In order to more clearly and completely describe the technical solutions in the embodiments of the present application, the technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. 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 application.
The embodiment of the application provides a data card reading and writing method.
Referring to fig. 2, fig. 2 is a schematic flow chart of a data card reading and writing method provided in the present application, where the data card reading and writing method is applied to a server and may include:
s101: acquiring data card state information from a client according to a data card operation command;
the method comprises the steps of obtaining data card state information, wherein the data card state information is the current state of the data card and comprises a card to be written state and a card to be read state, the card to be written state indicates that the data card needs to be written currently, and the card to be read state indicates that the data card needs to be read currently.
In the embodiment of the present application, the data card is also called an electronic data card, and can support reading and writing of electronic data, for example, the data card includes, but is not limited to, a magnetic card, a barcode card, an Integrated Circuit (IC) card, and an Identification (ID) card.
In some embodiments, when the server receives a data card operation command, the server may obtain data card status information from a client according to the data card operation command, where the client is a local client directly connected to a card reader and may be connected to the server to implement data communication; the server is connected to the client through a network, which may be a local area network or a wide area network, and may be an internet network (e.g., an edge network, a cloud network, etc.). When the server is connected with the client through the internet, the server is a remote server at the moment, and the data card reading and writing are realized based on the remote connection. For example, in a cash register system, a local client is connected with a remote server to implement read-write operation of an IC card, and the remote server can obtain state information of the IC card from the local client when receiving a data card operation command, and then implement read-write operation of the IC card according to the state information. In some embodiments, the remote server may also be operated by the remote client, so as to affect the read-write process of the data card.
The data card operation command is used to notify the server that the data card needs to be read and written, and of course, whether the read operation or the write operation is determined by the server is not determined, and the determination needs to be further performed by acquiring the state information of the data card.
It should be noted that the client related to the embodiments of the present application may be provided by a terminal device, and the server related to the embodiments of the present application may be provided by a server. The server may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing basic cloud computing services such as cloud service, a cloud database, cloud computing, a cloud function, cloud storage, Network service, cloud communication, middleware service, domain name service, security service, Content Delivery Network (CDN), big data and an artificial intelligence platform. The terminal device may be, but is not limited to, a smart phone, a tablet computer, a notebook computer, a desktop computer, a smart speaker, a smart watch, and the like. The terminal device and the server may be directly or indirectly connected through wired or wireless communication, and the embodiment of the present application is not limited.
In an embodiment of the application, the acquiring of the data card status information from the client according to the data card operation command may include: reading and obtaining data card state information from a second storage directory of the client according to the data card operation command; the data card state information is obtained by the client end through reading from the data card after receiving the data card connection information.
The embodiment of the application provides an implementation method for reading data card state information, namely, a server reads a local storage of a client, namely the second storage directory, so as to obtain the data card state information. When the client senses the data card connection information, that is, when it senses that a data card is inserted (or connected), the client reads the information of the data card to determine the state of the data card, for example, if the data card is an empty card, it indicates that the data card is in a card writing state, and if the data card is not an empty card, it indicates that the data card is in a card reading state, so that after the data card state information is obtained, the data card state information can be stored in a local second storage directory for the server to read.
Of course, the second storage directory is only an implementation manner for storing the data card status information provided in the preferred embodiment, and is not unique, and any storage medium may be selected to implement storage of the data card status information, which is not limited in this application.
In an embodiment of the application, before obtaining the data card status information from the client according to the data card operation command, the method may further include: and receiving a data card operation command sent by the client based on the data card connection information.
The embodiment of the application provides a method for acquiring a data card operating command, namely, the data card operating command can be sent to a server by a client, so that the server can acquire data card state information based on the data card operating command. As described above, after the client senses the data card connection information, the client may determine the data card status information by reading the data card and store the data card status information in the second storage directory, and based on this, may simultaneously initiate a data card operation command to the server to notify the server of acquiring the data card status information.
In an embodiment of the application, before obtaining the data card status information from the local client according to the data card operation command, the method may further include: and responding to the data card operation command according to a preset time interval.
The embodiment of the application provides another method for acquiring the data card operating command, which can set a timing mechanism for the server, so that the server can respond to the data card operating command according to a preset time interval, and further acquire the state information of the data card. The specific value of the preset time interval does not affect the implementation of the technical scheme, and the specific value is set by a technician according to the actual situation, which is not limited by the application.
It can be understood that, the two implementation manners may be set by a skilled person according to an actual requirement, or may be set simultaneously, which is not limited in this application.
S102: when the data card state information is a card to be written, acquiring target data, and sending the target data to a client so that the client writes the target data into the data card;
this step is intended to implement the write operation of the data card. When the data card state information is the card to be written, the server side can acquire target data (namely data information needing to be written into the data card) and send the target data to the client side; further, the client can send the target data to the data card, and the data card writing operation based on the client is realized. The implementation process of the server acquiring the target data may include: the server initiates a data acquisition request to a corresponding client (namely, a remote client) based on the data card state information, the remote client displays prompt information for requesting to acquire target data on a front-end interface, so that a technician can input the target data on the front-end interface according to the prompt information and feed the target data back to the server by the remote client, and therefore, the target data is acquired at the server. For example, the target data includes, but is not limited to, user information, financial information, and rights information associated with the data card.
S103: when the state information of the data card is the card to be read, reading a first storage directory of the client to obtain read data; and the read data is obtained by reading the data card by the client.
This step is intended to enable a read operation of the data card. As described above, after the client senses the data card connection information, the client may determine the data card status information by reading the data card and store the data card status information in the second storage directory, and meanwhile, when the data card status information is the card to be read, the client may simultaneously read the data information stored in the data card, obtain the read data, and locally store the read data, that is, store the read data in the first storage directory. Therefore, when the state information of the data card is the card to be read, the server side can directly read the first storage directory of the client side to obtain the read data of the data card. Of course, the first storage directory and the second storage directory may be the same storage directory or different storage directories, which is not limited in this application. After the server side obtains the read data, the read data can be stored to a specific storage location, such as a database or a block chain, and corresponding services, such as banking services, can also be executed according to the read data.
In an embodiment of the application, after obtaining the read data, the reading the first storage directory of the client further includes: and sending a data reading success instruction to the client so that the client modifies the state information of the data card according to the data reading success instruction.
The data card reading and writing method provided by the embodiment of the application aims to realize the updating function of the state information of the data card. After the server side obtains the read data, a data reading success instruction can be sent to the client side, and therefore the client side can modify the state information of the data card from the card to be read to the card reading success according to the data reading success instruction. Certainly, when the server side reads the client side and fails to obtain the read data, a data reading failure instruction can be fed back to the client side, and therefore the client side can modify the state information of the data card from the card to be read into card reading failure according to the data reading failure instruction, and technicians can obtain the data reading result of the data card in time. In addition, under the condition of card reading failure, the client can further output a card reading failure prompt so that technicians can trace the source of the abnormality in time.
Therefore, according to the data card reading and writing method provided by the application, the server side is connected with the client side, when the data card needs to be written, the server side sends the target data to the client side, and the client side writes the target data into the data card; when the data card needs to be read, the client side directly reads the data card to obtain read data, and local storage is performed, so that the server side can directly read the local storage of the client side to obtain the read data. Therefore, the read-write operation of the data card is directly realized based on the local client, and the data card read-write operation is not required to be carried out by opening a remote computer port, so that the read-write efficiency of the data card is effectively improved, and the user experience is further improved.
The embodiment of the application provides another data card reading and writing method.
Referring to fig. 3, fig. 3 is a schematic flow chart of a data card reading and writing method provided in the present application, where the data card reading and writing method is applied to a client and may include:
s201: when receiving the data card connection information, acquiring the data card state information;
this step is intended to achieve the acquisition of data card status information. When the client senses the connection information of the data card, namely senses the insertion (connection) of the data card, the client can read the information of the data card to determine the state of the data card, so that the state information of the data card is obtained. Furthermore, the client can locally store the state information of the data card for the server to read, and then perform corresponding read-write operation on the data card.
S202: when the state information of the data card is the card to be read, reading the data card to obtain read data, and storing the read data into a first storage directory for a server to read;
this step is intended to enable a read operation of the data card. When the data card state information is the card to be read, the client can directly read the data card to obtain corresponding read data, and locally store the read data, namely store the read data in the first storage directory for the server to read.
S203: and when the state information of the data card is the card to be written, writing the target data into the data card under the condition of receiving the target data sent by the server.
This step is intended to implement the write operation of the data card. When the data card state information is the card to be written, the server side sends target data to the client side according to the data card state information, the target data is the data needing to be written into the data card, therefore, the client side can write the received target data into the data card, and therefore writing operation on the data card is completed.
In an embodiment of the application, the writing the target data into the data card may include: writing the target data into the data card through a preset reading and writing tool; the obtaining of the read data by the read data card may include: and reading the data card by a preset reading and writing tool to obtain read data. For example, the client may store a preset read/write tool, which operates a serial interface (SerialPort) to read and write data.
It can be understood that the data card read-write method provided by the embodiment of the application aims to realize the read-write operation of the data card through the client, and when the data card is read-write operated through the client, the read-write tool preset at the client can be specifically used for performing the read-write operation on the data card, so that when the data card is written, the preset read-write tool is operated to write target data into the data card; when the data card is read, the data card can be read by operating a preset reading and writing tool to obtain read data. Of course, the setting and updating of the data card status information at the client may also be implemented by the preset read-write tool.
The client can establish a shared folder to store the preset read-write tool in the shared folder, and further, the client can realize the operation of the preset read-write tool through the corresponding plug-in. In addition, the data card state information acquired by the client and the read data acquired when the data card is read can be respectively stored in different storage directories in the shared folder.
It should be noted that the preset read/write tool integrates two functions of reading and writing at the same time, but in some embodiments, the preset read/write tool may be subdivided into a preset read tool and a preset write tool, where the preset read tool is dedicated to the function of reading data, and the preset write tool is dedicated to the function of writing data.
In an embodiment of the application, after writing the target data into the data card, the method may further include: acquiring a data writing result fed back by the data card; and modifying the state information of the data card according to the data writing result.
The data card reading and writing method provided by the embodiment of the application can realize the updating function of the state information of the data card. After writing the target data into the data card, the data card will feed back the result of the write data to the client, such as a successful card write or a failed card write. Therefore, the client can modify the state information of the data card according to the data writing result, when the data writing result is the card writing failure, the state information of the data card can be changed from the card to be written to the card writing failure, and when the data writing result is the card writing success, the state information of the data card can be changed from the card to be written to the card writing success, so that a technician can timely know the data writing result of the data card. In addition, under the condition of card writing failure, the client can further output a card writing failure prompt so that technicians can trace the source of the abnormality in time.
Therefore, according to the data card reading and writing method provided by the application, the server side is connected with the client side, when the data card needs to be written, the server side sends the target data to the client side, and the client side writes the target data into the data card; when the data card needs to be read, the client side directly reads the data card to obtain read data, and local storage is performed, so that the server side can directly read the local storage of the client side to obtain the read data. Therefore, the read-write operation of the data card is directly realized based on the local client, and the data card read-write operation is not required to be carried out by opening a remote computer port, so that the read-write efficiency of the data card is effectively improved, and the user experience is further improved.
Based on the above embodiments, taking an IC card as an example, the present application provides an IC card read-write method.
Referring to fig. 4 and fig. 5, fig. 4 is a read-write flow chart of an IC card provided in the present application, where a server is a remote server (for example, a server of a cash register system), and a client is a local client (for example, a client of the cash register system); fig. 5 is a timing chart of an IC card read/write method provided in the present application, in which an S-disk sharing folder is installed in a local client, and the local client is remotely connected to a server (remote server).
For example, when a retail POS is remotely connected, a shared folder may be added at a local client, and a tool (a preset read/write tool) for reading and writing an IC card is provided in the shared folder and serves as a bridge between a cash register system and a card reader, on this basis, the IC card read/write method is implemented as follows:
(1) all parameter information (parameter information of serial ports for inserting the IC card) is written into a configuration file \ \ tsclient \ s \ SerialPort \ setting. The 'SerialPort' directory is manually created in advance, and in the actual operation process, the client plug-in is automatically created; ini is the configuration file name.
(2) The read/write tool is transferred to the \ \ tsclient \ s \ SerialPort directory (the storage directory for storing the read/write tool, which may be considered a third storage directory).
