In order to make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described in combination with specific embodiments of the present invention and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

As mentioned above, the existing technology has security problems. In addition, the existing technology also has other problems. For example, the process of transmitting pictures requires the user ’s mobile device ’s paid network traffic; when the amount of picture data is large, the transmission takes more time; the cloud disk itself may require the user to pay an extra fee; and so on. The solution of the present invention can partially or completely solve the problems mentioned in the background, as well as the problems listed. The scheme of the present invention will be described below.

In the embodiment of the present invention, for both devices transmitting files, for convenience of description, the device receiving the file is referred to as the "first device", and The device that sends the file is called the "second device." The first device and / or the second device may be a mobile device, such as a mobile phone, a tablet computer, a notebook computer, a smart watch, a smart bracelet, a car mobile station, etc .; the first device and / or the second device may also be non-mobile Equipment, such as personal computers (PC), large and medium computers, computer clusters, etc.

These devices are listed as examples only and are not intended to limit the present invention. For example, in the background art example, the first device and the second device are both mobile phones.

Further, a first client is mounted on the first device, and a second client is mounted on the second device. Generally, the first client and the second client belong to the same application.

FIG. 1 is a schematic flowchart of a file transmission method according to an embodiment of the present invention. The first client and the second client are in the same local network (that is, the first device and the second device are in the same local network). The process in Figure 1 uses the first client as the execution body and can include the following steps: S101: The first client obtains address information of the built-in server of the first client in the local area network.

In the embodiment of the present invention, the local area network may be a wireless local area network, such as a Wireless Fidelity (WiFi) network, a Worldwide Interoperability for Microwave Access (WiMAX) network, and the like; The local area network may also be a wired local area network interconnected through a network cable, cable, or optical fiber.

In the embodiment of the present invention, the built-in server of the first client may be It may be established in advance, or may be established immediately when step S101 is performed. The built-in server can be built in at least one application on the first device, or not depend on the application, but in the operating system of the first device, and can even be built in at least one hardware of the first device. In the driver.

The built-in server can provide at least data transmission services in the local area network. The present invention does not limit the transmission protocol on which the data transmission service is based, and may be a Hyper Text Transfer Protocol (HTTP), a File Transfer Protocol (FTP), or a simple file transfer communication Protocol (Trivial File Transfer Protocol, TFTP), etc. Taking HTTP as an example, the built-in server may specifically be an HTTP server (HTTPServer).

In the embodiment of the present invention, the address information of the built-in server in the local area network may be automatically allocated by the local area network, or may be automatically configured by the first client, or may be manually configured by the user in advance. .

The address information may include a local network IP address and a port number. In addition, if the first client has a function variable name in the local network, the address information may include a function variable name and a port number. For ease of use, the address information is generally expressed in the form of a Uniform Resource Locator (URL). For example, the address information of a built-in server of a certain first client can be expressed as follows: "http : //192.168,0.100:15000 ".

Among them, "192.168,0.100" is the LAN IP address of the built-in server, and "15000" is the port number of the built-in server.

It should be noted that URL is an example of a representation form of address information, and is not a limitation on the present invention. In practical applications, other representation forms may also be used to represent address information, such as Extensible Markup Language , XML), etc.

S102: The first client generates a Digital Object Unique Identifier (DOI) containing the address information according to the address information, so that the second client can scan the DOI by scanning the DOI. To send a file to the built-in server.

In the embodiment of the present invention, the DOI includes, but is not limited to, a two-dimensional code, a bar code, a character code, a network function variable name, and the like. The following embodiments are mainly described by taking DOI as a two-dimensional code as an example.

In the embodiment of the present invention, the file may be a picture, or may be another file such as a video, a document, music, or an application installation package.

In the embodiment of the present invention, after the DOI is generated by the first client, the DOI can be displayed directly through the first client in real time; the DOI can be displayed in other ways after being output, for example, printed on a physical object for display, Post impressions through certain apps, and more.

Further, the second client can scan the displayed DOI, parse and obtain the address information contained in the DOI, and then establish a connection with the built-in server according to the address information, and send the file to the built-in server through the connection. The file is a file to be transmitted from the second client to the first client, and the function of scanning the DOI may be supported by the second device or a corresponding hardware device connected to the second device, such as a camera.

It should be noted that during the execution of the process in FIG. 1, the second client It is not necessary to be on the same local area network as the first client. The second client may be in the same local network as the first client only when it needs to perform certain specific actions (for example, scanning a DOI code and sending a file).

S103: The first client obtains the file received by the built-in server.

In the embodiment of the present invention, since the built-in server is located in the first client and belongs to the component of the first client, the “built-in server receives the file”, that is, the “first client receives the file”.

After the first client obtains the file sent by the second client, it can perform further actions on the file. For example, save the file to a specific location (such as saving to a local album, etc.), use a specific application (such as opening with a picture viewer or web browser, etc.) to open the file, or generate a preview interface of the file, and so on. These actions can be continued by the built-in server or by other programs on the first client.

Through the method shown in Figure 1, the first client and the second client can be located on two mobile devices to transfer files. The picture belongs to the file type. These two mobile devices do not need to be connected to the Internet, Third-party servers such as cloud disk servers interact with each other, and only need to use the local area network to complete the transfer of pictures between mobile devices. Compared with the Internet, the security of the local area network is easier to ensure, which can reduce data leakage. Risk, therefore, can solve the problems in the background art in part or in whole.

Not only that, because the file transfer process is based on the local area network, it will not consume the paid network traffic of the mobile devices of both users. Generally speaking, the transmission bandwidth provided by the local area network to users is greater than or even much larger than the paid network bandwidth of the Internet. Therefore, the time required for file transmission can also be reduced. The solution of the present invention also does not require the use of a cloud disk, and therefore, it does not require users to pay extra for using the cloud disk.

In actual applications, in addition to the cloud disk-based image transmission method mentioned in the background technology, the existing technology also has an image communication method based on an instant messaging application. However, the latter generally also requires user equipment to access the Internet, and Image transmission is performed through the Internet. Therefore, there are similar problems with cloud disk-based image transmission methods, and details are not described here. In addition, the existing technology also has a picture transmission method based on Bluetooth or infrared, but this method requires the support of dedicated hardware modules and communication protocols such as Bluetooth technology and infrared technology, and may require users to configure complex technical parameters and implement The cost is high. Compared with this method, the solution of the present invention does not need to add dedicated hardware modules and communication protocols, nor does it require users to configure complicated technical parameters, so the implementation cost is lower.

Based on the method in FIG. 1, the embodiment of the present invention further provides some specific implementation methods and extension solutions of the method, which are described below.

In the embodiment of the present invention, in order to reduce the resource consumption of the first client, the built-in server of the first client does not need to keep the activated state all the time, but when the file needs to be transmitted, it is started by the user's operation. In this case, for step S102, before the first client obtains the address information of the built-in server of the first client in the local network, the first client may also execute: the first client Start the built-in server of the first client. It should be noted that if the built-in server is in a local area network If the address information in the road is pre-configured, the first client can also execute step S101 before the built-in server starts. Accordingly, the built-in server only needs to perform the second client and the built-in server. Just start before establishing a connection.

Further, for the convenience of users, the built-in server may also have a corresponding operation interface (which can be saved as corresponding operation interface information), and the operation interface may include: an interface for displaying on the first client (such as , A control interface for starting a built-in server, etc.), and / or an interface for displaying on a second client (for example, a file transfer interface for selecting a file to be transferred, etc.). The operation interface can include corresponding operation prompt information and operation controls.

The invention does not limit the manner of constructing the operation interface. Generally, a Hypertext Markup Language (HTML), Cascading Style Sheets (CSS), and at least one scripting language (eg, JavaScript, Python, etc.) can be used. Solution to build the interface.

Taking the operation interface as a file transmission interface as an example, for step S102, after generating a DOI containing the address information, the first client can also execute: provide the file transmission interface information to the second client so as to facilitate The second client terminal displays a file transmission interface for sending the file according to the file transmission interface information. Thereby, the operation convenience of the user of the second user end can be improved.

In the embodiment of the present invention, the local area network mentioned earlier may be Think wireless LAN or wired LAN. Considering that users generally use mobile devices to transmit pictures, and mobile devices use wireless communication methods, therefore, in practical applications, the solution of the present invention may be used more in the scenario of wireless local area networks.

At present, the WiFi network is the most widely used wireless local area network. It can be seen almost everywhere in daily life. The widespread use of the WiFi network can bring great convenience to the practical application of the solution of the present invention. Following the example in the background technology, in commercial operation activities, businesses generally provide free WiFi networks for users to use. Based on the solution of the present invention and the WiFi network, users can conveniently share pictures or other pictures other than pictures. file.

The above mainly describes the solution of the present invention by using the first client as the method execution subject. In order to further facilitate understanding, based on the same idea, an embodiment of the present invention also provides a schematic flowchart of another file transmission method, as shown in FIG. 2.

The first client and the second client are in the same local area network. The process in FIG. 2 uses the second client as the execution body and may include the following steps: S201: The second client scans a DOI generated by the first client, where the DOI includes address information of a built-in server in the first client in the local network.

S202: The second client obtains the address information included in the DOI.

In the embodiment of the present invention, the second client scans the DOI and performs analysis to obtain the address information contained in the DOI.

S203: The second client sends a file to the built-in server according to the address information, so that the first client obtains the file received by the built-in server.

In the embodiment of the present invention, the file transmission between the second client and the built-in server is performed on the local area network where the first client and the second client are located, without relying on the Internet. The second client also has a local network IP address in the local network. The second client communicates with the built-in server through its own local network IP address (and a certain port number).

The method of FIG. 2 is substantially the same as the method of FIG. 1, but is described from different perspectives. Therefore, the technical effects of the two are also the same. The technical effects of the method of FIG. 1 have been described in detail above, and are not described here.

Based on the method in FIG. 2, the embodiment of the present invention further provides some specific implementation methods and extension solutions of the method, which are described below.

In the embodiment of the present invention, for step S203, the second client sends a file to the built-in server according to the address information, which may specifically include: the second client according to the address information Establishing a connection with the built-in server through the local area network; the second client sends a file to the built-in server through the connection.

When there are multiple second clients in the local network that need to transmit files to the first client, it is not necessary that all the second clients establish connections with the built-in server. At least one second client and internal Create a server and establish a connection. In this case, each second client that has not established a connection with the built-in server can pass through the second user that has established a connection with the built-in server Send the file to the built-in server.

In the embodiment of the present invention, as mentioned earlier, for the convenience of users, the built-in server may have an interface for displaying on the second client. The interface is provided for use by the second client. The interface may specifically Is a file transfer interface. In this case, sending the file to the built-in server for the second client through the connection may specifically include: the second client obtains the first through the connection. File transmission interface information provided by the client; displaying the file transmission interface according to the file transmission interface information; determining a file selected by the user on the second client through the file transmission interface, and sending the file to the built-in server Send the file.

The process for the second client to obtain the file transfer interface information from the first client is similar to the process of opening a webpage through a browser. In this analogy, the file transfer interface information is equivalent to the webpage file itself or the source code of the webpage, and the address information of the built-in server is equivalent to the webpage URL.

The solutions of the present invention have been described above from the perspectives of the first client and the second client, respectively. An embodiment of the present invention also provides a schematic diagram of an interaction process in a solution of the present invention in an actual application scenario to help understand the solution of the present invention as a whole.

In practical applications, it is the mobile phone a and mobile phone b that interact with each other. However, since the interaction process may involve a two-dimensional code generated by the mobile phone a, And the file transmission interface displayed on the mobile phone b. Therefore, in order to make the interaction process look more logical, the two-dimensional code and the file transmission interface are also independently used as one end of the interaction process.

In FIG. 3, the mobile phone a and the mobile phone b are in the same WiFi network.

Mobile phone a starts the built-in server and generates a QR code and displays it based on the address information of the built-in server in the WiFi network. Mobile phone b scans the QR code and connects to the built-in server to generate file transmission. Interface for selecting pictures to be transmitted, and then sending the pictures selected by the user to the built-in server; phone a receives the pictures and saves them to a local album, thereby completing picture sharing between phones.

The solution of the present invention can be implemented based on existing mobile devices, and can be implemented from a software level without updating hardware. An embodiment of the present invention provides a schematic diagram of a software architecture for implementing the solution of the present invention, as shown in FIG. 4.

In Figure 4, the software architecture can be divided into four layers: the view layer, the tool layer, and the network layer.

In the view layer, a javascript + CSS + HTML solution is used to build a visual interface.

At the tool level, DOI generators are used to generate DOIs, and FileSource modules are used to perform file operations such as saving (received by calling the corresponding application program interface) the files received by the first client.

At the network layer, HTTPServer is used to handle the service that starts the built-in server, HTTPResponse is used to handle the response of the file transfer, and HTTPConnection is used to establish the connection between the built-in server and the second client For connection, AsyncSocket is used to provide the Socket protocol for long-term connection to ensure that the file transfer process is not interrupted.

It should be noted that the software architecture in FIG. 4 is only an example. In practical applications, the layering manner and the names of modules in the architecture may be different from those in FIG. 4.
