In an embodiment, as shown in fig. 2, a two-dimensional code generating method is provided, which is described by taking the application of the method to the first terminal in fig. 1 as an example, and includes the following steps:
The first terminal can acquire different types of two-dimensional code contents according to different application scenes of the two-dimensional code. The first terminal divides the two-dimensional code content to be coded into a plurality of groups according to different actual purposes. For example, a two-dimensional code for opening an intelligent access control, a gate identification two-dimensional code for subway trips, and two-dimensional code for offline mobile phone payment. The first terminal obtains corresponding character information according to different contents of the two-dimensional code, wherein the character information comprises existing two-dimensional code characters and newly added characters. One two-dimensional code can describe various types of information, the existing two-dimensional code characters are obtained according to historical information or existing two-dimensional code functions, and the newly added characters can be newly added character information obtained according to newly added content information or purposes of the two-dimensional code.
And 204, dividing the existing two-dimension code characters into compatible partitions, and dividing the newly added characters into custom partitions.
The first terminal can be divided into different partitions according to different types of the two-dimensional codes according to different contents of the obtained two-dimensional codes, specifically, existing two-dimensional code characters are divided into compatible partitions, newly-added characters are divided into custom partitions, the partitions can comprise two-dimensional code content sets of the same type, the compatible partitions can comprise compatible partitions of a plurality of different types, and the custom partitions can be two-dimensional code content custom-added new characters and custom descriptions produced by workers according to needs. Furthermore, the first terminal can split the custom partition into a plurality of different segments according to different purposes of the newly added characters in the custom partition, the content of each segment can be compatible with information such as text characters and links, and the encryption mode supports dynamic expansion.
And 208, coding a plurality of segments corresponding to the user-defined partition by using a preset protocol to obtain a user-defined segment description.
And step 210, splicing the existing two-dimension code characters of the compatible subareas with the self-defined section description to generate compatible two-dimension code characters.
The first terminal encodes a plurality of segments corresponding to the self-defined partition according to the different divided regions by using a preset protocol, for example, the first terminal may encode the self-defined segment in the self-defined partition by using a TLV protocol to obtain a self-defined segment description. And the first terminal splices the self-defined section description with the existing two-dimensional code characters in the compatible subarea, generates compatible two-dimensional code characters and sends the compatible two-dimensional code characters to the second terminal.
In this embodiment, the existing two-dimensional code characters and the newly added characters are obtained, the existing two-dimensional code characters are classified into the compatible partition, and the newly added characters are classified into the custom partition. And splitting the user-defined partition into a plurality of segments according to the application of the newly added character, and encoding the plurality of segments corresponding to the user-defined partition by using a preset protocol to obtain the description of the user-defined segment. And splicing the existing two-dimensional code characters of the compatible partitions with the self-defined segment description to generate compatible two-dimensional code characters. By adopting a partition segmentation mode, the two-dimension code characters are divided into compatible areas and self-defined areas, the newly-added characters of the two-dimension code of the self-defined partition are coded and spliced with the compatible partitions, and compared with a traditional two-dimension code generation mode, the two-dimension code characters with different contents can be compatible by different partitions, so that the compatibility of the two-dimension code characters is improved.
In an embodiment, as shown in fig. 3, the step of encoding a plurality of segments corresponding to the custom partition by using a preset protocol to obtain a description of the custom segment includes:
And step 304, enumerating the character string type corresponding to the custom segment according to the preset character length.
And step 306, encrypting the custom segment to obtain the character string content of the custom segment.
And 308, calculating and coding the character string content of the custom section to obtain the character length corresponding to the character string content.
And 310, combining the character string type, the character string content and the character length corresponding to the character string content to obtain the self-defined segment description.
The first terminal encodes a plurality of segments corresponding to the user-defined partition by using a preset protocol according to the different divided regions, so that the description of the user-defined segment can be obtained. Specifically, the first terminal marks the segment corresponding to the custom partition as a custom segment, and enumerates the character string type corresponding to the custom segment according to the preset defined character length. The preset character length may be 2 characters. Further, the first terminal may encrypt the custom segment by using different encryption technologies to obtain the string content of the custom segment. The first terminal calculates the obtained character string content, calculates the character length corresponding to the character string content, and then performs code conversion on the character string content according to different coding modes to obtain the character length corresponding to the converted character string content. And the first terminal combines to obtain the self-defined segment description according to the character string type, the character string content and the character length corresponding to the character string content by utilizing the TLV protocol.
The new characters to be encoded are taken as an offline character string for example. The first terminal marks the segments corresponding to the custom partition as custom segments, enumerates the type of the character string according to the preset defined character length, and the preset character length can be 2 characters. The pre-preparing of the character string type of the custom segment by the first terminal may include: offline character strings, offline algorithmic descriptions, online character strings, and the like. The first terminal enumerates the character string types corresponding to the custom segments, for example: 01 corresponds to an offline character string, sf corresponds to an offline algorithm description, 02 corresponds to an online character string, and the like. Further, the first terminal encrypts the content to be encrypted by using a 3des encryption technology, and the content of the offline character string is obtained as 10997. The first terminal calculates the character string content 10997 of the custom section to obtain the character length 04 corresponding to the corresponding character string content. And then 16-system coding is carried out on the character string content 10997 to obtain the converted character string content of 2AF 5. The first terminal utilizes TLV protocol according to the character string type of 01, the character string content of 2AF5 and the character length corresponding to the character string content of 04 to combine to obtain the self-defined segment description of 01042 AF 5. Therefore, the two-dimensional code can be compatible with the contents of a plurality of different partitions without mutual influence, the problem of inconsistent codes of various two-dimensional code reading heads is solved by partitioning the compatible regions and the user-defined regions, and the compatibility of the two-dimensional code is effectively improved.
In one embodiment, the step of encoding a plurality of segments corresponding to the custom partition by using a preset protocol to obtain a description of the custom segment further includes:
matching the character length corresponding to the self-defined section character string content with the preset self-defined section parameters, and carrying out validity verification.
And in the process of coding, the first terminal can carry out validity verification by matching the character length corresponding to the self-defined section character string content with the preset self-defined section parameter. For example, the length of the character corresponding to the custom segment character string content in the custom segment parameter is preset to be 08, but when validity verification is performed, the length of the character corresponding to the custom segment character string content is identified to be 088, that is, an incorrect TLV code is generated. Therefore, in the encoding process, through validity check, whether wrong TLV encoding occurs in the user-defined partition can be effectively checked, and the two-dimensional code character string which cannot be identified is prevented from occurring.
In one embodiment, the step of encoding a plurality of segments corresponding to the custom partition by using a preset protocol to obtain a description of the custom segment further includes:
and matching the character string type corresponding to the custom section with the preset custom section parameters, and carrying out validity verification.
In the process of coding, the first terminal can also perform validity verification by matching the character string type corresponding to the custom segment with the preset custom segment parameters. For example, the type of the string corresponding to the custom segment in the preset custom segment parameter is 01 offline string, but when validity verification is performed, it is recognized that the type of the string corresponding to the custom segment is 02 online string, and the TLV code is also wrong. Therefore, in the encoding process, through validity check, whether wrong TLV encoding occurs in the user-defined partition can be effectively checked, and the two-dimensional code character string which cannot be identified is prevented from occurring.
In an embodiment, as shown in fig. 4, a two-dimensional code identification method is provided, which is described by taking an example that the method is applied to the second terminal in fig. 1, and includes the following steps:
The two-dimensional code reading head can be installed and embedded on various terminal devices to be used as a two-dimensional code identification component. For example, the two-dimensional code reading head is packaged and assembled with an outer shell to form a common scanning gun in a supermarket of a shopping mall, the two-dimensional code reading head is installed on a self-service vending machine, and self-service payment can be realized by placing a payment treasure or a WeChat payment code into a two-dimensional code payment window (namely a payment code sensing area) of the machine. The two-dimensional code reading head can read the two-dimensional code characters and the pre-made self-defined segment description by identifying the compatible two-dimensional code characters received by the second terminal in the embodiment, wherein the self-defined segment description is a character string generated after the pre-set protocol is used for coding. The reading code format can be various, for example, (iso-8859-01).
And step 404, identifying partition separators in the two-dimensional code characters, and obtaining a plurality of corresponding partitions according to the partition separators.
At step 406, segment separators are read from each partition, and each partition is parsed into a plurality of segments.
And 408, identifying the character string type corresponding to the segment, and matching the character string type with the self-defined segment description.
And step 410, if the matching is successful, determining the partition corresponding to the segment as a user-defined partition, and analyzing the newly added characters corresponding to the user-defined partition.
And step 414, generating scanning information by using the analyzed new characters and the existing two-dimensional code characters.
The two-dimensional code reading head reads the two-dimensional code content character by identifying the compatible two-dimensional code character received by the second terminal in the embodiment, the two-dimensional code reading head reads the two-dimensional code content according to the partition analysis by default, when the partition division character is encountered, the partition reading is finished, the next partition reading is carried out, and therefore a plurality of corresponding partitions are obtained according to the read partition division character. Wherein the plurality of partitions may include compatible areas and custom areas. Further, when the two-dimensional code reading head reads in each partition, when encountering a partition separator, the two-dimensional code reading head performs the partition reading, thereby resolving each partition into a plurality of partitions. And when the segment is read, identifying the character string type corresponding to the segment, and matching the character string type with the self-defined segment description. And judging whether the character string type is matched with a previously preset character string type, for example, whether the two-bit length character at the beginning of the segment is matched with 01, and when the matching is successful, indicating that the segment is a self-defined segment and carrying out self-defined analysis. Specifically, the two-dimensional code reading head reads the segment and performs decryption operation, for example, using 3des to perform parsing to obtain the original content of the custom segment. After the segment is read, the next segment is read downwards to determine whether the segment is a custom segment. And if the new characters do not exist, starting to read the next partition, if the next partition does not exist, finishing the two-dimensional code analysis, and generating scanning information by using the newly added analyzed characters and the existing two-dimensional code characters. When the matching fails, the segment is a common segment, and common segment analysis is carried out. Specifically, the two-dimensional code reading head reads the segment to obtain the existing two-dimensional code characters. After the reading of the segment is finished, reading down whether a segment separator exists, and if so, continuing to read the next segment; and if the new characters do not exist, starting to read the next partition, if the next partition does not exist, finishing the two-dimensional code analysis, and generating scanning information by using the newly added analyzed characters and the existing two-dimensional code characters.
In this embodiment, the two-dimensional code characters and the custom segment description are read to identify the partition separators in the two-dimensional code characters, and a plurality of corresponding partitions are obtained according to the partition separators. Reading a segmentation separator in each partition, analyzing each partition into a plurality of segments, identifying a character string type corresponding to each segment, and matching the character string type with the self-defined segment description. And if the matching is successful, determining the partition corresponding to the segment as a user-defined partition, and analyzing the newly added characters corresponding to the user-defined partition. And if the matching fails, determining the partition corresponding to the segment as a compatible partition, and reading the existing two-dimensional code character corresponding to the compatible partition. And generating scanning information by using the analyzed new characters and the existing two-dimensional code characters. By matching the character string type with the custom section description, the partition corresponding to the section can be determined to be the custom partition, the newly added characters corresponding to the custom partition are analyzed, and compared with the traditional two-dimensional code identification mode, the scanning information is generated by the newly added characters after the analysis and the existing two-dimensional code characters, so that the information of two-dimensional codes of different types can be identified, and the compatibility of the two-dimensional codes is improved.
In an embodiment, as shown in fig. 5, the step of parsing the new characters corresponding to the custom partition includes:
And step 506, decoding the character string content according to the character string type to obtain the scanning information corresponding to the custom segment description.
When the two-dimensional code reading head reads the segmentation separators in each partition, each partition is analyzed into a plurality of segments, the character string type corresponding to each segment is identified, and the character string type is matched with the self-defined segment description. And when the matching is successful, performing custom analysis. Specifically, the two-dimensional code reading head reads the self-defined segment description according to a preset character length to obtain a corresponding character string type, for example, the preset character length may be 2 characters. Further, the two-dimensional code reading head reads the character length corresponding to the character string content, the character length is converted to obtain the corresponding character string content, the two-dimensional code reading head can decode the character string content by using different decryption methods, for example, when the character string type is read as sf offline algorithm description, the character string content is decrypted according to the offline algorithm description, and the scanning information corresponding to the custom segment description is obtained.
Illustrated with the custom segment description 01042 AF 5. The two-dimensional code reading head starts to read the characters with the length of 2 according to the preset character length to obtain the character string type corresponding to the character string 01 as an offline character string. And reading 2 characters with the length of 04 to obtain the character length 04 corresponding to the character string content, reading 4 characters with the length of 4, wherein the 2AF5 corresponding to the 4 characters is the character string content of the two-dimensional code, and converting the character string content 2AF5 coded in the 16 system into the 10 system to obtain the character string content 10997. The two-dimensional code reading head can decode the character string content 10997 by using a 3des technology to obtain the scanning information corresponding to the custom segment description. Therefore, the decoding program of the two-dimensional code reading head program from the designated identifier to the designated identifier can be compatible, even if the same two-dimensional code is used, different two-dimensional code information can be identified according to different requirements, the reading head device does not need to be changed too much, and the good compatibility of the two-dimensional code is realized.
