Fig. 4 schematically illustrates a schematic diagram of generating access priority lists for respective business presentation web pages according to an embodiment of the present disclosure. This operation is described below with reference to fig. 4.
As shown in fig. 4, generating access priority lists for respective business presentation web pages is done jointly by a computing system, a model system, and a flow system.
The computing system executes core computation and manages a computation queue and a period according to a rule engine and a computation strategy; the model system provides a model analysis method that provides a number of prefabricated models including, but not limited to: XGBoost, lightGBM, NN, TFlite, and the like, extracting features, performing model evaluation, matching a proper calculation model, and simultaneously executing model management, conversion and deployment. The process system builds task workflow by combining operators and model methods, matches analysis models according to service characteristics, maps service scenes to the analysis models, and outputs calculation results.
According to an embodiment of the present disclosure, first, a relevance value between each visitor and each service presentation web page is determined according to service tag data and visitor tag data, which specifically includes: establishing a calculation task flow for generating a correlation value; and sequentially executing the calculation task flow so as to generate a correlation value between each visitor and each business presentation webpage according to the business label data and the visitor label data. And then, sequencing the service display webpages according to the magnitude of the correlation value between the visitor and the service display webpages for each visitor so as to generate an access priority list of the visitor for the service display webpages.
According to an embodiment of the present disclosure, determining a relevance value between each visitor and a respective business presentation web page based on business tag data and visitor tag data includes:
determining a preset calculation model matched with the service characteristics according to the service tag data; and inputting the business label data and the visitor label data into a preset calculation model, and outputting a correlation value between each visitor and each business presentation webpage.
According to embodiments of the present disclosure, the specific operations are: the business label data and the visitor label data are converted into abstract analysis features through a data conversion engine and are input into a model system, the model system determines a preset calculation model matched with the business features according to the business label data, a flow system builds a calculation task, the business label data and the visitor label data are input into the preset calculation model, and a correlation value between each visitor and each business display webpage is output. And mapping the result data to an analysis model, and sequencing the service display webpages according to the magnitude of the correlation value between the visitor and the service display webpages for each visitor in the analysis model to generate an access priority list of the visitor for the service display webpages.
In the course of implementing the present disclosure, it is found that: conventional web caching is only applicable to caching static resources and is low in accuracy. The data is cached in a non-timely manner. When the cache amount exceeds the maximum storage space, the cache is frequently managed by using the LRU policy, and the cache hit rate is low. For this problem, the following technical means can be adopted, for example.
Scheme one: and the PWA (Progressive Web App) technology is used for carrying out the separated cache of the data and the static resources, and the page can be completely and rapidly presented when relevant resources are prestored in the cache in cooperation with the cache degradation strategy aiming at the request data.
Scheme II: and caching and storing by using a Native terminal, rendering data by using an NSR mode, and enabling the webpage display speed to be superior to that of the PWA scheme.
However, the above technical solution has some drawbacks, for example, in the first solution, the data cache is bound with the page cache, and the page cache adopts the LRU mechanism, so that most of the cache hit rates are low. When the cache fails to hit, it may degenerate to conventional page requests. In the scheme II, the dependence on the Native terminal is extremely high, the Native has poor compatibility in running, the NSR implementation scheme is complex, the cost is high, the history page needs to be customized and modified, and the feasibility is low; and the cache mechanism still adopts the LRU mechanism, so that the cache hit rate is low.
Based on the above problems, the present disclosure provides a PWA-based web page caching method, which includes:
receiving a first access request for a service display webpage from a visitor;
in response to the first access request, acquiring static resources and dynamic resources from resource links related to the business presentation web page so as to return the static resources and the dynamic resources to the visitor;
and judging whether to cache the static resource and the dynamic resource according to the webpage caching strategy, wherein the webpage caching strategy is generated by the webpage caching strategy generation method.
According to embodiments of the present disclosure, service works and Cache Storage API techniques are employed in performing the above-described methods. The Service Worker is used for a client agent between the browser and the network, and can intercept, process and respond to HTTPS requests flowing through. By setting Cache Storage API, processing of static and dynamic resource files can be controlled so that the Service Worker can provide resources from the cache to the web application, even in an offline environment. Meanwhile, the dynamic resources flow through the Service workbench and can be managed by the cache like the static resources, so that the overall offline cache of the dynamic resources and the static resources is realized.
According to the embodiment of the disclosure, whether to cache the static resources and the dynamic resources is judged according to the webpage caching strategy, a personalized caching strategy can be formulated according to the preference of each visitor (for example, according to a certain visitor, which resources need to be cached and which resources do not need to be cached), according to the personalized caching strategy, the webpage resources which are frequently accessed by the user can be cached, so that when the user accesses the webpage again, the webpage resources can be directly obtained from the cache, the request resources can be quickly returned to the user, the response speed of the webpage is accelerated, and the user experience is improved. Meanwhile, by adopting Service works in combination with Cache Storage, the separation and decoupling of static resource Cache and dynamic Cache resources are realized, and the disadvantages of limited Cache range and limited H5 offline package scene of a browser are overcome.
According to an embodiment of the present disclosure, further comprising:
receiving a revisit request for a business presentation webpage from a visitor;
judging whether static resources and dynamic resources related to the business display web page exist in the browser cache;
under the condition that static resources and dynamic resources exist in the browser cache, the static resources and the dynamic resources are obtained according to a preset updating rule.
According to an embodiment of the present disclosure, obtaining static resources and dynamic resources according to a preset update rule includes:
under the condition that the time interval between the first access request and the second access request is smaller than the preset time interval, acquiring static resources and dynamic resources from the cache;
under the condition that the time interval between the first access request and the second access request is larger than or equal to a preset time interval, static resources and dynamic resources are obtained from resource links related to the service display webpage, namely, the static resources and the dynamic resources are degraded into online requests.
