Detailed Description
The following detailed description of embodiments of the present invention is provided in connection with the accompanying drawings and examples. The following examples are intended to illustrate the invention but are not intended to limit the scope of the invention.
Fig. 1 is a flowchart of a two-dimensional code data acquiring method according to an embodiment of the present invention, as shown in fig. 1, the method includes: 101. setting a system keyboard hook in an upper computer program, wherein the system keyboard hook is used for monitoring all key information; 102. identifying each piece of simulation key information corresponding to the two-dimensional code acquired by the scanning gun based on the key information; 103. analyzing each piece of simulation key information corresponding to the two-dimensional code acquired by the identified scanning gun, and restoring real data corresponding to each piece of simulation key information; 104. and taking the specific end symbol of the two-dimensional code as an end mark, acquiring real data corresponding to a plurality of pieces of simulated key information before the two-dimensional code end symbol, and sending the real data to the application layer.
It can be understood that, based on the defects in the background art, in order to solve the above problems, the upper computer program preferably can automatically acquire the real data corresponding to the two-dimensional code without manual operation, so as to avoid the problems of complexity in manual operation and occurrence of manual operation.
The embodiment of the invention is specifically realized in such a way that a system keyboard hook is installed in an upper computer program to monitor all keyboard data, simulated key information corresponding to the two-dimensional code is identified from all keyboard key information, a specific end symbol of the two-dimensional code is used as an end mark, and the obtained two-dimensional code simulated key data is transmitted to an application layer code.
According to the embodiment of the invention, the system keyboard hook is arranged on the program background, so that all key information can be automatically acquired under the condition of no text input box, the two-dimension code simulation key information is identified from the key information, the corresponding real data is analyzed, manual operation is not needed in the whole process, and the problems caused by the manual operation or caused by the manual operation can be reduced.
In one possible embodiment, each key information monitored by the system keyboard hook is stored in a buffer queue.
It can be understood that a system keyboard hook is installed in the upper computer program, and the system keyboard hook can monitor and acquire each piece of key information and store each piece of key information acquired through monitoring in a cache queue. For example, for data in the two-dimensional code 123456789, 9 pieces of key information are monitored, and the 9 pieces of key information are stored in the cache queue, where the two-dimensional code data are directly scanned by the scanning gun, for manual key information, the system keyboard hook may also monitor, and similarly, for manual key information, the manual key information is also stored in the cache queue. And for all the key information, sequentially storing each piece of key information in a cache queue.
In a possible embodiment mode, all the key information comprises manual key information and simulated key information corresponding to the two-dimensional code acquired by the scanning gun; based on the key information, identifying each piece of simulation key information corresponding to the two-dimensional code acquired by the scanning gun from the key information, and the method comprises the following steps: acquiring a time difference between any two adjacent pieces of key information from the cache queue, and when the time difference between any two adjacent pieces of key information is smaller than a preset time threshold, judging that the any two adjacent pieces of key information are analog keys corresponding to the two-dimensional codes acquired by the scanning gun; and when the time difference between any two adjacent key information is greater than a preset time threshold value, judging that any two adjacent keys are artificial key information.
It can be understood that, for the key information cached in the cache queue in sequence, the time difference between any one pair of adjacent two key information in the cache queue is obtained, and if the time difference is smaller than the preset time threshold, the two adjacent key information is considered as the simulated key information corresponding to the two-dimensional code data obtained by the scanning gun; and if the time difference is greater than a preset time threshold value, the two adjacent key information are considered as manual key information.
And by utilizing the principle that the time difference between the analog keys corresponding to the two-dimensional code is generally small, setting the key interval to be less than 100ms is the analog key of the two-dimensional code, and otherwise, setting the key interval to be a manual key.
After each piece of key information is judged to be analog key information or manual key information, if the manual key information is judged to exist in the cache queue, the manual key insertion indicates that the original data is interfered and needs to be discarded, the key information in the cache queue is cleared, and the analog key information corresponding to the two-dimensional code needs to be processed in the middle value.

It can be understood that, each piece of identified simulated key information is analyzed, and specifically, according to the state of the CapsLock key and the state of the Shift key, real data corresponding to the simulated key information is restored. For example, if the acquired simulated key information is a Shift + a key, the restored real data is a; similarly, if the acquired simulated key information is a CapsLock + A key, the restored real data is A, and the original real data can be restored by analyzing the key information according to the captured key information or the combined key information.
In a possible embodiment mode, the specific end symbol of the two-dimensional code is a TAB key or an ENTER key; the method for acquiring the real data corresponding to the plurality of pieces of simulated key information before the two-dimensional code end symbol by taking the specific end symbol of the two-dimensional code as the end symbol and sending the real data to the application layer comprises the following steps: acquiring a plurality of pieces of simulation key information before the two-dimensional code end symbol, and analyzing each piece of simulation key information to obtain corresponding real data; and caching the real data corresponding to each piece of simulation key information in an array, and sending the real data corresponding to the simulation key information cached in the array to the application layer.
It can be understood that, for each piece of simulated key information, corresponding real data can be restored, data included in one two-dimensional code may correspond to a plurality of pieces of simulated key information, and then how many pieces of simulated key information correspond to one two-dimensional code, and a plurality of pieces of simulated key information before the two-dimensional code end symbol can be obtained according to a specific end symbol of the two-dimensional code as an end mark, that is, the simulated key information included in one two-dimensional code.
And acquiring a plurality of pieces of simulation key information before the end character, analyzing each piece of simulation key information to obtain corresponding real data, caching the real data corresponding to each piece of simulation key information in an array, and sending the real data corresponding to the simulation key information cached in the array to an application layer for subsequent processing of the application layer. In a possible embodiment, sending real data corresponding to the simulated key information cached in the array to the application layer includes: and carrying out data verification on the real data corresponding to each piece of simulated key information, and sending the real data passing the verification to the application layer.
It can be understood that, in the process of sending the restored real data of the simulated key information to the application layer, the real data is verified, for example, the real data corresponding to the two-dimensional code is usually of a fixed length, if the length of the analyzed real data is not of a fixed length, it indicates that the real data is incorrect, and the real data is discarded, or the real data corresponding to the two-dimensional code is provided with a check code, which can ensure the correctness of the data through the check code, and only the real data that passes the check is sent to the application layer.
