Background
The commodity object information service system may include commodity objects related to a judicial auction performed by a department such as a court, in addition to commodity object information issued by a merchant, an individual seller, or a platform. For such merchandise objects, the source of the information is typically inside the court. For example, the court needs to provide information of a commodity object of a specific judicial auction to a commodity object information service system, and then the system can issue the information of the commodity object for a consumer user to browse, purchase and the like. In addition, when a consumer user in the system performs an operation such as purchasing a certain legal shot, the goods object information service system may also need to submit specific user information and the like to a court system, and the like.
However, because information in an intranet of a government department such as a court is often secret-related or internal information, in order to secure data in the intranet and the extranet of the court and prevent hackers from invading the intranet of the court, the intranet and the extranet of the court are completely isolated from physical data, a wireless network is not allowed to be used, and data transmission is not allowed to be performed by using any network equipment, so that the traditional internet technology cannot provide service for the court.
In the prior art, data communication between internal and external networks of government offices such as court needs to be carried out specially, and then data communication is carried out through a network gate. The network Gate (GAP) is called a safety isolation network gate, and is a network safety device which is connected by a link layer between networks and is cut off on a circuit by special hardware with various control functions and can exchange application data with proper safety between the networks. However, the single data communication realized by the gatekeeper method still needs physical network connection, and the process is complicated.
Therefore, how to transmit intranet and extranet data more safely and conveniently becomes a technical problem to be solved by those skilled in the art.

Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments that can be derived from the embodiments given herein by a person of ordinary skill in the art are intended to be within the scope of the present disclosure.
In the embodiment of the application, a corresponding solution is provided for the problem of data transmission between an internal network and an external network. In the embodiment of the present application, the intranet may specifically refer to a network environment isolated from the internet and unable to access the internet, for example, a local area network, which is usually implemented in a limited area range such as a government organization and isolated from the outside, and is therefore referred to as an "intranet"; "extranet" generally corresponds to "intranet" and broadly refers to various network environments that have access to the internet. In the scheme, a client program for data transmission can be provided, and the data transmission between different network environments is realized by taking the graphic code as a medium. The client program may specifically be a client installed on a PC side of a computer or the like, or may also exist in the form of a web, and the like. When data transmission is required, the client programs may be respectively run on devices of an intranet and an extranet, and for convenience of description, the client program running on a first terminal device of a sender is referred to as a first client, and the client running on a second terminal device of a receiver is referred to as a second client. Of course, the client functions are only divided from the perspective of different roles played in the same transmission process, and in practical applications, the same client program may have the functions of the first client and the second client at the same time, and may play different roles in different data transmission processes. That is, assuming that data transmission is required between a first terminal device in a first network environment (intranet or extranet) and a second terminal device in a second network environment (extranet or intranet), the client program may be run on the first terminal device and the second terminal device, respectively. Also, the second terminal device may be carried into the spatial environment of the first terminal device, e.g. in the same house, the two terminal devices may be placed face to face, etc. However, in the embodiment of the present application, there is no need to perform physical connection or network connection between two terminal devices. After the preparation work is done, the file to be transmitted stored in the first terminal device can be input to the first client, and the first client can process the file to be transmitted to generate one or more graphic codes. In this way, the second terminal device as the receiving party can receive the data by scanning the graphic code, and then the second client restores the received data to a file.
Therefore, the scheme provided by the embodiment of the application utilizes the characteristic that the graphic code can carry data and can realize data transmission in a code scanning mode, and provides a scheme for data transmission between an internal network and an external network. Through the scheme, when data transmission is required to be carried out between an internal network and an external network, devices such as a gateway and the like are not required to be used, physical connection or network connection is not required to be established between terminal devices between different network environments, and data transmission can be achieved. It should be noted that, in the embodiment of the present application, the data transmitted between the intranet and the extranet may be specially batched data passing through relevant departments, and the problem of data leakage in the intranet is not involved. For example, as shown in fig. 1, a department such as a court needs to issue a piece of information about a legal vehicle through a commodity object information service system, but the information about the vehicle is stored in an intranet system of the court, and in order to be able to transmit the information to the commodity object information service system, the information may be sent to the relevant department in advance for a special lot, and then data transmission from the intranet to the extranet is realized through the scheme of the embodiment of the present application. That is, the second terminal device of the external network may be carried into the court, for example, may be placed in the same room as the first terminal device of the internal network, and so on. The method comprises the steps that a first terminal device of an intranet converts a file to be transmitted into one or more graphic codes through a first installed client, a second terminal device of an extranet can receive data in a code scanning mode through the graphic codes, and then the graphic codes are restored into the file. Or, the consumer user in the commodity object information service system wants to purchase a legal vehicle, and due to its particularity, the court may need to acquire the information of the consumer user before the transaction is specifically achieved, and at this time, the information needs to be transferred to the system inside the court. For the situation, the special approval can be carried out on the specific relevant departments of the court, and then, the data transmission from the external network to the internal network is realized through the scheme provided by the embodiment of the application, and the like.
The following describes in detail a specific technical solution provided in an embodiment of the present application.
Example one
First, the first embodiment provides a data transmission system between an internal network and an external network, and referring to fig. 2, the system may specifically include:
the first client 201 is configured to operate in a first terminal device in a first network environment, generate at least one graphic code according to a received file to be transmitted, and display the graphic code in an associated display screen;
the second client 202 is configured to operate in a second terminal device in a second network environment, receive data in a manner that a code scanning device associated with the second terminal device scans a code of the graphic code, and perform file restoration on the received data according to file format information carried in the graphic code;
the first terminal device and the second terminal device are located in the same physical space.
The first network environment or the second network environment may be a network environment isolated from the internet, that is, the first network environment or the second network environment cannot be connected to the internet, and therefore, data transmission cannot be performed between the first terminal device and the second terminal device by using a network connection method.
As described above, if data transmission is required between a first terminal device in a first network environment and a second terminal device in a second network environment, the following preparation work may be performed first: the client programs passed by the embodiments of the present application are installed in the first terminal device and the second terminal device, or the web pages provided by the embodiments of the present application are opened by using a browser or the like, respectively. Of course, for a terminal device in an intranet environment such as a court of law, since the terminal device cannot be connected to a public network, the relevant functions of the client may not be obtained by means of a web page, and at this time, the terminal device may be implemented by installing a local client program. In addition, the second terminal device can be carried to the space environment where the first terminal device is located, so that a camera and other devices of the second terminal device can scan the display screen of the first terminal device.
After the preparation work is completed, specific data transmission can be performed, and at this time, information of the file to be transmitted can be provided to the first client by dragging the related file to be transmitted to an input box of the first client and the like. And then, the first client can process the file to be transmitted to generate at least one graphic code. The specific graphic code may include a bar code, a two-dimensional code, and the like. The two-dimensional code can carry a larger amount of information, so that the two-dimensional code is mainly used, and can be expressed by a graphic code with a higher dimensionality. In the two-dimensional code technology, the concept of '0' and '1' bit streams forming the internal logic basis of a computer is utilized in code compilation, a plurality of geometric shapes corresponding to binary systems are used for representing character numerical value information, and automatic identification and reading can be realized through image input equipment or photoelectric scanning equipment so as to realize automatic information processing. Therefore, when the first client processes the file to be transmitted, the file to be transmitted can be firstly converted into binary data, and then at least one two-dimensional code is generated according to the binary code. Then, the second client can receive data in a code scanning mode, wherein the data can carry information such as file types, and then the files can be restored according to the file format information.
The reason why a plurality of two-dimensional codes may be generated is that the information capacity of one two-dimensional code is limited, and if the information amount of a file to be transmitted converted into a binary code exceeds the maximum information amount that one two-dimensional code can accommodate, the binary code needs to be split and expressed by a plurality of two-dimensional codes. In this case, in the process of generating the graphic code, a sequence identifier, such as a number, may also be added to the graphic code. In this way, after the second client decodes the plurality of graphic codes respectively, the obtained decoding results can be spliced according to the sequence identifier, and the splicing results are restored to the target file according to the specific file format information. In addition, under the condition of generating the plurality of graphic codes, the first client may sequentially generate and display the plurality of graphic codes, and each graphic code stays in the display screen of the first terminal device for a preset time length. That is to say, after each graphic code is generated, the graphic code can be displayed in the display screen of the first terminal device and stays for a certain time length for the second terminal device to complete code scanning, and then, the next graphic code is automatically displayed.
Certainly, in the specific implementation, if the specific splitting is performed to have too many graphic codes, the transmission efficiency may be affected, and therefore, in this embodiment of the application, under the condition of expression by using the two-dimensional code, the two-dimensional code may also be implemented in a full-screen two-dimensional code manner, that is, the two-dimensional code occupies the entire screen of the display screen of the first terminal device, so as to improve the information capacity of the two-dimensional code to the maximum extent. During specific implementation, the first client may further obtain parameter information of a display screen associated with the first terminal device, and then generate the full-screen two-dimensional code according to the parameter information, where the parameter information of the display screen includes information of a size and a resolution of the display screen. Specifically, the first client may determine the maximum information amount that the same full-screen two-dimensional code can bear according to the parameter information, and if the information amount of the binary code corresponding to the file to be transmitted is greater than the maximum information amount, the binary code corresponding to the file to be transmitted is divided according to the maximum information amount to obtain multiple binary codes, and corresponding full-screen two-dimensional codes are generated for each binary code respectively.
That is to say, the information capacity of the full-screen two-dimensional code is related to the display screen parameters of the first terminal device, the larger the size of the display screen is, the higher the resolution ratio is, the larger the information capacity of the full-screen two-dimensional code is, and for the same file to be transmitted, the smaller the number of the full-screen two-dimensional codes required to be used is. For example, for a file to be transmitted, if a display screen with 1024 × 768 resolution is used, the file may need to be split into 10 full-screen two-dimensional codes to complete transmission, and if a display screen with 4K resolution is used, only one full-screen two-dimensional code may be needed, which may further improve efficiency.
Therefore, in the above manner, if a file in a first terminal device in a first network environment needs to be transmitted to a second terminal device in a second network environment, only the client program described in the embodiment of the present application needs to be run in the first terminal device and the second terminal device, accordingly, the first client of the sender can convert the file to be transmitted into at least one graphic code, the second client of the receiver can obtain specific data by scanning and decoding the graphic code, and then restore the file according to information such as a specific file format. For example, if the file to be transmitted is a table file in xlsx format, the second client may restore the specific data to the table file in xlsx format, and so on. Therefore, by the mode, data transmission can be realized without physical connection between devices in different network environments or wired or wireless network connection, and the method is convenient and fast. In addition, as the transmission process does not involve hardware connection and wired or wireless network connection, the safety of the transmission process can be ensured.
Example two
The second embodiment provides a data transmission method between the internal network and the external network from the perspective of the first client described in the first embodiment, that is, as a sender of a file, a specific file to be transmitted can be converted into one or more graphic codes, and the graphic codes are used to carry specific file data, so that a receiver can receive data in a code scanning manner and then restore the data to the file. Specifically, referring to fig. 3, the method may specifically include:
s301: determining a file to be transmitted in first terminal equipment in a first network environment;
for example, if the first network environment is an internal network environment of an organization unit such as a court, the specific file to be transmitted may be a file that is specially approved by a relevant department and is allowed to be transmitted to the second terminal device in the second network environment. In specific implementation, the first client may provide an operation option or a drag frame for receiving a file to be transmitted, and when a certain file needs to be transmitted, the file may be selected through the operation option or the drag frame.
S302: generating at least one graphic code according to the file to be transmitted, displaying the graphic code in an associated display screen, so that second terminal equipment in a second network environment can receive data in a code scanning mode of the graphic code, and restoring the received data according to file format information carried in the graphic code;
the first terminal device and the second terminal device are located in the same physical space.
In specific implementation, the graphic codes include two-dimensional codes, and specifically, when at least one graphic code is generated according to the file to be transmitted, the file to be transmitted can be converted into a binary code, and at least one two-dimensional code is generated according to the binary code.
Because the information capacity of the same two-dimensional code is limited and the information capacity is influenced by the size of the two-dimensional code, the two-dimensional code can comprise a full-screen two-dimensional code in order to reduce the number of the required two-dimensional codes; at this time, when at least one two-dimensional code is generated according to the binary code, parameter information of a display screen associated with the first terminal device may be obtained, where the parameter information of the display screen includes information of a size and a resolution of the display screen; and then, generating the full-screen two-dimensional code according to the parameter information.
Specifically, when a full-screen two-dimensional code is generated, the maximum information quantity which can be borne by the same full-screen two-dimensional code can be determined according to the parameter information; if the information quantity of the binary code corresponding to the file to be transmitted is larger than the maximum information quantity, the binary code corresponding to the file to be transmitted is divided according to the maximum information quantity to obtain multiple binary codes; and respectively generating corresponding full-screen two-dimensional codes for each binary code.
In addition, when the graphic codes are multiple, a sequence identifier can be added to the graphic codes, so that decoding results corresponding to the multiple graphic codes can be spliced according to the sequence identifier.
In order to facilitate the second terminal device to scan codes, the plurality of graphic codes can be sequentially displayed when the number of the graphic codes is multiple, and each graphic code stays in the display screen of the first terminal device for a preset time length.
EXAMPLE III
The third embodiment provides a data transmission method between the internal network and the external network from the perspective of the second client in the first embodiment, that is, for the receiver side, the data can be received by scanning the graphic code, and then the graphic code is restored to the file. Specifically, referring to fig. 4, the method may specifically include:
s401: scanning a graphic code generated in first terminal equipment in a first network environment through code scanning equipment associated with second terminal equipment to acquire information of the graphic code, wherein the graphic code is generated according to a file to be transmitted in the first terminal equipment;
s402: decoding the graphic code to obtain corresponding file data and file format information;
s403: restoring the file data into the file to be transmitted according to the file format information;
the first terminal device and the second terminal device are located in the same physical space.
If the number of the graphic codes is multiple, the graphic codes can be scanned in sequence, and the decoding results of the graphic codes are spliced according to the sequence identification carried in the graphic codes so as to restore the file.
