Design and implementation of knowledge sharing system based on WeChat small program

Aiming at the needs and characteristics of the development of knowledge sharing, this paper designs and realizes the solution of knowledge sharing with the rise of the sharing economy as the background and the small program as the carrier. According to functions, the knowledge sharing system can be divided into six modules: video resource module, article resource module, question answering module, credits module, auditing module and recommendation module. The system adopts the C/S (client/server) architecture as the overall architecture. The backend relies on the tencent cloud server and the platform functions was accomplished through Java, JavaScript, MySQL database and the special languages of WeChat small program: WXML and WXSS. The classical collaborative filtering algorithm is used to recommend different resources to different users. This small program meets the user's need to acquire knowledge anytime and anywhere. It effectively solves the present problems in knowledge sharing and has great significance to the further development.
