Research And Development Of Cross-platform Digital Textbook System Based On Uni-app

In recent years,the Internet is becoming more and more popular in people's life,and all kinds of terminals become indispensable tools in people's life.The Internet accelerates the development of digital textbooks.Mobile terminals have opened a new mode of study and life for people.Laptops,tablets,smart phones and other brand-new tools are appearing more and more in people's life.However,due to the various forms of mobile terminals and the increasing popularity of smart phones,the current digital textbook system in the market can no longer meet the growing needs of people,which seriously affects the convenience of people's use and also increases the development cost of cross-platform digital textbook system.In view of the above situation,this paper proposes to apply uni-app technology into the field of digital teaching materials,which has different product forms and organizational characteristics from traditional teaching materials.Completed the system front-end online learning,background management research and development.Through the construction of this system,the cross-platform technology can adapt to the current demand in the field of digital textbooks,improve the learning efficiency of students,and establish a fully functional,convenient,efficient and convenient digital textbook system for teachers and students on campus.The system provides services for teachers and students in schools and provides assistance to improve the learning efficiency of students.The research work of this topic is mainly divided into five aspects: one is to investigate the research background and development status of the cross-platform digital textbook system;the other is to investigate the related technologies used in the cross-platform digital textbook system;Thirdly,the demand analysis of cross-platform digital textbook system is carried out.Fourthly,design a cross-platform digital textbook system based on uni-app framework;Fifth,the cross-platform digital textbook system is realized based on uni-app and Spring Boot technology.In this paper,the cross-platform digital textbook system is analyzed and designed in detail,focusing on the system functional structure,system architecture,data structure,domain model and user rights.A cross-platform digital textbook system based on uni-app is developed.Through the custom component to improve the flexibility of the code,at the same time to solve the adaptive problem,through the code confusion,shielding the right button and other ways to solve the problem of page protection,through the encryption algorithm to solve the problem of content protection,through the rich text,plug-in and other forms to enhance the teaching of the system.Finally,it effectively solves the problems such as inconvenient use of multi-platform and insufficient teaching characteristics.Through this paper,we can understand the development status of the cross-platform digital textbook system and the implementation scheme of the system,which has a certain reference value for the development of other cross-platform digital textbook system or similar fields and similar technologies.At the same time,the analysis of non-functional requirements of cross-platform digital textbook system can provide ideas for the development of other digital textbook systems.
