judging whether the access time in the local cache exceeds the effective time length: if not, the local data is valid; if yes, the data needs to be obtained again and cached.
Optionally, as an embodiment of the present invention, the method further includes:
when the front end is set to change the local cache resource, the content and the name must be changed at the same time.
Optionally, as an embodiment of the present invention, the static resource includes resource files such as pictures, videos, HTML, CSS, fonts, and the like, which need to be loaded on the page.
Optionally, as an embodiment of the present invention, the allocating system resources and setting the maximum caching time of the static resources by the backend according to the caching control rule includes:
self-defining a filter for setting the maximum cache time by using a back-end server;
and importing the filter into a configuration file loaded by a page.
Optionally, as an embodiment of the present invention, the method further includes: the CSS style sheet is set to load before html.
In order to facilitate understanding of the present invention, the principle of the configuration method for implementing the speed increase of the front-end page loading of the cloud platform according to the present invention is combined with the process of caching resources of the cloud platform in the embodiment, so as to further describe the configuration method for implementing the speed increase of the front-end page loading of the cloud platform according to the present invention.
Specifically, the configuration method for realizing the loading speed improvement of the front-end page of the cloud platform comprises the following steps:
s1, classifying the static resources, uniformly placing the static resources at a designated position, and controlling a cache strategy mainly through attributes such as max-age, lastidentification and expires in the cache-control; setting static resources to be not overtime within 1 year through a back-end service, namely setting the maximum cache time to be one year;
in this embodiment, the backend server adopts a tomcat server, and the configuration is as follows:
the method comprises the steps that a Filter is customized, wherein the Filter is used for setting maximum cache time (max-age), and a setHeader instruction is used for setting the max-age (31536000) in a cache-control, wherein the unit of an attribute (max-age) is second; xml document uses this filter;
therefore, the static resource which is requested and responded for the first time is directly loaded by using the local cache when being requested for the next time, a new static resource strategy is formed, the static resource is not required to be requested like a back-end server, and the response pressure of the back-end server is reduced.
S2, when the back-end server configures the response cache strategy, the front-end loading data generally loads all static resources at one time, so the pressure of the first loading is large; therefore, the loading on demand is set at the front end of the cloud platform in the embodiment when the loading is carried out for the first time, the front end is divided into corresponding independent modules according to functions, the modules are put into the universal module, and when the universal module is loaded once, other functional modules are used, repeated loading is not needed.
The lazy loading is carried out during front-end loading, and when the page is loaded with the data, the residual part can be loaded in a delayed manner by combining the amount of the displayed content due to the limitation of the display area.
This may increase the first load speed of each page. After the first loading of the service is completed, the second loading is performed, and most of the static resources are acquired from the local cache through the static resource policy set in the step S1, so that the speed of accessing the page again can be greatly increased, and the page is opened at millisecond level.
S3, after the methods in S1 and S2 are carried out, simultaneously, the optimization of codes is carried out by combining the loading mechanism of the browser; rendering of the GUI of the browser is carried out preferentially, namely the JS related codes are placed at the last of the text of the html document, and the JS engine processing flow is placed at the last. The browser is preferentially caused to perform GUI rendering. Meanwhile, in order to obtain a better user experience effect, the CSS style sheet is rendered before the html text, so that a page rendered by the GUI has CSS styles, and the page is more attractive.
In S1, the static resource is already put into the user' S local when the static resource is first loaded in the front page. When the static resource is updated in the cloud platform, the user cannot acquire the updated content (unless the user manually clears the local cache, the user is not advised to do so); in order to solve the problem, in this embodiment, when modifying a static resource, the name of the static resource is modified at the same time, so that due to the change of the resource name, the resource is treated according to a new resource, the new resource is cached in the local from a back-end service for the first time, and an existing end construction tool is used, when modifying the static resource each time, the reference in the code is modified without being modified by an engineer, which can be used in this embodiment: front-end construction tools such as webpack or glup;
s5, a cache mode and an on-demand loading mode of static resources are described in S2, S3 and S4, and the loading speed of a front-end page in the cloud platform is increased; however, in the cloud platform, a part of resource data is stored in a database form, which does not belong to static resources, cannot be cached, and some sensitive information is not suitable for caching, so that the resource needs to send an http request in an API manner to acquire the resource, and real-time data is acquired from a host of the cloud platform or a database in a management system through a service layer of the cloud platform; when the cloud platform loads the data, accelerated loading is also carried out in a cache mode; when certain resources are frequently accessed, the resources are cached in the local of the back end, so that the resources do not need to be acquired from each cloud platform host or database; certainly, the fidelity of the cached data is important, and how to judge whether the cached data in the local area is invalid can be performed by the following method:
a. when the data is cached, adding a modification time variable, comparing the modification time of the data stored in the local with the modification time of the real data when a user accesses the secondary data each time, if the modification time is consistent with the modification time of the real data, the local data is valid, and if the modification time is inconsistent with the real data, the data in the local is updated;
b. when data is cached, adding an effective duration variable, when a user accesses secondary data, if the effective duration is exceeded, acquiring the data again for caching, and if the effective duration is not exceeded, the data is effective;
when both a and b exist, the priority of decision b is a, namely when the modification time or the effective duration of the resource exists, whether the local data is effective or not is judged according to the effective duration.
As shown in fig. 2, the system 200 includes:
a back-end resource allocation unit 210 configured to allocate system resources for a back-end and to cache the static resources locally by setting a maximum cache time of the static resources;
a front-end initial loading unit 220 configured to set a mode of loading on demand and lazy loading for a front-end page;
the recording flow control unit 230 is configured to set a JS engine processing flow for performing browser GUI rendering preferentially and performing JS engine processing finally in front-end page loading;
the dynamic resource loading unit 240 is configured to place a resource with a higher access frequency in the non-static resource into the local cache, and determine whether the local data is valid according to the modification time or the valid duration of the resource.
