The B/S architecture enables a user to realize corresponding business operation through a browser without downloading a client. Particularly in the field of smart cards, users can realize information input and authority distribution of the smart cards through webpage operation.
Most of the existing browsers need to embed an ActiveX control to enable users to interact with the smart card through the browser. However, the embedded actigraphy control of the browser may bring a certain security risk to the user, and as the browser is continuously updated and iterated, the embedded actigraphy control is gradually optimized, and the browser gradually does not support the embedded actigraphy control, so that the user needs to interact with the smart card again through the client. The incompatibility of the browser and the interaction of the downloading client bring a plurality of inconveniences to the user, so that the card reading process of the user is complex, the use experience of the user is reduced, and the workload of research and development personnel is improved.
In order to solve the above problems, the embodiment of the application provides a card reading method of a card service system, which enables a user to read a smart card from a webpage end by calling a dynamic library without downloading a client and embedding an ActiveX control, thereby greatly improving card reading efficiency of the smart card and optimizing use experience of the user.

The dynamic library is a shared library, and is an executable file, and all processes can share or reference the content in the dynamic library.
The dynamic library comprises a plurality of functions which can be directly called, and has wide application range and exists in most intelligent terminals. In embodiments of the present application, a card reading function may be included in the dynamic library. When receiving the card reading request, the card reading function in the dynamic library can be directly called to realize the reading of the smart card.
In the embodiment of the application, the card reading module can start the HTTP service of the designated port to monitor whether the card reading request sent by the card application module is received.
Specifically, after receiving the card reading request sent by the card service application module, the card reading module can call the dynamic library by using the VB to refer to the dynamic library so as to read the card information of the smart card through the card reader.

After the card information of the smart card is obtained, the card information is analyzed, and the card number of the target smart card is intercepted from the card information. After the card number of the target smart card is obtained, the card number can be packaged, and the packaged card number is returned to the card service application module, so that the card service application module outputs the card number of the target smart card.
After the card number is output by the Web browser, the card application module can facilitate the user to perform related business operations according to the displayed card number, for example, permission change, information input or other business operations on the target smart card according to the card number.

And the card reading module calls the dynamic library after receiving the card reading request so as to realize serial port communication with the card reader, reads the card through the card reader and receives card information of the target smart card fed back from the card reader.
After receiving the card information, the card reading module analyzes the parameters of the card information to obtain the card number of the target smart card, encapsulates the card number and feeds back the card number to the card application module.
And after receiving the card number sent by the card reading module, the card application module displays the target smart card number to the user at an interface of the Web browser so that the user performs business operations such as authority allocation or information input on the target smart card. Wherein, the card number can be 8 bits.

In some embodiments of the present application, invoking the dynamic library upon receipt of a card read request includes:
detecting whether the card reading request is valid or not when the card reading request is received;
when the card reading request is valid, the dynamic library is invoked.
Optionally, when the card reading module receives the card reading request sent by the card service application module, the card reader can be identified whether the target smart card is placed or not so as to detect whether the card reading request is valid or not.
Specifically, when the card reader is identified as not placing the target smart card, the card reading request is judged to be invalid, and the dynamic library can not be called. When the smart card is identified to be placed on the target smart card, the validity of the card reading request is judged, and a dynamic library can be called.
The card reading module and the card reader can perform serial communication.
Illustratively, the card reading process may be as follows:
first, it is determined whether it is a cross-domain snoop request: httprequest.httpremethod.toupper () = "OPTIONS".
If so, code 200 is returned.
Then, it is judged whether the parameter action satisfies the condition: request.query string ("action") = "ReadCard".
And if the condition is met, performing card reading operation.
According to the method and the device for reading the card, whether the card reading request is effective is detected, invalid card reading requests can be avoided, the frequency of calling the dynamic library is reduced, and the card reading flow is optimized.
In some embodiments of the present application, the dynamic library includes a card reading function, calls the dynamic library, and reads card information of the target smart card through the dynamic library, including:
and calling a card reading function in the dynamic library, and reading card information of the target smart card through the card reading function.

In some embodiments of the present application, when the card information of the target smart card is read by the card reading function, the card reading method further includes:
judging whether the card reading function is successful;
and outputting a card reading failure signal when the card reading function is unsuccessful.
In the embodiment of the application, whether the card reading is successful can be judged through the return value of the card reading function.
Specifically, when the card reading function returns card information, the card reading success of the card reading function is judged. When the card reading function returns the card reading failure identifier, the card reading function is judged to be unsuccessful in card reading, and a card reading failure signal is output to remind a user of the card reading failure, so that the user can check conveniently, and invalid card reading is avoided.
Optionally, when the card reading function fails to read the card, the card reading module may output a card reading failure signal to the card service application module, for example, a text frame flick prompt of "card reading failure, please check" or "card reading failure this time, please read the card again". Or when the card reading function is unsuccessful, the card reading module can output a voice prompt of 'please read the card again' through the card service application module.
For example, the process of determining whether a card is successfully read may be as follows:
and calling a readCardSerNum function of a third-party dynamic library to judge the return value, and judging that the card reading is successful if the return value is 8 bits.
According to the embodiment of the application, the reliability of card reading can be improved by judging whether the card reading function is successful.

when the serial port is in an initialized state, the dynamic library is called, and card information of the target smart card is read through the dynamic library.
In the embodiment of the application, the card reading module is connected with the card reader through the serial port to perform information interaction.
Optionally, when the card reading module detects that the serial port is not in the initialized state, it indicates that the connection between the card reading module and the card reader is abnormal, and at this time, the card reading module may output an initialized abnormal signal, such as a voice prompt or a text frame such as "serial port is abnormal" or "serial port connection error", to the card service application module.
When the serial port is detected to be in an initialized state, a card reading function in the dynamic library is called, and card information of the target smart card is read through the card reading function.
Fig. 4 is a flowchart illustrating another implementation of a card reading method according to an embodiment of the present application, and as shown in fig. 4, a card reading process is as follows:
after card reading is started, judging whether the serial port is in an initialized state;
if not, outputting an initialization abnormal signal;
if yes, calling a card reading function in the dynamic library to read the card.
Judging whether the card reading is successful;
if not, outputting a card reading failure signal;
if yes, reading card information of the target smart card, and returning an 8-bit card number.
Finally, after the card is successfully read, the encapsulated data is returned and ended.
According to the method and the device for reading the intelligent card, whether serial port initialization is successful or not and whether card reading is successful or not is judged, the intelligent card reading flow is optimized, and card reading efficiency is improved.
In some embodiments of the present application, before detecting whether a card reading request is received, the card reading method further includes:
acquiring a serial port of the card service system, and detecting the state of the serial port, wherein the state comprises a normal state and an abnormal state;
outputting a serial port abnormal signal when the serial port is in an abnormal state;

In the embodiment of the application, the serial port is a serial port in an intelligent terminal where the card service system is located.
The card reading module can test whether the serial port can be communicated or not by calling a test function in the dynamic library so as to judge the state of the serial port. Wherein the test function may be a SendBeep function.
When the serial port is tested to be capable of being connected by using the test function, the serial port is judged to be in a normal state, and the serial port is marked to be in an initialized state.
When the serial port is tested to be unable to be passed by using the test function, the serial port is judged to be in an abnormal state, and a serial port abnormal signal is output so as to prompt the user that the current serial port is initialized to be failed and avoid the invalid card reading of the user.
For example, when the card reading module detects that the serial port is in an abnormal state, the card reading module may output a serial port abnormal signal, such as a "serial port initialization abnormal" voice prompt or a text box to the card application module.
Specifically, fig. 5 is a flowchart for implementing serial port initialization according to the embodiment of the present application, where the serial port initialization process is as follows:
firstly, information of all serial ports of the intelligent terminal where the card service system is located is obtained.
Secondly, traversing all serial ports.
And finally, calling a SendBeep function, and judging whether the serial port is successfully initialized by judging whether the serial port can be completely initialized.
If yes, the serial port number of the current serial port is cached, and the serial port is marked as an initialization state.
If not, outputting a serial port abnormal signal.
According to the method and the device for detecting the serial port initialization, whether the serial port initialization is normal or not is detected by calling the test function in the dynamic library, the problem that the serial port error causes invalid card reading can be effectively avoided, the card reading flow is optimized, and the card reading reliability is improved.
The card reading method of the embodiment of the application can be as follows:
