Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Existing product type codes typically classify products according to their structural features, and name the products by a combination of numbers, letters, and special symbols. A product corresponds to a unique code sequence, each character or character segment in the code having a particular meaning. However, in the prior art, standards for product type code rules are established empirically, and the obtained generated codes are not checked by a strict check process, and the readability of the product type codes is generally poor because the product type codes are established empirically.
Therefore, in the prior art, the making and analyzing processes of the product model codes also lack related technical schemes, and the readability of the obtained product model codes is further improved.
Based on the above, the method, the device and the electronic equipment for generating the product code provided by the embodiment of the invention can process the key and the value of the key value pair in the pre-constructed code database, realize the analysis generation of the code in a data filling mode, realize the normative acquisition of the product code and improve the readability of the product code.
For the sake of understanding the present embodiment, first, a method for generating a product code disclosed in the present embodiment will be described in detail.
Referring to fig. 1, a flowchart of a method for generating a product code is shown, where the method specifically includes the steps of:
step S101, a plurality of key value pairs corresponding to a plurality of product attributes of a target product are obtained from a pre-established coding database, and the plurality of product attributes are in one-to-one correspondence with the plurality of key value pairs.
In the construction of the encoding database, various categories of product attributes are included, which may be considered as types, as well as categories, such as: size, color, weight, model, etc. of the product. The data in each class contains key-value pairs corresponding to the classes, the keys in the key-value pairs can be considered as subclasses of the class, the values can be considered as corresponding specific parameters, the content of the keys is generally unchanged, and the content of the values is variable.
For example, a pre-established encoding database is shown below:
size1 (color class): { color1: 'black', color2: 'white', … …, colorN: '…' }
Size2 (character class): {: 'open', b: 'Mimosa', … …, Z: '…' }
…
Sizen (age class): { age1: '0-10', age2: '10-20', … …, ageN: '…' }
The standardized database of this composition is: DATA (name) = { Size1, size2, …, sizeN }.
The key value pair of the class measures the attribute data of the product under the class, and the result is stored in a pre-established coding database by formatting the data of various classes corresponding to the product attribute. In the process of generating the product code, only the code database is required to be searched for the key value pair corresponding to the required class, and the key and the value corresponding to the obtained key value pair are unique, so that the key value pair data can be used as a data source for generating the subsequent product code.
Step S102, generating a first code according to a plurality of values included in a plurality of key-value pairs, wherein each key-value pair comprises a key and a value corresponding to the key.
Since the obtained keys and values in the plurality of key-value pairs are unique, the keys and the values have a one-to-one correspondence, only the values in the key-value pairs can be used to replace the keys, and the first code can be generated by combining the values in the different key-value pairs.
The first code generated at this time may be affected by a value, and may have a non-uniform length. For example, a key value pair of a certain product weight is obtained, and if one of the key value pairs is 1, the key value pair is 1 digit; and the other value is 10 and is 2 digits, so that the length difference is 1 when the corresponding first codes are acquired; similarly, when measuring the class of product models, different letter combinations may be involved, resulting in a larger difference in corresponding first code lengths. The resulting first code length may not even be logically uniform, but the generated first code is unique.
Step S103, filling the first code by using a preset mark to generate a second code.
Not only is the situation that the lengths of the first coding median value are different filled, but also incomplete data in a pre-established coding database is considered to be filled. Since the types of products are diverse and are affected by the integrity of the data acquisition, there are often a number of drawbacks in the first encoding:
1. there are cases in which the value of the key is omitted in some classes;
2. the length of the bond is different;
3. the keys are unique in this class, but duplicates occur in a different class; it is understood that the bonds are the same and the values are different;
4. the length of the code is different.
In the process of filling the first code by using the preset mark, the preset mark used needs to be in a unified format, and the length of the second code generated after filling of different types needs to be the same, and is generally the same as the length of the finally generated product code.
Filling the first code after the length is determined, arranging and combining the first code and a preset mark in a full arrangement mode, and taking the arrangement and combination result as a second code; or only arranging and combining the corresponding values of part of product attributes in the first code with preset marks according to the requirements; the sequence of the product attributes can be defined in the process of arranging and combining, and the sequence is consistent with the sequence of the corresponding attributes in the finally obtained product codes.
Step S104, analyzing the second code according to the plurality of values to generate a product code.
After the second code is obtained, the second code is analyzed by using a plurality of values in the key value pair, a fixed direction can be selected for sequential traversal in the specific implementation process, for example, the second code is sequentially analyzed from left to right, values with different lengths are sequentially selected for respective analysis, and finally the product code is generated.
In the method for generating the product code, which is disclosed by the embodiment of the invention, a plurality of key value pairs corresponding to a plurality of product attributes of a target product are firstly obtained from a pre-established code database, and the plurality of product attributes and the plurality of key value pairs are in one-to-one correspondence; generating a first code according to a plurality of values included in a plurality of key-value pairs, each key-value pair including a key and a value corresponding to the key; filling the first code by using a preset mark to generate a second code; and finally, analyzing the second code according to the multiple values to generate a product code. The keys and the values of key value pairs in the pre-constructed coding database are exchanged, and the analysis generation of the codes is realized in a data filling mode, so that the normative acquisition of the product codes is realized, and the readability of the product codes can be improved.
In some embodiments, the step S102 of generating the first code according to the plurality of values included in the plurality of key-value pairs, as shown in fig. 2, includes the following steps:
step S201, obtaining a plurality of values included in the plurality of key-value pairs.
Because the plurality of product attributes are in one-to-one correspondence with the plurality of key value pairs, and the key value pairs corresponding to the product attributes are unique, the related keys and the related values have one-to-one correspondence, a plurality of values contained in the plurality of key value pairs can be obtained through traversing and reading the key value pairs for subsequent use.
Step S202, combining the values according to a preset sequence to generate a first code.
The combination process may be performed in an inherent order, or sequentially in front of the data, or sequentially in back of the data, but the order needs to be consistent. The values of the corresponding key value pairs in different types of product attributes can be divided by specific symbols to distinguish different types.
In some embodiments, the step S103 of filling the first code with a preset flag to generate the second code, as shown in fig. 3, includes:
step S301, obtaining a preset length of a second code; wherein the predetermined length of the second code is greater than the length of the first code.
The preset length of the second code is related to the values of the key-value pairs of all classes contained in the first code, and cannot be smaller than the sum of the lengths of the values of all classes in the first code. For example, the first code includes four classes, and the maximum length of the value in each class is 1, 2, 3, and 4, so the preset length of the second code cannot be lower than 1+2+3+4=10.
Step S302, traversing the values in the first encoding, and obtaining the sequence of the values in the first encoding.
In this step, the value in the first code is actually a key in the pre-established code database, so that during the traversal, a search can be performed according to the type of key in the code database, and the resulting order remains unchanged during the subsequent interpolation. Maintaining the order of values relative to the full permutation may reduce the amount of subsequent computations.
Step S303, filling the first code by using a preset mark according to the sequence of the values in the first code, and generating a temporary code.
The above-described filling process still adopts a full permutation mode, but since the order of values in the first code has already been defined, the amount of computation in the temporary code generation process is greatly reduced. As shown in fig. 4, the method comprises the following steps:
step S41, the sequence of the values in the first code is kept unchanged, and the first code is randomly filled by using a preset mark.
In a specific implementation process, the sequence of the values in the first code may be stored in a temporary array, and the corresponding sequence of the values is obtained by reading the array.
Step S42, the first code after filling is used as a temporary code.
Since the preset marks are in a unified form, the first code can be randomly filled with the preset marks to obtain the temporary code under the condition that the sequence of the values in the first code is kept unchanged.
Step S304, stopping filling when the length of the temporary code is equal to the preset length of the second code, and taking the temporary code as the second code.
It can be seen that, although the above-mentioned filling process still adopts a full permutation mode, since the sequence of values in the first encoding is defined, the operand in the second encoding process is reduced, which is beneficial to improving efficiency.
The preset marks in the above embodiment are numbers and/or letters different from the values in the first code. The predetermined flag cannot be the same as the value contained in the first code, otherwise it will affect the subsequent parsing process and generate errors.
In some embodiments, the step S104 of parsing the second code according to the plurality of values to generate the product code, as shown in fig. 5, includes:
step S501, obtaining a plurality of first values through second coding, wherein the first values comprise preset marks;
the process of obtaining the plurality of first values may be obtained by traversing the second code, and may specifically be performed by parsing the second code along a left-to-right direction, or may be performed along a right-to-left direction. The first value is obtained as a description of the first value and a preset mark, the description being intended for subsequent use.
Step S502, deleting preset marks in the first values to obtain a plurality of second values; wherein the plurality of second values are in one-to-one correspondence with the plurality of first values;
since the first value includes not only the preset mark but also the descriptive contents, the result obtained after deleting the preset mark is noted as the second value. Since there are a plurality of first values, the obtained second values are also a plurality of and correspond to the first values one by one.
Step S503, matching the plurality of second values with the plurality of values in the first code, and if the plurality of second values are successfully matched with the plurality of values in the first code, taking the second code as a product code;
the matching process can be implemented by traversing the values in the first code, specifically, the values in the first code can be traversed by the second values, the values in the first code can be searched by the second values, and if the values in the second code and the values in the first code can be searched, the second code is taken as the code of the product.
In some embodiments, the method for generating a product code further includes:
judging whether the product code is consistent with the key value pair in the first code; if yes, keeping the product code unchanged; if not, regenerating the product code.
The step is used as a verification step, the generated product code can be verified, the generation process of the product code can also be verified, and if the product code is found to be inconsistent with the corresponding first code, the product code needs to be generated again.
According to the method for generating the product code, which is disclosed by the embodiment, keys and values of key value pairs in a pre-constructed code database are exchanged, and the analysis generation of the code is realized in a data filling mode, so that the normative acquisition of the product code is realized, and the readability of the product code can be improved.
