Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a data processing method, in an embodiment of the data processing method, referring to fig. 1, the data processing method includes:
step S10, obtaining a target coding format of data to be transmitted, and judging whether the target coding format is a preset first coding format or a preset second coding format, wherein the second digit of each second coding unit in the preset second coding format is less than or equal to the first digit of each first coding unit in the first coding format;
step S20, if the target encoding format is a preset first encoding format, obtaining a format conversion rule between the preset first encoding format and the preset second encoding format;
step S30, according to the format conversion rule, convert the data to be transmitted into the target data encoded in the preset second encoding format.
The method comprises the following specific steps:
step S10, obtaining a target coding format of data to be transmitted, and judging whether the target coding format is a preset first coding format or a preset second coding format, wherein the second digit of each second coding unit in the preset second coding format is less than or equal to the first digit of each first coding unit in the first coding format;
it should be noted that, in this embodiment, the data processing method is applied to a data processing device, where the data processing device may be a PC computer, or a mobile terminal, and when receiving data to be transmitted, obtains a target encoding Format of the data to be transmitted, where the data to be transmitted includes data such as a file, chat content, and a data package, the target encoding Format may be a Unicode (international text encoding standard, a representation rule of a text in a computer) encoding Format, and in addition, the target encoding Format may also be a variable length encoding Format UTF-8(8-bit Unicode Transformation Format), and obtains the target encoding Format of the data to be transmitted, and determines whether the target encoding Format is a preset first encoding Format or a preset second encoding Format, where a second number of each second coding unit of the preset second encoding Format is less than a first number of each first coding unit of the first encoding Format, in this embodiment, since the second number of bits of each second coding unit of the preset second coding format is less than the first number of bits of each first coding unit of the first coding format, and since a general text does not have an excessive bit length, the preset second coding format is adopted for data transmission, so that the waste of resources can be reduced, that is, specifically, the first number of bits of each first coding unit is 16bits (binary number), and each text can be determined only by 8 bits (binary number).
It should be noted that, in this embodiment, the preset first encoding format may be an international text coding standard Unicode encoding format, and the preset second encoding format may be a UTF-8 encoding format, that is, in this embodiment, the first encoding format is a Unicode encoding format, and the preset second encoding format is a UTF-8 encoding format as an example, which is specifically described. In this case, Unicode is a fixed word represented by 2 bytes, and the 2-byte value is called codepoint (code point).
Referring to fig. 2, the step of determining whether the target encoding format is the preset first encoding format or the preset second encoding format includes:
step S11, determining a byte correspondence between the preset second encoding format and the preset first encoding format;
in this embodiment, a byte correspondence between a preset second encoding format and the first encoding format is first determined, specifically, the byte correspondence includes a first correspondence of a number of bytes and a second correspondence of a byte content, where the first correspondence of the number of bytes may be pre-stored (for example, 1-4 bytes are determined to replace 2 bytes in the Unicode encoding format in the UTF-8 encoding format), and the second correspondence of the byte content is determined according to the number of bytes. It should be noted that, a byte of the Unicode encoding format includes 8 bits, and the Unicode encoding format uses 2 bytes to represent a text, so that there are 256 × 256 — 65536 possible texts (such as 65536 english alphabet texts) in two bytes of the Unicode encoding format, because a letter can be represented by only one bit, and the Unicode encoding format uses 16bits, it is obvious that the Unicode encoding format causes vacant space and waste of resources, and if the UTF-8 encoding format is used, a byte can determine to represent a text, which obviously saves resources, and if the UTF-8 encoding format is required to fully express each data of the Unicode encoding format, this can save resourcesIn table 1, if the codepoint encoding format data is between 0 and 127, then because 2 bytes are between 2 and 127, the encoding format data needs to use 1 to 4 bytes to carry 16bits (2 bytes ═ 16bits) of 2 codepoint bytes, as shown in table 1 (the 1 st to 4 th byte xxx part stores bits of codepoint in sequence)8127, which is determined using one byte in the UTF-8 encoding format, if the codepoint range is between 128 and 2048, which is determined using two bytes in the UTF-8 encoding format, and if the codepoint range is other ranges, which is determined using more bytes in the UTF-8 encoding format.
| Total number of bytes | codepoint range | Byte 1 | 2 nd byte | Byte 3 | Byte 4 |
| 1 | U+0000 U+007F | 0xxxxxxx | |||
| 2 | U+0080 U+07FF | 110xxxxx | 10xxxxxx | ||
| 3 | U+0800 U+FFFF | 1110xxxx | 10xxxxxx | 10xxxxxx | |
| 4 | U+10000 U+10FFFF | 11110xxx | 10xxxxxx | 10xxxxxx | 10xxxxxx |
TABLE 1
Step S12, determining the maximum consecutive number of consecutive bytes contained in the second coding unit according to the byte correspondence, wherein the consecutive bytes constitute a single text;
after obtaining the byte correspondence relationship, determining the maximum continuous number of continuous bytes contained in the second coding unit of the preset second coding format, where the continuous bytes refer to a plurality of non-null bytes that collectively form a single text, assuming that the chinese "country" needs to be represented by 4 bytes, the 4 bytes representing the "country" are continuous bytes, assuming that the chinese "home" needs to be represented by 3 bytes, the 3 bytes representing the "home" are continuous bytes, according to the byte correspondence relationship, determining the maximum continuous number of continuous bytes contained in the second coding unit, specifically, determining the maximum continuous number of continuous bytes contained in the second coding unit by a multiple relationship (which may also be by other means, and is not limited herein) between the number of bytes of each second coding unit and the number of bytes of each first coding unit, if it is determined that the maximum continuous number of the continuous bytes included in the coding unit of the preset second coding format is 4, for example, the UTF-8 coding format can represent any data of the Unicode coding format by continuous 4 bytes (it should be noted that, in this embodiment, only 4 bytes are used, and the UTF-8 coding format with any byte length may also be used).
Step S13, acquiring a first text of a target type in the data to be transmitted, and determining a coding unit value of the first text of the target type according to the maximum continuous number;
after the data to be transmitted is obtained, a first text (an English letter or a Chinese character) of a target type of the data to be transmitted is obtained, a coding unit value of the first text of the target type is determined according to the maximum continuous number, if the maximum continuous number is 4, a value (the value is formed by numbers on each bit of a byte) of the first 4 bytes of all bytes corresponding to the data to be transmitted is obtained, and the value of the first 4 bytes is used as a coding unit value (if the data to be transmitted corresponds to 1-3333 bytes, the bytes arranged in a range of 1-4 are selected).
Step S14, determining, according to the coding unit value and a preset mask operation rule, whether the coding format of the first text of the target type is a preset second coding format or a preset first coding format, so as to obtain a first determination result that the first text of the target type is the preset second coding format, or a second determination result that the first text of the target type is the preset first coding format;
after obtaining the coding unit value such as 11110xxx10xxxxxx10xxxxxx10 xxxxxxxx, judging whether the coding format of the first text of the target type is a preset second coding format or a preset first coding format according to the coding unit value 11110xxx10xxxxxx10 xxxxxxxx and a preset mask operation rule, so as to obtain a first judgment result that the first text of the target type is the preset second coding format or a second judgment result that the first text of the target type is the preset first coding format. In this embodiment, since the encoding unit value is obtained once and operated once according to the mask operation rule without performing multiple byte-by-byte processing of the conventional if-else, the determination speed of the second encoding format, such as UTF-8, in the data transmission process can be increased, and the technical problem that the determination speed of UTF-8 is too slow is solved. That is, in the prior art, it is necessary to first determine whether the first byte is correct through if-else, then determine whether the second byte is correct through if-else, and then determine the third byte, etc., so that it is obvious that the efficiency is lower.
Specifically, the step of determining whether the coding format of the first text of the target type is a preset second coding format or a preset first coding format according to the coding unit value and a preset mask operation rule to obtain a first determination result that the first text of the target type is the preset second coding format, or a second determination result that the first text of the target type is the preset first coding format includes:
step S141, taking a first byte corresponding to the first text of the target type as a target index byte, and obtaining a pre-stored target mask value corresponding to the target index byte and a pre-stored first mask operation result corresponding to the target index byte from a pre-set mask table corresponding to the pre-set second encoding format;
the preset mask table is pre-stored with the index byte, the mask value, the mask operation result and each association relationship among the continuous numbers of the continuous bytes contained in each coding unit in the preset second coding format;
in this embodiment, for the second encoding format UTF-8, a preset mask table exists, where the preset mask table is a preset mask table that is pre-stored and has a length of 256 (the longest length of the first byte) and takes the value of the first byte as an index, and in the preset mask table, each association relationship among the index byte, the mask value, the mask operation result, and the consecutive number of consecutive bytes included in each encoding unit of the preset second encoding format is pre-stored, as shown in fig. 2, each element of the mask table includes a mask value mask, a mask operation result flag, and the total number of bytes cnt included in the UTF-8 encoding unit, and the like.

TABLE 2
In this embodiment, a first byte, e.g., E6, corresponding to the first text of the target type is used as a target index byte, a pre-stored target mask value mask (or may be obtained through a byte correspondence relationship) corresponding to the target index byte is obtained from a preset mask table corresponding to the preset second coding format, and a pre-stored first mask operation result, e.g., 0x00808000, corresponding to the target index byte.
Step S142, presetting and operation processing in a mask operation rule are carried out according to the coding unit value and the target mask value, and a second coding operation result is obtained;
and performing preset and operation processing according to the coding unit value and the mask value to obtain a coding operation result, specifically, for the data to be transmitted, the value of n consecutive bytes (including a target index byte) is value, and if value & table [ n ]. mask ═ table [ n ]. flag, the text corresponding to the n consecutive bytes is a UTF-8 coding unit. For example: e6889199, which is 4 continuous bytes of data to be transmitted, wherein if value & table [ n ]. mask ═ table [ n ]. flag is satisfied, E68891 is a UTF-8 coding unit. Note that if table [ E6], mask ═ 0x00C0C000, and flag ═ 0x00808000, n ═ 3 can be determined.
Step S143, if the first mask operation result is consistent with the second encoding operation result, determining that the encoding format of the first text of the target type is a preset second encoding format, and taking the encoding format of the first text of the target type as the preset second encoding format as a first determination result;

If the first mask operation result is consistent with the second encoding operation result, the encoding format of the first text of the target type is judged to be a preset second encoding format, the encoding format of the first text of the target type is the preset second encoding format and is used as a first judgment result, if the first mask operation result is inconsistent with the second encoding operation result, the encoding format of the first text of the target type is judged not to be the preset second encoding format but to be the preset first encoding format, and the encoding format of the first text of the target type is the preset first encoding format and is used as a second judgment result.
Step S15, acquiring all judgment results corresponding to the data to be transmitted, and judging whether the data to be transmitted is in a preset second encoding format according to a first association between the all judgment results and the first judgment result and a second association between the all judgment results and the second judgment result;
acquiring all judgment results corresponding to the data to be transmitted, according to a first association relation between all the judgment results and the first judgment result, a second incidence relation between all the judgment results and the second judgment result judges whether the data to be transmitted is in a preset second coding format, namely the data to be transmitted comprises a plurality of first texts of other target types (determined from the remaining data to be transmitted after the first texts of the target types are removed), and obtains the judgment results corresponding to the plurality of first texts of other target types to obtain all the judgment results, if all the judgment results are the first judgment results, and judging that the data to be transmitted is in a preset second coding format, and if the whole judgment result is the second judgment result, judging that the data to be transmitted is in the preset first coding format.
Step S20, if the target encoding format is a preset first encoding format, obtaining a format conversion rule between the preset first encoding format and the preset second encoding format;
if the target encoding format is a preset first encoding format, a format conversion rule (prestored as shown in table 1) between the first encoding format and the preset second encoding format is obtained, and if the target encoding format of the data to be transmitted is the preset second encoding format, the data to be transmitted can be directly transmitted.
