Matching treatment is carried out with the character stored in the character repertoire that prestores, statistics can be successfully matched to the character of character from character repertoire
Number, and ratio shared in matched character character all in each decoding result is calculated successfully, if decoding result
The number of characters of middle successful match reaches certain threshold value, then it is assumed that decoding result is correct, which is exported and shown.
Herein it should be noted that scheme disclosed in the above embodiment of the present invention, using heuristic determination methods, for solution
Each character in character string after code, judges whether the character belongs to Chinese commonly used word, if the character appears in national language
The paperwork committee《Modern Chinese commonly used word table》In, then the character belongs to Chinese commonly used word；Otherwise, which is not belonging to
Chinese commonly used word.Finally, the ratio of commonly used word in the character string is counted, if the ratio is more than some threshold value (rule of thumb, threshold
It is preferable that value is arranged on 70%~80% effect), then it is assumed that transformed character string is correct, otherwise it is assumed that transformed word
Symbol string is incorrect.
Optionally, still by taking above-mentioned data to be restored is the character strings " Ke Extern Cong Nao Fan Da " of mess code as an example, it is based on when using
The encryption algorithm of GBK coding rules is encoded the character string of mess code to obtain binary data, and by being based on UTF-8 codings
For the decoding algorithm of rule when being decoded, the decoded result of the binary data is " coding rule ", by the decoding result with
After commonly used word storehouse matching, the character for finding in the decoding result 100% is commonly used word, then it is assumed that decoding result is correct, will decode
As a result export and show.
As a kind of optional embodiment, if multiple decoding results matched with the character to prestore, do not meet
The decoding result of preset condition then exports the prompt message that data to be restored recover failure.
In the above-described embodiments, if being combined the encryption algorithm based on all coding rules by mess code with decoding algorithm
After character string conversion, do not meet the decoding result of preset condition, then illustrate that mess code recovers failure, output mess code recovers failure
Prompt message.

Sequence client) mode be read out, the content format of reading is character string.After reading, mess code character string is transferred to subsequently
Module is handled.
Step S604, judges whether all coding modes were all attempted.
In above-mentioned steps, judge whether the coding mode based on a variety of coding rules all has been used for encoding mess code
For binary data, all have been used for encoding mess code if all of coding mode, then perform step S616；If
In the presence of the coding mode being not attempt to, then step S606 is performed.
Step S606 selects a coding mode do not attempted that mess code is encoded to binary data.
In above-mentioned steps, any one coding mode is selected in the coding mode do not attempted, utilizes coding module
The character string of mess code is converted into binary data.Coding module receives the character string that aforementioned data read module transmits,
According to multiple common Chinese character coding rules such as UTF-8, UTF-16, GBK, GB2312, the character string received is encoded,
Coding the result is that binary data.
Step S608, judges whether all decoding processes were all attempted.
In above-mentioned steps, judge whether the decoding process based on a variety of coding rules all has been used for decoding, if
All decoding processes all have been used for being decoded binary data, then perform step S604；If there is not tasting
The decoding process tried then performs step S610.
Step S610 selects a decoding process do not attempted that binary data is decoded as character.
In above-mentioned steps, any one decoding process is selected in the decoding process do not attempted, utilizes decoder module
Binary data is converted into character string.Decoder module receives the binary data that afore-mentioned code module transfer comes, according to
The binary data received is decoded by multiple common Chinese character coding rules such as UTF-8, UTF-16, GBK, GB2312,
It is decoded the result is that character string.
Herein it should be noted that the coding rule that the coding rule that the decoder module uses is used with afore-mentioned code module
It is different.For foregoing each coding, to attempt strictly all rules and be decoded.
Step S612 judges whether transformation result is correct using heuristic.
In above-mentioned steps, judge whether transformed character string is correct using heuristic judgment module.This is heuristic to sentence
Disconnected module receives the character string decoded in a manner that foregoing decoder module transmits.For each word in character string
Symbol, judges whether the character belongs to Chinese commonly used word, if the character appears in State Language Work Committee《The modern Chinese
Language commonly used word table》In, then the character belongs to Chinese commonly used word；Otherwise it is assumed that the character is not belonging to Chinese commonly used word.Finally, unite
The ratio of commonly used word in the character string is counted, if the ratio is more than that (rule of thumb, which is arranged on 70%~80% to some threshold value
Effect is preferable), then it is assumed that the character string of conversion is correct, otherwise it is assumed that the character string of conversion is incorrect.
Step S614 exports transformation result.
In above-mentioned steps, if the character string of conversion is correct, the character string after being repaired using output module output can
By by being exported in a manner of identical with data read module.
Step S616 prompts repairing failure.
In above-mentioned steps, all fail if the attempt to the combination of all encryption algorithms and decoding algorithm carries out mess code reparation,
Then export the prompt message of repairing failure.
In scheme disclosed in the above embodiments of the present application, read mess code first, attempt by all coding modes with
The combination of decoding process is converted, and transformed character is judged, if correctly, the character after output turn；If
It is incorrect, it tries the combination of other encryption algorithms and decoding algorithm was all attempted if all of combination, then explanation turns
It changes unsuccessfully.
Following technique effect can be realized by above-described embodiment：Mess code is required no knowledge about when carrying out mess code Fault recovery
Original coding, but recovered by attempting various coding modes；Whether judge restoration result using heuristic
Correctly, without manually determining, efficiency is very high when character string is more.
