Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

[0061] A redemption code is an alphanumeric string that users can enter to receive a specific reward or offer. These rewards may include discounts, virtual currency, exclusive content, or other benefits. Redemption codes are typically issued by merchants or platforms as part of promotional activities and are widely used in various fields, including mobile games, e-commerce platforms, and social media.
[0062] However, the redemption codes generated by the existing technology usually have at least one of the following problems: the redemption code is too long and inconvenient for users to input; the redemption code has limited information carrying capacity; there is a risk that the redemption code is difficult to guarantee its uniqueness; there is a risk of repeated redemption of the redemption code; and there is a risk that the redemption code is easily attacked and cracked.
[0063] Based on this, the embodiments of the present application provide a method and device for generating a redemption code, which can effectively improve the security of the generated redemption code and reduce the risk of being attacked and cracked.
[0064] See also Figure 1 , Figure 1 This is a flow chart of a method for generating a redemption code provided in an embodiment of the present application. Figure 1 As shown in , the generation method provided in the embodiment of the present application includes:
[0065] S101. Obtain multiple target attribute parameters of a redemption code to be generated.
[0066] S102 : For each target attribute parameter, determine the corresponding target encoding length according to the type of the target attribute parameter, and convert the target attribute parameter into a target attribute encoding text of the target encoding length according to the target encoding strategy.
[0067] S103: Obtain the quantity attribute parameter of the redemption code to be generated, and generate the target random number required for generating the redemption code this time according to the quantity attribute parameter and the multiple target attribute parameters.
[0068] S104: Determine a target coding length corresponding to the target random number, and convert the target random number into a target random number coded text of the target coding length according to a target coding strategy.
[0069] S105. Concatenate the target random number encoded text and all target attribute encoded texts in a preset order to obtain a target plaintext.
[0070] S106. Encrypt the target plaintext using a target encryption algorithm based on a preset secret key to obtain a target ciphertext.
[0071] S107: Perform encoding conversion processing on the target ciphertext according to the target encoding strategy to obtain a target redemption code.
[0072] The following describes the exemplary steps of the embodiment of the present application:
[0073] With respect to step S101 , the target attribute parameter is a valid parameter related to the redemption code and can be determined in advance.
[0074] In one embodiment provided by the present application, the multiple target attribute parameters include at least a subject ID, a redemption deadline, and current batch information. The subject ID may also be a product ID.
[0075] In addition, when obtaining multiple target attribute parameters for the redemption code to be generated, parameter verification is required to determine whether all the required multiple target attribute parameters have been obtained. If the verification fails, a verification failure prompt is fed back to the relevant personnel and the redemption code generation process is terminated.
[0076] With respect to step S102 , the target encoding length is the length of a character string obtained after encoding the target attribute parameter using a target encoding strategy.
[0077] For example, the target encoding strategy is a base58 encoding strategy.
[0078] In one embodiment provided in the present application, for each target attribute parameter, determining the corresponding target encoding length according to the type of the target attribute parameter includes:
[0079] S1021. For the topic ID, determine that the target encoding length of the topic ID is a first length.
[0080] S1022. With respect to the exchange deadline, determine a target encoding length of the exchange deadline as a second length.
[0081] S1023. Determine, for the current batch information, that the target encoding length of the current batch information is a third length; wherein the first length, the second length, and the third length are not necessarily the same.
[0082] For step S1021, the first length may be set to a 3-digit string length. Thus, the target encoding length of the subject ID is determined to be a 3-digit string length, and then the subject ID is converted into a target attribute encoding text of a 3-digit string length according to the base58 encoding strategy.
[0083] For step S1022, the second length can be set to a 4-digit string length. In this way, the target encoding length of the redemption deadline is determined to be a 4-digit string length, and then the redemption deadline is converted into a target attribute encoding text of a 4-digit string length according to the base58 encoding strategy.
[0084] For step S1023, the third length can be set to a 1-bit string length. In this way, the target encoding length of the current batch information is determined to be a 1-bit string length, and then the current batch information is converted into a target attribute encoding text with a 1-bit string length according to the base58 encoding strategy.
[0085] It should be noted that when encoding and converting each target attribute parameter according to the target encoding strategy, if any conversion fails, a conversion failure prompt will be fed back to the relevant personnel and the redemption code generation process will be terminated.
[0086] With respect to step S103, the quantity attribute parameter is pre-determined parameter information, specifically representing the total number of redemption codes required to be generated in this batch.
[0087] This step may specifically include: determining the total number of target random numbers required to be generated based on the quantity attribute parameter, and performing cyclic generation of random numbers based on the quantity attribute parameter and the multiple target attribute parameters to obtain at least one target random number (generally multiple target random numbers) required for generating this redemption code.
[0088] With respect to step S104 , the target encoding length corresponding to the target random number may be predetermined, and for example, may be set to a 4-bit character string length.
[0089] This step may specifically include: determining that the target encoding length of the target random number is a 4-bit string length, and then converting the target random number into a target random number encoding text with a 4-bit string length according to the base58 encoding strategy.
[0090] Here, when generating the target random number encoded text, the target random number encoded text is generated for each target random number.
[0091] Among them, if there is a conversion failure when generating any target random number encoding text, the failure is recorded and then the conversion is continued for the next target random number.
[0092] If there are target random numbers that fail to be converted, the number of target redemption codes generated will be less than the required number.
[0093] For step S105, the preset order may specifically be: subject ID coded text + redemption deadline coded text + target random number coded text + current batch information coded text.
[0094] For step S106, in an embodiment provided in the present application, the target plaintext is encrypted using a target encryption algorithm based on a preset key to obtain a target ciphertext, including: obtaining the preset key from a configuration file of the server; and encrypting the target plaintext using an AES encryption algorithm based on the preset key to obtain a target ciphertext.
[0095] Among them, the preset secret key is predetermined static data, and the random number in the plaintext is dynamic data. In this way, the data combined with static and dynamic data is encrypted by the AES encryption algorithm, which can build a multi-level security protection system and effectively prevent the redemption code from being decrypted, tampered with and forged.
[0096] When multiple redemption codes need to be generated, the target ciphertexts obtained by the encryption algorithm may also be multiple.
[0097] Regarding step S107, this step may specifically include performing encoding conversion processing on the target ciphertext according to the base58 encoding strategy to obtain the target redemption code.
[0098] However, when there are multiple target ciphertexts, for each target ciphertext, the target ciphertext is encoded and converted according to the base58 encoding strategy to obtain the target redemption code corresponding to the target ciphertext.
[0099] In addition, in an embodiment provided by the present application, after obtaining the target redemption code, the generation method further includes: storing the target redemption code in a Redis cache of a MySQL database.
[0100] In this way, by utilizing Redis's atomic operations, the atomic use of redemption codes is achieved, ensuring that each redemption code can only be successfully redeemed once, effectively preventing concurrent use and reuse, and achieving excellent performance.
[0101] In another embodiment provided by the present application, after obtaining the target redemption code, the generation method further includes:
[0102] S201: In response to a redemption operation by a user, obtaining a target redemption code and related verification parameters to be redeemed by the user.
[0103] S202: Verify the target redemption code and related verification parameters according to preset rules to determine whether the redemption conditions are met.
[0104] S203: If the conditions are met, the target redemption code is deleted from the database, and a target interface corresponding to a successful redemption of the target redemption code is displayed to the user.
[0105] For step S201, for example, the relevant verification parameters may include: subject ID, open ID, device ID, account ID, etc.
[0106] With respect to step S202, if the redemption conditions are met, step S203 is executed; otherwise, an error message is fed back to the user and the redemption is determined to be invalid.
[0107] Is it true? Step S203, deleting the target redemption code from the database may specifically include deleting the target redemption code from the Redis cache of the MySQL database. For example, the target interface may specifically be an order interface.
[0108] In this way, the present application shortens the length of the target redemption code finally generated through optimized encoding methods and encryption algorithms, thereby improving the user experience; and the present application encodes valid information such as the subject ID and the redemption deadline into the redemption code, thereby improving the information carrying capacity of the redemption code, so that this information can be obtained without additional database queries, greatly reducing the burden on the server; and the present application also ensures that each redemption code is unique by adopting a generation algorithm that combines multiple information such as time information and ID information, fundamentally and effectively eliminating the possibility of repeated generation; and introduces atomic operations (Redis) in the redemption process to ensure that each redemption code can only be used once, effectively preventing concurrent use and reuse; and the present application adopts a high-strength encryption algorithm and a unique encoding method, which makes the redemption code difficult to crack and forge, thereby greatly improving the security of the redemption code and effectively resisting cracking and attacks.
