Description
Technical Field
The present invention relates to the field of communications technologies, and in particular, to a data transmission method, apparatus, electronic device, and medium.
Background
When data interaction is performed between different computer systems or services, data objects to be interacted need to be converted into data transmission data in a transmittable format through data transmission, and the data transmission data can be binary data streams, so that operations such as holding or transmitting the data transmission data can be performed. The application scenarios of serialization and deserialization in actual development include: (1) The object needs to be serialized before network transmission (such as remote method call (RPC)), and deserialization needs to be performed after the serialized object is received; (2) When the object is stored in the file, serialization is needed, and when the object is read from the file, deserialization is needed; (3) Serialization is needed when objects are stored in a cache database (such as Redis), and deserialization is needed when the objects are read out from the cache database.
Serialization refers in the data processing of computer science to the process of converting a data structure or object state into an accessible format (e.g., as a file, in a buffer, or sent over a network) for subsequent restoration of the original state in the same or another computer environment. When the result of retrieving bytes in a serialized format, it can be used to generate a copy of the same semantics as the original object. For many objects, such as complex objects using a large number of references, this process of serialized reconstruction is not easy. Object serialization in object-oriented does not generalize the functions that the original objects previously had in relation to. This process is also referred to as object grouping. The reverse operation, which extracts a data structure from a series of bytes, is deserialization (also known as de-marshalling).
At present, the serialization and deserialization methods have poor flexibility, lack a serialization flow sending strategy corresponding to a corresponding scene, and have low data transmission and processing efficiency.

Based on the hardware structure, the embodiment of the data transmission method is provided.
Referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of a data transmission method of the present invention, where the data transmission method includes:
step S10, acquiring a data object to be serialized, and determining the data type of the data object to be serialized;
s20, serializing the data objects to be serialized on the basis of the data types and the preset coding formats corresponding to the data types to obtain corresponding serialized data; the preset coding format is used for representing serialization modes of data objects aiming at different data types;
and step 30, determining a receiving device corresponding to the data object, and storing and/or transmitting the serialized data to the receiving device.
In this embodiment, a data object to be serialized is obtained, and a data type to which the data object to be serialized belongs is determined; determining a preset coding format corresponding to the data type according to the data type, and serializing the data object to be serialized according to the preset coding format to obtain corresponding serialized data; determining receiving equipment corresponding to a data object to be serialized, and storing and/or transmitting the serialized data to the receiving equipment; thereby realizing cross-platform storage or network data transmission of data.
The respective steps will be described in detail below:
step S10, acquiring a data object to be serialized, and determining the data type of the data object to be serialized.
In this embodiment, for data interaction of different computer systems, for example, the computer system a needs to transmit a data object to the computer system B, and in order to facilitate data transmission between the computer system a and the computer system B, the computer system a needs to serialize different types of data objects to obtain serialized data, where the serialized data may be a binary data stream. The computer system A then transmits the serialized data to the computer system B, and the computer system B deserializes the serialized data to restore the data object.
Acquiring data objects to be serialized from different channels, and identifying data types corresponding to the data objects to be serialized; the data type of the data object to be serialized comprises one or more of positive number, negative number, byte array, single-precision floating point number, double-precision floating point number and character string.
For example, the data objects to be serialized are: BSTP1, NON, POST, QOS0, "/data/carry";
the data objects to be serialized are: "accept", [ "bank/bsc", "bank/bst" ], "Content-Type", "bank/bsc", "Length",72, "Date", 1646817997; the data objects to be serialized are: "GETCMD",187ED5333168, [69, 10, 19, ec, b0,4c, dc, ec,9d, e5, b8, 16,7c, d4, 25, 86]; the data objects to be serialized are: 35, 1, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112, 113, 114.
In the above example, the data object to be serialized is divided into corresponding elementary units by different delimiters; the separator includes: comma (Comma) delimiters ",", delimiters for separating one unit;
semicolon separators "; ", a delimiter for separating a set of elementary units;
the bracket separator "[ ]", the elements in the square brackets are tuples, and the elements in the tuples are separated by comma separators;
the quotation mark separator "" is used, characters in quotation marks are a character string, and reserved keywords are not separated by quotation marks.
S20, serializing the data objects to be serialized on the basis of the data types and the preset coding formats corresponding to the data types to obtain corresponding serialized data; the preset encoding format is used for representing serialization modes of data objects aiming at different data types.
In an embodiment, according to the data type of the data object to be serialized, a preset encoding format corresponding to the data type is determined, and the data object to be serialized is serialized according to the preset encoding format to obtain corresponding serialized data; the preset encoding format is used for representing the serialization mode of the data objects aiming at different data types. For example, if we want to transport a house from one place to another, serialization is that i tear down the house into bricks one by one and put them in a car, then leave a drawing of the original structure of the house, and deserialization is the process of reducing a brick into the original face of the house according to the drawing after we transport the house to the destination.
In addition, comparing the coding format of the data transmission method with the direct coding mode, the byte length of the serialized data obtained by adopting the data transmission method can be detected to be smaller than the byte length of the message data obtained by adopting the direct coding mode, namely, the data transmission method can also reduce the data volume of the transmitted data.
As an example, a segment of message content is extracted as original message data, where the original message data is:
02801408004E0000000000010001010400AF000000000000113000000000038400000BB8000000000000586862A00002F10C000000000000E7BABFE8B7AF310000000000000000000000000000000000；
the definition in the reference message can resolve the actual meaning of the message as shown in the following table:
the message content after BSTP coding is as follows:
FC82800288508E0180808180818404AF02808080B0448080840E80B82E8080A00A43060B8C4417808080FBE7BABFE8B7AF3100FF
the comparison shows that the length of the original message data is 80 bytes, and the length of the original message data converted into the coded message data of the data transmission method is 52 bytes.
Further, in an embodiment, referring to fig. 3, step S20 includes:
step S21, determining a preset coding format corresponding to the data type according to the data type; the data types comprise one or more of positive numbers, negative numbers, byte arrays, single-precision floating point numbers, double-precision floating point numbers and character strings, and each data type corresponds to a specific coding format;
and S22, serializing the data object to be serialized according to a preset coding format to obtain corresponding serialized data.
In this embodiment, according to the data type of the data object to be serialized, a preset encoding format corresponding to the data type is determined. The data type comprises one or more of positive numbers, negative numbers, byte arrays, single-precision floating point numbers, double-precision floating point numbers and character strings, and each data type corresponds to a specific coding format.
Specifically, the preset encoding format includes but is not limited to: positive number encoding format, negative number encoding format, byte array encoding format, single precision floating point encoding format, double precision floating point encoding format, and string encoding format.
After the preset coding format is determined, serializing the data object to be serialized through the preset coding format to obtain corresponding serialized data. Thereby improving the serialization efficiency of the data.
In addition, a declaration identifier corresponding to each data type is inserted into a preset position in the serialized data. For example, when the data object to be serialized is a positive number, a positive number declaration (AC) is inserted at the forefront position in the corresponding serialized data. For example, the serialized data is: FC AC 66 7D, where FC is a positive number specifier.
Referring to table 1, table 1 is a description of reserved keys for serialized data.
Furthermore, since the above-described encoding has a self-partitioning property, in the case where a data object to be serialized triggers sequential encoding, if the same data type exists in the data object to be serialized, the encoding type identifier can be omitted starting from the second data of the same data type. Referring to fig. 4, fig. 4 is a schematic diagram illustrating the effect of continuous coding; the process of data compression by successive encoding "meter", "W/h",2200, 6400, 486, 12 is shown in fig. 4.
And step 30, determining a receiving device corresponding to the data object, and storing and/or transmitting the serialized data to the receiving device.
In this embodiment, a receiving device corresponding to a data object to be serialized is determined, and the serialized data is stored and/or transmitted to the receiving device; wherein the receiving device comprises a computer device or system; thereby realizing cross-platform storage or network data transmission of data.
Further, in an embodiment, after the step S30, the method further includes: and determining a declaration identifier to which the serialized data belongs, and deserializing the serialized data based on a preset decoding format corresponding to the declaration identifier to obtain a data object corresponding to the serialized data.
In this embodiment, after the receiving device obtains the corresponding serialized data, the declaration identifier described in the serialized data is determined; and then, determining a preset decoding format according to the declaration identifier, and then deserializing the serialized data through the preset decoding format to obtain a data object corresponding to the serialized data. Therefore, the serialized data can be restored to the original data object (namely, the data object to be serialized) content through the deserialization operation.
Wherein, the declaration identifier can be used for identifying the data type corresponding to each serialized data, and the declaration identifier is located at the front part of the serialized data; for example, the serialized data is FC AC 66 7D, where FC is the declarative identifier of the serialized data and FC indicates that the serialized data is a positive number.
Each declaration identifier corresponds to a particular (i.e., unique) preset decoding format.
In the embodiment, the data object to be serialized is obtained, and the data type of the data object to be serialized is determined; determining a preset coding format corresponding to the data type according to the data type, and serializing the data object to be serialized according to the preset coding format to obtain corresponding serialized data; determining receiving equipment corresponding to a data object to be serialized, and storing and/or transmitting the serialized data to the receiving equipment; thereby realizing cross-platform storage or network data transmission of data.
Further, a second embodiment of the data transmission method of the present invention is proposed based on the first embodiment of the data transmission method of the present invention.
The difference between the second embodiment of the data transmission method and the first embodiment of the data transmission method is that in this embodiment, for step S22, the data object to be serialized is serialized according to a preset coding format, so as to obtain refinement of corresponding serialized data, and referring to fig. 5, this step specifically includes:
step A10, determining a positive number encoding format corresponding to a positive number under the condition that the data type comprises the positive number;
step A20, based on the positive number coding format, converting the data object to be serialized into corresponding binary data, and performing reverse order separation on the binary data according to a preset decomposition mode to obtain positive number separation data; wherein the positive number separating data comprises a first tuple data and a plurality of second tuple data;
step A30, based on a preset filling mode, respectively filling the high order of the first tuple data and each second tuple data to obtain filled positive data, and converting the filled positive data into corresponding hexadecimal format data;
and A40, arranging the hexadecimal format data according to a small-end mode to obtain arranged positive data, and inserting a positive declaration into a preset position of the arranged positive data to obtain corresponding serialized data.
In the embodiment, in the case that the data type includes a positive number, a positive number encoding format corresponding to the positive number is determined; converting a data object to be serialized into corresponding binary data based on a positive number coding format, and performing reverse order separation on the binary data according to a preset decomposition mode to obtain positive number separation data; the positive number separating data comprises first tuple data and a plurality of second tuple data; respectively filling the high order of the first tuple data and each second tuple data based on a preset filling mode to obtain filled positive data, and converting the filled positive data into corresponding hexadecimal format data; arranging the hexadecimal format data according to a small-end mode to obtain arranged positive data, and inserting a positive declaration into a preset position of the arranged positive data to obtain corresponding serialized data; thereby realizing positive number serialization and improving positive number serialization efficiency.
The respective steps will be described in detail below:
step A10, under the condition that the data type comprises a positive number, determining a positive number coding format corresponding to the positive number.
In this embodiment, in the case that the data type of the data object to be serialized is determined to be a positive number, a positive number encoding format corresponding to the positive number is determined. And the data object to be serialized can be serialized according to the positive number coding format, so that positive number serialization is realized, and the positive number serialization efficiency is improved. Referring to fig. 6, fig. 6 is a schematic diagram of serialization in the case where the data object to be serialized is a positive number; FIG. 6 shows the process of encoding a positive number 1030572, resulting in an encoding of FC AC 66 7D, where FC is the positive number specifier.

In this embodiment, a data object to be serialized is expanded in a binary format according to a positive number encoding format and converted into binary data corresponding to the data object to be serialized; then, carrying out reverse order separation on the binary data in a 6bit + n × 7bit mode to obtain positive number separation data; the positive number separating data comprises first tuple data and a plurality of second tuple data. The first tuple data is 6-bit data, and the second tuple data is 7-bit data.
