A private domain e-commerce platform consumption discount right and interest automatic control CDN cache method

Abstract

The application provides a CDN cache method for automatically controlling consumption discount rights and interests of a private domain e-commerce platform, comprising the following steps: S1, an operator creates a purchase area page through a "decoration operation platform" system, configures corresponding activity information of the area in the page, and sets the start and end time of the activity; S2, a system manager analyzes and intervenes the time of activity preheating and post-retention through area traffic data; S3, when the operator puts the configured activity page into a terminal channel, if there is no expired cache data, the page content will be immediately responded to the user when the user accesses a certain activity; S4, if the CDN has no cache data, it is returned to the application service, the application service parses the activity information, calculates the cache time required by the activity page through a formula, sets it, and responds to the user; S5, if there is no user access, the worker automatically scans the activity data in the system once every 5 minutes, actively renders HTML, sets the effective buffer time, and pushes it to the CDN server.

Description

Technical Field

[0001] The present invention relates to the field of e-commerce, and in particular to a method for automatically controlling CDN caching of consumer discount benefits on a private domain e-commerce platform. Background Art

[0002] The "Decoration Operation Platform," part of the private B2C e-commerce operation platform, provides the ability to build and operate H5 event pages. These pages include a "Consumer Discount Benefits" page, a City A Consumer Discount Benefits page, and a City B Consumer Discount Benefits page for regionally restricted events. Operators create these pages, configure them with different event information and coupons, and then publish them within the mini-program for regular users to purchase.

[0003] Because we offer flash sales, we face high concurrency and heavy traffic. During promotional periods, excessive traffic can cause service crashes or lags, resulting in business losses and a poor user experience. A common industry practice is to place promotional pages on a CDN and configure an expiration time on the server's Nginx to manage the page's validity period.

[0004] Currently, we modify the Nginx configuration file to support the CDN cache time for each "Consumer Discount Benefits Grab Event Page." Because each event page has different promotional strengths and audiences, configuring each page would require numerous configuration items, and the configuration would become fixed. Once an event ends, we need to manually modify the configuration file to reduce the CDN cache time or shut down the CDN and restart the server so that the next event information can take effect quickly after the current event page ends.

[0005] As the number of activity pages increases and the activity cycles vary across regions, we have to modify machine configurations more frequently, which in turn increases the chances of restarts and human errors. Furthermore, the next activity on that page can't take effect quickly after the current activity ends. Summary of the Invention

[0006] The present invention provides a method for automatically controlling CDN caching for consumer discount benefits on a private domain e-commerce platform. Based on the page technology provided by the Node service, a solution for automatically controlling CDN caching in rush-buy page scenarios is created.

[0007] The technical problem to be solved by the present invention is achieved through the following technical solutions:

[0008] The present invention provides a method for automatically controlling CDN caching of consumer discount benefits on a private domain e-commerce platform, comprising:

[0009] S1. The operator creates a page for the rush purchase area through the "Decoration Operation Platform" system, configures the activity information corresponding to the area (including consumption coupons) on the page, and sets the start and end time of the activity;

[0010] S2. System managers analyze the warm-up and post-retention time of intervention activities through regional traffic data;

[0011] S3. When the operator puts the configured activity page into the terminal channel, when a user visits a certain activity (a fixed URL such as https: / / xx.xx.com / h5 / xfq-chengdu.html), the page will first return to the CDN node to search for the current activity page. If there is unexpired cached data, the page content will be immediately responded to the user;

[0012] S4. If the CDN does not cache the data, it returns it to the application service. After querying the page data and rendering the HTML, the application service parses the activity information and calculates the required cache time for the activity page using a formula. After setting the required cache time, it responds to the user.

[0013] S5. If there is no user access, to prevent a sudden influx of users from causing CDN back-to-origin and service unavailability, the Worker automatic task automatically scans the active data in the system every 5 minutes, actively renders HTML, sets the effective buffer time, and pushes it to the CDN server.

[0014] Preferably, the Koa framework is used to automate data processing of the cache device and build a Node universal rendering service, and the routing, HTTP universal package, function universal package, template rendering engine and other capabilities in the framework are used.

[0015] Preferably, the CDN automatically returns to the source when the user accesses the site:

[0016] 1A. Through the routing service router.get(' / h5 / :activity.html',async(ctx)=>{...dosomeing}) we query the CMS content configuration data through the :activity in the URL;

[0017] 1B. Render the HTML structure of the current page from floor to module through the koa-art-template template, and build in the consumption voucher activity (coupon Json data) to get a complete HTML page;

[0018] 1C. Parse the details of the activity on the current page, read the start and end times of the activity, and then call the manual intervention data of the configuration platform to find the activity preheating time and activity post-time of the current activity (:activity);

[0019] 1D. If the current time of the user's visit is before the activity start time minus the "warm-up time" or after the end time plus the post-time, set ctx.set('Cache-Control', `max-age=0`) through the Koa ExtendableContext context object to set the cache time to zero;

[0020] 1E. If the user's current access time is between the preheating time and the post-processing time, the cache time = ("preheating time" + "activity time" + "post-processing time") - ("current time" - "preheating time"). This formula is used to set the preheating time before responding to the complete HTML content to the CDN, and then responding to the browser.

[0021] Preferably, the process of Node Worker automatic task scanning is:

[0022] 2A. When the service starts, a scheduled task device is created to periodically scan the list of valid active pages in the CMS system.

[0023] 2B. Assemble a fixed URL of https: / / xx.xx.com / h5 / xfq-xxx.html using the activity information found.

[0024] 2C. Render a complete page using the activity details and the current page content using steps 1B. Then, set the Cache-Control duration in the Response using steps 1D and 1E.

[0025] 2D. Push the page content with the URL https: / / xx.xx.com / h5 / xfq-xxx.html to the CDN operator.

[0026] Preferably, the cache time setting method is:

[0027] 1) Before the activity warm-up time, preventive operations that do not cache pages temporarily adjust activity data to prevent data leakage;

[0028] 2) After the current time enters the warm-up time, the cache time that should be set at the current time point is automatically calculated; as time passes, the cache time set for the response will be shortened;

[0029] 3) When accessing the page at the current time, the activity on the page has ended and the CDN cache needs to be cleared to ensure that the next activity configuration can take effect immediately.

[0030] The beneficial effects of the present invention are: the rush purchase page can automatically hit the CDN cache before the event starts, and the CDN cache is automatically cleared after the event ends. At the same time, it solves the problem that the next activity configured after the end of the previous activity can quickly preview the effect of the activity (without cache) and confirm the accuracy of the activity. It ensures that the next activity will not cause users to not see the latest activity information due to the long CDN cache time of the previous activity or too late manual maintenance. The present invention reduces the time cost of manually maintaining the CDN when the system supports rush purchase pages in more regions. At the same time, the automatic push of Worker tasks can better improve the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Figure 2 It is a data processing flow chart of the automatic cache device of the present invention.

[0033] Figure 3 It is a schematic diagram of the cache time setting algorithm of the present invention. DETAILED DESCRIPTION

[0034] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0035] Figure 1 This is the system data flow structure diagram of this embodiment. The solution design of the present invention is to build a set of mechanisms for automatically processing CDN cache, design the system management capability of "grab the active page CDN manual intervention service", and at the same time, by adding "automatic cache time calculation setting processing device", it can automatically calculate the reliable cache time that can be set for the "active page" at the current time point according to the page activity content. And provide a "Node Worker timing task device" that can automatically calculate the cache time that should be set for the current time activity according to the manual intervention results of the "active page" or the changes in the page activity operation content, and actively push it to the CDN server. It can effectively ensure that the data obtained by users from the CDN is valid and real-time. It reduces the pressure on large concurrent application servers and reduces the cost of servers.

[0036] 1) The operator creates a rush purchase area page through the "Decoration Operation Platform" system, configures the corresponding activity information (including consumption coupons) for the area on the page, and sets the start and end time of the activity.

[0037] 2) System managers analyze the warm-up and post-retention time of intervention activities through regional traffic data.

[0038] 3) When the operator puts the configured activity page into the terminal channel, when the user visits a certain activity (a fixed URL such as: https: / / xx.xx.com / h5 / xfq-chengdu.html), the page will first return to the CDN node to search for the current activity page. If there is unexpired cached data, the page content will be immediately responded to the user.

[0039] 4) If the CDN does not cache the data, it returns to the application service. After the application service queries the page data and renders the HTML, it will parse the activity information and use a formula to calculate the required cache time for the activity page. After setting it, it responds to the user.

[0040] 5) If there are no users accessing the site, to prevent a sudden influx of users from causing CDN back-to-origin service unavailability, the Worker automatic task automatically scans the active data in the system every 5 minutes, actively renders HTML, sets an effective buffer time, and pushes it to the CDN server.

[0041] Figure 2 This is a data processing flow chart for the automated caching device of the present invention. The Koa framework is used to build the Node universal rendering service, utilizing the framework's routing, HTTP universal package, function universal package, template rendering engine, and other capabilities.

[0042] MB: indicates the preheating time before the event starts. System administrators follow up on the activity intensity and traffic estimates and intervene in advance to set the default setting to 30 minutes before the event starts.

[0043] MA: Indicates that the post-time related to the end of the event is set to a positive number n (CDN retains n minutes after the end of the event), and set to a negative number (CDN cache is not set n minutes before the end of the event).

[0044] S: Activity start time.

[0045] E: Event end time.

[0046] 1) The user visits the (xx consumption voucher page) and causes the CDN to actively return to the source.

[0047] a) Through the routing service router.get(' / h5 / :activity.html',async(ctx)=>{...dosomeing}) we query the CMS content configuration data through the :activity in the URL.

[0048] b) Render the HTML structure of the current page from floor to module through the koa-art-template template, and build in the consumption voucher activity (coupon Json data) to get a complete HTML page.

[0049] c) Analyze the activity details on the current page and read the activity's start and end times. Then, use the manual intervention data from the configuration platform to find the activity's pre-heat time and post-activity time.

[0050] d) If the current time of the user's visit is before the activity start time minus the "warm-up time" or after the end time plus the post-time, set ctx.set('Cache-Control', `max-age=0`) through Koa's ExtendableContext context object; set the cache age to zero.

[0051] e) If the user's current access time is between the preheating time and the post-processing time, the cache time = ("preheating time" + "activity time" + "post-processing time") - ("current time" - "preheating time"). After setting the preheating time, the complete HTML content is responded to the CDN, and then responded to the browser.

[0052] 2) Node Worker automatic task scanning process

[0053] a) When the service starts, a scheduled task device is created to periodically scan the list of valid active pages in the CMS system.

[0054] b) Assemble a fixed URL of https: / / xx.xx.com / h5 / xfq-xxx.html using the activity information found.

[0055] c) Render a complete page using the activity details and the current page content using step b) in 1), and then set the Cache-Control cache duration in the Response using steps d) and e) in 1).

[0056] d) Push the page content with the URL https: / / xx.xx.com / h5 / xfq-xxx.html to the CDN operator.

[0057] Figure 3 This is a schematic diagram of the cache time setting algorithm of the present invention. This algorithm reasonably sets the CDN time based on the promotion activity cycle to achieve the effect of automatically controlling the CDN page expiration cleanup and cache.

[0058] 1) Before the activity warm-up time, we do not cache pages to prevent operations from temporarily adjusting activity data to prevent data leakage.

[0059] 2) After the current time enters the warm-up period, the cache time that should be set at the current time point is automatically calculated. As time passes, the cache time set for the response will be shortened.

[0060] 3) When accessing the page at the current time, the activity on the page has ended and the CDN cache needs to be cleared to ensure that the next activity configuration can take effect immediately.
