[0002] Communication analysis is an essential part of the railway signaling industry testing process. Due to various requirements such as industry specifications and security specifications, the definition of communication protocols between various types of equipment is highly complex, and there are large differences between different protocols. Currently, most of the testing process still uses manual packet capture inspection, and some communications use automated tools for analysis, but the analysis tools only support the analysis process of a specific type of message, and the tool's reusability is poor. Summary of the invention

[0003] The purpose of the present invention is to provide a universal communication message parsing method, device, electronic device and computer-readable storage medium to achieve decoupling of the parsing algorithm and the communication protocol, improve the reusability and flexibility of the parsing tool, avoid the situation of one protocol and one tool, reduce the work difficulty of testers, and improve work efficiency and quality.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0005] A communication message parsing method is used to parse data corresponding to all message types from a message to be parsed, comprising the following steps:

[0006] Obtain the message to be parsed and the corresponding configuration file, wherein the configuration file defines the parsing structure information of all message types, and the parsing structure contains information of several key values;

[0007] For each message type, the following processing is performed: obtaining the parsing structure of the message type, performing structural parsing according to the structural attributes defined in the parsing structure, and sequentially parsing the key values ​​contained in the parsing structure according to the defined key value attributes, and recording the parsing result of each key value in the parsing data record dictionary;

[0008] After parsing of all message types is completed, the parsed data record dictionary is output.

[0011] If the custom prefix attribute is empty or "-", the custom prefix of the current prefix is ​​set to empty, and the current prefix is ​​updated to the first position in the prefix list;

[0012] If the custom prefix attribute is not empty, obtain the prefix at the first position from the prefix list, combine it with the variable in the custom prefix attribute to form a variable name, and look up the value corresponding to the variable name in the current parsed data record dictionary, place the value as the custom prefix in front of the current prefix, and update the current prefix to the first position in the prefix list.

[0013] Optionally, the structural attributes of the parsing structure definition further include: a self-loop attribute, a self-loop merging attribute, and a loop count definition byte attribute;

[0014] The performing structural analysis according to the structural attributes defined in the analytical structure also includes:

[0015] If the self-loop attribute is "Y" and the self-loop merge attribute is not "Y", the first prefix in the prefix list is updated according to the number of self-loop cycles;

[0016] Determine whether the byte attribute for defining the number of loops is defined; if the byte attribute for defining the number of loops is not defined, parse each key value in the parsing structure in turn; if the byte attribute for defining the number of loops is defined, determine the number of loops according to the number of bytes defined by the attribute, and perform a cyclic parsing on the parsing structure according to the number of loops, each cyclic parsing creates a new group of substructures according to the current number of loops, and parses each key value record in the substructure in turn according to the parsing structure until the number of loops is completed.

[0017] Optionally, the structural attributes of the analytical structure definition further include: a self-loop condition parameter attribute, a self-loop condition determination method attribute, and a self-loop condition expected value attribute;

[0018] The performing structural analysis according to the structural attributes defined in the analytical structure also includes:

[0019] After the parsing is completed, determine whether the self-loop condition parameter attribute is empty or "-";

[0025] Determine whether the parsing condition parameter attribute of the current key value is empty or "-"; if the parsing condition parameter attribute is empty or "-", continue with the subsequent parsing; if the parsing condition parameter attribute is not empty or "-", then according to the variable in the parsing condition parameter attribute, in combination with the prefix list, look up the value of the variable in the parsing data record dictionary, and make a judgment according to the judgment method defined by the parsing condition judgment method attribute and the expected value defined by the parsing condition expected value attribute. If the judgment result is that the parsing condition is met, continue with the subsequent parsing; if the judgment result is that the parsing condition is not met, skip the current key value and perform the parsing of the next key value;

[0026] Determine whether the current key value needs to be parsed in a loop; if not, parse the message to be parsed according to the key value length, record the parsing result in the parsing data record dictionary, and then continue to parse the next key value; if cyclic parsing is required, determine the number of loops, and cyclically parse the current key value according to the number of loops. In each parsing, parse the message to be parsed according to the key value length, record the parsing result in the parsing data record dictionary, and continue to parse the next key value after the cyclic parsing is completed.

[0027] Optionally, determining the key value length of the current key value according to the parsed length attribute includes:

[0028] Determine whether the variable defined by the parsing length attribute is of int type. If it is of int type, determine the value of the variable defined by the parsing length attribute as the key value length of the current key value; if it is not of int type, then according to the variable defined by the parsing length attribute, combined with the prefix list, search for the value of the variable in the parsing data record dictionary, and use the value of the variable as the key value length of the current key value.

[0029] Optionally, the key value attributes of the key value definition include: a loop count attribute, a loop attribute based on a variable value, a special loop algorithm attribute, and a loop to end attribute;

[0033] Optionally, determining the number of cycles includes:

[0034] If the loop count attribute is not empty or "-", the value of the variable defined by the loop count attribute is determined as the loop count;

[0035] If the loop attribute based on variable value is not empty or "-", then according to the variable defined by the loop attribute based on variable value, in combination with the prefix list, the value of the variable is searched in the parsed data record dictionary, and the value of the variable is used as the number of loops;

[0036] If the special loop algorithm attribute is not empty or "-", data calculation is performed according to the logic processing function defined by the special loop algorithm attribute, and the calculation result is used as the number of loops;

[0037] If the loop to end attribute is "Y", the number of loops is set to -1.

[0038] Optionally, the performing cyclic parsing on the current key value according to the number of cycles includes:

[0039] If the number of loops is greater than 0, the current key value is looped according to the number of loops;

[0040] If the number of loops is -1, the current key value will be processed in a loop until all the information in the current parsing structure is parsed;

[0041] If the number of loops is 0, skip the current key value and execute the parsing of the next key value.

[0042] Optionally, the key-value attributes of the key-value definition include: substructure attributes;

[0075] The scheme proposed by the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer according to the following description. It should be noted that the accompanying drawings are in a very simplified form and are not in precise proportions, which are only used to conveniently and clearly assist in explaining the purpose of the embodiments of the present invention.

[0076] The existing technology has the following problems: 1. The inspection process of manual testing is inefficient, and it is easy to make mistakes in the inspection process; 2. The existing tool parsing process can only target a specific type of message, and has poor reusability; 3. If testers are expected to be able to implement the automated parsing process of new types of communication protocols, certain programming skills are required of the testers.

[0077] In view of the above problems, an embodiment of the present invention provides a communication message parsing method for parsing data corresponding to all message types from the message to be parsed. The execution subject of the method described in this embodiment can be an automated parsing tool, such as Figure 1 As shown, the method comprises the following steps:

[0078] Step S101: obtaining a message to be parsed and a corresponding configuration file, wherein the configuration file defines information of parsing structures of all message types, and the parsing structure includes information of several key values.

[0079] The parsing structure of each message type defines several structural attributes, including but not limited to: custom prefix attribute (Name_PRE_Mark), loop number definition byte attribute (NumberByte), self-loop attribute (Sub_Self_Repeat), self-loop merge attribute (Repeat_Combine), self-loop condition parameter attribute (Slef_Repeat_cond_Key), self-loop condition determination method attribute (Self_Repeat_Cond_Method), and self-loop condition expected value attribute (Self_repeat_Cond_Value).

[0080] Each key value of each parsing structure defines several key value attributes, which include but are not limited to: virtual calculation attribute (Virtual_Math), parsing length attribute (Msg Length), parsing condition parameter attribute (Cond_Key), parsing condition determination method attribute (Cond_Method), parsing condition expected value attribute (Cond_Value), loop count attribute (Param_Repeat_Time), loop based on variable value attribute (Repeat_Base_Var), loop to end attribute (Repeat_Till_End), special loop algorithm attribute (Repeat_Special), and substructure attribute (Sub_Struct).

[0081] It is understandable that a communication message of a communication protocol corresponds to a configuration file, in which different parsing structures are set according to the message characteristics of the protocol, and corresponding structural attributes and key-value attributes are defined. When a message to be parsed is obtained, the corresponding configuration file can be determined based on its communication protocol. Therefore, this embodiment can parse communication messages of different protocols by configuring different configuration files.

[0082] Step S102: For each message type, the following processing is performed: obtaining the parsing structure of the message type, performing structural parsing according to the structural attributes defined in the parsing structure, and parsing the key values ​​contained in the parsing structure in turn according to the defined key value attributes, and recording the parsing results of each key value in the parsing data record dictionary.

[0083] This embodiment uses a recursive method to parse the message to be parsed based on the configuration file. After the parsing tool reads the configuration file, it can obtain the structural information of all message types, and then parse each message type in turn. The overall parsing process is that the parsing tool disassembles, parses and updates the records from the message to be parsed into the parsing data record dictionary according to the structure of each message type.

[0084] For the message type to be currently parsed, the parsing tool obtains the parsing structure of the message type from the configuration file, and reads each structural attribute defined in the parsing structure.

[0085] First, set the custom prefix. Figure 2 As shown, it is determined whether the custom prefix attribute (Name_Pre_Mark) is empty or "-". If the custom prefix attribute is empty or "-", it means that the variable name of the parsing structure does not need to add a custom prefix, then the custom prefix of the current prefix is ​​set to empty, and the current prefix is ​​updated to the first position of the prefix list, so that the variable can be searched in sequence according to the hierarchy when the variable is queried subsequently.

[0086] If the custom prefix attribute is not empty or "-", it means that the variable name of the parsing structure needs to add a custom prefix, then the existing prefixes are obtained from the prefix list in turn, combined with the variables in the custom prefix attribute to form a variable name, and the value corresponding to the variable name is searched in the current parsing data record dictionary. If it is not found, the query continues according to the prefix list; if it is found, the value is placed in front of the current prefix as a custom prefix, and the current prefix is ​​updated to the first position in the prefix list. If the qualified variable cannot be found after traversing the prefix list, an error is reported and the program exits.

[0087] After completing the setting of the custom prefix, the tool will parse the message to be parsed based on the current parsing structure until the parsing is completed.

[0088] Specifically, Figure 3As shown, first determine the self-loop attribute (Sub_Self_Repeat) and self-loop merge attribute (Repeat_Combine) of the current parsing structure. If the self-loop attribute is "Y" and the self-loop merge attribute is not "Y", the tool will update the first prefix in the prefix list (i.e., the current prefix) according to the number of self-loops (to ensure that each variable name is unique during the loop). It should be noted that when there is a loop and the self-loop merge attribute (Repeat_Combine) is Y, this structure uses the same variable name for each loop during the loop processing. The next loop process will update the result of the previous loop, and finally form a set of variables and values. When the self-loop merge attribute (Repeat_Combine) is N, the field of the number of loops will be added to the variable name for each loop to ensure that the variable name will not be repeated, so as to obtain each variable and value for each loop.

[0089] Then, it is determined whether the loop number definition byte attribute is defined; it is determined whether the current parsing structure defines the loop number definition byte attribute (NumberByte). If the attribute is not defined, the tool will parse each key value in turn according to the current parsing structure; if the attribute is defined, the part will be extracted and parsed according to the number of bytes defined by the attribute, the loop number will be obtained, and the loop parsing will be performed according to the loop number information. Each loop parsing will create a new set of record substructures according to the current loop number, and the key values ​​parsed in turn according to the current parsing structure will be recorded in the substructure.

[0090] After parsing is completed, it is determined whether the self-loop condition parameter attribute (Slef_Repeat_cond_Key) is empty or "-". If the self-loop condition parameter attribute is empty or "-", it indicates that the current structure does not need to be cyclically parsed, and it is believed that the parsing of the parsing structure is completed, then the parsing of the parsing structure is terminated and the parsing result (i.e., parsing data record dictionary) of the parsing structure is returned. If the self-loop condition parameter attribute is not empty or "-", then according to the variable defined by the self-loop condition parameter attribute, in combination with the prefix list, the value of the variable is searched in the parsing data record dictionary, and the expected value defined by the self-loop condition determination method attribute (Self_Repeat_Cond_Method) and the expected value defined by the self-loop condition expected value attribute (Self_repeat_Cond_Value) are judged (the judgment method will be introduced later), if the judgment result is to meet the self-loop condition, then the next cyclic parsing is continued, if the judgment result is not to meet the self-loop condition, it is believed that the cyclic parsing of the parsing structure is completed, then the cyclic parsing of the parsing structure is terminated and the cyclic parsing result of the parsing structure is returned. If an exception occurs during the process of determining whether the self-loop conditions are met, the tool will report an error and exit the analysis.

[0091] Then, the key values ​​contained in the parsing structure are parsed in turn according to the defined key value attributes, such as Figure 4 As shown, the details are as follows:

[0092] First, determine whether the virtual calculation attribute (Virtual_Math) of the current key value is empty or "-". If it is not empty, it means that the current key value is a user-defined virtual parameter. The communication protocol itself does not contain this part, but due to the length of subsequent key values ​​or the number of loops in the protocol, this parameter is set for calculation. The tool calls the logical processing function defined by the virtual calculation attribute to perform data calculation. If the calculation process is normal, the calculation result will be recorded in the parsed data record dictionary, otherwise it will report an error and exit.

[0093] If the virtual calculation attribute (Virtual_Math) is empty or "-", it means that the current key value is part of the communication protocol, then continue to execute the subsequent steps for parsing. It is necessary to first determine the key value length of the current key value according to the parsing length attribute (Msg_length) (the method for determining the key value length will be introduced later).

[0094] Then determine whether the parsing condition parameter attribute (Cond_Key) of the current key value is empty or "-"; if the parsing condition parameter attribute is empty or "-", it means that the current key value needs to be parsed unconditionally, and then continue with the subsequent parsing; if the parsing condition parameter attribute is not empty or "-", it means that the current key value needs to be parsed according to the condition, then according to the variable in the parsing condition parameter attribute, combined with the prefix list, the value of the variable is searched in the parsing data record dictionary, and the judgment method defined by the parsing condition judgment method attribute (Cond_Method) and the expected value defined by the parsing condition expected value attribute (Cond_Value) are judged (the judgment method will be introduced later). If the judgment result is that the parsing condition is met, then continue with the subsequent parsing. If the judgment result is that the parsing condition is not met, then skip the current key value and perform the parsing of the next key value. If an exception occurs during the judgment of whether the parsing condition is met, an error is reported and exited.

[0095] Then determine whether the current key value needs to be parsed in a loop; if it does not need to be parsed in a loop, parse the message to be parsed according to the key value length (to be described later), record the parsing result in the parsing data record dictionary, and then continue to parse the next key value; if it needs to be parsed in a loop, determine the number of loops, and parse the current key value in a loop according to the number of loops. In each parsing, parse the message to be parsed according to the key value length, record the parsing result in the parsing data record dictionary, and continue to parse the next key value after the loop parsing is completed. If an exception occurs during the parsing process, an error is reported and the program exits.

[0096] Specifically, the process of determining whether the current key value requires loop analysis is as follows: if the loop count attribute (Param_Repeat_Time), the loop attribute based on variable value (Repeat_Base_Var), and the special loop algorithm attribute (Repeat_Special) are all empty or "-", and the loop to end attribute (Repeat_Till_End) is not "Y", then it is determined that the current key value does not require loop analysis; if any one of the loop count attribute (Param_Repeat_Time), the loop attribute based on variable value (Repeat_Base_Var), and the special loop algorithm attribute (Repeat_Special) is not empty or "-", or the loop to end attribute (Repeat_Till_End) is "Y", then it is determined that the current key value requires loop analysis.

[0097] In the case where loop parsing is required, the number of loops is determined as follows: if the loop number attribute (Param_Repeat_Time) is not empty or "-", the value of the variable defined by the loop number attribute is determined as the loop number; if the loop attribute based on variable value (Repeat_Base_Var) is not empty or "-", the variable defined by the loop attribute based on variable value, combined with the prefix list, is searched for the value of the variable in the parsed data record dictionary, and the value of the variable is used as the loop number; if the special loop algorithm attribute (Repeat_Special) is not empty or "-", data calculation is performed according to the logic processing function defined by the special loop algorithm attribute, and the calculation result is used as the loop number; if the loop to end attribute (Repeat_Till_End) is "Y", the loop number is set to -1. It should be noted that, under normal circumstances, the key value of the loop to end attribute set to Y should be the last key value of the parsed structure.

[0098] The current key value is then analyzed in a loop according to the number of loops, as follows: if the number of loops is greater than 0, the current key value is processed in a loop according to the number of loops; if the number of loops is -1, the current key value is processed in a loop until all the information in the current analysis structure is analyzed; if the number of loops is 0, the current key value is skipped and the next key value is analyzed. If the number of loops is other values, an error is reported and the program exits.

[0099] In each analysis, the message to be analyzed is analyzed according to the key value length, and the analysis result is recorded in the analysis data record dictionary, as follows: determine whether the key value length of the current key value is 0; if not 0, extract information from the remaining unextracted information of the message to be analyzed according to the key value length; if 0, extract all the remaining unextracted information of the message to be analyzed. Continue to determine whether the sub-structure attribute of the current key value is empty or "-"; if it is empty or "-", it means that the current key value is an ordinary key value, and the extracted information is recorded in the analysis data record dictionary; if it is not empty "-", it means that the current key value is a composite structure, and the sub-structure defined by the sub-structure attribute (Sub_Struct) is called to analyze the extracted information, and the analysis result is recorded in the analysis data record dictionary.

[0100] Wherein, the structural attribute of the substructure includes: bit structural attribute. Then the substructure defined by the substructure attribute is called to parse the extracted information, including: if the bit identification attribute of the substructure is "Y", indicating that the substructure is a bit type structure, the extracted information is converted into bit type data, and then the substructure is recursively called for parsing; if the bit identification attribute is "N", indicating that the substructure is a byte type structure, the substructure is directly recursively called for parsing the extracted information.

[0101] In the above-mentioned judgment of whether the self-loop condition and the parsing condition are met, the judgment method includes the following six cases: ① The judgment method is set to "==", which means judging whether the value of the variable is the same as the expected value. If the same, it is judged to meet the condition, if different, it is judged to meet the condition; ② The judgment method is set to "!=", which means judging whether the value of the variable is different from the expected value. If different, it is judged to meet the condition, if the same, it is judged not to meet the condition; ③ The judgment method is set to "morethan", which means judging whether the value of the variable is greater than the expected value. If greater, it is judged to meet the condition, if not greater, it is judged not to meet the condition; ④ The judgment method is set to "lessthan", which means judging whether the value of the variable is less than the expected value. If less, it is judged to meet the condition, if not less, it is judged not to meet the condition; ⑤ The judgment method is set to "single", which means judging whether the value of the variable is an odd number. If so, it is judged to meet the condition, if not, it is judged not to meet the condition; ⑥ The judgment method is set to "double", which means judging whether the value of the variable is an even number. If so, it is judged to meet the condition, if not, it is judged not to meet the condition. If the judgment method exceeds the above range, it is judged as a processing exception.

[0102] The aforementioned determination of the key value length of the current key value according to the parsing length attribute specifically includes: judging whether the variable defined by the parsing length attribute is of int type; if it is of int type, indicating that the item defines the current key value length, the value of the variable defined by the parsing length attribute is determined as the key value length of the current key value; if it is not of int type, indicating that the item defines a certain variable that has been parsed, and the current key value length needs to be determined by the current value of the variable, then according to the variable defined by the parsing length attribute, combined with the prefix list, the value of the variable is searched in the parsing data record dictionary; if it cannot be found normally, an error is reported and the exit is made; if it is found, the value of the variable is used as the key value length of the current key value.

[0103] Step S103: After completing the parsing of all message types, output the parsed data record dictionary.

[0104] After the parsing of all message types is completed, the parsing data record dictionary has recorded the parsing results of all message types, and thus the parsing data record dictionary is output, completing all parsing of the messages to be parsed.

[0105] The method of the present invention is described below with a specific example. For example, the message to be parsed is: 01 23 4508 89 01 01AA03 00 00 00 01 01 01 01..., and the configuration file is as follows: Figure 5 As shown, the parsing process is as follows:
