Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
The product code fetching method provided by the application can be applied to the application environment shown in fig. 1. Wherein the terminal 102 and the server 104 communicate via a network. The server 104 receives a code fetching request initiated by the user based on the terminal 102, and obtains a target code fetching product corresponding to the code fetching request, thereby obtaining a hit rate of the target code fetching product stored in the first-level cache. And when the hit rate of the target code fetching product in the primary cache meets the preset requirement, acquiring the product number of the target code fetching product and a preset splicing prefix for identifying the secondary cache, and splicing the product number and the preset splicing prefix to obtain a code fetching identifier corresponding to the target code fetching product. And then determining a secondary cache corresponding to the target code-fetching product according to the code-fetching identifier, and when the secondary cache is determined to be not empty, extracting the exchange code corresponding to the target code-fetching product from the secondary cache, and feeding the exchange code back to the terminal 102. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, and portable wearable devices, and the server 104 may be implemented by an independent server or a server cluster formed by a plurality of servers.
In one embodiment, as shown in fig. 2, a product code fetching method is provided, which is described by taking the application of the method to the server in fig. 1 as an example, and includes the following steps:
step S202, receiving the code fetching request, and obtaining a target code fetching product corresponding to the code fetching request.
Specifically, when a code fetching request initiated by a user based on a terminal is received, the code fetching request is analyzed, a product number carried by the code fetching request is obtained, and a corresponding target code fetching product is determined according to the product number. The product number and the target code-fetching product have a one-to-one correspondence relationship, and the unique target code-fetching product can be determined according to the product number.
In one embodiment, before receiving a code fetching request and obtaining a target code fetching product corresponding to the code fetching request, the method further includes:
and acquiring each code fetching product determined based on the service requirement and the corresponding hit rate, and storing each code fetching product and the corresponding hit rate into a first-level cache. And acquiring the attribute information of the exchange codes corresponding to the code-fetching products, and storing the attribute information of the exchange codes in a secondary cache.
The corresponding products and the set rules of the hit rates corresponding to the products are different according to the operation popularization requirements of different customers, and the hit rates obtained by different customers according to different product settings are different. The hit rate represents the number of times that the code-taking product is requested to exchange the code, the exchange code is a number consisting of a group of letters and numbers, different suppliers corresponding to different products are different, and the exchange code corresponding to each product is set by each supplier according to own rules.
Similarly, the initial hit rates of different products are preset by the client to which the product belongs, and if each code-fetching product is requested to exchange codes once, the hit rate is increased by 1, and the hit rates of other code-fetching products in the first-level cache are decreased by 1.
Specifically, in this implementation, as shown in fig. 3, fig. 3 provides a corresponding relationship between a first-level cache and a second-level cache, referring to fig. 3, the first-level cache is used for storing a plurality of code-fetching products and hit rates corresponding to the code-fetching products, and functions as a directory, and the second-level cache stores redemption code attribute information corresponding to the code-fetching products, including a redemption code, a redemption code status, a redemption code expiration date, and the like.
And further, only when the target code fetching product needing code fetching and the hit rate of the target code fetching product are determined to be stored in the first-level cache and the corresponding hit rate is determined to meet the preset requirement, the exchange code corresponding to the target code fetching product is further extracted from the second-level cache.
It should be emphasized that, in order to further ensure the privacy and security of the code fetching product, the hit rate corresponding to the code fetching product, and the exchange code attribute information of the code fetching product, the hit rate corresponding to the code fetching product and the exchange code attribute information of the code fetching product may also be stored in a node of a block chain.
And step S204, acquiring the hit rate of the target code fetching product stored in the first-level cache.
Specifically, each code fetching product and the corresponding hit rate are stored in the first-level cache, and the process of updating the hit rate of each code fetching product is further included in the preset updating time period, so that the obtained hit rate of the target code fetching product is the updated current hit rate in the preset updating time period.
Further, the method for updating the hit rate of each code fetching product in the first-level cache comprises the following steps:
acquiring a product number of a target code fetching product carried by the code fetching request; when the target code fetching product exists in the first-level cache according to the product number, increasing the hit rate of the target code fetching product by a preset value, and subtracting the preset value from the hit rates of other code fetching products.
In this embodiment, the preset value may be 1, that is, when it is determined that the target code fetching product exists in the first-level cache according to the product number, the hit rate of the target code fetching product is increased by 1, and the hit rates of other code fetching products in the first-level cache are subtracted by 1, so that the hit rate of each code fetching product in the first-level cache is updated.
In one embodiment, when it is determined that the target code-fetching product does not exist in the first-level cache, the target code-fetching product is added to the first-level cache, the hit rate of the target code-fetching product in the first-level cache is recorded as 1, and the hit rate of other code-fetching products in the first-level cache is subtracted by a preset value 1.
And step S206, when the hit rate of the target code-fetching product in the primary cache is determined to meet the preset requirement, acquiring the product number of the target code-fetching product and a preset splicing prefix for identifying the secondary cache.
Specifically, when it is determined that the hit rate of the target code fetching product in the first-level cache is greater than a preset hit rate threshold, it is determined that the hit rate of the target code fetching product in the first-level cache meets a preset requirement. And then after the hit rate of the target code fetching product in the first-level cache is determined to meet the preset requirement, the product number of the target code fetching product and a preset splicing prefix for identifying the second-level cache are obtained.
And S208, splicing the product number and the preset splicing prefix to obtain a code fetching identifier corresponding to the target code fetching product.
Specifically, since the second-level cache cannot be directly identified according to the product code, a preset splicing prefix that can be used for identifying the second-level cache is also acquired, and the code fetching identifier corresponding to the target code fetching product can be obtained by splicing the product number and the preset splicing prefix.
For example, if the product number corresponding to the obtained target CODE-fetching product is D12345 and the corresponding preset prefix concatenation is a fits _ release _ CODE, the obtained CODE-fetching identifier is D12346-fits _ release _ CODE in combination with the product number and the preset prefix concatenation. It can be understood that the product numbers of different code fetching products are different, but the preset splicing prefix is used for identifying the second-level cache, and the preset splicing prefixes set for different code fetching products can be the same or different.
And step S210, determining a secondary cache corresponding to the target code-fetching product according to the code-fetching identifier.
Specifically, the preset splicing prefix is used for identifying the second-level cache, and the second-level cache corresponding to the target code-fetching product can be determined by further combining the product number.
The second-level cache stores exchange code attribute information corresponding to each code fetching product, wherein the exchange code attribute information comprises an exchange code, an exchange code state, an exchange code validity period, an exchange code expiration period and the like. The state of the exchange code represents whether the exchange code is available or not, the effective period of the exchange code represents the effective time and the effective duration of the exchange code, the expiration period of the exchange code represents the expiration time of the exchange code, and when the expiration time is reached, the corresponding exchange code cannot be reused.
And step S212, when the second-level cache is determined to be not empty, extracting the exchange code corresponding to the target code fetching product from the second-level cache.
Specifically, after the second-level cache of the target code fetching product is obtained, whether the second-level cache is empty or not is judged. And when the second-level cache is determined to be not empty, extracting the redemption code corresponding to the target code fetching product from the second-level cache.
In one embodiment, when the secondary cache is determined to be empty, the redemption code corresponding to the targeted code-fetching product is extracted from the database. Meanwhile, the prompt information that the second-level cache of the target code-fetching product is empty is pushed to a message queue, and the second-level cache of the target code-fetching product is supplemented according to the prompt information, namely, a redemption code state, a redemption code validity period, a redemption code expiration period and the like corresponding to the target code-fetching product are stored in the second-level cache corresponding to the target code-fetching product.
In the product code fetching method, the target code fetching product corresponding to the code fetching request is obtained by receiving the code fetching request, and the hit rate of the target code fetching product stored in the first-level cache is obtained. And when the hit rate of the target code fetching product in the primary cache meets the preset requirement, acquiring the product number of the target code fetching product and a preset splicing prefix for identifying the secondary cache, and splicing the product number and the preset splicing prefix to obtain a code fetching identifier corresponding to the target code fetching product. And then determining a second-level cache corresponding to the target code-fetching product according to the code-fetching identifier, and extracting the exchange code corresponding to the target code-fetching product from the second-level cache when the second-level cache is determined to be not empty. The exchange code is progressively acquired through the arranged first-level cache and the second-level cache, so that the exchange code corresponding to the target code fetching product can be directly acquired from the second-level cache in the memory according to the code fetching request without depending on data to be acquired in real time, the burden of the database is reduced, the occurrence probability of database hot block problems is reduced, and the acquisition efficiency of the exchange code is further improved.
In one embodiment, the method for determining that the hit rate of the target code fetching product in the first-level cache meets the preset requirement specifically includes the following steps:
acquiring preset hit rates of a preset number of standard code fetching products;
arranging preset hit rates of preset number according to the value of each preset hit rate to obtain a preset hit rate queue;
obtaining the minimum hit rate in a preset hit rate queue, and determining the minimum hit rate as a preset hit rate threshold;
comparing a preset hit rate threshold value with the hit rate of a target code fetching product;
and when the hit rate of the target code fetching product is determined to be greater than the preset hit rate threshold value, determining that the hit rate of the target code fetching product meets the preset requirement.
Specifically, the preset hit rates of the preset number of standard code fetching products are obtained, the preset hit rates of the preset number are sorted according to the value of each preset hit rate, a sorted preset hit rate queue is obtained, the minimum hit rate is extracted from the preset hit rate queue, and the minimum hit rate is determined as a preset hit rate threshold. In this embodiment, the preset number is 10, and the ordered preset hit rate queue includes 10 preset hit rates, and the preset hit rate queue is determined as a preset hit rate threshold by extracting a minimum value of the 10 preset hit rates.
Further, by comparing the preset hit rate threshold with the hit rate of the target code-fetching product, when it is determined that the hit rate of the target code-fetching product is greater than the preset hit rate threshold, it is determined that the hit rate of the target code-fetching product meets the preset requirement, that is, it indicates that the product number of the target code-fetching product and the preset splicing prefix for identifying the secondary cache can be further obtained, so that the secondary cache corresponding to the target code-fetching product can be obtained by splicing.
In this embodiment, a minimum hit rate is determined from preset hit rates corresponding to a plurality of standard code fetching products, and the minimum hit rate is determined as a preset hit rate threshold value for comparison with a hit rate of a target code fetching product, and when it is determined that the hit rate of the target code fetching product is greater than the preset hit rate threshold value, it indicates that the hit rate of the current target code fetching product meets a preset requirement. The progressive acquisition based on the first-level cache and the second-level cache is realized, the dependence on a database is not required, the pressure of the database can be reduced, and the acquisition efficiency of the exchange codes is improved.
In one embodiment, a product code fetching method is provided, which comprises the following steps:
in a preset updating time period, obtaining the hit rate of all code fetching products in the first-level cache;
acquiring a preset hit rate threshold;
comparing the hit rate of each code fetching product with a preset hit rate threshold;
and when the code fetching product with the hit rate smaller than the preset hit rate threshold exists, deleting the code fetching product and the corresponding hit rate from the primary cache, and deleting the exchange code attribute information of the code fetching product from the secondary cache.
Specifically, by presetting an updating time period, the hit rates of all code-fetching products in the first-level cache are obtained in the preset updating time period, and the hit rates of all the code-fetching products are compared with the determined preset hit rate threshold value, so that a corresponding comparison result is obtained. And when determining that code-fetching products with the hit rate smaller than a preset hit rate threshold exist in the primary cache according to the comparison result, deleting the code-fetching products and the corresponding hit rate from the primary cache, and deleting the exchange code information corresponding to the code-fetching products from the secondary cache.
The method is characterized in that a first-level cache and a second-level cache are arranged, the exchange codes corresponding to target code fetching products can be directly obtained from a memory without completely depending on a database, and the problem of hot blocks of the database is reduced.
In this embodiment, by comparing the hit rates of all code fetching products in the first-level cache with the preset hit rate threshold, when there is a code fetching product whose hit rate is less than the preset hit rate threshold, the code fetching product and the corresponding hit rate are deleted from the first-level cache, and the exchange code attribute information of the code fetching product is deleted from the second-level cache, so that the number of created caches is reduced, and the burden on the cluster where the current cache is located is reduced.
In one embodiment, a product code fetching method is provided, which comprises the following steps:
recording the current code fetching time of each code fetching product;
acquiring last code fetching time of each code fetching product;
calculating the interval time between the current code fetching time and the last code fetching time;
acquiring a preset code fetching time threshold;
comparing the interval time with a preset code fetching time threshold;
and when the code fetching product with the interval time larger than the preset code fetching time threshold is determined to exist, deleting the code fetching product and the corresponding hit rate from the primary cache, and deleting the exchange code attribute information of the code fetching product from the secondary cache.
Specifically, the current code fetching time of each code fetching request of the code fetching product is recorded, the last code fetching time of each corresponding code fetching product is obtained, the time interval between the current code fetching time of the code fetching request and the last code fetching time is calculated, the interval time is compared with a preset code fetching time threshold value, and a corresponding comparison result is generated. And when the code fetching product with the interval time larger than the preset code fetching time threshold is determined to exist according to the comparison result, deleting the code fetching product and the corresponding hit rate from the primary cache, and deleting the exchange code attribute information of the code fetching product from the secondary cache.
Because different code fetching products and corresponding exchange codes are set based on different business requirements, in actual operation and popularization activities, when hot holidays exist, the code fetching products which are correspondingly popularized are different from the code fetching products which are popularized on normal working days or off-days. After the hot holiday is finished, the code fetching product which is correspondingly specially popularized cancels corresponding popularization operation activities, and it can be understood that the code fetching product does not belong to the hot product popularized in the hot holiday by calculating the time interval between the current code fetching time of the code fetching request and the last code fetching time and comparing the time interval with a preset code fetching time threshold value, when the time interval is determined to be greater than the preset code fetching time threshold value, the code fetching product and the corresponding hit rate are deleted from the primary cache, and the exchange code attribute information of the code fetching product is deleted from the secondary cache.
Further, in one embodiment, the method further comprises:
acquiring the creation time of a second-level cache;
and determining the creation time of the second-level cache as a calculation basis of the protection time of the second-level cache.
Specifically, when a second-level cache of a certain code fetching product is built, the condition of rejecting the cache may be met immediately, and protection time needs to be given to avoid the problem that resources are occupied by frequent operations due to deletion of the second-level cache just after the second-level cache is built. Wherein, the time for creating the secondary cache is recorded as the basis for calculating the protection time.
In this embodiment, by calculating the interval time between the current code fetching time and the last code fetching time, and comparing the interval time with the preset code fetching time threshold, when it is determined that there is a code fetching product whose interval time is greater than the preset code fetching time threshold, the code fetching product and the corresponding hit rate are deleted from the primary cache, and the exchange code attribute information of the code fetching product is deleted from the secondary cache, the number of created caches and the burden on the cluster where the current cache is located can be reduced.

2) And acquiring the attribute information of the exchange codes corresponding to the code-fetching products, and storing the attribute information of the exchange codes in a secondary cache.
The second-level cache stores exchange code attribute information corresponding to each code fetching product, wherein the exchange code attribute information comprises an exchange code, an exchange code state, an exchange code validity period, an exchange code expiration period and the like.
3) And receiving a code fetching request, and acquiring a target code fetching product corresponding to the code fetching request.
