Background
When a user accesses a Web information system (or application system) using a browser, it is often necessary to call APIs local to the user's computing device, such as dynamic libraries, COM components, system APIs, and the like. However, for security reasons, various browsers are prohibited from directly accessing the local path as well as various types of local devices. In order to achieve the access of the browser to the local file and the device, a common manner in the industry is to add a client to take charge of the above functions. When the executed function logic in the browser needs to call some local files as well as local device functions, the interface provided by the client is called through a local address (localhost). And the client returns the execution result to the front end of the browser. Meanwhile, the execution flow of more high-performance load is arranged to be executed at the client side due to the performance of the browser, so that the performance bottleneck problem caused by the browser is solved.
However, as the number of services carried by the Web information system is increased, the function requirements are fragmented, the client needs to customize different interfaces and iterate new functions continuously to cope with different requirements, the file size of the client is increased continuously, and the network distribution cost is high; meanwhile, the client side often adopts a pure native scheme, is influenced by factors such as platform constraint or security interception, and is difficult to update remotely.
Therefore, there is a need for an easy-to-update-and-maintain method to enable access to local resources by a browser.

Detailed Description
Before describing embodiments of the present application in further detail, the terms and terminology involved in the embodiments of the present application will be described, and the terms and terminology involved in the embodiments of the present application will be used in the following explanation.
A browser is a software application for accessing the internet, which is presented as an interface that can be understood and manipulated by a user by parsing HTML, CSS, and JavaScript codes of a web page.
JSON (JavaScript Object Notation) is a lightweight data exchange format consisting of key-value pairs, the keys being bracketed with double quotation marks, the values being strings, numbers, boolean values, arrays, objects (sets of key-value pairs) or null.
The JS (JavaScript) interface is a contract defining the properties and methods of objects, providing a standardized way to agree on the communication and interaction between objects.
Component execution engine refers to a tool that parses and executes component code, including without limitation React, vue, angular.
The present application will be described in more detail with reference to examples.
Example 1
As shown in fig. 1, a method for accessing local resources based on function components includes the following steps:
the browser obtains the call information. The call information includes call function names, call contexts, and the like.
The interaction interface of the browser end transmits the calling information to the component execution engine. In this embodiment, the interactive interface is a JS interface, and converts the call information into JSON format, and transmits the converted call information to the component execution engine in a remote call manner.
The component execution engine operates on a user computer where the browser is located, and searches whether a corresponding function component exists in a local cache according to the calling information;
if the function component exists locally, the component execution engine loads and executes the function component, and an execution result is returned to the browser; the component resources are mutually independent, and the component execution engine executes a plurality of components in parallel.
If the function component does not exist locally, the component execution engine acquires a dynamic update package of the function component from a remote component server, installs the dynamic update package, acquires an execution result of the function component after the installation is completed, and returns the execution result to the browser;
if the component server does not have a dynamic update package of the function component, the component execution engine passes the error information to the browser.
Example two
As shown in FIG. 2, the component execution engine includes a loader, a local cache module manager, a remote cache module manager, an execution engine, and a number of general-purpose components. The general component is prefabricated in the component execution engine in the form of a WASM component, and comprises and is not limited to a file IO operation module, a thread sheet analysis engine module and the like, so that the function of being used after being unpacked is realized.
Example III
In a scene sensitive to performance, a JS component for realizing business logic and a WASM component for realizing performance are integrated into a dynamic module update package, and a component execution engine downloads and installs the dynamic module update package to a local. The JS component serves as an entry for calling a function, and the component execution engine calls the WASM component or other JS components in the JS component. The JS component and the WASM component are respectively components written in JavaScript language and WebAsssembly language.
The method has the advantages that when the module execution engine executes the JS module to process business logic, the high performance of the WASM module is called to process some performance-sensitive tasks, performance and response speed are improved, and better user experience is provided.
Example IV
The operation of deriving Excel at a time is described as an example:
the browser requests the home page information from the service server (business web server), and the browser displays the received home page information;
after the client logs in, an Excel operation is triggered and exported, and the interaction interface converts the calling information into a JSON format and transmits the JSON format to the component execution engine.
The local cache module manager searches whether the corresponding function component exists in the local cache, and if not, the remote cache module manager requests the corresponding function component from a component server deployed at a remote end.
If the component server exists the function component, the component server returns its dynamic update package.
If the component server does not have the function component, the component server returns an error message.
After receiving the dynamic update package, the component execution engine installs and caches the dynamic update package locally so that the next time a call is required, no further requests need to be made to the component server. Then, the component execution engine executes the logic in the installed dynamic update package, and returns the execution result, i.e., excel file stream, to the browser.
The browser displays the Excel file.
