Detailed Description
In order to make the objects, technical solutions and advantages of the present application more apparent, the present application will be further described in detail with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the present application.
The code fetching method of the product can be applied to an application environment shown in fig. 1. Wherein the terminal 102 communicates with the server 104 via a network. The server 104 receives a code fetch request initiated by a user based on the terminal 102, and obtains a target code fetch product corresponding to the code fetch request, thereby obtaining the hit rate of the target code fetch product stored in the first-level cache. When the hit rate of the target code-taking product in the first-level cache meets the preset requirement, the product number of the target code-taking product and the preset splicing prefix used for identifying the second-level cache are obtained, and the product number and the preset splicing prefix are spliced to obtain the code-taking identifier corresponding to the target code-taking product. And further determining a secondary cache corresponding to the target code-taking product according to the code-taking identification, and when the secondary cache is determined to be non-empty, extracting the exchange code corresponding to the target code-taking product from the secondary cache, and feeding back the exchange code to the terminal 102. The terminal 102 may be, but not limited to, various personal computers, notebook computers, smartphones, tablet computers, and portable wearable devices, and the server 104 may be implemented by a stand-alone server or a server cluster composed of a plurality of servers.
In one embodiment, as shown in fig. 2, a method for code fetching of a product is provided, and the method is applied to the server in fig. 1 for illustration, and includes the following steps:
step S202, a code fetch request is received, and a target code fetch product corresponding to the code fetch request is obtained.
Specifically, when a code-taking request initiated by a user based on a terminal is received, the code-taking request is analyzed, a product number carried by the code-taking request is obtained, and a corresponding target code-taking product is determined according to the product number. The product numbers and the target code-taking products have one-to-one correspondence, and the unique target code-taking products can be determined according to the product numbers.
In one embodiment, before receiving the code fetch request and acquiring the target code fetch product corresponding to the code fetch request, the method further includes:
and acquiring each code-taking product and the corresponding hit rate determined based on the service requirement, and storing each code-taking product and the corresponding hit rate into a first-level cache. And further acquiring the conversion code attribute information corresponding to each code-taking product, and storing the conversion code attribute information into a secondary cache.
The corresponding products and the set rules of hit rates corresponding to the products are different according to the operation popularization requirements of different clients, and the hit rates obtained by different clients according to different product settings are inconsistent. The hit rate indicates the number of times the code-taking product is requested to exchange the code, the exchange code is a number composed of a group of letters and numbers, 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 rate of different products is preset by the customer to which the products belong, and if each code-taking product is requested to exchange codes once, the hit rate is increased by 1, and the hit rate of other code-taking products in the first-level cache is decreased by 1.
Specifically, in this embodiment, as shown in fig. 3, fig. 3 provides a correspondence between a first-level cache and a second-level cache, and referring to fig. 3, the first-level cache is used for storing a plurality of code-taking products and hit rates corresponding to the code-taking products, which are equivalent to the role of a catalog, and the second-level cache stores exchange code attribute information corresponding to the code-taking products, including exchange codes, exchange code states, exchange code validity periods, exchange code expiration periods, and the like.
Further, only when the target code-taking product and the hit rate thereof which need code-taking are 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-taking product is further extracted from the second-level cache.
It should be emphasized that, in order to further ensure the hit rate corresponding to the code-taking product and the privacy and security of the exchange code attribute information of the code-taking product, the hit rate corresponding to the code-taking product and the exchange code attribute information of the code-taking product may also be stored in a node of a blockchain.
Step S204, the hit rate of the target code-fetching product stored in the first-level cache is obtained.
Specifically, each code-taking product and the corresponding hit rate are stored in a first-level cache, and in a preset updating time period, the method further comprises the process of updating the hit rate of each code-taking product, and the obtained hit rate of the target code-taking product is the updated current hit rate in the preset updating time period.
Further, the method for updating the hit rate of each code-taking product in the first-level cache comprises the following steps:
acquiring a product number of a target code-taking product carried by a code-taking request; when the target code-taking product exists in the first-level cache according to the product number, the hit rate of the target code-taking product is increased by a preset value, and the hit rate of other code-taking products is subtracted by the preset value.
In this embodiment, the preset value may be 1, that is, when it is determined that the target code-taking product exists in the first-level cache according to the product number, the hit rate of the target code-taking product is increased by 1, and the hit rate of other code-taking products in the first-level cache is subtracted by 1, so as to update the hit rate of each code-taking product in the first-level cache.
In one embodiment, when it is determined that the target code-taking product does not exist in the first-level cache, the target code-taking product is added to the first-level cache, the hit rate of the target code-taking product in the first-level cache is recorded as 1, and the hit rate of other code-taking products in the first-level cache is subtracted by a preset value of 1.
Step S206, when the hit rate of the target code-taking product in the first-level cache is determined to meet the preset requirement, the product number of the target code-taking product and the preset splicing prefix for identifying the second-level cache are obtained.
Specifically, when the hit rate of the target code-taking product in the first-level cache is determined to be larger than a preset hit rate threshold, determining that the hit rate of the target code-taking product in the first-level cache meets a preset requirement. And further, after determining that the hit rate of the target code-taking product in the first-level cache meets the preset requirement, acquiring the product number of the target code-taking product and the preset splicing prefix for identifying the second-level cache.
Step S208, the product number and the preset splicing prefix are spliced to obtain a code-fetching identifier corresponding to the target code-fetching product.
Specifically, since the secondary cache cannot be directly identified according to the product code, a preset splicing prefix which can be used for identifying the secondary cache should be obtained, 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-taking product is D12345 and the corresponding preset prefix is spliced to be the pro fit_redeposition_code, the product number and the preset prefix are combined and spliced, and the obtained CODE-taking identifier is D12346-pro fit_redeposition_code. It can be understood that the product numbers of different code-taking products are different, but the preset splicing prefix is used for identifying the secondary cache, and the preset splicing prefix set for different code-taking products can be the same or different.
Step S210, determining a secondary cache corresponding to the target code-taking product according to the code-taking identification.
Specifically, a splicing prefix is preset for identifying the secondary cache, and the secondary cache corresponding to the target code-taking product can be determined by further combining with the product number.
The second-level cache stores the exchange code attribute information corresponding to each code-taking product, including exchange codes, exchange code states, exchange code effective periods, exchange code ineffective periods and the like. The state of the exchange code indicates whether the exchange code is available, the effective period of the exchange code indicates the effective time and the effective duration of the exchange code, the failure period of the exchange code indicates the failure time of the exchange code, and when the failure time is reached, the corresponding exchange is not reusable.
And step S212, when the secondary cache is determined not to be empty, extracting the exchange code corresponding to the target code-taking product from the secondary cache.
Specifically, after the secondary cache of the target code-taking product is obtained, whether the secondary cache is empty is judged. And when the secondary cache is determined to be non-empty, extracting the exchange code corresponding to the target code-taking product from the secondary cache.
In one embodiment, when the secondary cache is determined to be empty, a redemption code corresponding to the target code-taking product is extracted from the database. Meanwhile, the prompt information that the secondary cache of the target code-taking product is empty is pushed to a message queue, and the secondary cache of the target code-taking product is supplemented according to the prompt information, namely, the exchange code state, the exchange code effective period, the exchange code ineffective period and the like corresponding to the target code-taking product are stored in the secondary cache corresponding to the target code-taking product.
In the product code-fetching method, the code-fetching request is received to obtain the target code-fetching product corresponding to the code-fetching request, and the hit rate of the target code-fetching product stored in the first-level cache is obtained. When the hit rate of the target code-taking product in the first-level cache meets the preset requirement, the product number of the target code-taking product and the preset splicing prefix used for identifying the second-level cache are obtained, and the product number and the preset splicing prefix are spliced to obtain the code-taking identifier corresponding to the target code-taking product. And further determining a secondary cache corresponding to the target code-taking product according to the code-taking identification, and extracting the exchange code corresponding to the target code-taking product from the secondary cache when the secondary cache is determined to be non-empty. The progressive acquisition of the redemption code is realized through the set first-level cache and second-level cache, so that the redemption code corresponding to the target redemption code product can be directly acquired from the second-level cache in the memory according to the redemption code acquisition request without real-time acquisition depending on data, the burden of a database is reduced, the occurrence probability of database hot block problems is reduced, and the redemption code acquisition efficiency is further improved.
In one embodiment, the method for determining that the hit rate of the target code-taking product in the first-level cache meets the preset requirement specifically comprises the following steps:
Obtaining a preset hit rate of a preset number of standard code-taking products;
according to the value of each preset hit rate, the preset hit rates of the preset number are arranged to obtain a preset hit rate queue;
acquiring 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 with the hit rate of the target code-taking product;
when the hit rate of the target code-taking product is determined to be larger than the preset hit rate threshold, determining that the hit rate of the target code-taking product meets the preset requirement.
Specifically, the preset hit rates of the preset number of standard code-taking products are sequenced according to the value of each preset hit rate, a sequenced 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 to be a preset hit rate threshold. The preset number may be set by a user or determined based on a service requirement, and is randomly determined from the determined value range, in this embodiment, the preset number is 10, and the ordered preset hit rate queue includes 10 preset hit rates, and the minimum value of the 10 preset hit rates is extracted to determine the preset hit rate threshold.
Further, by comparing the preset hit rate threshold with the hit rate of the target code-taking product, when the hit rate of the target code-taking product is determined to be larger than the preset hit rate threshold, the hit rate of the target code-taking product is determined to meet the preset requirement, namely, the product number of the target code-taking product can be further acquired and the preset splicing prefix used for identifying the secondary cache can be indicated, and therefore the secondary cache which can be used for determining the corresponding secondary cache of the target code-taking product is spliced.
In this embodiment, the minimum hit rate is determined from the preset hit rates corresponding to the plurality of standard code-taking products, and the minimum hit rate is determined as a preset hit rate threshold value, so as to compare with the hit rate of the target code-taking product, and when the hit rate of the target code-taking product is determined to be greater than the preset hit rate threshold value, it is indicated that the hit rate of the current target code-taking product meets the preset requirement. The progressive acquisition based on the first-level cache and the second-level cache is realized, the database is not needed, the pressure of the database can be reduced, and the acquisition efficiency of the exchange code is improved.
In one embodiment, a method for code fetching of a product is provided, comprising the steps of:
acquiring hit rates of all code-fetching products in the first-level cache in a preset updating time period;
Acquiring a preset hit rate threshold;

when the code-taking product with the hit rate smaller than the preset hit rate threshold exists, deleting the code-taking product and the corresponding hit rate from the first-level cache, and deleting the exchange code attribute information of the code-taking product from the second-level cache.
Specifically, the hit rates of all code-taking products in the first-level cache are obtained through a preset updating time period, and compared with a determined preset hit rate threshold value, so that a corresponding comparison result is obtained. When the code-taking product with the hit rate smaller than the preset hit rate threshold value exists in the first-level cache according to the comparison result, deleting the code-taking product and the corresponding hit rate from the first-level cache, and deleting the exchange code information corresponding to the code-taking product from the second-level cache.
The purpose of setting the first-level cache and the second-level cache is to directly obtain the exchange code corresponding to the target code-taking product from the memory without completely depending on a database, so that the problem of database hot blocks is reduced, when the code-taking product with the hit rate smaller than the preset hit rate threshold exists in the first-level cache, the code-taking product is indicated to be requested to be taken fewer times and not belong to the hot code-taking product, the code-taking product is not required to be set to be obtained in a progressive way by combining the first-level cache and the second-level cache, the corresponding exchange code can be directly read from the database, the number of the created caches can be reduced, and the burden on a cluster where the current cache is located, namely a Redis cluster is reduced.
In this embodiment, by comparing the hit rates of all the code-taking products in the first-level cache with the preset hit rate threshold, when there is a code-taking product with a hit rate smaller than the preset hit rate threshold, the code-taking product and the corresponding hit rate are deleted from the first-level cache, and the exchange code attribute information of the code-taking product is deleted from the second-level cache, so as to reduce the number of caches created and the burden of the cluster where the current cache is located.

Specifically, the current code-taking time of each code-taking request of the code-taking product is recorded, the last code-taking time of each corresponding code-taking product is obtained, the time interval between the current code-taking time and the last code-taking time of the code-taking request is calculated, and the interval time is compared with a preset code-taking time threshold value to generate a corresponding comparison result. When the code-taking product with the interval time larger than the preset code-taking time threshold is determined according to the comparison result, deleting the code-taking product and the corresponding hit rate from the first-level cache, and deleting the exchange code attribute information of the code-taking product from the second-level cache.
In the actual operation promotion activities, when there is a holiday in hot section, the code-taking products which are promoted correspondingly are different from the code-taking products which are promoted on normal working days or rest days because the different code-taking products and the corresponding exchange codes are set based on different service demands. After the holiday of the hot festival is finished, the corresponding promotion operation activities of the code-taking product which correspondingly carries out specific promotion are cancelled, and it can be understood that the code-taking product and the corresponding hit rate are deleted from the first-level cache, and the exchange code attribute information of the code-taking product is deleted from the second-level cache by calculating the time interval between the current code-taking time of the request code and the last code-taking time and comparing the time interval with the preset code-taking time threshold value, and when the determined time interval is larger than the preset code-taking time threshold value, the code-taking product is not the hot product promoted in the holiday of the hot festival.
Further, in one embodiment, the method further comprises:
acquiring the creation time of a secondary cache;
and determining the creation time of the secondary cache as the calculation basis of the protection time of the secondary cache.
Specifically, if a secondary cache of a certain code-taking product is built, the condition of eliminating the cache may be satisfied immediately, and in order to avoid the problem that the secondary cache is deleted immediately after being built, and thus frequent operation occupies resources, a protection time needs to be given. And recording the time for creating the secondary cache, wherein the time is used as a basis for calculating the protection time.
In this embodiment, by calculating the interval time between the current code-taking time and the last code-taking time, and comparing the interval time with the preset code-taking time threshold, when it is determined that there is a code-taking product whose interval time is greater than the preset code-taking time threshold, the code-taking product and the corresponding hit rate are deleted from the first-level cache, and the exchange code attribute information of the code-taking product is deleted from the second-level cache, so that the number of caches created and the burden caused to the cluster where the current cache is located can be reduced.
