Embodiment
Many details are elaborated in the following description in order to fully understand the application.But the application can be with
Much implement different from other manner described here, those skilled in the art can be in the situation without prejudice to the application intension
Under do similar popularization, therefore the application is from the limitation of following public specific implementation.
In this application, a kind of method and apparatus for code coding, the method for code decoding are each provided
And device, and a kind of code coding/decoding system.It is described in detail one by one in the following embodiments.
Please refer to Fig.1, it is a kind of flow diagram of embodiment for code coding method of the application.The side
Method includes the following steps：
Step 101：Coding techniques and available code system are selected according to code content to be encoded.
The method of the present embodiment, the content for treating code are encoded, and not as believed in the prior art code
Breath is encoded；In addition exported after the method coding of the present embodiment with image or figure.It is then desired in generation, is encoded according to band
Digital content chooses suitable coding techniques and corresponding code system.That is, in the present embodiment, select the coding techniques that uses and
Optional code system, should mainly meet that following both sides requires：First, the coding result of selected coding techniques can be with figure
Or image mode output；Secondly, the code system in selected coding techniques being capable of alphabet and symbol included in support code.
For example, for a certain section of code, Quick Response Code coding techniques can be selected.Because the output of Quick Response Code coding techniques is
Chequered with black and white rectangle square formation, Quick Response Code coding techniques include QRCode, Data Matrix, Maxi Code, Aztec, QR
A variety of code systems such as Code, Vericode, PDF417, Ultracode, Code49 or Code16K.During if content to be encoded includes
Man's information such as text, may be selected QRCode code systems, because what the 8bit bytes pattern of the code system can be included with support code
Alphabet and symbol, including Chinese character.Certainly, in other embodiments, other coding techniques and code system can also be selected, such as
One-dimension code encodes, and can select the combination of multiple code systems, as long as meeting above-mentioned two condition.
Setting for selected coding techniques and optional code system, can be previously defined in the code for performing code coding method
In, patterned user interface or the control panel with button can also be used, prompts user to make a choice, or is used
Other modes, are not limited thereto.
Step 102, code system is selected, the code content to be encoded is carried out using selected coding techniques and code system
Coding；
After coding techniques is selected, it is also necessary to select a certain code system to treat code and encoded.When selecting code system,
Whether one of problem needed to be considered code system maximum capacity can accommodate code content to be encoded.Specifically, first, can
A kind of code system is selected in code selection system；Code is treated with the code system of selection to be encoded；Next, it is determined that the code length after coding
Whether degree is less than or equal to the maximum capacity of currently used code system, if so, the code after coding is coding result, coding knot
Beam；If it is not, then continuing to select a kind of code system not used to encode code in the optional code system, and continue to compiling
Code after code is compared with corresponding code system capacity, is encoded to until choosing and treating code to available code system
Only.
If, can also be to the generation to be encoded after the maximum capacity for judging a certain code system is less than the length of code to be encoded
Code is compressed, and judges whether the maximum capacity of the code system is not less than the length of code to be encoded again.Wherein, the pressure
Contracting is in order to make source code byte number as small as possible, to meet requirement of the corresponding code system to code length or capacity.Because appoint
What code system is all corresponding capacity limit, has exceeded the capacity, then can not use the code system.With regard to needing to return to unified money
Source finger URL（URL）It is long-range to obtain fetcher code mode.So compression is to accommodate more codes.Compress mode has very
More such as more popular LZ and serial mutation（Deflate, LZW, LZR, LZX）Compression algorithm etc..Compression algorithm can be used
Relatively common compression algorithm.
For example, select the above-mentioned code enumerated for one section of code for including Chinese, optional Quick Response Code coding techniques, code system
System.For example, selection QRCode code systems are encoded.The code to be encoded is read first, is then pre-processed, will wherein
Chinese character encoded according to UTF-8, and coding is resolved into 1-3 byte, each byte is encoded into hexadecimal by ASCII, then
Add " % "（The processing of encodeURIComponent () in similar JavaScript）, then by processed research content into 8
Bit ASCII code.
Code length is obtained, judges whether the code length after coding is less than or equal to the maximum appearance of the code system currently selected
Amount.The max number of characters or byte number that every kind of code system can accommodate are different, such as：The 8bit bytes of QRCode code systems
Pattern can accommodate 2953 bytes, and Data Matrix code systems can accommodate 1556 byte datas.If the code length after coding
Beyond the maximum capacity of selected code system, then can not just generate correct coded graphics or image, or the code pattern of generation
The code information that shape or image include is imperfect.Therefore to check whether the code length after coding is less than or equal to selected code system
Maximum capacity, if it is, labeled as available code system；If not, currently used code system is identified as unusable, Ran Houchong
Duplicate step, attempts to be encoded and judged using other code systems.
For long code, it is possible that the code length after coding is more than the feelings of selected code system maximum capacity
Condition, in addition to other original code systems can be selected to be encoded, it is also an option that being compressed processing to code.
, can be with before carrying out code coding, or when judging that the code length after coding is more than the maximum capacity of currently used code system
Processing is compressed to code, the application is not construed as limiting for the compression method specifically used, as long as being ensured of for code
Lossless compression, and achieve the purpose that shortening code length can.
If in all optional coding techniques and code system, if the capacity of each optional code system, which is respectively less than, encodes post code；Then will
The code uploads onto the server end；Receive the universal resource locator for the record access code resource that server end issues
（URL）；The universal resource locator is encoded.
After suitable coding method and code system are chosen to code content coding, the code after being encoded, or fruit are adopted
Upload code obtains URL to server-side and URL is encoded.That is, the coding result is probably after encoding
Code, or can access and read the URL of code, in coding in the writable coding in the encoded content for encoding generation
Object type, it is code or URL which, which is used for identification code data, in order to being distinguished when code decoding.
Step 103：Coded graphics or image are generated according to coding result and export the coded graphics or image.

Step 304, coded object type after parsing is decoded for the code of code coding, obtains source code.
For the coded graphics or figure formed after the above-mentioned coding to code content, coded graphics or image are parsed
Afterwards, original code can be obtained by carrying out decoding using corresponding coding/decoding method.Specifically, to the number of coded graphics or image
Decoded according to content, be the inverse process of code coding process.For example, above-mentioned encoded using 8 bit ASCII modes, first by number
According to content recovery into the code stream carried out before 8 bit ASCII codings, then identify in code stream whether include Chinese character, if Chinese character,
Just decoded according to UTF-8（Similar to the treated of decodeURIComponenet () function in JavaScript
Journey）, obtain source code.Decoding finishes, and judges whether decoded code includes data compression information, if including data pressure
Contracting information, using with coding when the corresponding decompression algorithm of compression algorithm used, place is unziped it to decoded code
Reason, obtains source code.
In addition, coded graphics or figure are possible to the situation encoded for URL, after being parsed to coded graphics or image,
Judge whether comprising classification information and identify classification, if do not include classification information, or classification is code, then just to coding
The data content of figure or image is decoded, and reduces source code；If if comprising reading is given birth in coding in coding
Into encoded content in writable coded object classification.To comprising classification information be URL situation, illustrate coded graphics or figure
