Reference herein to "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein may be combined with other embodiments.
Referring to fig. 1, fig. 1 is a flowchart illustrating a first embodiment of a method for parsing a communication protocol according to the present application. Specifically, the method may include the steps of:
s11: and acquiring a data frame and a frame format description file.
It can be understood that, in order to enable data interaction between different modules in network application using different communication protocols to be smoothly performed, when original interactive data, that is, data frames, is acquired at a data relay end, that is, a processing end that forwards data and performs communication protocol conversion, or a data receiving end, the original interactive data needs to be analyzed through a preset processing program to identify which communication protocol is specifically used.
The frame format description file can be understood as an operation program file and a characteristic information file for carrying out communication protocol analysis on the data frame, so that the data frame can be analyzed according to a specific processing flow and a specific framework through the frame format description file.
Specifically, the communication protocol processing terminal obtains data frames sent by other intelligent devices or other functional modules inside the intelligent device, and calls corresponding frame format description files stored locally or in a database, or receives frame format description files input by a user correspondingly.
The frame format description file specifically comprises a frame definition, and the frame definition further comprises a frame field definition, and the frame field definition further comprises a frame field length expression and a frame field decoding expression.
It should be noted that the frame field length expression can be used to calculate the byte length defined by the frame field; and the frame field decoding expression is used to decode the frame field definition into a human readable language.
Optionally, the communication protocol processing terminal may be specifically one of any reasonable intelligent terminals such as a server, a computer, a tablet computer, a smart phone, and a smart watch, which is not limited in this application.
S12: and calculating the length of the frame field defined by the frame field according to the length expression of the frame field.
The frame field length expression may be specifically understood as a function or a program capable of calculating a frame field definition byte length, so that when the data frame and the frame format description file are acquired, the frame field length defined by the frame field can be calculated according to the frame field length expression.
S13: the data frame is parsed into frame field data based on the frame field length.
It can be understood that after the frame field length defined by the frame field is obtained by calculation, the data frame can be decomposed into frame field data with a specific byte length according to the frame field length, so as to facilitate the subsequent analysis processing.
S14: the frame field data is parsed into first human readable language data according to a frame field decoding expression.
Further, the frame field decoding expression may also be understood as an operation program capable of parsing the frame field data into the first human readable language data, so that after the frame field data is obtained, the frame field data may be parsed into the first human readable language data according to the frame field decoding expression, so as to be directly recognized by a user, and the original data content of the data frame and the adopted communication protocol thereof may be interpreted.
According to the scheme, the data frame is analyzed into the frame field data based on the frame field length by calculating the frame field length defined by the frame field, and the frame field data is analyzed into the first human readable language data according to the frame field decoding expression, so that automatic matching can be effectively realized, and a plurality of frame data communication protocols are analyzed and decoded; the data frame is decoded into human readable language, so that the data frame can be directly identified by a user and the original data content of the data frame is read out, and the time for a software developer to adapt to a communication protocol is shortened; and for product maintenance and debugging personnel, the positioning of the problems in the aspect of software and hardware communication can be rapidly assisted.
Further, in an embodiment, the frame field definition further includes a frame field definition name, and after the step S14, the method may further include: storing the frame field definition name, the frame field length, and the first human readable language data to a result set.
It is understood that the result set may be a local configuration storage location, or a storage table in a database. And in order to facilitate subsequent searching, calling and processing, the frame field length and the first human readable language data can be obtained, and the frame field definition name, the frame field length and the first human readable language data can be stored to the result set in a set association mode according to the corresponding frame field definition name.
In another embodiment, the frame definition may further include a frame definition description word and a frame field definition list, and the frame field definition list includes one or more frame field definitions; the frame field definition may further include a frame field descriptor to facilitate more complete parsing of the data frame.
Referring to fig. 2, fig. 2 is a flowchart illustrating a second embodiment of a method for parsing a communication protocol according to the present application. The method for analyzing the communication protocol in this embodiment is a flowchart of a detailed embodiment of the method for analyzing the communication protocol in fig. 1, and includes the following steps:
s21: and acquiring a data frame and a frame format description file.
S21 is the same as S11 in fig. 1, and please refer to S11 and the related text description, which are not repeated herein.
S22: and detecting whether the frame check expression is established.
It can be understood that the frame definition further includes a frame check expression for determining whether the currently acquired data frame belongs to a data type capable of being parsed by the frame format description file, so as to improve parsing efficiency.
Specifically, after the data frame and the frame format description file are acquired, whether a frame check expression in the frame format description file is established or not is detected.
If the frame check expression is true, S23 is executed, and if the frame check expression is not true, it indicates that there is not enough expression for the expression to execute, or the currently acquired data frame cannot be parsed, and a next data frame needs to be acquired, that is, S21 is executed again until the frame check expression is true.
S23: and calculating the length of the frame field defined by the frame field according to the length expression of the frame field.
S24: the data frame is parsed into frame field data based on the frame field length.
S25: the frame field data is parsed into first human readable language data according to a frame field decoding expression.
S23, S24, and S25 are the same as S12, S13, and S14 in fig. 1, and please refer to S12, S13, and S14 and their related text descriptions, which are not described herein again.
Referring to fig. 3, fig. 3 is a flowchart illustrating a third embodiment of a method for parsing a communication protocol according to the present application. The method for analyzing the communication protocol in this embodiment is a flowchart of a detailed embodiment of the method for analyzing the communication protocol in fig. 2, and includes the following steps:
s31: and acquiring a data frame and a frame format description file.
S31 is the same as S21 in fig. 2, and please refer to S21 and the related text description, which are not repeated herein.
S32: and sequentially storing the data frames to a set storage queue according to the acquisition sequence.
The frame format description file further comprises a frame definition list and a frame definition name list, the frame definition list specifically comprises at least one frame definition, the frame definition further comprises a frame definition name, and the frame definition names of the at least one frame definition are specifically stored in the frame definition name list respectively.
The communication protocol processing terminal is pre-configured with a set storage queue, and the set storage queue may be specifically a first-in first-out queue, so that after the data frames are acquired, the data frames can be sequentially stored in the set storage queue according to the acquisition order.
S33: each frame definition is looked up based on a list of frame definition names.
Specifically, for each frame definition name in the list of frame definition names to be detected, the frame definition corresponding to each frame definition name is found in turn.
S34: and detecting whether a frame check expression defined by each frame is established.
Further, after each frame definition is found, the frame check expressions in the frame definition can be sequentially executed to detect whether the frame check expression of each frame definition is true.
It is understood that the frame check expression may specifically be a defined function for accessing the set storage queue, and the function accepts a positive integer as a parameter, where the positive integer represents an index of the set storage queue, and the function is capable of returning the byte content corresponding to the index, that is, the content of the several bytes in the queue, and if the accessed index is larger than the size of the set storage queue, it is determined that there is not enough data for the frame check expression to execute. In this way, whether the frame check expression defined by each frame is established can be sequentially detected.
It should be noted that the frame field length expression mentioned in this embodiment needs to be written in a syntax structure specified by an expression implementation manner, for example, if Lua (scripting language) programming language is used, the frame field length expression needs to be written in the syntax of the Lua programming language, and the frame field expression can specifically calculate and return a result (length, boolean value, or character string) by calling an access function of the set storage queue as a parameter.
Wherein, if there is a frame definition for which the frame check expression is true, traversing the frame field definition list to perform S36 for each corresponding frame field definition, and if the frame check expression is not true, performing S35.
S35: and dequeuing the data frame currently stored in the set storage queue by one byte of data, and acquiring the data frame of one byte again to store the acquired data frame to the set storage queue.
Understandably, if the frame check expression is not true, the frame check expression indicates that there is not enough expression for the expression to execute, and the data frame needs to be stored in the set storage queue continuously; or, the currently acquired data frame cannot be analyzed, and the currently stored data frame of the set storage queue needs to be dequeued by one byte of data, and the data frame of one byte is acquired again, so that the data frame acquired again is stored in the set storage queue.
S36: and calculating the length of the frame field defined by the frame field according to the length expression of the frame field.
S37: the data frame is parsed into frame field data based on the frame field length.
S38: the frame field data is parsed into first human readable language data according to a frame field decoding expression.
S36, S37, and S38 are the same as S23, S24, and S25 in fig. 2, and please refer to S23, S24, and S25 and their related text descriptions, which are not described herein again.
Further, in an embodiment, the step S35 may specifically include: when the frame check expressions defined by each frame are not satisfied, dequeuing all the data frames currently stored in the set storage queue, and acquiring the data frames again to execute S32 again.
Referring to fig. 4, fig. 4 is a flowchart illustrating a fourth embodiment of a method for parsing a communication protocol according to the present application. The resource quota management method of this embodiment is a schematic flow diagram of a detailed embodiment of the resource quota management method in fig. 1, and includes the following steps:
s41: and acquiring a data frame and a frame format description file.
S42: and calculating the length of the frame field defined by the frame field according to the length expression of the frame field.
S43: the data frame is parsed into frame field data based on the frame field length.
S44: the frame field data is parsed into first human readable language data according to a frame field decoding expression.
S41, S42, S43, and S44 are the same as S11, S12, S13, and S14 in fig. 1, and please refer to S11, S12, S13, S14 and their associated text descriptions, which are not repeated herein.
S45: it is detected whether the frame field definition includes a subframe definition list.
It can be understood that, during the data interaction process, there are usually also situations of nested sub-data frames, that is, frames can also be nested in a frame field, and in order to ensure the smooth proceeding of data interaction, for the communication protocol analysis of the data frame, it is also necessary to recursively detect the sub-frames contained in each frame field.
Wherein the subframe definition list includes subframe definitions including one or more subframe field definitions including a subframe field length expression and a subframe field decoding expression.
Likewise, the subframe field length expression can be used to calculate the byte length of the subframe field definition; and a subframe field decoding expression is used to decode the subframe field definition into a human readable language.
Specifically, after the frame field data is parsed into the first human readable language data, it is further detected whether the frame field definition includes a subframe definition list.
Wherein if the frame field definition includes the subframe definition list, S47 is performed, and if the frame field definition does not include the subframe definition list, S46 is performed.
S46: storing the frame field definition name, the frame field length, and the first human readable language data to a result set.
It can be understood that when it is determined that the frame field definition does not include the sub-frame definition list, it can be determined that no nested frame exists in the currently received data frame, and therefore, the frame field definition name, the frame field length, and the first human readable language data are directly stored in the result set.
S47: and calculating the length of the subframe field defined by the subframe field according to the length expression of the subframe field defined by the subframe.
The subframe field length expression may be specifically understood as a function or a program capable of calculating a subframe field definition byte length, so that when a data frame and a frame format description file are obtained, a subframe field length defined by a subframe field may be calculated according to the subframe field length expression.
S48: and resolving the data frame into subframe field data based on the subframe field length.
It can be understood that after the length of the subframe field defined by the subframe field is obtained by calculation, the data frame can be decomposed into the subframe field data with the specific byte length according to the length of the subframe field, so as to facilitate the subsequent analysis processing.
S49: the sub-frame field data is parsed into second human-readable language data according to the sub-frame field decoding expression.
Specifically, the subframe field decoding expression may also be understood as an operation program capable of parsing the subframe field data into the second human-readable language data, so that after the subframe field data is obtained, the subframe field data may be parsed into the second human-readable language data according to the subframe field decoding expression, so as to be directly recognized by a user, and the original data content of the data frame and the communication protocol adopted by the data frame may be interpreted.
Further, in an embodiment, the subfield definition further includes a subfield definition name, and after the above S49, the subfield definition may further specifically include: storing the sub-field definition name, the sub-frame field length, and the second human-readable language data to a result set.
Referring to fig. 5, fig. 5 is a flowchart illustrating a fifth embodiment of a method for parsing a communication protocol according to the present application. The method for analyzing the communication protocol in this embodiment is a flowchart of a detailed embodiment of the method for analyzing the communication protocol in fig. 1, and includes the following steps:
s51: and acquiring a data frame and a frame format description file.
S52: and calculating the length of the frame field defined by the frame field according to the length expression of the frame field.
S53: the data frame is parsed into frame field data based on the frame field length.
S54: the frame field data is parsed into first human readable language data according to a frame field decoding expression.
S51, S52, S53 and S54 are the same as S11, S12, S13 and S14 in fig. 1, and for details, refer to S11, S12, S13 and S14 and their related text descriptions, which are not repeated herein.
S55: it is checked whether the frame field definition includes a list of bit field definitions.
It is understood that in the data exchange process, there are usually also some Bit fields further contained in the frame field, that is, some frame fields contain one or more Bit fields, these Bit fields are represented by less than 1 byte, and the length is represented by using a Bit (Bit), for example, on or off, a 0 or 1 of 1 Bit can be used for representation.
Wherein the list of bit field definitions includes one or more bit field definitions including a bit field length expression and a bit field decoding expression.
In another embodiment, the bit field definition may further include a bit field name and a bit field descriptor to facilitate more complete parsing of the data frame.
Likewise, the bit field length expression can be used to calculate a bit field length value (in bits) for a bit field definition; and a subframe field decoding expression is used to decode the subframe field definition into a human readable language.
Specifically, after parsing the frame field data into the first human readable language data, it is further detected whether the frame field definition includes a list of bit field definitions.
Wherein if the frame field definition includes the bit field definition list, S57 is performed, and if the frame field definition does not include the bit field definition list, S56 is performed.
S56: storing the frame field definition name, the frame field length, and the first human readable language data to a result set.
It can be understood that when it is determined that the frame field definition does not include the bit frame definition list, it is able to determine the bit field not included in the frame field corresponding to the currently received data frame, and therefore it is only necessary to directly store the frame field definition name, the frame field length, and the first human readable language data in the result set.
S57: and calculating the bit field length defined by the bit field according to the bit field length expression defined by the bit field.
The bit field length expression may be specifically understood as a function or a program capable of calculating a bit field definition bit field length value, so that when the data frame and the frame format description file are obtained, the bit field length defined by the bit field can be calculated according to the bit field length expression.
S58: the data frame is parsed into bit field data based on the bit field length.
It can be understood that after the bit field length defined by the bit field is calculated, the data frame can be decomposed into bit field data of a specific bit field length according to the bit field length, so as to facilitate the subsequent analysis processing.
S59: parsing the bit field data into third human-readable language data according to the bit field decoding expression.
Still further, the bit field decoding expression may also be understood as an operation program capable of parsing the bit field data into third human readable language data, so that after the bit field data is obtained, the bit field data may be parsed into the third human readable language data according to the bit field decoding expression, so as to be directly recognized by a user, and the original data content of the data frame and the communication protocol adopted by the data frame may be interpreted.
Further, in an embodiment, the bit field definition further includes a bit field definition name, and after S59, the method may further include: storing the bitfield definition name, the bitfield length, and the third human-readable language data to a result set.
Referring to fig. 6, fig. 6 is a software interface diagram of an embodiment of a method for parsing a communication protocol according to the present application.
