Detailed Description
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 only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative work belong to the protection scope of the present invention.
In order that those skilled in the art will better understand the disclosure, the invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Next, a system for implementing a virtual electronic card communication according to an embodiment of the present invention will be described in detail. Fig. 1 is a schematic structural diagram of a system for implementing virtual electronic card communication according to an embodiment of the present invention, including an upper computer 1 and a client 2; the client 2 is provided with a virtual electronic card 21 and a virtual card reader 22 supporting socket communication.
The dummy electronic card 21 may be a dummy IC card. The virtual electronic card 21 is based on a socket protocol to realize communication, and thus a device accessing the virtual electronic card 21 needs to support the socket protocol. However, in practical applications, many devices often do not support the socket protocol, and in the embodiment of the present invention, for convenience of description, the devices that do not support the socket protocol may be collectively referred to as the upper computer 1.
In order to realize the access of the upper computer 1 to the virtual electronic card 21, in the embodiment of the present invention, a virtual card reader 22 is disposed on the client 2 where the virtual electronic card 21 is located.
The virtual reader 22 may emulate the functionality of a reader through a software program. The virtual card reader 22 may implement communication with the upper computer 1, or may implement interaction with the virtual electronic card 21 based on a socket protocol.
When the administrator needs to access the virtual electronic card 21 through the upper computer 1, the administrator can input a card operation instruction on a user interface provided by the upper computer 1.
The card operation command includes specific operations to be performed by the virtual electronic card, such as storing and reading data on the virtual electronic card.
In a specific implementation, the virtual card reader 22 is in communication connection with the upper computer 1 and is used for receiving a card operation instruction transmitted by the upper computer 1; and transmits the card operation instruction to the virtual electronic card 21 based on the socket communication protocol.
And the virtual electronic card 21 is used for executing corresponding operation according to the received card operation instruction, and feeding back an operation result to the virtual card reader 22 based on the socket communication protocol. When the virtual card reader 22 receives the operation result fed back by the virtual electronic card 21, the operation result can be transmitted to the upper computer 1.
The virtual card reader 22 can be regarded as a bridge for communication between the upper computer 1 and the virtual electronic card 21, and the virtual card reader 22 can forward a card operation instruction transmitted by the upper computer 1 to the virtual electronic card 21 and also can forward an operation result fed back by the virtual electronic card 21 to the upper computer 1.
In practical applications, the connection between the virtual electronic card 21 and the virtual card reader 22 may be maintained at all times, or the connection between the virtual card reader 22 and the virtual electronic card 21 may be established in case of an operation requirement.
Taking the establishment of the connection when there is an operation demand as an example, specifically, the virtual card reader 22 may establish the connection with the virtual electronic card 21 based on the socket communication protocol after receiving the card operation instruction transmitted by the upper computer 1.
In order to reduce the occupation of system resources by the socket connection, the virtual card reader 22 may disconnect the virtual electronic card 21 after receiving the operation result fed back by the virtual electronic card 21.
Considering that the access to the virtual electronic card 21 may still need to be performed in a short time after the upper computer 1 completes the access to the virtual electronic card 21, and if the connection is repeatedly established, it takes a long time, therefore, in the embodiment of the present invention, after receiving the operation result fed back by the virtual electronic card 21, the virtual card reader 22 may determine whether the operation instruction is received within the preset time.
The value of the preset time can be set according to actual requirements, and is not limited herein.
When the virtual card reader 22 does not receive the operation instruction within the preset time, it indicates that there is no interaction between the virtual card reader 22 and the virtual electronic card 21 in a short time, and at this time, the virtual card reader 22 may disconnect the connection with the virtual electronic card 21, thereby releasing the resources occupied by the connection.
The access of the virtual electronic card 21 involves the transmission of data and instructions, and in an embodiment of the present invention, a local port may be created when the virtual card reader 22 is built to enable the interaction of the virtual card reader 22 with the virtual electronic card 21. Specifically, the virtual card reader 22 may transmit card operating instructions to the virtual electronic card 21 through the local port.
According to the technical scheme, the system for realizing the communication of the virtual electronic card comprises an upper computer and a client; the client is provided with a virtual electronic card and a virtual card reader supporting socket communication. The virtual card reader is in communication connection with the upper computer, when the upper computer needs to operate the virtual electronic card on the client, a card operation instruction can be issued to the virtual card reader of the client, and the virtual card reader transmits the card operation instruction to the virtual electronic card based on a socket communication protocol. The virtual electronic card can execute corresponding operation according to the received card operation instruction, and feeds back an operation result to the virtual card reader based on the socket communication protocol. And after the virtual card reader receives the operation result fed back by the virtual electronic card, the operation result can be transmitted to the upper computer. By arranging the virtual card reader supporting socket communication on the local client, interaction with an upper computer can be realized, and access to the virtual electronic card only supporting socket communication can be realized. The virtual card reader is equivalent to a transfer component, access of the upper computer to the virtual electronic card is achieved, the problem that the upper computer can only access the virtual electronic card by supporting socket communication is effectively solved, and the universality of the virtual electronic card is improved. In order to facilitate the manager to intuitively know the operation result fed back by the virtual electronic card 21, the upper computer 1 may display the operation result through the user interface after receiving the operation result transmitted by the virtual card reader 22.
In practical application, corresponding virtual electronic cards 21 can be set according to different business requirements, and in order to facilitate the access of the upper computer 1 to each virtual electronic card 21, a corresponding virtual card reader 22 can be set for each virtual electronic card 21. Therefore, a plurality of sets of virtual electronic cards 21 and virtual card readers 22 may be provided on the client 2; each virtual card reader 22 has its corresponding one of the virtual electronic cards 21.
By arranging a plurality of groups of virtual electronic cards and virtual card readers on the client, different service requirements can be met, and service functions of the client are greatly enriched.
