[0050] Reference Figure 2 , an embodiment of the present application provides a method for obtaining external logical data of a web page, the method for obtaining external logical data of a web page comprising:

[0051] Step S100, loading resource data;

[0052] Step S200, determining whether the resource data is loaded successfully;

[0053] Step S300, if unsuccessful, switch the source address and return to the step of loading resource data until the resource data is loaded successfully.

[0054] In this embodiment, the specific application scenario may be:

[0055] When a user browses a web page, the web page needs to obtain external logical data to construct the web page. During the browsing process of the web page, due to network problems or resource failures, the external logical data cannot be obtained or the acquisition speed is slow, resulting in the inability to display the web page, resulting in a poor user experience.

[0056] The specific steps are as follows:

[0057] Step S100, loading resource data;

[0058] In this embodiment, the system loads resource data, which is external logic data. The resource data includes logic data and interface components required for web page construction, and is used for website web page construction.

[0059] In this embodiment, the development framework of the website webpage can be React, Vue, Angular, Alpine, Preact, LitElement, Stimulus and Ember, etc. Among them, the Vue framework is preferred in this embodiment. Vue is a progressive framework for building user interfaces. Vue has a bottom-up layer-by-layer application. The core library of Vue is in the view layer, which is easy to integrate with third-party libraries or existing projects. On the other hand, when used in combination with a modern tool chain and various supporting libraries, Vue can provide drivers for complex single-page applications.

[0060] Specifically, the step S100 includes the following steps S110-S130:

[0061] Step S110, obtaining an external database;

[0062] In this embodiment, the system obtains an external database, wherein the external database is an open source database whose source code is open to the outside world, and developers can modify or use it based on its original design. Specifically, the open source database includes: MSSQL server, MySQL, Oracle, PostgreSQL, MongoDB, etc.

[0063] In this embodiment, the system may obtain the external database by pre-connecting the web page to the external database, wherein the pre-connection may be a corresponding access standard for accessing the database or a corresponding access component.

[0064] Step S120, importing the resource data file in the external database;

[0065] In this embodiment, the resource data file is a file that carries the logical data and interface components required for web page construction. Preferably, in the website page developed by the front-end VUE framework, the system introduces the resource data file in the external database by introducing the required logical data and interface components in the open source database through the link tag. The external introduction link will become a monitorable dynamic file on the browser.

[0066] Step S130: Load the resource data in the resource data file on demand.

[0067] In this embodiment, the system loads the resource data in the resource data file on demand based on the construction requirements of the website webpage. Since the resource data required for the construction of different webpages is different, the resource data is loaded according to the requirements of the webpage, thereby speeding up the acquisition of resource data. For example, a website includes two webpages A and B, and the external database includes files X, Y, and Z. The resource files required to be loaded by webpage A are files X and Y in the external database, and the resource files required to be loaded by webpage B are files Y and Z in the external database. When the user opens webpage A, the system loads files X and Y in the external database.

[0068] In this embodiment, the system loads the resource data in the resource data file on demand by polling. For example, the system uses IF function polling judgment to load data on demand.

[0069] Specifically, the step S130 includes the following steps S131-S132:

[0070] Step S131, determining the required resource data in the resource data file;

[0071] In this embodiment, the system determines the required resource data in the resource data file by polling. Preferably, in the website page developed by the front-end VUE framework, the system uses IF function polling to determine the required resource data in the resource data file.

[0072] Step S132: loading the required resource data.

[0073] In this embodiment, the system loads the required resource data. For example, a website includes web page A, and the external database includes files X, Y, and Z. The resource files required to be loaded by web page A are files X and Y in the external database. When a user opens web page A, the system loads files X and Y in the external database.

[0074] Step S200, determining whether the resource data is loaded successfully;

[0075] In this embodiment, the system determines whether the resource data is loaded successfully. If the resource data is loaded successfully, the web page interface is loaded normally; if the resource data fails to load, the process proceeds to step S300.

[0076] In this embodiment, the system determines whether the resource data is loaded successfully by determining whether the resource data is loaded successfully or by determining whether the resource data is loaded overtime. In this embodiment, the system uses a custom algorithm to determine whether the data source has timed out or has failed.

[0077] Specifically, the step S200 includes the following steps S210-S220:

[0078] Step S210, monitoring the loading of the resource data to obtain loading information;

[0079] In this embodiment, the system monitors the loading of the resource data to obtain the loading information, wherein the loading information includes information of successful loading, information of failed loading and information of loading timeout. Preferably, on the website page developed by the front-end VUE framework, the watch monitoring property of the VUE framework is used to monitor whether the data component has been loaded successfully.

[0080] Step S220: Based on the loading information, determine whether the resource data is loaded successfully.

[0081] In this embodiment, the loading information includes information on successful loading, information on failed loading, and information on timed loading. If the loading information is information on successful loading, it is determined that the resource data has been loaded successfully; if the loading information is information on failed loading or timed loading, it is determined that the resource data has been loaded unsuccessfully.

[0082] Specifically, the step S220 includes the following steps S221-S222:

[0083] Step S221, determining whether the loading information contains information of resource loading failure or resource loading timeout;

[0084] In this embodiment, the resource loading timeout information is when the system monitors the loading of the resource data and exceeds the preset time without obtaining other loading information, it is determined that the resource loading timeout has occurred. The preset time can be set according to needs, such as 10 seconds, and no specific limitation is made here.

[0085] Step S222: If the loading information includes information about resource loading failure or resource loading timeout, it is determined that the resource data loading has failed.

[0086] In this embodiment, if the loading information is information indicating a successful loading, it is determined that the resource data has been loaded successfully; if the loading information is information indicating a failed loading or a timed-out loading, it is determined that the resource data has been loaded unsuccessfully.

[0087] Step S300, if unsuccessful, switch the source address and return to the step of loading resource data until the resource data is loaded successfully.

[0088] In this embodiment, if the system determines that the resource data is successfully acquired, the web page interface is loaded normally; if the resource data fails to load, the system switches the source address and reloads the resource data that failed to be acquired. The source address is a preset data source address, and the source address also includes the resource data required by the website web page. In reloading the resource data that failed to be acquired, the resource data that failed to be acquired is loaded on demand, and the necessary files are loaded on demand to speed up the loading speed.

[0089] Specifically, the step S300 includes the following steps S310-S330:

[0090] Step S310, selecting a new data source address;

[0091] In this embodiment, the new data source address is a preset data source address, and the new data source address also includes resource data required by the website webpage, wherein the external database includes a preset number of data source addresses, and the new data source address is selected from the preset number of data source addresses. The preset number of data source addresses includes more than two, and the preset number can be set according to the needs, and is not specifically limited here.

[0092] Specifically, the step S310 includes the following steps S311-S312:

[0093] Step S311, obtaining a preset backup data source;

[0094] In this embodiment, the preset backup data source is a preset data source address, and the system obtains the preset backup data source, wherein the preset backup data source also includes resource data required by the website webpage.

[0095] Step S312: selecting the new data source address from the preset backup data sources.

[0096] In this embodiment, the external database includes a preset number of preset backup data sources, and the new data source address is selected from the preset backup data sources, wherein the preset backup data sources also include resource data required by the website webpage.

[0097] Step S320, creating an address tag at the new data source address, and importing the resource data based on the address tag;

[0098] In this embodiment, the system creates an address tag at the new data source address, and based on the address tag, introduces the resource data, that is, introduces the resource data that failed to be obtained above at the new data source address. Preferably, under the website page developed by the front-end VUE framework, a file is re-created to introduce the address tag, insert the head tag, and introduce the resource data.

[0099] Step S330, returning to the loading resource data, loading the resource data.

[0100] In this embodiment, similar to step S100 above, the system reloads the resource data in the new data source address.

[0101] In this embodiment, the system determines whether the resource data loaded at the new data source address is loaded successfully. If successful, the web page interface is loaded normally. If the resource data fails to load, the system switches the source address and reloads the resource data that failed to be acquired, until the resource data is successfully acquired and the web page is successfully loaded, which effectively reduces the error probability of the website page and improves the user experience.

[0102] The present application provides a method, system, device and storage medium for acquiring external logical data of a web page. Compared with the prior art in which a web page cannot be displayed due to network problems or resource failure, resulting in poor user experience, in the present application, resource data is loaded; it is determined whether the resource data is loaded successfully; if unsuccessful, the source address is switched, and the step of loading resource data is returned until the resource data is loaded successfully. That is, in the present application, after the resource data is loaded on the web page, it is determined whether the resource data is loaded successfully. In the case of failure to load the resource data, the source address of the acquisition source is automatically switched until the resource data is successfully acquired and the web page is successfully loaded, thereby improving the user's web page usage experience.

[0103] Based on the first embodiment, the present application further provides another embodiment. In the another embodiment, referring to Figure 3, under the HTML static website page developed by the front-end VUE framework, build a loadJsCss function, in which the script tag and link tag are initialized by the document.createElement method. In this way, the script and link introduced from the outside will become a dynamic file that can be monitored on the browser. After that, the IE browser will provide the onload attribute and the webkit kernel browser will provide the sheet attribute to determine whether the file is loaded successfully. At this time, you can make an if judgment in the watch monitoring hook function of the VUE.js framework to confirm whether the js and css imported files in onload and sheet are loaded successfully. If the import is successful, it will return a true logical value to skip this step and load the web page normally; if it is unsuccessful, build a poll function to make an if judgment. When the obtained logical value is not true, it will enter the failed if judgment and change a source file address. Among them, the source file address is changed using three function methods: document.createElement, setAttribute, document.getElementsByTagName("head")[0].appendChild(link). Recreate a file import address tag and insert it into the head tag. The browser will load the head tag first. Then call the loadJsCss function again to start initializing the loading of the web page, and use the document.write method in JavaScript to load the necessary files on demand. The watch hook function will continue to monitor whether the onload and sheet attributes return a true logical value. If not, the poll function will continue to be called to perform polling and source switching operations until the external source file is successfully loaded and then skip polling and no longer call the poll function.

[0104] It should be noted that according to the order in which HTML files are loaded by a web page, the main content of the website in the body tag will not be loaded until the script tag and link tag in the head tag are loaded. Therefore, under this rule, you can use external source files (script tags and link tags in the source code) that are introduced by continuous polling to optimize the web page loading process.

[0105] The present application also provides a web page external logic data acquisition system, the web page external logic data acquisition system comprising:

[0106] Loading module, used to load resource data;

[0107] A judgment module, used to judge whether the resource data is loaded successfully;

[0108] The switching module is used to switch the source address if it is unsuccessful and return to the step of loading the resource data until the resource data is loaded successfully.

[0109] Optionally, the switching module includes:

[0110] The address selection module is used to select a new data source address;

[0111] A source changing module, used for creating an address label at the new data source address, and introducing the resource data based on the address label;

[0112] The loop loading module is used to return the loaded resource data and load the resource data.

[0113] Optionally, the site selection module includes:

[0114] A data source acquisition module is used to acquire a preset backup data source;

[0115] A selection module is used to select the new data source address from the preset backup data sources.

[0116] Optionally, the loading module includes:

[0117] Database acquisition module, to acquire external database;

[0118] An import module, used for importing resource data files in the external database;

[0119] The on-demand loading module is used to load the resource data in the resource data file on-demand.

[0120] Optionally, the on-demand loading module includes:

[0121] A determination module, used to determine the required resource data in the resource data file;

[0122] The demand loading module is used to load the resource data of the demand.

[0123] Optionally, the judging module includes:

[0124] A monitoring module, used to monitor the loading of the resource data and obtain loading information;

[0125] The loading judgment module is used to judge whether the resource data is loaded successfully based on the loading information.

[0126] Optionally, the loading judgment module includes:

[0127] An information determination module, used to determine whether the loading information contains information about resource loading failure or resource loading timeout;

[0128] The determination module is configured to determine that the resource data loading has failed if the loading information contains information indicating that the resource loading has failed or that the resource loading has timed out.
