Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 2 is a schematic flowchart illustrating a file transmission method according to an embodiment of the present invention, and fig. 3 is a schematic application diagram illustrating a file transmission method according to an embodiment of the present invention; the file transfer method can be used for a first terminal, wherein the first terminal is used for characterizing any terminal in a network system (such as WLAN); as shown in fig. 2, the file transfer method may include the steps of:
s210, determining the transmission identity of the first terminal.
Specifically, during the file transmission process, the transmission identity of the first terminal may be a transmission party or a reception party. The decision as to the transmitting party or the receiving party in particular is made by the user using the first terminal.
The first terminal may be a smart phone, a wash ink screen reader, a PC (personal computer), or the like.
And S220, if the transmission identity of the first terminal is the transmission party, taking the first terminal as a server, and transmitting the file corresponding to the first file transmission request to the corresponding second terminal when receiving the first file transmission request sent by one or more second terminals with the transmission identities of the receivers in the network system.
Specifically, if the first terminal is the transmission party, the first terminal serves as a server in the network system to provide the file content to be downloaded for the second terminal whose transmission identity is the receiving party.
And S230, if the transmission identity of the first terminal is the receiving party, the first terminal is used as a client, a second file transmission request is sent to a third terminal with the transmission identity as the transmitting party in the network system, and a file corresponding to the second file transmission request transmitted by the third terminal is received.
Specifically, if the first terminal is the receiving party, the first terminal serves as a client in the network system, and obtains the file content that needs to be downloaded from a third terminal whose transmission identity is the transmitting party.
In an example scenario, as shown in fig. 3, a terminal device group a and a terminal B are included in a network system. The terminal device group a includes a terminal a1, a terminal a2, a terminal A3, a terminal a …, and the like.
The terminal B is a server in the network system, and the terminal equipment group A is a client in the network system.
When network book transmission is needed, both the terminal equipment group A and the terminal B need to be added into the same network system. Specifically, both the terminal device group a and the terminal B may be connected to the same WI-FI (Wireless-Fidelity), so that all the terminal devices may join the same Wireless lan (if the terminal devices are PC computers, all the devices may be connected to the same router), and all the terminal devices may join the same network system.
In addition, when the transmission identities are determined, the bookshelves of the terminal device group a and the terminal B are both provided with an entry "WI-FI book transfer", after the user selects "WI-FI book transfer", the terminal displays a popup box, and then the user selects the transmission identities ("transmission parties" or "receiving parties"), and a specific display interface is shown in fig. 4.
If the transmission identity of the first terminal in this embodiment is the transmission party, such as the terminal B in fig. 3, in the file transmission, the terminal B serves as a server to provide the file content to be downloaded for each terminal that needs to download the file in the terminal device group a.
If the transmission identity of the first terminal in this embodiment is the receiving party, for example, the terminal a1 that needs to download the file in the terminal device group a in fig. 3, in the file transmission, the terminal a1 is used as the receiving party, and the content of the file that needs to be downloaded is obtained from the terminal B.
As can be seen from the above embodiments, in the file transmission, any terminal in the network system may be a transmitting party or a receiving party; when the client is a transmission party, the transmission party can be used as a server and receives a first file transmission request sent by a second terminal with one or more transmission identities as receivers in a network system, and the file corresponding to the first file transmission request is transmitted to the corresponding second terminal, namely, the files which need to be downloaded respectively are provided for the second terminals which are used as the clients; when the server side is the client side, the server side can be used as the client side, send a second file transmission request to a third terminal with the transmission identity as the transmission side in the network system, receive a file corresponding to the second file transmission request transmitted by the third terminal, namely obtain a file which needs to be downloaded from the third terminal which is used as the server side, so that one-to-many file transmission between the server side and the client side is realized, and the efficiency of file transmission is improved.
Further, on the basis of the above method embodiment, when performing step 120, the following implementation manners may be included, but are not limited to:
(1-1) storing the transferable files in a designated directory and generating a corresponding downloadable file list.
Specifically, the transferable files may include books that need to be transferred. In order to ensure the security of the terminal device, the transferable file can be stored in a designated directory, and the file of the designated directory can be allowed to be transferred to other terminal devices, and the file which is not imported or stored in the designated directory cannot be transferred by the client. Such as: the specified directory is: sdcars/books, and the format of the transmitted file is TXT, EPUB, UMD, PDF, WORD, etc., and the format suffix is not distinguished from case to case.
In addition, the first terminal can also perform 'removal' on the files already in the specified directory, and the removed files cannot be used for file transmission any more.
And (1-2) outputting first transmission party identification information to enable each second terminal to establish a first communication channel with the first terminal according to the first transmission party identification information.
Specifically, the first terminal outputs the first transmission party identification information, so that the second terminal with the transmission identity as the receiving party can know that the transmission identity of the first terminal is the transmission party according to the first transmission party identification information, establish a first communication channel with the first terminal according to the first transmission party identification information, and send the first file transmission request to the first terminal through the first communication channel.
Such as: the first transmitter identification information is https: //192.168.3.47:15000, the second terminal enters the https: //192.168.3.47:15000 so that the second terminal can establish a first communication channel with the first terminal based on the first transmitter identification information and send a first file transfer request to the first terminal via the first communication channel.
(1-3) when receiving a first file transmission request sent by each second terminal through the first communication channel, sending the downloadable file list to the corresponding second terminal through the first communication channel, so that the corresponding second terminal determines files needing to be downloaded from the downloadable file list.
Specifically, if the first terminal and each of the second terminals are located in the same network system, the first terminal may receive a first file transmission request sent by each of the second terminals through the network system, and send a downloadable file list to each of the second terminals through the network system. The downloadable file lists received by the second terminals can be the same, and after the second terminals receive the download file lists, the download file lists can be analyzed, and the analyzed download file lists are displayed, so that a user can conveniently determine files needing to be downloaded from the download file lists.
(1-4) when a file downloading request sent by each second terminal through the first communication channel is received and the file downloading request includes file information to be downloaded by the second terminal, transmitting file content corresponding to the file information in the designated directory to the corresponding second terminal through the first communication channel based on the file information to be downloaded.
Specifically, the file to be downloaded by the second terminal may be one file in the download file list, or may be multiple files in the download file list. After the first terminal knows the files required to be downloaded by the second terminal, the contents of the files required to be downloaded are obtained from the specified directory, and the contents of the files required to be downloaded are sent to the corresponding second terminal.
Such as: as shown in fig. 3, terminal B is a first terminal, both terminal a1 and terminal a2 are second terminals, the file that terminal a1 needs to download is file 1, and the files that terminal a2 needs to download are file 1 and file 2, at this time, terminal B will obtain the content of file 1 from the designated directory and send it to terminal a1, and obtain the content of file 1 and the content of file 2 and send it to terminal a 2.
As can be seen from the above embodiments, by storing the transferable files in the designated directory and generating the corresponding downloadable file list, the receiver can download the transferable files in the designated directory, thereby ensuring the security of file transfer. In addition, the first transmitter identification information is output, so that all receivers can establish a first communication channel with the first terminal according to the first transmitter identification information and send a first file transmission request to the first terminal through the first communication channel, and the efficiency of requesting file transmission is improved.
Further, on the basis of the above method embodiment, the first transmitter identification information in (1-2) may be an IP (Internet Protocol) address of the first terminal. Wherein the IP address may be an IP address of the first terminal located in the network system (e.g. WLAN).
Correspondingly, after the first terminal outputs its own IP address, the second terminal may establish a first communication channel with the first terminal according to the IP address of the first terminal, and send a first file transmission request to the first terminal through the first communication channel, that is, access the first terminal in the IP address manner to request the first terminal to transmit a file.
Such as: as shown in fig. 5, the IP address of the first terminal is https: //192.168.3.47:15000, the second terminal enters the https: //192.168.3.47:15000 so that the second terminal can establish a first communication channel with the first terminal based on the IP address of the first terminal and send a first file transfer request to the first terminal through the first communication channel.
Further, on the basis of the above method embodiment, the first transmitter identification information in (1-2) may be a device name of the first terminal; when (1-2) is performed, the following implementations may be included, but are not limited to:
and (2-1) if the first terminal is determined not to be provided with the equipment name, setting the equipment name of the first terminal.
Specifically, the device name of the first terminal may be a name set by the user for the first terminal, such as: king of xiao di.
In addition, if it is determined that the first terminal has set the device name, the device name of the first terminal may be directly output.
(2-2) generating a corresponding relation between the equipment name of the first terminal and the IP address of the first terminal, and sending the corresponding relation to a network server, so that the network server stores the corresponding relation and provides the equipment name of the first terminal used for establishing the first communication channel for each second terminal. In addition, the network server may also provide, for each of the second terminals, a correspondence between the device name of the first terminal and the IP address of the first terminal.
Specifically, the IP address of the first terminal may be an IP address of the first terminal located in the network system (e.g., WLAN). Such as: the device name of the first terminal is king-boy King-King-Ki: //192.168.3.47:15000, the first terminal will send the corresponding relationship to the network server for storage.
Correspondingly, after the first terminal stores the correspondence to the network server, the second terminal that needs to download the file may first obtain a list of names of devices of the transmission party in the network system (for example, WLAN) from the network server (as shown in fig. 6), then select the first terminal that provides the file for the second terminal from the list, establish a first communication channel with the first terminal according to the device name of the first terminal, and send a first file transmission request to the first terminal through the first communication channel, that is, access the first terminal by the device name to request the first terminal to transmit the file.
Such as: the second terminal may select the terminal of kingle of the device name of wanese in fig. 6 as a transfer party and request it to transfer a file.
In addition, in the above-mentioned accessing the first terminal by the device name, not only the first communication channel between the first terminal and the second terminal needs to be established, but also the network server needs to provide an interface to be uploaded by the first terminal or to obtain the device name and the IP address data of the transmission party by the second terminal.
It can be seen from the above embodiments that the server outputs the first transmitter identification information, which may be an IP address of the first terminal or an equipment name of the first terminal, so that the receiver can access the server in the form of an IP address and also can access the server in the form of an equipment name, thereby avoiding operations in the prior art that the transmitter terminal needs to scan two-dimensional codes generated by the receiver terminal one by one when a plurality of receiver terminals exist, and realizing that one-to-many file transmission can be performed even if the transmitter terminal does not have a camera (such as an ink-wash screen reader), thereby improving the application range of file transmission.
Further, on the basis of the above method embodiments, when performing (1-4), the following implementations may be included, but are not limited to:
(3-1) receiving file downloading requests sent by the second terminals through the first communication channels.
Specifically, as shown in fig. 3, when the terminal device group a (a1, a2, A3, …) performs wireless network communication with the terminal B, the terminals in the terminal device group a establish first communication channels, i.e., a 1-B, A2-B, A3-B, …, with the terminals B via the WLAN, and the channels are completely independent.
(3-2) adding each of the file download requests to a file download queue.
Specifically, since there may be a plurality of second terminals sending file downloading requests, the file downloading requests may be first added to the file downloading queue and then processed according to a certain rule.
(3-3) processing the file download request in the file download queue through a multithreading mechanism; the multithreading mechanism comprises thread locking, wherein the thread locking is used for representing that when a plurality of threads access the same file at the same time, only one thread can access the file, and other threads are queued to wait;
specifically, thread locking solves the problem of mutual exclusion of resources generated when multiple threads access the same file simultaneously.
The thread locking may refer to that when a plurality of threads simultaneously read and write a certain file or a memory area, it is set that only one thread can request access to the file or the memory area at a time, other threads wait in a queuing manner, and after the access of the thread is completed, the next thread can request access to the file or the memory area.
And (3-4) transmitting the file content which needs to be downloaded by the second terminal in the specified directory to the corresponding second terminal through the first communication channel.
Specifically, as shown in fig. 3, the terminal B is a first terminal, and the terminal B can transmit the file contents that the terminal a1, the terminal a2 and the terminal A3 respectively need to download to the corresponding terminals through mutually independent first communication channels (B-a 1, B-a 2, B-A3 and … …).
Such as: terminal B receives a file download request sent by terminal a1 through channel a 1-B, where the file download request includes a file (e.g., name of book 1) to be downloaded selected by terminal a1, and when the file is transmitted, terminal B transmits the content of book 1 matching the name of book 1 to terminal a1 through network channel B-a 1.
As can be seen from the above embodiments, the server and the client perform information interaction through the first communication channels respectively established by the first terminal and each of the second terminals, and process the file download requests in the file download queue through the multithreading mechanism, so that the reliability of file transmission is improved, especially, the problem of resource mutual exclusion in multithreading is solved through thread locking, and the efficiency of processing the file download requests is improved.
Further, on the basis of the above method embodiment, when performing step 130, the following implementation manners may be included, but are not limited to:
(4-1) acquiring second transmission party identification information, wherein the second transmission party identification information is transmission party identification information output when the third terminal is a transmission party.
Specifically, the third terminal outputs the second transmission party identifier information, so that the first terminal with the transmission identity as the receiving party can know that the transmission identity of the third terminal is the transmission party according to the second transmission party identifier information, establish a second communication channel with the third terminal according to the second transmission party identifier information, and send a second file transmission request to the third terminal through the second communication channel.
Further, the second transmitter identification information in (4-1) above may include an IP address of the third terminal, or a device name of the third terminal provided by a network server.
Specifically, if the second transmission party identification information is the IP address of the third terminal, it can be directly obtained from the third terminal; if the second transmission party identification information is the device name of the third terminal, since the third terminal stores the corresponding relationship between the device name and the IP address to the network server when setting the device name, the device name of the third terminal needs to be acquired from the network server when acquiring the device name.
(4-2) establishing a second communication channel with the third terminal according to the second transmission party identification information, and sending the second file transmission request to the third terminal through the second communication channel.
(4-3) when receiving a downloadable file list sent by the third terminal through the second communication channel, determining files needing to be downloaded from the downloadable file list.
(4-4) sending a file downloading request to the third terminal through the second communication channel, wherein the file downloading request comprises file information required to be downloaded by the first terminal.
And (4-5) receiving the file content corresponding to the file information transmitted by the third terminal through the second communication channel.
It can be seen from the above embodiments that the client can obtain the second transmission party identification information, where the second transmission party identification information may be an IP address of the server or an equipment name of the server, and then can access the server according to the IP address or the equipment name, and download files required by the client from the server, thereby enriching the implementation manner of accessing the server by the client, satisfying one-to-many file transmission between the server and the client, and improving the efficiency of file transmission.
Fig. 7 is another schematic flow chart of a file transmission method according to an embodiment of the present invention. As shown in fig. 7, taking WI-FI book transfer as an example, the client accesses the server in an IP address manner, and the book transmission process between the server and the client:
s700, the server places the downloadable books into a designated directory.
