Detailed Description

The invention is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting thereof. It should be further noted that, for convenience of description, only some, but not all of the structures related to the present invention are shown in the drawings.

Example 1

Fig. 1 is a flow chart of a file sharing method based on a network disk according to a first embodiment of the present invention. The embodiment is applicable to the sharing operation of the files in the network disk, and specifically comprises the following steps:

step 101, receiving a selection operation of a file and file content in a network disk, and acquiring file ID information of the file selected by the selection operation and file ID information of the file to which the file content selected by the selection operation belongs.

The storage principle of the network disk is that the network company divides a part of capacity in a hard disk or a hard disk array of a server to registered users for use, and the file storage still needs to use disk resources, and the principle is that information in a logic file is stored in a physical disk block. The existing modes of storing files in physical disk blocks include a continuous file storage mode, a serial file storage mode, an index file storage mode and the like, and in order to realize file searching, specific file ID information (also called meta information or metadata) is needed when each file is stored, such as inode number, file size, access authority, creation time, modification time, data position on a disk and the like.

Since a large number of files may be stored simultaneously inside the net tray. Therefore, before sharing operation, the network disk user needs to select the file or the file content, and select the file or the file content to be shared. The file ID information of the selected file and the file ID information of the file to which the file content belongs in the selected operation are obtained, so that the file and the file content can be directly positioned in the storage position, further the file and the file content can be read, data support is provided for subsequent file and file content sharing, and subsequent file integration or sharing work is facilitated.

Step 102, determining the number of files to be shared according to the file ID information of the file selected by the selected operation and the file ID information of the file to which the file content selected by the selected operation belongs, and determining a file content integration rule according to the number of files to be shared.

Because a large number of files are stored in the network disk, when the network disk user performs file and file content sharing, the network disk user may select a plurality of files and file contents to share simultaneously, or may individually select a certain file or file content to share individually. Therefore, aiming at different selected operations of the network disk users, different file content integration rules need to be determined to integrate the files and the file contents in a targeted manner, so that the complexity in the sharing process is reduced, and the sharing efficiency of the files and the file contents is improved.

In order to meet the requirement of network disk users for sharing files, complicated operations and information redundancy during sharing of a plurality of files or file contents are reduced. The file sharing method based on the network disk can comprise a plurality of file content integration rules, and is used for integrating single file, single file part content, a plurality of files and a plurality of file contents, so that the subsequent sharing of single file content, multiple files or multiple file contents is conveniently realized, the operation difficulty of file sharing is reduced, redundant information in the file sharing process is reduced, and the efficiency and convenience of file sharing are improved.

Step 103, obtaining content offset information corresponding to the content of the file selected by the selected operation.

The offset is the number of bytes moved forward or backward from the specified location, and is used when finding the data used from the file. The offset is typically three, one is to move several bytes back from the beginning of the file to find the target (this is unsigned, since there is no data in front of the beginning). The second is to move several bytes forward from the end of the file to find the target (again without a sign). The third is the relative position, which is a forward or backward movement seek (signed) from the current position of the file.

Since the file is a sequence of bits, bytes, rows or records, and stored in a file block. So when the content in the file is selected, in practice the user of the disk will typically select a byte sequence. By acquiring the start and end positions (i.e., the offset) of the selected byte sequence, the file block corresponding to the selected file content and the address in the file block where the file block is located can be obtained.

Step 104, obtaining a data block stream corresponding to the selected file according to the file ID information of the selected file, and obtaining a data block stream corresponding to the selected file according to the file ID information of the file to which the selected file content belongs and the content offset information corresponding to the selected file.

Since the file is a named combination of related information recorded on the external memory. From the perspective of a disk user, a file is the smallest allocation unit of logical memory, that is, data can only be written to memory by the file. In general, files represent programs (source and target forms) and data. The data file may be digital, alphanumeric, or binary. The file may be free form, such as a text file, or may be in a strict format. Further, a file is typically a sequence of bits, bytes, rows, or records, the meaning of which is defined by the creator of the file and the network disk user, and stored in file blocks. Therefore, when the file or the file content is selected for sharing, the file block of the selected file can be acquired for subsequent integration or sharing operation.

After determining the file content integration rule, the file or the file content needs to be integrated according to the file content integration rule, so that the subsequent sharing operation is facilitated. In order to facilitate integration of files or file contents, metadata of the files and/or file contents can be directly acquired, and a data block stream is obtained.

In the practical application process, files with the same attribute can use a unified data block stream. By acquiring the unified data block stream, the subsequent data block streams can be spliced conveniently, so that a plurality of data block streams can be spliced to form a new file block stream, and the subsequent sharing operation of the file block stream is facilitated.

Optionally, the attributes described in this embodiment include, but are not limited to, one or more of the following: (1) name: the symbolic filename is unique information that is stored in human-readable form. (2) an identifier: such a unique tag (typically a number) identifies the file of the file system, which is the non-human readable name of the file. Type (3): systems supporting different types of files need this information. (4) position: the information is a pointer to the device and the location of the file on the device. (5) size: the attributes include the current size (in bytes, words, or blocks) of the file, and possibly the maximum size allowed. (6) protection: the access control information determines who can read, write, execute, etc. (7) time, date and user identification: the relevant information for file creation, last modification and last use may be saved.

Alternatively, the data block stream described in this embodiment may be one or both of a character stream and a byte stream. Where the byte stream processing unit is 1byte (byte), the operation bytes and byte array, the binary file is stored, and if the shared file is an audio file, picture, song, etc., the file block stream may be a preferred byte stream (1 byte=8 bits). The unit of character stream processing is a Unicode character of 2 bytes, and the character stream is formed by converting bytes into characters of a unit of Unicode character of 2 bytes by a Java virtual machine, and the character stream can be optimized (1 unicode=2 bytes=16 bits) if the shared file is related to Chinese or text. And a person skilled in the art can select other suitable data block streams according to the attribute of the actual file, so that when the file or the content of the file is shared, the multiple data block streams can be conveniently combined and integrated.

And 105, integrating the data block stream corresponding to the file selected by the selected operation and the data block stream corresponding to the file content selected by the selected operation according to the file content integration rule to generate a file block stream.

In order to facilitate file sharing, operation steps of multi-file sharing are reduced, and redundancy of shared information is reduced. In practical application, after determining the file content integration rule, the file content integration rule is utilized to integrate the files or the file contents in the network disk, so that the data block streams corresponding to the files or the file contents are integrated to generate new file block streams for sharing.

For example, when a network disk user needs to select and share a file and file content of a word document in the network disk, metadata of the word document can be obtained, and a data block stream is formed. The unified data block stream is the character stream, so that character streams of a plurality of word documents can be conveniently spliced, and the character streams are used for being integrated to form a continuous file block stream, so that the file block stream can be conveniently shared subsequently, and a shared user can conveniently read data in the file blocks according to the file block stream. Other attribute files are similar, and can be selected according to actual needs by those skilled in the art, and are not described herein. By integrating the data block streams of the same attribute files to form a new file block stream, the shared user can directly read word document content stored in the network disk through the integrated file block stream, so that redundant information can be effectively reduced, and file sharing efficiency is improved.

And 106, receiving sharing operation of the network disk user, and sharing the file block stream according to the sharing operation.

The network disk user can share the newly generated file block stream to other network disk users through the Internet under the existing file sharing mechanism. For example, the newly generated file block stream may be sent to other network disk users by generating links, two-dimensional codes, and the like. Compared with the sharing of original files, the file block stream integrated by the file content integration rule contains metadata of all the shared files, and the shared network disk user can also directly read the file data stored in the network disk and check the corresponding shared content through the file block stream, so that the corresponding files do not need to be searched independently, and the review difficulty of the shared network disk user is reduced.

Compared with the prior art, the method and the device can determine the number of the files to be shared according to the file ID information of the files selected by the selecting operation and the file ID information of the files to which the file contents belong, and determine the file content integration rule according to the number of the files to be shared. And obtaining a data block stream corresponding to the selected file according to the file ID information of the selected file, and further obtaining the data block stream corresponding to the selected file according to the file ID information of the file to which the selected file content belongs and the content offset information corresponding to the selected file. And finally, integrating the data block streams according to the file content integration rule to generate a file block stream for sharing, thereby reducing the complexity of the sharing operation of the file and improving the convenience of file sharing.

Example two

Fig. 2 is a flow chart of a file sharing method based on a network disk according to a second embodiment of the present invention. The present embodiment optimizes the content offset information corresponding to the content of the file selected by the selected operation based on the above embodiment, and in this embodiment, specifically optimizes the content offset information to be: acquiring the sequence of the file contents selected by the selected operation, and acquiring corresponding content offset information; according to the content offset information, acquiring a file block in which the content of the selected file is located and an address in the file block in which the content of the selected file is located; generating a shared content sequence from the file block where the file content selected by the selected operation is located and the address in the file block where the file content is located according to the sequence; and writing the sharing content sequence into metadata of the file to which the selected file content belongs according to the file ID information of the file to which the selected file content belongs, and adding sharing loading attributes for the sharing content sequence in the metadata of the file.

Correspondingly, the file sharing method based on the network disk provided by the embodiment specifically includes:

step 201, receiving a selection operation of a file and a file content in a network disk, and obtaining file ID information of the file selected by the selection operation and file ID information of the file to which the file content selected by the selection operation belongs.

Step 202, determining the number of files to be shared according to the file ID information of the file selected by the selected operation and the file ID information of the file to which the file content selected by the selected operation belongs, and determining a file content integration rule according to the number of files to be shared.

Step 203, acquiring the sequence of the file contents selected by the selected operation, and acquiring corresponding content offset information.

Since the user selects the file contents when performing the selection operation, a plurality of partial contents of a single file or partial file contents of a plurality of files may be selected. In order to obtain the content offset information corresponding to the part of file content so as to facilitate subsequent file content sharing, the content offset information corresponding to the selected file content can be obtained one by one according to the sequence of the file content selected by the user selection operation, so that the content offset information of all the file content to be shared is obtained.

In the practical application process, if a user selects the content of a file for sharing, the user needs to open the file first and then can select the content in the file, and in a single file, the user can finish the selection of the content to be shared in the file with high probability. Therefore, by acquiring the sequence of the file contents selected by the selected operation and acquiring the corresponding content offset information according to the sequence of the file contents selected by the user selected operation, not only can the acquisition of the content offset information corresponding to the contents in a plurality of files be realized, but also the acquisition of the content offset information corresponding to the contents selected in a single file is more convenient, and the acquisition difficulty of the content offset information is reduced.

Step 204, according to the content offset information, obtaining the file block where the content of the selected file is located and the address in the file block where the content of the selected file is located.

For files or programs that require efficient, fast, and reliable data access, developers prefer to use data block (also called file block) storage. Data block storage is a technique for controlling data storage and memory devices. It will take any data (such as a file or database entry) and then divide it into equal sized data blocks. The data block storage system then stores the data blocks on the underlying physical storage in a manner optimized for quick access and retrieval.

When the file content is selected by the user through the selecting operation, the data block of the file corresponding to the file content is actually required to be obtained according to the file ID information, and then the specific data block corresponding to the selected file content in the file data block and the data position (i.e. address) in the data block can be obtained according to the content offset information.

Step 205, generating a shared content sequence from the file block where the file content is selected in the selected operation and the address in the file block where the file content is selected according to the sequence.

Because the sharing of the whole file in the network disk can be realized by acquiring the metadata of the file and sending the metadata of the file to other network disk users as index links, the other network disk users can obtain the file blocks corresponding to the file through the metadata of the file, and the file content of the whole file is obtained.

Aiming at the file content selected by the user, address information needs to be added for the selected file content due to lack of the file blocks and address information in the file blocks, so that the subsequent network disk user can directly obtain the file blocks of the file content according to the address information, and further obtain the file content in the file blocks.

For example, the file block where the file content is selected in the selecting operation and the address in the file block where the file content is selected may be generated into a shared content sequence, where the shared content sequence may be a byte identical to the metadata of the file to which the corresponding file content belongs, so as to facilitate writing the shared content sequence into the metadata of the file.

Step 206, writing the shared content sequence into metadata of the file to which the selected file content belongs according to the file ID information of the file to which the selected file content belongs, and adding a shared loading attribute to the shared content sequence in the metadata of the file.

In the actual application process, for the file content selected by each selected operation, the file ID information of the file to which the file content selected by the selected operation belongs can be obtained first, then the shared content sequence corresponding to the file content is written into the metadata of the file to which the shared content sequence belongs, and the shared loading attribute is added for the shared content sequence in the metadata of the file.

For file contents in a single file, the sequence selected by a user may be different from the sequence of the file contents in the file, so that the problem of confusion of the single file contents in the subsequent sharing and loading process may be caused. Therefore, in order to facilitate the subsequent shared users to view the file content more conveniently and clearly, a sharing loading attribute can be added to the sharing content sequence in the metadata of the file, so that a plurality of file contents shared in a single file can be loaded according to the original content sequence of the file in the subsequent loading process, and the shared users can view the file.

For example, the shared loading attribute may be loaded according to the order of the file blocks corresponding to the shared content sequence in the file blocks corresponding to the belonging files. Since the file contents in the file are sequentially stored in the file blocks, the display of the file contents is facilitated. Therefore, when the file metadata is written in the shared content sequences corresponding to the file contents in the single file, the sharing loading attribute can be added to the shared content sequences. When the shared user obtains the file content through the file metadata, the file blocks corresponding to the file content can be loaded according to the sharing loading attribute, so that a plurality of file contents in the shared file are obtained, and the arrangement sequence of the file contents is the same as the original sequence.

Step 207, obtaining a data block stream corresponding to the selected file according to the file ID information of the selected file, and obtaining a data block stream corresponding to the selected file according to the file ID information of the file to which the selected file content belongs and the content offset information corresponding to the selected file.

And step 208, integrating the data block stream corresponding to the file selected by the selected operation and the data block stream corresponding to the file content selected by the selected operation according to the file content integration rule to generate a file block stream.

And 209, receiving a sharing operation of the network disk user, and sharing the file block stream according to the sharing operation.

The embodiment is specifically optimized by acquiring the content offset information corresponding to the content of the file selected by the selected operation: acquiring the sequence of the file contents selected by the selected operation, and acquiring corresponding content offset information; according to the content offset information, acquiring a file block in which the content of the selected file is located and an address in the file block in which the content of the selected file is located; generating a shared content sequence from the file block where the file content selected by the selected operation is located and the address in the file block where the file content is located according to the sequence; and writing the sharing content sequence into metadata of the file to which the selected file content belongs according to the file ID information of the file to which the selected file content belongs, and adding sharing loading attributes for the sharing content sequence in the metadata of the file.

Through the steps, not only can the content offset information corresponding to the content of the selected file be obtained, but also the file block corresponding to the content of the selected file and the address in the file block are obtained. And the shared content sequence is generated by the file block where the selected file content is located and the address in the file block where the file content is located, and the shared content sequence is written into the metadata of the file where the file content is located, so that the subsequent shared user can directly acquire the file block corresponding to the file content and the address in the file block where the file content is located through the shared content sequence in the metadata of the file, further the shared file content is more conveniently and rapidly obtained, the direct sharing and acquisition of local content of the file are realized, and the improvement of the sharing efficiency and the sharing effect of the file are facilitated.

In addition, according to the embodiment, the sharing loading attribute is added for the sharing content sequence, when the shared user obtains the file content through the file metadata, the file block corresponding to the file content can be loaded according to the sharing loading attribute, so that a plurality of file contents in the shared file are obtained, the arrangement sequence of the file contents is the same as the original sequence, the shared user can more conveniently and clearly check the file contents, and the reading difficulty of the shared user is reduced.

Example III

Fig. 3 is a flow chart of a file sharing method based on a network disk according to a third embodiment of the present invention.

In this embodiment, the number of files to be shared is determined according to the file ID information of the file selected by the selecting operation and the file ID information of the file to which the file content belongs, and the file content integration rule is determined according to the number of files to be shared, which is specifically optimized as follows: obtaining the number of the files corresponding to the content of the selected file and the comparison result of the number of the files selected by the selected operation according to the file ID information of the selected file by the selected operation and the file ID information of the file to which the content of the selected file belongs; determining the number of files to be shared according to the number of files corresponding to the content of the selected files in the selected operation and the comparison result of the number of the files selected in the selected operation; and determining a file content integration rule according to the number of the files to be shared.

step 301, receiving a selection operation of a file and a file content in a network disk, and obtaining file ID information of the file selected by the selection operation and file ID information of the file to which the file content selected by the selection operation belongs.

Step 302, obtaining the number of the files corresponding to the content of the selected file and the comparison result of the number of the files selected by the selected operation according to the file ID information of the selected file and the file ID information of the file to which the content of the selected file belongs.

Because a large number of files may exist in the network disk at the same time, and when the network disk user selects a file, the network disk user does not have to select the whole file, and may also select part of the content in a single file. Therefore, only the selected operation of receiving the files and the file contents may cause the situation that the number of the selected files is not matched with the number of the files corresponding to the selected file contents, so that further judgment on the number of the files to be shared is needed.

Illustratively, the network disk user has selected only a portion of the content in a single file, and has not selected any files. At this time, the number of files to be shared is zero, but in practice, the data block streams corresponding to part of the content in the single file still need to be integrated according to the file content integration rule corresponding to the selected single file. Therefore, it is necessary to judge this situation, so as to improve the accuracy of file content integration.

Similarly, when the network disk user selects a plurality of partial contents in a single file and does not select any file, the data block streams corresponding to the partial contents in the single file still need to be integrated according to the file content integration rule corresponding to the selected single file.

Otherwise, when the network disk user selects part of the content in the plurality of files and does not select any file, the data block streams corresponding to the part of the content in the plurality of files are integrated according to the file content integration rule corresponding to the plurality of files.

The file ID information is used as the unique identification information of the file, and the file ID information of the file is identical with the file content of the same file. Therefore, the number of the actual files to be shared can be obtained by comparing the file ID information of the files with the file content.

Step 303, determining the number of files to be shared according to the number of files corresponding to the content of the selected file in the selected operation and the comparison result of the number of files selected in the selected operation.

By acquiring the file ID information of the selected file and the file to which the content of the selected file belongs, information such as the inode number, the file size, the access authority, the creation time, the modification time, the position of the data on the disk and the like of the file can be obtained.

By matching and matching file ID information of the file to which the selected file content belongs, the file content with the same file ID information can be used as a file to be shared, and the files with the same file ID information are the same. Therefore, the repeated selected file content or files can be eliminated, and the number of files to be shared actually in the file content actually selected is further obtained and is used for determining file content integration rules subsequently.

In the actual application process, if a plurality of contents of a single file are selected, but no file is selected. At this time, by acquiring the file ID information and comparing, a plurality of contents all belong to the same file, and then the data block streams corresponding to part of the contents in the single file can be integrated according to the file content integration rule corresponding to the selected single file.

Otherwise, if the plurality of file contents and the plurality of files are selected, the part of file contents belong to the same file by acquiring the file ID information and comparing, and then the number of the files actually corresponding to the selected plurality of file contents can be obtained, and at the moment, the data block streams corresponding to the part of contents in the plurality of files are required to be integrated according to the file content integration rule corresponding to the plurality of files. Similarly, by acquiring the file ID information and comparing, the condition that the file content and the file to which the file content belongs are repeatedly selected can be obtained, so that the data block stream corresponding to the repeated file content can be conveniently processed by the subsequent file content integration rule, and repeated acquisition or integration of the data block stream with the repeated content is avoided.

And 304, determining a file content integration rule according to the number of the files to be shared.

The number of the files to be shared truly by the network disk user can be obtained by comparing the corresponding files of the selected file content with the actual number of the selected files, and the method is further used for determining the integration rule of the file content.

In this embodiment, when a plurality of files and a plurality of contents are selected, the number of files to be shared actually is obtained by obtaining and comparing the file ID information, and after determining the file content integration rule, the data block stream corresponding to the repeatedly selected file content can be removed by using the file content integration rule, so that the file information redundancy is reduced, and the integration and sharing efficiency of the data block stream is further improved.

Specifically, when the network disk user selects the file content to be shared, the file needs to be previewed or opened first, and then the content in the file is selected. After the network disk user selects part of the content of the file, the file is possibly selected again due to the preview condition and the actual need, and the whole file is shared. At this time, the file and the content thereof which are repeatedly selected can be obtained by acquiring the file ID information of the file corresponding to the content of the selected file and comparing the file ID information with the file ID information of the selected file, and then the data block stream corresponding to the content of the repeatedly selected file can be processed through the file content integration rule.

For example, when the whole file and part of the content thereof are repeatedly selected, only the data block stream corresponding to the whole file is acquired, so that repeated acquisition of the content in the same file is avoided. Similarly, when the same file content is selected for multiple times, the data block stream corresponding to the file content is only acquired once, and the data block stream of the file content is not repeatedly acquired, so that the redundancy of file information is further reduced, and repeated integration and sharing of the file content are avoided.

Step 305, obtaining content offset information corresponding to the content of the file selected by the selected operation.

Step 306, obtaining a data block stream corresponding to the selected file according to the file ID information of the selected file, and obtaining a data block stream corresponding to the selected file according to the file ID information of the file to which the selected file content belongs and the content offset information corresponding to the selected file.

Step 207, integrating the data block stream corresponding to the file selected by the selected operation and the data block stream corresponding to the file content selected by the selected operation according to the file content integration rule, so as to generate a file block stream.

And 308, receiving sharing operation of the network disk user, and sharing the file block stream according to the sharing operation.

In this embodiment, the number of files to be shared is determined by using the file ID information of the file selected according to the selected operation and the file ID information of the file to which the content of the file selected by the selected operation belongs, and the file content integration rule is determined according to the number of files to be shared, which is specifically optimized as follows: obtaining the number of the files corresponding to the content of the selected file and the comparison result of the number of the files selected by the selected operation according to the file ID information of the selected file by the selected operation and the file ID information of the file to which the content of the selected file belongs; determining the number of files to be shared according to the number of files corresponding to the content of the selected files in the selected operation and the comparison result of the number of the files selected in the selected operation; and determining a file content integration rule according to the number of the files to be shared.

Through the steps, the number of the files actually corresponding to the file contents to be shared can be determined, so that the corresponding file content integration rule is determined to integrate the data block streams corresponding to the file contents. And meanwhile, the file and the content thereof which are repeatedly selected can be obtained by acquiring and comparing the file ID information of the file to which the content of the selected file belongs and the file ID information of the selected file, so that the repeated acquisition of the data block stream corresponding to the same file content during the subsequent acquisition of the data block stream is avoided, the redundancy of the file information is further reduced, and the repeated sharing and integration of the file content are avoided.

Example IV

Fig. 4 is a flow chart of a file sharing method based on a network disk according to a fourth embodiment of the present invention. In this embodiment, the number of files to be shared is determined according to the comparison result of the number of files corresponding to the content of the selected file according to the selected operation and the number of files selected by the selected operation, and the following steps are added: and when the number of the files corresponding to the file content selected by the selected operation is inconsistent with the number of the files selected by the selected operation, taking the number of the files corresponding to the file content selected by the selected operation as the number of the files to be shared.

step 401, receiving a selection operation of a file and a file content in a network disk, and obtaining file ID information of the file selected by the selection operation and file ID information of the file to which the file content selected by the selection operation belongs.

Step 402, obtaining the number of files corresponding to the content of the selected file and the comparison result of the number of files selected by the selected operation according to the file ID information of the selected file and the file ID information of the file to which the content of the selected file belongs.

Step 403, determining the number of files to be shared according to the number of files corresponding to the content of the selected file in the selected operation and the comparison result of the number of files selected in the selected operation.

And 404, when the number of files corresponding to the file content selected by the selected operation is inconsistent with the number of files selected by the selected operation, taking the number of files corresponding to the file content selected by the selected operation as the number of files to be shared.

After the network disk user selects the file, the content of the selected file is equal to the whole content of the selected file, so that the content of the selected file cannot be zero, and if the content of the selected file is zero, the network disk user does not perform the selection or sharing operation. The network disk user may select part of the content of the file in the actual operation process, but does not select any file, at this time, the number of the selected files is zero, but the number of the actually selected files cannot be processed according to zero, and still the content of the files needs to be integrated and shared; therefore, whether the network disk user selects part of the content of the file needs to be judged later, and the number of the files actually selected by the network disk user is further obtained, so that the data block streams corresponding to the file content can be integrated conveniently later according to the file content integration rule.

For example, if the number of files corresponding to the content of the selected file is zero and the number of the selected files is one, it is indicated that the network disk user only selects the files, and the data block streams of the files need to be integrated according to the file content integration rule corresponding to the selected single file. Otherwise, if the number of files corresponding to the selected file content is one and the number of the selected files is zero, the network disk user only selects part of the content in the single file to share, and still needs to integrate the data block streams corresponding to the part of the content in the single file according to the file content integration rule corresponding to the selected single file.

And similarly, if the number of the selected files or the number of the files corresponding to the content of the selected files is larger than one, the network disk user is informed of selecting the content of the plurality of files for sharing, and the data block streams corresponding to part of the content in the plurality of files are integrated according to the file content integration rule corresponding to the plurality of files.

In the actual application process, when the number of files corresponding to the selected file content is different from the number of the selected files, this means that the network disk user selects the content in other files in addition to the files with the corresponding number, so that the data block streams corresponding to part of the content in the files need to be integrated according to the file content integration rules corresponding to the files. At this time, if the number of files corresponding to the content of the file selected by the selected operation is greater than the number of files selected by the selected operation, in order to ensure the accuracy of integrating the content of the subsequent file, the number of files corresponding to the content of the file selected by the selected operation needs to be used as the number of files to be shared.

Step 405, determining a file content integration rule according to the number of the files to be shared.

Step 406, obtaining content offset information corresponding to the content of the file selected by the selected operation.

Step 407, obtaining a data block stream corresponding to the selected file according to the file ID information of the selected file, and obtaining a data block stream corresponding to the selected file according to the file ID information of the file to which the selected file content belongs and the content offset information corresponding to the selected file.

By combining the processing manner when the file and the file content are repeated in the second embodiment, if the whole file and part of the content thereof are selected, only the data block stream corresponding to the whole file can be obtained, and the data block stream of the repeated file content in the file is not obtained any more, so that the repeated obtaining of the file content is avoided, the redundancy of the file information is reduced, and the integration efficiency of the subsequent data block streams is improved.

Step 408, integrating the data block stream corresponding to the file selected by the selected operation and the data block stream corresponding to the file content selected by the selected operation according to the file content integration rule, so as to generate a file block stream.

And 409, receiving a sharing operation of the network disk user, and sharing the file block stream according to the sharing operation.

According to the embodiment, the number of the files to be shared is determined through the comparison result of the number of the files corresponding to the content of the files selected according to the selected operation and the number of the files selected by the selected operation, and the following steps are added: when the number of the files corresponding to the file content selected by the selected operation is inconsistent with the number of the files selected by the selected operation, the number of the files corresponding to the file content selected by the selected operation is used as the number of the files to be shared, so that the actual number of the files to be shared by the network disk user can be obtained, and the file content integration rule can be more accurately determined.

Example five

Fig. 5 is a flow chart of a file sharing method based on a network disk according to a fifth embodiment of the present invention; the present embodiment optimizes the file content integration rule based on the above embodiment, and in this embodiment, the file content integration rule is specifically optimized as follows: and when the number of the files to be shared is single, directly generating a file block stream by using the data block stream corresponding to the file selected by the selected operation or the data block stream corresponding to the file content selected by the selected operation. And when the number of the files to be shared is multiple, merging the data block stream corresponding to the file selected by the selected operation with the data block stream corresponding to the file content selected by the selected operation according to a preset arrangement mode to generate a file block stream.

step 501, receiving a selection operation of a file and a file content in a network disk, and obtaining file ID information of the file selected by the selection operation and file ID information of the file to which the file content selected by the selection operation belongs.

Step 502, obtaining the number of files corresponding to the content of the selected file and the comparison result of the number of files selected by the selected operation according to the file ID information of the selected file and the file ID information of the file to which the content of the selected file belongs.

Step 503, determining the number of files to be shared according to the number of files corresponding to the content of the selected file and the comparison result of the number of files selected by the selected operation.

And 504, when the number of files corresponding to the file content selected by the selected operation is inconsistent with the number of files selected by the selected operation, taking the number of files corresponding to the file content selected by the selected operation as the number of files to be shared.

Step 505, determining a file content integration rule according to the number of the files to be shared.

Step 506, obtaining content offset information corresponding to the content of the file selected by the selected operation.

Step 507, obtaining a data block stream corresponding to the selected file according to the file ID information of the selected file, and obtaining a data block stream corresponding to the selected file according to the file ID information of the file to which the selected file content belongs and the content offset information corresponding to the selected file.

And step 508, integrating the data block stream corresponding to the file selected by the selected operation and the data block stream corresponding to the file content selected by the selected operation according to the file content integration rule to generate a file block stream.

Step 509, when the number of files to be shared is single, directly generating a file block stream by using the data block stream corresponding to the file selected by the selected operation or the data block stream corresponding to the content of the file selected by the selected operation.

Since the data block stream of the single file or the file content in the single file can be directly obtained without merging or combining, when the single file or the file content of the single file is selected, the metadata (i.e., the data block stream) of the single file can be directly obtained as the file block stream. For the file content of the selected single file, loading can be performed subsequently according to the shared content sequence and the corresponding shared loading attribute in the metadata, so that the shared user can view the shared file content.

Compared with the existing whole file sharing, in the actual operation process, the network disk user can share the partial content of the file to be shared to the sharee by selecting the partial content of the file to generate the file block stream, so that the redundancy of the file information is reduced, the file sharing efficiency is improved, the sharee can acquire the shared content more directly, and the convenient sharing of the file is realized.

And 510, when the number of the files to be shared is multiple, merging the data block stream corresponding to the file selected by the selected operation with the data block stream corresponding to the file content selected by the selected operation according to a preset arrangement mode to generate a file block stream.

When the number of the files to be shared is multiple, the files or the file contents in the different files are necessarily present, and after the data block streams of the corresponding files and the file contents are obtained, the data block streams need to be combined to form a whole section of data block stream, so that the new file block stream can be generated. However, the merging of the data block streams needs to be performed in a regular arrangement mode, so that file contents in the file block streams generated after merging can be arranged and displayed in a certain sequence, and the file contents are convenient for a subsequent sharee to check.

Optionally, the preset arrangement includes, but is not limited to, one or several of the following:

1. and splicing the plurality of data block streams in sequence according to the file selection order to generate a file block stream, wherein the operation of selecting the file content can be equal to the operation of selecting the file. By adopting the mode, when the network disk user shares the file, the file or the file content to be shared can be sequentially selected according to the file preview condition and the file content which the network disk user wants to view in turn, and then the acquired data block streams are sequentially spliced according to the file selection sequence, so that the merging and integration of the data block streams are realized, and further the file block streams are generated.

2. And splicing the plurality of data block streams in sequence according to the selected sequence of the folders to generate a file block stream. By adopting the preset arrangement mode, when the network disk user shares files, according to the file preview condition, the network disk user can sequentially select the folders needing to be shared according to the file content in the folders which the network disk user wants to sequentially check, determine that the subsequent data block streams are spliced according to the folder selection sequence, and then the network disk user can splice the acquired data block streams according to the folder selection sequence even if the network disk user does not select the files or the file content according to the folder selection sequence, so that the file block streams are generated.

Specifically, by adopting the preset arrangement mode, the contents in the data block streams can be integrated according to folders, and after the data block streams in each folder are spliced according to the file or file content selection sequence in the folder, the data block streams corresponding to the folders are spliced according to the folder selection sequence. And finally, segmenting or grouping the contents in the file block stream according to the folders, and arranging the contents according to the selected sequence of the folders, so that sharees can conveniently and quickly view the file contents in the same folder.

3. And splicing the plurality of data block streams in sequence according to the file attribute information arrangement order to generate a file block stream. The file attribute information includes a name, an identifier, a type, a location, a size, a modification time, and the like. For example, taking the case of splicing sequentially according to the name arrangement sequence, the file block streams can be arranged according to a file name arrangement mechanism from the Arabic letters A to Z in the prior art to obtain the file attribute information arrangement sequence of the file, and then the data block streams obtained correspondingly are spliced sequentially according to the corresponding file name arrangement mode to generate the file block streams. In the practical application process, a person skilled in the art can select other types of file attribute information and the corresponding arrangement sequence thereof according to practical needs to arrange the data block streams so as to realize that the data block streams are spliced in sequence according to the arrangement sequence of the file attribute information of the corresponding file to generate the file block streams, and further realize that the content in the file block streams can be arranged according to rules, so that the content can be conveniently checked by a subsequent sharee, and the repeated description is omitted.

In an actual use process, before a network disk user selects a file or file content, a preset arrangement mode option can be provided for the network disk user, so that the network disk user can select a proper preset arrangement mode according to actual needs, and then when a plurality of files and/or a plurality of file contents are selected, the acquired data block streams can be spliced in sequence according to the preset arrangement mode selected by the network disk user, so that a new file block stream is generated.

And step 511, receiving a sharing operation of the network disk user, and sharing the file block stream according to the sharing operation.

The embodiment specifically optimizes the file content integration rule as follows: and when the number of the files to be shared is single, directly generating a file block stream by using the data block stream corresponding to the file selected by the selected operation or the data block stream corresponding to the file content selected by the selected operation. And when the number of the files to be shared is multiple, merging the data block stream corresponding to the file selected by the selected operation with the data block stream corresponding to the file content selected by the selected operation according to a preset arrangement mode to generate a file block stream. After the plurality of file block streams are obtained, the plurality of data block streams can be combined and integrated according to a preset arrangement mode, so that the plurality of data block streams can be spliced in sequence according to the preset arrangement mode, further the file block streams are generated, the contents in the file block streams can be arranged according to a rule, the file block streams are convenient for a sharer to check, and the convenience of file sharing is further improved.
