Technical Field

The present application relates to the field of communications technologies, and in particular, to a file sharing method and apparatus, and a file synchronization system.

Background

With the development of communication technology, file synchronization systems are widely used. In the related art, a file synchronization system is composed of terminals and servers, and generally, the file synchronization system has two scenarios, namely a single server scenario and a multi-server scenario, where a plurality of terminals perform file synchronization with the same server and a plurality of terminals perform file synchronization with different servers respectively in the multi-server scenario.

The file synchronization system 0 may include multiple sets of terminals and servers for file synchronization, and there may be one or more terminals for file synchronization with each server, and fig. 1 only illustrates that the file synchronization system 0 includes two sets of terminals and servers for file synchronization, and one terminal for file synchronization with each server is taken as an example. The files in the embodiment of the invention can be as follows: text, picture, audio or video type files.

Any two devices connected as described above may be connected via a wired network or a wireless network, where the wired network may include, but is not limited to: universal Serial Bus (USB), wireless networks may include, but are not limited to: wireless Fidelity (WIFI for short), bluetooth, infrared, Zigbee, data, and the like.

Fig. 2 is a schematic structural diagram of a file sharing device according to an embodiment of the present invention, where the file sharing device may be used at a management end, a source terminal, a source server, a destination terminal, or a destination server in the file synchronization system shown in fig. 1. Referring to fig. 2, the file sharing apparatus may include a processor 201, a memory 202, a communication interface 203, and a bus 204. The processor 201, memory 202, and communication interface 203 are communicatively coupled via a bus 204.

The source terminal and the target terminal in fig. 1 respectively perform file synchronization with different servers, that is, fig. 1 shows a multi-server scenario in a file synchronization system.

Fig. 3 is a flowchart of a file sharing method according to an embodiment of the present invention, where the file sharing method may be used in the file synchronization system shown in fig. 1. It should be noted that before executing the file sharing method shown in fig. 3, the management end needs to be authenticated, which is specifically as follows:

each terminal needs to register at a server to enable the terminal to perform file synchronization with the server on which the terminal is registered, wherein the server on which the source terminal performs registration is called a source server, the server on which the target terminal performs registration is called a target server, and the source server is different from the target server. Each terminal can also be provided with a client of a management terminal, and after each terminal is provided with the client, the terminal needs to register a user account on the management terminal through the client and sign the authority granted to the client for accessing the files on the terminal. In addition, each terminal also needs to bind the registered server and user account on the client, and authorize the management terminal to access the information of the file in the server.

For example, after the terminal binds the registered server and the user account on the client, the management terminal may send an authorization request of the server to the user through the client, so as to prompt the user of the terminal to control the terminal to send an authorization permission of the server to the management terminal. Then, the management side can forward the authorization permission to the service side so as to trigger the service side to send an access token to the management side. The access token is used for the management terminal to access the information of the file in the server terminal. After obtaining the access token, the management side may call an open Application Programming Interface (API) of the server side to query information of a file in the server side by using the access token. The information of the file in the server may include: the network address of the file, such as a Uniform Resource Locator (URL). It should be noted that the access token is only used for the management end to obtain the information of the file, but not used for the management end to obtain the file itself, and the information of the file in the server may further include other information, such as attribute information of the file, and the like, which is not limited in this embodiment of the present invention.

At this time, the management side has the authority to acquire information (such as a network address) of a file in each service side and the authority to acquire information (such as attribute information and fingerprint information) of the file in each terminal through the client, and the management side stores a synchronization relationship between the terminal and the service side (the service side for indicating synchronization of each terminal). The management terminal is used for managing the information of the files in each service terminal and the information of the files in each terminal. Wherein, the attribute information may include: creation time (× year × month × day × time × minute × second), creation place (× longitude × latitude), file type (such as text type, picture type, audio type, etc.) storage address, last modification time, and the like, where "×" means "some". The fingerprint information of a certain file can be obtained by processing the file through a content-based fingerprint technology by a client, and when the contents of two files are different, the two files are different.

After the management terminal finishes authentication, any two terminals (such as a source terminal and a target terminal) which perform file synchronization with different service terminals in the file synchronization system can share files. As shown in fig. 3, the file sharing method may include:

step 301, the source terminal sends a sharing request to the target terminal.

For example, when a source user (i.e., a user of a source terminal) needs to share a file with a target user (i.e., a user of a target terminal), the source user may operate on a client of the source terminal to select target attribute information, and control the source terminal to send a sharing request to the target terminal, where the sharing request may include: an identification of the source user (e.g., identity information of the user), an identification of the source terminal (e.g., a unique identification code of the source terminal), and target attribute information. Wherein, the attribute indicated by the attribute information in the source terminal includes target attribute information, and the file having the attribute indicated by the target attribute information includes: n first files, the n first files forming a first file set, n ≧ 1, so the share request indicates: the source terminal requests to share the first file set to the target terminal.

Step 302, the target terminal sends a sharing agreement response to the source terminal.

After receiving the sharing request, the target terminal may present the sharing request to the target user. If the target user agrees to obtain the first file set which the source user wants to share, the target user can operate on the target terminal to confirm the sharing request, so that the target terminal generates a sharing agreement response aiming at the sharing request according to the sharing request and sends the sharing agreement response to the source terminal.

Step 303, the target terminal sends sharing indication information to the management terminal.

After the target user can operate on the target terminal to confirm the sharing request, the target terminal can also generate sharing indication information and send the sharing indication information to the management terminal. The sharing indication information may include: the sharing indication information is used for indicating: the method comprises the steps of obtaining a first file set to be shared by a source terminal, and taking a sharing object of the first file set as a target terminal.

And step 304, the management terminal determines a source server for performing file synchronization with the source terminal and a target server for performing file synchronization with the target terminal according to a preset synchronization relationship between the terminal and the server.

After receiving the sharing indication information sent by the target terminal, the management terminal can analyze the sharing indication information to determine a source terminal and a target terminal which need to perform file sharing, and query a preset synchronization relationship between the terminal and the server to determine a source server which performs file synchronization with the source terminal and a target server which performs file synchronization with the target terminal.

And 305, the management terminal sends an authorization code acquisition request to the source server terminal according to the sharing indication information.

The authorization code obtaining request is used for obtaining an authorization code for sharing the first file set with the target terminal, and the authorization code obtaining request may carry an identifier of the active terminal, an identifier of the source server, an identifier of the target terminal, an identifier of the target server, identity information of the target user, and target attribute information.

And step 306, the source server side obtains the request according to the authorization code and sends a verification request for sharing the first file set to the target terminal to the source terminal.

The authentication request may carry identity information of the target user and target attribute information.

And 307, the source terminal feeds back a verification success response to the source server according to the verification request.

After receiving the verification request, the source terminal may present the verification request to the source user, and the source user may verify the identity information and the target attribute information of the target user (i.e., verify an event that the target terminal shares the first file set), and after the verification is successful, control the source terminal to send a verification success response to the source server. For example, the verification request may also carry: the short message verification code, the source user confirming the verification request on the source terminal may include: the source user transmits the short message verification code back to the source server.

Step 308, the source server generates an authorization code for sharing the first file set with the target terminal.

After receiving the verification success response sent by the source terminal, the source server can determine that the event for sharing the first file set with the target terminal is correct, and generate an authorization code for sharing the first file set with the target terminal, wherein the authorization code is used for authorizing the target server to download the files in the first file set in the source server. That is, if the target server holds the authorization code, the target server may download any file in the first file set in the source server according to the authorization code. In the embodiment of the invention, the event of sharing the first file set to the target terminal is verified through the source terminal, the downloaded first file and the equipment for downloading the first file are limited through the authorization code, and the accuracy of file sharing is ensured.

Step 309, the source server sends an authorization code for sharing the first file set to the target terminal to the management terminal.

Step 310, the management terminal compares the target attribute information with the attribute information of each file in the source terminal to determine n first files in the source terminal.

After receiving the sharing indication information sent by the target terminal, the management terminal may further analyze the sharing indication information to determine target attribute information in the sharing indication information, and then may acquire attribute information of each file in the source terminal to determine n first files having an attribute indicated by the target attribute information in the source terminal.

For example, as shown in table 1, files 1, 2, 3, 4, and 5 are stored in the source terminal, the attributes indicated by the attribute information of the files 1, 2, and 3 are a and B, and the attributes indicated by the attribute information of the files 4 and 5 are B. If the attribute indicated by the target attribute information is a, the management end may determine that files 1, 2, and 3 are all first files, and the first file set includes: documents 1, 2 and 3.

TABLE 1

Document	Property indicated by property information of file
		1	A and B
2	A and B
		3	A and B
4	B
		5	B

Step 311, the management terminal compares the fingerprint information of each first file with the fingerprint information of each file in the target terminal to determine whether the target first file exists in the n first files. When the target first file exists in the n first files, execute step 312; when the target first file does not exist in the n first files, step 317 is performed.

The fingerprint information of the target first file is different from the fingerprint information of each file in the target terminal. After the management terminal determines the n first files, the fingerprint information of each first file and the fingerprint information of each file in the target terminal can be obtained. Then, the management terminal may compare the fingerprint information of each first file with the fingerprint information of each file in the target terminal to determine whether the target first file exists in the n first files.

For example, if the n first files are files 1, 2, and 3 in table 1, and the files stored in the target terminal include: documents 1, 4, 6, 7 and 8. The management terminal may determine that the files 2 and 3 are both the first target file after comparing the fingerprint information, that is, the files 2 and 3 are files that the source terminal needs to share with the target terminal, and the target terminal does not store the files 2 and 3. Therefore, the file (such as the file 1) stored in the target terminal is prevented from being shared with the target terminal, the occupation of the shared file (such as the file 1) on network resources is reduced, and the file sharing efficiency is improved.

Step 312, the management end obtains the network address of the target first file from the network address of the file in the source server end.

After determining the target first file, the management terminal may obtain the network address of the target first file in the network address of the file in the source server terminal through the open API of the source server terminal according to the access token obtained in the authentication stage.

For example, the management side may send an acquisition request to the source server side, where the acquisition request may include: the storage address of the target first file in the source terminal (attribute information belonging to the target first file), the identification of the source terminal, the identification of the source server side and the access token. Since the source server and the source terminal perform file synchronization, each file and attribute information thereof in the source terminal, and a network address of each file on the source server are stored in the source server. After receiving the obtaining request, the source server may query a network address of the target first file in the source server according to a storage address of the target first file in the source terminal, and send the network address of the target first file in the source server to the management terminal.

The open API of the server in the embodiment of the present invention may be of various types, such as: a HyperText Transfer Protocol (HTTP) type, a Java (one computer programming language) type, or a C + + (another computer programming language) type, and the like. The HTTP types may include: with either Representational State Transfer (Restful) or Simple Object Access Protocol (SOAP).

Step 313, the management end generates download instruction information, wherein the download instruction information includes: the authorization code, the identification of the source server, and the network address of the target first file.

After obtaining the authorization code for sharing the first file set with the target terminal and the network address of the target first file, the management terminal may generate download instruction information including the authorization code, the identifier of the source server, and the network address of the target first file.

And step 314, the management terminal sends downloading indication information to the target service terminal.

The management terminal can send the downloading indication information to the target server terminal by calling the open API of the target server terminal.

And 315, the target server downloads the target first file from the source server according to the downloading indication information.

After receiving the download instruction information sent by the management end, the target server may send a download request to the source server, where the download request may be an HTTP request, and the download request includes: the network address of the target first file, the authorization code, the identifier of the source server and the identifier of the target server. After receiving the download request, the source server may check information in the download request with information in the authorization code acquisition request, and after checking that the information is correct, may send the target first file to the target server.

Step 316, the target server synchronizes the target first file to the target terminal.

After acquiring the target first file, the target server may directly synchronize the target first file with the target terminal, or may send a synchronization request to the target terminal first, and synchronize the target first file with the target terminal only after the target terminal confirms the synchronization request. At this point, the target terminal acquires all the first files in the first file set.

Step 317, the management terminal forbids to instruct the target service terminal to download the files in the first file set.

If the target first file does not exist in the n first files, the management terminal can determine that all the first files are stored in the target terminal, and therefore the management terminal does not need to instruct the target server terminal to download any one first file.

In addition, after each terminal grants the client the right to access the file on the terminal, the client can also extract the fingerprint information of each file in the terminal and control the terminal to send the fingerprint information and the attribute information of each file to the management terminal. It should be noted that the client may also check whether a file is added to the terminal or not in real time, or delete the file; if the newly added file exists, fingerprint information of the newly added file needs to be extracted, and the control terminal uploads the fingerprint information and attribute information of the newly added file to a management terminal; if a certain file is deleted, the control terminal is required to indicate the management terminal to delete the attribute information and the fingerprint information of the file; in addition, the management terminal can independently store the information (such as fingerprint information and attribute information) uploaded by each terminal so as to ensure that the attribute information and the fingerprint information of the file in each terminal stored on the management terminal are synchronous with the file stored on the terminal.

Thus, the management terminal stores the attribute information and the fingerprint information of the file in each terminal, for example, the management terminal stores the attribute information and the fingerprint information of the file in the active terminal, and the attribute information and the fingerprint information of the file in the target terminal. The management terminal can directly read the information from the local when acquiring the attribute information of each file in the source terminal in step 310, and can directly read the information from the local when acquiring the fingerprint information of each first file and each file in the target terminal in step 311, thereby greatly improving the file sharing efficiency. In addition, redundant information (such as fingerprint information of a file) is not stored in the server, so that the stability of the server can be ensured, and the storage pressure of the server is reduced. In addition, each file only has one fingerprint information in the embodiment of the invention, so the complexity of storing and maintaining the fingerprint information is low, and the load of the file synchronization system is low.

Further, the format of the target attribute information belongs to a preset format set, and after receiving the fingerprint information and the attribute information sent by each terminal, the management terminal can convert the format of the attribute information of the file into the format in the preset format set, such as: the attribute information of a certain file before format conversion includes: creation time (x year × month × day × time × minute × second), creation place (x longitude × latitude), where "x" means "some"; the attribute information of the file may include, after the converting: time created (x year x month), place created (x city). In this way, the management side can directly compare whether the target attribute information is the same as the attribute information of each file in the source terminal to determine the first file in step 309, and does not need to determine the first file by comparing whether the attribute indicated by the target attribute information is the same as the attribute indicated by the attribute information of the file, thereby further improving the efficiency of file sharing.

Optionally, the sharing request sent by the source terminal to the target terminal in step 301 may further include: and sharing the validity period of the first file set, wherein the sharing indication information generated by the target terminal also can include the validity period. After step 317, the management side may further repeat steps 310 to 314 and step 317 in the valid period, and the target server may perform

steps

315 and 316 each time receiving the download instruction information sent by the management server. Therefore, the first file can be automatically and repeatedly shared within the validity period, and the file sharing efficiency is improved.

In the related art, when two terminals are synchronized with the same server, the server synchronizes with the two terminals, so that the two terminals and the server all store completely identical files. That is, one of the two terminals may share all local files to the other terminal through the server, but the related art cannot realize that a certain terminal shares part of local files to the other terminal. Moreover, if the user of one terminal wants to delete the file 1, the user of the other terminal does not want to delete the file 1, and when the one terminal deletes the local file 1, both the server and the other terminal delete the local file 1, so that different requirements of different users on the files in the terminals cannot be met. In the embodiment of the present invention, through setting the target attribute information, the source terminal can share the file satisfying the restriction condition (the restriction condition is the attribute indicated by the target attribute information) with the target terminal, so that a certain terminal can share a part of the local file with another terminal. In addition, the file is deleted by any one of the source terminal and the target terminal, the file in the other terminal is not influenced, and different requirements of different users on the file in the terminal can be met.

In addition, in the embodiment of the present invention, the first file set includes: the file whose attribute indicated by the attribute information includes the attribute indicated by the target attribute information is taken as an example, in practical application, the first file set may also be a certain file or certain files that include the attribute specified by the source user, which is not limited in this embodiment of the present invention.

In summary, when the source terminal and the target terminal are respectively synchronized with different server files, in the embodiment of the present invention, the management end in the file synchronization system can manage the network addresses of the files in the source server, so that the management end can perform an indication of related information of file sharing between the source server and the target server, so as to achieve a purpose of sharing the files that the source terminal needs to share to the target terminal through the target server.
