Detailed Description

The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present application, but not all embodiments. Based on the embodiments of the present application, all other embodiments obtained by the person skilled in the art based on the present application are included in the scope of protection of the present application.

In the prior art, users typically upload and download files through FTP (FILE TRANSFER Protocol) or OSS (Object Storage Service ) technologies. The existing scheme for users to remotely acquire and send networking unit files using a terminal based on FTP protocol or OSS technology is shown in fig. 1.

Referring to fig. 1, a flow chart of a file transfer method in the prior art is shown, and the method includes the following steps S101-S108.

Step S101, uploading the specified file by the network connection unit periodically.

Specifically, the network connection unit periodically uploads the agreed network connection unit file to the server.

Step S102, the server stores the network connection unit file.

Specifically, the server stores the received network connection unit file, and after receiving a download request for the network connection unit file sent by the terminal, the server sends the stored network connection unit file to the terminal.

Step S103, the terminal retrieves the server.

Specifically, the terminal determines the network connection unit file to be downloaded by accessing the network connection unit file information stored in the server.

In step S104, the server provides a list of files that the device is operable to.

Specifically, the server may display the network connection unit file information stored in the server according to a directory form and form a corresponding directory file, so that the terminal accesses the network connection unit file information.

Step S105, the terminal downloads the corresponding file.

Specifically, after the terminal determines the network connection unit file to be downloaded through the access server, the network connection unit file is downloaded.

And S106, uploading the networking unit file by the terminal.

Specifically, the terminal uploads the specific file to the server according to the preset program.

In step S107, the server temporarily stores the file and notifies the network connection unit to download.

Specifically, the server stores the specific file uploaded by the terminal, so as to be used for sending the specific file to the network connection unit later.

Step S108, the networking unit downloads the file and replaces the file.

Specifically, after receiving the download instruction sent by the server, the network connection unit downloads the specific file, and uses the specific file to directly cover and replace the stored file with the same name as the specific file.

In the existing file transmission scheme provided by the embodiment shown in fig. 1, since the network connection unit cannot predict the file required by the terminal, only the preset appointed file can be uploaded to the server, the user can only download the appointed file by using the terminal, so that the selectivity and flexibility of the process of acquiring the file by the terminal are poor, the appointed file uploaded by the network connection unit is not necessarily the file actually required by the terminal, namely, the network connection unit uploads the file of which part cannot be acquired by the terminal, so that the waste of file transmission resources and bandwidth of the network connection unit and the waste of storage resources of the server are caused; similarly, the user can only upload specific files according to the preset program using the terminal, so the selectivity and flexibility of the existing file transmission scheme are poor.

In order to solve the above problems, embodiments of the present invention provide a file transmission system, a method, a terminal, a server, a network connection unit, and an apparatus, which are specifically described below.

First, a file transfer system provided by an embodiment of the present invention will be described.

Fig. 2 is a schematic structural diagram of a first file transfer system according to an embodiment of the present invention, where the system includes a terminal 201, a server 202, and a network connection unit 203. Wherein the server 202 is in communication connection with the terminal 201, and the server 202 is in communication connection with the network connection unit 203.

Specifically, the network connection unit 203 may be a mobile phone, a tablet computer, a computer, or other devices. The terminal 201 and the networking unit 203 may each transmit a file to the server 202 or acquire a file from the server 202. The above-mentioned terminal 201 and the network connection unit 203 may be in a public network environment or a local area network environment, which is not limited in the embodiment of the present invention, but if the terminal 201 and the network connection unit 203 are in the same local area network, the security of file transmission may be improved.

Fig. 3 is a flowchart of a first file transfer method according to an embodiment of the present invention, where the method includes the following steps S301 to S308.

In step S301, the networking unit 203 transmits the latest file information of the networking unit file stored in itself to the server 202.

Specifically, the file information may be related information such as a file directory, a file feature code, or file generation time and modification time, which can indicate the identity of the file, and the file information may be stored in a table in a list form.

Specifically, when the network connection unit 203 and the server 202 are in a communication connection state in which file exchange is possible for the first time, the network connection unit 203 transmits the file information to the server 202. Then, the network connection unit 203 detects the network connection unit file stored by itself at intervals of a preset detection period, and when detecting that the network connection unit file changes, sends new file information corresponding to the changed network connection unit to the server 202. The preset detection period may be 2 minutes, 5 minutes, 10 minutes, or the like, and may be set according to actual needs, which is not limited in the embodiment of the present invention.

In step S302, the server 202 stores the file information.

Specifically, the server may store the above file information in the form of a table or in a database.

In step S303, the server 202 transmits the file information to the terminal 201.

Since the file information may be related information indicating the identity of the file, such as a file directory, a file feature code, or a file generation time and a modification time, the file information may be displayed on a display of the terminal 201 after the terminal obtains the file information, and a user may determine a target network association unit file to be obtained at the terminal 201 based on the file information.

In one embodiment of the present invention, the terminal 201 may display the file information in a browser.

In step S304, the terminal 201, after receiving a file acquisition instruction for a target network connection unit file, which is input by the user based on the file information, transmits a file acquisition request for acquiring the target network connection unit file to the server 202.

Specifically, since the file information is not the file information of a specific type of file agreed according to a certain rule, it may be the file information of all the network connection unit files stored in the network connection unit 203. Therefore, the user has a great selectivity in retrieving the file information at the terminal 201, so that a file acquisition instruction for the target network connection unit file can be input at the terminal 201 as needed.

Specifically, after receiving the file acquisition instruction, the terminal 201 generates the file acquisition request based on the file acquisition instruction, where the file acquisition request may include information capable of determining the identity of the target network connection unit file, such as a file name, a file feature code, or a file generation/modification time of the target network connection unit file. Then, the terminal 201 transmits the file acquisition request to the server 202 to acquire the target network connection unit file.

In step S305, the server 202 transmits the target network connection unit file to the terminal 201 after receiving the file acquisition request.

Since the file acquisition request includes information capable of determining the identity of the target network connection unit file, the server 202 can determine the target network connection unit file to be transmitted to the terminal 201 after receiving the file acquisition request. After obtaining the target network connection unit file based on the file acquisition request, the server 202 transmits the target network connection unit file to the terminal 201 so that the user acquires the target network connection unit file at the terminal 201.

In step S306, the terminal 201, upon receiving a file transmission instruction input by the user indicating that the target terminal file is to be transmitted to the internet connection unit 203, transmits a file transmission request for the target terminal file to the server 202.

Specifically, the target terminal file is not a specific type of file agreed according to a certain rule, but may be any type of terminal file determined by the user at the terminal 201 as needed. The terminal 201 generates the file transmission request based on the file transmission instruction, and transmits the file transmission request to the server 202 to transmit the target terminal file, so that the internet connection unit 203 finally receives the target terminal file.

In step S307, the server 202 transmits the target terminal file to the network connection unit 203 after receiving the file transmission request.

Specifically, the server 202 may obtain the target terminal file based on the file transmission request, and transmit the obtained target terminal file to the networking unit 203.

In step S308, the networking unit 203 receives the target terminal file.

Specifically, the networking unit 203 stores the target terminal file in the networking unit 203 after receiving the target terminal file. Thus, the user is finished transmitting the target terminal file to the networking unit 203 through the terminal 201.

In one embodiment of the present invention, after the step S308, the following steps A1-A4 are further included.

Step A1: after receiving the target terminal file, the networking unit 203 stores the target terminal file in a preset temporary directory.

Step A2: the networking unit 203 detects whether a file with the same name as the file of the target terminal exists in a preset target directory.

Specifically, the networking unit 203 determines whether the target terminal file exists in the target directory by comparing file names.

Step A3: if not, the networking unit 203 stores the target terminal file in the target directory.

Specifically, if the networking unit 203 does not detect the homologous file in the target directory, it considers that the target terminal file does not exist in the target directory, and at this time, the target terminal file may be directly moved from the temporary directory to the target directory.

Step A4: if so, the networking unit 203 updates the same name file to the target terminal file when the same name file is not used.

Specifically, if the networking unit 203 detects the same-name file in the target directory, the use state of the same-name file needs to be considered when moving the target terminal file from the temporary directory to the target directory. When the same-name file is in an unused state, normal use of the same-name file is not affected by updating the same-name file, and if the same-name file is in a use state, the same-name file can be updated after the same-name file is used, which can be called as an intelligent merging file, so that the influence on the behavior of using the same-name file can be avoided.

In one embodiment of the present invention, the networking unit 203 may move the target terminal file from the temporary directory to the target directory when the same-name file is not used, and replace the same-name file with the target terminal file.

In another embodiment of the present invention, the above step A4 may be implemented by the following step A4 a.

Step A4a: if so, the networking unit 203 updates the content of the same name file to the content of the target terminal file when the same name file is not used.

Specifically, after the internet connection unit 203 updates the content of the same name file to the content of the target terminal file, the same name file is replaced, and only the target terminal file is stored in the internet connection unit 203.

From the above, the network connection unit stores the target terminal file by adopting the scheme provided by the embodiment of the invention, and the network connection unit stores the target terminal file in the temporary directory instead of directly storing the target terminal file in the target directory after acquiring the target terminal file, so that the interference of writing the same-name file in the target directory to the use state of the same-name file when the same-name file in the target directory is being used can be avoided.

In yet another embodiment of the present invention, the following steps B1-B5 are further included before the step S301.

In step B1, the terminal 201 transmits the device information of the networking unit 203 to the server 202.

Specifically, the device information may include information such as a device name, a MAC (MEDIA ACCESS Control Address) Address, and an operating system version of the network unit 203. The device information has unique correspondence with the network connection unit 203.

In step B2, the server 202 transmits initialization data of the networking unit 203 to the terminal 201 based on the device information of the networking unit 203.

The initialization data of the networking unit 203 includes: authentication information for performing security authentication with the server 202.

Specifically, the server 202 may generate the initialization data uniquely corresponding to the networking unit 203 based on the device information. The initialization data may include CA (Certification Authority, certificate authority) certificates, networking unit certificate private keys, initialization configuration parameter files, and the like.

And step B3, the terminal 201 transmits initialization data of the networking unit 203 to the networking unit 203 based on the network connection with the networking unit 203.

Specifically, the terminal 201 deploys the initialization data to the network connection unit 203 through a secure path preset between the terminal 201 and the network connection unit 203, for example, if the terminal 201 and the network connection unit 203 are in the same lan, the terminal 201 may deploy the initialization data to the network connection unit 203 through the lan.

In step B4, the networking unit 203 sends a security authentication request to the server 202 based on the authentication information in the initialization data.

Specifically, the security authentication request corresponds to the initialization data and has unique correspondence with the network connection unit 203.

In step B5, the server 202 performs security authentication on the internet connection unit 203 in response to the security authentication request.

Specifically, after the server 202 completes the security authentication on the network connection unit 203 based on the security authentication request, it may be determined that a secure network communication connection is established between the server 202 and the network connection unit 203, and data may be transmitted between the two without risk.

On the basis of the embodiment of the invention shown in fig. 3, the embodiment of the invention provides the embodiment shown in fig. 4.

Referring to fig. 4, a flowchart of a second file transfer method according to an embodiment of the present invention is shown, and compared with the embodiment shown in fig. 3, the above step S305 may be implemented by the following steps S305A-S305F.

In step S305A, the server 202 detects whether the target network connection unit file is stored after receiving the file acquisition request.

Specifically, since the file acquisition request includes information capable of determining the identity of the target network connection unit file, the server 202 may determine, based on the file acquisition request, the target network connection unit file that needs to be sent to the terminal 201. Then, the server 202 detects whether the target network connection unit file is stored in its own storage. Since the speed of accessing the self-cache is faster than that of accessing other storage areas (such as hard disk) when the server searches for the file, in order to improve the efficiency of the server 202 in detecting the target network connection unit file, the server 202 may preferably detect whether the self-cache stores the target network connection unit file.

Based on the detection result, if the server 202 detects that the target networking unit file is stored, step S305B is executed; if the server 202 detects that the target networking unit file is not stored, step S305C is executed.

In step S305B, if the target network connection unit file is stored, the server 202 transmits the stored target network connection unit file to the terminal 201.

Specifically, after the server 202 detects that the target network connection unit file is stored in itself, the stored target network connection unit file is sent to the terminal 201, so that the operation of the user to obtain the target network connection unit file through the terminal 201 is completed.

In step S305C, if the target network connection unit file is not stored, the server 202 transmits a unit file report request for the target network connection unit file to the network connection unit 203.

Specifically, the unit file reporting request includes information capable of determining the identity of the target network connection unit file. When the server 202 detects that the target network connection unit file is not stored in itself, in order to transmit the target network connection unit file to the terminal 201, it is necessary to transmit the unit file report request to the network connection unit 203 so that the network connection unit 203 transmits the target network connection unit file to the server 202.

In step S305D, the networking unit 203 sends the target networking unit file to the server 202 after receiving the unit file report request.

Specifically, the online unit 203 determines, based on the identity information of the target online unit file included in the unit file report request, a unit file to be sent to the server 202, and then sends the unit file to the server 202, so that the server 202 obtains the target online unit file.

In step S305E, the server 202 receives the target network connection unit file transmitted by the network connection unit 203, and then stores the target network connection unit file.

Specifically, the server 202 stores the received target network connection unit file, and may directly send the target network connection unit file to the terminal 201 after receiving a file acquisition request including identity information of the target network connection unit file, so as to improve efficiency of the terminal 201 acquiring the target network connection unit file.

In step S305F, the server 202 forwards the target network connection unit file to the terminal 201.

Specifically, the server 202 forwards the received target network connection unit file sent by the network connection unit 203 to the terminal 201, so that the terminal 201 obtains the target network connection unit file.

As can be seen from the above, in the solution provided in the embodiment of the present invention, after receiving a file acquisition request sent by a terminal, a server detects whether a target network connection unit file corresponding to the file acquisition request is stored in itself, if it detects that the target network connection unit file is stored in itself, then sends the stored target network connection unit file to the terminal, otherwise sends a unit file report request for the target network connection unit file to the network connection unit. And after the network connection unit responds to the unit file reporting request and sends the target network connection unit file to the server, the server sends the target network connection unit file to the terminal. That is, only when the server detects that the target network connection unit file to be acquired by the terminal is not stored, the network connection unit is triggered to upload the unit file to the server, so that the network bandwidth is saved, and the network connection unit and the server flow are saved.

On the basis of the embodiment of the invention shown in fig. 3, the embodiment of the invention provides the embodiment shown in fig. 5.

Referring to fig. 5, a flow chart of a third file transfer method according to an embodiment of the present invention is shown, and compared with the embodiment shown in fig. 3, the above step S307 may be implemented by the following steps S307A-S307F.

In step S307A, the server 202, upon receiving the file transmission request, detects whether or not the target terminal file has been stored.

Specifically, the server 202 determines the target terminal file to be detected based on the target terminal file identity information included in the file transmission request. The server 202 may preferentially detect whether the target terminal file is stored in its own cache, which is advantageous for quickly completing the detection process. If the server 202 detects that the target terminal file is stored, step S307B is executed; if the server 202 detects that the target terminal file is not stored, step S307C is executed.

In step S307B, if the target terminal file is stored, the server 202 transmits the stored target terminal file to the internet connection unit 203.

Specifically, after the server 202 detects that the target terminal file is stored in itself, the stored target terminal file is transmitted to the networking unit 203, and thus the user's operation of transmitting the target terminal file to the networking unit 203 through the terminal 201 is completed.

In step S307C, if the target terminal file is not stored, the server 202 transmits a terminal file report request for the target terminal file to the terminal 201.

Specifically, the terminal file reporting request includes information capable of determining the identity of the target terminal file. When the server 202 detects that the target terminal file is not stored in itself, in order to transmit the target terminal file to the internet connection unit 203, it is necessary to transmit the terminal file report request to the terminal 201 so that the terminal 201 transmits the target terminal file to the server 202.

In step S307D, the terminal 201, upon receiving the terminal file report request, transmits the target terminal file to the server 202.

Specifically, the terminal 201 determines a terminal file to be transmitted to the server 202 based on the identity information of the target terminal file included in the terminal file report request, and then transmits the terminal file to the server 202, so that the server 202 obtains the target terminal file.

In step S307E, the server 202 receives the target terminal file transmitted from the terminal 201, and then stores the target terminal file.

Specifically, the server 202 stores the received target terminal file, and may directly send the target terminal file to the internet connection unit 203 after receiving a file sending request including the identity information of the target terminal file, so as to improve the efficiency of the terminal 201 sending the target terminal file to the internet connection unit 203.

In step S307F, the server 202 forwards the target terminal file to the networking unit 203.

Specifically, the server 202 forwards the received target terminal file sent by the terminal 201 to the networking unit 203, so that the networking unit 203 obtains the target terminal file.

In one embodiment of the present invention, the above step S306 may be implemented by the following step C.

Step C: the terminal 201, upon receiving a file transmission instruction from a user to transmit a target terminal file to the internet connection unit 203, transmits a file transmission request including a target file feature code of the target terminal file to the server 202.

Specifically, since each file has a unique corresponding file feature code, the target file feature code can uniquely identify the target terminal file.

The above step S307A may be implemented by the following step D.

Step D: after receiving the file sending request, the server 202 detects whether a file with a file feature code being the target file feature code exists in the stored files, and if so, determines that the target terminal file is stored in the server 202; if not, it is determined that the target terminal file is not stored in the server 202.

Specifically, the server 202 only needs to detect whether the file feature code of the stored file is the same as the target file feature code, so as to determine whether the target terminal file is stored in the server itself, so that the server can complete the detection of the target terminal file based on the target file feature code.

In the above-mentioned scheme provided by the embodiment of the invention, when the user uses the terminal to send the target terminal file to the network connection unit, the target terminal file is not directly sent to the server. After receiving a file sending request sent by a terminal, the server firstly detects whether a target terminal file corresponding to the file sending request is stored in the server, if the target terminal file is detected to be stored in the server, the server sends the stored target terminal file to the internet connection unit, otherwise, a terminal file reporting request aiming at the target terminal file is sent to the terminal. After the terminal sends the target terminal file to the server in response to the terminal file reporting request, the server sends the target terminal file to the internet connection unit. That is, only when the server detects that the target terminal file which the terminal wants to send is not stored in the server, the terminal can send the target terminal file to the server, so that the terminal is prevented from repeatedly sending the file stored in the server, the bandwidth of the server is saved, and the traffic of the terminal and the server is saved.

Referring to fig. 6, a schematic structural diagram of a second file transfer system according to an embodiment of the present invention is provided. In fig. 6, the first service server 601, the second service server 602 and the third service server 603 are all communicatively connected to the gateway server 604, the gateway server 604 is further communicatively connected to the firewall 605, the firewall 605 is communicatively connected to the remote operation user 607, the fourth accessed device 608 and the second router 609 through the first router 606, and the first accessed device 610, the second accessed device 611 and the third accessed device 612 are communicatively connected to the second router 609, respectively.

Specifically, the first service server 601, the second service server 602, and the third service server 603 refer to the servers described above, the remote operation user 607 refers to the terminals described above, and the fourth accessed device 608, the first accessed device 610, the second accessed device 611, and the third accessed device 612 refer to the networking units described above.

Specifically, the above-mentioned access manner of the communication connection may be a transmission communication medium such as 4G (the 4th generation mobile communication technology, fourth generation mobile communication technology)/5G (the 5th Generation Mobile Communication Technology, fifth generation mobile communication technology), optical fiber, etc.

Referring to fig. 7, a flowchart of a file information transmission method according to an embodiment of the present invention is provided, and the method includes the following steps S701-S712.

In step S701, the terminal registers a new user.

Specifically, the user uses the terminal to send a new user account registration request to the server.

In step S702, the server verifies the user information through authentication methods such as short message verification codes and biometric identification.

Specifically, after receiving the new user account registration request, the server may notify the terminal to set a user name, or may automatically allocate the user name to the terminal according to a preset program. Then, the user can input the short message verification code at the terminal by sending the short message verification code to the terminal, so that the user information is verified; the user information can also be verified by initiating a biometric authentication mode such as a face recognition request to the terminal.

In step S703, the server creates an account for the user.

Specifically, after the user information is verified, the server creates an account for the user, and the user can log in the account at the terminal to access the server.

In step S704, the terminal registers the network connection unit information to the server.

Specifically, the terminal stores network connection unit information such as a device name, a MAC address, and an operating system version of a network connection unit to which the user wants to transfer a file, in advance, and the network connection unit information has unique correspondence with the network connection unit.

Step S705, the server records network connection unit information, issues certificates and issues CA related information.

Specifically, the server generates initialization data uniquely corresponding to the networking unit based on the networking unit information, where the initialization data includes related information such as a certificate, a CA, and the like.

In step S706, the terminal views the related information of the network connection unit through the network connection unit list.

Specifically, the user determines the networking unit with which file transfer is desired by looking at the above-described list of networking units at the terminal.

In step S707, the terminal embeds the initialization data issued by the server in the networking unit.

Specifically, the terminal deploys the initialization data to the networking unit through a secure path preset between the terminal and the networking unit.

In step S708, the network connection unit accesses the server by initializing data.

Specifically, the network connection unit generates a corresponding security authentication request based on the initialization data, and sends the security authentication request to the server.

Step S709, the network connection unit authenticates the server.

Specifically, after the server responds to the security authentication request, the network connection unit completes the security authentication with the server, and the network connection unit and the server can mutually transmit data without risk.

In step S710, the networking unit uploads the working area file information.

Specifically, the working area file directory refers to the file information of the network connection unit file, that is, the network connection unit sends the file information of the network connection unit file stored by itself to the server.

In step S711, the server records the work area file information.

Specifically, the working area file information refers to the file information of the network connection unit file, and the server records the file information of the network connection unit file, so that a user can browse the file information of the network connection unit file through the terminal.

Step S712, the terminal browses the network connection unit working area file list.

Specifically, the work area file list refers to a list in which file information of the aforementioned network connection unit file is recorded. Because the file information of the network connection unit file is recorded in the server, a user can browse the file information of the network connection unit file through the working area file list after accessing the server through the terminal, so that the network connection unit file to be acquired is determined.

As can be seen from the above, in the file transmission method provided in the embodiment shown in fig. 7, the server completes the registration of the new user account through the authentication of the terminal, and the server enables the network connection unit to access the server through the authentication with the network connection unit and can perform the mutual transmission of data without risk. Because the short message verification code and the biological identification used in the authentication process have unique correspondence with the terminal, and the used initialization data have unique correspondence with the network connection unit, the security of the file transmission system can be ensured after the authentication is finished.

Referring to fig. 8, a flowchart of a fourth file transfer method according to an embodiment of the present invention is shown, and the method includes the following steps S801 to S820.

In step S801, the internet connection unit retrieves file information.

Step S802, the network connection unit reports to the server.

In step S803, the network connection unit detects a change in file information in the work directory.

In step S804, the server stores the file information reported by the network connection unit.

In step S806, the server represents the file information in the form of a list of files in the network connection unit working area.

In step S807, the terminal switches the directory and browses the file information through the work area file list.

In step S808, the terminal reports a file acquisition request for downloading the target network connection unit file to the server.

In step S809, the server detects the target network connection unit file in the cache.

In step S810, the server determines whether the target network connection unit file exists.

Specifically, if the server detects the target network connection unit file in the cache, determining that the target network connection unit file exists, otherwise, determining that the target network connection unit file does not exist.

If not, steps S811-S812 are performed, otherwise step S813 is performed.

In step S811, the networking unit uploads the target networking unit file to the server.

In step S812, the server stores the target network connection unit file in the temporary directory and responds to the terminal.

Step S813, the terminal obtains the target network connection unit file.

In step S814, the terminal uploads a file transmission instruction for the target terminal file to the server.

In step S815, the server detects whether the target terminal file exists in the cache through the file feature code.

In step S816, the server determines whether the target terminal file exists.

If so, step S818 is performed, and if not, step S817 is performed.

In step S817, the terminal uploads the target terminal file to the specified directory.

In step S818, the server notifies the network connection unit to download the target terminal file.

And step S819, the network connection unit downloads the target terminal file and stores the target terminal file into the temporary directory.

Step S820, the network connection unit intelligently merges the target terminal files.

Specifically, the steps S801 to S820 are similar to the embodiments of the file transfer system described above, and will not be described herein.

From the above, the file transmission method provided by the embodiment shown in fig. 8 can realize the file transmission between the terminal and the network connection unit according to the requirement of the user, so as to meet the specific file transmission requirement of the user. And the network connection unit does not need to periodically upload the network connection unit file to the server. After receiving a file acquisition request sent by a terminal, a server firstly detects whether a target network connection unit file corresponding to the file acquisition request is stored or not, if the target network connection unit file is detected to be stored, the stored target network connection unit file is sent to the terminal, otherwise, a unit file reporting request aiming at the target network connection unit file is sent to the network connection unit. And after the network connection unit responds to the unit file reporting request and sends the target network connection unit file to the server, the server sends the target network connection unit file to the terminal. That is, only when the server detects that the target network connection unit file to be acquired by the terminal is not stored, the network connection unit is triggered to upload the unit file to the server, so that the network bandwidth is saved, and the network connection unit and the server flow are saved.

In addition, when the user uses the terminal to send the target terminal file to the network connection unit, the target terminal file is not directly sent to the server first. After receiving a file sending request sent by a terminal, the server firstly detects whether a target terminal file corresponding to the file sending request is stored in the server, if the target terminal file is detected to be stored in the server, the server sends the stored target terminal file to the internet connection unit, otherwise, a terminal file reporting request aiming at the target terminal file is sent to the terminal. After the terminal sends the target terminal file to the server in response to the terminal file reporting request, the server sends the target terminal file to the internet connection unit. That is, only when the server detects that the target terminal file which the terminal wants to send is not stored in the server, the terminal can send the target terminal file to the server, so that the terminal is prevented from repeatedly sending the file stored in the server, the bandwidth of the server is saved, and the traffic of the terminal and the server is saved.
