The technical solution of the present disclosure is explained in detail below with specific examples. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments.
Fig. 1 is a schematic flow chart illustrating a method for transmitting question answer data according to an embodiment of the present disclosure, where as shown in fig. 1, the method includes:
s101, compressing answer data of a questionnaire to be transmitted through a real-time compression algorithm to obtain compressed data;
in practical application, the questionnaire answer data is often transmitted from the cloud server or the database to the client of the user through network transmission, and in the process, the questionnaire answer data is often compressed so as to improve the network transmission efficiency and the encoding and decoding efficiency.
However, in the actual process, different compression algorithms and compression modes lead to different compression results, thereby affecting the overall performance and causing poor user experience.
For example, in the embodiment of the present disclosure, the transmitted question answering data may be compressed by a real-time compression algorithm. Among other things, the real-time compression algorithm of embodiments of the present disclosure may include a Zstandard algorithm.
Optionally, the compression rate and compression/decompression performance of the Zstandard algorithm are outstanding, in the tested text log compression scenario, the compression rate is doubled compared with gzip, and the compression performance is equivalent to or even better than lz4 and snappy, and is more than 10 times of gzip. In addition, the Zstandard algorithm supports the generation of dictionary files in a training mode, and compared with the traditional compression mode, the compression rate of small data packets can be greatly improved.
Step S102, transcoding special characters of the compressed data through a character transcoding algorithm according to the compressed data to obtain transcoded data;
in practical application, the questionnaire answer data to be transmitted is compressed by a real-time compression algorithm to obtain compressed data, only the storage space of the data is changed, but the format of the data does not change, and if the compressed data needs to be transmitted through a network, the compressed data can be transmitted through a Uniform Resource Locator (URL). If it is desired to transmit the compressed data via a URL, the compressed data needs to be encoded in order to be able to meet the format requirements of the transmission.
Illustratively, special characters of the compressed data may be transcoded by a character transcoding algorithm.
In an optional implementation manner, the method for transcoding the special characters of the compressed data through the character transcoding algorithm includes:
converting the compressed data into initial transcoding data through a first coding mode of the character transcoding algorithm according to the compressed data, wherein the first coding mode is used for coding binary data in the compressed data into ASCII code characters;
and converting the initial transcoding data into transcoding data through a second coding mode of the character transcoding algorithm based on the initial transcoding data, wherein the second coding mode is used for coding special characters in the initial transcoding data into general transmission characters.
In an alternative embodiment, the character conversion algorithm includes the Base64Safe algorithm.
It will be appreciated that the Base64Safe algorithm is capable of transmitting 8-bit byte code encodings, and that in the Java Persistence system Hibernate, for example, the Base64Safe algorithm is employed to encode a longer unique identifier (typically a 128-bit UUID) as a string that is used as a parameter in HTTP forms and HTTP GET URLs. In other applications, it is also often necessary to encode the binary data into a form suitable for placement in a URL (including a hidden form field).
In an optional embodiment, the method for converting the initial transcoded data into transcoded data by the second encoding mode of the character transcoding algorithm comprises:
respectively converting the first special character and the second special character in the initial transcoding data into a first general character and a second general character through a second coding mode of the character transcoding algorithm,
the first special character and the second special character need to be transcoded for the second time in the process of transcoding data transmission, and the first general character and the second general character can be used universally in different data.
Illustratively, the standard Base64 algorithm is not suitable for direct transmission in URLs because the URL encoder morphs the "/" and "+" characters in the standard Base64 algorithm into "% XX" and these "%" symbols need to be converted again when stored in the database because the "%" symbols are already used as wildcards in ANSI SQL.
The improved Base64Safe algorithm for URLs used by the disclosed embodiments fills in the' ═ at the end and changes the "+" and "/" in standard Base64 to "-" and "_", respectively, thus eliminating the conversions to be done when URL codecs and databases are stored, avoiding the increase in length of encoded information in the process, and unifying the format of object identifiers at databases, forms, etc.
It is to be understood that the first and second special characters of the embodiments of the present disclosure may be denoted as "+" and "/", respectively, and the first and second general characters of the embodiments of the present disclosure may be denoted as "-" and "_". It should be noted that the meaning of the first special character and the second special character, and the meaning of the first general character and the second general character are not limited in the embodiments of the present disclosure.
And S103, decoding the transcoding data into original question answer data through a decoding algorithm corresponding to the real-time compression algorithm based on the transcoding data, and sending the original question answer data to a target object.
And decoding the transcoded data into original questionnaire answer data based on the transcoding data and a decoding algorithm corresponding to the real-time compression algorithm, so that the information seen by the user is ensured to be the same as the original questionnaire answer data, and the conditions of messy codes and the like are avoided.
Illustratively, the decoding algorithm corresponding to the real-time compression algorithm may be the same algorithm as the real-time compression algorithm, except that the adopted compression and decompression logic is opposite, and in practical application, the decoding algorithm may be that the real-time compression algorithm performs decoding on the receiving end in an opposite action to that of the compression end.
The method for transmitting the answer data of the questionnaire comprises the steps of compressing the answer data of the questionnaire to be transmitted by a real-time compression algorithm to obtain compressed data;
transcoding special characters of the compressed data through a character transcoding algorithm according to the compressed data to obtain transcoded data;
and decoding the transcoded data into original question answer data through a decoding algorithm corresponding to the real-time compression algorithm based on the transcoded data, and sending the original question answer data to a target object.
Only depending on zstd and base64safe, the method can reduce coupling among services by using the mechanism, the compression algorithm is lossless compression, the compression rate and the compression/decompression performance are outstanding, the network transmission efficiency and the coding and decoding efficiency can be improved, and the overall performance is improved.
