s12, initializing the main application and registering the sub-application;
s13, setting an application management module in the main application, and realizing communication between the main application and the sub-application through the application management module.
Specifically, referring to fig. 2, a schematic architecture diagram of an integrated system based on micro front end framework construction according to this embodiment is provided. The main application comprises a plurality of functional modules, such as main application initialization, registration sub-application, route distribution, application management service, application loader and the like; the sub-application may include a plurality of sub-application terminals, such as sub-app, which implement a communication function with the main application through the application loader. The main application initializes and registers the sub-application, then the route distribution receives the change of the page route URL, so as to search the sub-application according to the change of the page route URL to the application management service, and the searched sub-application is loaded by the application loader. The framework construction based on the micro front end, such as initializing a main application, registering a sub-application, etc., are well known to those skilled in the art, and will not be described herein.
It should be noted that, in the initial stage of the whole construction project, the main application needs to be loaded first, and after the main application is loaded successfully, each sub-application is registered in the micro-application registry of the main application. When the page routing URL changes, if the page routing URL satisfies the configuration rule of the main application (set in the application management service), loading of the sub-application is started. An exemplary portion of this embodiment is shown in fig. 3.

The advantage of the Hash routing mode is that it, although it appears in the URL, is not included in the HTTP request, has no effect on the backend at all, and therefore there is no problem to change the post-Hash refresh.
By setting the hook function, the application program can filter all messages and events at the system level and access messages which cannot be accessed under normal conditions. The nature of the hook function is a program to process system messages, which are suspended into the system by system calls. The embodiment sets a mount hook function, can construct a page route, and initializes the page of the sub-application.
Still further, in this embodiment, step S3, the method for performing technical engagement on the integrated system after modification includes:

Specifically, in this embodiment, the micro-application portal is a Kebab case named micro-application portal; the sub-application portal is named as a sub-application portal of a Pascal case.
S32, setting up a micro-application registration rule in the micro-application inlet so as to load the micro-application through the micro-front-end framework of the main application. Specifically, in this embodiment, the micro application portal hits the micro application registration rule of the Main application, accesses the micro application are loaded through the micro front end framework of the Main application, the micro application portal is agreed to be used for integration of a general page, the interface may refer to fig. 5, and when the user clicks the sub application menu, the sub application page is loaded in the Main area.
S33, building a sub-application menu in the sub-application entry so as to load the sub-application through the sub-application menu. Specifically, in this embodiment, the sub-application portal is directly accessed through the sub-application, and does not pass through the micro front end framework of the main application, and the sub-application portal is agreed to be used for page integration with high style complexity, so that style pollution does not exist in the sub-application portal.
The principle of creating the micro-application portal using the Kebab case rule and creating the sub-application portal using the Pascal case rule is well known to those skilled in the art. The embodiment can solve the problem of style pollution of the main application and the sub-application in the micro front end integration process by establishing the convention.
Further, in this embodiment, step S4, the method for constructing deployment and configuration settings for the integrated system includes:
s41, performing micro-front-end construction deployment on the integrated system based on jenkins and dockers. Specifically, in this embodiment, the deployment is continuously integrated and automatically built based on jenkins for the main application and the sub application, respectively; and configuring the running environments of the main application and the sub-application based on the docker, and compiling a front-end application.
S42, carrying out configuration setting of a server reverse proxy server on the integrated system based on the nginx.
The present embodiment provides a micro front end deployment technique based on jenkins+docker+nginx, where jenkins is responsible for continuous integration, automated construction; the dock is responsible for configuring the running environments of the main application and the sub-application and compiling the front-end application; the nginx is used as a reverse proxy server to realize configuration based on convention. The micro front end deployment technology adopted by the embodiment is consistent with the deployment of the main application and the sub application, so that the complexity of an integrated system can be reduced to a certain extent.
This embodiment provides a specific example, as shown in fig. 6, to illustrate the micro front end deployment technique employed.

The invention provides a technology for solving user mode sharing of micro front end integration, which is based on OAuth2.0 and adds authentication logic between sub-application and main application. When a user accesses the integrated system, firstly, an authorization code is acquired from an authentication center; then telling the authorization code to the back end of the system, enabling the back end to go to an authentication center through the authorization code to obtain a token, and storing the token in a browser storage; then, the main application and the sub-application acquire system authorized resources according to the token, and the main application and the sub-application share the same token, so that the user state consistency of the integrated system is ensured.
OAuth is an open network standard for authorization (authorization) that allows users to authorize third party applications to access information they store on another service provider without the need to provide a user name and password to the third party mobile application or to share all of their data. The OAuth protocol has the characteristics of simplicity, safety and openness: whether an OAuth service provider or an application developer, is easy to understand and use; the information such as the user key is not related, so that the method is safer and more flexible; OAuth can be implemented by any service provider and used by any software developer.

And, the flow of the unified authentication of the sub-applications is approximately as follows: the browser accesses the sub-application with the access-token, and the back end of the sub-application acquires the token and checks the token; the unified identity authentication center checks the token, and returns the user information to the back end of the sub-application if the token passes the check; the back end of the sub-application searches whether a corresponding user exists, if so, the user login information is stored, and otherwise, the login abnormality is prompted. The browser acquires data, the back end of the sub-application searches whether the user token exists and is valid, if the user token exists and is valid, the data is returned, the browser successfully acquires the data, otherwise, the browser redirects to a login page, and if the login page is out of date, a new access-token is acquired by using a refresh-token.
