[0037] It reduces costs and solves the problem that when processing information interaction data, software developers need to encapsulate / parse business data and write a lot of code. It also solves the problem that after coding is completed, software testers are still required to perform unit testing, functional testing, performance testing, etc. on related modules, which takes up a lot of development and testing time and consumes high costs.

[0038] It improves security and solves the problem that software developers need to code according to protocol documents and software testers also need to design test cases according to protocol documents for testing. There are many links involved, and important protocol information may be leaked during the circulation process, causing security problems.

[0039] It enhances scalability and solves the current protocol encapsulation / parsing. When faced with new protocols or protocol changes, redesign is often required, which may require a lot of modifications from the bottom-level coding or will face a series of problems such as repeated development and testing.

[0040] The present invention represents the data elements of the protocol by fields, and the user can enter the information of each field of the protocol through the human-computer interaction interface.

The compiler is used to compile the protocol encapsulation / parsing code to form a dynamic library that can be used by upper-layer services. Other developers can directly use the dynamic library for secondary development without further adjustment or testing.

User login module access control data security and encryption module, visual protocol editing module access data security and encryption module.

[0050] It also includes a tree protocol data format module, a data security and encryption module to encrypt / decrypt the tree protocol data format module. In order to ensure data security, the encryption storage and user access authority control method of the tree protocol data format file is preferred.

[0051] Among them, the tree-shaped protocol data format module is used to store the protocol data and data element information entered by the user. The tree-shaped protocol data format module preferably adopts the Json / Xml file storage protocol structure. The present invention proposes to adopt the Json / Xml file storage protocol structure, perform hierarchical and layered management on the protocol structure, and provide the upper and lower level and same level element relationships of each node in the Json / Xml structure, which can clearly and accurately represent the parallel relationship, nested relationship, and associated relationship within the protocol.

[0056] Software engineers can use the business encapsulation / parsing library for secondary development, such as: for use by upper-level businesses, or to develop general data encapsulation and parsing software tools.

[0057] The implementation steps of a visual protocol analysis device according to an embodiment of the present invention are as follows:

[0058] (I) User login module

[0059] By obtaining the stored user name, password, key and other information for comparison and verification, the login access results and operation records are encrypted and stored.

[0060] (II) Visual protocol editing module

[0061] Users can edit (add / delete / modify) protocol data, edit (add / delete / modify) protocol fields, and change (move up / down) field structure and position. A field can be a data element or a block of data elements.

[0062] (1) The information of data elements includes: element name, element ID, internal number, classification, type, length (bits), identifier, and remarks;

[0063] (2) Supported data types include: character type (char), Boolean type (bool / BOOL), integer type (short / int / long / long long), floating point type (float / double), string type (char* / char[]), unsigned type (unsigned char / unsigned short / unsigned int / unsigned long), etc.;

[0064] (3) Ability to enter message data structure with bytes or bits as the minimum unit;

[0065] (4) A code capable of displaying the data elements of the message;

[0066] (5) Defines the internal data structure of DATA, GROUP, GROUP_FLAG, STRUCT, ARRAY, and ARRAY_NUM to distinguish data elements, as follows:

[0067] (a) DATA: represents data. The data types corresponding to the smallest unit include character type (char), Boolean type (bool / BOOL), integer type (short / int / long / long long), floating point type (float / double), string type (char* / char[]), unsigned type (unsigned char / unsigned short / unsigned int / unsigned long), etc.

[0068] (b) GROUP: represents a data block composed of multiple data elements with related relationships;

[0069] (c) GROUP_FLAG (Group Flag): Indicates the available flag of the group data block. During protocol encapsulation / parsing, this field can be used to determine whether the group data content is used / existed;

[0070] (d) STRUCT (structure): represents a structure composed of multiple data elements, corresponding to the struct structure;

[0071] (e) ARRAY: indicates that data (DATA) / structure (STRUCT) appears in the form of an array;

[0072] (f) ARRAY_NUM (array length): the length of the ARRAY structure (number of loops), and the corresponding internal message organization structure of the Json / Xml file is as follows Figure 2 shown.

[0073] (III) Protocol encapsulation / analysis code generation module

[0074] According to the Json / Xml file, the protocol is translated into code that can be recognized by the compiler. Through the information and classification of each data element defined by the visual protocol editing module, it is parsed / encapsulated according to data type processing and logical combination.

[0075] (IV) Business encapsulation / analysis library generation module and protocol encapsulation / analysis library module

[0076] The business encapsulation / parsing library is a target file. The compiler compiles according to the protocol encapsulation / parsing code to generate a directly usable function library, which contains data encapsulation and data parsing related services. Users can use the business encapsulation / parsing library to conduct secondary development and use conveniently and quickly.

[0077] (V) General data encoding and decoding library module

[0078] The general data encoding and decoding library mainly provides interface files to the protocol encapsulation / analysis code generation module, including the specific implementation of various data encoding, decoding logic, and functions in DATA (data); there is no need to repeatedly write complicated encoding / decoding logic inside the protocol encapsulation / analysis code generation module, and it can be done by simply introducing a dynamic library. After the business encapsulation / analysis library is generated, the general data encoding and decoding library can be used by the business encapsulation / analysis library to directly provide data encoding and decoding functions.

[0079] (VI) Data security and encryption module, user information and access record module, and tree protocol data format module

[0080] User information, user access records, etc. are encrypted / decrypted through encryption algorithms, and tree-shaped protocol data format (Json / Xml) data formed by visual protocol editing is encrypted / decrypted to ensure data security.

[0081] (VII) Secondary development software component modules and general data packaging and analysis software modules

[0082] Users can develop software components by using business encapsulation / parsing libraries and general data encoding and decoding libraries to complete corresponding businesses, and can also develop corresponding general data encapsulation and parsing software.
