The file transmission method provided by the invention can also be applied to realize that the device 102 transmits the local file to the device 101, and the device 103 can download the file from the device 101, at this time, the device 101 is used as a file transmission media device.
The file transmission method provided by the embodiment of the present invention will be further explained with specific embodiments in conjunction with the drawings, and the embodiments do not limit the embodiment of the present invention.
Fig. 2 is a flowchart illustrating a file transmission method according to an embodiment of the present invention, where the method is applicable to a server, in an example, the server is the server 104 illustrated in fig. 1. As shown in fig. 2, the method specifically includes:
and S21, when the file collection requirement of the first equipment is determined, generating a resource link corresponding to the first equipment.
In the system architecture shown in fig. 1, the first device refers to device 101 and the second device refers to device 102.
As an embodiment, in an application, when it is determined that a first device needs to collect a file, a resource link corresponding to the first device is generated, where the resource link corresponding to the first device refers to a storage address where the file is collected and stored in the first device, and the resource link points to the first device.
Further, how the manner of determining whether the first device needs to collect the file is implemented is exemplified by the embodiment of fig. 3, and will not be described in detail here.
And S22, controlling the second device to transmit the file to the first device when receiving the file transmission request sent by the second device based on the resource link.
For one embodiment, after step S21 is completed, the server may send the element including the resource link to the first device, so that the first device can expose the element. Optionally, the element includes at least one of: two-dimensional code, pick-up code, URL address.
As an alternative implementation, the second device may scan the two-dimensional code to access a file transfer service web page provided by the server 104. As another alternative implementation, the URL address and the pickup code may be input by the user in a browser installed on the second device, and the second device accesses the file transfer service web page provided by the server 104 based on the URL address and the pickup code input by the user.
Further, the user can click the 'upload file' icon on the file transfer service webpage, and when the second device detects that the 'upload file' icon is triggered, the second device displays a file selection interface so that the user can select the file to be transferred. Furthermore, after the user selects the file to be transmitted, the user clicks the "submit" icon, and when the second device detects that the "submit" icon is triggered, the second device can send a file transmission request to the server.
In step S22, the server 104 controls the second device to transfer the file to the first device when receiving a file transfer request sent by the second device based on the resource link. How to control the second device to transmit the file to the first device is described below by the embodiment shown in fig. 3, and will not be described in detail here.
S23, after the resource link corresponding to the first device is generated, if the file transmission request is not received within a first preset time period, deleting the resource link.
After the file is stored locally in the first device, corresponding storage address information is generated and fed back to the server 104, the server 104 adds the storage address to a url address suffix and generates a digital combined pickup code, and other devices can enter a file transmission service through a resource link and download the file according to the pickup code.
Optionally, if no file transmission request sent by any device is received within a first preset time (for example, 10 minutes), the resource link is invalidated and deleted.
According to the file transmission method provided by the embodiment of the invention, when a server determines that a first device needs to collect files, a resource link corresponding to the first device is generated; when a file transmission request sent by the second device based on the resource link is received, the second device is controlled to transmit the file to the first device, so that the first device can receive the file transmitted by other devices without inputting the resource link and other operations at the first device end by a user, and therefore the file can be conveniently and quickly transmitted to the first device under the condition that the second device is not convenient for the user to input. Meanwhile, too much hardware is not needed to participate, and communication friends are not needed to be established, so that the file transmission process is simplified, and the file transmission is more convenient and faster.
Fig. 3 is a flowchart of an embodiment of step S21 according to an embodiment of the present invention, and as shown in fig. 3, the method specifically includes:
and S31, receiving the file collection request sent by the first device.
As an embodiment, in the application, a corresponding client application may be installed on the first device to provide the file transfer service. Based on this, the user may launch a client application installed on the first device, clicking a "collect files" icon on a display interface of the client application. The first device, upon detecting that a "collect file" icon on the client application display interface is triggered, may then send a file collection request to the server to request collection of the file. In this manner, the server may receive the file collection request sent by the first device.
Steps S32 to S34 are explained in a unified manner as follows:
and S32, determining the file collection state of the first device.
And S33, if the file collection state indicates that the file is to be collected.
And S34, determining that the first device needs to collect files.
As an optional embodiment, in the application, if the first device does not have any input function, such as an outdoor advertisement screen, based on this, the file collection state of the first device may be set to be in the file to-be-collected state at every moment in advance, and the server may change the resource link corresponding to the first device according to the preset time; the file collection state of the first device can be actively acquired through the server according to the preset time. And if the file collection state of the first equipment is to be collected, determining that the first equipment needs to collect the files.
The embodiment of the invention can respectively determine whether the first equipment needs to collect files or not aiming at the first equipment with the input function and the first equipment without the input function.
Fig. 4 is a flowchart of an embodiment of step S22 according to an embodiment of the present invention, and as shown in fig. 4, the method specifically includes:
s41, determining whether the second IP address and the acquired first IP address of the first device belong to the same network segment, if so, executing the step S42, and if not, executing the step S43.
And S42, if yes, controlling the second device to establish a point-to-point communication connection with the first device, and controlling the second device to transmit a file to the first device through the point-to-point communication connection.
S43, if not, controlling the second device to transmit the file to the device, and forwarding the file to the first device based on the first IP address.
Steps S41 to S43 are explained in a unified manner as follows:
as can be seen from the above description, in the embodiment of the present invention, after receiving the file transmission request sent by the second device based on the resource link, the server does not directly control the second device to transmit the file to the server, and then transmits the file to the first device, but first determines whether the first device and the second device are in the same lan. It can be understood that, if the first device and the second device are in the same lan, it means that the first device and the second device can directly communicate with each other, and further, the second device can directly transmit files to the first device through the communication connection with the first device, so that the transmission efficiency can be improved. If the first device and the second device are not in the same local area network, the second device transfers the files to the server, and then the server transmits the files to the first device, so that remote transmission of different networks is achieved.
For one embodiment, the server may determine whether the first device and the second device are within the same local area network by: and determining whether the IP address (for convenience of description, hereinafter referred to as a second IP address) of the second device carried in the file uploading request and the IP address of the first device belong to the same local area network. If yes, it means that the first device and the second device are in the same local area network, and if no, it means that the first device and the second device are not in the same local area network.
Wherein, the server may obtain the IP address of the first device (hereinafter, referred to as the first IP address for convenience of description) in the following manner: and (6) registering.
As an embodiment, in case the first device and the second device are on the same local area network, the peer-to-peer communication connection of the first device and the second device may be controlled. As an alternative implementation, the server may send the IP address and the device information of the second device to the first device, and the first device establishes a peer-to-peer communication connection with the second device based on the received information.
Alternatively, a point-to-point communication connection may be established between the two devices based on a Transmission Control Protocol (TCP), a User Datagram Protocol (UDP), or the like.
Further, the second device is controlled to transmit the file to the first device through the peer-to-peer communication connection established with the first device. The file transmission may be instructing the first device to download the file from the second device, or instructing the second device to actively send the file to the first device.
Further, the first device saves the file in a local storage address.
As an embodiment, in case that the first device and the second device are not in the same local area network, the second device is controlled to transmit the file to the server. The transmission method may be that the server downloads the file directly from the second device, or the server sends a file transmission address to the second device, and the second device uploads the file to the server according to the file transmission address.
Further, the server forwards the file to the first device according to the IP address and the device information of the first device, and the first device stores the file in the local storage address after receiving the file.
For example, if the first device is connected to an intranet of a company and the second device uses a 4G network, the first device and the second device are not in the same lan; or, if the first device and the second device are not in the same city, the first device and the second device are not in the same local area network.
According to the file transmission method provided by the embodiment of the invention, the point-to-point communication connection between the second device and the first device is established by judging whether the second device and the first device are in the same local area network or not, so that the file is directly transmitted, or the second device transmits the file to the server, and then the server transmits the file to the first device; therefore, the file can be rapidly transmitted, and time is saved.
Currently, in a conference scenario, files are also transferred between conference participants, such as the device 102 transmitting the files to the device 103. This is illustrated by the embodiment shown in fig. 5.
Fig. 5 is a schematic flowchart of a process after step S22 according to an embodiment of the present invention, as shown in fig. 5:
s51, when a file downloading request sent by a third device based on the resource link is received, determining whether a third IP address of the third device and the first IP address carried in the file downloading request belong to the same network segment. If so, go to step S52, otherwise, go to step S53.
And S52, if yes, controlling the first device to transmit the file to the third device.
And S53, if not, controlling the device to transmit the file to the third device.
As one example, an element of the resource link may be exposed on the first device, and as such, the third device may scan the two-dimensional code in the resource link element to access the file transfer service web page provided by the server. As another alternative implementation, the URL address and the pickup code may be entered by the user in a browser installed on the third device, and the third device accesses the file transfer service web page provided by the server 104 based on the URL address and the pickup code entered by the user.
Further, the user can click a 'download file' icon on the file transfer service webpage, and the second device displays a file selection interface when detecting that the 'download file' icon is triggered, so that the user can select a file to be downloaded. Furthermore, after the user selects the file to be downloaded, the user clicks the download icon, and when the second device detects that the download icon is triggered, the second device can send a file download request to the server.
In step S51, after receiving the file download request sent by the third device based on the resource link, the server first determines whether the third device and the first device are in the same lan, instead of immediately transmitting the file. If the third device and the first device are in the same local area network, it means that the third device and the first device can communicate directly, and further, the first device can directly transmit files to the third device through the communication connection between the first device and the third device, so that the transmission efficiency can be improved. If the third device and the first device are not in the same local area network, the first device transfers the file to the server, and then the server transfers the file to the third device, so that remote transmission of different networks is realized.
In an alternative of the embodiment of the present invention, after the second device is controlled to transmit the file to the device, if the file download request is not received within a second preset time period, the file is deleted.
After the second device transmits the file to the server and the server transmits the file to the first device, if a file downloading request sent by other devices through the resource link is not received within a second preset time (for example, 5 minutes), the resource link is invalid and the resource link is deleted.
In the file transmission method provided by the embodiment of the invention, the point-to-point communication connection between the third device and the first device is established by judging whether the third device and the first device are in the same local area network, and the file is directly transmitted, or the aunt device transmits the file to the server and then the server transmits the file to the third device; therefore, the file can be rapidly transmitted, and time is saved.
