Description

A naming matching method based on json format data

technical field

The invention relates to application fields such as communication network information, network planning and communication protocols, and in particular to a naming matching method based on JSON format data.

Background technique

With the rapid development of informatization and industrialization, the level of informatization of enterprises has been continuously improved, and the unsmooth information exchange has also become a major bottleneck in informatization construction. As an important part of various computer network applications, data exchange has gradually become the main means to solve the phenomenon of "information islands", and it is also a difficult problem that must be faced in the current information construction. With the rapid development of Web technology, applications based on B/S architecture are becoming more and more abundant, and there are more and more methods of data exchange and data analysis between client and server. The data exchange format is used to improve the efficiency of data transmission, so that the application program can be executed efficiently and the user experience is better. In traditional engineering applications, the traditional way of data exchange and data analysis between client and server has low exchange and analysis efficiency, which seriously affects the system effect and user experience based on the B/S architecture system. People are trying to find A data exchange format with low data transmission overhead to improve the efficiency of data transmission, so that the application program can be executed efficiently and the user experience is better.

JSON (JavaScript Object Notation) is a lightweight data exchange format based on a subset of ECMAScript. json adopts a text format that is completely independent of language, but also uses habits similar to the C language family including C, C++, C#, Java, JavaScript, Perl, Python, etc. These features make JSON an ideal data exchange language. It is easy for people to read and write, and it is also easy for machines to parse and generate, which greatly improves the network transmission rate. The data format of json format data is relatively simple, easy to read and write, the format is compressed, occupies relatively small bandwidth, and supports multiple languages at the same time, which is convenient for server-side analysis. For most web applications, there is no need for complex XML to transfer data at all, and the json data exchange format provides better simplicity and flexibility.

In traditional engineering applications, all kinds of basic data are recorded in the form of handwriting, and sometimes in the form of digital data. Extensible Markup Language XML is an earlier format for data exchange. It is a simple data storage language, easy to master and use, and has the advantages of readability and strong descriptiveness. However, XML takes up more space than binary data. Space, displayed on the client needs to be parsed through the DOM tree. For structured data (or relational data), the anonymity protection of data publishing is the core key technology and basic means to realize its privacy protection, and it is still in the stage of continuous development and improvement.

Therefore, there are many defects in the current data parsing and matching technology, which need us to improve.

Contents of the invention

In order to overcome the shortcomings of existing naming matching methods, such as inefficient transmission, insufficient data protection, and insufficient user experience, the present invention provides a naming method based on json format data that can effectively protect data, improve data transmission efficiency, and improve user experience. matching method.

The technical solution adopted by the present invention to solve its technical problems is:

A naming matching method based on json format data, the naming matching method comprises the following steps:

1) Parameter initialization: set a set of n-layer nested json format data in Indicates the key value of data in json format, Indicates the data key value in json format The corresponding value, n indicates the number of nested layers of json format data, m indicates the number of groups of json format data corresponding to the nth layer, k, p, q, l, λ are used to identify the key and value for distinguishing json format data and {k,p,q,l,λ∈N+|0<k<p<q<l<λ};

2) Set the data identification to be matched as Wherein, name is a string formed by concatenating the key value of the data layer from outside to inside, where {l ₁ , l _k , l∈N+|0<l ₁ <l _k <l}, {n ₁ ,n _k , n∈N+|0<n ₁ ＜n _k ＜n}，{m ₁ ,m _k ,m∈N+|0＜m ₁ ＜m _k ＜m};

3) Split the data identifier to be matched, the process is as follows:

3.1) Use uppercase letters as the segmentation identifier, and divide the data identifier name to be matched into a w-dimensional array string[w], where w represents the array index;

3.2) According to the size of l as the sorting condition, from small to large, reorder string[w] to obtain a new w-dimensional array str[w], where w represents the array index;

4) Match data according to name, the process is as follows:

4.1) Set w=0, n=n ₁ , m=m ₁ , l=l ₁ , take str[0] as the starting point of the matching key value, that is, the key value of matching json format data str

4.2) Key value Match the json format data str, the obtained data value is

4.3) Judgment data value Whether it is data in json format;

4.4) If the data value For data in json format, go to step 4.5), otherwise go to step 4.6);

4.5) get w=w+1, take str[w+1] as the new matching key value, For the new json format data, go to step 4.2);

4.6) Determine whether the index of str[k] is equal to the dimension n of the array str[n], and if the condition is satisfied, the new The value obtained for the match.

Further, the naming method of the json format data str in step 1): the first letter of the key value of the n nested json format data is an uppercase letter.

The technical concept of the present invention is as follows: firstly, the data source is established on the basis of the n-layer nested json format data whose initial letter of the key value is uppercase; The values are concatenated in sequence; secondly, the search key value is split with uppercase letters as separators to form a key value array str[n], and the end condition is whether the searched value is json format data, and the number of searches is k; Finally, judge whether k is equal to n, and if it is equal, the data to be matched will be searched.

The beneficial effects of the present invention are: effectively protecting data, improving data transmission efficiency, and improving user experience.
