Fig. 2 schematically illustrates a flow diagram of a method of generating a transaction serial number according to an embodiment of the present disclosure.
As shown in fig. 2, the method includes operations S210 to S240.
In operation S210, a serial number generation request is received.
According to an embodiment of the present disclosure, the serial number generation request may be generated by the transaction server and sent to the central server. The serial number generation request is used for requesting the central server to generate a serial number required for the transaction.
The type of transaction serial number requested and the number of digits of the transaction serial number may be included in the serial number generation request. The types of transaction serial numbers may include, for example, numeric types, alphabetic types, and mixed numeric and alphabetic types. Wherein, the numeric type refers to a serial number composed of pure numbers (e.g. 0001), the alphabetic type refers to a serial number composed of pure letters (e.g. efsd), and the alphanumeric type refers to a serial number composed of numbers mixed with letters (e.g. a2b 3).
In operation S220, a target serial number set corresponding to the target serial number type is acquired.
According to the embodiment of the disclosure, each serial number type corresponds to a serial number set, and the serial number set is used for storing the generated serial numbers of the type.
Fig. 3 schematically illustrates an example flow diagram for obtaining a target serial number set corresponding to a target serial number type according to an embodiment of the present disclosure.
As shown in fig. 3, operation S220 may include operations S310 to S320.
In operation S310, a mapping relationship table is acquired.
In operation S320, according to the target serial number type, a target serial number set corresponding to the target serial number type is searched in the mapping relation table.
According to the embodiment of the disclosure, the corresponding relationship between the serial number type and the serial number is stored in the mapping relationship table in advance. The mapping relation table may be, for example, a map data type, and the storage location thereof may be a server memory.
In operation S230, the random generation operation is repeatedly performed to generate the target serial number until the target serial number is not included in the target serial number set.
Wherein the random generation operation comprises: and randomly determining characters on each bit of the target serial number according to the target serial number type and the target serial number digit in the serial number generation request.
According to the embodiment of the present disclosure, the method of generating the serial number differs according to the type of the serial number. For example, in the case where the target serial number type is a numeric type, one numeric character is randomly determined for the character on each bit of the target serial number as the character on the bit. And under the condition that the target serial number type is an alphabetic type, randomly determining an alphabetic character as the character on each bit of the target serial number aiming at the character on the bit. And under the condition that the target serial number type is a digital-letter mixed type, randomly determining each digit of the target serial number as a digital digit or a letter digit, then randomly determining a digital character as a character on the digital digit aiming at each digital digit, and randomly determining an alphabetic character as a character on the letter digit aiming at each letter digit.
For example, for an n-bit serial number, if the serial number is a numeric type, firstly, a random number generation function is executed for a character on the 1 st bit of the serial number (the random number generation function is used for randomly generating any one of 10 numbers of 0 to 9), and any one of 0 to 9 is obtained as the character on the 1 st bit; then, for the 2 nd bit, the random number generation function is run again, and a number is randomly obtained as the character … … on the 2 nd bit, and so on until the character on the n th bit is obtained. For example, the 1 st bit may be the least significant bit.
If the serial number is of a letter type, firstly, a random letter generation function (the random letter generation function is used for randomly generating any one of 26 letters A-Z) is operated aiming at the 1 st character of the serial number to obtain any one of the letters A-Z as the 1 st character; then, for the 2 nd digit, the random number generation function is run again, and a letter obtained randomly is used as the character … … on the 2 nd digit, and so on until the character on the n th digit is obtained.
If the serial number is of alphanumeric type, a random function (random function is used to randomly generate 0 or 1, such as random function) is first run for the 1 st character of the serial number. If the result is 0, the digit is represented as a digital digit, a random digit generation function is operated, and a digit is randomly obtained and used as a character on the 1 st digit; and then, running the random function again, if the result is 1, indicating that the digit is an alphabetical digit, running the random letter generation function, randomly obtaining a letter as the character … … on the 2 nd digit, and so on until obtaining the character on the nth digit.
In operation S240, the target serial number is stored in the target serial number set, and the target serial number is output.
According to the method for generating the serial number provided by the embodiment of the disclosure, the serial number generation request is received, the target serial number set corresponding to the target serial number type in the serial number generation request is obtained, and the random generation operation is repeatedly executed to generate the target serial number until the target serial number is not included in the target serial number set. The method does not need to read the hardware identification in the process of generating serial numbers, and has higher speed. Meanwhile, the generated serial number is random, so that the serial number is not easy to predict, and the safety is high.
It will be appreciated that the above method of generating serial numbers may also be used to generate other numbers, such as account numbers, host communication codes, third party interaction codes, order numbers, etc. requiring unique numbers.
According to another embodiment of the present disclosure, a configuration file may also be preset, where a plurality of serial number templates are preset in the configuration file, for example, as shown in table 1, and each template includes a serial number identifier, a serial number type, and a bit number. The transaction server can send the serial number identifier to the central server through the pipeline generation request, then the central server searches the type and the digit number corresponding to the serial number type from the configuration file, and the corresponding serial number can be generated according to the type and the digit number, so that the transaction server does not need to send the serial number type and the digit number, and the communication overhead can be saved.
TABLE 1
| Identification | Type (B) | Number of bits |
| A | Digital type | 32 |
| B | Mixed type of digit and letter | 18 |
| … | … | … |
The method shown in fig. 2 is further described below with reference to specific embodiments.
The terminal device sends a transaction request to the transaction server. The transaction server judges which type of serial number and how many serial numbers are needed according to the transaction request, correspondingly generates a serial number generation request, and then sends the serial number generation request to the central server.
And after receiving the serial number generation request, the central server analyzes the serial number generation request. And if the serial number generation request contains the serial number identification but does not contain the serial number type and the serial number digit, generating the serial number according to the configuration file. And if the serial number generation request comprises the serial number identification, the serial number type and the serial number digit, generating the serial number according to the serial number type and the digit in the serial number generation request.
And randomly generating each digit character to obtain a digit character string aiming at the serial number type, and then inquiring whether the serial number set corresponding to the serial number identification contains the digit character string in a map in a memory, for example. And if the numeric character string is not contained in the serial number set, taking the numeric character string as a target serial number. If the numeric string is already contained in the serial number set, a numeric string is regenerated until the generated numeric string is not contained in the serial number set.
And aiming at the fact that the serial number type is a pure letter type, randomly generating each letter character to obtain a letter character string, and then inquiring whether the letter character string is contained in the serial number set corresponding to the serial number identification by a map in a memory. And if the alphabetic character string is not contained in the serial number set, taking the alphabetic character string as a target serial number. If the alphabetic character string is contained in the serial number set, an alphabetic character string is regenerated until the generated alphabetic character string is not contained in the serial number set.
Aiming at the fact that the serial number type is a number-letter mixed type, firstly, a result is randomly generated according to a random function, the running result of the random function has two types of 0 and 1, and the occurrence probability is the same and is 50 percent. Then if the operation result is 0, the digit is a digital character, and a digit is randomly generated to be used as a character on the digit; if the operation result is 1, the bit is an alphabetic character, and a bit of alphabet is randomly generated to be used as the character on the bit. Then, map in memory inquires whether the serial number set corresponding to the serial number mark contains the character string. And if the character string is not contained in the serial number set, taking the character string as a target serial number. If the character string is already contained in the serial number set, a mixed alphanumeric character string is regenerated until the generated character string is not contained in the serial number set.

As shown in fig. 4, the method may further include operation S410 in addition to operations S210 to S240.
In operation S410, the serial number generation request is locked such that only the locked serial number generation request is processed at the same time when a plurality of serial number generation requests including the same serial number type are received.
According to the embodiment of the disclosure, the central server judges whether a serial number generation request which is locked by the same type is currently processed. If the locked serial number generation request of the same type is not processed currently, locking the serial number generation request, and then processing; otherwise, the serial number generation request is locked and processed after the locked request is processed and unlocked.
