Description

Technical Field

[0001] The present invention relates to the field of computer technology, and in particular to an nginx-based flash sale control method, system and electronic equipment. Background Art

[0002] In order to increase business growth and active users, e-commerce websites often need to launch flash sales to attract users to visit the website. When designing a flash sales system, the most important thing is to ensure that the system is stable when a large amount of traffic arrives, that the flash sales items are not oversold, and that the flash sales are fair.

[0003] The existing technology usually uses nginx+redis architecture to design the flash sale system, using nginx to achieve high concurrency to ensure that the flash sale system will not be overwhelmed by the sudden large flow; using redis (remote dictionary server) to achieve high performance and atomic inventory deduction. However, the number of flash sale objects in the same period is usually not large, and the inventory is small. The duration of the entire flash sale process is very short, and once the limited number of products are sold out, the entire flash sale activity is over.

[0004] Based on the architecture of the flash sale system in the prior art, on the one hand, nginx does very little front-end logic (for example, limiting traffic, controlling traffic, etc.), and does not bring the advantages of nginx to the extreme; on the other hand, when using redis, it is necessary to maintain the redis cluster. During the idle period of the flash sale, the redis server is wasted, increasing the operation and maintenance cost. In addition, there will be the problem of flash sale hotspots. If the inventory of the flash sale objects is unevenly scheduled, it is likely to cause the flash sale service to crash, seriously affecting the user experience.

[0005] How to make full use of the advantages of nginx itself to complete the flash sale process, effectively eliminate flash sale hotspots, and improve the overall throughput of the flash sale service is an urgent problem to be solved. Summary of the invention

[0075] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0076] Example 1

[0077] A method for controlling spikes based on nginx, such as Figure 1-3 As shown, the flash sale control method may include the following steps:

[0078] Step S11: reading the information of the published flash sale object, wherein the information of the flash sale object includes the inventory of the flash sale object;

[0079] Step S12: Synchronize the inventory to the nginx instance;

[0080] Step S13: receiving a flash sale request from a user for the flash sale object;

[0081] Step S14: controlling the nginx instance to execute the inventory deduction logic according to the flash sale request, wherein the inventory deduction quantity in the deduction logic corresponds to the quantity of the flash sale objects in the flash sale request.

[0082] The nginx is a lightweight, high-performance server that can support reverse proxy and email proxy, etc., and supports high concurrent data traffic.

[0083] The so-called flash sale refers to a sales method in which when an online seller releases some low-priced goods, all buyers rush to buy them online at the same time.

[0084] In this embodiment, the flash sale objects may be flash sale products released by online sellers, and the flash sale products may involve various categories, such as clothes, food, household appliances, etc.

[0085] Specifically, after the online merchant edits and publishes the information of the flash sale products, the flash sale product information is added to the flash sale product message queue, and the flash sale product message queue can store the information of the flash sale products. The information of the flash sale products may include the total inventory of the flash sale products and the newly added inventory of the flash sale products. The inventory of the flash sale products refers to the number of flash sale products that can be effectively flash sold.

[0086] Furthermore, the newly added inventory may be a positive number, a negative number or 0.

[0087] Specifically, when the newly added inventory is a positive number, the total inventory is increased based on the original total inventory; when the newly added inventory is a negative number, the total inventory is decreased based on the original total inventory; and when the newly added inventory is 0, the total inventory is equal to the original total inventory.

[0088] Next, the inventory of the flash sale product may be synchronized to the nginx instance, that is, the inventory information of the flash sale product may be stored in the nginx instance.

[0089] Furthermore, the nginx instance may be one or more.

[0090] Preferably, the number of nginx instances can be set to multiple, and the multiple nginx instances form an nginx cluster to jointly complete the flash sale task.

[0091] As a non-limiting implementation in this embodiment, the step S12 may specifically include step S121: allocating the inventory to each of the nginx instances according to a preset ratio, so that each of the nginx instances has a distributed inventory.

[0092] Inventories can be allocated to different nginx instances based on their operating performance (e.g., the number of messages processed per unit time, data processing speed, etc.). In other words, a larger proportion of sub-inventory can be allocated to nginx instances with good operating performance, and a smaller proportion of sub-inventory can be allocated to nginx instances with poor operating performance.

[0093] In addition, to facilitate operation, maintenance and control, you can also select multiple nginx instances with the same operating performance to form an nginx cluster.

[0094] As another non-limiting implementation in this embodiment, preferably, the step S12 may specifically include step S122: evenly distributing the inventory to each of the nginx instances, so that each of the nginx instances has equal sub-inventory.

[0095] It is understandable that those skilled in the art can adaptively set the number of nginx instances constituting the nginx cluster according to the specific operation and maintenance costs and the requirements of the application scenarios, and the embodiments of the present invention do not limit this.

[0096] When storing data, each nginx instance can store the inventory information of a specific product according to the data structure of [product ID, total inventory, total inventory of the current instance, deducted inventory], and can adjust the inventory information in the data structure according to the newly added inventory in the flash sale product message queue.

[0097] Preferably, the inventory information may be stored in a shared dictionary in an nginx instance, where the shared dictionary is a component in the nginx instance that may store memory data.

[0098] It should be noted that the content and order of the data structure in which the nginx instance stores inventory information can be adjusted according to specific needs, and the embodiment of the present invention does not limit this.

[0099] Next, when the user clicks on the flash sale object, for example, when the user clicks on the "buy" button corresponding to the flash sale product in the webpage or APP, it indicates that the user has issued a flash sale request for the flash sale object.

[0100] According to the flash sale request, the nginx instance is controlled to execute the deduction logic of the inventory. When there are multiple nginx instances, one or more nginx instances can be controlled to execute the deduction logic of the sub-inventory according to the flash sale request. The deduction inventory quantity in the deduction logic corresponds to the quantity of the flash sale objects in the flash sale request.

[0101] When the deduction logic is successfully executed, an inventory deduction log will be generated. The log structure can be: [time, user ID, inventory ID, total inventory, current instance inventory, current deduction inventory]. By recording the log, the inventory deduction can be traced back, so that when a problem occurs, it can be traced back according to the log.

[0102] Next, step S15 may be executed: generating an order. Specifically, an order may be generated by using parameters [time, user ID, product ID, inventory ID, deduction of inventory]. After the order is generated, the user may be waited to complete payment for the order within a preset payment time.

[0103] If the user fails to complete the payment within the preset payment time or issues a cancellation instruction for the order, it indicates that the order has failed. Specifically, the data structure of the cancellation instruction may be [order number, canceled inventory quantity].

[0104] If the order is cancelled, the inventory can be adjusted according to the quantity of the flash sale objects in the cancelled order, and the inventory can be rolled back to the nginx cluster again.

[0105] Specifically, inventory rollback can be achieved by using the instruction incr_N written in the scripting language lua embedded in nginx.

[0106] Furthermore, the flash sale control method may also include the following steps:

[0107] Step S16: Determine whether the flash sale duration of the flash sale object is greater than a preset expiration time;

[0108] If the judgment is yes, execute step S17: control the nginx instance to delete the information of the flash sale object.

[0109] Those skilled in the art can flexibly set the length of the preset expiration time according to different types of flash sale activities and different types of goods, and can adaptively adjust the preset expiration time of the next flash sale activity according to the effect of this activity, and the embodiments of the present invention are not limited to this.

[0110] The embodiment of the present invention can realize high-concurrency and high-performance inventory deduction logic only through nginx, which maximizes the advantages of nginx itself, and there is no access to redis, which effectively saves operation and maintenance costs; in addition, by evenly distributing the inventory of the flash sale object to each nginx instance, each of the nginx instances has an equal inventory. Therefore, the flash sale hotspots can be eliminated through the inventory deductions of multiple nginx instances, avoiding the downtime of the flash sale service caused by uneven inventory scheduling of the flash sale objects, and improving the user experience. Furthermore, this embodiment can delete expired flash sale product information in a timely manner, saving storage space, and reducing the interference of redundant product information on the operating performance of nginx.

[0111] Example 2

[0112] A method for controlling spikes based on nginx, such as Figure 4 As shown, the flash sale control method in this embodiment is a further improvement based on embodiment 1.

[0113] Furthermore, step S122 may also include step S123: scheduling the sub-inventory in the nginx instance at preset time intervals so that the sub-inventory is maintained equal in each of the nginx instances, wherein the scheduling includes increasing the sub-inventory, decreasing the sub-inventory, or maintaining the sub-inventory unchanged.

[0114] In this embodiment, the preset time can be set to 30-200ms, preferably, the preset time is 100ms.

[0115] Furthermore, in order to ensure that the execution process of each scheduling is traceable, the step S123 may further include a step S124: generating a scheduling log for scheduling the sub-inventory.

[0116] When the scheduling is specifically performed, atomic deduction scheduling can be performed in units of m inventories, and the scheduling inventory deduction logic of all nginx instances is executed at the same time, where m is a positive integer. Preferably, the value of m is 10.

[0117] In this embodiment, the number of schedulable inventory is counted based on the schedulable inventory of each nginx instance and the inventory information of the current instance. For an nginx instance, the schedulable inventory refers to the inventory that can be adjusted to other nginx instances. The scheduling process can be completed only in the local intranet, and the logic is very simple. Each scheduling can be completed within milliseconds to ensure fast and timely scheduling.

[0118] Furthermore, the total amount of the inventory may be verified at preset verification time intervals to ensure that there is no problem that a product is successfully sold out but the inventory is not deducted accordingly due to network failure or other reasons.

[0119] In this embodiment, the preset verification time may be 50-200 ms, and preferably, the preset verification time is 100 ms.

[0120] When the verification process finds an inventory deduction error, the local log of each nginx instance and the scheduling log are checked. If the test result shows that the inventory in a certain nginx instance has been deducted but has not been correctly identified as deducted, the next round of scheduling process can be used to replenish the inventory in the nginx instance that has been deducted but has not been correctly identified as deducted, to ensure that each nginx instance has equal inventory and that the remaining inventory in the nginx instance meets the inventory reserve requirements for the flash sale.

[0121] This embodiment ensures that the inventory of each nginx instance is uniform and sufficient during the flash sale activity through real-time inventory scheduling and inventory verification, further reducing the risk of flash sale service downtime.

[0122] Example 3

[0123] A method for controlling spikes based on nginx, such as Figure 5 As shown, the flash sale control method in this embodiment is a further improvement based on embodiment 1 or embodiment 2.

[0124] In order to further improve the randomness and fairness of the flash sale, the step S14 may be improved. The step S14 may be performed according to the following specific steps:

[0125] Step S141: Determine whether the difference between the time when the flash sale request occurs and the preset flash sale time is greater than a preset threshold;

[0126] If the judgment is no, then executing step S142: delaying the preset flash sale time by a preset adjustment value to obtain the time for executing the flash sale operation;

[0127] Step S143: determining whether the current time has reached the time for executing the flash sale operation;

[0128] If the judgment is yes, execute step S144: control the nginx instance to execute the deduction logic of the inventory.

[0129] In specific implementation, if the current time has not reached the preset flash sale time, it will return that the flash sale time has not yet arrived. If it is close to the preset flash sale time or has reached the preset flash sale time, the above-mentioned delay process can be performed.

[0130] As a non-limiting implementation in this embodiment, for example, the preset threshold value can be set to 2s. When the difference is less than or equal to 2s, the preset flash sale time can be delayed by the delay instruction ngx.sleep written in the script language lua embedded in nginx to obtain the execution time of the flash sale operation. In other words, after adding the delay, the inventory deduction logic is not executed at the preset flash sale time, but is executed at the time when the flash sale operation is executed.

[0131] Preferably, the execution time of the flash sale operation can be set to: preset flash sale time - current time + a random number within 1000ms.

[0132] It is understandable that the preset threshold value can be dynamically adjusted to meet the needs of different flash sale occasions, for example, the flash sale threshold value can also be set to 1s, 3s, 4.5s, 6s, etc. The embodiment of the present invention is not limited to this.

[0133] In this embodiment, after the preset flash sale time is delayed, it can be ensured that users with slower networks or users who are far away from the server also have the opportunity to buy products in flash sales, which effectively improves the randomness and fairness of flash sales and improves user experience.
