In actual applications, often there is such demand: valuable information in one section text is extracted, and stored by the form of key-value pair.For example, pending text is " icbc001,123456 ", has wherein hidden channel numbering (api) and the such information of serial number (no), and needs general contents extraction wherein out, finally forms following key-value pair { api:icbc001, no:123456}.
Form to pending text is analyzed, and can learn that text is the character string of separating by a set symbol, comprises irregular separator in text.Therefore with reference to existing string operation method, become key-value pair need to use the mode of obtaining substring text resolution, wherein obtain reference position and the final position of substring in text that substring need to be known extraction in advance; In addition, also need to know the position of separators such as ", "; At two substrings of separator place intercepting, and assignment can obtain key-value pair to corresponding variable.
According to above-mentioned parsing thought, the existing mode that becomes the method for key-value pair mainly to adopt character of a character to process text resolution, detailed process is as follows:
At first, for pending text, from first character, start to search backward, the neither one character is arranged is ", " in judgement, finds after this symbol the position that obtains this symbol place;
Secondly, according to the position of ", " that obtain, know reference position and the final position of substring in whole character string of ", " front, and, reference position and the final position of the substring of back in whole character string;
Again, the function of the extraction substring by programming language extracts respectively this two substrings;
Finally, two substrings are distinguished to assignment to api and no.
To sum up, existing text resolution is become to the method for key-value pair need to carry out a character of a character to text search to determine text formatting, and after searching, need to determine the variable form according to complicated text formatting, then after definite variable form, character string that need to these variablees are corresponding extracts, then by its assignment, form key-value pair, also have now and become the method for key-value pair to need full dose traversal many times text resolution.For example, yet for example, text formatting very complicated (having multiple separator), and, in the situation of text size very long (substring length is very long), repeatedly the full dose traversal can cause declining to a great extent of analyzing efficiency.

The text resolution template of step 101, preset text formatting; Described text resolution template is for describing the form of pending text and the form of target key-value pair;
In the embodiment of the present application, text resolution template itself is also a kind of self-defining programming language, and this language is form for describing pending text and the form of target key-value pair.
In a kind of application example of the application, described text resolution template specifically can comprise definition statement and retain output statement two parts, wherein, definition statement can be used for describing the form of pending text, retains the form that output statement can be used for describing the target key-value pair.
In actual applications, can be by the programmer of the art according to the form situation of pending text and the form situation of target key-value pair, preset described text resolution template.
With reference to table 1, show definition statement and the example that retains output statement in a kind of text resolution template of the application.
Table 1
The text resolution template is comprised of the several rows text, computer program can not Direct Recognition these styles of writing this, computer program is discernible is the data structure (as class object etc.) in internal memory, therefore at first the embodiment of the present application is compiled into described text resolution template the discernible compiling result of computer program.Described compiling result specifically can comprise following content: with the corresponding source variable of the form of pending text and separator, and with the corresponding target variable of the form of target key-value pair, particularly, which source variable is arranged in pending text, what separator between source variable is, the position at separator place, the target variable that final target key-value pair need to retain have which etc.
In a preferred embodiment of the present application, the data structure of described compiling result is class object.Wherein, an attribute of class object can comprise the Map data structure, the Map data structure here is a kind of synonym that calls the turn the key-value pair data structure at program design language, the character string expression method of this data structure is the { form that key=value} is such, for example " 123=abc, 456=def} ".Like this, just the content of compiling result can be saved in the Map data structure.
In order to realize above-described compiling content, the compilation operations that need to carry out is for resolving every a line of text resolution template, reads every a line and meets any in set syntactic structure.Find meet any after, the content of preserving this row in the text resolution template according to the internal storage structure of this grammer body.Such as if which identification variables is the such definition statement of #define () will comprise out in this definition statement, separator is which type of identifies, and the information identified is saved in the Map data structure.
According to the principle of above-mentioned compilation operations, in a preferred embodiment of the present application, described text resolution template specifically can comprise the several rows text; The described template of the text resolution to described text formatting is compiled, and obtains the step of the discernible compiling result of computer program, may further include:
Steps A 1, read this content of style of writing of described text resolution template;
Steps A 2, determine the set syntactic structure that this content of described style of writing meets; Described set syntactic structure specifically can comprise the definition syntactic structure and retain syntactic structure;
Steps A 3, from this content of the described style of writing that meets described definition syntactic structure, identify and the corresponding source variable of the form of pending text and separator;
Steps A 4, from this content of the described style of writing that meets described reservation syntactic structure, identify and the corresponding target variable of the form of target key-value pair.
The template of text resolution shown in table 1 of take is example, the process of corresponding compilation operations can comprise: the text that reads every a line in the text resolution template, the text formatting of every a line is defined as defining syntactic structure and retains the wherein a kind of of syntactic structure Four types, wherein
Definition syntactic structure #define (), determine that the source variable of appointment in this section text definition specifically can comprise: api, action and state, the separator of text definition is ", ", only has this kind of;
Retain syntactic structure #keep (), determine that the target variable that need to finally be retained specifically can comprise :@api@and@action@.
Described above is exactly the process of compilation operations, and after carrying out above-mentioned compilation operations, the application can be saved to the internal storage data structure by compiling accordingly result, at this, provides the example of an internal storage data structure:
{“vars”:[“api”,“action”,“state”],“keepVars”:[“api”,“action”],“replaceStrArray”:[“,”,“,”,]}
Wherein, " vars " for storing source variable orderly, " keepVars ", for storing target variable orderly, " replaceStrArray " is for storing separator orderly; In the situation that specified otherwise not, the order in the embodiment of the present application and order are for meaning the character such as source variable, target variable or the character string sequence of positions at text.
Provide an application scenarios that text resolution is become to key-value pair at this: system for settling account sends to governor's system by the business flowing water information generated, need governor's system to be monitored for these business flowing water information, the pending text wherein sended over is " icbc001, CREATED, S ".Governor's system can become key-value pair by this section pending text resolution, then is saved in pending message queue.System for settling account will be taken out the message body of these key-value pairs from pending message queue, then carries out.Because governor's core processing engine need to use the message of key-value pair form, so all pending flowing water texts all will be extracted into key-value pair.
In a preferred embodiment of the present application, the described source variable of described foundation and separator are mated in pending text, obtain the step of the value of described source variable, may further include:
From the first character of pending text, order according to described source variable and separator is mated in pending text, in the matching result obtained, the value that first character be first source variable to the text between first separator, the value that the text between two separators be correspondence source variable sequentially.
Example on foundation, " vars " stored source variable orderly, " replaceStrArray " stored separator orderly, suppose that pending text is the " icbc001 in above-mentioned application scenarios, CREATED, S ", so, can in pending text, mate, text " icbc001 " between first character and first separator is exactly the value of first source variable " api ", text " CREATED " between first separator and second separator is exactly the value of second source variable " action ", text " S " between second separator and the 3rd separator is exactly the value of the 3rd source variable " state ".
The source variable that step 104, reservation are identical with described target variable and corresponding value, as with the corresponding key-value pair of described pending text.
Owing to describing the span that target key assignments centering major key is arranged in the text resolution template, and resolve and obtained corresponding target variable according to the text resolution template, finally we need " api " and " action " these two variablees.Therefore step 104 can be screened the value of the source variable that gets at present, removes unwanted source variable, what finally retain is exactly { api:icbc001, the key-value pair result that action:CREATED} is such.
With reference to Fig. 2, show a kind of process flow diagram that text resolution is become to the embodiment of the method 2 of key-value pair of the application, specifically can comprise:
The text resolution template of step 201, preset text formatting; Described text resolution template is for describing the form of pending text, the form of target key-value pair and the data check rule of parsing;
The source variable that step 205, reservation are identical with described target variable and corresponding value, as with the corresponding key-value pair of described pending text.
In some cases, in resolving, may exist the expansion of data check to resolve demand, these data checks are the certain data check rule of correspondence usually, and for example, the value of a data verification rule predetermining source variable can not be character "-" etc.
With respect to embodiment of the method 1, the present embodiment adopts the text resolution template to describe the data check rule of resolving, compiling obtains and the corresponding source variable of described data check rule and corresponding verification function, and utilizes the verification function to carry out verification to the value of described source variable.
In a kind of application example of the application, described text resolution template specifically can comprise definition statement, retain output statement and verification statement three parts, wherein, definition statement can be used for describing the form of pending text, retain the form that output statement can be used for describing the target key-value pair, the verification statement can be used for describing the data check rule of resolving.
In a preferred embodiment of the present application, the verification statement can corresponding regular expression.Regular expression is for carrying out the instrument of text matches, usually some common characters and some metacharacters (metacharacters), consists of.Common character comprises the letter and number of capital and small letter, and metacharacter has special implication.The coupling of regular expression can be understood as, and in given character string, finds the part be complementary with given regular expression.Can judge very easily by regular expression whether pending text meets the form of text resolution template regulation.For example, an example of verification statement is, state==regex (S|F), its implication need to meet regular expression " S|F " for " state " variable, if do not meet, verification is not passed through, pending text does not meet form; Also, while only having value corresponding to " state " variable to meet regular expression " S|F ", the corresponding pending text resolution of " state " variable value out just can be retained.
In a preferred embodiment of the present application, described text resolution template specifically can comprise the several rows text; The described template of the text resolution to described text formatting is compiled, and obtains the step of the discernible compiling result of computer program, may further include:
Step B1, read this content of style of writing of described text resolution template;

Step B4, from this content of the described style of writing that meets described reservation syntactic structure, identify and the corresponding target variable of the form of target key-value pair;
Step B5, from this content of the described style of writing that meets described verification syntactic structure, identify and the corresponding source variable of described data check rule and corresponding verification function.
Suppose that step B5 determines the described style of writing content originally that meets described verification syntactic structure :@state@==regex (S|F), can therefrom identify source variable to be verified and be "==" left side " state ", need to use the mode of regular expression to be verified, the verification function corresponding with regular expression is regex (S|F).In actual applications, recognition result can be stored to corresponding internal storage data structure, being exemplified as of an internal storage data structure { " equal ": { " state ": [" regex (S|F) "] } }.
Step 204 is used the verification statement of equal the inside to be processed, and variable to be verified is " state ", according to verification statement regex (), means to need by the regular expression verification.Then, after corresponding value is carried out verification by " state ", if meet the text is extracted successfully, if do not meet the text is abandoned, do not do other processing.Suppose that it is S that step 203 is mated the value that obtains " state " variable, meet the content that regular expression " S|F " is corresponding, can determine that current pending text resolution result out needs, and is retained.
With reference to Fig. 3, show a kind of process flow diagram that text resolution is become to the embodiment of the method 3 of key-value pair of the application, specifically can comprise:
The text resolution template of step 301, preset text formatting; Described text resolution template is for describing the form of pending text, the form of target key-value pair and the secondary data processing demands of parsing;
The source variable that step 305, reservation are identical with described target variable and new variables and corresponding value, as with the corresponding key-value pair of described pending text.
In some cases, in resolving, may exist the expansion that secondary data is processed to resolve demand.For example, if while with the corresponding source variable of the form of pending text, thering is the Map data structure, need to incite somebody to action by secondary treating that { the Map data structure of key=value} is converted into the key-value pair of new variables and corresponding value.
With respect to embodiment of the method 1, the present embodiment adopts the text resolution template to describe the secondary data processing demands of resolving, compiling obtains processing source variable and corresponding new variables and secondary data with the corresponding secondary data of described secondary data processing demands and processes statement, and process source variable and corresponding new variables and secondary data according to the corresponding secondary data of described and described secondary data processing demands and process statement, described source variable and corresponding value are carried out to the secondary data processing, obtain corresponding new variables and corresponding value.
In a kind of application example of the application, described text resolution template specifically can comprise definition statement, retain output statement and secondary data processing statement three parts, wherein, definition statement can be used for describing the form of pending text, retain the form that output statement can be used for describing the target key-value pair, secondary data is processed statement and be can be used for describing the secondary data processing demands of resolving.
With reference to table 2, show the example of definition statement in the another kind of text resolution template of the application, reservation output statement and secondary data processing statement.
Table 2
In a preferred embodiment of the present application, described text resolution template specifically can comprise the several rows text; The described template of the text resolution to described text formatting is compiled, and obtains the step of the discernible compiling result of computer program, may further include:
Step C1, read this content of style of writing of described text resolution template;
Step C2, determine the set syntactic structure that this content of described style of writing meets; Described set syntactic structure comprises the definition syntactic structure, retains syntactic structure and secondary data processing syntactic structure;
Step C3, from this content of the described style of writing that meets described definition syntactic structure, identify and the corresponding source variable of the form of pending text and separator;
Step C4, from this content of the described style of writing that meets described reservation syntactic structure, identify and the corresponding target variable of the form of target key-value pair;
Step C5, process from meeting described secondary data this content of described style of writing of syntactic structure and identify and the corresponding secondary data of described secondary data processing demands is processed source variable and corresponding new variables and secondary data and processed function.
Suppose that step B5 determines the described style of writing content originally that meets the verification syntactic structure :@no@=getMap (Map, no), can therefrom identify secondary data and process source variable " Map ", and corresponding new variables " no ", and secondary data is processed function getMap ().Suppose that pending text is " icbc001, { no=123456}, CREATED, S ", in actual applications, can be by all compiling result stores to corresponding internal storage data structure, be exemplified as { " vars ": [" api " with table 2 and the corresponding internal storage data structure of described pending text, " Map ", " action ", " state "], " keepVars ": [" api ", " no ", " action "], " subStrings ": [" Map "], " mines ": { " no ": [" getMap (Map, no) "] }, " equal ": { " state ": [" regex (S|F) "] }, " replaceStrArray ": [", ", ", ", ", "], wherein, " subStrings " processes source variable for storing secondary data, " mines " processes the corresponding new variables of source variable and secondary data processing function for storing secondary data.
All source variables that step 304 is used the value of preservation in " mines " to obtain coupling carry out the secondary data processing, and the content of preserving in " mines " is { " no ": [" getMap (Map, no) "] }.Syntactic definition according to getMap (), it is " Map " that secondary data is processed source variable, and the character string that " Map " is the Map data type of a kind of java is expressed form: { no=123456}, can there is a major key that variable is " no " in this data type, therefore secondary treating function getMap (Map, no) value corresponding to this " no " major key can be extracted, assignment is given a new variable " no ".
After the secondary treating of step 304, the variable got and respective value specifically can comprise: { api:icbc001, Map:{no=123456}, no:123456, action:CREATED, state:S}.Further, the value of the variable got through step 305 pair is screened, and removes unwanted variable " Map ", and what finally retain is exactly { api:icbc001, no:123456, action:CREATED, the key-value pair result that state:S} is such.
It should be noted that, except the Map data structure, the data structure that described secondary data is processed source variable can also comprise the properties data structure, and also, the text of properties data structure also needs to carry out secondary treating.Similar to the Map data structure, the properties data structure is also a kind of synonym that calls the turn the key-value pair data structure at program design language, but different from the Map data structure is, separation in the properties data structure between each key-value pair is newline, and there is no outmost " { } ", a kind of example of properties data structure is as follows:
123=abc
456=def
Embodiment of the method 2 and embodiment of the method 3 are introduced the parsing scheme that has the expansion parsing demands such as the processing of data secondary data, data check in resolving respectively; In actual applications, except expansion parsing demand, also likely occurring the parsing demand of the continuous changes such as text formatting change in resolving, need frequently, revise in large quantities code in prior art, is also the shortcoming that prior art has very flexible.
And the application separates text resolution template and computer program code (the resolving Chinese version is resolved the computer program code of template and the operational correspondences such as coupling of pending text) by pre-configured mode, when having the parsing demand of constantly change, only need to revise the content of template file, do not need the update routine code fully, configuration mode can accomplish that the residing operating system of program code do not restart so flexibly, and can play the effect of dynamic-configuration; Therefore, therefore, with respect to prior art, the application can improve the dirigibility that text resolution is become to key-value pair greatly.
