[0001] The present invention relates to the field of computer technology, and in particular to a page loading method and device. Background Art

[0002] With the rapid development of cloud computing technology and commercial application services, more and more companies are beginning to purchase SaaS (Software-as-a-Service) enterprise services. When using SaaS products and services, users need to customize the WEB interface based on the business model, that is, the business interface supports customization and personalization according to user needs during the SaaS service operation period.

[0003] There are currently two main solutions to meet users' personalized needs for business interfaces:

[0004] 1) Parse different business models through the interface dynamic rendering engine;

[0005] 2) Obtain the information required by the front-end interface through the background service, and return it to the front-end after splicing is completed.

[0006] In the process of implementing the present invention, the inventors found that the prior art has at least the following problems:

[0046] The following is a description of exemplary embodiments of the present invention in conjunction with the accompanying drawings, including various details of the embodiments of the present invention to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for clarity and conciseness, the description of well-known functions and structures is omitted in the following description.

[0047] It should be noted that the embodiments of the present invention are mainly applied to computing application environments and do not rely on any other service systems and can be deployed and integrated independently.

[0048] The terms involved in the present invention are explained as follows:

[0049] Business model: Provides a framework structure for the enterprise from a business perspective to ensure that the enterprise's application system is closely matched with the enterprise's frequently improved business processes.

[0050] Rendering engine: obtains the content of the requested document through the network and displays it in the browser window.

[0051] PaaS (Platform-as-a-Service): A business model that provides the operation and development environment of application services as a service.

[0052] Redirect: Redirect various network requests to other locations through various methods.

[0053] See also Figure 1 , which shows a main flow chart of a page loading method provided by an embodiment of the present invention, comprising the following steps:

[0054] S101: receiving a page loading request, and determining a template model and a resource file corresponding to the page loading request according to feature information in the page loading request;

[0055] S102: Obtain metadata in the template model and resource information in the resource file. If the timestamp of the latest update of the metadata and the resource information is the same, read and return resource location address information of the resource file.

[0056] In the above implementation, for step S101, when the WEB interface needs to be customized, the domain SaaS service client can send a page loading request to the SaaS service server.

[0057] After receiving the request, the resource loading service of the SaaS service will analyze the characteristic information in the request, such as the type of browser, industry information, language used, template model identifier, etc.; then, based on these characteristic information, the template query service is called to determine the template model; for example, if the template model identifier in the request is 1 and the language used is Chinese, the Chinese version of template model 1 is determined.

[0058] The number of template models set can be multiple to increase the diversity of page display, for example:

[0059] 1) Different browsers correspond to different template models; for example, IE browser-Template 1, Google Chrome-Template 2, Firefox-Template 3;

[0060] To obtain the browser type, you can use the getBroserInfo method, for example:

[0061]

[0062] 2) Different industries correspond to different template models; for example, medicine - template 4, physics - template 5, chemistry - template 6;

[0063] 3) Different languages ​​correspond to different template models; for example, Chinese-template 7, English-template 8, Japanese-template 9.

[0064] The template model mainly records the user's design information for the interface. For details, see Figure 2 As shown, it mainly includes three aspects:

[0065] 1) Basic information of the template, used to describe the summary information of the template;

[0066] 2) Template layout information, including layout type and space list, which is used to describe the overall layout of the interface and the display style information of the controls;

[0067] 3) Business object management information, which is used to record the relationship between front-end resources and business model data, and can support data interaction during system operation.

[0068] When designing a business interface, it is usually necessary to lay out the interface. For example, the elements used for layout in HTML include DIV, SPAN, Table, etc. Resource files (files from which the required resources can be read) can create and store various styles, which means that each page control has a place to store its own style.

[0069] It should be noted that direct file reading means searching from the hard disk only when the program is running and needs resources. The resource files are actually still on the hard disk, but the resource files have been mapped to the virtual memory. Compared with directly reading the hard disk files, it has the advantage of fast loading speed. Therefore, the present invention mainly uses resource files for resource acquisition. For the specific method of acquiring resource files, please refer to the subsequent Figure 4 The description will not be repeated here.

[0070] For step S102, the template model will be adjusted according to user needs, and the resource file is compiled and generated through the template model and the template file corresponding to the template model. When the template model changes, the resources in the corresponding resource file will usually change accordingly, specifically, the update timestamp or version changes.

[0071] In the prior art, resource files are compiled for each page record request. If the template model does not change, the compilation of resources in the resource file is repetitive and unnecessary. Based on this consideration, the present invention chooses to determine whether the template model has changed before compiling the resource. If there is no change, it proves that resource compilation is not required.

[0072] Whether the template model has changed depends on whether the timestamp of its last update is the same as (or close to, but the difference is very small) the timestamp of the last update of the resource in the corresponding resource file. For the specific process, see Figure 3 As shown:

[0073] 1) The metadata of the template model is stored in the metadata service. The metadata service can be queried through the identifier of the template model, and the corresponding timestamp can be obtained based on its attribute information.

[0074] Among them, metadata, also known as intermediary data or relay data, is data about data, mainly information describing data properties, used to support functions such as indicating storage location, historical data, resource search, and file records.

[0075] 2) Resource files can be stored in resource containers OSS (Object Storage Service), Baidu Cloud and other cloud services. The present invention mainly uses OSS as an example for explanation. The timestamp of the last update of the required resource file can be obtained through the file version (or timestamp) query service.

[0076] 3) Compare the metadata and the resource's last updated timestamp:

[0077] ① If the two timestamps are the same, it means that the template model has not changed since the last compilation, and the controls, styles and other resources in the corresponding resource file have not changed, that is, there is no need to recompile the resources.

[0078] In this case, the page loading request can be redirected directly to the URL (Uniform Resource Identifier) ​​address of the resource file, or the URL address can be considered to be fed back to the client to eliminate resource compilation time, reduce page rendering time, and improve page loading efficiency.

[0079] ②If the timestamps of the two are different, it means that the template model has been changed, but the resources in the resource file have not been recompiled in time. Specifically:

[0080] Step 1: If the timestamps of the latest updates of the metadata and resource information are different, extract the template file corresponding to the template model according to the identifier of the template model;

[0081] Step 2: compile the template file and the template model to generate compiled resources, and update the resource file through the compiled resources; and

[0082] Step 3: Read and return the resource location address information of the resource file after the resource is updated.

[0083] The template compilation module compiles the template files and template models for front-end resources, and automatically packages the compiled resources into the resource files to update and replace the resources in the resource files; then, the URL address of the updated resource file is returned to the client.

[0084] The template file and the template model here can be in a one-to-one relationship, and the two are similar to test papers and answers, and neither is indispensable. The template file can be a document with a series of personalized settings, for example, a TMP template file that meets the Freemark protocol; and the resource file can include TMP, JS, and HTML files.

[0085] It should be noted that the resources compiled here are for front-end resources. By compiling the front-end resources and template models on the server, and generating an interface and sending it to the front-end, there is no need for the front-end to perform operations such as page splicing, and there is no need for the front-end browser to compile the resources.

[0086] The method provided in the above embodiment can directly return the published resource location address for the unchanged template model before compiling the resources, thereby eliminating the resource compilation time, reducing the page loading time, reducing server consumption, and improving the execution efficiency of the front-end engine.

[0087] See also Figure 4 , shows a schematic flow chart of an optional page loading method according to an embodiment of the present invention, comprising the following steps:

[0088] S401: receiving a page loading request, and determining a template model corresponding to the page loading request according to characteristic information in the page loading request; wherein the characteristic information at least includes an identifier of the template model;

[0089] S402: According to the identifier of the template model, obtain a resource file corresponding to the identifier from a CDN node;

[0090] S403: if the resource file cannot be found in the CDN node, acquiring the resource file corresponding to the identifier from a resource container according to the identifier of the template model;

[0091] S404: Obtain the metadata in the template model and the resource information in the resource file. If the timestamps of the latest updates of the metadata and the resource information are the same, read and return the resource location address information of the resource file.

[0092] In the above implementation, steps S401 and S404 can be respectively referred to Figure 1 The description of steps S101 and S102 is not repeated here.

[0093] In the above implementation, for step S402, the resource file is obtained through the compilation result of the template file and the template model, that is, the file actually requested by the client.

[0094] In order to improve the access efficiency of resource files, the present invention chooses to build CDN nodes (Content Delivery Network) on the network and distributes the resource files in OSS to the CDN nodes.

[0095] See also Figure 3 As shown, the compiled resource file is output to OSS, and the file is distributed to the CDN node through the file publishing service in OSS. Therefore, there can be a mapping relationship between the resource file and the CDN node:

[0096] 1) Many-to-one: multiple resource files are stored on the same CDN node;

[0097] 2) One-to-many: Set up multiple CDN nodes that can complete the same task, and the same resource file will be distributed to these CDN nodes simultaneously. When there are many subsequent page requests, you can choose one from multiple CDN nodes with the same function to provide service, thereby increasing service capacity and improving service efficiency.

[0098] For the above method 2), it usually relies on edge servers deployed in various places. The CDN nodes enable users to obtain the required resource files nearby through the load balancing, content distribution, scheduling and other functional modules of the central platform, and reduce network congestion, thereby improving user access response speed and hit rate.

[0099] In addition to the above-mentioned method of OSS distributing files to CDN nodes, CDN nodes can also request resource file modification timestamps from OSS at a certain interval (e.g. 1s) and compare them with existing resource files to determine whether the stored resources have changed. If there are changes, the new files will replace the old files to achieve resource updates.

[0100] In addition, CDN nodes can be set according to region, usage, etc. Taking regional settings as an example, there are North China 1, North China 2, Northwest 1, East China 2, South China 1, etc.

[0101] Different CDN nodes will respond to different regions and different network requests (page loading requests), and the determination of CDN nodes can be achieved through the client HTTP protocol and load balancing technology; load balancing technology distributes the network traffic as evenly as possible to several servers or CDN nodes that can complete the same task for processing, such as the CDN node with the lowest current processing volume, to avoid the unfavorable situation that some CDN nodes are overloaded while others are idle, which can not only improve the overall network traffic, but also improve the overall performance of the network.

[0102] Resource files are still mainly identified and obtained based on the identifier of the template model, for example, template model 1-resource file 1, and resource file 1 stores information such as the style of template model 1 and corresponding controls.

[0103] There are many ways to read resource files, for example:

[0104] 1) System.Resources.ResourceReader reads resource file information;

[0105] 2) Through the getResource method of the class class of this class;

[0106] 3)Test.class.getClassLoader().getResource, where the location of the resource file is relatively fixed.

[0107] In the above manner, whenever a resource file is needed, it can be read from the CDN node first, so as to improve the file reading speed.

[0108] For step S403, the resource files in the CDN node are all transmitted through OSS, so there may be a situation where some resource files have not been updated. In this case, the load balancing will forward the request to the data source of OSS to obtain the resource files from OSS, specifically, through the identification of the template model.

[0109] The method provided in the above embodiment can achieve the effect of obtaining files nearby by obtaining resource files from CDN nodes, while reducing the number of times files are obtained from OSS, and has the function of reducing network congestion and improving file access response speed and hit rate; however, if the resource file cannot be found in the CDN node, it can also be queried in OSS, thereby ensuring the acquisition of the resource file.

[0110] Here combined Figure 2 , supplement the generation of template model:

[0111] The template model can be developed in a certain way through a single-page application (one page can complete all tasks, and jumping to a new page is not allowed); for example, add, delete, modify, and query the historical business model, and then bind the attributes of the business model to the UI elements through itemkey; for example, the text input box itemkey = 'person', the data in the input box corresponds to the person of the business model.

[0112] The development method here can be JS+html, php, jsp, vue, etc. The present invention mainly uses JS+html method. Compared with other methods, JS+html method is not affected by the page frame.

[0113] The business model attributes here may include business data structures, such as: person, name, old, money; UI elements may include: left alignment, right alignment, color, control type, whether it is required to enter, whether it is read-only, etc.

[0114] The template model can be constructed after calling the template saving service. Compared with the prior art, the template model provided by the present invention supports information management of business objects.

[0115] In addition, the template model can also be modified to meet the user's personalized needs for the WEB interface. Specifically,

[0116] The user performs a change operation on the WEB interface in the client, and the client responds to the change operation by sending a corresponding change request to the SaaS service;

[0117] The SaaS service changes the template model according to the change information in the change request, recompiles the generated resources, and updates the resource files; then it feeds back the URL address of the updated resource files to the client;

[0118] The client receives the new URL address and opens the changed interface. The overall process realizes the visualization of the template design interface and the interactive operation at runtime.

[0119] See also Figure 5 , shows a system 500 applied to PaaS services, specifically including: design module, template model, template engine, resource publishing; wherein:

[0120] 1) Design module 501, used to complete the modification operation of the business template model and bind the attributes of the business template model to the interface UI elements;

[0121] 2) Template model 502, calling the template saving service, saving the template designed by the design template, and constructing a template model for recording the user's design information on the interface.

[0122] 3) Template engine 503, used to determine the corresponding template model and resource file for the page loading request transmitted by the client, and compare whether the timestamps of the last update of the two are the same;

[0123] If they are the same, the resource file URL address is fed back to the client;

[0124] If they are not the same, it indicates that the template model has changed, but the resource file has not been updated. The template model and template file need to be compiled to generate compiled resources, and the resources in the resource file are updated; and the URL address of the resource file after the resource is updated is sent to the client.

[0125] 4) Resource publishing 504, distributing resource files in OSS to CDN nodes, so as to facilitate the subsequent extraction of resource files from CDN nodes, improve the efficiency of resource file acquisition, reduce the number of visits to OSS, and reduce network congestion.

[0126] PaaS is a cloud service between IaaS and SaaS models, which provides an environment for the development and operation of applications. IaaS mainly provides infrastructure services such as virtual computing, storage, and databases, SaaS provides users with cloud-based applications, and PaaS provides developers with an environment for building applications. Therefore, the present invention is mainly implemented in a PaaS device to obtain page services from SaaS.

[0127] The present invention provides a set of devices that can parse business models, compile and implement front-end static resources, dynamically publish front-end resources, and support dynamic query of templates. The device can be deployed and integrated independently of the business system as a PaaS service. In addition, the device segments the interface generation cycle, provides a template designer for users to customize the interface online, and saves the structure of the template model while supporting the ability to dynamically compile, refresh, and publish front-end resource files, thereby improving the efficiency of compilation to a certain extent.

[0128] See also Figure 6 , which shows a schematic diagram of main modules of a page loading device 600 provided by an embodiment of the present invention, including:

[0129] The request processing module 601 is used to receive a page loading request and determine a template model and a resource file corresponding to the page loading request according to feature information in the page loading request;

[0136] If there are multiple CDN nodes, the current request volume to be processed by each CDN node is determined, and the CDN node that currently processes the least number of requests is extracted.

[0137] In the implementation device of the present invention, the request processing module 601 is also used for:

[0138] If the resource file cannot be found in the CDN node, the resource file corresponding to the identifier is obtained from a resource container according to the identifier of the template model.

[0139] In the implementation device of the present invention, the version comparison module 602 is further used for:
