S110, the target barrage data for obtaining preset characters string structure, wherein target barrage data include default separatorWith default connector.
Wherein, barrage data can refer to barrage parameter information is packaged according to default barrage agreement after the word that obtainsThe data of symbol string String type.Default barrage agreement can be preset with user demand according to the actual situation, be used forThe transmission data structure for providing barrage data, so as to can carry out data transmission between barrage server and client.Default bulletCurtain agreement can specify that one or more data structures.Preset characters string structure can be one kind specified in default barrage agreementData structure.Preset characters string structure is corresponding with default barrage agreement.Target barrage data can refer to be verified presetThe barrage data of character string structure.Default separator and default connector are all based on preset characters as defined in default barrage agreementWith the character or character string of specific meanings in string structure.Default separator can be used for dividing barrage parameter information, the company of presettingConnecing symbol can be used for connecting barrage parameter information.Default separator and default connector may each comprise a preset characters,It may include multiple preset characters, wherein preset characters can be a kind of number, letter or additional character predetermined etc..Illustratively, default separator can be used for dividing each key-value pair information in preset characters string structure, such as monocline thick stick " ","/", double slashes " " and " // " etc..Default connector can be used for connecting key information and value information in key-value pair information, thanSuch as "-", "@", ", " "==" and "@=" etc..
Optionally, S110 includes: to obtain barrage data to be verified and the corresponding data to be verified of barrage data to be verifiedMark；Data Identification in Data Identification to be verified logo collection corresponding with preset characters string structure is matched；IfWith success, then barrage data to be verified are determined as target barrage data.
Wherein, barrage data to be verified can be barrage parameter information is packaged according to default barrage agreement after obtainAny data structure barrage data.Each barrage data to be verified correspond to a Data Identification to be verified.Number to be verifiedAccording to mark for carrying out unique identification to barrage data to be verified, can determine barrage to be verified by Data Identification to be verifiedThe data structure of data.The corresponding logo collection of preset characters string structure may include: that data structure is preset characters string structureThe corresponding Data Identification of all barrage data.
It specifically,, can be pre- when generating some barrage data if default barrage agreement defines plurality of data structuresWhether the data structure for first detecting the barrage data of generation is preset characters string structure, if so, the barrage data are correspondingData Identification is added in the corresponding logo collection of preset characters string structure, to be preset characters string by the data structure of generationThe corresponding Data Identification of barrage data of structure is added in the logo collection, to carry out subsequent verification operation.It is obtainingIt, can be by Data Identification to be verified and preset characters string structure pair after taking the corresponding Data Identification to be verified of barrage data to be verifiedThe Data Identification in logo collection answered is matched one by one, if any data mark in Data Identification to be verified and logo collectionKnow successful match, then shows that the data structure of the barrage data to be verified is preset characters string structure, this can be waited for into school at this timeIt tests barrage data and is determined as target barrage data, to carry out completeness check to target barrage data.If data mark to be verifiedIt fails to match with each Data Identification in logo collection for knowledge, then shows that the data structure of the barrage data to be verified is not pre-If character string structure, matching can be identified to next barrage data to be verified at this time, until obtaining preset characters string structureTarget barrage data.
S120, calling store the character string transfer function in the barrage data object of target barrage data, by target barrageData are converted to target character array, and the first character element in target character array is determined as current character element,And the corresponding element position of first character element is determined as current end position.
Wherein, barrage data object is one for storing the object of target barrage data.Target bullet in the present embodimentCurtain data are the data of a String type, so that barrage data object is a String object.Character string transfer functionBe it is predetermined, for target barrage data to be converted to the function of a character array.Character in target character arrayOrder of elements is consistent with the character sequence in target barrage data.Illustratively, if barrage data object is labeled asDanmuStr, then the character string transfer function in danmuStr can be with are as follows: danmuStr.toCharArray (), so as toThe target barrage data stored in danmuStr are converted into target character array.Current character element refers to current targetA character element in character array.Current end position refers to current time corresponding end position.
Specifically, it is assumed that the target barrage data stored in barrage data object danmuStr are as follows: abcd passes through callingThe object of each lower mark of danmuStr is then stored in by danmuStrChar=danmuStr.toCharArray ()In target character array danmuStrChar, i.e. danmuStrChar are as follows: { ' a ', ' b ', ' c ', ' d ' }.The present embodiment can be rightCharacter element in first character array is looped through, to promote calculating speed.In first time cycle period, by targetFirst character element in character array is corresponding by first character element in target character array as current character elementElement position as current end position, current end position at this time is danmuStrChar [0] corresponding position.
Whether S130, detection current character element are default separator, if so, S140 is entered step, if it is not, then enteringStep S150.
It specifically, whether is default separator by detection current character element, it is each in target barrage data to determineThe position of default separator, to obtain the barrage data and every two in target barrage data before first default separatorBarrage data between a adjacent default separator.
S140, current end position is determined as to current start position, and by the corresponding element position of current character elementIt sets and is determined as current end position, and to the first word in target barrage data between current start position and current end positionThe verification that symbol string carries out default connector quantity enters step S150 when the first character string verifies successfully.
Wherein, current start position and current end position refer to two extraction points in current target barrage dataPosition, to extract barrage data (i.e. the first character string) in target barrage data before first default separator or adjacentTwo default separators between barrage data (i.e. the first character string).
Specifically, when current character element is default separator, using current end position as current start position, withCurrent start position is updated, it is current to update then using the corresponding element position of current character element as current end positionEnd position.According to updated current start position and current end position, current start bit in target barrage data is extractedSet the first character string between current end position.Illustratively, in first cycle period, updated current beginningPosition is first character element in target character array, and updated current end position is first in target character arrayThe default corresponding element position of separator, so that the first character string extracted is first default separator in target barrage dataBarrage data before.In second cycle period, updated current start position is first in target character arrayThe corresponding element position of a default separator, updated current end position be in target character array second default separateCorresponding element position is accorded with, so that the first character string extracted is first default separator in target barrage data and secondBarrage data between default separator；Similarly, in subsequent cycle period, the first character string of extraction is target barrageBarrage data in data between two neighboring default separator.
The present embodiment needs to carry out school to the default connector quantity in the first character string after obtaining the first character stringIt tests, to detect the regulation whether the first character string meets default barrage agreement.If the first character string verifies successfully, show targetThe first character string in barrage data is the data of a complete and accurate, can carry out subsequently verification operation at this time.If firstCharacter string verification failure, then show that first character string is a deficiency of data, that is to say, that target barrage data are oneInvalid data can directly determine the failure of target barrage data check at this time, so as to quickly determine out default connectorDiscrepancy of quantity closes defined target barrage data, improves barrage and verifies efficiency.
Whether S150, detection current character element are last character element in target character array, if it is not, then intoEnter step S160, if so, entering step S170.
Specifically, whether it is last character element in target character array by detection current character element, comesWhether determine to loop through terminates.Illustratively, array index number in current character element danmuStrChar [index]The value range of index are as follows: 0≤index≤danmuStrChar.length-1, wherein danmuStrChar.length is indicatedThe length of target character array.
S160, current character element is updated for next character element of current character element, and enter step S130.
Specifically, when current character element is not the last character element in target character array, show to recycleTraversal is also not finished, at this time based on the order of elements in target character array, by the character late element of current character elementIt is updated to current character element, by return step S130, to detect whether character late element is default separator.
S170, the success of target barrage data check is determined.
Specifically, when current character element is the last character element in target character array, show circulation timeEnd is gone through, and the first character string of each of target barrage data verifies success, that is to say, that target barrage data are oneThe data of complete and accurate can determine the success of target barrage data check at this time.
It should be noted that function provided by step S120-S170 can be packaged as a bullet by the present embodimentCurtain verification function, thus only need to be using barrage data object as the input object of barrage verification function, by calling barrage verificationThe checking procedure of target barrage data can be realized in function, so that barrage verification is more convenient.Illustratively, barrage verifies letterNumber can be with is defined as: Publis static Boolean checkDanmInfo (String danmuStr).Wherein,CheckDanmInfo is the function name of barrage verification function, and danmuStr is the barrage data pair of character string String typeAs the return value of barrage verification function checkDanmInfo is the object of boolean's Boolean type.If target barrage numberAccording to verifying successfully, then barrage verification function checkDanmInfo can be by calling return true to return to true, if targetThe failure of barrage data check, then barrage verification function checkDanmInfo can call return false to return to false.BulletCurtain verification function checkDanmInfo has public permission modifier public and static types modifier static, in order toDirectly to call checkDanmInfo by class, the convenience of barrage verification function call is improved.
Optionally, before issuing target barrage data to Android client in barrage server, it can use this implementationThe integrity checking method of barrage data provided by example is verified, and after the success of target barrage data check, then is carried outTarget barrage data issue operation, to guarantee that the target barrage data that barrage server issues are accurate complete data.After Android client receives the target barrage data issued, the complete of barrage data provided by the present embodiment can useProperty method of calibration verified again, and after the success of target barrage data check, then target barrage data are carried out at parsingReason improves barrage test effect so as to avoid leading to problems such as client system crash occur because of barrage data exceptionRate.

Embodiment two
Fig. 2 is a kind of flow chart of the integrity checking method of barrage data provided by Embodiment 2 of the present invention, this implementationExample on the basis of the above embodiments, " in target barrage data between current start position and current end position firstCharacter string carries out the verification of default connector quantity " it is optimized.It is wherein same as the previously described embodiments or corresponding termExplain that details are not described herein.
Referring to fig. 2, barrage data provided in this embodiment integrity checking method the following steps are included:
S210, the target barrage data for obtaining preset characters string structure.
Wherein, preset characters string structure are as follows: using default first symbol as the first character, each key assignments is divided with default separatorTo information, to preset key information and value information in connector connection key-value pair information, using default end mark as ultimate character,Wherein, value information does not include separating character string identical with default separator；When value information includes at least one and default connectionWhen according with identical connection string, the previous character of connection string is default identifier.
In the present embodiment, the first character in accurate complete target barrage data is default first symbol, ultimate characterTo preset end mark, and barrage parameter information exists in the form of key-value pair, i.e., includes between the first character and ultimate characterMultiple key-value pair informations.Illustratively, default first symbol can be but be not limited to left brace " ", left round parentheses " (" or it is leftBracket " [".In order to increase the discrimination between character string body contents, preferably left brace " ".Default end mark canBe but not limited to right brace " ", right round parentheses ") " or right bracket "] ", preferably right brace " ".Preset characters stringDefault separator in structure is used to divide each key-value pair information in barrage data, and default connector is for connecting key-value pairKey information and value information in information.Value information and default end mark in target barrage data in the last one key-value pair informationAlso it can use default separator to be divided, the content for being included so as to distinguishing value.Preset characters string knot in the present embodimentThe prescribed manner of structure can easily facilitate data transmission.
It should be noted that key-value pair information may include English character, Chinese character and/or certain spcial characters.RootAccording to the regulation of default barrage agreement, value information and key information in each key-value pair information will not include and default separator phaseSame separating character string, and the value information in each key-value pair information can not include concatenation character identical with default connectorString also may include connection string identical with default connector, and include at least one and default connection in value informationWhen according with identical connection string, the previous character of each connection string is default identifier.It is default in the present embodimentIdentifier is used to identify a spcial character of connection string in value information, and default identifier is located at connection stringPrior location.Illustratively, default identifier can be but not limited to dollar mark () " " or RMB symbol " ".Each valueConnection string quantity in information is equal with default identifier quantity.
It illustratively, is default separator with "/", with "@if being default end mark with " { " be default first symbol, with " } "=" it is default connector, it is default identifier with " ", then the target barrage data of preset characters string structure can be with are as follows: { type@=0/=uenter/rid@=104838/uid@=20080138/wgei }, including four key-value pair informations, the first keyValue is " type " to the key information in information, and corresponding value information is " uenter "；Key information in second key-value pair information is" rid ", corresponding value information are " 104838 "；Key information in third key-value pair information is " uid ", and corresponding value information is"20080138"；Key information in 4th key-value pair information is " wgei ", and corresponding value information is " 0 ", it is seen then that each key-value pairConnection string identical with default connector is not included in information.The target barrage data of preset characters string structure can also be withAre as follows: { type@=uenter/rid@=104838/uid@=20088/avater@=www@douyu $@=tv@com/ },In key information in the 4th key-value pair information be " avater ", corresponding value information is " www@douyu $@=tv@com ", shouldValue information includes a connection string "@=" identical with default connector and a default identifier " $ ".
S220, calling store the character string transfer function in the barrage data object of target barrage data, by target barrageData are converted to target character array, and the first character element in target character array is determined as current character element,And the corresponding element position of first character element is determined as current end position.
Whether S230, detection current character element are default separator, if so, S240 is entered step, if it is not, then enteringStep S270.
S240, current end position is determined as to current start position, and by the corresponding element position of current character elementIt sets and is determined as current end position, and call the first text string extracting function in barrage data object, extract target barrage numberAccording to the first character string between middle current start position and current end position.
Wherein, the first text string extracting function is predetermined in barrage data object, for extracting target barrage numberAccording to the function of the first character string between middle current start position and current end position.Illustratively, the first text string extractingFunction can be danmuStr.subString (startPos, endPos), indicate the first character in the character string extractedPosition be startPos, the position of last character is endPos-1.
Specifically, what the present embodiment extracted is current start position startPos and current stop bits in target barrage dataSet the first character string between endPos, thus the extraction scope in the first text string extracting function should be (startPos+1,EndPos), so that not including current start position and the corresponding character of current end position in the first character string extracted.
Illustratively, if target barrage data danmuStr are as follows: type@=uenter/rid@=104838/uid@=@=0/ 20080138/wgei }, in first time cycle period, the corresponding call number of updated current start position is 0, whenThe corresponding call number of preceding end position is 13, then by calling danmuStr1=danmu Str.subString (1,13), mentionsThe the first character string danmuStr1 taken is first key-value pair information " type@=uenter " in target barrage data.
It S250, take single character as verification step-length, the adjacent character difference of predetermined number every in the first character string is trueIt is set to the second character string, and determines the default connector quantity in the first character string according to each second character string.
Wherein, predetermined number refers to the character in character quantity adjacent in the first character string, that is, the second character stringQuantity.The sum for the preset characters that predetermined number includes according to default connector and default identifier determines.Illustratively, if in advanceIf presetting connector in character string structure includes X preset characters, presetting identifier includes Y preset characters, then predetermined numberFor X+Y.
Specifically, based on the character sequence in the first character string, it is verification step-length with single character, extracts the first character stringIn adjacent predetermined number character, and the character of extraction is formed into a character string based on the character sequence of the first character string(i.e. the second character string).Similarly, corresponding the second all character string of the first character string can be obtained.Illustratively, if firstCharacter string are as follows: abcd, predetermined number 2, then corresponding three the second character strings of first character string, be respectively as follows: ab, bc andcd.The present embodiment can determine the default company in the first character string according to the default connector quantity in each second character stringConnect symbol quantity.Illustratively, each second character string is matched with default connector and default identifier, if some secondComprising default connector in character string, and it is default identifier before default connector, then shows second character stringIn default connector not instead of real default connector, connection string identical with default connector in value information；If not being default identifier before the default connector in the second character string, show the default connection in second character stringSymbol is really to preset connector for connecting key information and value information, can determine the default company in second character string at this timeConnecing symbol quantity is 1.
If S260, default connector quantity meet default verification condition, it is determined that the first character string verifies successfully, and entersStep S270.
Wherein, it can be obtained: no matter be whether there is in value information by the first string analysis to complete and accurate and default companyThe identical connection string of symbol is connect, the first character string should be there is only one for connecting the default connection of key information and value informationSymbol.That is, default verification condition in the present embodiment can be with are as follows: the default connector quantity in the first character string is 1.
Specifically, if the default connector quantity in the first character string meets default test condition, show the first characterDefault connector in string meets regulation, can determine that the first character string verifies successfully at this time.If default connector quantity is discontentedThe default test condition of foot, then show that the first character string in target barrage data is an invalid data, at this time can directly reallyThe barrage data check that sets the goal failure.
Whether S270, detection current character element are last character element in target character array, if it is not, then intoEnter step S280, if so, entering step S290.
S280, current character element is updated for next character element of current character element, and enter step S230.
S290, the success of target barrage data check is determined.
The technical solution of the present embodiment extracts mesh by calling the first text string extracting function in barrage data objectMark the first character string in barrage data between current start position and current end position；And it is walked with single character for verificationIt is long, the adjacent character of predetermined number every in the first character string is identified as the second character string, according to each second character stringIt determines the default connector quantity in the first character string, and when default connector quantity meets default verification condition, determines theOne character string verifies successfully.The first character string in the present embodiment is regardless of whether include concatenation character identical with default connectorString can use the verification that the method for calibration carries out default connector quantity to the first character string, and then it is suitable to increase verificationWith range, and make barrage verification more convenient, improves verification efficiency.
It based on the above technical solution, include the first preset characters and default connector packet in default identifierWhen including the second preset characters and third preset characters, then S250 may include: to determine the first character in the first character stringFor current character；Based on the character sequence in the first character string, by current character and latter two word adjacent with current characterSymbol is determined as current second character string；If the first character in current second character string is not the first preset characters, and currentSecond character and third character in second character string are the second preset characters and third preset characters respectively, then presetConnector variable is carried out from add operation；Whether detection current character is third last character in the first character string；If so,The default connector quantity variate-value of connector variable being determined as in the first character string；If it is not, then updating current character and beingNext character of current character, and return to execution based on the character sequence in the first character string, by current character and with it is currentLatter two adjacent character of character is determined as the operation of current second character string.
Wherein, when default identifier includes a preset characters, when to preset connector include two preset characters, based on theThree characters of arbitrary neighborhood in the first character string are determined as second character string by the character sequence in one character string, fromAnd available the second all character string.Connector variable is used to store the default connector quantity in the first character string.EvenConnecing symbol variable can be with is defined as: private int Count=0.Wherein, Count is the title of connector variable, and connector becomesAmount Count is the integer variable that an initial value is 0.Connector variable Count has private permission modifier private, withGuarantee only have class belonging to connector variable and its instance object that can just be called.
Specifically, the mode that the present embodiment can use searching loop determines the default connector in each second character stringQuantity, so as to quickly determine the default connector quantity in the first character string.In each cycle period, if currentFirst character in two character strings is not the first preset characters, and second character and third in current second character stringA character is the second preset characters and third preset characters respectively, then shows that current second character string includes one really defaultOtherwise the variate-value of connector variable cumulative 1 can be shown in current second character string and not included real at this time by connectorDefault connector.Then whether detection current character is third last character in the first character string, if so, showing to followRing traversal terminates, at this time connector variable storage be final default connector quantity information, so as to by connectorThe variate-value of variable is determined as the default connector quantity in the first character string；It is also not finished if it is not, then showing to loop through, thenUsing next character of current character as current character, to update current character, to be carried out using updated current characterNext cycle period determines the default connector quantity in next second character string.

Whether S330, detection current character element are default separator, if so, S340 is entered step, if it is not, then enteringStep S390.
S340, current end position is determined as to current start position, and by the corresponding element position of current character elementIt sets and is determined as current end position, and call the first text string extracting function in barrage data object, extract target barrage numberAccording to the first character string between middle current start position and current end position.
It S350, take single character as verification step-length, the adjacent character difference of predetermined number every in the first character string is trueIt is set to the second character string, and determines the default connector quantity in the first character string according to each second character string.
If S360, default connector quantity meet default verification condition, the mesh that connector is preset in the first character string is obtainedMark link position.
Specifically, when default connector quantity meets default verification condition, show in the first character string only comprising oneDefault connector.The present embodiment can be individually determined in the first character string after determining default connector quantity and preset connectorTarget link position, can also be when determining the default connector quantity in the first character string, while determining default connectorTarget link position in the first character string, to improve computational efficiency.
Illustratively, if the first character string danmuStr1 are as follows: avater@=www@douyu $@=tv@com, with "@="It is default identifier with " $ " to preset connector, then will be determined in the first character string danmuStr1 per three adjacent charactersFor second character string, it is seen then that the first character in only one second character string " r@=" is not $, second characterWith third character be respectively@and=, may thereby determine that in the first character string only comprising a default connector, and this is pre-If target link position corresponding call number of the connector in the first character string are as follows: 6 and 7.
S370, calling store the second text string extracting function in the string of the first character string, are connected according to targetPosition is connect, the target value information in the first character string is extracted.
Wherein, string is one for storing the String object of the first character string.Second text string extracting letterNumber be it is predetermined in string, for extracting the function of the target value information in the first character string.Illustratively, wordSymbol string object danmuStr1 in the second text string extracting function can be danmuStr1.subString (startPos,endPos)。
Specifically, the present embodiment can be by calling the length in string danmuStr1 to determine function M=DanmuStr1.length () determines the length M of the first character string of string storage.If default connector only includesOne preset characters, i.e., when target link position Pos1 is only the position of a preset characters, then the second text string extracting functionIn extraction scope should be (Pos1+1, M), so as to extract in the first character string preset connector after character string, andUsing the character string of extraction as target value information.If default connector includes two or more preset characters, basisThe default corresponding target link position of connector determines the corresponding target character position of the last one preset characters in default connectorIt sets, and according to the length of the target character position and the first character string, determines the target value information in the first character string.It is exemplaryGround, if the first character string danmuStr1 are as follows: avater@=www@douyu $@=tv@com is default connector with "@=",Then preset target link position corresponding call number of the connector in the first character string are as follows: 6 and 7 are preset in connectorThe call number of the corresponding target character position of the last one preset characters "=" is 7, the corresponding string length of the first character stringBe 26, at this time can by call string danmuStr1 in danmuStr3=danmuStr1.subString (8,26), the target value information danmuStr3 of extraction are as follows: " www douyu=tv com ".
If S380, target value information are not empty data, it is determined that the first character string verifies successfully, and enters step S390.
Wherein, for the first character string of complete and accurate, the first character string should be a complete key-value pair letterIt ceases, i.e. target value information in the first character string is not centainly sky data.
Specifically, whether detection target value information is sky data, if it is not, then showing that the first character string is a complete keyValue can determine that the first character string verifies successfully, and carry out subsequent verification operation to information at this time；If so, showing firstValue information is lacked in character string, that is to say, that target barrage data are an incomplete data, can directly determine mesh at this timeThe failure of barrage data check is marked, so that the stringency of target barrage data check is improved, so that target barrage data are more completeWhole property, while can also go out lack the barrage data of value information with rapid verification, improve verification efficiency.
Whether S390, detection current character element are last character element in target character array, if it is not, then intoEnter step S391, if so, entering step S392.
S391, current character element is updated for next character element of current character element, and enter step S330.
S391, the success of target barrage data check is determined.
The technical solution of the embodiment of the present invention, the default connector quantity in the first character string meet default verification conditionLater, the second text string extracting function in the string by calling the first character string of storage, according to target connection positionThe target value information extracted in the first character string is set, and guarantees each first by the way that whether detection target value information is sky dataCharacter string includes the value information of a non-empty, and when target value information is empty data, can directly determine target barrageData check failure, so that the stringency of target barrage data check is improved, so that target barrage data have more integrality, andAnd can also go out lack the barrage data of value information with rapid verification, improve verification efficiency.
Based on the above technical solution, before S320, further includes: call the first character in barrage data objectFunction is verified, detects whether the first character in target barrage data is default first symbol；If the first character is default first symbol,The second character in barrage data object is then called to verify function, whether the ultimate character detected in target barrage data is defaultEnd mark；Correspondingly, if it is default end mark that S320, which includes: ultimate character, the barrage number of storage target barrage data is calledAccording to the character string transfer function in object.
Wherein, the first character verifying function is predetermined, for carrying out to the first character in target barrage dataThe function of verification.Second character verifying function be it is predetermined, for carrying out school to the ultimate character in target barrage dataThe function tested.Illustratively, barrage data object is labeled as danmuStr, if default first symbol be " ", default end mark is" ", then call the first character verifying function to can be danmuStr.startWith (" { "), to detect barrage data objectThe first character in target barrage data in danmuStr whether be " "；Second character verifies functionDanmuStr.endWith (" "), to detect the ultimate character in the target barrage data in barrage data object danmuStrWhether be " ".
Specifically, after calling the first character verifying function, if the first character in detection target barrage data is not pre-If first symbol, then show the first character authentication failed, that is, target barrage data are an incomplete data, i.e., it is unqualifiedData can directly determine the failure of target barrage data check at this time.If the first character detected in target barrage data is pre-If first symbol, then show that the first character is proved to be successful, the second character can be called to verify function at this time, detects target barrage dataIn ultimate character whether be that default end mark at this time may be used if it is not, then showing that target barrage data are an incomplete dataTo directly determine the failure of target barrage data check；If so, showing that ultimate character is proved to be successful, i.e., in target barrage dataThe first character and ultimate character be it is legal, can call at this time storage target barrage data barrage data object in wordSymbol string transfer function, to continue to execute subsequent check operation.
The present embodiment, can before the character string transfer function in the barrage data object for calling storage target barrage dataTo verify function and the second character verifying function by the first character in calling barrage data object, respectively to target barrage numberThe first character and ultimate character in carry out character verifying, in the first character authentication failed or ultimate character authentication failedWhen, the failure of target barrage data check can be directly determined；After the first character and ultimate character are proved to be successful, then after carrying outContinuous ground verification operation, so that the stringency of target barrage data check is improved, so that target barrage data have more integrality.
