acquire. The target N-ary tree may refer to an N-ary tree corresponding to the shared file in the first device, which is obtained by the second device. When the second device is used as a sharing device, a plurality of main devices can be corresponded to, and the shared files in the plurality of main devices can be accessed and obtained, wherein the second device comprises a shared N-ary tree corresponding to each main device.

The metadata object relationship is used to indicate a relationship between parent and child nodes of a target shared file corresponding to target metadata transmitted by the first device, that is, a relationship between inode numbers.

Unlike the sharing N-ary tree in the first device, the target sharing N-ary tree only includes the metadata directory corresponding to the target metadata and the metadata object relationship between the target metadata, and the sharing N-ary tree in the embodiment shown in fig. 2 includes the file object corresponding to the shared file, that is, the file path for searching the shared file in the local database.

In the target sharing N-ary tree, the marks can be distinguished through the inode number of the file system, the device ID of the first device can be used as a parent node, and the inode number corresponding to different metadata can be used as a child node, so that the marks of the target sharing N-ary tree metadata are realized. The parent node can be found through the inode number.

And S303, displaying the target shared file corresponding to the target metadata in a preset page of the second device according to a preset rule.

The preset rules and/or the preset pages can be set by the user or defaulted by the system, and are not limited herein; the preset page may refer to a page designated in the second device for presenting the target metadata.

In a possible example, the displaying, according to the preset rule, the target shared file corresponding to the target metadata in the preset page of the second device may include the following steps: if the target metadata is used for indicating video data and/or picture data, displaying a thumbnail corresponding to the video data and/or the picture data in the preset page; and if the target metadata is used for indicating text data, displaying a cover page of the text data in the preset page.

The thumbnail and the cover page can be specified by the first device when the authority is set, and the thumbnail and/or the cover page can be used for the user to know some relevant basic information of the shared file, such as image content corresponding to image data, or writer and abstract information corresponding to text information.

Therefore, in the application, the corresponding display mode can be determined according to different file types so that the user can obtain the basic information corresponding to the shared file, and therefore the user can select the file which the user wants, user experience can be improved, and practicability of data display can be improved.

In one possible example, the method may further include the steps of: responding to the selection of the user for the thumbnail and/or the cover, and sending a file acquisition request to the first device, wherein the file acquisition request is used for acquiring file content corresponding to the target metadata; and displaying the file content in the preset page.

The user can click and select the thumbnail, the first device can determine a main device (in the embodiment of the application, the first device is defaulted to be the first device) corresponding to the thumbnail or the cover when detecting that the user clicks the thumbnail or the cover, and then the target metadata corresponding to the thumbnail or the cover is sent to the main device, and further the main device can locate a node corresponding to the target metadata in a local corresponding shared N-ary tree according to the target metadata, and then index file data such as specific file content from a local database according to a file object corresponding to the node, and send the file content to the second device, so that sharing and synchronization of file resources are completed.

Therefore, in the application, the shared N-ary tree between the two devices can be established through the metadata, and the specific main device is positioned based on the parent-child relationship in the shared N-ary tree, so that the specific file content corresponding to the target metadata in the main device is obtained, the occupied bandwidth of network transmission is reduced, the rapid synchronization of the files is favorably realized, and the user can select the obtaining mode immediately, so that the waste of the network transmission bandwidth is favorably avoided.

It can be seen that, in the resource sharing method described in the embodiment of the present application, the second device may receive the target metadata sent by the first device; generating a target sharing N-ary tree corresponding to the first device according to the target metadata, wherein the target sharing N-ary tree comprises a metadata directory and a metadata object relation corresponding to the target metadata; and displaying the target shared file corresponding to the target metadata in a preset page of the second equipment according to a preset rule. Therefore, the metadata and the file data are separated, and only the metadata are synchronized in the synchronization process, so that the bandwidth required in network transmission is reduced, and the file is synchronized quickly.
